Yes I did the Facebook and Messenger thing but the problem is still there. But I will not use task killers as they are useless and they use more battery than save.
I even performed a wipe this morning and the problem does not disappeared.
Thanks for your help.
I see that you are having the Android System problem as well. Weird thing is that it does not seem to keep awake the phone.
Would you mind posting the apps which you have installed now?
