Right now I have Do Not Disturb disabled and I still can't get the backlight feature to work through Gesture in the middle of the night. When I move the watch face towards my face when I'm in bed nothing happens. I used FitBit previously and for its lack of features this sure did work very well with the device. Can't say the same about Garmin that costs way more than Fitbit. You would think since their watches are more mature in terms of tech they would have something so basic figured out. But by the number of posts on this topic on this forum, it seems like an outstanding issue.
