Problem #1: Pairing issues

Difficulties right off the bat are never a good sign for any smartwatch. Luckily, you may face a simple Bluetooth issue during the pairing process. Here’s what to do if your Samsung smartwatch won’t pair or if Bluetooth keeps disconnecting.

Potential solutions:

  • First, Samsung suggests switching Bluetooth on and off on your smartwatch.
    • Tizen Galaxy Watches: On your watch, press the Power/Home key while on the home screen, then tap Settings. Head to Connections > Bluetooth, and toggle Bluetooth off and on.
    • Galaxy Watch 4 or 5: Head to Settings > Connections > Bluetooth. Toggle it off, wait a few moments, then toggle it back on again.
    • For redundancy, we recommend you switch your phone’s Bluetooth off and on as well.
  • Ensure that your smartphone and watch are within Bluetooth connectivity range and the path between them is relatively unobstructed.
  • Restart your watch. You can find details on how to do this on your device at the foot of this article.
  • If all else fails, unpair your smartwatch from your phone.
    • Head to your phone’s Bluetooth menu and manually unpair the wearable. Restart the pairing process.

What if the Samsung Gear or Samsung Wearable app isn’t working properly?

If the Samsung Gear app or Galaxy Wearable app isn’t working properly, there are also a few quick solutions that are worth trying.

  • Update your app.
    • Try running the app normally to check for an available update.
    • If you do not see an update, restart your watch and paired phone.
    • Once your devices reboot, check again for available updates.
  • Delete and reinstall the app.
    • If an update doesn’t appear to fix the issue, delete the app from your paired phone.
    • In your phone’s Bluetooth settings, “forget” your Samsung wearable.
    • Reinstall and reboot the app.
    • Repair your devices.

Problem #2: Syncing issues

Health data garnered by your Samsung Galaxy Watch sometimes won’t sync with the Samsung Health app. What can you do?

Potential solutions:

  • Initiate a manual sync between your watch and smartphone.
    • Open the Samsung Health app on your phone, tap Menu > Settings > Sync with Samsung account > tap the switch icon. Finally, tap Sync.
  • Reset Bluetooth on your phone and smartwatch. Double-check that your devices are connected.
  • Restart your phone and smartwatch. Once both devices restart, try manually syncing once more.
  • Uninstall the Samsung Health app on your phone. Once complete, reinstall it.
  • Alternatively, you may need to unpair your smartwatch. Head to your smartphone’s Bluetooth menu and hit unpair.
  • As a last resort, back up your Samsung Galaxy Watch and perform a factory reset.
    • Open the Galaxy Wearable app on your phone. Tap Account and backup > Back up and restore > Back up data. Select which settings and apps you want to save. Finally, press Backup. Once complete, tap Done.
    • To factory reset your watch, we recommend using the Galaxy Wearable app again. These steps should be similar across all Samsung wearables. Open the app on your smartphone, tap the Home tab > General > Reset > Reset.
    • You’ll have to set up your wearable again, but this step should rule out any software-related issues.
  • If this doesn’t solve the issue, we recommend taking your device to Samsung for a closer look. There may be an underlying problem you can’t remedy yourself.

Problem #3: Charging issues

Your Samsung Galaxy Watch refuses to charge on its provided charging cradle or dock. This could be the start of a more significant issue or something that can be easily remedied within a few minutes.

Potential solutions:

  • Tick off a few practical troubleshooting boxes first.
    • Double-check that your wireless charger is connected to the wall and the plug is switched on.
    • Check for damage to the charger or the charging cable. If you find any, use an alternative.
    • Check that another appliance works in the specific plug you are using.
    • Ensure that the charging points on the Samsung Galaxy Watch and charging dock/cradle are clean and debris-free.
  • If your device still holds some charge, try rebooting your smartwatch before charging it again.
  • Suspect the dock is the issue? Try using another Qi wireless charger if you own a Galaxy Watch 6, Galaxy Watch 5, Galaxy Watch 4, Galaxy Watch 3, Watch Active 2, original Galaxy Watch, or Galaxy Watch Active.
    • If you own a smartphone that also supports wireless power share, you can use this as an alternative charging method.
  • You may need to replace your Samsung Galaxy Watch charger altogether.

What if your Samsung Galaxy Watch won’t turn on?

If your Samsung Galaxy Watch won’t turn on, leave it on the charger for an extended period. Completely depleted batteries can take extra time to power up. To turn the device on, press and hold the power/home button for a few seconds. If you still have an issue, it could be a software bug. You may need to reach out to Samsung’s service team.

Problem #4: Screen issues

If your Samsung Galaxy Watch is charging and holds power, but the display won’t switch on, you may have a significant problem. Before taking your device to Samsung for a closer look, try these possible fixes.

