iPhone 17 Pro GPS tracking is inaccurate and unreliable

Perhaps a long shot:

Do you have a 3rd party VPN installed, even if you are not using it? If so, delete the VPN profile in Settings/General/VPN & Device Management/VPN, then restart your device. Don't just turn it off; delete the profile. Updates sometimes "break" VPN, and it needs to be removed. If that fixes it, you can try reinstalling VPN, but probably shouldn't.

Since I’ve been using the new iPhone 17 Pro, I’ve been noticing missing sections on my Strava rides. I’ve ridden these same routes for the past five years without any issues on my iPhone 12 and 15 Pro.

It seems strange that this has started happening much more frequently since getting the new model. It may just be a coincidence, but it’s noticeable that the failures tend to occur every time I stop for a break, when the GPS signal appears to drop and never resume until one notices at the end if the ride.

I’m just curious. I don’t have a solution or possible diagnostic. However, I’ve read on multiple communities that the Strava developer is very responsive to customer concerns. Have you contacted the developer and shared your experiences? I’m not suggesting it’s his app, but rather he may be able to offer up insights that will benefit the community.

Same for me. Notice this in Maps and Google Maps and in Pokemon. Really annoying, please fix this bug….
