I've had my watch about three months. Sleep tracking is always worked for me until the past week. It tracks my normal sleep time from start to finish however some nights there's an hour missing. Is like the watch things I'm awake for about an hour every night. Is not the same time every night. unless I'm just up and sleepwalking I cannot explain it and none of my security cameras have caught me wandering around the house.
Samsung's first and only step is to reset any device that is having a problem.
as far as theater mode and gestures and wake up and touch and everything else, I have never disabled any of that. So I'm not sure that sleep or night mode has anything to do with the issue.
but apparently this problem has been going on for other users for a long time. Doesn't look like Samsung is too interested in fixing it. I have not had an update that really fixed anything since I got the watch.
Looks like a lot of the previous posters have just kind of given up. At this point in the game it's pretty much just an extension of my phone's notifications. Until the blood pressure feature can import data from my BP Labs 2.0 into the Samsung Health app that's just a hokie gimmicky feature. that feature does work however is just another step or two once you get through the hot mess that is the BP Labs app.
But I digress.
