After all it's not like your watch has eyes yet to see if your eyes are open or not.
Sucks because I really wanted it to be the real deal.
I stopped using the sleep tracker a long time ago because of this type of issue. I had to constantly go into the app and change times, etc. I think it's a gimmick and, personally, I don't trust it.
I have a galaxy watch 4 with a s22 that I am ready to take back to Verizon and switch for something else. My sleep time is wrong every day. If I'm sitting reading or watching tv, even in the middle of the day, it records it as sleep and there is no longer a way to edit sleep time. I bought the watch to replace an old fitbit, but atleast I could edit sleep time on my fitbit. In searching for a solution to this in forums I have seen this had been a concern for MANY, even in the Canadian and European forums. Saddest part is that there have been no replies on the Canadian & eu posts, and the only one on US I've seen was for the user to call tech support and when others said they were also having an issue the mods. Just closed the thread. Obviously people want accurate sleep data, otherwise what's the point? Why can't we exit our times anymore? We had it's not perfect, and don't expect it to be. But what is the point of tracking sleep time and quality it is not going to be accurate? Please put back the ability to edit the times.
After a year of working mostly fine, last night my GW4 watch failed to record any sleep data. I'm an intermittent sleeper and had pretty short cycles, but that's never been a problem in the past. I usually use the sleep function on the watch to see how long each cycle was. Last night it said: "wear your watch at night to track your sleep" even though I was wearing it in the exactly same place on my wrist as always and it was latched on the tightest hole of the band as always
