How To Fix Fitbit Versa 4 Won’t Turn On

If your Fitbit Versa 4 screen has gone black and won’t respond to anything, you’re not alone. This is one of the most reported issues across Fitbit Community forums, with thousands of users experiencing the exact same problem — sometimes on devices that are only days old.

The frustrating part, and the reason one of our commenters was understandably angry, is that most “fixes” you’ll find online tell you to factory reset the device. But if the screen is completely dead, you can’t access the settings menu to do a factory reset. This guide addresses that directly and covers every method that actually works, including what to do when the screen is too dead to interact with.

First: Figure Out What Your Versa 4 Is Doing

Not all “won’t turn on” situations are the same. Identifying your specific symptom gets you to the right fix faster.

Completely dead — no vibration, no light, no response to anything: Your battery is either fully drained or the device has hard-crashed. Start with Method 1.

Fitbit logo appears briefly then screen goes black again: The device has enough power to attempt a boot but can’t complete the startup process. This is usually a firmware issue. Skip to Method 4.

Fitbit logo appears, then a red X appears, then black screen: This is a known firmware/boot failure state. It’s the most serious software issue and requires a specific factory reset procedure. Skip to Method 5.

Screen is black but the device vibrates when you press the side button: The Versa 4 is alive but the display has frozen. Skip to Method 3.

Screen is black but the Fitbit app still shows the device connected and syncing: The device is running fine but the screen is locked up. Skip to Method 3.

Method 1: Charge It Properly (Most People Don’t Do This Right)

This sounds obvious, but the majority of “dead Versa 4” cases are simply drained batteries that won’t show any signs of life until they’ve accumulated enough charge to boot. The mistake most people make is putting it on the charger for 10 minutes, seeing nothing on screen, and assuming the device is broken.

1. Connect the charging cable to a wall outlet USB adapter (not a computer USB port, not a USB hub, not a monitor USB port). Wall adapters provide consistent 5V power that laptop ports sometimes don’t.
2. Attach the Versa 4 to the charger. The magnets should pull the watch into position. Make sure the charging pins on the cable align with the gold contacts on the back of the watch.
3. Leave it charging for a full 2 hours. Do not touch it. Do not press any buttons. Even if the screen stays completely black the entire time, leave it.
4. After 2 hours, press and hold the side button for 10-12 seconds.
5. If the Fitbit logo appears, release the button and let it boot.

Many Fitbit Community users report that their Versa 4 appeared completely dead for over an hour on the charger before finally showing signs of life. When the battery drains to absolute zero, the device needs to accumulate enough charge to power the boot process, and it can’t display anything until it reaches that threshold.

If nothing happens after 2 hours:

Check the charger contacts. Look at the gold pins on the charging cable. They should spring up and down when pressed. If any pin is stuck down or doesn’t spring back, the charger is defective. This is a documented design issue with Fitbit chargers — the pins gradually get pushed inward over time until they no longer make contact.

Try pressing the Versa 4 down onto the charger while slightly tilting it in different directions. If you see any brief flash on screen when pressing at a certain angle, the charger contacts are the problem. Get a replacement charger ($10-15 on Amazon).

Method 2: The Proper Force Restart

The Versa 4 has one physical button on the left side. The restart process is simple but the timing matters.

1. Press and hold the side button for at least 10 seconds. Count slowly. Most people don’t hold it long enough.
2. You should feel the watch vibrate and see the Fitbit logo appear on screen.
3. Release the button as soon as the logo appears.
4. Wait for the watch to fully boot. This can take 30-60 seconds.

If you don’t feel any vibration and don’t see the logo after 10 seconds, keep holding. Some users report needing to hold for 15-20 seconds before the device responds. Fitbit’s official documentation says 10 seconds, but forum experience says longer is sometimes necessary.

If the restart doesn’t work on the first try, repeat it 3-4 times. Multiple Fitbit Community moderators emphasize that it sometimes requires several attempts before the device responds.

Try it while on the charger. Connect the Versa 4 to the charging cable, then hold the side button for 10-15 seconds. Performing the restart while charging gives the device a power boost that can help it complete the boot process.

