Today, I woke up to my Huawei Watch not responding when I pressed the button. So I plugged it in, waited about an hour, then came back. It said that the battery was almost fully charged. So I took the watch off, and it the screen went blank. No response or anything. I put it back on the charger, then immediately it started booting up again. Took it off, and it went blank again. Tried factory resetting it, and it didn't work. Any help?
