No deep sleep tracked anymore after OS upgrade on watch 4

It might be an idea to back up your watch data, and do a reset.

Possible, but the watch says: can't back up watch data (in red)

[Nab82]

It was not quick to back it up and do the reset. let see to night if the problem is solved.

Thanks

I have raised this to Samsung as my sleep metrics have completely changed and they dunt look correct including no or low deep sleep reporting

[Nab82]

I did a reset and now I have deep sleep detected during my night usually at the beginning but not as long and many as before.

Let see if Samsung will do something

Dear All,

Somehow deep sleep phases are being detected. Maybe it was a learning process from the program (or I have better night sleep 😀)

Anyway, the problem is fixed.

Cheers.
