Hey everyone. I have had my Watch 4 46mm Classic since Christmas and it has tracked my sleep everynight without fail for 8 months. 3 weeks ago it stopped tracking sleep, snoring and O2 levels, the display simply shows --:-- for the time asleep. Heart rate is still monitoring all night without fail. The phone (Galaxy Note 10+) is connected and showing everything heart rates as well, but also no sleep info.
I have rebooted watch and phone, recorded sleep manually a couple of nights, changed to charge morning instead of evening, nothing. It is set to go to Night Mode automatically at 9pm, which is before I **bleep** (and always has been set this way). I am wondering if a recent update has done something weird? I loathe to factory reset and start over as the backup on these is totally useless and I would have to set everything up again from scratch.
Thanks Laura, reinstalling Samsung Health on my phone fixed sleep tracking on the watch and the phone. I have been searching and asking for over a week to fix it and glad I found this as was about to reset the watch!
Thank you both, uninstall and reinstall Samsung Health has fixed the problem. I have been searching for an answer for over a week and nothing until now! Really thought it was the watch as it was not showing on the watch either.
