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.
akki, 09 Mar 2017I m using m4. It's not support otgEven I also thought but nit working its very bad
I purchased this phone Xperia M4 Aqual Dual in 2015 June, and had a worst experience with it. It started giving problems within 4 months of purchasing. The vibration and proximity were not working from the day one. The Sony service center accepted this & have to change the mother board, so you can imagine to what extent the issue was inside the motherboard.Luckily it was on the warrantee period so I was not charged but I am very much disappointed as its costed about 24K and so never expected this. Moreover after using it now for 1.5 months I again saw lots of issues like heating (specially when connected to Navigation apps like google map),low speaker sound,showing message battery not charging when connected to Sony Car Charger fitted in my Car,battery drains fast,call does not connect in first time etc etc. This time when I visited the Sony service center they say its likely that water has gone inside the phone that's why I am facing these problems.Its very surprising for me to hear that, because then what is the use of being a water proof mobile,assuming if the phone is exposed to any water by any chance,which is actually not true at all. And this time as its out of warrenty so the sony peoples are charging 14,500 Rs for repairing it. Crazy !! I am now thinking of hammering this phone as its troubled me a lot. All false tag lines like "water proof". I do not recommend anyone to buy this mobile as its a total waste of money.
My Sony Xperia m4 aqua shows 883 mb Ram after upgrading to Marshmallow. Now it goes too slow. I contacted Xperia service centre, Xperia customer care number and also Xperia Support forum. But they didn't give a solution. but Now....Wow.. They Give Solution,,CHANGE THE MOTHERBOARD. NOW I HAVE TO PAY APPROX 7500 Indian Rupees.What a solution.!!!
Before buying Xperia m4, ONCE VISIT XPERIA FORUM AND SEARCH ABOUT RAM ISSUE IN XPERIA M4 AQUA. M
MANY PEOPLE FACE SAME RAM ISSUE.
Is there any noticeable benefits after updating to Android 6.0 Marshmallow ? Is it worth updating? Also please tell me about the drawbacks with this update.
overall Xperia M4 Aqua 16 gb is a great phone but it really sucks that Sony won't even issue security updates for this 2015 model still stuck with july 2016 security updates with marshmallow I guess Sony doesn't get it that it is this neglect causes many to avoid sony phones
Worst mobile that I ever bought. After just one year of use phone has died with blue screen of death suddenly. Waste of money.
