Free ram is wasted ram.it reserves the ram to be used when needed the less free ram the better!I don't know why but it only happens with the dialer App and not always,sometimes.
It never happened with 3.4 but a few times with 3.6 and above.
Before you take the call there's a black screen and when you finish talking it gets black again for a few seconds.
I wanted to ask KitKat users,is the ram management better?
With stock Jellybean and Dori's kernel I get 600MB free ram in the best scenario while I have a ton of Apps greenified and no location services on.
I see that Apps like radio,messaging,quick remote and a few more run all the time in the background while I try to kill them regularly with Task manager but after a few minutes the same story.
What reserves all that RAM?
I tried converting all the above Apps to user Apps from system Apps with Titanium Backup but unfortunately for the specific ones I don't get that option
