Here are six hidden phone functions many may not know: Mute Incoming Calls If an unexpected call comes in, “press the volume down button” to mute the ringtone without disconnecting the call. This works for alarms or notifications as well.
Turn Off the Flashlight Instead of unlocking your phone to turn off the flashlight, press the volume down button twice.
Keep in mind that “not all phones have this feature.” Adjust Phone Volume To quickly adjust your ringer volume, press the volume up or down button directly after unlocking the screen, saving time.
Camera Shortcut You can use the volume button to take photos or record videos instead of tapping the screen.
