once you update to a newer version of android. the added features would also eat up ram. so this is as expected. I suggest to uninstall uniportant apps or review background apps settings>apps

No way. I tried all ways to solve this problem. Companion,reset,downgrade to lollipop,rebear,. I try all ways you can imagine. The problem is it bad phone.all Xperia phone full of problems. This phone no body should have. It is useless.

Coustmour service too bad all they can do. (reset,........

You should all know that it is Sony responsibility.

No way

haha short storyline.. your ''another'' 1 GB of ram it's dead.. i have the same on my M4, except that mine ram got dead even when i had Lollipop 5.0.. started with restarting it self like crazy, then didn't want to boot even, i was able to receiveing SMS but cannot make phone calls, both sim cards shows no network coverage, if there was network coverage i was not reachable too just as i mentioned i was able to send and receive SMS.. the mobile data was working fine, and the wi-fi, i still keep the phone, but after the ''dead'' 1 GB of ram is slow and sluggish.. almost not usable.. and yes the restarts still happens not that often now after the ram got away.. but still happens.. oh and just to add.. this about the 883 mb ram.. was discussed long time ago.. but Sony denied to replace the motherboards.. not nice at all from their side

aha i see.. okay if it's not.. then where's the other 1 GB of ram.. ? i was following the forums back then pretty often, then i didn't had that problem, but now i do, so how can i return my previous ram ? as i know it by replacing the motherboard, on my own.. i'd have to pay for it, since my warranty is gone.. and even after the replacement, how can i be sure, if the motherboard would be lasting longer, or would just colapse after 3 months of using ?

@Aleks011

When you replaced the motherboard, which Android flavor did you flashed?

after 1 month my 1 Giga came back . the problem is the sd card .if you use under class 10. you must replace it with class 10 . sd card make some wrong with ram storage . (both connect with motherboard)
now all i do is to pull the sd card out ,turn of the phone,put sd card again,turn on again .
maybe 1,2,3 time
now ram is 1.8
2 days the phone restart after 20 m but now all the day only 1 restart

no you didn't get me, i still have the old faulty motherboard isn't changed what i did was updating from Lollipop up to 6.0.1 Marshmallow, but didn't change nothing except the phone isn't restarting that much now (and as i said earlier i lost the other 1 GB of ram on Lollipop version 5.0 not after upgrading to MM), but still 883 Ram.. And no, i don't have SD card inside i have 16 GB version E2363 dual-sim, back then i had like over 50 system accidents when on Lollipop, now is less

No need to change motherboard.. not lollipop, mm cause that problem. The problem inside slot of SD card. here kind of oppose haben between SD card and ram storage in motherboard. At Once this giga gone. If you try to put and out put SD card while device is on then turn off. Wait 5 second and turn on again. Repeat 2 or 3 time your giga will come back... That's exactly what happen with me

seems like you don't understand very well English.. i said i lost the 1 GB of ram on Lollipop not on MM.. after i lost it i did the update in hope it would fix the problem. Everything started with restarts, then was impossible to make calls, was loosing the network, wasn't detecting the sim cards and so on.. and i'll repeat myself again... i don't have SD card.. so SD card can't be the problem.. and if you thought that would fix my 'missing' 1 GB of ram by installing.. then power off etc. i haven't tried, and also i'm not optimistic that it would get fix

Make sony recognizes this issue

It seems too much of us are facing this lost of RAM issue since the last update! (writing from France sorry for my english)

I only own my xperia M4 aqua for the last two years and already payed for xperia care to change my screen last year.

Is there any users or customers group somewhere or to create in order to make sony recognizes this issue?

- please Sony try to quickly fix it

- Please Sony if you can't fix it, refund or send us a new xperia m4 aqua, give us a least a 50% off on a new device.

A very disappointed user that surely never buy an xperia anymore nor telling good to around me, social networks or forums if Sony doesn't do anything.
