have been using it like 1year+++ and it finally k.o last week. The front camera was such a pain bcuz it doesnt have setting for the mirror effect/not so your picture will turned out weird. The rear camera, i have never been able to use it since long time ago cuz it always crashed (cant even open the rear camera tho). As im someone who is learning korean language, havin no choice to write in korean with xperia keyboard is also such a pain cuz eventho i installed app with korean language, i cant use it bcuz the phone have no does not support the language in other app. And lately (before it truly dead) it have the overheating problem where i have to keep it in the fridge or wrapped it with dump towel to cool it down. The storage too, as everyone knows (i used the 8gb) 4gb is for the system applications with lots of app that you dont even knows when to use it or is it something you need for your phone, i have to always clear the caches to make space for it to keep operating. It doesnt have lagging problem and thank god for that one good thing.
parthi, 12 Jun 2017I have problem in using 3G network what problem, describe it, maybe i might help you somehow
RAZIN.Rmcf, 08 Jun 2017have u update to 6.0 on ur phnnope, i was about to update.. but glad i found out on time, that the MM 6.0 is causing that big hardware problem, so i decided to stay on 5.0 and i'm happy about my decision
I'm really disappointed that there is an SD card option but I cannot transfer data from the internal storage to it. The internal storage is full and I had to delete many important apps to keep the phone going. What is the use of having an SD card if I cannot use it??!!
Nani, 02 Jun 2017Worst phone ever don't buy this one. In one word you can make an omlet on phonei agree with u brother & internal storage not enough otg function not support....
Anonymous, 21 May 2017Hi everyone! M4 aqua is one of the best low budget smartphones in the market right now..but i... morethat bug appears only if one going to Marshmallow 6.0 android update.. otherwise if one choose to stay on 5.0 Lollipop, everything going to be fine (as i said in the comments little bit down, i'm using this phone pretty heavy since November 2015) and is just awesome, tho i don't get why Sony did not replaced the faulty components or the motherboard for free.. that's bad from their side.. but that's it, glad i learned before i decided to move to MM.. so after all the posts i read, i decided to stay on Lollipop and be happy with my phone more time :)
worst phone that I have ever bought
mic issue at the 8th month of purchase
blue screen issue after one year
they are asking to replace the motherboard
Worst phone ever don't buy this one. In one word you can make an omlet on phone
In my opinion M4's everything is so guud..
But hardware is too weak
In 8 months, every month I need to repair the phone in service center.
M4 aqua is one of the best low budget smartphones in the market right now..but i don't recommend anyone to buy it because it has this 883 Mb ram issue which makes the device crash constantly with a blue screen. And you have to replace all hardware components in the motherboard to solve this issue which is very costly. Sony "support" is not very supportive after all. From a very sad former sony m4 user!!
Rahul , 22 Apr 2017Don't purchase this mobile please So very bad really Only 5 min use and so very hit th... morefirst learn English better then comment. Don't fool other peoples with your opinion, maybe you got faulty phone, but that doesn't mean every M4 Aqua, would suffer from the same problems, example.. i have mine M4 since November 2015 and till now May 2017 had none problem and i'm heavy using it, Facebook, Messenger, Games etc. The phone it's just brilliant

Don't purchase this mobile please
So very bad really
Only 5 min use and so very hit this device
Please please don't purchase please
I dont know why people are having problems in thia phone. My M4 aqua dual works smooth n fine. And also please dont upgrade it to Marshmallow because that operating system is too heavy to handle for the motherboard which is employed in this phone.
The major drawback is DUAL LTE. You can only use LTE SIM in SLOT1 and can only use the data traffic but not calling. If you want to do both then put your sim in SLOT2 then only you can call and use 4g Internet. GSM sim can't be used in slot1. So i think this is one of the biggest drawback of this phone. Else performance wise its superb.
