Asus Zenfone 2 ZE551ML

Anonymous

Best phone I had so far, plain and simple. Had it for 4 years now (while having at the same time 2 generation of iPhones as secondary phones) and even the battery still works great and gives almost a full day. It’s a shame that Android phones are soooo bad at OS updates. Google+Builders+Carriers should be forced to give further support, if just for security reasons, Apple outranks you badly on that front. Having that said, ASUS rocks!, great manufacturer/designer overall (coming from and IT guy).

After many years of great service from this phone (at least no Freeze and Auto Restart like SAMSUNG ) From my hand to my 6yrs old daughter ownership. It finally RETIRED on Sept 11 2019. Not bad. Next month I will pass her my Oppo R9s which is 99.8% like new. Now surveying the best budget phone with 710 chipset.

My problem is that I can't turn my phone off. Every time when I tray to turn it off it starts again. It does't matter if I use power button or double click on the screen.

The phone is OK to me, but my major problem is the issues of battery. I use to change the battery but unfortunately I loss the phone completely in the process. I only own it's scrapped now.

I have using this phone about 3 yrs, and only 1 time i replacing the battery. Overall, this is a good phone. But i am not recommended for gaming because it's draining fast (MLBB/PUBG/Free Fire), only 3 hrs than you got 0%. Compare to samsung A50 (i just bought it), zenfone 2 has better sound performance (speaker & headset). No more issue for my Zenfone 2 ZE551ML.

zen ui laucher is a home launcher u cant delete it because your are using but most of the zen apps are useless i bet u can delete some of them i think

I'm very happy with this phone. Browsing or streaming is flawless. I have been using it for almost 4yrs now, very easy to DIY in case of issues. I have replaced the screen 3 times, all by myself. I have replaced the speaker twice, the SIM card holder twice. All the parts are cheaply available on Aliexpress. The battery is still holding charge reasonably. My model is 4g ram 64gb rom. There's is slight overheating though. I have just ordered for zenfone max pro m2, just as a backup to my zenfone2 551ml. ASUS is great

Phone is hang over after 3 month. my side this phone is bad feature. i will never buy Asus Phone.

So long to this awful phone! My ASUS Zenfone 2 bricked after about 3 years out of nowhere, while on charge and after being restarted. It gave me issues after a week I bought it. Had to have it serviced after a week because the SIM slot apparently was messed up and was not recognizing the SIM card (the SIM card slot kept giving me issues anyway, every way too often the SIM card would displace itself inside the slot having to re-insert it, losing connectivity in moments where I needed to stay connected). The plus are the good interface, the easy possibility to work with firmware updates and the audio/screen features. What is terrible? SIM slot that doesn't hold the card properly, Battery life that decreased veeeeery quickly, sometimes it froze for no reason, while on charge and activity you could basicaly grill a steak on the back from how hot it gets, the back battery shell is basically made of Play-Do. I basically hoped for a long time to have a reason to change my phone, I finally had it. Apparently, this was a terrible model for ASUS as a lot of people had pretty much all the same issues as mine.

My experience with this phone is less than 6 months. I use this phone only on WiFi as a second phone for browsing and music. It has a very good and fast performance but it's main problem is battery life. Battery drain indeed fast because of the strong processor and heating. It's lollipop version which I could not update and my zenui didn't update at all. Generally it can be only a good phone for browsing as a phablet nothing more.

RossDorn

Have this phone for a month now, and I like it very much but.... What I do not like is the so-called support.... I have several questions about the installed software/bloatware and there is simply no way to get any answers to questions about that. It takes a lot of time to get all the numbers they want and when I put them in, I am told it does not exist! I check again, type it in and again the same nonsense... the number is definately correct! When I put ín: place of residence, its Tokyo right now, and what happens, the language changes to japanese! Does any of you speak japanese?. So why should I? Is there a place other than ASUS where I can get Info about the phone? THere is ASUS Cover, ASUSServices, ASUS Support,ASUS System webview, ASUS Zen UI, ASUS Zen UI Sevices, ZEN Choice, ZEN Circle a.s.o. a.s.o. Where can I find info what that all is, and why I should keep it? I have disabled notifications, why do I still get constant notifications that I should update Google Play? and Google Store? What is Zen Choie, what do I need it for? What is then ZenUI launcher? Do I need it? Can I delete it? Thanks, give me a hint WHERE to ask, so I actually get an answer to the question I am asking....

Had this phone since it was first available in a 64GB version. I droped it in water and the system board was replaced. That was over three years ago and it has been a good phone for the price and the features. It does have some heating problems and occasionally the screen freezes but can be unfrozen just by pressing the power button off and on. The glass is still scratch free and it charges with a quick charger in an hour. Would like to have had a removable battery but it has provided lots of functionality for a low cost. Perfect pictures every time. I put a 64GB memory card and can watch movies, mp3 files and the sound/video are both incredible! Quite happy this phone has lasted for nearly 4 years!

massive thermal issues, phone has burnt plastic smells when under heavy load.

root it to lineage OS :) android 7

Asus

The worst investment I had. After 18 months of normal usage everything slowed down, upon recharging for a few minutes it freezes, can’t do anything with it. At the end it pissed me off so much that I break it into two pieces with my hands. Asus and mobile phones do not work! Never again.

Fadli

I still use this phone. The screen is cracked but impressively it's so smooth even though it's 2 years old since i bought this. But sadly it's stuck in Marshmallow.

Kenny

I still have this phone. The battery is starting to fail. Overall it was a great phone. I'll get another Asus to replace it.

Anonymous

i had bought the phone somewhere around the beginning of 2016, the only real problem i've encountered (even though my screen cracked within 7 months of usage) was the heating up from high stress activity. The phone did well in its intended purpouse for a good chunk of 2 years but the last 3 months of 2018 made the phone virtually inusable, as the screen stopped responding to image change (except for greater gradients of white forcing the loading of a section directly under them;), bottom to the top, section by section giving out a negative image of the last properly loaded visual or just plain black spot; making the typing and breaking of alarms impossible if not for muscle memory. 7/10 - my temporary xperia E3 outlasted it.

I have mine set to double tap the screen. You just double tap to wake it up, and double tap to lock it. Much easier than using the power button.

Mackleless

This is my experience also. Really loved this phone at first. But the GPS has become a real problem, and I am just over a year of use. If it struggles to get GPS or Cell signal for too long, that triggers the reboots. On my commute to work and back there are two spots where the signal drops for long enough to trigger the reboot. The only way to stop those is to put it in airplane mode while travelling. It served me well and was very cheap, but had the phone not had all these issues making it deteriorate I would have still kept it in stead of upgrading. It handled games well and everything. But then at some point it developed what look like burns on the right side of the LCD, I assume from the aerial inside. That happened at about 6 months of use, then eventually after another 6 months there are these burn marks on the left side too. Like a straight yellow line on the LCD on each side. The performance of the phone still seems to be the same as when it was new. But these little deteriorations. The battery is nothing what it used to be. It can drain from 100% to 20% in an hour of use. Then about a month ago, I guess the sim card reader is also mailfunctioning. As it is sitting on my desk right now, every ten minutes, without any use, suddenly it says no sim card in phone. Then it goes away as it finds the sim card again. If you need a decently powered cellphone for a very short time, like in between contracts or something, it could work. As a powerful but temporary phone. But for anything long term, looking at the comments it seems like this phone just doesn't have any endurance.

ghoti

Not a bad phone. I really liked that it includes a memory card slot and dual SIM. But after a hear of use, it started to intermittently drop GPS, so while Location was turned on, it had no idea where it was. Then it dropped GPS entirely and started randomly rebooting ... and battery life has dropped tremendously, and this unit has a non-removable battery (unless you're very adventurous). Given that it's stuck at Android 6, and support has been dropped in LineageOS, I'd suggest looking elsewhere. This has turned into a lemon.

The screen blackout seems to be a common issue for Zenfone 2. I have 2 of these phone in my family, and both of them suffer the exact same screen issue. Luckily, both of them happened within the warranty period, so I had both of them replaced via ASUS service center in Toronto. Their service is quick, I got them both replaced within 3 working days. After replacement, the screen is fine for 2 years now.

After 1 year, the phone started to suddenly blacks out. I tried to turn on and during the boot it blacks out again. Battery replaced and the issue continues. After the first repair service, Asus Center refuses to help me. Worst phone and service ever for me.

My wife & I each have the 2.3GHz intel & 4GB memory.. all works fine with the phablets except 1 issue we cam across. Imo Asus makes a top notch phone but I will give the advice to buy the magnetic cover/case with the circle on the front made for this device. It will allow you to put the phone in sleep mode when the cover is closed. If you don't have that type of case then you will have to use the power button to wake the phone but that button will stop working due to overuse (the actual component). Then you will have to repair the phone, buy a new one or do a pain in the butt trick buy unplugging the battery plug it back in and press 3 front buttons at once to boot it up. Bottom line: If you buy the phone buy the magnetic case that operates the sleep function.

After 3years my problem is some time message not able to display...

ralph

i have been using this phone for 3 years now. problems that i encountered: - after a year, the screen display only shows 1/3 of it, had it repaired. - not compatible with some micro sd cards that i bought. - you can only use SIM 1 for Data/Internet Connection. - it gets very hot when using Data/Internet. - i'm having trouble powering on the phone because the power button (on back case) is NOT properly aligned with the switch within the Phone. I do not recommend buying this one.

Great short term phone, but you will start having problems within 6 months and it will be practically useless in a year unless you know how to fix it yourself

For fast charging use Qualcomm fast chargers. Google it

nyxia

isnt every phone is like that? there's a sensor in the upperleft of the phone that detects when your ear is close to thephone, it will turn ur screen black

getsomemore

Hold Volume Up button and press Start button together for 7-10 seconds (If Volume Up button doesn't work, try Volume Down button with Start). Phone will restart. This happens when phone crashed and needs to reboot in safe mode.

I've been using this phone since 2015. I used to play games a lot when I first bought it. Nowadays I just use it to call my friends and watch youtube videos. It's a good phone but it has a lot of problems. Here is some of them: -SIM card reader had to be repaired at least 5 times. -Gets really hot when playing heavy games like Asphalt 8 or GTA San Andreas -Plastic shell changes color and cracks due to heat -At some point it started turning off while in my pocket. It wouldn't turn on for 4-5 hours so I had to get it repaired again. -Sometimes screen starts flickering but it goes away when I restart the phone. Good sides: The performance is good and the camera is pretty good. It can take great photos in dark places. Would I buy this phone again? No I don't think so. I would probably get a Motorola phone or maybe a Nokia phone. Or maybe a second hand Google Pixel.

the phone is preety decent for money but not so good..mine has problem with sim card reader and charging issue...once is needing update the phone it become useless after a while

I Bought a new model phone from Asus Zenfone 2 ZE551M & when i try to switch on the phone it was not getting on. kindly provide guidlines immediately.

TheSixer's

in my opinion, This phone has many features, unique ones really. the battery is kind of shitty, but charge really fast (60% in less than 30 mins), the camera is also decent, not good, not bad though.. the performance is fascinating I think, although it heats up pretty fast when losing signals or playing games (PUBG, Asphalt 8). Overall, this is a nice phone, I've been using it for like 2 years, no problem occurs to me..

Kwabena1910

I have issues with screen flickering. I tried to reset (BIOS way) but I couldn't. Any help??

Eko

The phone has lasted over 3 years without screen broken or anything big, the battery still lasts but better to swap it. Phone lasts but very expensive as well.

monuincollege

I am using this phone for close to 3 years now. A powerful performance device with worst build quality, and poor screen. It has never lagged, got hung a few times due to network(data) unavailability. It heats up real quick if you are playing online or heavy offline games. After 2 years Battery performance goes down significantly low. ASUS has already stopped providing updates for this model. There is Lineage OS available for this model. I would recommend using that for better life of the phone. The Build Quality is worst though. The Screen is not as good as expected, and Camera does not seem to perform well under low light conditions.

ira

can u give me the link update

Shlomo

Great phone ! Highly recommend, based on my own experience. Had it for three years now, and it has never failed me. The only thing I would change is the plastic body - my next phone will definitely be an ASUS , with a metal shell.

Lou

Lasted 2 years with me. It has a great performance for its price but the durability of its part is questionable. 1st, the front cam stopped working, 2nd the power button plastic chipped off, and 3rd, the charger doesn't charge the phone properly.

Marky

I've tried my friend's Samsung S7 charger and it charged really fast compared to my generic charger that I bought from a local store

Doug

Do not recommend. After 1 year it stopped working. The phone turns itself off in out of the blue. Low durability for its price. However it has a great performance in its processor, depending on what you use the phone for.

Yeng

What do you think is the best and fast charger for zenfone.

toao

I had mine for over 2 years. No problems at all. Great cell phone for a very reasonable. Depending on the use, battery can last up to 3 days which is a lot more than many other (More expensive) phones. Unlike many others, it has dual SIM and a dedicated memory card slot (Which means that you can use 2 different lines AND a microSD at the same time. Many will share the slot between second line and memory card). Android customizations are great (Unlike LG for example). It includes many useful proprietary Apps. I'd choose this phone over my company-supplied LG G5 (Unusable without a Drawer-App) every time. I spilled water on it (Several times actually) and never had any problem. Complains about it are ridiculous. If you can't keep your cell phone out of the toiled, the problem is not the cell phone...

I have my Zenfone 2 since february 2016, and it's still working as charm... Don't blame ASUS or Zenfone 2 for your particular problem...

AnonD-757678

A decent phone for the price. Battery will last all day if you are not a rabid user. Volume button placement was annoying. Not water replant, at all. Baby slobbered a bit on the phone & it started being wonky. Decent as a teens phone or back up since its now 3 years old.

nnnn

Never never buy it. My zenfon2 was broken. I could not get it repaired even by paying. Mainboard is very bad

Whistle

You can do that...just go to Asus office website and you'll have a list of all firmwares for Asus Zenfone 2 ze551ml...there you'll find a download link..but the process is a bit complicated because you'll have to connect to a PC...search on YouTube..many vids are there!

JPCASP

A very good phone for the price, volume control a little awkward.

AnonD-748623

you got proximity sensor problem, if you still have warranty, you can take it to service center for replacing the proximity or they can replace with new mainboard.

AnonD-748623

Most problem in Zen2 was ghost touch, if you still have warranty, you can claim for repair.

That's how proximity sensor works. When you put the phone next to your ears, screen automatically goes black. But after you take away from your ears back, it will turned on back. But if it doesn't, your proximity sensor is the problem.

