My Forerunner died during its first day out of the box. The screen went black during the day and after reading some other forums this happened when i first took it outside and seems to be a common issue.
I managed to get it to connect back to the app on my phone and do a factory reset only for the same thing to happen an hour later. It’s gone now, will not connect and screen is black but still has backlight.
Anyone managed to fix this before i try and get a refund?
