I have the issue, that sometimes the display doesn't show anything anymore. Most often this occurs with Newpipe App watching YouTube videos.
When I click the Fullscreen button while watching a video, the sound still plays. But the display is all black. I then have to press the power button to put the phone in standby, then it works normally again.
Also happens in mull with YouTube videos.
Funny thing is I got the same error on Pixel 6 Pro sometimes as well.
Does anybody else experience this and maybe has a fix for that?
