My Galaxy Watch 4 told me it had an update a couple of days ago and installed. After the update Bixby was installed and active on my watch, and would buzz at me like every 5 seconds prompting me to tell it what I wanted. It was really annoying. I changed to the google assistant as I couldn't see a way to turn off assistance and just have a watch. My watch after a few hours went black, and would not respond to the buttons at all.
