Sometimes when I go to unlock and 'wake' my device upon the first press of the power button nothing happens, upon the second press a few seconds later the screen turns on and then instantly off. It then requires a third press of the power button to wake the phone.

This usually happens after medium/long periods of the device being locked, and I've only experienced the issue when the device is not powered by USB.

Also note that while experimenting I pressed the button once, the screen didn't turn on, but then when I plugged the device into USB power the screen turn on (this could have just been a coincidence with timing).

I wasn't sure which project to report this bug, so please assign elsewhere if this is the incorrect place, also I couldn't see anything obvious in any logs so any suggestions for debugging would be much appreciated.
