Curious crashing behaviour in iPhone 5
iPhone 5.
Background:
Had been sent to 3rd party repair shop for power button repair. Harmful modifications may have been made.
Battery had been replaced before.
Phone had been self-opened to fix a certain problem. Help courtesy of iFixit.
Above operations were carried out at least a month before crashes started occurring. Most probably not the direct cause.
Symptoms:
Crashes cause screen to half its brightness or develop bands of colours. Phone would be unresponsive, requiring a restart. Phone may restart itself automatically sometimes.
Cause:
Crashes occur if i pinch the top of my phone, ie press the glass into the alum case. If care is taken to avoid the cause phone will not restart randomly.
I suspect a short circuit somewhere at the top of the phone, but cannot verify.
1) Would anyone know the possible locations of a short circuit?
2) Can anyone propose an alternative cause?
Thanks a lot.
Is this a good question?
