How to customize the Side Key on Galaxy phone

All newer Galaxy phones have a Volume key and a Side key. Depending on what phone model you have, the buttons are located on the left or right side.

Here are the default key functions you can use:

• Wake Bixby: Long press the Side key.
• Screen on or off: Short press the side key.
• Launch Camera: Double press the Side key. If you've already set up Bixby Voice, double pressing may open Bixby Assistant Home instead.
• Power on: Long press the Side key while the phone is off.
• Screen capture: Short press the Side and Volume down key simultaneously.
• Power off menu: Press and hold Side Key + Volume down key.

From Settings, tap Advanced features and select Side key, and then tap Side key again.

Here you can select your desired settings.

For Double press, you can choose between:

• Quick launch camera
  
• Open Bixby
• Open app (Tap the Settings icon to select an app.)

For Press and hold, you can choose between:

• Wake up Bixby
• Power off-menu (You can also use Quick settings or Bixby.)
