  • I'm excited to have this ZenFone 3s max because the performance is unique.ASUS ZenFone 3s max 2 days checked everything I cannot.find nfc support so sad.😥

  • My Asus ZenFone 3s max hangs very frequently. I have removed all the unwanted apps but still there is no change. Pls suggest me something. Camera quality, sound quality, everything thing is good but the software performance is very bad!

  • Umm.. Maybe it just happen on mine. The latest might work well

  • really? im actually planning to buy one

  • Recommended. But it will heat like a frying pan while multitasking on games.. 🐈

  • Does it have 4G for data connection?

  • please improve your manners

  • Ummm.. Ever heard wristwatch..?

  • Is this phone really have 802.11ac wi-fi connectivity? Cause I just bought it and couldn't find any 5ghz wifi. I need confirmation regarding this issue. Thanks.

  • Pliz improve your English. .

  • Setting no schedule power on/off ! If we travel on business, the phone we set alarm morning 8am wake up n then switch off phone!!! In morning my business all gone!! Wont ring!!! Or sound!!! This stupid firmware who program? Asus! Stupid programmer....! Should think to all buyer, this schedule on/off is very useful n should have!!! Should we travel have to bring a giant clock n heavy.......funny asus maker! Other phone all have!!!

  • very good phone excelent nice one

  • Yes, you can use external memory and use 64GB memory and put it on your cell phone

  • Same like my Asus phone

  • wrost sound effects & internal MIC problems... i've checked others phone also. same MIC problem

  • Why my asus zenfone 3s max have no brand name in front of the phone?just like other have brand name..

  • Hi Prasanta, Run SMMI test. If the test is failed, visit the service center.

  • Hi Ranjan, Follow the below steps: 1. Lower screen brightness An overly bright screen consumes more power and can be harmful to the eye. To adjust brightness, swipe down from the notification bar twice and use the slider. Extend your battery life, and protect your eyes while doing so! 2. Shorten screen timeout time. To squeeze more juice out of your battery, you can shorten the screen timeout time so that your phone goes into sleep mode faster. Try changing the time from the default 1 minute to 15 seconds. To change this setting, tap Settings > Display > Sleep. To change Cover View screen timeout time, go to Settings > ASUS Cover > Automatic sleep. 3. Trim unnecessary background apps. Prevent unnecessary apps you don't need from running in the background and consuming your battery by using Auto-start Manager. Tap Auto-start Manager to select apps you want to discontinue from running. 4. Use Smart-saving Mode . ZenFone 2 has many extremely useful battery modes, one of which is Smart-saving mode. It provides extra toggles for brightness, a feature that turns off internet, and an Extend Standby feature that lowers battery consumption by efficiently managing your push notifications when your phone is in sleep mode. Tap Settings > Power management > Power Saver > Battery Modes > Smart-saving mode. 5. Tap Boost from Quick Settings. Have you ever wished for a single button that solves all your problems? When you tap Boost, not only does it make your phone faster, but it also lowers battery consumption. Swipe down from the notification bar twice to find the Boost button. 6. Choose Wi-Fi over 3G/4G Data. Using Wi-Fi instead of a data connection will use less battery because your phone doesn't need to constantly search for the network. To turn on Wi-Fi, swipe down from the notification bar twice and tap the Wi-Fi icon. 7. Turn off Location Services, Bluetooth, and NFC. Don't be lazy! Turning off these services when you're not using them can extend your battery life. To turn these services off, swipe down from the notification bar twice and tap the Location, Bluetooth, or NFC icon. 8. Set up an Auto-switch mode schedule. You can't be using your phone all the time! Set up a time interval in Auto-switch mode to automatically switch to a lower battery consumption power mode when you're not using it. To do this, tap Settings > Power management > Power Saver > Auto-switch mode. After enabling this feature and choosing your starting and ending times, we recommend setting it to change to Ultra-saving mode (the default).

  • Hi Anonymous, Slight heating is normal. If the device is heating abnormally, visit the service center asap.