I won't buy any asus phone anymore. At first I like it, although it's a bit heavy, but at least it's running perfectly. Well, after a year when my warranty is expired, the ghost touch giving me headache everyday. Once, I made a phone call and this phone hit the end call by its own. The phone become so slow and battery life is so bad. OMG. Yet I still feel lucky, at least my asus survived for more than a year, so I can save money to buy a real phone. My friend's only survived 3 months before it became so slow and made him crazy.

Mulyo

It is not the best ever, but reliable one, and cheap one also. I found it smart, with FHD display, bright and clear, it is interesting feature. The camera is pretty good in his class. But the sound is bad point, not dts or dolby pleasant. With 4gb ram , if you may make same some root move, this gadget is awesome thing. Bloatware is minimum rather than other product. it is true the battery drains fast, no wonder with display quality and good ratio density colour up to 401 ppi. If you want to buy entry level phone compareable with nowadays technology phone, you'll find this gadget no shame, especially if you manage this phone in use time about 2 years using. Not a gamer phone dedicated, but, nonetheless you'll find amusement with it in medium expectation.

Camera got worser and worser as they getting older. I don't know but first time when I tried the camera when early bought it, it was pretty acceptable but now, from Lollipop to Marshmallow and now my phone is 1 year old on December 2017, camera is the worst I have ever used, camera quality is very bad though takes on daylight.

I agree with you 100% I don't recommend zenfone 2, The screen ghost is driving me crazy. it also freezes frequently.

AnonD-730605

Yep. Better stick which its original version Android and user interface to avoid your phone act abnormally. I own 2 Zenfone 2 and try update the second one. And I found that after updating, the phone is not as fun as the original version. Just update the 3rd party app like WhatsApp, Installed games or YouTube only. Many people think I'm stupid because buying multiple of this phone but I'm happy because now I have lots of knowledge and experience in smartphone world

AnonD-730605

The phone is pretty reliable even its not perfect. If you look at the spec, It is the 1st smartphone with 4 gb of ram and the ram management is very good. It also provide a lot of storage and even give us option to expand it with micro sd card slot in dedicated position without sacrificing dual sim abilities. I also own samsung note FE this year in 2018 but I love more on Zenfone 2 user interface which is much user friendly.Besides the audio quality with earpiece is much more kicking with ZenFone 2. The downside of Zenfone 2 are the camera is not too good, micro sd card cannot pulled out, the speaker is awfull, and the sim sometimes disable temporarily.

I had a truma with all asus phone because of this. I have Asus zenfone 2 (4GB RAM 64GB storage) After 1 month of purchase the touch screen got flicker. I send it to asus and was replaced; it was still on warranty. It took them 3 weeks to give my phone back. Then after 3 months SIM slot 1 not detecting. This is the only SIM slot with LTE. Again, it was replaced by Asus. This time the lead time was 4 weeks. I purchased Oneplus phone as a "supposed" temporary replacement. I can't wait 1 month not having a phone to use. I did not use the ASUS phone since then. I'm a tech guy. Everytime someone asks me if Asus Phone is good. I just told them what happened. And this Asus phone did not last a year. I regret buying. To all reading this.. AVOID this phone! Search google! there are a lot of people disappointed with this.

how to update marshmallow to nougat manually?

matraxa

This is the worst phone I have ever had, and I thought my previous one was bad. I have had it for 2 years and I constantly had problems with the screen flickering. Then a month after the expiration of my warranty my phone started restarting itself, constantly thinking i was randomly touching the screen like a lunatic and I decided to change to Lineage OS because I thought that was a software problem. After I changed my phone with Lineage OS my speaker started to sound very crappy and I bought another one and changed it. Well I finally thought everything was OK, that it was finally back to how it used to be, but no it decided that it wont detect my front camera AT ALL. Oh and I forgot the mention the screen still flickers, the touch is still thinking I am clicking when I am not, and phone hasn't stopped restarting (oh and one more thing it even says that I'm not using a supported power brick and cable when I am using the ones that came in the box). I have not been so mad at any phone until now, it really makes me want to throw it from the window from my apartment (I live at the 7th floor so it would look so beautiful to see how it breaks). And don't get me started on the "frequent" and "good" updates that ASUS had released for this phone. Instead of fixing some things they bring more bugs to their OS, like bluetooth randomly and even had the nerves to put even more bloatware into the OS. ASUS, please, do not make any more phones. 1/10.

after 2 and a half years of using this phone: - did pretty decent on its first year - battery life is always poor, 3 hrs of gaming and kaput, or 3 hrs driving with H+ and GPS, kaput - game performance quite laggy on higher end games - touchscreen starting to fail me, has random presses already not a recommended buy!

Negatives: Useless phone. Doesn't detect 2nd SIM often. Battery drains fast. No VoLTE support. No more system upgrade. Speaker volume is very low. Always it hangs. Tired now from ASUS products. Positives: 4gb ram, super fast processor. 5.5 good display, good GPU. Good rear camera. Overall don't buy asus phones.

AnonD-681860

If you want to upgrade to Marshmallow, here's direct link: INSTRUCTIONS: 1. To update your device, copy the firmware zip file to your internal storage. (DO NOT extract the file) 2. Reboot and/or wait for the system update notification to appear 3. Make sure that your battery life is above 80%, click the update notification and then update your phone.

It's 2 years to the date that I bought my Zenfone 2 ZE551ML. The first year was fine but I do agree that the phone's display is drastically reduced when outdoors. After the first year, that's when everything started to happen. The phone would heat up where you could use it to iron your clothes. Screen would flicker. Charging became an issue as even the charger provided by ASUS did not work. Now, the phone is my desk drawer because despite having it plugged in for 12 hours, it still wouldn't want to turn on.

My husband and myself both bought the same phone and his went at a year and a half and now mine at just under 2 years is facing the same mind of it own ghost screen and the bottom of our phones has a inch(his was half the screen) where it's flickering and the screen is messed up. There are times where I can't even use the phone because it is taken over. No rhyme or reason when it happens, then it does it's dance and back to normal minus the screen at the bottom. Zenfone2 551 Asus_Z00AD

I have that issue and didn't replace it.

Its a great phone. Best money can buy. The battery is great when upgrade to 6.1.1.

Sad Costumer

It's been a year now and I regret buying this phone. The battery is a joke, the intel processor is not compatible with the OS so it drains the battery too fast. I have to recharge this damn phone at least three times a day, and I don't even play games, just read a lot. The brightness of the screen is so bad it's impossible to use this phone in the outside during daytime, it always feels like you should be able to make it more bright. Now my phone is actually shutting off itself and I've found many people with the same problem. Apparently this phone also has a lame motherboard. Never buying an ASUS product again.

Any one facing ghost touch issues after replacing touch screen in your Zenfone 2?

The SIM card slot is a problem. The spring loaded locking mechanism stops making reliable contact with the SIM card. Switched to slot 2 and the same thing started to happen after 2- 3 months. Whats worse is the SIM card itself became corrupt after constant mis contacting from the SIM holder. The design of the SIM card holder needs to be improved.

Does anyone else's phone also not charge normally with other chargers except the fast charger provided by asus, takes an entire night to charge to 100% which takes only about 2 hours with my asus charger? Also should I manually download and update the phone to marshmallow/nougat(if available) or will it cause any problems considering I haven't received an auto update from them.

Too much bloodware!!

I still using this phone for almost 2 years now, but my first year using this phone the touch sensor malfunctioned and i need to bring it to customer service in BGC to replace, it was replaced but after a month i still have the same problem with addition of it lags alot. If you buy mid range phones you need to chenge after 2 year its my own assessment just to keep in touch with the technology.

AnonD-710921

In all likelihood this was a problem with the touchscreen. Replace it and you're good to go, maybe for years. This type of issue can happen with any phone.

AnonD-498074

guys, keep the OS updated regularly. this should solve some of your problems. My Zenfone 2 still performing well.

randaman

I had this phone for sometime now and i must say it's great. In 2017 this phone is still pretty snappy. Call quality is good, sound is good and it doesn't lag with games. The only things that are cons are the battery life, and video camera. All in all for a 2015 phone this is a great budget phone that is still holding its own in 2017.

Johnwick

Stupid phone! Only had it for 6 months last 2016 until the GHOSTTOUCH issue appeared. Useless!!! Will never buy an Asus again.

Carls Johnson

Worst f&cking phone i ever had. I've used it for 2 year and it has ghost touch, battery problem, and many more. I see lag too when gaming (NBA LIVE) i must buy a china phone not a taiwan phone

Great phone,, i test it on the water, and nothings happen, it works properly,. I love it

Regret to buy this phone. Ghost touch n battery problem..

This is my last day using the zf2. I love it. But the microUSB port starts to suck, I must change it. The roundness of the back is something I will miss since it fits perfectly with the hand.

goinup

This is one of the best phones I've ever had. No lagging whatsoever, good battery. It only has one huge problem - the SIM card slot. I already replaced it twice within 1 year and it got f****d again. Hopefully newer versions of Asus phones have this issue covered...

oddie7

Yes, really good phone. Used it since early released and it good phone. But I regret replacing it with my Xperia M5, just using about 4 months and it lags like hell. And getting back using it until now it's almost perfect, just not good at gaming, but it's fast on opening apps and for daily usage.

AnonD-286202

The ASUS Zenfone 2 is one of the best phones I've ever had. Excellent pix & video quality, great battery life, great reception, the 4GB RAM is great and very fast, and the 64GB internal memory is all I really need, but I still use a SD card to store my pix and videos on. I bought the phone used and had to replace the SIM/SD card tray, but that was only a few dollars and 1/2 an hours time. (not reading the first SIM card consistently). I prefer this phone over the later ASUS Zenfones because I have a dedicated SD card slot, and I can still use 2 SIM cards, which is the main advantage to me with this type of phone. The later versions require the SD card to use the 2nd SIM slot, which kinda defeats the idea of a dual SIM phone. I recommend this phone to anyone who likes great pix and videos, and a sturdy trustworthy cell phone that meets everyday needs.

Used this phone since release and I have to say it's definitely a decent product for the price. I never had glitches with this phone despite what some have mentioned. Have changed from this to the Zenfone4 recently. A good upgrade

Everything is good but After 1 year, my phone has ghost touch, and I regret of buying this phone.

Do not buy this rubbish phone. This is a trap. ASUS you own me your explanation. The LCD is the worse part of this phone. Flickering, glitching, all the worse thing that you can imagine for an LCD are here. Thanks for your tech hole ASUS.. next time, make sure that your research's budget is bigger than your marketing budget.

I bought this mobile from Jumbo electronic Litex offer, really I m very sad about this , because 3000 MaH battery , even 1 hour also not standing this , the sales girl was by heart how to sell , they never learn , what is the drawbacks , But I am using last 2 years apple iPhone, its my pride , a wonderful in the world

Don't buy this phone. Terrible ghost touch problem will occur after 8 months of using. Terrible product from Asus. Almost most of the user facing the same issue. You guys can check in asus website. Even Asus doesn't have answer for the problem by simply ask to replace the LCD. Worst phone ever...

Luita

Have been using it since 2013. I am a bad user, always dropped my phone everywhere, on road, on table, on floor, etc. But this phone still function greatly until 5 months ago which is caused due I dropped it from 2nd floor. Had to fix the screen and speaker, and it works properly again,until now i had to fix the charger port. Overall, I really love this phone, great quality and endurance, great speaker, nice screen, fast performing, fast charging. The only one weakness is it was too heavy, so I always dropped it since my hands are pretty small.

This is actually a nice phone. But i am a student .i have lot of things browse and use mostly common social media about 10 hours a day .but the phone still works fast and have no hanging problem .but the software has crashed many times . The battery back up is so poor i have writed this content using 2 % of charge with no background apps and at very low screen brightness i am very angry to go long trips with this phone . Cause this phone need a charger all day .after full charging i will unplug the phone and left for free until i came back .this phone seems cool outside when not running after the class the battery will 60 percentage or less i hate this phone

Worst Smart phone i have ever used. Got lots of troubles within a year namely software, Sim not detected, Charging slot problem and got repaired coz of warranty. Now after the warranty is over i am having a issue of sim card not detected i.e sim gets disconnected automatically. his phone got a heap of network issue. Network gets disconnected in between a call. I am afraid to give an interview call by this phone. Now the mic 1 stopped working. This phone is a usless shit. Its a crap. Still now havent got any Volte update. This is a serious shit.I also got a asus earphone with warenty of 6 months and it stopped working right after 6 months and 8 days. This is an honest review so whoever planning to buy this phone or any of asus product. Stay away.....

Crono

Have been using this phone since September 2015 and it still runs the same as on the first day! Very satisfied with it, it's still a good phone to get even in 2017! Interface is awesome, it runs butter smooth, be it apps or games, the phone camera is good for taking pictures during daytime (I don't take pictures during the night anyway), the 32 GB of RAM (25 GB available for use) are more than enough for apps, games, pictures and other type of files.

just got 1, its not powering on.

I have used this phone since the release date, here is my opinion the battery is strong enough to hold up to one day and never lose it's capacity over time, charging it every night before going to bed and it's fine until now, camera is brilliant with although the video isn't, plus the vibration sounded bad. and when it comes to performance, I would like to say good job for intel, this phone doesn't lag after a year usage with its bloated zenUI, still feel smooth, and the performance improves a lot after I installed Nougat with LineageOS buil, while other midrangers will lag in several month, this phone won't. maybe I'll stick to this phone if there's custom oreo build available,

GiLNaT

I got this cell phone in late 2016, it came with Lollipop, I updated it to Marshmallow, but I did not keep that, I currently have it with Nougat with the Lineage distribution and I look forward to updating it to Oreo. But not everything was honey on flakes, came with a problem with the battery, in ASUS could not help me or the process was being very long with the tests without meaning they asked me to do, I ended up buying a new battery and I changed it myself . Is a good cell phone and that is the 2GB version of RAM at 1.83 GHz. It was not so easy to unlock the bootloader and make it root, but once made is just like other cell phones to install ROM's since recovery. The 3000 mAh battery lasts depending on the use they give you. The screen does not have the desired brightness, but with the correct settings it plays videos in 4K. I would buy it again.

Tomilung

I used this phone almost 2 years. No need to argue. Satisfied. Truly smartphone.

AnonD-695429

Bought it on in July 2016, there was a sale on B&H. It was great when such cheap phone had so great power, but it became hot even after 30-minutes of casual gaming. And after a year the screen stopped rendering the bottom side, then both SIM died and after that even speaker stopped working. This is motherboard issue which costs 120$. Very bad!

