    Using 3.53 beta, not sure if the "issues" are related to firmware , the chip or anythng else but you can see the GP+GALILEO accuraccy is doing really weird things, some image attached (have lot more same cases).

    Green track is from where i went running/walking, red one is the Fenix traced one...((when trying to upload photos i get "invalid file" error :confused:)

  • WOW that’s bad! Did you wait enough for a good GPS fix? It’s been a while, since I’ve seen a track like that.

    Yep, i wait like 20-30 secs after green signal.
  • The GPS version that was released to add galileo support broke the GPS tracking on the Forerunner 935 and apparently isn't working great on the Fenix 5 plus either. There is a Beta release out that is supposed to fix this on the 935, so hopefully there will be a new beta that will have some improvements for the 5 plus line as well released soon.