  • Hi Chinu, Please follow steps below for troubleshooting: 1. Perform Boost: Slide down the screen from upper area to access Quick settings and then tap Boost. 2. Uninstall apps that are not often used: Settings > Apps > (select an app) Uninstall. 3. Clear cache of apps: Settings > Apps > select apps that may cause malfunction > Clear cache. 4. Launch Play Store and update all apps. 5. Reboot your phone. 6. Update firmware to latest version: Settings > About > System update > Check Update. 7. Access Safe Mode by long pressing power key > tapping and holding Power Off > tapping OK. If your phone works well in Safe Mode, there may be some 3rd apps that cause malfunction. Please reboot your phone and check again if it works well. 8. Backup your data and perform factory data reset.

  • No

  • My asus 3s max hang and data speed low..plz tell me how solve my problem????

  • No

  • is zenfone 3s max memory expandable to 64GB?

  • Yesterday [6/01/2017] Only, I have bought asus zenfone 3s max mobile phone today one side touch is not working, unfortunately i put my sim in this mobile phone, and i complained to the customer Care they are not giving proper response so please don't purchase any mobiles in asus company itz my suggestion, my friend also have many issues in this company now only i came to know....

  • Hi, I bought zenfone 3s max on 15/09/2017 and in just 3 months my phone started creating problems. First It seems that battery backup is too good but now it just take 12 hours to drain the whole battery. After 10% it just takes 5-10 mins to turn off the phn. Phone started hanging apps closed automatically. But the worst part is recently my phone screen got broken on slight fall even after there is a screen guard on it. And when I went to customer service centre for screen replacement they asked me for Rs 4100/- even my phone was in warranty period saying that we will not give free replacement for broken screen. And when I said that it is too costly as the phone price is rs 11000 and 4100 is not worthy, I will replace it from grey market at only rs 1500/- you just see other problems as it comes under warranty like battery and phn hanging problems. But they refused to do so. You first have to replace our screen and that too under company service centre by paying 4100/- rs . This is our company policy. Means you dont have any other option to go . This is how this company make fool of customers. I just asked the company representative that why you didnt tell you shopkeepers selling Asus phone that they should tell the customers about this company policy at the time of selling phones but he just said that sorry we cant do that. And when I argued him then he said that just go and just talk to shopkeeper from where you purchased this phone. I request all that pls dont buy any of the Asus phone otherwise you will also trapped in this worst policies of this worst companies. ...

  • Asus is giving a different model in the box of Asus 3S Max. Phone supplied is Asus X00GD which is an older 2016 model and with Ext. memory upto 128 GB. The 3S Max is a 2017 model with ext. memory upto 2 TB.

  • i disagree with you. i bought my asus phone and used 1 year already still perform well for battery. not to back up asus phone, but your statement is totally personal opinion. cannot jump into conclusion like this. i used sony, samsung, lenovo. and i made many comparison. so, i knew which one is better.

  • Never buy an Asus phone!!! You'll regret ever getting this even if they put 10000mah it'll still be junk!!!

  • I Purchased Zenfone 3S Max its just 40 days old phone and started hanging & operating touch screen itself i concerned service center they accepted that there is Touch screen & mother board issue.is the Hardware parts of this phone are Durable?

  • i have this phone for 2 weeks ,everything is good except two things compared to ma old lenovo s660: 1.voice clarity in call voice is bad..in 4G is terrible... 2. baterry-drains too fast.i expect more than 5000mah battery..in normal use it takes down 50% for a day in normal usage:not more than 15 min talks in a day,and not more than 10 min using viber and wattsap so i'm disapointed if anybody have solved these two problems pls help me

  • There is a problem with the firmware in the latest release for this phone. I have noticed if you have an app running for a long time and don't use the screen or controls (such as watching a 45+ minute video on youtube with the phone lying still on a table) it appears that all the input circuits get turned off (touchscreen, up/down volume, fingerprint reader). To resolve you must hold down the power button or power+down volume button until the phone turns off. When you restart the phone everything is fine. COME ON ASUS - GET THIS FIXED!!! The fact that they recruit users to sign-up for their beta software program to help report bugs and troubleshoot the phone tells me they are going cheap on hiring staff to do adequate testing.

