My mobile information.
i have Samsung Galaxy Y Duos GT-S6102
I am using the Stock ROM, My mobile is rooted.
I am also using GO Launcher EX and Go Locker.
When i am using my phone for a while it is fast, for example switching the AppDrawer screens, Open Messenger close it again, Go to home screen instantly after pressing ( Home ).
but when i leave my mobile for a while ( 10min + ) it become slow ( when i unlock the screen the Home screen appear after a while, the app drawer take long time to load and is laggy while switching screens, opening an application take a while too.
1- I Don't have any Auto-Task killer applications ( i had before but uninstalled it )
2- I noticed that my phone lose Internet Wifi connection too, because when i open FB messenger it show me the "Connecting" message.. i also doesn't receive notifications after leaving my phone idle for a while.
3- When i unlock the phone and start using it the notifications are revived ( delayed notification )
