Home button doesn't work on a lock screen, but works when unlocked
I recently replaced a touchscreen, everything seems to work but couple things don't:
1. Home button doesn't work when the phone is locked. although if I call a lock screen with power button and then press home button it works. Also if I lock the phone straight away after it was unlocked the home button start working for some time until iphone is locked and nobody touched it
2. When I first powered on the phone after touch replacement I got a massage that it's impossible to active Touch ID. If I go to Touch ID settings and toggle on 'Iphone Unlock' it says "Failed Unable to complete Touch ID setup. Please go back and try again."
It was working fine before I shaped touchscreen, I didn't do any SW updates in between.
What could be a root cause of such a weird behavior?
P.S. This is my second touchscreen replacement, first one wend smoothly. Only one difference, second touch had its own dynamic rubber which was glued to the screen, so I used a new one.
Is this a good question?
