New updates are being added at the bottom of this story…….

Original story (published on January 20, 2022) follows:

The Galaxy Watch 4 is the latest device in Samsung’s smartwatch series. The new generation includes a lot of new features along with other classic ones, like the deep sleep tracking feature.

But, it seems that many Samsung Galaxy Watch 4 users are not happy with how deep sleep tracking works. It seems there are multiple issues related to data collection (1, 2, 3, 4, 5, 6, 7, 8).

More specifically, the deep sleep data captured by the watch is incorrect or inconsistent. Meanwhile, for other users, the feature is not even working (1, 2, 3, 4, 5, 6).

Galaxy Watch 4 deep sleep tracking not working

According to reports, some users are suffering from a deep sleep tracking not working issue. So, their smartwatches are unable to get these metrics while the user sleeps.

Sleep Tracking not working Galaxy Watch4

On my galaxy watch 4, which I bought yesterday, my sleep tracking is not working. I have enabled only blood oxygen, not snore detection, and only sleep time and calories burned are shown. No sleep score, no stages of sleep shown. Is my watch not updated properly, or what can I do to fix this issue?


Incorrect or inconsistent deep sleep data issue

On the other hand, related reports indicate that, although the feature is working, the watch suffers from an incorrect or inconsistent deep sleep data issue.

Fitbit sleep tracking Vs Samsung health on the galaxy watch 4

Which is more accurate? I’ve had Fitbit watches for the last 5 years, the Fitbit sleep tracker seemed to track a lot more deep sleep on average than the Samsung watch. Since I’ve had the Samsung watch I’m getting about 20-30 minutes deep sleep compared to on average 60mins deep sleep most nights with Fitbit.


How accurate is the sleep tracking on the GW4?

I’ve been tracking my sleep for about 11 days now, and I have been consistently way below the average for deep sleep, and way above the average for light and awake. Is that anything to worry about, or is the tracking just not accurate?

Therefore, it is useless for the deep sleep tracking feature to be working, if all the data it records is not accurate, since it negatively affects all the data obtained in general.

At the moment, there doesn’t seem to be an official acknowledgment from Samsung about the deep sleep data issues on the Galaxy Watch 4. So, it’s not known if they’re aware of the issue.

However, rest assured that once new updates related to the matter arise, we will update this article to keep you informed.
