Samsung smart watch randomly shuts down

To force a reboot on your watch, press and hold the Home key (Power key) and Back key at the same time until "Rebooting..." displays. Do not select Power off on the screen or Restart when it appears.

The length of time you need to hold down the buttons varies by device. On some watch models, it may take up to 30 seconds for "Rebooting..." to appear.

When the Rebooting message appears, release the keys you were holding down. The watch screen will go dark, and then the watch will reboot.

If the watch is connected to your phone, the devices will temporarily disconnect during the reboot.

If you're rebooting your watch to fix a problem, be sure to check for software updates on your watch and the Galaxy Wearable app, including device plugins, once the reboot is complete.

If the watch cannot restart due to physical damage, like a stuck button, please visit the Service Center to request service.

Make sure you are using the charging dock that is designed for your watch's model. Otherwise, it may not charge properly. For example, the Galaxy Watch Active cannot properly charge or may not charge at all on the charging dock for the original Galaxy Watch.

Connect the charging dock to an approved Samsung wall adapter. Make sure you are using the same dock as the one that was included with your watch.

Place the watch on the appropriate charging dock. However, if you're using a Wireless Charging Duo Stand or Wireless Charging Pad, lay the watch flat on the charging surface with the screen facing up.

Some metal watch bands may interfere with charging, causing poor charging speed or excess heat. Remove the band while charging if you encounter these issues.

Allow the watch to charge for at least 1 hour. If the watch's charging indicator doesn't appear on the display, press the Home key (Power key) once.

• If a charging error occurs, the charger's LED will flash red or the watch screen will display a message. Remove the watch from the charger, and then properly place it back on the center of the charging surface.
• If the watch heats up while charging and powering on, disconnect the watch from the charger and close any running apps. Wait until the watch cools off before charging it again.
• Using the watch while charging may cause the battery to charge more slowly. Some features may be unavailable.

After the watch has charged for 1 hour, remove it from the charging dock. If the watch is powered off, press the Home key (Power key) to power it on.

• If the watch powers on, it needs to be charged. If it isn’t fully charged, power it off and then reconnect it to the wireless charging dock.
• If the watch fails to power on or charge after performing the troubleshooting steps above, the watch and charging dock will need service. Please visit the Support Center to request service.

Depending on where the issue occurs, it may or may not be caused by the downloaded watch face. A simple restart can resolve an array of issues with your watch. While the watch is starting up, check if the issue occurs on the startup screen or only after the watch is turned on. If the issue occurs after the startup screen fades, change or uninstall the downloaded watch face being used.

• Wear OS models: Touch and hold the watch face in question, and then tap Remove (the minus icon).
  
• Tizen models: Touch and hold the watch face in question, then tap Remove (the minus icon), and then tap the check mark to uninstall the watch face.

After you have uninstalled the downloaded watch face(s), restart your watch to ensure that the issue has been resolved.

If you prefer using the connected phone or cannot use your watch for whatever reason (like a broken button), you can uninstall apps through the Galaxy Wearable app.

1. First, make sure your phone and watch are connected.
2. From your phone, open the Galaxy Wearable app, and then tap Apps or Apps screen. Depending on the connected watch, it may be necessary to tap the SETTINGS tab.
3. On Wear OS models, touch and hold the app you want to remove. On older models, tap Manage apps.
4. Tap Uninstall or tap the Delete icon (the minus sign) next to the app you'd like to uninstall. On Wear OS, tap Uninstall again to confirm. When finished, tap Save. Remember, some preloaded apps cannot be uninstalled. If you do not see the uninstall or delete option, the app cannot be removed.

1. Press the Home key (Power key) on the watch to wake the screen, and then navigate to your apps.
2. On the Wear OS models, touch and hold the app you'd like to uninstall. On holder models, touch and hold the Apps screen.
3. On the Galaxy Watch4 series, tap Uninstall on the pop-up window, and then tap OK. Remember, some preloaded apps cannot be uninstalled. On older models, tap the Delete icon (the minus sign) next to the app, and tap the check mark to confirm.
   

Be sure to unpair the current Bluetooth connection between your watch and phone to avoid problems.

Navigate to and open Settings on your phone. Tap Connections, and then tap Bluetooth. From the "Paired devices" list, tap the Settings (gear) icon next to your watch name, and then tap Unpair.

Power off the watch, and then power it back on. While the watch is powering on, press and hold the Power key until "Rebooting..." is displayed. If you are using the Galaxy Watch3, press and hold both the Power key and Back key simultaneously.

Release the key(s), and then immediately press and release the Power key repeatedly to enter the Reboot Mode menu.

Continue to press and release the Power key until Recovery is highlighted. Press and hold the Power key to select Recovery, and then release the Power key when the screen goes dark.

After the Factory reset is complete, the watch will reboot. Once the Welcome screen appears, connect the watch to a phone with the Galaxy Wearable app, and then check if there's an available software update for the watch.

If you have a LTE smartwatch that was activated with a QR code, a new one will be required to reactivate service for the watch. Please contact your carrier to obtain a new QR code.

If you are still experiencing issues with your watch, please visit a Samsung walk-in service center or you can schedule a repair service online.
