I updated my Galaxy watch to the latest One UI 5.0 and decided to turn on universal gestures, since I found it interesting. It worked find throughout my day, only problem was that I kept forgetting which gesture was for what. But after a while I got used to it and was able to remember what was what. But once I went to sleep I noticed that everytime I moved my arm, the screen would turn on saying "wake screen with shake gesture." And I found this annoying, Sleep mode should disable universal gestures when people sleep or their should atleast be an option to make it do that.
