Asus Zenfone 4 Pro ZS551KL - User Reviews

  • this phone is OTG compatible . you can find it on the official web site one of the best phone when see specification with Huawei mate 20 ( infrared stereo NFC )

  • I absolutely agree! I didn't realize I needed that for ease of connection and more solid connections with MetroPCS, and I don't want to switch carriers. Considering another phone even though I really like this phone a lot!

  • Just a heads up, this phone does NOT have an IR blaster! I have this phone and was disappointed to find out, because I only looked here, and not on the offical ASUS website. Make sure to double check specs before you buy! (Great phone otherwise, only other downside is no custom rom support... yet)

  • The Canadian version does not have a infrared blaster or built in FM radio

  • It has a ir remote, and oled display.. So better than zenfone 5

  • How's the camera and battery?

  • note: the zenfone 4 pro has an ir receiver, not a blaster.

  • This really is a killer phone missing only one proper feature that annoys me to pieces: NO VOLTE!

  • So, there is a formal review for Zenfone 5Z but no Zenfone 4 family review yet? The phone's been out almost a year!

  • No formal review yet?

  • I love this camera and screen and everything

  • Agreed

  • Both LED notification and AOD sounds useful. But for me, I prefer LED notification. AOD consumes more battery life.

  • Ilove

  • Can anyone confirm if this phone has LED notification other than the AOD? Personally, I prefer LED notification as the different colours allow me to stand from afar and determine what messages/calls I've missed. AOD requires you to come close and then see what you've missed.

  • I have the same experience

  • Seasons phone but battery drain very fast

  • The only reasons I'm going to buy this phone IR+FM

  • I love this phone. Cause not everyone likes the bezel less screen, Including me.

  • I think this phone is the best phone at the camera, a bit on the performance, but the camera I think that'll last an entire day.

  • LTE Band: 17 (800)??? B20 = 800!

  • Thanks for notifying me! I didn't understand enough. Good luck .

  • He is trying to ask why the ASUS ZenFone 4 Pro isn't released worldwide in 2018 yet, when high-end flagships this year got announced with SNAPDRAGON 845 already, which gives the fact that people will go for the high-end flagships with SNAPDRAGON 845 instead of those sporting a SNAPDRAGON 835, plus what he said about the price, u can buy a SNAPDRAGON 845 smartphone because the price is about the same as this ASUS ZenFone 4 Pro. U are giving incorrect information here, it doesn't even link to what he is saying! Please understand what the person is trying to say before typing your own dumb comment and get exposed by someone like me thank you :)

  • 62gb rom with 6g ram i think is 36k php bro and the 128 gb rom and 6gig ram its 38 to 39k php brah dang!...😁😁

  • how much it was from SM store?

  • And an IR port !!!!!!

  • How is zen ui compared to other ui's? Does it have something similar like private space (emui), second space (miui)? And adding twin apps?

  • How is zen ui compared to emui or miui? Does it have PrivateSpace/Second space? If someone can share there experiences & similarities of these ui's it would be appreciated? Thanks

  • The only FLAGSHIP Phone with a RADIO, insta worth it!!!

  • Dearest quality seekers. The best smartphone that Asus has ever built though ultra expensive !! But too much bezel,not having USB 3.1 + otg ,Bluetooth 5.1, using the notorious ugliest hybrid are somehow missing !? Nevertheless Asus is quality maker . Also upgrading and updating their best previous products is a must to prove that Asus cares too!!Possible!?Thanks gsmArena to release facts....Justice Rights loves all quality maker brands...

  • Battery drain so fast after update

  • Its already release in Philippines but only few store have a stock of Zenfone 4 pro the rest you have to order it from store...

  • Which retailer did you buy it from?

  • HM php?? Asus Zenfone Pro 4

  • This phone was already available in the philippines way way back dec of 2017. and i just bought this on the 15th of january 2018 (sm megamall) i have no complains so far. still much better than those samsung phones. cheaper but can compete

  • Dearest knowledgeable quality seeker enthusiast gsmArena followers .Undoubtedly this is one of the best Asus phablet in recent years but two things having been forgotten to offer: Radio plus rds and USB 3.1+OTG....Congratulations to HTC to win the hearts because revisions in its policy of innovation in giving better opportunities for its followers....Hopefully htc 5 will have the most superior complete qualities without any hybrids....I myself have to mention that I have Asus fonepad that everything has been stopped except its browser but I am still satisfied with it because of having the best file manager and keyboard in the high ends app qualities....that an upgrade and upgrade to higher android may solve the problems....Neverthelessthanks Asus,gsmArena and all mentioned names whom follow Justice Rights of public..,,Also besides the Asus the third in the world for smartdevice productions , Google the king is able too....Thanks gsmArena again for releasing facts....

