I answered a call, hung up, and set it down. Came back about 5 mins later and touched the home button..... nothing. Held the power button........ nothing. Tried to make it start up in DFU........ nothing. Absolutely zero response whatsoever. Solid black screen as if it were off and completely dead. Plugged it into the wall and the home screen popped back up like nothing was wrong. Unplugged it and seems to be as normal. Still has 100% battery power as it has been charged very recently. This ever happen to anyone?
