The iPhone emits sounds for various actions or notifications. These sounds come from the device's speaker and can sometimes be unwanted or annoying, depending on the situation.
That's why you might want to turn off the sound on your iPhone X. If you want to deactivate the sound on your iPhone X or mute the device, you can do this simply by pressing the following hardware button:
On the right side of the housing you will find a switch at the top. With this you can mute the iPhone X so that no sound is output anymore. To set the iPhone to "Silent", set the switch so that the orange background is visible.
You have now successfully muted iPhone X.
