While it’s possible to disable Bixby entirely, it may be simpler to assign the function permission to access only certain apps so that you can take advantage of the features on offer.  Here’s how: 1. Head to the Bixby home page by holding down the side key (or double-tapping if you’ve already changed the feature). 2. Tap on the three vertical dots on the right-hand side of the screen. 3. Hit “Settings,” then select “Bixby Key.” 4. Choose the “Single Press” option from the available functions by tapping the toggle. 5. Select “Open App” to choose a single app from the list of installed apps on your phone. You can also tap “Run a Quick Command” to run a quick Bixby command when pressed.
