On January 5th, during a ride, my GPS started going wonky. It would drift over to roads I wasn't on and start recalculating routes. I'd be going down the highway and suddenly the GPS would show me flying over the zoo. It happened to me and another Uber driver who lives in our housing development. According to pas it's happening to a lot of drivers here. Turns out there's a known bug in Samsung and certain other phone models (Nexus 5 for sure) where one set of satellites is 8 seconds off on their timing. You can read about it here. https://www.reddit.com/r/nexus5x/comments/5lm6l8/5x_keeps_getting_gps_location_wrong/ The fix is updating to Android 7.1.1. Since then my GPS has been working properly. You might have to sign up for the Android beta, upgrade, then go back and remove yourself from the beta testing. Warning: You'll have to rebuild your apps and data from scratch. It's like a whole new OS.