  • Yes, it's available. Go to Glorietta. I saw it in a few stores there.

  • that's call ghost touch, most of Asus phone became like that. The solution is u must replace touchscreen. I don't like Asus phone because that.

  • ma'am or sir? yes deny all of the apps on your phone so that it will not automatically set or work.

  • im a ma'am. I haven't yet seen the model of this phone maybe its not available but the asus zenfone 3 zoom is already release in the Philippines, but I think by the end of this month it will be available in our country. :)

  • One problem of my phone that is display apps automatically clicked, camera automatically photo captured and video automatically jumped,vol high and slow, video jumped to another video. Pls tell me how to solve it

  • im from philippines i just want to ask if there is zenfone 3s Max now in the philippines my last visit in mall of asia is yesterday may 23 2017 so righ now i dont know if when will be available .. please help me zenfone 3s max is my 1 fisrt choice since my samsung is stealed on me TIA xD

  • hello sir im from philippines to and i want to know if there is available now in the philippines ... asus zenfone 3s max is my choice tnx .. may 23 2017 i visit in mall of asia there is no 3s max

  • I have the previous version of this phone, and I was satisfied of that since it is fast charging and good to use for about 2 days. it is also good for gaming since the RAM is 3gb.

  • there is no gorilla glass in zenfone 3s max

  • If i remember it right the previous "Max" is also 5000 mAh without fast charging. It took at least 4 hour to charge.

  • Must be a mistake. Who in their right mind would offer such a big battery without fast charging. Pointless.

  • 5000 mAh and no fast charging?????

  • Received 300 mb plus update...

  • After i bought My Asus Transformer Prime TF201 in 2011, with after 1 year i have issues with my gorilla glass screen, i swear i will never again buy asus phone and table products. Their customer care also sucks. Be sure to think 100 times buying asus phone and table products.

  • Moto G5 Plus is far far better

  • i purchased it seven days ago.it taking more time to charge.i am not satisfied with processor.and some time touch screen not works.after switch by power key then it works.so totally i would like to say that not satisfied with this model.

  • Zenfone 3s Max comes with 3GB Ram and 32Gb Storage.

  • Motorola moto g5 plus 2gb 16gb rom or Asus zenfone 3s max?!Pls need the answer now

  • I have used this phone. Voice clarity is good. And best part is you can use it minimum 2 days in single full charge. Good phone and value for money :)

  • I am also used many Asus phone like Zenfone 5, Zenfone 2 Laser and currently using Zenfone 3 but never faced any touchscreen problem. I think there is some issue with your phone.

  • qHD quarter HD 960 x 540 HD (HD Ready) 1280 x 720 Full HD 1920 x 1080 QHD Quad HD 2560 x 1440 UHD Ultra HD 3840 x 2160

  • Dearest asking science friends.Besides gsmArena glossary,it is useful to mention that nowadays most usually we have : QHD=960 to 540, HD=1920 to 720 like this smartphone, FHD=1920 to 1020 ,and FHD=1440 to xxxx which refers to vertical and horizontal locations of screen density resolution,if I am not mistaken!!About this model:A good midrange with amazing 5000 mAh battery capacity that its record has not yet broken in smartphone categories!!Justice Rights.Omid12Omidvar.

  • Which gorilla glass used in zenfone 3s max

  • Is it support gyroscope?

  • It's mediatec.. not Intel

  • Read the specifications

  • i've been using Asus for many years. no issue at all. make sure your phone is genuine. :)

  • Asus phone is bad, ghost touch on my zenfone. to many ghost touch case on Asus phone. Don't buy Asus

  • This phone restarts when connected with some specific wifi.. For example jii wifi hotspot, iball baton routet. Phone continuingly restarting unless i switched off the router or go out of range. Coz i dont have time to toggle wifi in phone. 2nd big issue is that, suddenly a ghost touch my screen within 10 20 sec of starting any work.. Then touch disabled.. Then i have to do screen off by power key and on again.. But again i can work for 20 sec only.. I m thinking it is my biggest mistake in purchasing phone..

  • 3s max is volte or lte connection plz tell me gyz.....

