Here is how to reset a fitbit Surge:
Step 1 – Press and hold the Home and Select buttons
(left and bottom right) on your Surge for 10 to 15 seconds, until you see the screen flash or start to dim.
Step 2 – Let go of the buttons.
Step 3 – After your screen turns completely off, wait 10 seconds and press the Home button to turn your Surge back on.
Your Surge should now work normally.
Make sure to resync your Fitbit Surge shortly after the reset so the time is adjusted accordingly.
Note that any call or text notifications you received before the restart will be deleted. If your tracker still doesn’t work after a restart, contact Customer Support.
If you experience one of the following problems, it may be fixed by restarting your tracker:
Your tracker is not syncing
Your tracker is not responding to movement
Your tracker does not respond even when in a charger
Your tracker has a battery charge but is not lighting up
Your tracker isn’t tracking your steps
Your tracker isn’t responding to button presses, taps, or swipes
