I have tried EVERYTHING to get my Samsung Watch to be completely silent while sleeping. I have set up nightly automatic DND mode, and have also tried turning on all three silents modes: DND, Theatre Mode, and Goodnight Mode. Nonetheless whenever I move my arm while sleeping the watch will wake up, vibrate and make some kind of notification noise. This is extremely irritating and I don't understand why it would do this while in DND mode (and the other two modes as well). Please help. Thanks.
