I have recently got a Galaxy watch6 classic, LTE version. I have been using Samsung smart watches to track my sleep and other health metrics since years. I am very much concerned this time that the sleep measured by the watch6 classic seems to be very inaccurate. The first day I used it, it didn't record the sleep at all. Since the second day it started recording sleep but it seems to detect the sleep hours later than when I fall asleep. It also doesn't record any of the deep sleep stage eg. since 5th of August, when the watch came it never picked up a single period of deep sleep. There also seems to be a new rule of measuring sleep statistically rather than using the sensor. I often noticed when I am at work during a night shift, at 12am to 1am in the mid night it starts recording sleep, and automatically goes to sleep mode even though I used to be very much physically active during that time. Another new rule I've noticed is that it doesn't record sleep for a second time in one day. During my off day yesterday I slept for at least 10 hours. I went to bed at 9pm and woke up approximately at 7am inext day morning. I woke up in the middle at 4:13am to use the bathroom. When I checked the watch6 classic it only showed me 4h 9m of sleep, starting from 12:05am to 4:14am, till when I used the bathroom. After using ot since two weeks, It is clear to me now that my Watch6 misses the majority of the sleep to record and will record sleep only once a day depending on some statistical rule rather than using the sensor to detect the sleep pattern match. I had a Watch4 classic before this and the sleep measurement has always been very very accurate on that watch. The Watch6 classic has got numerous bugs and issues eg. another of which is not receiving any phone notifications in the watch for which I had to reset the watch many many times over the last two weeks ( I explained it in detatils in a separeate thread ). I cant beleive, I have spent my £413 for such a good looking rubbish item. I am extremely, deeply disappointed by this new watch. My Watch4 classic was way better than this - at least in measuring the health metrics.
