I've been using 945 for some time. I have found several problems.
1. In judging the sleep time, I only sleep deeply for ten minutes or tens of minutes every day, but light sleep for several hours. I feel that this is not right. And often when I get up in the morning, deep sleep shows one or two hours, and later only display a few minutes.
2. There are also some problems in my swimming style judgment. Basically, I will recognize my freestyle as breaststroke. I swimed about 1,000 meters.
3. Another question is why my 945 always turns into 'Do not disturb' automatically and need to be turned off manually? Where is this set?
