I saw another post about this problem but it was closed.
I just got my pixel brand new from Best Buy at Christmas. I installed GrapheneOS right off the bat and have only installed fdroid and Aurora store apps.
It has occurred a few times where I had been using the phone and when I tried to wake it up by pressing the power button, I got no response. I thought maybe the battery had somehow drained so I plugged it in but still had no luck. I then plugged it into my laptop and it was recognized showing the pictures folder. Clearly, the device was still on but the screen was off and unresponsive.
The other post suggested that this was a potential hardware issue and left it at that.
Hoping there is something we could do or check to figure this out with the fact that it's accessible through USB connection.
Thanks in advance for any suggestions.
The only way to recover has been to hard reset with the power and volume up buttons.
