why does my iphone 5s 64 gig overheat and shut off
I have an iphone 5s, When i updated the IOS it killed my wifi, so no wifi on this phone. I use 4g. Now its been about 7 months and it randomly overheats (really really hot. I have to put it down) and shuts off.
WHY? What to do?
iPhone 5s, iOS 8.3, 64 gig
