[Google Pixel 4a 5G Themes, Apps, and Mods] Schischu:
There seems to be a bug in combination with Android Auto.

Screen stays black and phone needs to be rebooted.

Not sure yet which option specifically is causing the issue in ROMControl.

Can be easily tested. Just start Android Auto app on your phone and after 3sec screen goes dark.
