My screen display showed first black, then a steadily increasing number of horizontal white lines across the face of the watch until white filled the whole screen. The white screen remained for about 3-5 seconds, then went black and the watch was shut down. When I rebooted the watch it came back up normally and showed the time etc as usual ( I use Power Save mode most of the time). Since then, all seems normal except, even in Power Save mode, the battery lasts 12-14 hours and have to recharge every night.
Anyone else seen this issue and dealt with it? I haven't done a Reset yet, waiting to learn if there are any other solutions. Thanks.
