Pin login fails when unplugged

[acrux]

Seems to work normally if plugged in.  When running on battery(any state of charge) the pin screen is only up very briefly unless you are constantly touching the screen.  On the rare case the phone does unlock, the screen very quickly goes black and locks again.

Seems to be an old bug when setting the screen timeout value wrote incorrect and very short time values to configuration file. So the updates do not help. You have to either manually correct the value or even better - flash the latest software image
