Have you updated the Fitbit app and shut off/restart the phone?
Best AnswerStill hoping to find out what phone model your asking about.
I'm also not sure what you mean by attempt to pair, and what error message you recieved?
If you think back to when setting up, you never paired the tracker, you added the tracker to your Fitbit account, then the fitbit app paired the tracker to the phone.
To sync the Fitbit tracker does not need to be paired to the phones bluetooth.
If the tracker is not syncing, why would you expect any of the data to be correct?
As for how useful my answer can be, that is true, without having any details, error messages, phone model, etc I am only able to give generic info.
