If you want to submit something that only the postmarketOS Core Team can see, write to team@postmarketos.org instead of opening an issue here! --> ### Describe your issue When dimming the screen (manually or with automatic screen brightness), the screen is able to go completely black. It is very annoying, as it typically requires a reboot to fix (more on this below). Also, it has made me stop using auto brightness, otherwise the screen will just be black if I wake up the phone in the dark. #### What's the expected behaviour? When dimming the screen (manually or with automatic screen brightness), the minimum value should be very dim, but not completely black. #### What's the current behaviour? When dimming the screen (manually or with automatic screen brightness), the minimum value is _completely_ black. This makes it so you can't see anything on the screen, even in a pitch-black room. In most cases it forces me to reboot, unless I drag the brightness slider all the way to the left, watch it go black, and then move it back to the right, all **without removing my finger**. It seems like the screen may not even accept new touch inputs, after it goes completely black; If I remove my finger after it goes black, put my finger back down where it was on the screen, and then drag the slider back to the right, nothing happens. #### How to reproduce your issue? Drag the brightness slider all the way to the left (dimmest). The screen should turn completely black. ### What device are you using? <!-- Leave name of your device in vendor-codename format.
