Anders_ASUSThank you. It is a good idea. But I don't why only the lower airTrigger can be set. No any response to pust the upper one. With AirTrigger I can only use Rog 2's camera instead of seclecting some other app like GCam.
All gestures have the same level of security so it's not really suitable for the camera when your phone is locked.
I recommend you to use your AirTriggers for this function instead. Go to the quick menu -> long press the AirTrigger button -> enable it -> set either the short or long squeeze to activate your camera