Potential solutions:

  • If your watch’s display has streaks, appears to be pixelated, or flickers, Samsung recommends a simple restart as an initial measure.
    • Pay close attention to your watch’s display during this process. You may need to contact Samsung if the issue persists during the reboot screen. It could be the beginning of a more pressing issue. This also rules out any apps or watch faces as the culprit.
    • However, you might need to change your watch face if you don’t notice anything until after the watch reboots. To change your face, touch and hold the watch face on the watch’s home screen > tap Remove > tap the checkmark to uninstall the face. This is consistent across both Tizen and Wear OS Galaxy Watches.

Other issues:

  • If your smartwatch’s screen doesn’t respond to gestures, double-check if raise-to-wake is switched on.
    • To do this on your phone, open the Galaxy Wearable app, tap Advanced, and tap the toggle next to Wake-up gesture to enable raise-to-wake.
    • For a  Tizen Galaxy Watch, open the Settings app > Advanced > Wake-up gesture > toggle on Wake-up gesture.
    • On the Galaxy Watch 4 or 5 go to Settings > Display > Screen wake-up > Raise wrist to wake.

Problem #5: Notification issues

Smartwatches aren’t smartwatches without notifications support. Sometimes, your phone won’t send messages and alerts through to your wrist. Here are a few possible remedies.

Potential solutions:

  • First, restart both your smartphone and smartwatch.
  • Check if notifications are enabled in the Galaxy Wearable app. To do this, tap on Notifications on the app’s home screen and ensure the master toggle is switched on.
    • If certain apps aren’t sending through notifications, you can toggle on notification support for individual apps on this page, too.
  • Still no luck? Check if any power saving or alert restriction modes are activated on your Samsung Galaxy Watch.
    • Tizen Galaxy Watches: Open the Settings app on your watch and head to Advanced. Ensure that Goodnight mode, Theatre mode, and Do not Disturb are all switched off.
    • Galaxy Watch 4 or 5: These toggles are available in Settings > Advanced features. You can also toggle these features off in the Advanced tab on the Galaxy Wearable app on your smartphone.

Problem #6: Update issues

Software updates are important to keep your smartwatch running smoothly. These include the latest security patches, bug fixes, and new features. However, updates sometimes refuse to install or introduce new issues to the mix.

Potential solutions:

  • As always, restart your watch and smartphone.
  • If your Samsung Galaxy Watch isn’t automatically updating, initiate a manual update. Open the Galaxy Wearable app on your phone, head to Watch software update, tap on Download and install.
  • Try unpairing and repairing your watch to your smartphone. If your phone downloads an update but can’t install it on your watch, there may be a connectivity issue between the devices.
  • If this doesn’t solve the problem, you may have to factory reset your smartwatch.
  • If your Samsung Galaxy Watch still refuses to install updates, you may need to take it to Samsung.

Problem #7: Activity tracking issues

Fitness tracking tools are only useful if they work. Samsung is moving in the right direction on its latest watches, however, they still have their fair share of glitches. Is your Samsung Galaxy Watch failing to track your workouts automatically?

Potential solutions:

  • Tizen Galaxy Watches: Head to Samsung Health > Settings > Workout detection. Ensure this setting is toggled on. Importantly, automatic workout detection will only switch on after 10 minutes, so if your workouts are shorter, this could be the issue.
  • Wear OS Galaxy Watches: Head to Samsung Health > Settings > toggle on Auto detect workouts.
  • You can also check if this feature is enabled on your smartphone. Open Galaxy Wearable on your phone, and head to Health settings > Workout detection.
  • Notably, this feature can also be the root of other issues. If you find your watch records erroneous data or suddenly starts recording a dynamic workout, you may need to switch off automatic workout detection.
  • Check for any updates to rule out (or remedy) a software problem. Ironically, software updates can also introduce more issues. If you suspect an update is at fault, you may want to factory reset your smartwatch.

Other issues:

  • As for sleep tracking, Samsung Galaxy Watches can use your heart rate or body movement to record sleep.
    • Open the Samsung Health app > Sleep > Settings > toggle on Record REM sleep to use heart rate-based tracking. If you feel this mode is inaccurate, switch it off to use body movement as the primary recording metric.
    • If you own a Samsung Galaxy Watch 3, it will automatically toggle between the two to best measure your sleep cycle.

Problem #8: Error codes

There are a few common error codes that can appear if your device is having a specific issue. Below are the most common error codes and their potential solutions. The most common error codes are typically related to setting up a mobile network. If these directions do not work for your device, reach out to Samsung’s help desk for more specific instructions.

  • 2001: App not communicating with network service details.
  • 3001: Cannot complete activation.
  • 4002: Update software.
  • 5000: Unable to set up mobile plan.

