Samsung Active 2: Sleep Tracking And You

The Samsung Galaxy Watch Active2 is a smart watch that comes with enhanced sleep tracking analysis. The watch uses your movement and heart rate to determine if you are awake, or in light, deep, or REM sleep phases. This data is tracked in the Samsung Health app, which can be viewed on the watch, but it is recommended to be viewed on a smartphone. The watch also comes with auto workout tracking and pace coaching features.

The Samsung Galaxy Active 2 uses movement and heart rate to determine sleep phases

The Samsung Galaxy Active 2 watch has an enhanced sleep tracking analysis feature. This feature automatically tracks your sleep by monitoring your movement and heart rate. The data is then tracked in the Samsung Health app, which can be viewed on the watch or a smartphone.

The Samsung Health app records and manages your 24-hour activity and sleep patterns to cultivate a healthy habit. It also records your exercise information and calories burned. The sleep tracking feature of the watch can be configured with other apps, such as Sleep as Android, to track sleep and trigger an input when you are sleeping.

The Samsung Health app categorizes sleep into four states: awake, REM, light, and deep. It uses your movement and changes in your heart rate to determine which state you are in. When you are awake, your heart rate is typically higher compared to when you are asleep, except during REM sleep. During REM sleep, your heart rate picks up and varies, but your brain paralyzes your muscles, making you very still.

The Samsung Galaxy Active 2 watch can occasionally mistake your current state, for example, if you are working at a desk and have your arm in a similar position to when you are laying down, it may start tracking sleep. Similarly, it may not always accurately recognize when you get out of bed or the total time you have slept.

Sleep tracking can be configured with apps like Sleep as Android

The Samsung Galaxy Active 2 watch has enhanced sleep tracking analysis, which uses your movement and heart rate to determine if you are awake, or in light, deep, or REM sleep phases. This data is tracked in the Samsung Health app, which can be viewed on the watch but is recommended to be viewed on a smartphone.

To track your sleep with the Sleep as Android app, you will need to manually tell the watch that you are sleeping. This can be done by going into the app and triggering an input boolean.

It is worth noting that sleep tracking will occasionally start when a person is awake. For example, someone working at a desk may have their arm in a similar position to when they are laying down, and the watch will start tracking sleep.

Samsung Health records and manages 24-hour activity and sleep patterns

The Samsung Health app, available on the Galaxy Watch Active2, records and manages your 24-hour activity and sleep patterns to help you cultivate a healthy lifestyle. The app has an exercise feature that allows you to record your exercise information and calories burned. It also has a sleep tracking feature that uses movement and heart rate data to determine whether you are awake or in light, deep, or REM sleep phases. The sleep tracking feature is also capable of differentiating between the four stages of sleep: awake, REM, light, and deep sleep.

The Galaxy Watch Active2 will notify you when it recognises that you have been inactive for more than an hour, and it will suggest some stretching exercises for you to do. It can also detect when you are driving and will not display any notifications or suggestions during this time. The watch can also track the number of steps you have taken and the distance you have travelled. To access this data, tap on the Samsung Health icon on the Apps screen and swipe up or down to access the steps tracker screen.

While the Samsung Health app is generally effective at tracking sleep, some users have reported issues with its accuracy. For example, the watch may occasionally mistake a person's awake state for sleep, especially if they are very still, such as when working at a desk. Additionally, some users have reported that the watch tends to underreport the amount of deep sleep they get. It is important to note that sleep tracking on a watch can be hit or miss, as it infers the stage of sleep based on movement and heart rate rather than brainwave patterns.

To improve the accuracy of sleep tracking, some users have suggested using additional apps, such as Sleep as Android, which can listen for snoring and movement to estimate sleep patterns more effectively. It is recommended to view the sleep data on a smartphone rather than the watch, as the larger screen provides a better visualisation of the data.

The Samsung Health app has been updated to fix sleep tracking issues

The Samsung Galaxy Watch Active2 is designed to track sleep automatically. It uses movement and heart rate data to determine whether you are awake or in light, deep, or REM sleep phases. This data is then tracked in the Samsung Health app, which can be viewed on the watch or a smartphone.

Samsung has acknowledged that its Galaxy Watches, including the Galaxy Watch Active2, have experienced issues with sleep tracking. In some cases, sleep-related measurements were not accurately reflected in the Samsung Health app. The company has provided several troubleshooting suggestions for users facing these issues.

One recommended solution is to restart or reset the watch. Users have also been advised to update to the latest version of the Samsung Health app, which may include fixes for sleep tracking problems. This update can be downloaded from the Galaxy Store or the Play Store on the watch.

It appears that the updated Samsung Health app has resolved sleep tracking issues for some users, with reports of improved accuracy in detecting different sleep stages. However, others have continued to experience problems, such as missing sleep scores, even after reinstalling the app and restarting their devices.

If you are experiencing sleep tracking issues with your Samsung Galaxy Watch Active2, it is recommended to try the suggested troubleshooting steps and stay up-to-date with app updates.

The watch's sleep tracking occasionally mistakes stillness for sleep

The Samsung Galaxy Active 2 watch has an automatic sleep tracking feature that records your sleep based on your movement and heart rate. It can track the four stages of sleep: awake, REM, light, and deep. However, some users have reported issues with the accuracy of the sleep tracking feature, especially in differentiating between being awake and asleep.

The watch occasionally mistakes stillness for sleep, which can lead to inaccurate sleep tracking data. For example, if a person is working at a desk and their arm is very still and in a similar position to when they are lying down, the watch may incorrectly start tracking sleep. This is because the watch infers the stage of sleep based on movement and heart rate, rather than brainwave patterns, which are more indicative of the actual phase of sleep.

While the Samsung Health app has undergone updates to improve sleep tracking, some users still report issues with the accuracy of the feature. For instance, some users have mentioned that the watch often records only a few minutes of deep sleep, which seems unlikely and inconsistent with their daily functioning. Others have noted that the watch struggles to recognize when they get out of bed, resulting in incomplete sleep tracking data.

To improve the accuracy of sleep tracking, users can try resetting the watch, ensuring constant HR monitoring, and adjusting the wrist position and tightness. Additionally, using a dedicated sleep tracking app, such as "Sleep as Android," in conjunction with the watch may provide more reliable results. It is important to note that sleep tracking on wearable devices is still evolving, and occasional inaccuracies may occur.
