Fitbit Versa 4 Restart And Factory Reset: Step-By-Step (2026)

Your Fitbit Versa 4 is frozen, will not sync, or is acting strangely, and you need to know whether to restart it or reset it.

A restart is quick and safe, while a factory reset erases the watch, so the order matters.

This guide covers both, and the restart takes about 15 seconds.

Restart or factory reset? Quick answer

Option	Time	Erases data?	Use it when
Restart (hold button)	10 seconds	No	Frozen, laggy, not responding
Update and re-sync	Up to about an hour	No	Sync or firmware trouble
Factory reset	A few minutes plus setup	Yes	Last resort, or before selling

What order should you try?

How do you restart a Fitbit Versa 4?

Google’s help page says to press and hold the button for 10 seconds until the Fitbit logo appears, then release.

1. Press and hold the side button.
2. Keep holding for 10 seconds.
3. Release when the logo appears and wait for the watch to start.

Google states that a restart does not cause loss of activity data.

Can you restart from the watch menu?

Google’s restart page lists only the button method for the Versa 4, so use the button hold if the screen is unresponsive.

If your watch is frozen, the button hold works even when the touchscreen does not, which is why it is the better first step.

Step 2: restart the phone and reset Bluetooth

If the problem is syncing or connection, restart the phone too.

• Force quit the Fitbit app, then reopen it.
• Toggle Bluetooth off on the phone for at least 10 seconds, then back on.
• Keep the watch close, within 2 to 3 feet of the phone.
• Turn off Bluetooth on other nearby devices while pairing.

Does the watch need an update first?

Google advises charging to at least 50% before a firmware update, and 75% or higher is safer.

Keep the app running in the background, because an update can take up to an hour.

Step 3: remove and re-pair the watch

For persistent trouble, Google suggests removing the device from the app, forgetting it in the phone’s Bluetooth settings, then setting it up again.

On Android you can also clear the app cache under Settings > Apps > Health > Storage & cache > Clear Cache, as Google’s help page describes.

Google’s help pages now refer to the companion app as the Google Health app, so look for either name on your phone.

What does a factory reset erase?

Item	After reset
Apps and stored data	Removed
Personal info and saved settings	Removed
Unsynced activity, alarms, goals	Lost, so sync first
Cards for contactless payments	Removed
Suica	Not removed, so delete it in the app first

Step 4: how do you factory reset the Versa 4?

Google’s erase page groups the Versa series together, and the path it gives is the Settings app, then About, then the factory reset option.

1. Sync the watch so recent data reaches your account.
2. Open the Settings app on the watch.
3. Go to About.
4. Choose the factory reset option and confirm.

Menu wording can differ slightly by software version, so follow the on-screen prompts.

Warning: Google says to use a reset only as a last resort.

How do you open Settings on the Versa 4?

• Button route: press the side button to open the apps list, then scroll to Settings.
• Swipe route: swipe down from the top of the screen and tap the Settings cog.

Both routes come from a third-party guide, and the path inside Settings is About, then Factory Reset.

How do you factory reset a frozen Versa 4?

If the touchscreen is frozen and you cannot reach Settings, a Fitbit community moderator posted a button-only sequence.

Google’s own pages do not list this method, so treat it as a last resort.

1. Press and hold the side button for about 8 seconds, until the screen turns off and the watch vibrates, then release.
2. Immediately press and hold the button again.
3. When the Fitbit logo appears and then disappears, release the button.
4. Press and hold it once more until the watch vibrates, then release and wait for the reset to finish.

The same moderator asked users whether the watch had been unpaired from Bluetooth and the app first, so remove it there before you start.

What should you do after the reset?

• Set the watch up again from the Fitbit or Google Health app.
• Re-add payment cards if you used contactless payments.
• Reinstall apps and watch faces you use.

What if the watch shows a red X?

Fitbit community moderators suggest working through these in order for a Versa 4 that is stuck on a red X or a blank screen.

1. In the app, tap your profile picture, then your watch image, then Sync Now, and look for a firmware update banner.
2. If no banner appears, open the same watch page and tap Gallery, where the app may offer to install missing apps and recover the watch.
3. Still stuck, press and hold the side button for 10 seconds until the Fitbit logo shows.
4. As a last step, use the factory reset above.

Some users in those threads said a reset only fixed the problem temporarily, which points to support.

Which method fits which problem?

Problem	Start with	Erases data?
Frozen screen	Hold the side button for 10 seconds	No
Won’t sync or connect	Restart phone, toggle Bluetooth, re-pair	No
Red X or blank screen	Sync Now, then Gallery recovery	No
Frozen, Settings unreachable	Button-only factory reset	Yes
Selling or giving away	Settings, About, Factory Reset	Yes

Selling or giving the watch away?

Erase it first, then remove it from your account in the app so the next owner can pair it.

Google’s page covers these steps: erase a Fitbit device.

What does the Fitbit warranty cover?

Fitbit’s limited warranty covers defects in materials and workmanship for one year on a new product, or two years if you bought it in the EEA.

Certified refurbished products carry 90 days.

• Not covered: accidents, misuse, unauthorized repairs, third-party parts and cosmetic damage.
• Claim steps: request a return authorization through Fitbit Customer Support before shipping.
• Before you ship: back up your data, since it is likely to be lost during service.

When should you contact support?

If a restart does not fix the problem, Google says to contact Customer Support.
