I can't seem to get into this state with just the given STR.
I think there's some additional steps that are needed to get to that state...
I'm not sure what they might be. 

Do you recall some of the things that you might have done before this occurred?
Does it happen once you reboot?

1. Tarako attached via USB cable to computer and charging with a very low Battery (less than 20%) for at least 20 consecutive minutes in a flat position. (prior to that, device was in constant use for nearly five consecutive hours). Device was being charged at the same time a Buri was being charged on the same computer using a different USB slot. Each device had the charging icon displaying in the status bar.

2. Disconnected both Buri and Tarako from USB and walked 10 feet to another location in same room.

3. Set Tarako on a special apparatus that holds device to take video without user holding device.

4. Placed Buri in separate part of apparatus to capture video from Tarako.

5. Tap Camera App

Bug encountered.

Note - the apparatus described in steps 3 and 4 above has metal ends attached to plastic straws atop a recyclable box but has been used in the past capturing video using a Buri without a problem. This was the first time placing this particular Tarako on this part of the apparatus.

Testing this morning (Friday, April 25 -using the same April 24 Tarako build) placing Tarako atop this apparatus with a low battery and recent charging simultaneously with a Buri and following above STR did not reproduce the issue reported in Comment 0. 

Note - Passcode lock was enabled Thursday April 24 and Friday April 25.

The phone was not rebooted on Thursday April 24 prior to encountering the reported issue.
