Only top half of the screen works for touch
I've got a situation where 100% of the LCD (iPhone 6s) works but touches are registered only on the top 50% of the screen, meaning I can turn off the phone but I can't unlock it. I was thinking of replacing the LCD but wasn't sure if this would actually fix the problem as it could also be a problem with something further down the chain. Thoughts on whether replacing the LCD assembly (including the digitizer) will solve the problem are appreciated.
Is dit een goede vraag?
