Background: the LG G5 allows switching on the flashlight/torch by long pressing the Power button. (It is not default settings, it has to be changed in the system.)
Setup: Allow to switch on the flashlight by Power button (Settings > Buttons > Power > Long press for torch) and switch on the flashlight by holding the Power button.
Actual results: The Quick settings (pull down from the top of the screen) does not reflect that flashlight state. When the flashlight has been switched on by a hardware button on LG G5, the icon for the flashlight says
off. The icon has to be pressed twice, alternating the
off, to switch off the flashlight.
Expected behavior: The Quick settings reflects the state of the flashlight, when switched on by a hardware button. It would say
on, when the torch is switched on by Power. And it would allow to switch off the torch by a single touch on the icon.
