About a month ago, my screen would stop working. It was still connected and button presses would still cause haptic feedback, so the watch was responsive. Rebooting would fix it for a day. After a week of this, I performed a factory reset. That fixed the problem for about a month. Earlier this week, it started doing it again, though the two times it occurred, were two days apart, where before it happened every day near the same time. Put in a call to Samsung and since I had already tried resetting it, they are having me send it in for repairs. So basically no known quick fix that Samsung could recommend. Just posting this as an FYI in case anyone else runs into the same problem. I also am not sure when I upgraded to Tizen 3 so I'm not sure if it's related to that. It worked flawlessly before the issue started to occur.
