I finally managed to solve the problem on my honor 9 and the orux does not stop recording.
The problem was I could not find the orux's widget.
I uninstalled the old version and installed the new version again. The orux's widget has appeared. I put it on the screen and "Ignore battery optomisation" and choosing "FUSED LOCATION PROVIDER" in Orux and everything is ok!
Regards, Kriton!
