If your Fitbit activity tracker isn’t syncing with your phone, tracking your activities properly, or responding to taps, presses, or swipes, resetting the device might resolve those problems. How you reset a Fitbit and return it to factory settings differs from device to device though, and some models don’t offer a factory reset option. To find how to reset your device, skip to the section below that matches the Fitbit model you have.

Note: A factory reset deletes all previously stored data, as well as any data that hasn't yet synced to your Fitbit account. It also resets settings for notifications, goals, alarms, and so on. A restart, which can also resolve minor problems, simply reboots the device and no data is lost (except saved notifications). Always try a restart first and use a reset as a last resort.
