Possible to manually set display brightness to 0 on Ubuntu Touch

It is possible to move the brightness slider to the very left position,
which will set the display brightness of affected device to zero, or, to
total darkness.

This is a bug, since this leads to user's inability to set the brightness back or, generally, to operate the device.
There is a slight chance, though, to return the brightness back to non-zero value (blindly, trying by user's memory).

Also, this gets even more problematic, if we think about a scenario, where such Ubuntu device is locked by a PIN.
User has to try to unlock the device on the dark screen, open the top panel with settings, scroll to the far right (to access the brightness settings), and then trying to hit the correct slider - all on a dark screen.

This happened on Aquaris E5.
