How on earth is this a fix, this is just a workaround not a fix. Surely someone at Samsung knows what this blue dot is?
I also see blue dot in the middle of the screen.
Yep, had it twice after removing last messages. Reboot and its gone.
Just power down the watch, restart it again and it's gone.
I don't know why it's there in the first place.
I saw mine do it today. It has never done that.
In the Galaxy wearables app on the PHONE, go to accessibility and under "functions in use" turn off the voice assistant. That's it. That's all there is to it.
