iPad 3rd gen crash and power off issue
I have ipad 3rd gen iOS 7.1. In the past few hours when using internet(safari or chrome), Netflix, and games some weird things happen.
1. Screen goes black for a few second then returns to lock screen. And/or
2. 'Slide to power off' appears at top of screen along with an X to cancel at bottom of screen and/or
3. Continually get pop up to login to itunes.
All of these things have occurred independently of one another and sometimes they all occur within a matter of seconds.
I have tried: rebooting, logging in to itunes when it think I am not logged in, uninstalling and reinstalling apps, resetting itunes password, and now reading forums.
Suggestions? Feedback? Solutions? Anything would be a great help right now. Thanks!
