GPS accuracy

[Campykid1]

I use my phone to track my rides on Strava and recently the accuracy has been off significantly so segments are not recognized. I have GPS and cellular activated for accuracy.

No responses? The GPS accuracy has gotten worse. I did a 35 mile ride and it clocked 42 miles; added a bunch of zig-zags that I didn't ride. Currently unusable for Strava. Hardware or software? Factory reset?
