Had the problem that my Android phone always turned off the screen and required the fingerprint to turn it on. When the screen turns off f. the flight path display was deactivated, the cell phone battery was empty after a 40-minute flight.
I found a possible solution with => Settings => Lock Screen => Smart Lock => then under "Trusted Devices" e.g. B. Register Galaxy Watch (the DC-24 II is not accepted). Then just press the power button briefly to activate the screen again.
Don't know if there's a better way.
Navi and video programs are able to prevent the screen from switching off, Jeti Studio M could possibly have this installed too. In my opinion, it is best to have the screen turned off after an adjustable time to save power - see above - and e.g. B. switch it back on again with a quick swipe across the screen or voice command.
