Similar issue I went for a swim 2days back turn my water lock mood on when I was finish I turn the eject water on and it started rebooting until the screen is just blank plus it wouldn't charge keeps blinking red
my samsung watch wont stay on for more than a few seconds. After it shuts down, it cant be restarted unless I place it on the charger for a few seconds. Watch stays on if I keep it on the charger but, as soon as I take it off the cradle, it powers off. Battery is showing 100% when on the charger.
I bought two last year. I'd the same problem. The first time it happened, the watch could be reset using the app because although the screen will not turn on the bluetooth connection still works. After that the watch worked propertly for about two month and now it happened again. But, this time, when I tried to restart to factory settings using the app the watch disconnected to the app and could not reconect anymore. Now, when I press and hold the power button for more than five seconds the watch, after other 10 seconds, vibrates two times and that's all. Very dissapointed, as I could see many people have the same problem, so you should assist them because something in your product is wrong. If I did something wrong in my job I should solve it because it is the only way to do the things well.
Ok, so I was wearing my rm-800. All was working fine, fully charged overnight, when it just suddenly went off. When I try to switch it back on it shows first galaxy screen then switches off, I can get to reboot screen but cant select anything as top button seems to have given up aswell!! Any ideas, its just coming up to a year old, no damage and everything is clean.
If the troubleshooting in the thread was performed to no avail I would recommend getting your device in the hands of a technician to be evaluated and repaired. I would be happy to look into service options for you, could you please provide me with the model and serial number in a private message? https://bit.ly/2SUXRar