Bita

I bought it 2years ago & I love it so much but this week I had a problem with its LCD!The colors on the bottom of the cellphone are mixed up. I'll have to work half an hour so that the touch will work again as normal.I dont want to change it but I have to do it :(

MitjaSLO

Same with me.

MitjaSLO

A total garbage of a phone, very sensitive touchscreen and it touches by itself and sometimes doesn't work, no native app for videocall, the back button is not backlit and it can also be bendable easily so you must take good care of it and the plastic at the back brokes near the audio jack and it slides down making whole thin plastic USELESS. It still works but touchscreen and weak quality is a NO NO for me, I will buy Nokia 8 new one instead.

Asus zenfone 2 is good. I like the specs and its speed for games is awesome :) I only had a software problem that sim 2 slot is not detected and have it repaired in Asus service center for free due to warranty. It works fine now. My only problem now is my charger, the cable is easy to lose and it takes me a day to charge my phone to 100%.

Anonymous

Today marks the day when my Asus Zenfone 2 dies. SIM 1 is no longer detecting my SIM card, meaning it is useless. Been using it since September 2015. Sent it for repair for quite sometime. My secondary slot for SIM only recognizes the sim inserted for ~5 mins before the signal disappears. I believe most users are facing SIM issues. Charger adapter was broken after several months of use, got it replaced with a new one, and went broken again after few more months (no more replacement since the warranty is over). Battery life is not that long. The screen always gets unlocked automatically when the phone is in my pocket. No more ASUS phones for me. I used their tab before this and it was disappointing as well.

Ikhwan 79

Ghost touch happen every time, always...especially when oppening web browser, playg game etc.

I bought this phone a year back and i guess this work works fine till the warranty date. I have a serious problem with this phone been changing the ASUS cable and the charging adaptor right from the Asus service centre (Hyderabad) and still my phone has a crazy CHARGING PROBLEM. Very poor service they don't give a damn about checking my phone's hardware/software. I reset my phone multiple times yet it shows unsupported power adaptor and sometimes it just go dead in the middle. Never ever going to buy ASUS again.

2 days ago suddenly the front camera stopped working, couldn't find the button in the camera app, couldn't do video calls on Whatsapp, couldn't even use the Asus mirror app. Anyone experiencing something similar? Is it time to get a new phone? (If yes please recommend an Android to me! Thanks:))

I love my Zenfone 2 I've had some issues from the one for the guys was talking about mostly because I didn't know how to operate it and turned all the apps off and all the things that I didn't want running. Once I sorted the phone out it is amazing 4 gig ram 2.3 processor fantastic love it my second one I will buy another one. I also had an SD card issue it was corrupted by from a good supplier which I did afterwards that is some chips cab son's been unreal both sides has been perfect

I bought this phone on September 2015. Lately I've experienced a random overheat and battery drains way too fast, it only last like less than 4hrs with average usage (surfing internet, facebooking) and sometimes it couldn't detect my sim card which scares me the most. The camera are excellent but videos are horrible. Very choosy when it comes to USB for charging. But overall, it still working good.

Bought this phone last year for me and my brother. We liked it at first time. Really loved it. Good performance for first 2 months. After that, everything is so slow and unable to read sim card, ghost touch, blurry camera, battery problems, etc. After I read all the comments in here, now I know that it's the phone itself. Good for you whose phones still good. But for us whose phones got problems, won't buy ASUS anymore.

I got this phone in 2015, july, 2/16. This phone makes a great headache.. It has some issues, first the unexpected removal of SD card, which actually is a software issue (mine got repaired in 2016 software update), and until today I never have android upgrade (mine still run with lollipop).. Recently, my phone start having sim card undetected issue, which is purely hardware issue (my sim card is working fine in another phone, thank you) and I got tired of this phone 'attitude' just want to throw this phone and got new one instead. Battery is not good, but I don't have any expectation with that.

bought this in 2015.. has unexpected removal of SD card issues, and then it got fixed in 2016 software update.. my phone hasn't got any android update (still run with lollipop), battery is no good but it's expected.. it got worse now because of sim card not detected issue (what a phone without sim card, a stone?).. I'm sure the problem is purely hardware because my sim card work completely fine with another smartphone.. got tired of this zf2 and considering to buy a new phone

I bought my zenfone 2 january 2016. I was putting my SIM and SD Card. While opening the back case cover using my finger naila, it cracked. The crack is now about 3-4 mm. It's very thin and there is flexing. It should not break in the normal opening of the back cover. Now I'm afraid to upgrade my microSD card.

AnonD-688766

Was very excited to buy this phone a year ago or so. It looked good, specs seemed fantastic and all. And for a while it worked great. Only complain was the case design: a bit to thin to hold it properly with one hand, although it looked cool, a silicone case fixed the grip problems... After only a couple months, the screen shattered while in my pocket, probably keys. This things happen. At least it still worked. A couple of months later, screen turned black and phone stoped working, right in the middle of a panoramic picture session at the beach. To much heat perhaps? Got it repaired, new original screen installed and some other hardware problem. Official Asus Service in Spain sucked, so I did it in a not official but professional shop. New screen worked perfect, Phone was as new! 2 months later, screen starts to work oddly, not recognizing touch properly. Couple of weeks later, smashed the screen again on my pocket. Gorilla glass my ass! So after 1.5 years of buying, I'd say is is quite fragile, and kinda lemmony. I'm in a hurry to get another phone. It looks great, seems like it could have been a great phone, but it sucked ass big time, in my experience. A shame for Asus, an otheriwse great company.

I have had this phone now for just over a year, and it works fine in every regard. Photos are great; video is superb, and the cost was reasonable. Frankly, I consider it a beautiful phone and am totally pleased with it. The ONLY complaint is that it comes with loads of useless bloatware which you cannot remove.

I have absolutely no problem with this phone. I have been using it for a long time, more than a year now and its superb. Best is the 64 gb it gives, so no need of getting memory card.

I'm using this phone for 6 months and no problem at all. I wonder how can people only using this phone for a few weeks and it already having problem. This phone has a decent graphic quality, fast processing speed, and quite accurate gps functions. Zenfone 2 actually a great phone for a cheap price.

The best thing about this phone is that it makes angry all the people that bought phones 3 times as expensive but with lower specs

I bought this phone thinking it would last for a long time but unfortunately it died after 3 weeks of use. The screen went black and the LED light did not turn on. I even sent the phone for repair while the warranty was still valid but they told me i had to pay over 200$CAD to repair the motherboard...since it was not included in the warranty... Just do yourself a favor and don't buy this phone. It's a waste of money and time!

Guest

ASUS - Please consider focusing and improve on your PC's only, so at least people will not stop buying it! And please do everyone a favor - leave the phone industry, because you just cant do it! Just sharing my own experience with Zenphone 2 for the past year of usage. That's it.

The most idiotic phone ever used. Wasted my money. Don't ever consider buying this cr*p!

using this since 2015 the first time ze551 were introduced, it performs perfectly as a mid-ranger, the camera is brilliant with its manual control and color contrast, although recording from this device and a lot details were missing in the camera result. performance? the stock rom (5.0) is bloated and runs like a snail, but it got fixed after the 6.0 update because most bloatware removed, flashing custom 7.1 rom will give you a boost and it is more faster, have no performance drop issues until now and currently still using it as a "primary phone" .

AnonD-683769

I had the same issue few months ago, after I connected the phone to laptop. It seems to be due to the fact that laptop hasn't the driver for the Intel processor of the phone, and the phone blocks itself to "protect". Try to open the phone, and disconnect the wire from battery to mainboard. It worked for me. Good luck. You can find tutorials on youtube.

Momma's boy

Phone kinda broke. Bought it for my mom. Phone started clicking itself and the screen is blurry. Bought it in 2016 November. Broke today July 2017. It's not even a year yet. Great specs, but ASUS DOES NOT LAST LONG.

Youtch123

Wow, chill out dude. That person only said that and you accused him/her for being a flat out lie? Seeing a lot of negative comments, I don't think that person is a liar. I agree with you, nothing is perfect. But seeing these comments and ppl who defended ASUS makes me realize this phone makes everybody crazy. I'm not using ASUS myself, just searching for cheap phone and saw a lot of negative comments. Won't buy ASUS since there's a lot of negative comments. Although Samsung made mistake with note 7, they pulled that item out of the market and they apologized to their customers. I don't know about other brands though.

AnonD-125572

Not even 2 years in mine had already died. Common problem too. Can't charge (indicator off) and can't turn on. Remained dead and it vibrates twice every (about a minute) until the battery drains completely. Search on YouTube for this problem and you will see a lot of fix suggestions (that are not necessarily successful). If you are lucky and your warranty is still active you can get it repaired otherwise if you're like me with a little over a year usage you will be dumbfounded and not be able to do anything except sacrificing almost half of its initial value to repair if (if you're willing, even the repair shop told me it's a waste of money). If you are very lucky the solution to the can't charge problem is as easy as removing the backcover, unscrew everything at the back, detach the battery pin and reattach (you wish you're this lucky obviously it didn't work for me). If you look at the market price now, the price plummeted to a third of its initial selling price. Tip: Next time buying a phone, buy two phones (1 for work 1 for leisure) and always research on the phone's common problems. Or get extended warranties.

AnonD-682862

This is a flat out lie and you know it. EVERY phone company has phone issues. Hello. Remember the exploding Samsungs like year? It's only the negative reviews that stick out with people and with companies like Asus who are trying to make a bigger impact in the smartphone market it can hurt them (while giants Samsung and Apple have many if not more problems and you barely hear a thing from people like you but will flood Asus, OnePlus and Axon videos/articles with negative comments)

Been using the phone for awhile and eventually got that ghost touch... a few months later I bust the screen while trying to not drop it in a camp fire. Ended up replacing the screen myself for about 28 usd. Still works fine, still is a beast. You hear all those people complain about ghost touch, just replace the screen.... It's not that hard...

I bought this phone on July 2015 and used it until July 2017, for about $300. Lets say its a okay phone. The first time i'm did system update, my phone restart every minutes, because we know go to CS never went well, so i try reboot my phone, and luckily it solve the problem (so i never update my phone for almost 1.8 years, and rarely shut down or restart my phone because somehow it trigger "the restart problem", until recently i did the system update, and "the restart problem" did not happen, so lets say i'm paranoid, but yeah,,,) The performance was ok, even though have 4 RAM, i did not notice the difference. it's still lag and sometimes freeze when i playing game. My friends complain about the heat when charge and play game, it happens to me too, but i still can tolerate that. From my phone, the best thing is the picture, i satisfied with the quality, even until 2 years (i just use it in moderation, and for personal used only) Lately my touch screen not responsive, and eventually in the middle of my screen about 2 cm gap not responsive at all. That's the end of my journey with my ASUS, LOL,,, i hope we can last much longer but i'll pass ASUS phone for now

I've been using this ZE551ML phone for more than 2 years already ( I bought it when it was launched) and had to say its still good. The only issue I had with it are the battery life and ghost touch, it happen when the phone gets hot, it's not intermittent but it's annoying when it happened. Apart from it, it is still a decent phone with LTE, NFC and more than other phone without one. The battery drains fast because it use intel atom soc (which is a cheap powerhouse soc back then) which now asus decide to drop it and use snapdragon instead.

yoshua007

this comments based in kid's lie

Harens

Sometimes it bothers me to read comment from adults filled with lies! How can someone in their right mind say ASUS ZENFONE2 ZE551ML is suck? That's a lie! I have used Samsung phones and have used over 10 Sony phone(am a did hard Sony user) not until a deal introduced ASUS to me. 8months now no issue, it's works well. Sometimes when people say cracked screen, home key damage etc I sense an irresponsible use of mobile devices by this people~even if the casing is made of Alloy ore an irresponsible user will always find a way to damage it and blame someone. This phone is among the best 2 phones I have ever used.

It is that bad. Imagine this: having a video swipe left and right when you are watching video and while you are looking at instagram, it swipe up and down by itself. It really pissing me off. And because of this ghost touch, the battery drains so fast yet the battery is already bad to begin with. When mine already 6 months, the home button, the return button, and the screen shot button broken. Now, I'm using assistive touch app. The camera is bad too, very blurry. The casing easy broken. I was changing my sim cards and plugging earphone and it's cracking already. Really not recommended Asus phone.

I've bought this phone 2 years ago, I'm still using it and it's still going strong! Good performance, decent battery life, big amount of RAM, still gets updates from Asus even after more than 2 years since the phone was released. I only had a battery drain problem once, took the phone to the Asus service in my area and they replaced the battery and since then it's been running as intended again. Running it on Marshmallow. A phone that is still a good choice, even in 2017!

Bought this phone September 2015 and been using it until 3 weeks ago. Overall, it was a great phone. Three weeks ago, it won't charge then eventually it won't power on. At first I thought maybe the charger was the problem. Tried charging it via PC/other chargers. Took it to an Asus service center. They said they were going to diagnose the phone first to find out what the problem is. JFC, it took them a week (and they almost lost the phone). So they tried replacing the battery and the LCD. It powered on for a while. They said the problem was "probably" the mainboard. (I don't really know much about that stuff so anyway...) I didn't want to get a new phone yet so I asked how much it would cost for the repair. Costs add up to 6000PHP (around 120USD). Lol. I'd rather buy a new phone with that money. Asus service center sucks. Lolololol.

I actually samsung user, before move on to this Zenfone 2, I'm on Samsung Galaxy S4, I like samsung S4 but just because of battery draining fast most of samsung model, I change my phone to zenfone 2.. so far as I'm using it quite nice until this lately I noticed that quality of picture captured by this zenfone 2 camera can't defeat the samsung S4 camera quality, I just love the display bigger than S4 and the battery more saver than S4.. after latest update by asus before some minor bug dumping my phone.. like drop calling, and some of built-in apps not running as usually.. it going to not responding.. it bother me...

AnonD-476113

I owned this phone from summer 2015 to spring 2017. It faced numerous hardware problems, including both SIM card readers failing in August 2016. I hung on as long as I could, but other problems came up (constant overheating, poor camera issues, constant app incompatibilities due to the x86 processor, and an extremely buggy Marshmallow update that broke compatibility with many other apps). Customer service was useless throughout, and the Marshmallow update came extremely late, long after it was promised. When confronted, they did not accept their error, instead editing their original comment on their forums promising the update deadline. Their Marshmallow update was a buggy beta at best, and after that ASUS abandoned the ZenFone 2 for the most part (the phone only got one major Android update). I happily replaced my ZenFone 2 and will never buy a mobile phone from ASUS again.

