One popular feature of the volume up/down button on your phone is the camera function. When using the camera or recording video on your phone, you can start the recording process by using the volume up/down button instead of tapping the shutter button on the screen.
Keep in mind that to use this feature, you may need to go to the camera app settings to enable the option to take photos using the volume up/down button.

When you use your phone, if you want to take a screenshot immediately, just press and hold the power button and the volume down button simultaneously. The screen will be captured quickly without needing to access the control center.
6. Flip Book Pages
When you read e-books on your phone, the volume up/down button can also help you flip the book pages automatically. You don’t need to tap the screen to turn pages. Note that the feature to flip pages using the volume up/down button may vary depending on your reading app and phone model.