Method 3: The Clock Face Trick (Black Screen but Device Is Alive)

If your Versa 4 has a black screen but is still communicating with the Fitbit app (the app shows it connected, synced, or shows a battery percentage), the display is frozen but the device is running perfectly fine underneath.

1. Open the Fitbit app on your phone.
2. Tap your profile picture (top left).
3. Tap your Versa 4.
4. Tap Clock Faces (or Gallery > Clocks).
5. Select a different clock face from the one currently installed. Choose one from the “By Fitbit” section for the most reliable results.
6. Tap Install.
7. Keep your phone right next to the Versa 4 and wait.

When the new clock face installs, it forces the display to refresh and reactivate. Multiple users across the Fitbit Community have confirmed this brings the screen back immediately.

If the install fails with a connection error:

• Make sure Bluetooth is enabled on your phone.
• Force close the Fitbit app completely, then reopen it.
• Toggle Bluetooth off, wait 10 seconds, toggle it back on.
• Try the install again.

Method 4: Fix the Boot Loop (Logo Appears Then Dies)

If your Versa 4 shows the Fitbit logo briefly then goes black, or keeps cycling through the logo without fully booting, the firmware is either corrupted or an update failed partway through.

Try forcing a firmware update through the app:

1. Open the Fitbit app.
2. Tap your profile picture > Versa 4 > Sync Now.
3. If a firmware update is available, a pink Update banner should appear. Tap it.
4. Keep the Versa 4 on its charger and right next to your phone during the update. Do not move either device or open other apps.
5. The update can take 15-60 minutes. Let it complete fully.

If Sync Now doesn’t trigger an update:

1. In the Fitbit app, tap your profile picture > Versa 4 > Gallery.
2. The app may show a popup to install missing apps or recover the device. Follow the prompts.
3. This can sometimes re-flash the firmware and break the boot loop.

If the app can’t find the device at all:

1. On your phone, go to Bluetooth settings and forget the Versa 4.
2. Delete and reinstall the Fitbit app.
3. Restart your phone.
4. Place the Versa 4 on its charger.
5. Open the Fitbit app and try to set up the Versa 4 as a new device.

Method 5: The Red X Factory Reset (The Fix Nobody Explains Properly)

The red X after the Fitbit logo is one of the most common and most misunderstood Versa 4 problems. It means the device can’t complete its boot sequence, usually due to corrupted firmware or a failed factory reset. Standard restart methods won’t fix this.

The problem with the normal factory reset instructions is that they require you to navigate to Settings on the watch screen, which you can’t do if the screen shows a red X and goes black. There IS a way to factory reset without the screen, but the timing is very specific.

The hidden hardware factory reset procedure:

1. Make sure the Versa 4 is on the charger and has been charging for at least 30 minutes.
2. Press and hold the side button for about 8 seconds until the screen turns off and the watch vibrates.
3. As soon as you feel the vibration, release the button.
4. Immediately press and hold the side button again.
5. Wait for the Fitbit logo to appear.
6. As soon as the logo disappears, release the button.
7. Immediately press and hold the side button again.
8. When you feel a vibration, release the button.
9. Wait for the watch to complete the factory reset. This can take several minutes.

This sequence is the hardware-level factory reset that Fitbit Community moderators walk users through. The timing of the press-release-press-release-press pattern is crucial. If you miss the timing on any step, start over from step 2.

After the factory reset completes:

The Versa 4 will restart as if it were brand new. You’ll need to set it up again through the Fitbit app. Your historical health data is stored in your Fitbit account (in the cloud) and will still be there, but any data that hadn’t synced before the reset is lost.

If the red X persists even after the hardware factory reset, the firmware may be too corrupted to recover through user-level methods. Contact Fitbit Support for a warranty replacement (see Method 8).

Method 6: The Full Battery Drain Recovery

The Versa 4 can get stuck in a state where it’s too frozen to restart but still has battery power keeping it in the crashed state. Draining the battery completely can break this cycle.

