Not that weird. It does happen and is a common symptomatic precursor to hardware failure.

If it happens and you can't turn the device on (Pixel 5th Gen and < ) and you plug your phone into a PC and see Qualcomm HS-USB QD-Loader 9008 or similar then the device is dead.

If you use a 6th Gen > Tensor device this won't happen.

If you see these with more regularity and can grab a bug report (SETTINGS>SYSTEM>DEVELOPER OPTIONS>BUG REPORT>INTERACTIVE) and then make yourself known in our Matrix support room, we can look into it further.
