Assuming you have a compatible device that runs the Samsung Android Pie / One Touch UI, you need to get a new update to bring the most requested feature to your phone.
There are some warnings about the function as it is The rimDan Seifert on Twitter: You cannot delete the Bixby button to start another helper, such as Google Assistant or Cortana, even if you have installed these applications.

Users cannot turn off the button completely or remove Bixby. The best thing we can do is set up a single press to launch the chosen application, while the dual press opens Bixby. Regardless of the settings you use, Bixby always starts and presses the Bixby button.
