Do you have any taskillers? antivirus? ram apps? booster apps?

restart your phone and check again.

Yes,i have clean master,avast,nq mobile sequrity
I restart my phone and turned off and on ten times,remove some unimportant apps,but nothing changed.
Untill i upgraded my phone to android 5.02 this problem appeared.
In safe mode too.