  • Its much expensive than MI Note 4, price difference is almost 4000 which is really high. Also, specification of MI note 4 is far better then ASUS at really low price, sorry ASUS

  • Still using zenfone 5 without any problem last 2 yrs. Is 3S max hax intel processor?

  • i used asus zenfone 3s max for the past two weeks. i realy upset about keypad dialled very slowly

  • battery drain

  • hi I love this phone

  • Whether already in indonesian ?

  • Where can I buy it in Europe?

  • What about in call voice quality which is the main required feature of any phone. Whether it has built in call recorder ? Pls do comment.

  • Any one please suggest me Front and rear camera quality

  • The battery capacity is huge, unfortunately this phone with no fast battery charging

  • From what I know, Li-po batteries are better than Li-ion batteries

  • lol maybe you just got bad luck my zenfone 5 is still working and haven't been repaired. It's over 2 year old now.

  • this phone would be great among it's price range, if the feature of fast charging exist.

  • You need to bear in mind that this particular model ZC521TL is intended for release solely in their India and Africa markets, so the availability/cost of fast-chargers and USB-C sockets and cables is probably a lot more restricted than large western countries. So the larger battery assists with people in more rural areas who might not be able to charge up in every vehicle/office/cafe etc whenever they want, and gives them enough power to easily last a whole day or more and can be left to charge overnight Just my 2-cents :) I just wish US/EU phones from major brands like Samsung/Sony/LG etc came with that size battery on a standard 5.2" model, it's what, about half that on most of them? I'll be keeping my eye on Asus to see if they make a higher spec 'major market' model with the battery kept in tact, fingers crossed!

  • Hey why Asus is not available zenfone 3s max in black color???

  • Idk man someone at Asus wasn't thinking. It would be a great phone with USB C but nope. They ruined it

  • omygod why would you make a phone as great as this with a 5000 mah battery and no usb c?!? why micro v2??? wtf did anyone look this over and be like "oh hey this'll take 7 years to charge but it'll last a long time

  • no quick charge at all no worth the full charge take 4 hours!!! u can also use the battery to charge another phone, but when u dont have access to any qucick charge, its not matter the battery is 5000mah or even 10000mah

  • Bro pls check your handset have sim and memory card or that is dummy phone. 1 week battery the best comedy of 2017. The asus 3S FOUCS only 5000 mah battery. the very old mediateak processor MT6750 we very well know this processor in oppo f1s and vivo v5. all the chaina made are using this kind of poor performance handset.The diplay only HD. very poor camera f2.2. only thing 5000 mah battery when we get full good spec with good price. 5000mah li-polymer battery is very bad why dont li-ion battery. samsung a9 pro using li-ion battery it give super battery back up.

  • It have have a video call option in phone dialer??

  • Any chance this will have Gorilla Glass?

  • Just get an after market fast charger... problem solved. smh

  • Don't take this phone... Best option for you red mi 3s

  • its a big problem for me if this phone doesnt have quick charge. 5000mAh will takes about 4+ hours to fully charge. samsung galaxy a9 pro comes with fast charge and it takes 2hrs and 40 mins to fully charge.

  • Well, why would you need fast charging if this could last you 2 days and you charge everyday.

  • 5000 mAh and doesn't have quick charge?

  • im so excited about this phone.. 5000maH battery

  • When for the famous GSM Arena battery test? It would be very good to compare.

  • the design built of the phone is a copied one looks like samsung j series

  • though it claims to compete RN4, but its not worth of, in comparison to its specs. RN4 still the winner.

  • I have the Zenfone Max with 5000 mAh and no fast charging. It is true that charging to the 100 % takes almost 4 hours. But then you have fuel for a whole week! I usually charge mine once a week, the friday night.

  • from the front like SAMSUNG n like LG from the back view, love the old model

  • Are u sure you are from planet Earth?

  • 5000mah battery with no fast battery charging...

  • It's practically the same phone as the one listed on this site as Asus Zenfone Pegasus 3s

  • Looks similar to Samsung phones

  • heats up all the time

  • Go for redmi note 4

  • First xD Seriously, not a huge fan of mediatek. Depends on the pricepoint though.
