First night I went to bed at 2am, got up at 7am, The sleep tracker said I went to sleep at 10:15pm. I was walking around at that time.
Second night, I purposely looked at it after I woke up, it looked like it measured my sleeping time correctly.
Later i checked it and it was completely wrong, it changed it to have extra hours. it says I was in REM sleep when I was walking around.
Is it randomly making up information? How can I trust any readings from the watch.
The Fitbit I had before this worked perfectly well tracking sleep. if the Garmin is just making stuff up, I'll return it