Gentleman

Never buy asus phone you will regret within 1 month and the customer service is the worst one. They do not know if your phone is under warranty or not. They tell you to send your phone to service center and later ask for repair money citing your phone is not under warranty. Asus phone is the worst phone you will ever buy.

Don't buy this phone guys.. useless camera.. battery sucks.. heat up while playing games... ghost touches... calling screen issues.. no volte... no firmare version update(some but not big one) cant play heavy games as well.... i bought this phone 1and 1/2 year ago in 21000 Rs now it costs 13000..wtf... i use this phone only for usb tethering... lol

Nerramus

I have purchased it new 2 years ago, with Android 5.0 I have no problems at all, battery life is great, phone is fast and smooth, do not want to get rid of it.

Ron

I purchased this phone in 2016. Long story short. Till this day 6/23/2017, this is the most expensive phone I have ever purchased and by far the worst. Most importantly it does not hold a charge. It will cut off automatically, during a conversation. It is constantly upgrading apps which consumes more data space. I personally believe, that ASUS should refund any customer, with a complaint, on this phone. I could only imagine how bad the other phones were.....DO NOT PURCHASE ANY ASUS ZENFONES. They are making tons of money for small technology......ASUS, TAKE CARE OF YOUR CUSTOMERS.....THIS IS FRAUD!

Is there VoLte support after update ?

Drashti

I bought the phone in march 2016.... the begging period was very nice and performance was great. The only problem was over heating of phone while charging and when in sunlight. in just a year the camera app started deprecating and then completely stopped working...The motherboard crashed and the cost for a new one was above 14k. This is the worst buy! A phone of 18k can't even function for 1 year. HIGHLY NOT RECOMMENDED.

I called the guy again, but this damn ghost touch won't let me and I really want to smack this stupid phone on the wall! it's even useless than my 5 years old Xperia U which turning 6 next month. And you are right, the cost is more expensive than samsung since you need to repair it and guess what? Once you repair it, the ghost touch is still there. What a joke! I'm stuck with this phone for a while until Samsung or one plus come out.

This phone is bad, really really bad. I have sony Xperia U for 5 years and started to go bad after his 4th year. But with this phone from motherboard company it only lasted for half a year and it started to have battery problem, after that camera suck problem (it becomes so blurry, very blurry!) and if it like wasn't enough for only these two problems, ghost touch appear every single day! it's like his routine to do ghost touch. I'm sick of this phone! 4GB memory is only marketing strategy from asus, 4GB ram runs like 512MB ram, too many asus' useless app, asus launcher is SO, I repeat SO SLOW. I'm done with this phone. It's better you focus making motherboards, ASUS!

"Adaptive fast charging" Fast charge to 70% to avoid hardware damage from overheating ...because ...intel. True on camera and speaker. However, currently i always have 2+ gb ram available. Only down to 1+ gb when i open multiple apps. (I have NEVER seen my Zenfone 2 RAM drop to below 1gb ram after 2 years of use) Here's a tip; Disable most bloatware And like i mentioned several comments down, never use 3rd party app cleaner, asus have their own and it works really good. (imo, most phone 2015 and up always have their own version of device manager app and most works wonder since they're optimised for the device unlike 3rd party app) Update manually to Android 6.0, it helps a lot, i posted a comment about it, just scroll down hehe. Not sure about your problem on WA, might wanna try factory reset my WA works nicely, I can even do quick reply from top pop up notif.

Asus ZF2 ZE551ML I've been using it about almost 2 years, probably 1 year and 9 months Here's that can I summary for this : - Fast Charging only useful until 70%, after that only normal charge until 100% - Usage for few First Month since August 2015 is good except battery issue which every below 50%, you should aware that it will dies itself - All Component is quite durable for charge, headphone jack, and power button - Camera Quality is one of the worst, because you have to focus and less movement to make sure you get a good picture which still blur if you zoom it about 300% above in Computer - There's One way to make your ASUS ZF2 ZE551ML camera get clear picture, by using Third-Party Apps, like CameraMX in my Phone - Speaker is Average, no complaint or appraise about it - Touch-Screen at First, is amazing, after several drop unmistaken or mistaken because stress or else, sometime it didn't respond well - Usually there were ghost touch by press emergency number which usually happening if you put your phone in your jeans pocket - After almost 2 years, there were so many signal trouble, (Bad Receiver, Lost Signal, and Bad Internet Speed in this while my friends by comparison using it in other phones using same carriage) - Build Quality isn't the best, because several dropdown, costing this Face Camera not work which sometime used by my friends and the phones isn't have any respons, but always showing lagging - Asus ZenUI Launcher is taking a lot memory just for a launcher and even it has advertising itself in anyway - No Update just for 5.1.1, not to 6.0.1 yet, so, you can guest how it's works inside this phone - RAM Memory Allocation is bad, available in 4GB in marketing, but reality only shows 3.8GB, and if you not using anything at first moment buy it, you still have 2GB to use, but for now only 1,2GB at fully potential available to use - Because I'm using softcover for the backside of the phone, the plastic is really dirty and to clean it, minimal using alcohol which not beer, but sanitizer - Too Many Build-In Apps which useless, only 15% apps in my phone is useful, the rest is junk - If you turn on Clean Master, it will advert on your Notificiation and usually if isn't between ads or even malware invitation - In several weeks before write this, this phone isn't read the SIM2 so well which really annoying - Browser by ZenUI Build-In isn't work properly again, so like or not, you have to use Google Chrome - While You update your apps, this phone is cannot be used because the laggy costing the apps that you open while update the other apps might be Crash - WhatsApp notification even I turn on, it won't tell you except you have to open WhatsApp everytime you need to communicate with someone - If you turn on your phone quite long without restart or everything, probably the screen wil get affected coz' by GPU cannot load the graphics well, even when you watch video on Youtube - If you want to play game, my best recommendation to play in Airplane Mode, because the Laggy possiblity is minimal than turn on the signal, I've been try play NFS MW 2012 and it works well, you can play it too while not in airplane mode, but after few plays, it will laggy - Cost itself is very depreciate, because when it out in Indonesia, starts at Rp. 4,1 Million, I bought it at Rp. 3,9 Millions, today probably only about Rp. 2 Million. So, after experience this phone, I'm suggesting that you better pick the phones which support quality, software, and less complaint by people. Because, this phone is good at the beginning cycle, but will be useless at the end of the cycle. Thanks for watching these many comments :D Charlico

Just manually update it, its very easy. Besides, its official from ASUS. Choose Android and then Firmware, from there choose the LATEST file according to your device's type/model. READ THE MANUAL PROVIDED ON THAT WEBSITE AND DO NOT DOWNLOAD THE WRONG VERSION, AS IT WILL BRICK YOUR DEVICE. check under Settings > About > Model Number or Software Information

Been using this phone since Sept 2015. Overall experience: it was a great phone. Recently, it started switching off by itself. Like when I try to send a message or open apps like fb, ig, etc. Screen would freeze then it'll turn off. Sometimes it turns off even when it's just on standby! And it would take long to switch on. Drains a lot of battery. Not even using my phone heavily. Plus Asus hasn't released OTA update for marshmallow. I'm planning on buying a new phone because of those.

FYI, I already been there. I live in Taiwan, ASUS is from Taiwan mind you. And the customer service there only said "It's Zenfone 2 biggest flaw". People like you should stop defending ASUS. ASUS is a bad phone company, even Taiwanese regret after buying Zenfone 2. It's only good to use for few months, after that there will be a lot of bugs. I even called to the center call, talking using Chinese and they just "Nothing we can do except changing it again." I won't pay them anything. It's their own fault to make bad phone!

Mine started random shut down now after a year. Last night, I made a phone call, and it shut down by itself, battery = 92%, when I turn it on again, the battery become = 73%. I really want to throw this piece of **** into the ocean. I will not buy anything with ASUS brand again. Good job for making useless garbage, ASUS.

Whatever

All in all it's a good phone, but mobile network connection issue lower its value very very much >: ( Despite good reception, people calling me hear that I'm offline or switched off, or faulty connection, etc. Some friends think that I added them to a blacklist )) You may google it, if you want, there is enough discussions of this problem. And it doesn't depend on your country nor provider. Shamefully Asus doesn't bother with fixing this, which is main factor for avoiding this brand next time.

I bought this phone in May 2015, so I've had it for 2 years. This has been an amazingly great phone, for an amazing price. Like any electronics, sometimes you get a lemon. I've had absolutely no issues with this phone, the battery is still holding a charge for a long time. I use the phone a lot for Internet stuff like Facebook, Instagram, e-mails, map, music and pictures, plus texting. Very little for, you know, talking. Some of the pictures I've taken with this phone were quite fantastic and impressive. The stock Android wasn't great, it was painful to get Marshmallow, but since then it's been an even better phone. I use the Google launcher, not the ZenUI, and that made the whole experience even nicer and smoother. After 2 years, I'm tired of the curved back, I want something slimmer and more stylish. Yes, this is all plastics but you know what, it doesn't feel cheap, and it doesn't break just looking at it... like those with glass backs (ZenFone 3?)...

Do not buy this phone, while it provided a lot of power (as of 2016), it is all plastic. Within months, speaker failed, power button soldered onto mainboard failed. Poor quality.

AnonD-654897

Bought that phone because it has dual sim, large screen, and Asus is a famous company for computer hardware. It's totally wrong. After used for few months, problems issued (1) Phone halted almost everyday, (2) Phone suddenly turn offed. (3) Although it's dual sim, the second sim only has 2g. If you are using AT&T 2g network has been shut down, it's useless. Search on Google, you will found problems (1) and (2) on that phone. Never buy any cell phone from Asus again.

You should go to the asus official central service in ur area or country and ask them to change the lcd or whatever that seems error in there. My dad have a same issue too before. First service only stays for 2 days and the issue came back and then he toss his phone until it went black and send it to the bigger official central service, he tell them to change everything that seems error because he just bought it for 2 months. Now everything's nice and fine

Does anyone own ZE551ML with batch production around Serial Number F8AZFG 00F789 and having issue? Was thinking Asus are dumping problem unit selling at discounted price. The issue of flickering screen: ww.youtube.com/watch?v=Az0c5ucpTmM

Anonymous

Got my US variant (ZE551ML - Z3560/2GB/16GB) for 2 years now. Few months ago a side of my touchscreen was dead so I bought a new screen (20 bucks) and replaced it myself. I also took the official cover and the fast charger which was not included with my model. This a good phone except to the camera (very average) and maybe its weight. The battery is okay (1 to 1.5 days in normal use). The only thing to do to be sure that the battery is correctly calibrated is to complete a wipe cache (with the recovery mode). Last thing to know. Unfortunately, the ZE551ML is no longer really updated by ASUS. It's because this model uses the Intel chipset (which stopped the support and development). So no VoLTE activation and probably no official Android N. Hope that the LineageOS community will release a stable version for us. I'm not really angry against ASUS but I'm a little bit disappointed by the lack of communication.

It's my mistake to buy this phone, this phone is only good for 3-5 months, after that the "sickness" comes what makes it's super annoying is the ghost touch. I'm watching videos and it started to press the next button over and over again by itself. Please ASUS!! show you care about your customer!! Or maybe you should just stick to the motherboards, your motherboards are good

nascomainman

this is the first mobile phone that lasted 2 years with me and i am still using this phone. with a tempered glass protector and a bumper/case its a sturdy phone. the phone is not for heavy gaming like NBA, but is good enough for casual games. After 2 years of service it's now experiencing ghost movements/unresponsive screen where in i need to hit on the on/off button to fix. I guess this is caused by build up on the cache/ram as i rarely switch off or restart my phone (sometimes weeks without switching it off). This phone served me well.

Anon12345

Stop trolling. Seriously though, too many trolls here. If you get clumsy (dropped it, spilled coffee on it, etc) or lend your phone to a young sibling or a young child and it got damaged its not the manufacturer's fault. Besides, I've been using it for almost 2 years and i dropped it from my bed/table/pocket/hand slipped quite often, performance is still unaffected. Also, you might wanna check the genuity of your device, there are some apps that can help you. I don't get paid to say all of this. Im just a fan of an affordable-good/high performing device and a happy customer.

(By 14th April, 2017) I've been using it for 1 yr and 9 months. So far so good, everything is still working really well. (Camera, fast charging, etc) Capable of playing heavy online games like; World of Tanks Blitz, Avabel Online, etc. on high settings and no lag/stutter. Still getting 45-60 FPS on those games even after almost 2 years of usage. (Depends on device heat) Tips for those who complained about battery; 1. Prevent auto start of apps. (i disabled most of mine, not the one where you disable apps though, only the auto start), saves a lot of battery/RAM. 2. When youre not using it (work/class, etc), switch to Power Saving or Super Saving mode. Leaving it on Performance mode drains battery. 3. Disable/uninstall bloatwares and dont use third party "clean up" apps ZE551ML has an excellent mobile manager that is optimised for this device given by ASUS (Again, saves a lot of Batt/RAM)

This phone is a product of shamefulness. After a year using it, my phone almost in the brick of her death. Random ghost touch, battery draining so fast, bad camera, become so slow each day, and many bad things happens with this phone. While my other phone, SONY last longer than her. My SONY survived 2 years and a half before she gets battery problems too. The customer service is freaking bad too. No problem solving after contacted them. Instead of solving this phone problem's ASUS decided to make a new phone. Which I'll never buy again. I think ASUS shouldn't make phone, they focus on making motherboards as it's their specialties. But who am I kidding, ASUS never will hear their customers. Will go with other brand after my ASUS RIP, which probably not too long.

the problem wasn´t asus itself but intel...I believe Asus started on the wrong foot by developing a partnership with Intel from the beguining. They realised that thats why the launched different versions with qualcomm chips and they doing a lot better now.

I am using Asus Zenfone 2 ZE551ML mobile for past 2 years and the mobile performance as well as specification is very good and enough. Camera quality, Software, Specifications, Applications, Performance are very good overall. It is fast charging when we charging mobile in in 30 - 40 min almost 60% - 70% battery charge quickly which is also good thing. Only small concern is when we using mobile the battery charge getting reduce or down soon. If we start from 100% when we use mobile with or without mobile data or WI-Fi almost 12 hrs to 18 hrs go with battery and here also one thing noticed is if the battery charge get reduced below 10% then also we can able to use mobile with net connection up to it will go with 3% or 2% level which is plus point only and it looks or showing good performance mobile. Normally now a days most of the android smartphones when we use more hours with more apps then the battery percent will get reduce we can see and it is accross very mobile. So this mobile is overall very good and happy to use. Thanks.

