Sleep tracking is not accurate on Galaxy Fit 3?

[AlanSlade]

Good morning everyone. 

I noticed that my Galaxy fit 3 is not very accurate on tracking my sleep. 

Yesterday I went to sleep at 10:45 PM, and it started tracking my sleep from 1:00 AM. It's not loose on my wrist, so the monitoring should be accurate. Anyone has the same problem?

I'm having the same problem. Recently bought Fit3, latest plugin and firmware, original Galaxy A13. I wish they would fix that, or else I'm buying from other brands next time.
