Samsung's virtual assistant introduced with the Galaxy S8 smartphones in 2017. Along with a dedicated button residing below the volume buttons, Bixby was designed to command the device by voice and provide an alternative to tapping the screen. A Bixby "Home" app provides news and information replacing Flipboard, which was in the S7 devices.
No More Bixby Button
The dedicated Bixby button was eliminated on the Galaxy S20 and Note 10, although the power button could be long pressed to activate the app.
An always-available option in the camera app, Bixby Vision is able to identify images and provide information about them. It can also translate text. Not just for phones and tablets, Bixby and Bixby Vision are expected in other Samsung products. See Viv