Crap. Bought it because it has dual sim, the screen size fulfilled my requirements. After used few months and upgraded to Android 6.0 problems come out. Phone halted almost once a day. sometimes more than twice. Has to shut it off and power it on again. Has put screen protector and cover, dropped on the floor accidentally the LCD screen at the bottom edge become dark. Never has these problems on Samsung, Xperia phone I used before. Thought Asus is a famous computer and has good reputation on computer hardware. It totally changed my mind, never buy Asus again.

It's so fast, native multiwindow is incredible, animations and fluidity is just unbelievable, and new features are there!! It's like it has a new phone. Performance is a champ!! Zen UI was so frustrating but now I jave a clean and polished stock UI. I love this phone got it for some cheap bucks and now it's just surprisingly better.

Its the charger. Youll get notification that your phone may get a bit hot bec of the fast charging. If your planning to buy the fast charger I suggest buying it directly from ASUS

I'm still using Lollipop stock rom and the only time I encountered the heat issue is when I play Pokemon Go (data, wifi and gps on) which I read in forums that is normal especially when the phone is having a hard time getting signal (in my country signal reception is so poor) and they say that Intel chips have high heat threshold (I play heavy graphics games like Marvel FF, FF Mobius, etc. and no overheat). Only issue I encountered is mediocre battery life. Installed original tempered glass (not cheap ones) since day one and never encountered ghost touch or any screen issues. My brother in law bought one (same deluxe version) but encountered 3 issues: usb bug in which the phone dies when plugged into pc and you need to remove and reconnect battery (I dissassembled his phone and did the fix), ghost touches but due to poor handling (he just place it in his backpack which he admits he accidentally sits on at work), and bloated battery (he always lets his phone reach 0% charge). Overall one of the best phones I've purchased. Just hoped that when I update it this week to Marshmallow I won't encounter any problems (proximity bug and sensor bugs).

yes ASUS deluxe Is best choice to have a good mobile now. in just two months I purchased two mobile for my family because I am using it. it is very easy to operate and their functions are really amazing. thanks to ASUS

So far i use the 6.0.1 is more good. But if you don't comfort with that you can downgrade to 5.0

AnonD-649972

Good Day Sir! Any bugs/problems in the newest and updated marshmallow rom? Particularly the proximity sensor bug? Is it better to reset data or just update it as is? I'm still stuck in Lollipop because I fear that the Marshmallow rom/update is still unstable. Thanks!

Oh, and the sim slot is easily broken too. Seriously ASUS?

Negative: easily overheat, ghost touch every time it gets too cold (during winter), bad casing (mine is broken in headset place), poor battery life, poor customer service, can't play new games, easily broken buttons, foggy screen Positive: Cheap I don't mind all of those negative sides except the ghost touch! I've fixed it before in ASUS center in Taipei, but it gets the sickness again after only 3 months being repaired and I spent almost 1000NT for it. It's really stupid, I won't spend my money anymore on this phone, I'll go buy a new phone. You've disappointed me ASUS. Overall: very bad phone, bad brand, not recommended it

what make this phone has FAST CHARGING feature? the battery, charger or the Mainboard it self..? coz my phone is cannot fast charging anymore rightnow..

Bought this phone last aug 2015 got the 4gb 64 gb variant, battery life is ok, quite disappointing it cant play NBA 2k16, 2k17. I used to have a problem with the touchscreen not responding once the CPU gets hot, but uninstalling a few apps and switching off the phone when I am asleep solved the problem. So far I am satisfied with the phone. Just waiting for Nokia to release their phone this year.

Hi everyone, i have some issues on my asus zf 2 ZE551ML . Problem is when im calling with someone on a phone ,the sounds is not clear,lil bit noisy . It is because fo software problem or etc? I just bought and use this phone from 1week ago ,thanks

I only saw improvements on it. Performance little bit faster and I realise my battery drains slower than Android L. But it depends on how you used the phone. My battery could last 7h (estimated) on using internet such as WhatsApp, Instagram n others. I played Asphalt 8 and it can last for 1h 20m (estimated). Sorry for any bad english. Hope u understand

Constant Wi-Fi connection problems, barely working Bluetooth, huge battery drain, screen not being legible in the daylight (ambient light sensor not used properly). Really glaring problems, and manufacturer focuses on colorful ui, wallpapers, needless apps (that Google does better) instead of bug fixes and OS updates. Main camera is OK, build quality fine, but software problems are typical for asian manufacturer.

I wonder how you all that had problems with this phone. I already bought this phone from 2015 December until now (Feb 2017) overall is good. Good performance, no big problems even lag.

Until now there is no issue anymore - Don't get fall down. surface edge portions are very vulnerable

Hello Guys, i want clear about this i'm using ZE551ML 4gb RAM Phone working very smooth compare to others like Lenovo/Micromax/Carbon/Lava/Vivo as price it is little bit high as specification but not more per quality. The Intel processor is great but take more battery. After 1.2 year i have to replace the battery. Camera is good but in Low light or Night Performance wise no one can delivery smooth like Intel it my Experience after using various phone have various processors Like Samsung/HTC/MI/OPPo/VIvo/Sony etc. for Games honestly its good but not best but for multi apps no can compare this.

AnonD-115685

So many complaints here @ this phone, I really wonder what you guys are doing with it if it's working as bad as you're complaining. I have mine since August 2015 and it's working great. Smooth as butter, battery life is decent and no problems while gaming. Upgraded it to Marshmallow a few months ago and I only saw improvements to it, battery life stayed the same. A very good phone for its times and it's still quite good even now, in Q1 2017.

For the people who asking Marshmallow Update, download update manually from this site there is no OTA works fine without any problem and performance tweaks. 1.download this file :UL-Z00A-WW-4.21.40.134-user.zip. 2. paste it root directory of internal memory. not in downloads folder. 3. restart ur phone. u will get notification to update. 4. click Update, it will take nearly 20 to 30 mins. it will work without any bugs and u will get a 75mb OTA update for security patch. and install it. thats all marshmallow is done

Not gonna buy any asus phone ever again, since this is my first ever smartphone i thought that this phone is quite cool with it's spec and it's a standard for a smartphone, after i change my phone to other products i just realized how stupid i was, lmao. 4 gb ram doesn't really matter, still slow, not optimized. new phone got 3 gb of ram, smooth like baby's butt. intel proc just worse, well not the worst tho but still it suck. playing multi games with friends, lag, my friend use samsung s4 and it's smooth as heck, really!!!??? at first i thought it was the matter of my internet connection but it seems that's not the case, my new phone can play it just fine. i planned to bought zenfone 3 before but i changed my mind, i'm just glad that i'm not captivated with it's 'high spec' or else i'll regret it for years to come. I don't know about zen 3 performance tho but i just hope that asus is not only showing it's 'superior' spec as their main selling point and turns out that the performace of their phone is a disaster.

Anonymous

I'm also thinking of getting this device but I'm getting the special edition one. Currently I have the S4, and after seeing the camera result of the Selfie I'm bit disappointed with the image taken with it. The photo was dark knowing the Selfie have a better camera spec compared to the S4. I must say the S4 have a better camera compared to the Selfie after viewing the photos in a laptop. So I'm still undecided if I should go and buy the Zenfone 2 Special Edition.

AnonD-633873

I bought the ze551ml (the one with 2.3ghz intel/4gb of ram) about 6 months ago and so far I am loving it. It is by far the best phone I've owned (my previous phone was the galaxy s4). It has great features. it runs smoothly and is very snappy. I used stock lp, then went to mm and now I'm on CM 14.1 running android 7.1.1 and I absolutely love it. Of course it has some problems, the battery could last longer and the camera, even though when it has light it works briliantly when it takes low light photos it lacks a bit of quality. Overall I think it is a really good phone and recommend people who are looking to buy this to do so

AnonD-197217

The problem with zf2 MM starts from many aspects, battery drain is the main one. It just drains too fast, 100 to 90 in a blink, when using LP can go almost twice the time. I have to admit, many bad reviews, but the cause is not unknown : using heavy load tasks while using 9v fast charging. 80% chance u will damage the touchscreen and lcd. No smartphone will survive 4 years, let alone the battery it self. Phones with fast charger have shorter lifespan. I predict this phone can go up to 2 years more max. Unless they kill Lollipop this year. Then bye bye zf2. MM really kills this phone. Trust my words.

AnonD-197217

download from asus official website and put it in your sd card. Will update it self. Because as an update version it is later than MM update, but the OS is LP. So the phone will recognize it as an update but actually a downgrade.

AnonD-197217

No, u download from asus website and put it in your sd card. Will update it self. Because as version it is later than MM but the is LP. So the phone will recognize it as an update but actually a downgrade.

MM will definitely mess your battery life. Find a reversed update in the official web to revert back to LP. You dont want MM for this phone.

The battery life is so bad i just play 1 stage on Brave Frontier and i lost 12 pct battery vs my S7 which does the same battle but loses 1pct. Regardless of how much speed you get that battery life is only about 30 minutes on mines.

Hi guys, I recently bought Asus Zenfone 2 Z00AD (1.8ghz/32gb/4gb RAM) and i was impresssed about every aspect from this phone, premium build & HIgh-end specs. But after weeks of using it, the heating issue and the battery draining part really turns me off. Like I have to charge it more frequently unlike my recent Huawei phone. Done all the updates including the latest .223 firmware, OS upgrades to MM, and system battery saver but its not enough to last a day. Hope guys from ASUS don't abandon all of their recent flagship device that badly needs some stable updates to have a much better performance as they promised. .

Zac

As prepared as I was when I bought the for I was not prepared for the issues that it brought. Main issue was that any update from Asus immediately caused my phone to crash and forced me to completely factory reset, (happened over 3x's). Next issue was half n' half, any app that needed updating from Google Play could and would cause my phone to restart on its own giving me a SD card error. Battery dies way too quickly, I'm beginning to charge it more and more. Brightness can sometimes suck. I've had this phone since 04/05 of 2015 and its been the biggest disappointing thing ever! Along the biggest waste of $300 I've ever spent. Asus support is and forever terrible. I don't recommend any Asus phone period.

On youtube, only Full HD is supported. If you take a 4K video into the storage and play it using VLC (for example), the phone will play it but I hope you're smart enough to understand that a 4K video will not be shown in a 4K resolution when played into a Full HD screen...

The problem you had Marshmallow, what version of Marshmallow was it? And when did it start? was it right after you turned it on, or after some time? And would you recommend it to someone who wouldn't buy a phone for the next 4 or more years? I'm asking cuz, I want to know if the low price is worth it for it to last, after years of usage. And I have seen alot of bad reviews about Zenfone 2. Thanks in advance :D

sutton0028

I am seriously trying hard to move on from this phone, but haven't found any reasons to. - it had problems with Marshmallow [battery drain, and bluetooth lag], but then i found reversed update to lollipop from asus official website, and it is working amazingly well again. [Seriously, who needs M when L is doing better?] Almost 2 years of using this phone - RAM still breathing comfortably. 4GB [free unused ram sits comfortably around 1,5GB to 800MB] - one thing to avoid, is using the fast charger while doing some heavy tasks. [ may lead to overheat] > only use the fast charger when you really need fast charging, and for the love of God leave it alone when you do charge it with the fast charger. - one may think that this phone is obsolete, sometimes i do too, but again and again I was proven wrong. It scores an amazing 60k plus on antutu 6.2 - 4G connection works with no problem whatsoever - camera is basic, standard quality, but well, enough for me. [not in anyway bad at all, unless under low light condition] - the backdoor, 3d illusion zencase, only costed me under 4USD, cheaper than buying a case over it [which makes it thicker]. - the audio wizard works wonder for my music. - had cycling accidents twice, broke the screen twice, bought screen replacement twice for under @30USD and works like new again. - never had serious lag - never had serious heating without the fast charger - perhaps size and weight are the only problem i have, but then again, i am used to it.

This phone is good but I cannot recommend it for everyone because of many things. 1. ASUS never release an official FOTA Marshmallow update for zenfone 2 ze551ml. They did release an downloadable update but not entirely stable and I read many users regret updating because plenty of bugs. 2. At some point when I updated the firmware, SIM 2 slot has been malfunctioning ever since. Even there's sim inserted sometimes it cannot detect the sim so i had to restart the phone in order to detect it. But it happens frequently so I gave up using Sim 2 slot. 3. Battery drains so quickly. Even in standby mode the phone hardly last a day. ASUS promised to release official Android marshmallow update FOTA but never happened. Asus Zenfone 2 ze551ml will be the last Asus phone i will ever purchase and stick to phone brands that continue to support their previous phones with updates.

same thing happen to me when i bought my first smartphone the asus zenfone 5 .it was fantastic the first year then after that it started heating up like hell and for some reason asus zen ui (lollipop 5.0) have bad memory management and the phone lags to much and i had to switch to other phone and never bought asus again.

Sutton0028

Most of the ghost touch problems came from over heating ( using the fastcharger while playing games or heavy tasks ) can replace the lcd, costs only 30usd -ish. In my exp, the original 9V fast charger works damn good, but dont even think to do some heavy task with your phone while at it, esp* watching hi-res youtube video streaming. It is better to charge with a standard 2 Amps charger, cooler and perhaps only 30 mins slower.

Sutton0028

Dont update to marshmallow. Or do update, and find the reverse update to lollipop. Marshmallow will mess with your battery life.

Kupao

Had ghost touch issues within the first six months. While it was resolved in 3 weeks (I thought that was good enough for me considering I was promised that it can take more than 1 month), I am now experiencing loose socket issue on its 3.5 mm jack. Still 3 months before my warranty expires. I like the overall package even more than the current Zenfone 3 lineup (decent, if somewhat incompatible at times processor, adequate amount of RAM, decent storage space and highly competitive price) but I am sort of disappointed with the durability side. Waiting for the upcoming Nokia outings and hoping their new phones will be built like tanks.

it's so fragile,speakers won't work properly,hangs way too much ..don't buy it.It's a waste of money

Sometimes the cause of Ghost Touch is the tempered glass especially cheap ones. Got my 1st cheap tempered glass(installed it on first day) and thought that my ZF2 is having touchscreen problem. Ditched my cheap TG and got a branded one. No problem with Ghost Touch (and proximity sensor).

Zenfone2 sucks

Are you sure you are talking about asus zenfone 2?😂😂

AnonD-538254

yep this guy is totally correct....ram just plays fulfilling task in gaming and major part is played by the GPU and CPU

AnonD-538254

hahahah who said u that higher ram gives better gaming....bru higher ram gives u better multitasking options game performance is mainly affected by cpu and gpu..

if you have 4GB it will allow you to work of multiple apps faster same goes with games..

How many hours battery standing at 4gb ram?