  • Bro i know this phone is released already in Philippines but its by order wft really sucks! And its not yet in lazada ph brah...i think only 2 people have this in Philippines... because its not fully released...

  • This phone is realised! IDK what's your question about ZenFone 4 Pro. Good luck ,(and sorry for my offensive message in last answer)

  • yo! brah expect the phone with sd845 in September to October...i wonder if whe this phone will be release? maybe nxt year i think? what do u think brah?...

  • I see ZS551KL release notes that VoLTE and VoWifi have been enabled for telecoms CHT Chunghwa Telecom and Y!mobile Telecom. Is band 12 VoLTE and VoWifi enabled on the North American version for telecoms T-Mobile and AT&T??? If not, is there an ETA for when it will be enabled???

  • Hey! SD845 wasn't released when this phone announced! Don't give people useless and incorrect information! Thank you :)

  • It really makes me think if this phone is not stable or just a Test phone or have a lot of issues or what? Why this phone is not available worldwide its 2018 hello asus! Snapdragon 845 will be out soon by the time you realize to release this phone no one is going to but this anymore because they will buy a phone with 845 chipset phone instead of phone with 835 chipset...besides price of this phone is flyhigh u can buy a phone with 845 Chipset...you better think fast asus duh!...

  • A colleague brought it from a local store in Taiwan, I dont know any link of that shop

  • Bro can i have the link? And is there a SE version in that link? Samsung S9 probably got released while waiting for Asus to distribute it world wide... And is the link trustable?

  • Great Phone. All Features Are Great!

  • There are a lot of reviews on the net. Main differences between regular and pro are: Pro has dimmer screen, sharper images in daylight but noisier images in low light, and it has a telephoto lens instead of a wide angle one. IMHO the regular is more than enough for the average user.

  • The Reseller must bring ZenFone 4 Pro to Thailand.

  • Sirs: Why is this Zenfone 4 Pro not available in Thailand? Will it be available in Thailand? Please let me know. Thank you.

  • I have the Zenfone 3 Pro and have been super happy with it. I am interested in the Zenfone 4 Pro. Would appreciate any feedback on it.

  • 1.you can enable in screen buttons by activating one hand mode. 2.you can open camera by double tapping volume buttons or typing C on the screen when it's off!or using fingerprint!!

  • I own this phone as of yesterday, imported from Taiwan. They go for about 520EUR (local Taiwan) for a 64GB model. I'm just gonna list the bad points (for me) about the ZenUI 4.0 (android 7.1.1) OS that comes preinstalled from ASUS. - NO on screen buttons (not present in Settings-> Accessibility), you have to keep using the capacitive buttons on the border of the screen. There is no option to enable it unless you download an app or root your phone. - NO multiple android users profile that you can create. There seem no way to unable this, unless you change ROM. - NOT possible to activate the camera while double tapping power button. - NOT possible to skip track if you draw > on the screen, when it is turned off.

  • ZenFone 4 Pro SE:Special edition :6GB Ram + 128GB Rom. ZenFone 4 Pro : 64GB Rom + 4GB RAM.

  • what is the difference in between ZS551KL SE and ZS551KL?

  • It’s the first phone on the market to come with Wi-Fi ad standard, add to the specs please.

  • I will test it in at least 3 months later xD I will buy this phone,just wait. The camera is awesome,SD835,6GB LPDDR4x,AMOLED FHD,Selfie is pretty good(with F/1.9,EIS,8MP res),NMT unibody,2x optical zoom , ASUS Super Pixel Engine,It's speakers,audio output,...... Really Great Phone.

  • i don't know bro but and i don't understand why i really don't like Samsung phones but i do like there SD card Even though it expensive...

  • Yup, wait for S9 better, very soon.

  • What's taking them so long to release the phone...its kinda sucks when u buy this phone after few months new phone will be release with 845 chips or 855 right? So i im really thinking if ill buy this phone or wait for the phone with 845 or snapdragon 855 chips...

  • Where can I buy this phone ? I'm in the UK .

  • The phone not in market yet, normally ASUS is like that.

  • what the f ck this phone is not yet release in the Philippines the year 2018 is near and yet now asus zenfone 4 pro I've been waiting for this phone to be release in the Philippines jezzus what taking you so long asus...

  • Try "BlueMail", it's a great app, complete with multiple mail, calendar and task functionality. You'll love it!!

  • i just contacted asus support asking about the ir sensor. they said its a normal inferred sensor that can send and recive ir signals, and should work with, say, a universal remote app. Can someone else test this and provide more confirmation if the ir sensor works?

