/ itS the best way to do this.

What steps can Galaxy Watch users take to temporarily address the inaccurate 99 sleep score?

What’s Happening with Galaxy Watch Sleep Tracking?

Over the past week, a growing number of Samsung Galaxy Watch users have reported a frustrating glitch: consistently receiving a perfect, yet clearly inaccurate, sleep score of 99.This issue impacts various Galaxy Watch models, including the Galaxy Watch 5, Galaxy Watch 6, and even older iterations like the Galaxy Watch 4. Users are seeing this consistently, sometimes for days on end, despite reporting restless nights or considerably less sleep than the watch suggests. The problem isn’t isolated to one specific sleep stage; all metrics appear skewed, leading to a complete distrust of the Samsung Health sleep tracking feature.

Identifying the Symptoms: Is Your Galaxy Watch Affected?

Here’s how to determine if you’re experiencing the 99 sleep score glitch:

* Consistently High Score: You receive a sleep score of 99, even when you know you haven’t had quality sleep.

* Discrepancy with Reality: The sleep stages reported (deep sleep, REM sleep, light sleep) don’t align with how you feel after waking up.

* Duration Inaccuracies: The total sleep duration recorded by your Galaxy Watch doesn’t match your actual time in bed.

* Impact Across Models: reports indicate the issue affects multiple Samsung Galaxy Watch models, suggesting a software-related problem rather than a hardware defect.

* Recent Software Updates: Many users pinpoint the issue starting after a recent Samsung Health or Wear OS update.

Potential Causes of the Sleep Score glitch

while samsung hasn’t officially acknowledged the widespread issue as of October 2nd, 2025, several theories are circulating within the user community:

* Software Bug: The most likely cause is a bug introduced in a recent software update. This could be affecting the algorithm used to calculate sleep scores.

* sensor Calibration Issues: A less common theory suggests a problem with the watch’s sensor calibration, leading to inaccurate data collection.

* Data Synchronization Errors: problems with syncing data between the Galaxy Watch and the Samsung Health app could be corrupting sleep data.

* Third-Party App Interference: Although less probable, interference from other apps running on your phone or watch could perhaps disrupt sleep tracking.

1. restart Your Galaxy Watch: A simple restart can often resolve minor software glitches.
