>> Is the software up to date? Have you tried a reset of the unit?
Thanks for the answer. For me, software reset did not help. It happens only at night or in the morning. Looks like a software bug, but I don't understand what cause it - datetime, darkness or motion.
Also, the watch turn display off immediately when I put it from a hand, maybe its connected somehow. I also have "Do not disturb" enabled on the phone, but not on the watch, maybe its somehow connected. Phone is Samsung Galaxy S8.
Software is up to date, I checked for updates, it shows that the version is the latest.
No, timeout works fine, after 15s display is switching to a low brightness.
Its hard to tell when it exactly switching off because at night I am sleeping (and when I wake up, its off), but its definetely more then after 15s.
It never happens for me at the day time, so probably its somehow connected with ambient light brigtness or less motion (maybe watch algorithm decide that the watch is not on the hand?)
