Why has my A9 switched to the start up screen and started vibrating?

[AC Question]

Why has my A9 switched to start up screen and started vibrating?

It had plenty of battery life and all of a sudden it switched to the start up screen and won't stop vibrating, sounds like a motor. I can't switch it on or anything.

Try to do a force restart
