Bixby is working with voice have to hold Bixby button
Or just activate the Hi Bixby command, it works even with the screen off so it's always listening. I prefer to press the button as I don't like to activate any AI with the "Hi ..." Command.
I still have to unlock my device for bixby to do anything, y'all seeing that too? She wake up but need to draw my pattern or finger print for her to be allowed to do anything.
