Screen has begun to melt away from the back due to overheating
Also down both sides were it is coming apart, there is slight discolouration. The back camera has stopped working completely. The battery drains very quickly also, has anyone else had any of these problems?
the phone can't overheat as it will shutdown, if you have unlocked the bootloader and flash a custom ROM or rooted the phone and overclocked the CPU, etc that could happen.
