My watch does not seem to respond to any Gestures. I have set the backlight to turn on for gesture for both any activity and non activity and have also set the notifications privacy to respond to gesture yet none of this seems to work. When I lift my arm and turn my wrist, nothing happens. Does anyone else have this issue? I am running the firmware: 3.10
One thing to check would be what you have to setup for your sleep time and if 'do not disturb' is set to on. Press and hold up/menu button: Settings->System->Do Not Disturb. Check sleep time and Do Not Disturb setting.
You might also want to make sure the watch is set to the same wrist you wear it on. I have my watch set to only light up on gestures after sunset, and my gestures work between sunset and my bedtime. The back light does not come on when I sleeping.