Geek

Sir, the one who is responsible in GRAPHIC GAMES is GPU (GRAPHIC PROCESSING UNIT) not the ram. GPU renders 3D graphics. RAM is (RANDOM ACCESS MEMORY) that responsible for the storage of arithmetic and logic that CPU uses for processing data.. thats all i know. correct me if im wrong. even though you have a highest ram in the phone, but you have the lowest GPU, 3D games wont work smooth and fast.

metalbassist

Excellent phone! Highly recommend it. Some tips (albeit obvious) for newer Android users: 1. Keep your screen brightness down to conserve battery life. Don't use battery apps!!! 2. Go to settings, then storage, and then look through all of your apps. Force stop/clear data, and disable every app you do not use to free up space and have less background processes. 3. Move any app that allows it to an external micro sd to, again, save space. 4. Every day, go to storage and look for cache, and clear cache to once again free up space. 5. (optional) power off your device every once in a while. It helps. Hope this helps some folks! Enjoy your devices! 😎

I just used it for 4 months and the screen always flickers and I just found out it's usually the problem encountered by other asus zenfone 2 users. I just wasted my P15k, never again asus!

customer from BG

I bought this phone 1 year ago. The first 6 months i didn't have any issues, but last several months it started doing very anoying bugs. When somebody is calling me, the display is blocking and does not respond. Also when i'm calling someone and the line is busy, the display is blocking again. After restart everything is fine. This issue happens 4-5 times per day and i'm very angry about it. I wrote several times to Asus, but nobody replied. I think it is a software problem, not hardare. Anyway, because of this bug and because of the non responding from their side most probably i will never buy Asus again. I was very excited from the beginning, but afte the 6th month i was very dissapointed.

Hey, I am experiencing the same issue (LCD Screen hardware issue). You need to get it into a service centre and they will replace the LCD for free. Just bring along your proof of purchase.

AnonD-613376

Go for Samsung.. better chipset, hardware and performance.. dont buy this crap

The phone is capable of Asphalt 8 or even Asphalt Extreme. Its just that the hardware is unreliable. You might end up throwing your phone after 3mos or so

AnonD-613376

same here, dude.. its a hardware issue that Asus needs to address

AnonD-613376

I hate this phone! the screen flickers and half of the screen turned black. The first unit that i bought lost its loud speaker after 3 days then i have to rush it to the service centre to have it replaced. My experienced with Asus ZenFone 2 was not impressive at all. I will never buy any products nor recommend it to my friends, families and colleagues. I hope Asus will find time to address these hardware issues or they will continue ripping consumers off!

Arikado

I don't know how to say since many haters said that this phone is worst but for me, this phone i absolutely great.. They said the life span is 1 year or less but i used it 2 years, nothing wrong. They said performance is worst but it didn't happen to me.. The reason why my phone sometimes laggy is because i rooted the phone ( just imagine, you have 2 gb ram and 8 gb storage and you just like "well, let's shove another 12 gb files in this phone and see what happen" ofc, the phone will become laggy ). The only bad is if you're gamer like me, don't buy this phone.. not because of battery, but some game is not supported in intel-type phone

AnonD-474413

I purchased the Asus Zenfone 2 ZE551ML June 2015. By August 2015 the screen was all black. I ended up purchasing a ZTE and used that for four months until I had the Zenfone shipped to a refurbishment center to get it corrected. Over the last two month there have been issues getting the phone to charge as well as to power up. The phone is no reliable enough for heavy users.

Oddie7

Is this phone good for gaming? If I played Asphalt 8, can I set to high graphic settings?

Edit to my previous post: Hardware is good, except for 1) camera sucks, and 2) battery life is awful, which was supposed to be fixed with upgrade to Android M, but given ASUS's past performance, that seems unlikely to ever happen.

Anonymous

Have used this phone for over one year and a half. No problems at all, amazing camera and smooth performance overall

Marv

Should you buy this phone? Hardware is good. Customer support sucks. No update to Android M even after many very public promises. Advise that you avoid all ASUS phones for exactly this reason. Read the many comments here, and you will see that I'm not the only one with this opinion.

Ghost touches have become a problem after less than a year of owning the phone; causing the screen to jump around all over the place. Pictures taken by the camera are less than satisfactory. Speed good, memory ample. Support not very good, rather incompetent staff. I probably wouldn't buy one again.

Hey Jimmy. I had the same issue recently. What needs to be done is: remove the battery cover, u screw the backing of the phone itself from the battery pack and use a screw driver to detach the batterycked from the device wait 60 seconds..then reconnect it.tmThe unit should vibrate it begin turning in shortly thereafter. YouTube has a video on this. Good luck!

AnonD-474413

Most likely you will have to go to a repair shop. They can take out the battery and put it back in to get it to turn on but the battery is most likely the issue. I recently had my phone's charging port changed and have gone back to the repair shop to have the battery removed and reinserted.

AnonD-474413

My Zenfone 2 has had issues since I purchased it in June 2015. It had to be sent back to the factory last year due to the screen being completely black which was most likely a software update issue. Now, I have had the charging port changed but the problem most likely is the battery. Was using a different phone from August 2015 to December 2015 until I had sent the phone back to the factory for the software issue. Really cannot understand why a phone like this has so many issues. It does have 4 Gigs of Ram and 64 Gigs of internal memory. Sounded like a bargain compared to a Samsung Galaxy S6 but the issues make this phone highly unreliable.

I am one of those people bought this phone during its launch period. Till now i haven't experienced any major issues using this phone.This is a Very good phone according to me. I have updated my phone to marshmallow last month. It affected the stability of my phone a little bit. It freezes randomly during some operations. I haven't experienced any ghost touch problems yet. May be my asus flip cover helped me to protect my screens.

Diane

a big portion of my job is to be on my phone at all times during the day (I'm the social media and marketing coordinator) I can get 2 days worth of battery on my phone working from 930Am-6pm and various little things at night like my sister texting me. I never let it die though.. I usually just put it on the charger before I go to bed and it's sitting at roughly 55% each night when I go to bed.

I have had my Zenphone for about 5 months...I don't do any of the things you describe and am very...I mean OCD level meticulous with my things. Had a case from day one and screen protector. Yet 5 months in I had to send my phone back for warranty repair due to the ghost touch issue. Don't assume everyone is careless with their device. You just never know when your number might come up for this issue. It's a pretty well known problem out there.

This phone worked for about a year but then I have this random ghost touches while typing. Frustrating indeed to have a poor quality phone from a company that prides itself of quality products, not this phone. My confidence in Asus phone is just not high anymore and will no longer recommend any phone from Asus until I'm convinced that this quality issue is not prevalent on all Asus phones.

RADUM1978

I have last week on the Phone ''Return to Factory Settings'' performed. Since then the OS versoin of Android remains ANDROID 5.0 Lollipop. The Phone finds no update.. Do you have any ideea why It is not possible to update to Android M? Best regards, thanks in advance!

DAZ

Boy, this phone does not have official update to Android M. Remove that, also the phone is pure shit. It comes with a defective problem that it gets locked on smartcover without you using any. A problem that came from the Zenfone 5. The only way to fix that is MRA so if you buy it just get ready to send to MRA. There are no factory reset or anything that can fix that. The camera is slow, I mean, very very very slow and apps keeps crashing for no reason. Only good thing I got from it is the battery that lasts 3 days since I don't use it to much to not get PTSD.

TrollingZenny

or you could just throw it screen first onto a brick wall or throw it in the middle of the road in heavy traffic.should totally fix the problem either way...

AppalledZenny

i'm kinda appalled looking at all these negative opinions about the Zenfone 2.mine has been working pretty well up till now and it still works well.its either you people don't know how to handle your phone with care or you don't fully understand how your phone works.this 'ghosting screen' issue seem to happen to a lot of you and the only solution is to stop putting your phone on your back pockets to avoid sitting on it and as a result,cause damage to the digitizer which causes this 'ghosting screen' problem.also stop wearing tight pants and forcing the phone in your pockets which causes the screen to slightly bend and affect the digitizer.if you guys can't take good care of your Zenfone,go get a Nokia 3310 or something.

Shaik

U r mobile volume going down When u insert ur headfone,please try to change different headfone

teewee231

Asus zenfone seemed like the best choice for an affordable but still good quality phone. I've been using it for a little over a year, and all it wants to do now is phantom glitch the shit out of my day. I can barely use it for more than a few days without problems. It'll mostly phantom touch the screen near the top, so any type of social media or googling is delayed x100 because I can't get the damned screen to stay in one place to type. I will never buy an asus product again, esp after reading that this is a common problem and asus is not doing anything about it. It is an extremely frustrating problem that I never had to deal with until now.

misc

Yo man, my experience with zenfone 2 is the same with you lol. Zen 2 is quite a nice phone but yeah, like every product, no product is perfect, they will have one or two or three or more defect but nonetheless Zen 2 is worth to buy tho.

But now everyone here is complaining A LOT about it that I don't even know anymore. I was between the Zenfone 2 and Zenfone Selfie. Now I just don't know what to buy anymore, since all others is more expensive with 'less hardware'.

longtimeuser

If you have a plan to buy ASUS ZenPhone 2 ZE551ML, consider these limitations: 1. Erratic G Sensor. There's no calibration settings. 2. The Data connection only available on SIM 1. So you can't switch mobile data to SIM 2. 3. Auto light sensor are not "smart", low brightness in highest setting. 4. The bottom case isn't flat, the device moving like a boat. 5. ZenUI auto-update reinstall Zen Circle even that app already disabled.

LOL..do take note this phone I felt is quite heavy compare to lg g4.

Yesbee

Just about an year (15 months) ago, I bought this Asus Zenfone 2 with 4gb RAM and 64gb HD for $299. Last week I did accept the system update pushed by ASUS and it did install and while re-booting it just went blank screen and never switched on again. Tried charging overnight and then tried fastboot without any success. It does not even vibrate when power+up volume button pressed. I called Asus customer service and the answer I got was warranty has expired and the estimated cost of repair will be $165. This phone broke soon after the warranty expired. That's all the life of Asus phones??? I lost my trust in Asus products and their system update software. Looking for a much better phone with a reasonable price. Not sure which one to go far. Hope this review helps others in deciding whether to go far Asus mobile phone or not.

gaurav big-G

I don't understand why you buy Old model update with the new device and latest OS version.Intel is no more in mobile market and all Intel powered mobile having so many issues.Don't buy Old model buy new devices.In old model consider only Nexus 6 2014,2015,and Samsung Note 5,or iPhone 6 6 Plus or 6s ,6s Plus in low range buy Moto G 3rd or Moto X Play,(Moto G 4 Plus is best Smartphone under 15K) everything in this phone is perfect.All these devices will serves you great.

As my asus zenfone 2 4gb version was under warranty, the service centre replaced motherboard as well as lcd panel to get rid of the only problem i faced (i.e. GHOST TOUCHES which were getting more severe day by day) they started around July August period in most of the asus zenfone 2 sets i guess, must be due to some software update.

No issues after upgrading, phone is faster than ever. But still no change in Android OS consuming the hell out of the battery. Never seen anyhthng like this before. Thinking about rooting it and see the wakelock pattern. But the process of rooting it, is cumbersome after upgrading to Android M! One false step and you are done for. Any new ideas friends??

This is the WORST phone I have ever had in my life. Neither of the sim cards slots work. The screen randomly glitches and WON'T stop until I throw it in the ground. I've had two of these shi**y phones within 2 or 3 months of each other. Never again will I use this brand out this phone. ASUS IS THE F***ING WORSE!!!!!! I'D GIVE 0 STARS.

steev

This is a great phone, I've had it since January 2016, the only issue is that for t-mobile it lacks band 12, so you will not get LTE in a lot of places, you will get 4G mostly all the time, but if you like streaming videos a lot, than is not recommended for t-mobile, you should have no issues on at&t, the software is very useful, a lot of people complain not upgrading to android 6, but to be honest, Asus does a lot of updates to keep the phone in top performance.

Worst smartphone I've had. The sim slot is faulty and the micro some slips out 2 x a day. Asus will repair but it will take 2 months after I send them my phone to send it back. Look up this problem it is very common to this phone. This phone also "buttdials" all the time. It never locks. All of a sudden my phone starts playing music or calling the emergency dial. Wtf??? Apple never did this.

Got the phone back from the Asus Service Center - they fixed it in one single day (although the phone was returned after a week since sent, because of the courier company). The issue was the display module, which was replaced entirely. Hopefully, they did not messed up other things, because now I have a soft annoying noise in the ear speaker during phone calls, but I can live with it.

unlock the bootloader on ur device by downloding the official unlocking app by asus and the install custom recovery like TWRP by the help of a pc......ull get the info of installing this....its simple....just install adb and fastboot ,ull get these on xda forums...then download twrp for zenfone 2 z00a from the official twrp website...the write the commands in cprompt.....after getting recovery installed u can go to twrp by pressing volume up and power key together ..select reboot to recovery and them install cm13 from there......just head over to youtube ....one thing...fm radio does not work in cm13 for this device

Hi. Bought this mobile (new model) few days ago. I think battery runs out to quickly. In the morning fully charged battery in the night completely runs out - it does not pass the 24 hours. I don't use the phone much in my job, after work I'm browsing the internet - that is all. Is it normal? Maybe problem is that the phone bought from the shop stand?

Qoghnus

Android MM official: My battery was 80% last night No background was runnung,my wifi was on I let the phone be awake This morning was 20% !!! I checked the phone,no app was in the background I "power and boost" the phone,changed it to super saving But after one hour,the phone was off !!! I dont know what happened,but something drained the battery very bad. Lots of people had the same problem when I described it in XDA

yes, it is great telephone. I enjoy it. It is superior in nearly everything even than iphones, and for like 1/3 of prize. However I would reccomend you to buy newer ZenFone models :)

What is cm13

Vee

CM13 works excellent on ZE551ML! I have been using it for quite some time. Performance is better, use significantly less memory! Just be noted that the following are not working at the moment: - Display turns black for 2-5 seconds sometimes when some apps change the display mode. Just wait for a few seconds & things will work fine. - No FM Radio. - ASUS Cover app does not work fine.

6 months back i have upgraded my phone from Samsung to Asus, i want to tell u the features about this, First of all ,i have never expected that no other phones can be bad as like Samsung but Asus broke that. Initialy i faced- call was getting disconnect automatically and after 2 months it was started hanging and it's as bad as Samsung. Camera quality z too worst and also battery backup. Its key button and power button seems like very ordinary as like they hav just done welding in a regular shop. i am not able to send a image file or else i would hav send it. Fact is i am not only 1 user getting this problem.my other friends are also using Asus having similar probelm. Initially u will feel there z no phone like Asus after 4-5 months u will feel the same but in a reverse way. Overall i would prefer to repair my old Samsung phone and use rather taking a new Asus.

