The app use 600+ MB of RAM as it runs in the background. Out of 4 GB only
1.5 GB is available as lot of app (not visible) use up the RAM. Even after
cleaning up the apps using clean master it display 1GB RAM free from apps
but after few seconds it is back to 2.8 GB RAM utilised by various tasks?
I wonder how the other ZenFone model with 2 GB RAM is doing?
