I need help with my fenix 3 HR.
After five years of trouble-free use, it has recently happened to me that during the activity (running, cross-country skiing) I lose distance information on the display. I have set up automatic time measurement after one kilometer and the watch will start to pointlessly report the mileage after a few meters. When I finish an activity and upload it to Garmin Connect, it doesn't show me the total distance, but it shows me exactly where I was on the map. So I am able to get the total distance from the STRAVA. I have the latest firmware 5.60, I reset the watch to factory settings, EPO is up to date. None of this helped.
The second problem I have is that during the activity (running, hiking) my altitude starts to rise to 10,000 meters, despite the fact that he has just calibrated it according to GPS. It is set to the correct data, but suddenly it quickly rises back to 10,000 meters. A reset to factory settings partially helped with this problem. The height rises during the activity and falls back to the correct values.
