Hi all - I have been experiencing GPS accuracy issues with my fenix 7s Pro Sapphire Solar since around Sept/Oct this year, and it seems like it is getting progressively worse. Often my runs/walks are tracking almost 25% longer than they actually are because of the jumpiness of the GPS data. I do a lot of exercises with my partner who has a fenix 7 Pro Solar, and his GPS data has no issues. I also previously had a fenix 5s Sapphire and there were no GPS issues in the same areas.
I have restarted my watch and reset to factory settings. I have satellite set to All + Multiband (my partner has his set to the default setting). I tried changing Data Recording to Every Second for a while, but that made it even worse. At the moment I'm trying out having 3D distance and 3D speed for my trail runs turned on, but it doesn't seem to be improving anything.
Example of my GPS data:
Example of my partner's GPS data for same route:
I've emailed Garmin Support a couple of times but haven't heard anything back.
Any suggestions/help would be hugely appreciated.
