Why does shaking my iPhone make touchscreen responsive?
I have a purchased a used iPhone SE that I just recently noticed goes through periods where the touchscreen doesn’t respond at all. These are intermittent and there doesn’t appear to be any fixed period of re-occurrence. There are no visible signs of damage to the screen either in cracks or dead pixels. At first I attempted force restarts to clear the problem and generally anywhere from 3-7 force restarts will cause the screen to respond again. I’ve also reset the phone and restored from an iCloud back up, but still experienced the same issue. Recently I’ve notice shaking the phone, a bit more vigorously than you would to use the shake to undo feature, will also clear it. Is this a software issue or am I looking at a screen replacement?
Es esta una buena pregunta?
