Hello,

Hello,

I've got a problem with the display of my Fenix 5S. All my family have a Garmin watch and i've unplugged the forerunner 245 of my son then plugged my Fenix and it froze. I do a reset of my watch to enable it again but since that, it remain blue line on the display. this line appear and desepeare regulary. It happen on every screen: watch, run, bike....
here are a picture of it. any idea ?
Regards.
