Has anybody got the O2 meter to monitor your O2 at night to actually work. ???? If so please help.
Yes, you have to open the Samsung Health app on the watch and scroll down to settings and go to "Measurements" and under "Blood oxygen during sleep" you pick "Measure constantly" - by default it's set to "Don't measure" even if you set it up everywhere else.
You don't get this option? Remember it's on the watch, not the phone:
Open Samsung Health app on the watch - done
Scroll down to settings - done
Pick "measurements" - no, there is no menu called that. Only "units", "Workout detection", "Inactive time alerts", "HR and stress measurements", "Data permissions" and "help".
It feels like there is a chunk of options missing.
