Galaxy Watch series devices: Sleep Tracking Issue with latency and deep sleep not recording

[Claybies]

I've tried searching for this but all I could find is that the sleep tracking is fixed on the new watches. Not in my case though.

I have an S24 Ultra (not sure if that even matters) and the new Galaxy Watch 8 Classic.

On May 30th, I updated the Samsung Health app on my old Galaxy Watch 7. Since then my sleep has not recorded right. I experience gaps and the sleep tracking ends before I'm awake.

It seems like this wouldn't be a hardware issue since it started on my Watch 7 and has continued to the Watch 8, but here's a list of things I've tried:

- Cleared cache for all health apps on both the phone and watch

- Factory reset on Watch 8 (twice)

- Uninstalled and reinstalled Samsung Heath on both the phone and watch

- Turned on then off any battery/power saving modes (also set apps to "unrestricted")

- Set heart rate to measure constantly

- Turning sleep mode on both manually and using a schedule

Tech support said I may have to send the watch in for repair, but I've had it for less than 2 weeks so that seems ridiculous. Any help would be greatly appreciated!

I've included screenshots of what I'm seeing along with the clear decline after 5/30:

I don't know what everything "they" said is.  I assume you mean tech support.  Did you clear the watch's cache partition and the cache of the health app for good measure?  Did you make sure the back of the watch is cleaned of skin oils?

Hi all,

 I have the Galaxy Watch 4 and I've being using it for years for sleep tracking.
 Last week, my watch got "upgraded" to One UI 8.0. Since then, sleep tracking stopped working. Doesn't record anything at all. I already try resetting everything but it didn't work.
 Is anyone having the same issue? Any suggestions?

Thank you!

This has been happening to me too. Any answers?

Same issue still hasn't been resolved, no update and not responding to theze queries as well, ignoring user issues

Same. I thought I found a workaround but then had a 2.5 hour long gap. They still claim it's movement and that it'll eventually be fixed but if I was moving for 2+ hours, my wife would've kicked me out of the bed. They also keep saying they need more data from me.
