Well lets try this again since my last post was deleted.
BV9800 will periodically throughout the day stop taking touchscreen input, I can't access system buttons on screen or manipulate the device.
When I press the physical buttons they respond volume/ptt/power. When I press the power button the screen will turn off and upon next unlock the screen will start working again normally.
This can happen at any time of day without warning even when in the middle of typing a message. Though subjectively it seems to happen more when on "Night Light" mode, and turning it off can help it happen less frequently.
Any suggestions before buying a new screen/digitizer and swapping it out?
