Screen no longer turns on after setting "watch mode"

Set mine to watch mode for convenience, however the screen no longer comes on when I tap the power button. Instead a brief flash of the power down prompt comes up and the glance screen turns black. full power down does not resolve

I hard reset the phone. I was able to access the interface only after turning it back on with the charging cable connected. But if I turned the screen off or it timed out, same problem.

I hard reset the phone then turned off watch mode so there was no more glance. Screen would not turn back on at all.

I hard reset then factory reset :'(.... Finally back to normal.
