Digitizer is on when screen is off

[klick]

There may be an artefact with the screen waking up unexpectedly, I need to check but with the phone running on battery, screen off, after 10 or 15 minutes it is all lighting up sometimes. This may have been some kind of notification about low battery power as my battery was sinking below 20%.

This is probably be due to a notification yes, based on my testing this is the only case where the display wakes up "by itself".

I am also having an issue with the phone waking up and the screen staying on for extended periods without any external input. There does not appear to be any notifications that I can find. It wakes up for about one minute then shuts off.