Ari

This product was a waste of money for me and material for the mother nature. Microphone broke in less than a year and no one can hear me unless I use earplugs or loudspeaker! Screen has gone crazy too. randomly calls people, zooms in and out, flickers, get unresponsive etc. No proper support service either. So regretful of trusting this company

For double tap to screen off you change it in settings-->zen motion-->touch gesture-->screen off and make it ON. After update some settings have changed. LED indication still not yet resolved.

guy i would advise u all to stop using the asus zenui and flash cm13 .....i am saying this becoz many ppl including had faced motherboard faliure...my story is with two phone..one was zenfone 5 whose motherboard was burnt(een without intensive usage) and the other was zf2 of my relative...it got bad just after the end pf warranty and he was asked to pay 16k.......j know that asus is best in motherboard but believe me guys they are worst in software ..they just roll out softwares without proper testing and the after effects are faulty devices with burnt mobo and other issues..now as chanogenmod officially supports this deviC its awesome...cm13 works like charm and at any time u will get more than 3 gb of ram free...cm13 is having each and every feature which zenui has...rapid charge,double tap to wake,camera md other lock screen gestures etc....so my kind advise to increase the life of ur devices is to unlock ur devices bootloader,install custom recovery like twrp or cwm and then just take the best out of ur phone with cm13.......moreover in just comming months it will get android 7 via cm14...

AnonD-538254

it works awesome....its the best i would say...fast charging ,double tap to wake...everything is working and there are no bugs......after getting fed up with the zenui mm i took this step and now i can feel the real power of this dragon

I have bought Asus ZenFone 2 ZE551ML (Intel 2.3GHz, 4GB RAM) one year ago (Romania). I was very pleased of it and the phone worked very fine. Even updated to Android M and everything worked fine - no issues. But, now there is an issue: - About a month ago the screen started not to be so crisp as usual, the text and icons have some sort of shadows under (like melting). Even some gray vertical lines seem to be visible sometimes (very dimmed) on the whole screen. - Almost weeks ago, the phone started to have big issues: it does not display/update the image entirely on the screen (80% of the screen is either black, or only shows some colored vertical lines), but the touch screen is functioning (sometimes, I manage to launch some apps and the display works for them, but it does not in the usual screens/menus - app drower, OS menus, scrolls etc.). I even disabled hardware overlays and completely reset the phone (hard reset), but to no avail. Now I'm about to send it to warranty... after paying around 330euros and using it for a year :( Great phone, but I've seen many people complaining about the same issue I have. Also, we have been waiting too long for the Android M update. I'm a big fan of the Asus products (PC-related stuff) and I didn't expect for this to happen in the smartphone area.

is this asus zenfon 2 have a multi window like samsung ?

Thumbs down Asus!!!! Your motherboard kaput exactly after the expiry of the warranty. What a waste investing in this device. I am very unhappy with it. Two major problem in 12 month! No more Asus in future for me.

Don't worry. The downgrade procedure is a standard after each main update. I'm using the official Marsmallow on my Zenfone 2 (no technical issue for now).

Asus released a downgrade from Marshmallow to Lollipop I'm using Marshmallow but most of the sensors like proximity and gyroscope aren't working. Hope Asus fix it soon.

The MM update is horrible. I updated to MM and factory reset my phone, wiped cache partition, and still the phone HANGS A LOT after the update. It keeps hanging and you have to restart the phone everytime it happens. I restart the phone like 10 times a day. Hope Asus release update for bug fixes.

You can install the Asus Backup App to backup everything before factory reset.

AnonD-569439

So the Android M update is finally out, but after reading a few comments there seems to be some problems with the sensors after updating. Then a few people said that after upgrading, doing a factory reset should solve the sensor problem. Which brings me to 2 questions: 1. Can someone give a step-by-step process on how to back up my data before a I do a factory reset? 2. If i'm somewhat no6 pleased with the upgrade, how do i downgrade back to Lolipop? Thanks :)

As per my opinion, it was a very much impressive phone but since last 1 week my Zenfone 2 gets heated up very much. Even the battery gets down within 6-7 hours which used to run entire day previously

I have a zen2 here 2gb. It has been working good for the past year and a half. I did receive updates as well several times. One issue that i did encounter is sometimes it hangs or restarts buy this is probably due to intense gaming. I have been playing online games like clash of kings f9r several hours a day continously and had the drive space of the phone almost maxed out. So i guess this is one of the reason.. It's a good phone. I even dropped this countless times in the bathroom floor and in my room, highest being 2 meters in height. Not a problem. The only downside i have found is in terms of memory usage. No matter how many times i try to free up memory, clean apps it really only goes down as low as 950mb ram usage.. its half of 1.8gb ram.. but overall very good for 5he price range.

I am experiencing problem #2 for my slightly 1 over year zenfon2. Never thought such a reputable company could come out with such crap phone.

Billstpay

I Have had a Zen 2 phone for almost a year. and had no problems at all that has not fixed itself in a restart. Camera is great, Speed very fair, comfort in hand great, Glass not even a scratch without cover since new. Price was $200. that"s 1/3 the cost of comparable phones. The Intel Chip seems to work very stable. Sorry to see it go so soon and not improve.

Mike

Great specs. But after having a Zenfone for a year and with the new zenfone 3 about to come out I really felt the obligation to warn people about things I never considered before buying it... 1- The WORST customer support I have ever come into contact with. Ever. This isn't based on one experience either. Ive had to deal with them several times. They are incompetent and a bunch of liars. This point is shared by many users on the internet (just do some research if you don't believe me). So why does this matter?.. 2- You will have some sort of technical problems with this phone eventually. Most likely the screen will begin to freeze or show lines. This is a known problem with this phone. Again. Do the research and see how many ppl are complaining. If ASUS was a good company this wouldn't be such an issue but... 3-Replacing the device is a straight up nightmare. Took me 3 months to finally get a refurbished product. Plus several hours of chasing these morons to find up what's taking so long. Their answers are mostly lies so this will be one of the most frustrating experiences for you. 4- You will never get an update. I can promise you that. This may not matter to you but it does to many phone consumers so I felt the need to say it. They started by lying to us that a 5.1 update was "soon" coming to the device. A year and a half later they are saying the 6.0 update will soon be coming to the device. We never got 5.1 and when you realize what a bunch of liars this company is made up of you will know that there is no 6.0 update either. Nougat is around the corner so the fact that zenfone users are still naively waiting for a 6.0 update from a company who has basically just dropped them once they bought the phone...well it's just wrong. This will be my last ASUS product ever. I know they make solid computers but I'm just so disgusted with this company I will never buy from them again.

Please, don't let the good specifications fool you. The phone works until it doesn't. Visit the official forum It's full of complaints, especially regarding the battery. The assistance is also not good. My phone is still under the 24 months pick-up & return warranty, but they wanted me to accept to pay 35 Euros + taxes and shipping if, for some reason, they don't discover the reported issues. Buy something else, with lower specifications, but better durability and assistance in case of fault.

I don't feel that it is fair with any customer that this company is selling such kind of mobile phones which can't even survive for 15 months and they are promising things that they cannot even fulfill properly which is highly disappointed....

What system are you currently using? Do you mind to share?

It's a good phone (I'm happy with this phone for 1.5 years - no heating problem on my side) but now I will not recommend to buy it. You can find better phone for a better price, or maybe wait for the Zenfone 3. Question: Why do you need to play 4k videos? The screen is only 1080p and it's not a MHL compatible.

Dio

Plzz tell me! I m very confuse which mobile buy it worthable for asus.. Zenfone 2 ze551ml good or not mobile? It's heating problem or not? It's can play 4k video or not?

I use this phone (4/32 version) since 2 months. Disabled the bloatwares, use Greenify and SD Maid. Good battery time, the phone is fast, no lags, no bugs. The camera app now is good, except the video quality. The future updates should focus on brightening the screen and add some volume to the speakers. Recommended.

why is it that my phone charging takes me a lot more time???

There will be the baterry change of asus .. where i can buy it

I had a problem with a speaker just after a 4 months. Of course I ordered the speaker on ebay and now it's ok. Otherwise, cell works fine for now.

Hey, you need to calibrate you battery... Try this one, Used your phone until the battery drains or until your phone will shutdown. While your phone is off, charge it and do not turn it on yet. When the LED Notification turns yellow, it means your battery is full but do not unplug the charger yet. Turn on your phone until its open, then unplug the charger. That's it, hope it will help. Please give me a response once done. Thanks.

My phone zf2 also shutdown at 60% What I can do

AnonD-462236

you can say i was on the brink of just getting this one, it was closer than you think cause when i saw 4GB ram i almost ordered it. Thankfully the Moto X Pure Edition came out during that time, i got the Moto X Pure Edition, one of my best decisions in life.

Not a bad phone. Its gone through water damage twice, and still survived after a drying session in rice. Now its getting heated up after the second time i sweated on it too much. Lasted a year with this kind of abuse.

Had this phone 2 months. Ready to thrown it on the highway. So sick of it, cuts off by itself, apps always saying its a problem. Never resolves itself. Won't Go back to the home screen a lot of time and has 0 value trade in. Sick sick of it. Will b moving on

How's the marshmallow update (manual)?

Anonymous

By the way Dness, you must calibrate your battery first. Just try this once. Use your phone until the battery will drain and be at 0% and automatically your phone will turn off. Then charge it while the phone is off and when the LED notification becomes Yellow Color, do not unplug the charger, just turn on first your phone and when you see your phone at 100% battery, that's the time you unplug the charger. Afterwards, do not make your battery drain again to 0%, when it comes to 15% or below, charge it and do not use it while charging, and unplug your charger only if your battery meets 100%. :) This is the proper way of taking care of your phone?

Anonymous

Don't worry, just keep your phone charging and maybe it takes 3 to 4 hours to make your phone open or atleast the Battery Charging logo will appear. It also happens to me, and the main reason why is because these units are too old, they just stock for a long time and you've bought it just now, so the battery will drain to the highest level :) Trust me... And don't worry too much.. :) Please give me a response after.

polletje

The phone looks good and feels good. The screen is a nice quality. Those are the good things. The bad are, random reboots, touchscreen not responding, the battery dead in 4 hours, most apps not working well. No fingerprint sensor considered all its a very mediocre phone not worth the money. Better buy elephone cost less and is more phone. Or the know top brands and models

I wonder how you guys use your phone? I have been using Asus 5 and 2 years now and it never went dead. Though battery has degraded still it turns on so you guys are just wreckless users and any phone you use would die.

But it generates alot of heat and battery drains faster than ARM chips which are specifically made/started for mobile devices. And as of now Intel SoC has been dropped and are no longer in production.

I scored around 64000 on antutu with this phone ;)

AnonD-569514

I Don't know about other phones which are coming in the market but alot of people are unknown but the fact that this phone comes with Intel Atom Z3580 which is indeed the fastest chipset if talking about price range ... Phones nowadays are coming with high end specs except the processor.. If you open ANTUTU (1st official and popular benchmark test website in the world) you will see the chipset performance in 2015 q3 there are phones which have snapdragon 805,810,808 these are the chipset which comes in note 4 , note 5 , S6 , sony x 2016, Lg G5 .... these are the phone which scores around 60,000-80,000 scores and comes at 7th position... phones coming with snapdragon 615,617,800,801 etc are coming at 22nd position... people are just buying phones for RAM AND CAMERAS They think snapdragon 615,617,901,808.805 phones like Motorola G4, Motorola G4 plus, Xiomi note 3, Lenovo k5, Samsung S5, samsung S4 , Samsung A,O,J,E,S series are faster ... LET ME TELL YOU SOMETHING "THEY ARE NOT" They may look good , they may have good camera, they may have 4 GB ram, but they are slow as hell they scores around 30,000-40,00 THE ONLY PHONE WHICH ARE FASTER THAN THESE PHONES IN MID RANGE IS ASUS ZENFONE 2 (4 GB RAM) AS IT COMES WITH Z3580 THAT SCORES AROUND 58.320... AND YOU CAN CHECK THE ANTUTU SO MORAL OF THE STORY DON'T BUY PHONES WITH JUST RAM AND CAMERA AND PROCESSOR (PEOPLE WHO JUST BUY PHONE BY HEARING OCTA CORE PROCESSOR).

my phone also died in only in 7 month WHAT i have to do i don't know this mobile shuck my mind

It was a decent phone, but it died on me after 9 months. It won't turn on. It could be fixed by doing troublesome unscrewing or taking it to service centers. I'm never buying Asus again though.

I TOTALLY agree with Carlf! This is exactly what is happening to my ASUS phone starting few weeks ago. Its really frustrating and annoying! Im thinking to buy a new one instead. Just to share, I had a friend who had the same phone and just last week hers just didn't want to open, so she had no choice but to buy a new one. Then she remind me to start to backup my files the soonest coz ASUS is NOT stable. Sorry to say!

I like my Zenfone 2 (ZE551ML) bought last year. At this time, it was the best model (price / specification / quality) and all reviews were very positive. I have no problem with my phone btw. Currently there are a lot of better phones around 150-250$ like Honor 5X or Motorola G4 Plus. Nobody who is a little bit serious will recommend to buy this phone now - and it's perfectly normal.

Carlf

I've had my Zenfone2 for over a year with no problems at all EXCEPT for the past 2 months where the phone has become VERY unstable. Apps will open all by themselves, screens will change within an app, windows will not scroll (although they will scroll all by themselves), can't get back to the Home screen, opens 9-12 apps all by itself, and I loose the ability to power on/off or reset the phone. All of this happens completely on it's own without me laying a finger on the screen and all at the SAME TIME!!! The latest software update did nothing to help. Can't seem to find anyone that can offer a suggestion other than get another phone.

Some people are angry, but on my side, I have no issue (for 1 year now) with my battery or Asus techies. Everythings work well and if you follow the official forum, you will see that the 6.0 version will be soon ready. But one true thing, it's a little bit sad to get the new version so late.

I bought a zenfone 2. It was cheap and you get what you pay for. I was promissed Android 6 update. So far it didn't happen and I don't think it will happen. I will not buy any other Asus devise. Some of it is my own fault. I should have done my research more careful. Well my zenfone 2 is probably one of the first once sold in USA. Maybe I should wait a little longer and see what other people have to say about it. About the customer service, about the Battery life, or about the company in general. Am I going to buy another Asus product? NO.

