Sleep tracking not working over multiple Galaxy Active 1 & 2 watches

[dj1983]

I had been using a Galaxy Active watch since Christmas and recording my sleep every night without fail. Suddenly at the beginning of March it stopped recording and saying "No Sleep Record Today". After a couple of nights I did a hard reset and it worked again for a couple of nights and then stopped again. I reset it again and it worked for two more nights then stopped. At the third reset it didn't help and still didn't record sleep.

I swapped it out for a new Galaxy Active watch. First two nights recorded sleep, then again no sleep recorded. I reset and again still no sleep. 

This time I decided it must have been a bad batch of watches so decided to exchange it for the Galaxy Active 2 watch. First two nights sleep was recorded, then no sleep. Reset the watch, cleared all the data on the galaxy wearables app and sleep was recorded for one night but the very next night no sleep recorded. 

I've called Samsung and they aren't aware of any known issues. Given I used the original for two months with no issues recording sleep and now within two and a half weeks, three different watches have all shown the same issue, there must be an issue going on but I can't seem to find someone that can advise what it is.

Has anyone else encountered this and know of a way to fix it?

Try change the watch face, to something else. I had the same problem but then after I change the watch face, it worked perfectly fine.

This did not work for me in the least. It started it when i connected to a new device. Its frustrating. What else is going to fail? As a disabled person i rely on this for hr, sleep and fall detection.
