Why do you want to disable Bixby?
One of the biggest annoyances of the Bixby button is its placement; it's located on the right side below the volume keys and almost directly opposite the power button. On larger phones like the Galaxy S9+ and Note 8, this often leads to accidental presses and inadvertently triggering Bixby, especially when double-tapping the power button to open the camera.
The Bixby button isn't mapped for any other action; Samsung wants you to use this button for Bixby and nothing else. Therefore, many people will likely opt to just forget about this button and move on.
How to Disable Bixby Voice
Bixby is divided into two distinct types: Bixby Voice and Bixby Home. Bixby Voice allows you to perform tasks by long-pressing the Bixby button, akin to a walkie-talkie. While this feature can be useful, it can also be bothersome when not functioning properly, hence you may want to turn it off before disabling Bixby Home (accessed by pressing the Bixby button).
Step 1: On the Samsung home screen, swipe right until you reach Bixby Home.
Additionally, you press the Bixby button on the left side of the phone, just below the volume button.
Step 2: At the top menu bar, tap on the three vertical dots icon
Step 3: Select Settings
Step 4: Uncheck Bixby Voice.
Bixby Voice will no longer bother you when accidentally holding down the Bixby button. Next, we need to prevent the Bixby button from accessing Bixby Home.
How to Disable the Bixby Button
Since Bixby Voice has been disabled, you now need to disable Bixby Home from the pop-up window when accidentally pressing the side button.
Step 1: Press the Bixby button on the left side of the phone, just below the volume button.
Step 2: At the top menu bar, tap on the Settings button (resembling three saw teeth).
Step 3: Uncheck Bixby Key.
Now, when you press the Bixby button, it won't open Bixby Home.
How to Disable Bixby Home on the Home Screen
The final step to fully disable Bixby is to turn off Bixby Home access from the default home screen.
Step 1: On the home screen, long-press an empty space until the menu appears.
Step 2: Swipe right to access the left-side home panel
Step 3: Turn off Bixby Home
Now, both the Bixby button and Bixby Home are inactive, allowing you to use your phone without accidentally accessing Bixby.
However, if you want to re-enable Bixby, simply follow the reverse steps above, conveniently enabling Bixby Home from the launcher, then toggling the Bixby button within the menu. Samsung S8 users can refer to how to disable Hello Bixby on Samsung S8 here.
