Hi Lenka,
the phone is placed on the bed, right next to my pillow. My deep sleep average for last 14dys = 48%. App shows Aus avg is 43%, and a few countries show above 50% (56% highest).
How Much Deep, Light, and REM Sleep Do You Need?.
Sonar doesn’t seem to be supported on my phone (Samsung S21+ 5G - Android 14). See attached pic.
Not listed on the below list.
So sonar is a replacement for a wearable? I read the below page.

With regards to wearables, is there a preference with regard to compatibility with SaA? I’ve just taken a look at Samsung Galaxy 6 etc. I’ll continue researching a few others. Thank you.
