Before proceeding further, make sure that your iPhone is running the latest iOS 14 version of the operating system.
Step 1: On your iPhone, open the Settings app.
Step 2: Swipe down and tap on the “Camera” option.
Step 3: Now, toggle on the “Use Volume Up for Burst” option.
That’s it. Now, whenever you open the Camera app on your iPhone, you can quickly grab photos in burst mode by pressing the volume up button on your device instead of tapping and dragging the on-screen shutter button.
