Hi, I'm pretty late to the reply party as this post is several months old. However, I thought I'd respond just incase anyone else hasn't figure it out. In order for your samsung watch to record snoring;
1.First, turn on snore detection. In samsung health app. It will prompt you with permission settings. click "always allow".
2. Secondly on your watch, there's a setting you need to turn on every night before you go to bed and turn off every morning in order for the phone to start recording snoring . It's called "sleep mode." If you swipe down on your watch from top to bottom, you should see the "sleep mode" button on the left-side of the "power button". It has a picture of a bed and Cresent moon. When you turn this on via watch, your cellphone screen will turn gray. This means sleep mode is activated and your phone is now recording .
The phone screen will only turn gray if it's a capable samsung phone. Be sure to turn it off once you've waken or you will miss phonecalls. Best
Thats interesting because mines never recorded without sleep mode activation so that could be due to software update changes to protect your privacy. To add to what I said above, when you turn on sleep mode, it will automatically turn on "do not disturb" feature on on the phone. I just realized that all you have to do is turn off "do not disturb" if you do not want calls, text messages, and alarm clock to be muted while recording and sleeping. Best