Potential solutions:

  • Verify both your phone and the Galaxy Wearable app have installed the latest available updates.
  • Uninstall the app and restart your phone and wearable. Then, reinstall the app and pair your watch (do not restore from backup, set up new).
  • If you are unable to activate your network during setup, choose skip to pair your watch and phone, then check for and install updates, including any app updates.
    • Set up your mobile plan through the Galaxy Wearable app on your paired phone. Follow the in-app instructions.
  • A mobile network QR code can only be used one time. If you cannot set up your network using a QR code, contact your carrier to obtain a new code.
  • If any issue persists, contact your mobile network provider with your error code.

Problem #9: Cellular issues

Some Samsung Galaxy Watches feature support for LTE. They’re excellent for streaming music while running or placing calls from your watch. But occasionally, your watch may fail to connect, or you may have trouble setting up the service.

Potential solutions:

  • First, ensure your smartwatch is an LTE model.
  • If you’re setting up your Samsung Galaxy Watch, double-check if your smartwatch is compatible with your phone and watch. Presumably, you own an Android device with at least 1.5GB of RAM running Android 5.0 or newer. However, your mobile network might not play nice with your watch.
    • To activate LTE on your watch, ensure your smartwatch is paired with your phone. Head to the Galaxy Wearable app > Mobile networks. The app will scan for LTE networks. Once complete, follow the prompts.
  • If connectivity on your watch suddenly fails, try restarting your smartwatch and mobile phone.
  • Are you still experiencing issues? You may need to reset your watch’s network settings.
    • Tizen Galaxy Watches: tap the Power/Home key > Settings > Connections > Mobile networks > Mobile plans. You’ll then need to follow the prompts. Tap Reset once complete.
    • Wear OS Galaxy Watches: Tap Settings > Connections > Mobile networks > Access Point Names > Reset.
    • You can also reset your watch’s network settings from your phone’s Galaxy Wearable app. Once complete, add the details of your mobile plan to your device.

Galaxy Watch 4 specific solutions:

  • If your Galaxy Watch 4 won’t connect to your cellular network, verify that you have one of the following models: R865U, R875U, R885U, and R895U. Once you confirm that you have an LTE model, follow the steps above.
  • Some users site overheating issues with Galaxy Watch 4 LTE models. To avoid this issue, place and accept calls when your watch is connected to your phone via Bluetooth rather than in standalone mode.
    • Limit the use of LTE services to areas with a strong LTE signal.
    • Keep your watch software updated.
    • We recommend contacting Samsung for assistance if the issue persists.

Problem #10: Samsung Pay issues

Samsung Pay is a highly convenient way to pay for items without physical cards. However, the service doesn’t always run perfectly smoothly.

Potential solutions:

  • We recommend that you try restarting your smartwatch and smartphone before taking any additional steps. If this doesn’t work, unpair and pair your smartwatch and smartphone.
  • Still nothing? Try uninstalling the Samsung Pay plugin. Head to the Settings menu on your phone > Apps > Samsung Pay (Watch plugin) > Uninstall. Tap Ok to confirm.
    • Once complete, reinstall the plugin from the Google Play Store or Samsung Galaxy Store.
  • Try using Samsung Pay on your smartphone.
    • If it works, you can rule out a direct issue with your bank card or the service itself. If it doesn’t, try removing and adding your bank card to the service.
  • Finally, if all else fails, you may have to reset your smartwatch.

Problem #11: Band issues

Samsung’s smartwatches come with several band options. The Galaxy Watch Active 2, for instance, ships with silicone straps, while the Galaxy Watch 3 comes with leather straps. Both materials can suffer wear and tear. If your watch band does fail due to a factory defect, check if it falls within Samsung’s warranty period. In the US, Samsung’s wearables are covered by a one-year warranty.

Problem #12: Performance issues

Newer smartwatches generally suffer from performance issues later in life. This can manifest as lag, glitching, or battery drain. You can alleviate these issues to some extent.

Potential solutions:

  • Before you take any drastic steps, try restarting your smartwatch if you haven’t done so in a while.
  • Next, uninstall any apps you aren’t using.
    • It’s easier to do this from your phone. Open the Galaxy Wearable app and head to Apps > Manage apps. Uninstall whatever you don’t need or use regularly. This should free up storage space, reduce background RAM usage, and improve battery life.
  • The watch face you’re using might also be the culprit. Try switching to a default face.
    • Touch and hold the watch face and swipe across the screen to select another face.
    • You can also uninstall any faces you no longer use. To do so, touch and hold the watch face on the watch’s home screen, and scroll between the faces. Tap Remove to delete a face you no longer use, then tap the checkmark to uninstall the face. This method is consistent across Tizen and Wear OS Samsung Galaxy Watches.
  • Check for software updates. If there’s a fundamental software issue with your device, an update will likely fix it. This is especially true if you haven’t updated your device for some time.
    • Of course, a new update could also be the culprit. In this case, you may have to reset your smartwatch.
  • If all else fails, you might need to take your smartwatch to Samsung for a closer look.
