Dear Samsung,
I started using the Galaxy Watch Ultra 2 for sleep tracking, and unfortunately my first experience has been very disappointing.
Yesterday was the first time I wore the watch to sleep, and it recorded absolutely no sleep data at all.
I wore it again today, and this time it detected my sleep, but the results appear to be seriously inaccurate. There are large gaps in the sleep stage data, the total sleep time doesn't match how long I actually slept, and several of the sleep values appear completely off. For example, I actually woke up at around 5:50 AM.
Seeing a sleep score of 31 and some of these abnormal looking values genuinely caused me distress before I realized that the recording itself appears to be incomplete. Please note that low power mode was off, and the Watch was updated to the latest version.
This is especially disappointing considering that sleep tracking is one of the major health features of the watch.
I also noticed a sudden impossible jump in the AGEs index on the new watch, which is way far off from the previous watches at 414. AGEs are accumulative and this cant be the case, especially since my diet yesterday was excellent.
Tomorrow night I'm going to wear both my Galaxy Watch 7 or 8 Classic and Galaxy Watch Ultra2 at the same time and compare their sleep recordings and AGEs under exactly the same conditions. I'm interested to see whether the Watch 7 or 8 Classic records the night correctly while the Ultra2 continues having problems.
I'll share the comparison results afterward.
Thank you,
Adam

We are sorry to hear about your experience with the Galaxy Watch Ultra2 sleep tracking and AGEs Index.
Please ensure the watch is worn securely with the sensor in full contact with your wrist, and restart both the watch and connected phone. Also, ensure Samsung Health and the watch software are updated to the latest available version.
Regarding the AGEs Index, the value is based on sensor measurements and analysis and may vary between devices. We appreciate your planned comparison with your other Galaxy Watch, as the results may help clarify the behavior.