1. Remove the Versa 4 from the charger.
2. Do NOT press any buttons.
3. Leave it sitting for 24-72 hours until the battery is completely dead. If it’s frozen (not truly off), background processes will slowly drain whatever charge remains.
4. Once it’s fully dead (zero response to anything), place it on the charger.
5. Leave it charging for 2 hours without touching it.
6. After 2 hours, try the force restart (Method 2).

This has been confirmed by multiple Fitbit Community users as a fix when nothing else works. The complete power drain clears whatever firmware state was causing the lockup.

Method 7: Check for Water Lock, Sleep Mode, and Screen Brightness

These seem trivial but catch people off guard, especially the water lock issue.

Water Lock mode disables the screen and button responses to prevent accidental input during swimming or showering. If water lock is active, double-tap the screen firmly. This is the unlock gesture for water lock on the Versa 4. You may need to tap harder than you’d expect, or try multiple times. If double-tapping doesn’t work, try a long press on the side button (10 seconds).

Sleep Mode dims the screen to the point where it appears black in bright environments. Swipe down from the top of the screen to access Quick Settings and look for the half-moon icon. Tap it to disable Sleep Mode. If you can’t see anything on screen, try viewing it in a completely dark room — the screen may actually be on but extremely dim.

Screen brightness set to minimum: If you can see faint content on the screen in darkness, go to Settings > Screen Brightness and set it to Normal or Max.

Method 8: Remove Screen Protector or Case

Screen protectors and cases can interfere with the Versa 4’s ability to detect touches and button presses. Fitbit’s own support documentation recommends removing any case or screen protector before attempting a restart.

Some screen protectors also block the ambient light sensor, causing the Versa 4 to think it’s in darkness and dim the screen to minimum. Remove any protector and try the restart again.

When to Contact Fitbit Support

Contact Fitbit Support if:

• The red X persists after the hardware factory reset (Method 5)
• The device is completely unresponsive after the full battery drain recovery (Method 6)
• You see a white or green flickering screen (documented hardware defect)
• The screen shows visible moisture or condensation behind the glass
• The device is within its 2-year warranty period from Google/Fitbit

The warranty process: Fitbit will ask you to demonstrate the issue (sometimes via video) and confirm you’ve tried their standard troubleshooting steps. If the device is confirmed defective, they’ll send a replacement. Users report the process takes 5-15 days including shipping. Multiple forum users report that Fitbit has replaced Versa 4 units that display the persistent red X, as it’s a recognized failure state.

Have ready when you contact them:

• Serial number (found in Fitbit app under device settings, or on the original packaging)
• Proof of purchase
• Description of what happens with each restart method
• Note specifically if you see the red X — this is a recognized failure state that speeds up the warranty process

Fitbit Support: Go to support.google.com/fitbit and select Contact Us, or visit contact.fitbit.com. Be aware that hold times can be very long.

Why This Happens and How to Prevent It

Based on patterns from hundreds of Fitbit Community posts, the Versa 4 black screen clusters around a few triggers:

Firmware updates gone wrong. Many users report the black screen started immediately after a firmware update, or after the device attempted to auto-update while the battery was low. Always keep the Versa 4 on its charger during firmware updates and make sure the battery is above 50% before any update begins.

Complete battery drain. Letting the battery hit 0% appears to trigger firmware corruption in some units. The Versa 4’s battery management system doesn’t always handle the transition from critically low power to shutdown gracefully. Charge the device before it drops below 20%.

Third-party clock faces. Some third-party clock faces use excessive memory, leading to crashes. Note that Google removed third-party apps from the Fitbit Gallery for EU users in 2024, but if you installed any before that change, they may still be on your device. If you experience recurring black screens, try switching to a Fitbit-made clock face.

The charger itself. The stock Fitbit charger’s weak magnet and prone-to-stick pins cause inconsistent charging. Users who switch to aftermarket chargers report fewer episodes. If your Versa 4 frequently “dies” overnight even though you charged it, the charger may not have been making proper contact.

Sudden battery drain as a warning sign. Several Fitbit Community users reported unusual battery drain (going from full to dead in a few hours) immediately before the permanent black screen. If you notice your Versa 4 suddenly draining much faster than normal, restart it immediately via the side button. Don’t wait for it to die on its own — that’s often when the firmware crash happens.
