Run a Quick Command in Bixby

Rather than assign the second action of the Bixby key to a specific app, you can also choose to Run a quick command.

A quick command is a set of actions that you choose to happen when you press the Bixby key one or two times. For example, if you want to set your phone up to automatically reduce distractions while you're driving, you can set the quick command option to turn on Do Not Disturb, turn off the Wi-Fi, and turn off the Always on Display.

To do this, instead of selecting Open app on the Use single (or double) press page, select Run quick command on the page that opens when you select either a single- or double-press. Follow the on-screen instructions to set up the quick command routine that you want to use.
