I updated to iOS 7.1. Ever since I did, everytime I prolong staying in facetime audio for at least 40 mins, my iphone restarts on its own. One time though, it completely shut off despite how many times I tried turning it on, but it did work when I pressed & held both lock button and the home button. So my question is, why is this happening? This never happened on the previous iOS.
After 20/30 minutes of audio facetime, the iphone suddeny reboot. This doesn't happen during the video facetime. I believe this is a serious bug in iOS 7.1 because I never have this kind of proble before. Hope Apple fix this problem soon.