That's not true. Zenfone 2 ZE551ML (all versions) are compatible with the fast charging, but only the 4G/64G (and higher) gets by default the 18V charger. You only need to buy this charger...

Worst phone ever. I got i hopes for this phone. I got battery problem in just 10 months of using it and asus support is so bad that they can't even fix the problem. I already gave them my phone for almost 2 months but when i came back and follow up for my phone, thats the only time they are really trying to fix it. I also paid for the battery becasuse the battery warranty is only for 6 months. Even if the battery is already replaced I'm still experiencing the same problem. Dont buy this phone.

I see a lot of people complaining about bloatware and zenui. Zenui improved a lot. Much faster than nova. Just install zen marshmallow theme and you'll get a stock android speed. I'm not kidding.

Hey guys...i have bought this phone for 6 months and i've a problem which is the fast charging feature doesn't work again although i use the original adapter and usb cable from ASUS...please somebody help me ti fix this?

scarlet666

Bought ZE551ml 2G 16GB, bring it to travel in almost all condition including ocean (with waterproofing protection), still doing good today. Pretty satisfied, but I wish I bought the 32GB instead of 16GB that time, LOL. Quality of camera's still good. All apps works well, some are stopped or hard to open when first installed which enough reason to me to uninstall it before it get worst. Buy with guaranty and you won't be disappoint (black market phone always have LOTS BAD FACTORS plus you can't return it for reparation) and don't push your phone to work like other high-end phone, better use it with recommended applications for the best result. Worth the price.

Change the data cable and try with a different one

Uncle Buck

The phone is so so. Asus has definitely over promised on this phone. The worst is when you need Asus support. I've experienced my fair share of bad services from all over the world. But Asus has got to be the worst, by far! They can comfortably, completely ignore your requests!

still no update on new OS marshmallow and the signal is weak as hell! battery life is also questionable at best. thank god for the fast charging cos you would need it! bloatware is also a pain to remove. i like the design, screen and the gesture thing. it has NFC so that's good i guess. and the price is bearable. overall will NOT recommend this product! so many CONS than the PROS

AnonD-561627

well this is my first phone review in gsmarena. I'm from Indonesia and just bought this phone last week and so far it runs normally. although seeing all the comments here makes me worried about the future of my phone but my zenfone 2 has past the 1st week without any trouble (battery overhear, hang, restart, wifi / gsm problem, etc). at first run, RAM usage at 2gb+, leaving 1.9gb. after installing regular apps (socmed, skype, wa, line, games) it still had 1.7gb free RAM. plenty of room to download more app. and i would like to share my experience. i used the phone for 1hour++ using skype while opening PPT without charging the phone and my zenfone 2 still runs normally. no heat, no lag, no restart, no problem. the battery consumption also not that bad considering the heavy usage. and most of all, it saves my face because i forgot my laptop back at home and my zenfone 2 come to the rescue. i hope it can last more than 8-12 months like several users in here which have bad experience in that period. so to anyone that would like to consider buying this phone, overall in my opinion that zenfone 2 is value for money smartphones.

mika

Had the phone 7 months- it didnt work properly for a single day. Now it doesent even turn on and the warranty wont fix it.. WORST PHONE I EVER HAD - DO NOT BUY

Mikey

No anti-glare screen protection makes the screen reflect nearby lights and renders it impleasant to use. Poor location services in built in weather app: when in roaming, the phone absolutelly needs internet connection to figure out where you are. Also, location services simply do not get the accurate location even though the google maps app gets it on the same device. No such issue existed on other brands of android phones i used. Lots of bloatware that runs in background. Good thing is that its possible to disable them. Low sound quality, frequent missed calls/reminders because you just dont hear them. Poorly positioned microphone makes voice call clarity very bad. Annoying for people you speak to. Sim card holder is cheap & loose, so u need to get it fixed as the sim card falls out of its socket rendering the phone unreachable. No built-in "smart stay" or "smart screen" makes the screen go off while reading newspapers or watching a video for instance. Annoying. Google apps trying to solve this do not work properly. LED notification color cannot be customized and is predefined. LED is too small and can be omissed due to its tiny size. Awful camera makes poor and blurry pictures. Lots of interlace-type interferences when photographing the computer screen. Poor focus and image stabilization makes the majority of photos blurred. Even besides the 2ghz processor and 4gb of RAM it takes a lot of time for the phone to restart itself. 3gb of RAM are frequently taken by bloatware which reduces battery life. Built in keyboard app has the settings button awkwardly placed so its occasionaly clicked by accident when typing common texts such as sms or emails. Annoying. You cannot silence the Zenfone by flipping it over or upside-down. Other manufactures offer this option which is btw VERY usefull. Bottom line: avoid asus for now, they still have a lot to learn. Good price though.

I made the same mistake but I did 1 more that was worse, i also bought an Asus X555L note(to communicate with andvsave phone info). Asus is Throw it out &get a reliable fone. I have had 3 Zenfone2, the latest was the Deluxe Special Edition Zenfone2 with 128Gb onboard memory, after 3 months (with many issues in between) the battery went dead. Asus wont send me a battery and they want me to send it in with my persinal info on it sobthey can steal my information. The keyboard double ticks letters & numbers all the time. Asus Zenfone2 used to be reliable but their lates products are garbage. I also bought an ASUS X555LA Note(laptop) the key lasted 8 months before half of the keys completely stopped working. I threw the thing in the trash( minus the hard drive). DO NOT BUY ASUS PRODUCTS!!

After years of using Nexus phones I moved to the Asus Zenfone 2 ZE551ML 64GB/4GB version. Was the worst fricking mistake I ever made whilst picking up phones. Now after just 9 months of use I'm exchanging this piece of trash for a Moto X Play on which I'm sure I'll get Marshmallow and also further immediate updates for the next 2 years. Guess how much I'm exchanging my current zenfone for ? Just 20% of it's original price in 9 months, guess why ? cos I'm sick of Asus not providing updates. Will never again buy Asus products, forget the phones, will not even patronise and buy their routers though I always was a big fan of their RTN series of routers. So I have a Rs. 22,000/- phone that I'm exchanging for a Moto X Play and getting a reduction of 4,000 in exchange... bye bye Asus junk... A manufacturer who can't release timely operating system updates for their products does not deserve to sell their products to the general populace. For that matter I highly admire Motorola, I have picked Motorola phones for my wife for the past many years and she's always got regular updates. Even the Google Nexus phones are amazing in that sense, but I'm finding them pricey now to change every 1.5 to 2 years. Motorola is a better option since it's affordable and also is very fast in giving code upgrades ! So bye to this useless manufacturer, and henceforth I'll be patronising a manufacturer who is more responsible to their customers.

I strongly recommend to update your gapps too or to do a clean install. I did'nt have issue with my 6.0.1 after a clean install.

It's regretful to update my zenfone 2 5.5 system into Marshmallow cause there's a lot of issues when it comes to compatibleness. My phone is connected to wifi and there are some app that I can't access anymore esp play store and browser which are very important for me. I hope you Asus can fix this.

I have been an ASUS customer for a number of years now. Motherboards, phones, laptops, you name it, but this latest debacle of telling loyal ASUS customers that Marshmallow will be coming to the ASUS Zenfone 2 is the limit. Delays in software release happen, but don't lie, people don't like it. My next phone will not be an ASUS.

Hey, Tomorrow brings the end of Q2 and all the other Asus smartphones (except 1st gen) have recieved Android 6 (M) Update incl. ZE550KL that is Zenfone 2 (2GB). I hope Android M update for ZE551ML is released soon. Last by tomorrow. And, Yes the phone is really great and has hit the 27th position on AnTuTu Benchmark. The latest Zenfone 3 Deluxe (6GB) has ranked 1st and is the hottest phone right now beating Galaxy S7 in speed test.

I totally agree with how great the phone is! :) I just hope the Asus realizes that Zenfone 2 is one of the best phones they had created, next to the Zenfone 3 they announced lately, and hope they give this phone the Marshmallow update. I've been checking since day 1 of Q2 if the Marshmallow update is available. The knock knock does not work all the time, especially when it freshly came out of your sweaty pockets! :) LOL!

for all the zenfone 2 users who are plaining to get the zenfone 3 ..please dont because the processer powering the zenfone 3 is a midrange sd600 series processer which dissapointing compared to other better devices around the same or cheaper like the mi5 ,oneplus 3 that have a flagship chipset....the only thing better with the zenfone 3 is maybe the camera but the rest a pretty much the same

iLikeTurtles

I have this phone since January 2016 and all I can say is this phone worths buying ! why ? well, because it's good at that price, not to mention I got the android 6.0.1 beta wich is much more stable than android 5.0, the single problem is at the proximity sensor wich is faulty, you have to wait a bit to disable so the screen turns on during a call, anyway, it's just a beta , this problem will get fixed for sure ! 45k in antutu with my 1.8 ghz quad and 4 gb ram model [special model, z00ad] on android 5.0 now I got 58k , well, it's awesome and the games run much more smoother and better, overall performance is better, the phone is faster, the battery is kinda the same but overall is better ! Things bad about this phone, the battery cover wich cracks pretty bad if you remove it more than 20 times, mine cracked in 2 places, near the jack connector and near the top right corner, the glass is not so scratch resistant , mine scratched in my pocket and I always keep it with the screen facing the inside, not outside , another bad thing is that knock knock to turn on the screen, sometimes it gets on in your pocket and starts doing funny things like calling the police or your grandmother.... anyway, it's a nice phone !

This Zenfone 2 is on my list with Zenfone Max. Having tough time choosing between the two. Any issues with battery life? Seems this one has lower battery life and higher resolution meaning this would consume battery charge faster than Max even with 5000mAh. How about Corning Gorilla Glass 3? Any issues? I read some issues with Corning Gorilla Glass 4 but not really sure if it was from legit user.

There are two issues that I face very frequently. Can anyone help me with this :- 1. While touching the spacebar, the page on the screen vanishes, because the clear button is just under it. It's so frequent that, its rather annoying. 2. Same thing about the button at the right. Then one can't even get back to the page that one was typing... Lastly I can't take screenshots, inspite of buying the relatively more expensive version.

AnonD-547344

I did a mistake of buying Zenfone 2 for CAD 400+ including taxes. It used to become extremely hot but I ignored it. Then after 10 months of use the screen started to flicker and started having vertical stripes. I tried to use Asus Advanced Replacement program. The agent sent me information asking me to provide my credit card information to put a hold on my card. I did and they put a USD 400 hold. A day later I received an email that I should resubmit my card information as the agent was not properly trained and provided wrong information. I contacted customer service to avoid having double hold on my card, the agent told me NOT to resubmit the credit card information and ASUS will fix it on their end. For several days nothing happened with several calls to ASUS. At the end of the week, one agent investigated to resubmit my information. I did and it did work but guess what? They sent me a replacement phone which has exactly the same issue of screen flickering with vertical stripes out of the box. Really bad quality control by Asus Canada (they shipped the unit from their Markham office). Any way I sent my original phone back to remove hold on my card and contacted Asus again for issues in the replacement unit. Asus this time asked me to offer cross shipment that is I send the phone by Fedex (paid by Asus) and call customer support to provide the tracking number. Asus would send another phone before receiving the phone I sent. I did call them and provided the tracking information and Asus agent was able to verify it on Fedex website As of today, Fedex website shows that Asus have already received the unit. However they have not shipped the replacement from their side (breaking their contract). I contacted several times to Asus and each person told me a different story. The last agent told me that they will ship the unit within 48 hours and she has not seen in my case anything about the tracking information. Does this means that previous agents did nothing? And why 48 hours after receiving the unit, it was supposed to be cross shipment. Over all Very bad customer service and untrained agents at Asus based on this experience Very BAD quality control as the first replacement unit was faulty out of the box. The original unit did not worth CAD 400+ at all

Don't waste money on Asus Zenfone 2. I bought this phone (4G Ram, 16G Storage) in Hong Kong (August 2015, HKD 1999 =CAD 330). The phone was manufactured in June 2015. I was told there was a one year warranty without mentioned it only applied locally (i.e. in HK only). In May 2016, the phone kept on vibrating and warm and the battery was drained in 10 minutes. I went to Asus Computer International in Toronto and asking for repair under warranty (the phone only last for 9 months). The answer was the phone was purchased in HK and Asus Canada is not going to honour the warranty and I have to pay CAD 253 to replace the motherboard and the repair is only guarantee for 90 days. What a joke? I can buy a NEW one for less and with one year warranty. I also bought in Dec 2015 Zenfone 2 Laser in Toronto and no one mentioned the warranty is only apply in Canada. Buyer beware if you are travelling all the time in and out of the country with this phone. The battery life of Zenfone 2 is bad. For the first 4 months, it can last about 9 hours for every charges. Lately, it only last about 4 hours. I have no faith in ASUS anymore. Their products do not last because I have Asus Laptop and the hard drive did not last for 2 years and I have to replace it.

The screen lasted only 10 months and then started flickering with vertical stripes making it not usable. Search on Google results in finding that it is a common problem. Looks like Asus messed up with the screen on this phone. Very bad for CAD 400/- phone. Contacted Asus support for their Advanced Replacement Program, received an email again that Asus support person made mistakes and will be trained and I need to resubmit the request. I resubmitted it. It is already more than a week since I called Asus support for the first time and several times after that with no proper status on the case. A hold is already put on my credit card by Asus for USD 324 though. I would not suggest anyone buying this phone.

Guys, what's the normal battery consumption during sleep mode, like over the night, and/or in a super save mode? My experience so far: 20% of the battery drained during 6 hours of the night (in a super save mode). This is completely misaligned with numbers that this power saver Asus app tells (for ex., it showed me around 200h standby). And what is the usual battery consumption during a normal usage, say, several calls a day, 30m-1h facebook chatting, some photos, etc?

I have had my ZE551ML (4GB RAM, 64Gb ROM U.S. Version) for exactly 1 year now as of June 1, 2016, and I still love my phone. I know it's becoming dated and considering these benchmark at around 55,000 tops on Antutu (late model flagships are 130,000+), I am well aware there are much better devices out there now but being on a Metro PCS plan where we have to buy our own devices, for the $299 at the time, this was a great choice. It plays any game that I personally enjoy playing and has never let me down. ASUS maintains full support online including all of the latest firmware files, so if you get yourself in a bind such as I did when I forgot to unroot before running an OTA update, you don't have to worry. Just download the latest firmware.zip and sideload it over ADB and you're back in action in hardly any time at all. The UI customization options are truly amazing and many of them change things that, in the past, only Superusers could do. I think ASUS really hit the mark overall for a great mid-level phone at a price where pay as you go customers can enjoy it.
