I have had the watch for 4 days. On all 3 nights it has registered my sleep fine starting around 1:30. I go to sleep at about 11:45 and wake up in about 1 hour or so on most nights. That should not matter as I am only awake for about 15 minutes or so. It tracks everything fine but totally shows nothing for that first hour. Can't tell if the phone is defective or what ... and Samsung has been useless for help. Anyone have this too or know about it?
Just switch to this watch from Fitbit Sense which always would allow me to edit start and end times for sleep span and it would adjust stats accordingly. Finding it VERY frustrating as I have a habit of lying in bed for anywhere from 10-30 min before getting out of bed, and Watch5 includes this time as part of "sleeping" BUT ironically records this as "Awake" time! On my old Fitbit I could adjust the wake time and get much more accurate stats. 😞 Hope Galaxy will change this.
