perpetual vibration
My device just started vibrating and wouldn't stop anymore.
At first I'm pretty sure the screen was still open, but then I probably pressed the power button and in the end the screen was black and no other reaction.
I let it vibrate for maybe 30 seconds or so, then I forced a reboot by holding the power button.
It has rebooted and for now it looks normal.
