How do I shut off the green light on the back of the watch.
Question marked as
The green light is the heart rate sensor of you Apple Watch. If you're not currently having a workout running on your watch I would suggest restarting your watch to reset the sensor. Normally it is only continually on when doing a workout, or in the 3 minutes after a workout.