  • It is unfortunate that Gmail is the only decent option. I do not like Gmail that keeps showing the same mails over and over even if those mails have been deleted. It might be a coincidence that those mails are in general ads.

  • They use to make great and affordable phones. I got one Zenfone 2 for 299$ with intel chipset almost 3 years ago and it still rocks at every level. This one rocks too but not for 850 EURO.

  • No it does not

  • I concern about MP, image quality and low light, just hoping that there will be a CM2 in the future. Not going to get any Asus anymore, their ZF3 was supposed to be "built for photography" and its camera never focus properly.

  • does it have a IR blaster?

  • I got mine on 11/24/17 and so far I love it. The battery life is pretty good. I have had it off the charger for 5 hours now, and I am at 69%. That's with me listening to music, playing a game on the bus ride into work. The screen colors are vivid, my eyes had to get used to them. The camera is great. I had friends comment on how clear the pictures I took with it are. The only problem I have is the lack of ambient display, which is something I loved on my OnePlus 2.

  • Even it only 12MP, it has newer sensor, bigger aperture and more features like Dual-Pixel PDAF that Zenfone 3 Deluxe doesn't have. Camera on HTC One is outdated, 4MP is only for selfie camera, while 12MP is good enough for main camera. If you really concern about MP, get yourself Zenfone 3 Deluxe and expect good low-light on it. Dream on!

  • Got it, love it.

  • So I received mine 4 days ago and love it. Battery lasts well over a day, screen is good in daylight, have not done a camera test yet but initially it looks good. Speed is great and overall I like it. Only thing is that it does not have a native email app, other than the Gmail one. Trialing a few at the moment.

  • LED? Children's eyes? Whatcha talkin bout Willis? Don't stare at the sun.

  • what led protect children's eyes

  • If MP don't mean nothing, then why did the HTC One flopped...?

  • so you have this phone ? how do you rate battery life ? strange no reviews about this phone yet and nothing here on gsmarena about endurance rating

  • smaller MP means bigger pixels 1.4um for better photos in low light. MP don't mean nothing.

  • The phone i have Infrared Sensor Not Infrared Port... Remote Control not working.

  • i would be happy to pay that price if it was IP67

  • I have a request from GSMARENA. Can we get a full review on the ASUS ZenFone 4 Pro ? It would be very nice to see the camera quality of this cell phone. Especially, photo shoot at nights, during sun rise, evening, and sunset. Also, a few selfie during day and night. Thank you.

  • Hi everyone . I'm in Iran. how I can buy this cellphone (zenfone 4 pro) ? please Help me. thanks.

  • has anyone tested the IR port of this device, can it be used as a remote control for TV an audio equipment?. The description says IR sensor, so i guess it can be used as a remote control.........

  • No

  • So has anyone got one of these and would you recommend getting one?

  • The crap software can be changed. Asus has 4 soft versions (SKUs - Stock Keeping Unit): WW Global TW Taiwan CN China CHT Taiwan, ChungHwa Telecom I bought 4 Zenfones, 1 with CN soft, 2 with TW soft and 1 with CHT soft. Two of them were Zenfone 2 and 2 were Zenfone 3. I've changed them all to WW Global SKU. No problems so far. The change is difficult, but I used to fix electronics for a living. Asus Zenfones are the best cellphones I have used. I refused to change my every day Zenfone 2 when my lid broke after a huge metal knock, and I couldn't get the repair part in my country, I waited 2 months for the LCD to get here, and I haven't changed the lid yet, but I am still using the device. The battery lasts 2 full days with heavy use. It is a rock. The Zenfone 3 is even better, but I prefer the Zenfone 2 for every day, if someone steals it from me it would not be a big issue.

  • Your wife is a wise woman, keep her.

  • Can that Infrared port be used as a remote control? Thx.

  • That is wrong, it is actually an infrared blaster for camera thingy, not infrared sensor.

  • The specifications say that it as an infrared sensor. Is it true?

  • Yeah better to wait. There is still no review of Zenfone 4 Pro right now on YouTube but there is a Zenfone 4 MAX Pro, its has same UI (ZenUI 4.0) So you can learn about ZenUI 4.0 little bit. (ASUS says they throw much bloatware on ZenUI 4.0) By The Way, ASUS updating their Zenfone 4 Pro's website with Heart rate sensor on Home button.

  • Hi Radare, "can You have the phone" ,are you talking about the zenphone 4 PRO?, that's the one I'm interested in, if so ,how is the camera and audio (so far), those 2 features are most Important to me.

