M4 aqua ram

My cell has 2 Gb of ram and suddenly it decayed and lost 1.2 Gb of ram. Why is this happening?

2gb of ram are the total, about 400/600 mb are shared between the gpu and the system, if you see that the memory usage spiked it may be related to the apps you are using on your phone.

Go to Settings, Memory. Click to memory used by apps to see what app is using the most.

Just a note, if you could access the developer options and selecting Running Services you will see better information about the memory usage.

Not the total is 883 MB of RAM that's what I mean.

Well, that means you have a total of about 883mb available. If you go in settings, about phone, diagnostic and tap Facts, scroll down what do you see about the ram?

 a common fault with them, there are numerous examples of m4 aqua phones with 883mb of ram, mine included.  One of the ram chips is clearly failing.  Faulty hardware.  It isn't software or firmware.  (Yes I have done the factory reset, the sony repair function and everything else in between)

if you update android Marshmallow the ram will left from 2gb ram is 883mb ram coz the android Marshmallow system is taking also for background function..

Even in Android Lollipop this device ram is 1.1gb free ram from 2gb ram..
