This morning my ipad 4 feel over on the table it didn't break or wasn't hard hit but it may have hit the screen a little and after that it didn't work anymore The screen when touched seemed weird when pressed anywhere on it ! I had a hard time getting it to try and restore but every time it went to restore the ipad froze up and error codes came up 4014, 4013 So I checked and it said or I read it was a hardware failure ! Can anyone confirm that this is the digitizer .......... if so I need to buy a new one and replace also anyone replace one with a off market one ? was it any good or would you go with an apple OEM part ? any suggestions ?
