Sleep Tracking not working(it works but its highly inaccurate)

[My-tone155115]

After many months of trying to fix this, its still not accurate. I really should give up because its so frustrating trying to get it to work only to be disappointed. Shame on Samsung. This is a major reason why I have the phone and a galaxy watch 5 pro. I've called tech support several times and tried different things, to no avail.

I also had problems when I had my s23 ultra. I switched to the new phone in February 2024.

My current phone is a Galaxy S24 Ultra 1gb unlocked.

Any suggestions would be appreciated.

My Active4 was giving funny numbers after an update several months ago, but seems to have settled down (most of the issues were in deep sleep tracking). How long have you had your watch, and been wearing it at night to track sleep?

I've had the Galaxy Watch5 Pro since August 2022. I used it with my s22, and now my s24. I wish I could get it to work reliably.

OK, it seems I've found the solution, for now. Follow these instructions: I didn't do Fix 9. I did 1 through 8. Then I slept on it. It tracked perfectly. I didn't need to reset the watch.

1. Clean your watch and wrist

Ensure that the BioActive sensor on the bottom surface of your watch is not blocked by dust or sweat. Clean it gently with a soft cloth.

2. Charge your watch before sleep: Make sure your watch has ample charge before you go to sleep to prevent it from shutting down mid-sleep.

3. Try wearing the watch differently

Try wearing the watch on a different wrist or higher up your sleeve to see if it improves the accuracy of the sleep tracking.

Fix 1: Restart your Watch

Restarting your watch can help fix lingering issues that might have been caused due to a recent update to the Samsung Health app or your watch itself. Here’s how to do it.

1. Press and hold the Power button on your Galaxy Watch. 

2. Tap on the Power icon at the top.

3. Once your watch has powered off, press and hold the Power button again to turn it back on. 

Fix 2: Allow Sensor Permissions 

Make sure that the Samsung Health app, responsible for sleep tracking, has all the necessary permissions to access the watch’s sensors. This is crucial for accurate sleep tracking. Here’s how you can check and adjust these permissions.

1. Swipe up from the bottom of your watch face to open the app drawer.

2. Tap on the Settings app.

3. Tap on Security and privacy.

4. Tap on Privacy > Permission manager.

5. Under Permission manager, tap on Sensors.

3. Scroll down and tap on Settings.

4. Then, tap on Heart rate and select “Measure continuously.”

5. Tap on Sleep and turn on “Blood oxygen during sleep.”

Fix 4: Turn On Sleep Mode

Enabling Sleep/Bedtime/Goodnight mode on your Galaxy Watch can help optimize sleep tracking since it prevents your watch from getting turned on accidentally during the night. It also helps you have a better sleep.

1. Swipe up from the bottom of your watch face to open the app drawer.

2. Tap on the Settings app.

3. Tap on Modes.

4. Select Sleep mode.

5. If you are sleeping now, toggle Turn on now.

6. Use the schedule option below to set it to turn on at a specific time.

Fix 5: Allow Data Permission for Samsung Health 

Make sure that Samsung Health has permission to access data from other apps and sensors. This should help improve the accuracy of your sleep tracking. Here’s how you can check and adjust these permissions.

1. Swipe up from the bottom of your watch face to open the app drawer.

2. Tap on the Samsung Health app.

3. Scroll down and tap Settings.

4. Then, scroll down again and tap Share data with devices and services.

5. Tap on Health Platform.

6. Turn on the toggle next to Allow all. If you don’t want to allow it all, scroll down and turn on the Sleep toggle.

7. Finally, tap Done.

Fix 6: Clear Samsung Health Cache 

Clearing the cache of the Samsung Health app can resolve any temporary data or settings issues that might be affecting sleep tracking. Here’s how you can do it.

2. Tap on the Settings app.

3. Scroll down and tap on Apps.
