Whilst in my pocket, I have pulled out my Nexus 6P and found it has rebooted (at least this is what I assume as it now wants my full passcode and will not allow unlock with fingerprint).
I also find that the time is wrong. It has reset back to 1st Jan 1970 12am. I have not been able to get it to correct itself (via my network - EE in UK if that matters).
The only fix has been to disable automatic time sync, manually set it, and then re-enable auto time sync.
How can I get this to auto rectify the issue next time it happens? Its very annoying!
I am fully up-to-date with all software and patches.