  • I just came from Taiwan, I could have bought it, but everyone (family from my wife!) told me not to do it because crappy software . I'm waiting for a full review from this website though, I have not given up just yet. Besides, in the next couple months a lot of interesting new stuff coming out, not least the new Nokia 9 , plus that I'm probably in Taiwan again next year.

  • i am using the phone, i want to answer to the pal who is complaining about his zenfone 2. in this phone, you can use double sim card but when you insert the 2nd sim card you can not insert memory card but phone's memory options are quite fine. and you can easily choose the primary sim card from options menu and you can use only the primary sim card's cellular data. and if you want to use the other sim card's data, you just choose it from options menu and it is done. i like the phone, there are better phones in the market but not for this price. it is fast with 6gb ram, has a perfect finger print reader, neat and fast. asus developed its own app lock and talk record apps which is fine. i strongly recommend the phone if you have limited money to buy a phone

  • where to buy this phone ?? USA/India

  • Wow I'm impressed with Asus phones specs to cost ratio. I'm a little concerned on how/why they are able to do this? If everything is good than this phone is definitely underrated because I don't hear much about it.

  • Dual sim. ok is it same with data connection? because my asus zen2. 1 sim have data connection. cannot switch data like other phones. so every time I internet i'm still removing the sim 1.

  • "...there's no reason to not try it." A reminder: Do or do not. There is no try.

  • The price in Taiwan is NTD 18990 or €532/$629

  • If this one delivers on the camera ,(as advertised and promised), and has a nice score with audio as well, this could be my next phone, but those are two "ifs", and then of course there's price. It looks promising though, keeping fingers crossed, I'm actually waiting for a full review on this site for the pro model.

  • I see the wifi specs not only 802.11 AC, but 802.11 AD...

  • Impressive specs, but it all comes down to cost. Its design is severely lacking, it reminds me of the Pixel 1 in the front. As far as name recognition and proven ability in the phone market space, I would say they are behind OnePlus. Honestly, I see no difference in ZF4Pro and the OP5, except connectivity speed. If they price it competitively in the US, they may get a shot at the reigning champ of the "cheaper" phones.

  • Impressive specs under the hood, would have preferred to see a WQHD bezelless display, but the 1080p display with that massive 3,600 mAh battery should maximize battery life. All in all, not a bad phone.

  • ASUS makes better Computers than both. They are Computer Giants.

  • Your company is not so big as Apple or Samsung that you overpriced your overrated phones

  • Agreed

  • Xiaomi Mi6 have like to say same specs as this think and cost half of the money. This offers nothing worth 850 eur apart from procesor and graphic card. Rest of the specs wont make a hole on earth for 850 not even tiny one for a golf players.

  • No water resistance at this price? Woah, you've gotta be kidding me!

  • Shit phone company asus ?, RIP asus? do you know annual asus profit?.

  • Wow..... A sh*t phone company competing with the big boy..... rip

  • Asus is completely crazy! For this price i Will look elsewhere! 700€ should have been their goal. Not even a 2k display is provided...come on... This will be a huge fail! RIP Asus

  • Asus is the only one who don't forget to include much needed fm radio..

  • for this price you can buy real smatonfone - Google Pixel.

  • Does it have Quick Charge? Proper Quick Charge? It is reported that the Zenfone 3 Deluxe only charge quickly with the original cable and charger. That is not true QC specs.

  • The problem happens after an OTA update, how can it not be the software???

  • I got the same problem. However, the problem is not with the software. It's with the camera's component. You can bring it to Asus Service Center and if you still have the warranty, they will change your camera's sensor with a new one. I know its not the software problem, because i have a friend using the same phone, the same software and the same update. But, only my camera are unfocused.

  • The ZF2 is not supported anymore because it's years old. They are focusing on the current gen. As for the ZF3 nougat issue, I assume they learned from their mistakes. ZenFone 4 line up is amazing, there's no reason to not try it.

  • Better if it works properly. However Asus have idiots writing their software thus their phones never work properly. Everytime there is an update, there will be a flood of bugs.

  • Don't buy asus, their software support is the worst, they tend to release phone as it is, i mean buggy. And they are veeery slow releasing fixes and updates. Also note that they completely abandoned zf2 users and they disappointed zf3 users with their nougat update disaster. Asus is not reliable...

  • VoLTE support is dependent on your carrier. Most phone out past couple of years all have VoLTE. I don't know any phone that doesn't have notification light.

  • Agree.. But Remember, OnePlus's Android System is up to date for real

  • Pretty similiar to the oneplus 5 spec sheets But it has microSD slot Wideangle camera with OIS Dual speakers (stereo like) FM radio And a 3600mah battery ---- If it comes for 600euros, it's a pretty good deal since the oneplus 5 comes for 499euros. If it comes for more than 600euros it isn't worth it since Asus is known to not update their phones, and the awfull customer service, yup, worse than oneplus.

