I will be in an app and then i get kicked out
I will be in an app like facebook , email, or safari and all of a sudden I'm kicked out like if I pressed the home button but I did not .
Is this common or should I be worried . Also my volume will not work at time on certain apps and if I hit the home button to get out and go back in , it will work . ??
iPad, iOS 6.1.3
