I am unable to get into my tablet after leaving it on charge. The unlock requires a PIN and biometrics are unavailable until next time. I enter my PIN and it just takes me back to the lock screen. It looks like the PIN unlock is crashing.
Because the PIN unlock doesn't work I can't reboot or shut down either.
How can I get around this? The battery is at 100% so it'll be over week before it runs out.
