Is anyone else seeing gaps in their sleep data. I'm wearing the watch as suggested, one funger above the wrist bone and snuggly. Despite this I've noticed a few instances since getting the new watch where there are gaps in my sleep data. Most recently 2 hrs of data is not recorded and the sleep start time is off by about 1.5 hrs.

Hi Silgi1,

We are very sorry to hear that you are experiencing intermittent gaps and inaccurate start times in your sleep data on your new Galaxy Watch.

To help stabilize your sleep tracking sensors, we kindly recommend attempting the following troubleshooting steps:

1. Clean the Sensor: Wipe the glass sensor on the underside of your watch with a soft microfiber cloth before bed to ensure no moisture or residue interferes with the optical light.

2. Set Continuous Tracking: Open Samsung Health on your watch, navigate to Settings > Measurement, and ensure your Heart Rate tracking is set to Measure continuously.

3. Clear App Cache: On your paired smartphone, navigate to Settings > Apps > Samsung Health > Storage and select Clear Cache.

4. System Refresh: Restart both your smartphone and your Galaxy Watch before going to sleep to clear out any lingering background software glitches.

Please try these steps over the next few nights and let us know if your sleep data stabilizes. If the gaps continue to appear, please keep us updated so we can look into this further for you!
