Unresponsive touch screen if idle for long time
Hi all,
This is not the typcial 'gray flickering bar' desease that has been common for the iPhone 6 plus, but another problem that leaves me scratching head in despair.
The phone, when left idle and the LCD turned off for a while, gets unresponsive when interacted with. Not until the screen has been active for a while, the phone starts receiving input.
I tried to change the LCD but apparently the problem has not gone away. So I'm fearing that it is something on the logic board, and not the LCD itself?
I feels a bit like the unresonsiveness is because the internals are not heated to 'operational temperatures' or something similar?
Any ideas?
Is this a good question?
