Understanding sleep data
Sleep data is created on your Samsung Galaxy Watch when you wake up. The data is then transferred to your paired mobile device for processing. Once the data is processed, a sleep record is created, which is then synchronized to Health Connect and can be viewed in the Samsung Health app.
To view your sleep data, open the Samsung Health app on your phone and tap the Sleep tracker. Here, you can view various data points, including your sleep score, sleep time, sleep stages, blood oxygen levels, and snoring data. Your sleep score shows how long you spent sleeping, while your sleep time is displayed in hours and minutes, along with the calories burned. The sleep stage data shows how much time you spent in the Awake, REM, Light, and Deep sleep cycles.
The Samsung Health app also provides daily goals and coaching programs based on your sleep data to help you develop healthier sleep habits. It compares your data to previous days, allowing you to track how your daily routine improvements are influencing your sleep quality. Additionally, the app can measure your blood oxygen levels during sleep, and if you have a Galaxy Watch5 or higher, it can also track your skin temperature.
If you own a Galaxy Gear watch, you may need to install a companion app on your watch to connect with the Sleep app.

Troubleshooting sleep tracking
Check your watch's settings and connections
Ensure that your watch is securely fastened to your wrist and that the BioActive sensor on the bottom of your watch is not blocked by dust or sweat. Gently clean the sensor with a soft cloth if necessary. Check that your watch is charged before you go to bed, and make sure that it is worn snugly on your wrist throughout the night. You can also try wearing the watch on the opposite wrist or higher up on your sleeve to improve accuracy.
Check your Samsung Health app
Open the Samsung Health app and ensure that sleep tracking is enabled. Check that the app has all the necessary permissions to access the watch's sensors and data from other apps. You can do this by swiping up from the bottom of your watch face to open the app drawer and adjusting the settings. Make sure the app is up to date, and if issues persist, try clearing the cache.
Update your watch's software
Keep your watch's software up-to-date to ensure optimal performance. You can check for updates by swiping up from the bottom of your watch face to access the app drawer.
Restart or reset your watch
Restarting your watch can fix issues caused by recent updates. To restart, press and hold the power button. If issues persist, you can try resetting your watch as a last resort. Note that this will erase all data, settings, and downloaded apps, so be sure to back up your data before proceeding.
Check your heart rate tracking
Some users have reported that switching their heart rate tracking to continuous and then back to 10-minute intervals helped resolve sleep tracking issues.
Contact Samsung Support
If none of the above methods work, you may need to contact Samsung Support for further assistance or consider replacing your watch if it is still under warranty.

Using third-party apps
Although Samsung Health is the default app for sleep monitoring on the Samsung Galaxy Watch, there are several third-party apps available that can provide additional features and functionality for tracking your sleep. Here are some tips and instructions for using third-party apps to track your sleep on the Samsung Frontier:
Firstly, ensure your Samsung Frontier is compatible with the third-party app you wish to use. Some apps are designed specifically for certain models, such as the Galaxy/Gear Add-on for Sleep, which is designed for models running Tizen OS and requires the Gear companion app to be installed.
One popular third-party app for sleep tracking is Sleep as Android, which offers automatic sleep tracking and provides detailed sleep stats, including a sleep graph showing deep and light sleep periods. This app can be used with the Samsung Gear S3, which is similar to the Samsung Frontier in terms of design and features.
Another option is the AutoSleep app, which provides in-depth data and analysis of your sleep, including sleep quality, heart rate, and deep sleep metrics. It can be used with or without an Apple Watch, offering flexibility for users who prefer to track their sleep without wearing a device.
To use these third-party apps effectively, follow the instructions provided by the app developer. This may include granting specific permissions, wearing your device to bed, and syncing your data with the app to view your sleep patterns, stats, and insights.
By exploring these third-party options and following the setup instructions, you can utilise additional features and gain more insights into your sleep patterns with your Samsung Frontier.