  • It does not support VOLTE band in India

  • Update is to worse in Asus phones

  • Does it have LED indicator / notification? Does it support VoLTE?

  • Asus phones will only last until their first update, then it goes downhill from then on.

  • Good hardware that will be broken by the usual Asus screwups with the software. They broke the cameras, charging, etc of previous Zenfones and refused to fix. Every updates brings new problems making the phones useless. Take the Zenfone 3 for example, Asus claim that it was "built for photography" but then they updated the phone and the only photograph it produces are unfocused ones. Not sure what photography they do in Asus, but I do not like unfocused photographs!

  • Increase battery please

  • Clearly, nothing new in every phone have screen have battery have camera have sensors and it doesn't last a lifetime, no matter what brand it is , it still have the same name, its a PHONE. :D

  • increase battery to 5000mah

  • Okay that's great to hear

  • Never

  • I prefer Lenovo P2 with its 5100 mAh battery

  • when will asus zenfone 4 realese

  • nice

  • Yes you telling right. Zenfone 2 has good pricing but zenfone 3 has mad pricing. At time of launch price was 28000 in indian rupee. Now at 16500 rupees. This is unjustis with who bought zenfone 3.

  • Please add check quality camera

  • I'm not a fan of asus since i use zenfone 5 then i use zenfone 2 and now i'm using zenfone 3 max 5.5inch.. A bit dissapointed on asus which the network coverage pretty weak and not so stable inside the building. But overall asus is good for me and i must get the zenfone 4 for more advance experience.. Asus customer service is much more better than any others, so stop complaining something u dont know.. I guess this zenfone 4 is my desire phone after all with full perfect spec that i needed the most..

  • this has a IPXX certification right? considering the batter is not user replaceable??

  • Yes ,You're Correct and it is a Li-Ion Battery not a Cheap Li-Po Battery

  • whaha ... zen 4 pro has the Biggest Battery on a proper Flagship with SnapDragon 835 except Samsung G s8 Active(Carrier Special Edition Only)and not yet official.. ZENFONE 4 Pro - 3600mAh S8+ - 3500mAh Mi 6 - 3350mAH Oneplus 5 - 3300mAh LG V30 - 3300mAh Samsung Galaxy Note8 - 3300mAh Sony Xperia XZ Premium-3230mAh ZTE nubia Z17 - 3200mAh Nokia 8 - 3090mAh Essential PH-1 - 3040mAh HTC U11 - 3000mAh Motorola Moto Z2 Force - 2730mAh Sony Xperia XZ1 - 2700mAh So Don't be Disappointed .. Be Educated ..^_^ wahah ..

  • For your Information, Zenfone 4 Pro use 2 flagship cameras. Sony IMX 362 same as HTC U11's cam (which is has big Sensor and Pixel Size) for Main Camera and Sony IMX 351 same as LG V30's cam (PDAF support) for 2X Zoom Camera PLUS advanced features like OIS,EIS,secondary ISP (ASUS SuperPixel), 2nd L-AF,Dual Pixel PDAF main cam,Color Sensor, RAW support and ultimate Manual Mode cam. Learn more at Zenfone 4 Pro official website. *Based on this vid, Zenfone 4 Pro beating Note 8 camera, some people dont believe it even the intro is Zenfone 4 Pro and Note 8 picture.

  • Just inform me when it's on market I like it for the infrared port and the ram 6gb

  • Batteryyyyyyyyyyyyyyy 3600 from Zenphone, disappointing

  • Zenfone 4 pro is on par with Note 8. Its main rear cam has 83° fov with 1.4µm pixels much more better than LG V30's 71° fov with only 1.0 µm pixel size. F1.7 and F1.69 basically no difference.

  • nope..you can download manually for marshmallow on the Asus website..no OTA update

  • Please making photo quality!

  • True, technical supports for my previous Zenfone 2 until Lollipop and it doesn't see any further efforts then.

  • I would not recommend any Asus phones, not because of the hardware that works, but because of the poor technical support it has. Asus has no problem in leaving the users on the street. I have a Zenfone 2, which no longer has support of any kind and the worst thing is that they do not fix the errors that it has.

  • Where could one buy Asus phones? Please reply.

  • I was going to just give up on getting a phone that has all the features that I'm looking for and just get a Oneplus 5, but this phone looks really good! Hardware keys, 5.5" screen, Snapdragon 835, sd card slot, 64gb storage, 6gb ram, stereo speakers, headphone jack, frickin ir blaster and radio (!), usb type c, fingerprint sensor, 3600mAH battery, that is a really good looking spec sheet. If this phone gets ip57 or better waterproof rating and gets rooted then I am definitely getting it

  • Good opinion :)

  • Agreed.

