Updating your Fitbit Flex 2

We occasionally make free feature enhancements and product improvements

available through firmware updates. We recommend keeping your Flex 2 up to date.

When a firmware update is available you’ll see a notification in the Fitbit app

prompting you to update. When the update starts, the lights on Flex 2 flash and a

progress bar appears in the app. You’ll see a confirmation message in the app when

the update is done.

Note: Updating your Flex 2 takes several minutes and may be demanding on the

battery. For this reason we recommend updating while your tracker is fully

charged or plugged into the charging cable.
