I am still in the early phases of figuring this out, but I’m hoping maybe this issue will ring a bell for anyone using a Garmin Vivoactive 3 with Sleep as Android. It seems that sometime during the night, the Vivoactive 3 restarts, interrupting sleep tracking. The only way to reconnect it is by manually starting the Sleep app on the Garmin device. Since I’m usually sleeping during this time, though, I’m unaware of this connectivity issue. I’m only guessing that the watch is restarting because I’ve once or twice seen it happen while I’m awake just before bed. Most times it happens after midnight. The triangle appears on the face of the watch as it reboots. My first thought is that this is an issue on Garmin’s end. I’ve tried disabling all automatic updates of the Garmin device to try and avoid reboots, but that was fruitless. The “crash” seems to occur most often during sleep tracking. I suppose it’s possible there’s a bluetooth connection error as well, but that seems unlikely as my phone and watch stay connected throughout the day while I move about the house.
Again, I’m really just curious if this happens to others, and if anyone’s found a solution either here or in Garmin’s support forums. Thanks in advance for any clues!
But apparently this is not the case.
