Did you try clearing your app cache and Ram?

RAM is cleared every time you turn the phone off or restart it. Clearing RAM while the phone is running just wastes battery.

Clearing the app cache (From Settings/General/Storage/Cache) and the system cache (from starting in recovery more) might help - if it's not a hardware problem.