  • Dearest Hari. However I can't write well because of my touch problems, I thanks you first for reading my opinion !Also please mention my English mistakes to correct myself!!However GSMArena is fact-writing fact-following entity for everyone everywhere in the world to solve their problems through understanding language !! Also suggestions are better than a bad defense of a brand awkwardly !!! Thanks against to read my opinion again and thanks GSMArena letting freedom of speech based on moral guidelines.... Justice Rights.Omid12Omidvar just sees but not looks...my teacher !!!

  • Oh Omid, Please improve your English. Asus gives an excellent smartphones with reasonable price tag. Zenfone 4 Pro is better than Samsung galaxy s8 plus and Note 8 and also better than LG V30.

  • Cmon, isnt Zenfone 2 era and ASUS is maturing themsleves faster than "you know". Even Zenfone 3 get Android 7 faster than their 2016's phones. And blame the Intel, theyre stopping production of Intel Atom Z series not ASUS. Then, how about X****a M5? Its has same release age of Zenfone 2,64 Bit SoC and MEDIATEK still exist then why no Android 7 update for it? Android 8 isnt rumor, ASUS announcing it on Zenfone 4 series release in Taiwan so Zenfone 3 will get Android 8 with ZenUI 4 on Q1/Q2 2018. Check Zenfone 4 Pro hands on/review on YouTube and hope GSMArena can review it. They say Zenfone 4 Pro has backlight key. I dont know about 4K HDR but seems like it has very big memory size,drain battery faster and very limited content. FHD + AMOLED its enough for everyone. (Even HD + IPS)

  • your named price is not even close HAHAHAH

  • Piece of junk with screen resolution, backlit "back" key probably missing, and the same like with ZenFone2 ZE551ml the updates and new android will come just in rumours otherwise you are still on shit that is capable android 8.0 but it won't get it so why buy it? Asus never ever again. Plus ghost touch plus cheap plastic...not worth buying I rather give 200 eur more for better phone 4K HDR capable etc.

  • Without water protection again? Nice device, but the same weakness as ZF3: few drops of water can kill it.

  • It cost around 40-50k php? I rather buy an iphone 8 plus or iphone 7 plus(2nd hand) spec wise and money wise, sorry not a fanboy with the two platforms so no bias

  • My dearest GSMArena enthusiast. You are welcome wholeheartedly+ .

  • Nice Opinion! Afarin :)

  • Dearest Asus. You usually make the high quality smartdevices that last more that usual expectations ! This is a high end carefully made smartphone device ! But using the least bezel and using USB V 3.1 and mentioning otg , undoubtedly will have put this phablet to much more high ends + eradication of unpopular hybrids !!! Justice Rights.Omid12Omidvar loves all brands and my writing is merely suggestions and never every destruction criticisms....Thanks GSMArena to release unbiased neutral opinions....

  • I'm tempted but I'm not exactly careful with my phone, always banging my ZenFone 2 about. Why they have to cover it in glass...

  • Hi, I don't if this will help but I post it anyway. I would say for the current version of software, it might have aptx, since the older Zenfone devices have one. Have a look here "https://www.aptx.com/products?field_aptx_type_t­id=482&field_product_category_tid=All&fi­eld_product_brand_tid=194". Keep in mind that some devices are supported but somehow they are not in the list, like Xperia Z5. However, you can wait until Android O update, if it does happen, since Android O support AptX, AptX and even LDAC for mdr1000x. Ps. please pardon my English.

  • Dear asus i love u, but please write ur NAME BRANDING On front of mobile.. otherwise u look like value less.

  • I want to buy hi-fi headset with this phone (bose qc35 or sony mdr100x). But in the specs no apt-x support defined! :( Is there a technology for hi-fi music transmission in this phone? Please help.

  • Unfortunately, I don't think this phone has an IR blaster. Source - Official site "https://www.asus.com/us/Phone/ZenFone-4-Pro-ZS5­51KL/Tech-Specs/". Even though the design is boring, the phone still has interesting spec - basically one plus 5 with hardware navigation, native stereo speakers, OIS, larger aperture and pixel size, radio, and a lovely micro sd slot. The software department would be inferior to one plus 5 though.

  • if battery is 4000 it will be emperor of segment (don't forget the price should be acceptable to common man ) and easily wins peoples heart behind pocket

  • Gsmarena says it has infrared in the preliminary specs. Gsmarena could be wrong though.

