Tried to sync Vivofit 3. Screen on watch became frozen with time and solid red line on the screen. Device key not working. Battery was replaced last week and was working without problem. Tried uninstalling and reinstalling app. Did not help.

Problem solved. Turns out new battery that eased recently installed was no good. Just needed another new one.
What size battery do I need...
