Versa 3 is not tracking my GPS accurately

[Robogk]

I bought my Versa 3 about 9 months ago and the GPS tracking was fine.

The unit was replaced under warranty about 3 months ago and since then the GPS tracking is appalling it shows me staggering about all over the place and apparently I can even walk on water to cross canals and rivers.

What can I do?

Other family members have Apple Watches and I’m under pressure to ditch the Versa 3

Hi there, @Robogk. Welcome to the Fitbit Community Forums. I'm sorry to hear that your Versa 3 replacement is not tracking your GPS data accurately. I understand how important it is to you to get accurate details and how you must be feeling over this. I'll be glad to help you with this! 

If you feel that your step count and distance are inaccurate, confirm that the following are set correctly in the Fitbit app:

• Your wrist settings (For more information, see Does the wrist I wear my device on affect accuracy?)
• Your height (For more information, see How do I manage my Fitbit profile?)

Fitbit Versa 3 calculates distance by multiplying your walking steps by your walking stride length and multiplying your running steps by your running stride length. We estimate your stride lengths using your height and sex. Track one or more runs using on-board or connected GPS, we evaluate that data to automatically update your running stride length. For best results, run at a comfortable pace for at least 10 minutes.

However, if you prefer to measure your walking and running stride lengths yourself and enter them manually, see How do I measure and adjust my stride length?

Note that when you're tracking an activity with GPS, Fitbit calculates your distance using GPS data rather than steps. If you begin moving before you get a GPS signal, the tracker will calculate distance using steps and stride length as described above until a GPS signal is found.
