@Logan1 just out of curiosity, have you tried the Lokmat APPLLP 4 latest firmware version on the watch?
It is compatible and I have flashed both without problem - on the same watch.
Don’t flash the unbranded version though because I believe that it has a different screen and touch panel will maybe not work.
I’m just curious if this video call bug is on the newer Lokmat branded firmware as well, or is it just the LEM16.
If you are not comfortable using the flash tool - please don’t worry about it.
Cheers.
