Sleep Feature in Samsung Health

[GaymerPlayer50]

I've done every thing I've found online, on Samsung sites, user recommendations, YouTube.. 

No matter what settings I've changed (which I've never had to do before) the sleep tracking just isn't working anymore. If it records anything it's maybe an hour at best. But most nights it just says I never slept. Was spot on until several months ago. What changed? It needs to be fixed. Obviously plenty of other people are also having the same issue and it's effecting a lot of the other scores that Samsung records. Like Energy for one. 

For a person with insomnia that part of the app was really helpful. Thought maybe it was because my old watch was to old. So I upgraded. And the same issue still persists exactly as it was with my watch 4. 

I'm going to have to switch brands if this isn't fixed. Sleep is literally the main reason I use the watch at all. 

(Yes, I've been wearing it tightly over night) 

Hopefully they're working on something.

@GaymerPlayer50 What watch are you currently using?

Have you tried wiping the back of the watch to ensure that the sensors aren't blocked? 

[GaymerPlayer50]

6 classic now. I clean the back every time I charge it (which is every other day just before bed) but if it was just sensors wouldn't it have at least worked when I first got this watch?
I'll going to be upgrading to the 8 soon if this gets fixed. I only got the 6 because it was suppose to still work with every thing. Just to see if it was my previous watch being to old.

@GaymerPlayer50 Every time? How are you cleaning it? All you should need is a microfiber. 

I don't work in a dirty environment but I have to admit that I rarely clean off the sensors.

[GaymerPlayer50]

General daily sweat and just dirt from the day. Like weekends and yard work.
I'm in the habit already because I also have hearing aids that get cleaned every time they come off of me.
If my watch is to gross I use the same alcohol pad I use in my hearing aids. Other than that it's just the same cloth I use to clean my phone screen with.

Watch4 is old tech. Even though it received the One UI 8 update, it's final update, it still can't take advantage of all the features that newer hardware has to offer and, I suspect, is the reason for the issue you are having.

Not sure if it helps but I have an 8 Classic and have still been experiencing issues with the sleep tracking. It started on my Watch 7 on 5/30/2025 and I'm experiencing them on my new watch as well. Scores are typically 20-25 (used to be between 70-90) with lots of gaps in the sleep record.
