Device turning off after screen replacement
OK, so I dropped an iphone 6 and the screen was a mess (both the glass and the LCD). The screen protudes a little on one side due to a slight bend in the frame. After a new screen, which works perfectly, I'm now finding that the device turns itself off after 5mins except when it is connected to a power source.
Has the repair guy done something wrong? Or is the phone just broken? Will apple repair it out of warranty or is there something I can do?
