My Ultra 2 did this a few days ago, startling me. I didn’t see any speculation in that thread as to why it happened. Any HN theories?

  Are you running 10.4?

    It happened prior to my 10.4 update. I don’t recall doing anything to trigger it. It just happened one day. A hard reboot stopped it.

      10.4 has been out for about a month. You should check your watch is able to update when you’re charging it. Scary bug.

  Capacitive touchscreens are tricky. You want them to be sensitive enough to work quickly when touched, and sometimes through gloves or when wet. But if they're too sensitive, or don't recalibrate well to dynamic conditions, you start to get false touches. Another root cause is usually a noisy ground from a power supply, but I would hazard a guess that's not a problem for a standalone watch.