  • Perfect phone except for display, AMOLED screens hurt my eyes :(

  • Ya its so expensive, I think Zenfone 4 is okay with great specs too and much more cheaper...

  • If this phone is priced at 40 to 50 thousand Php then I should say Asus will soon lose it's name in the mobile device industry. They started right with the Asus Zenfone 5 and 6, they made nice devices with great price tags then after 3 yrs they're going a different path? As in more expensive than Sony, Samsung, LG, HTC or Huawei? Asus does not have a big name yet when it comes to mobile devices, they're just starting! They should price this at around 32k. It's not even a QHD phone. The only top feature that it has is the Snapdragon 835.

  • Do you know this is also 1 of the most expensive SD835 phone in the market?

  • Nice

  • i heard this phone zenfone 4 cost around 40k to 50k here in the philippines, i know it has good specs but would you rather decrease the price (reasonable price) so that it will be price friendly for us filipinos.

  • How long until its avalable for sale in EU? Whats the expected price in EUR?

  • i love this phone. it functional as a phone must & blazing fast, not selling gimmicks like edge screen or super slow motion cam. good at performance, camera, sound & battery life. superb phone

  • Based on this vid, Zenfone 4 Pro has waterproof body and heat pipe system.

  • It has very good camera also. It has the latest Sony. It can even compete with high end DSLR camera.

  • Damn i wanted to love this phone, but why don't they keep the 5000mah battery from the zenfone 3 zoom? Why do i always have to choose between battery life or flagship specs? It annoys me a lot

  • Damn, the first time ASUS have created a real monster. But how does it stack up to current flagship competitors? A advantage for them is the FM RADIO, which I have never seen on a flagship for a long time now, but the disadvantage is the lack of IP rating for dust and water resistance. But pricing is to be noted for. 599USD is pretty competitive regarding the specs. Really hope they really step up the game in the camera too

  • its good phone ...Monster mid range chip SD 630 ...10% faster from previous 625.Bluetooth 5, Quick charge 4 which is 15 min 50% charge...and if u want parformence based phone then this is good choice for u...if u loved to take pic then go with moto g5 plus or uocomming moto X4 ...or flagship phones ...all mid range phone have some good and bad side ...u have to choice wt u want

  • It does not have infrared wrong information!

  • I don't think they have a IR blaster....are u sure....??

  • Samsunish but nice phone actually

  • Hope the next zenfone series will not disable fm radio

  • I must congratulate Asus for coming up with this phone. It isn't perfect but it has three (3) unique selling points other flagship snapdragon 835 phones from Oneplus, LG, Pixel and Samsung DO NOT HAVE. 1. It is the only snapdragon 835 phone with IR blaster (very rare)! 2. It is the only snapdragon 835 phone with FM radio (very rare)! 3. It is the only snapdragon 835 phone with a sizable 3600mAh battery (rare)! This is the second largest battery among snapdragon 835 phones announced so far (next to the S8 active's 4000mAh). Coupled with a modest 1080p display, it should be the LONGEST LASTING snapdragon 835 phone in existence and will probably score very high if not the highest in benchmark tests. This is in addition to the usual, very common flagship features: dual cameras, sd card, dual sim, 4k video, OIS, 3.5mm jack, USB C. Hopefully it also comes with slimport support. I just wish though a variant of the Zenfone 4 PRO is released with bigger (5000mAh+) battery and bigger (6.0"+) screen in the same 16:9 aspect ratio with no curved glass edges like in the S8+.

  • I saw in one video on youtube that Zenfone 4 pro has an FM radio (2nd notofication screen) what is great. Ordinary Zenfone 4 either.

  • Do not use the word "pro" because asus phone is not a pro is ancient models

  • It was too late,old-fashioned Asus can only make old stuff

  • Asus usually don't disable Fm radio. In Iphone could also be radio, but it is disabled.

  • But is a flagship phone not a mid range or low range

  • Of course, companies are shutting doown fm radio, because they wants you to use Internet Radio, which is not for free(unless you have Wireless connection).

  • After samsung remove their ir blaster, now many phone from china manufactur use it. Hahahah.

  • the number of pixels is not always the basis of a good camera. remember that. do some research bro

  • ASUS moving Zenfone 3 FP sensor on back body to front body of Zenfone 4, Glow effect like on Zenfone 3, Dual Cam based place based Zenfone Zoom S. (Ya maybe ASUS should be place back camera to center back body so no more copycat but still haters will say "weird replacement camera".),side metal body based Zenfone 3 and FYI, Even Nokia 8 is looks like Lenovo Phab 2 Pro. So it should not suprising.

  • Don't forget that this phone has the exact specs as OP5 lol. SD835, no IP certified & FHD amoled display.

