What You'll Learn
Check for updates on the watch and Samsung Health app
To check for updates on your Samsung Galaxy Watch Active2, you will need to use the Galaxy Wearable app on your phone. First, launch the app and tap on 'Home'. From there, you can select 'Watch software update' and then 'Download and install'. If an update is available, you can tap 'Install now'. If no update is available, your device will display the message: "Your software is up to date". To automatically download updates over a Wi-Fi network, turn on the Switch for Auto download over Wi-Fi. Please note that your watch will disconnect from your phone during the update and will reconnect once the update is complete.
You can also update your watch's apps by entering the Galaxy Store, tapping on the Watch icon, navigating to 'Menu > Updates', and then tapping on the 'Watch tab' and 'Update all'. To download individual updates, tap the Update icon to the right of the app.
To check for updates on the Samsung Health app, open your Settings and go to the 'Apps' option. Here, you can search for Samsung Health and check your app version at the bottom of the screen. Alternatively, you can tap on 'App details in store' to check the version. You can also go to the Samsung Health main screen, tap the more icon, click "Settings", and select "About Samsung Health".

Restart both devices
If your Galaxy Watch Active 2 is not syncing your sleep information to the app, you should restart both devices. This can be done in two ways:
Reboot
- Press and hold the Home/Power button until you see a Rebooting message on the watch screen.
- After a few seconds, the device will restart and display your chosen watch face.
Power Off and On
- Press and hold the Home/Power button for a few seconds.
- Select Power Off.
- Press the Home/Power button again to turn on your watch.
If your watch is freezing or sluggish, a restart may help to resolve these issues. If you are still having problems with your watch, you may want to try a factory reset. Before performing a factory reset, you should turn off the lock screen, back up your account data, and save music and photos manually.

Try a manual sync
If your Active 2 watch is not syncing sleep data to the Samsung Health app, you can try a manual sync.
First, check for updates to your watch and the Samsung Health app. If there are any updates available, install them. If everything is up to date, restart both devices (the watch and your phone). If restarting doesn't work, try a manual sync by following these steps:
- Open the Samsung Health app on your phone.
- Tap the Menu button and choose Settings.
- Tap 'Sync with Samsung account'.
- Choose 'Sync now'.
Additionally, ensure that power-saving mode, airplane mode, and watch-only mode are not turned on. On your watch, go to Settings > Battery > Power Mode and choose 'Standard' to disable these modes.
If none of these steps work, you can try uninstalling and reinstalling the Samsung Health app.

Ensure power-saving mode, airplane mode, and watch-only mode are off
To ensure your Active 2 watch is effectively tracking your sleep, it is important to ensure that power-saving mode, airplane mode, and watch-only mode are off. These modes can interfere with the watch's ability to accurately track your sleep and sync the data with the Samsung Health app.
Firstly, let's discuss power-saving mode. This mode is designed to optimise battery life and performance by reducing screen brightness, turning off background apps, and disabling certain features like Wi-Fi and location services. While this can be useful when you need to conserve battery, it is important to ensure that power-saving mode is off when you want to track your sleep. To disable power-saving mode, open the Settings menu on your watch, navigate to the Battery section, and toggle the switch to turn off power-saving mode.
Next, we have airplane mode. This mode disables Bluetooth and Wi-Fi connectivity, preventing your watch from communicating with your phone or using certain functions that rely on this connection, such as calls, messages, or playing music from your phone. Again, while this can be useful in certain situations, it is important to ensure that airplane mode is off when you want to track your sleep and sync data between your watch and phone.
Finally, watch-only mode should also be turned off. This mode may restrict the functionality of your watch and impact its ability to track sleep accurately. To turn off watch-only mode, go to Settings > Battery > Power Mode, and choose Standard mode instead.
By ensuring that these modes are off, you can help your Active 2 watch accurately track your sleep and sync the data with the Samsung Health app. If you continue to experience issues, you may need to try other troubleshooting steps, such as restarting your devices or manually syncing the Samsung Health app.

Uninstall and reinstall the Samsung Health app
If you are having issues with your Active 2's sleep tracking, it may be a good idea to uninstall and reinstall the Samsung Health app. This can be done through the settings menu on your device.
First, open the settings menu on your device. Then, find the Samsung Health app in the list of apps. If you are unable to find it, try searching for it in the settings menu. Once you have located the Samsung Health app, select it and look for the option to uninstall or disable it. If the app can be uninstalled, this option will appear in the menu. If the option to uninstall is not available, it means that the app is essential for your device to function correctly and cannot be uninstalled. In this case, you can try disabling the app, which will remove it from your apps screen and prevent it from running in the background. However, keep in mind that disabled apps will no longer receive updates.
After uninstalling or disabling the Samsung Health app, you can reinstall it through the app store or the Galaxy Store. Once the app is reinstalled, you can set up sleep tracking by opening the Samsung Health app and granting the necessary permissions. Ensure that your watch and phone are updated to the latest software version and restart both devices if necessary. If that doesn't work, try forcing a manual sync by opening the Samsung Health app, tapping the Menu button, selecting Settings, and choosing Sync with Samsung account. Additionally, check that power-saving mode, airplane mode, and watch-only mode are not turned on, as these may interfere with sleep tracking.

Frequently asked questions
To turn on sleep tracking, wear your watch to bed. If you have already set up your watch, you can still turn on sleep tracking by opening the Samsung Health app on your phone, tapping Menu, choosing Settings, tapping Sync with Samsung Account, and choosing Sync Now.
If your Active 2 is not tracking your sleep, check that you have the latest version of the Samsung Health app installed on your phone. If you do, try restarting both devices. If that doesn't work, try a manual sync. If the issue persists, check that Power Saving Mode, Airplane Mode, and Watch Only Mode are all turned off.
Sleep tracking on a watch is hit or miss. It infers the stage of sleep you are in by movement and heart rate, but it is really brainwave patterns that indicate which phase of sleep you are in. No fitness tracker is truly accurate, so sleep data should never be used for self-diagnosis.
You can view your sleep tracking data on the Samsung Health app on your phone. You can also view it on your watch.
You can use the Bedtime mode on your Active 2 to limit distractions before you go to bed. This will cancel all audio and vibration alerts except your alarm.
