I bought a used HTC 10 that said it had a dead touch screen zone at the bottom of the display. Using a drawing app you can see there is a half inch tall dead touch area that spans the entire display. Visually the LCD works. The odd thing is sometimes it is dead and sometimes it works. On the stock Android 7 and 8 the bottom half inch of the screen doesn't work on the home screen or in apps but it 100% works for the keyboard. I installed Nova Launcher and the touch area started working on the home screen but still didn't work in apps. I thought maybe it was an issue with the stock Android so I flashed Android 10. The dead zone is gone on the pixel launcher home screen and the keyboard still works but the dead zone is still there in apps. I thought installing Android 10 would eliminate any software issues but it doesn't seem like it would be a hardware issue since the touch screen works 100% on the keyboard and homescreen. Any ideas what the issue might be? Thanks.