  • That is asus ish!

  • The most important thing is new ZenUI 4.0, which the company says is simpler, more intuitive, as well as "modern and gorgeous".

  • iPhone-ish back with Samsung-ish front? I don't see any Asus-ish thing with this ZenFone, LoL

  • Still have fm radio for SD835?

  • looks sexy

  • Finally, a good looking smart phone from Asus! Well done! I hope though, the next one will be smaller. :)

  • I am on the market for a new phone right now. I need a dual sim, however here in Canada, dual sims are not available much. Most are imports with no warranty. I can however get Zenfone 3 at Best Buy, Staples or Memory Express. My top contenders right now are Galaxy S8, LG G6, Xperia XZ Premium, But like I said, all are black imports with no Canadian Warranty. When I saw that Zenfone 4 Pro is supposed to come with the Snapdragon 835 I got excited. I really want an IP rated phone. So let's see if Zenfone 4 will have that and what the price point in Canada will be. Currently Zenfone 3 will be $429. The LGG6 import will be $580. S8 import is $780.

  • Pixels don't mean performance. #BecauseIts2017

  • Another people with weak knowledgement about the camera here. Even this phone has 12MP camera, it uses newer Sony Exmor RS sensor, so don't think 12MP camera can't make good photos and guess what? Zenfone 3 Zoom with 12MP camera is far better than your 23MP on your Zenfone 3 Deluxe.

  • I thought the same thing. If the specs on this phone correct, this would make Assus Zenfone 4 the most crappiest phone of 2018

  • is this model support OTG ? i really need OTG for my work so i can check on data from usb when i'm outside the office, from all previous model of zenfone that i dislike is that none of the all zenfone model support OTG & NFC at all.

  • WTF 12MP????? my Zenfone 3 Deluxe is 23MP

  • Should stick to making motherboards

  • What's wrong? The pricing, the build quality that u don't even believe it have plastic frame, and the fact that so less people buy ASUS and the price they are demanding is very high

  • But what I said is true, is just that u don't want to accept the fact

  • I Still using my zenfone 2 Since 2015, my friends with Crapmsung have to change their phones at least 2 times in 2 years because the performance is really trash.

  • Nice Opinion ;)

  • If you don't want to become reported stop talking offensive.

  • Don't talk about that Samsung here. Very high strength and very high build quality with good specifications. What's Wrong?!

  • So u rather buy a lower quality build smartphone than a high quality build smartphone like GALAXY S8? Good luck to your smartphone after wasting the money on this if it is released because there is more chance of getting bend.

  • Emm so u want a fake all metal smartphone that is being bend u call that good and special? There's something wrong about your brain man

  • Yes.i watched that. That was good. And special.

  • Judging by what they did on Zenfone AR I won't be surprised that they would release a new Zenfone 4 AR with this phone with a humungous 10-12 GB RAM, anyway this phone would be great too if only they price it right.

  • Maybe this phone will similliar of HTC U11.

  • Since a leak from Italy did indeed confirm the phone will instead have a 4K display, why don't you change the specs for the display to 1440 x 2560?

  • Lol no problem dude the evidence is already shown in JerryRigEverything for ASUS ZenFone 3 Deluxe durability test XD

  • Asus didn't make lies,asus doesn't make lies,asus will not make lies.

  • Agreed.

  • Asus zenfone AR is the first mobile phone with 8 gig ram, if you dont know so raise up your information and then start to talking. After that i didnt say any thing about phone config dear twatonk, asus is going to stablish new revolution in phone world, you will see in future be sure

  • It is going to be another expensive smartphone from ASUS, as always. Like the ASUS ZenFone 3 Deluxe, JerryRigEverything revealed their "All Metal Design". ASUS makes lies, their phone are not as durable as current flagships, bend so easily. I am sure they will promote this smartphone as another "All Metal Design". See what happens when Zack expose it again next time

  • But hes right Asus was here first with 8 and 6gb ram phones. This one is really something special.

  • Nothing special.

  • Calm down tiger and read better Twatonk's original statement.

  • Asus built first 8 and 6 Gb ram in thw world.ZenFone AR and ZenFone 3 deluxe.

  • Special phone from asus. 8 GB ram was first in ZenFone AR not in oneplus 5!!

  • the new is you have so many brands and so many prices and so many designs and the most important is the concurrency between those brands and the consumer is the winner at final because every company want sale the most of his phones and for that he need to reduce the price.

  • Clearly nothing NEW in this phone, Super AMOLED in Samsung, 8GB RAM in OnePlus, and almost every flagship this year using Snap835, whats new?

  • Asus began the new era in phone world.
