What the half-moon icon means on your iPhone, and how to turn it off

This icon means that your iPhone’s Do Not Disturb feature is enabled.

When Do Not Disturb is turned on, all of your phone calls will be sent straight to voicemail. While you’ll still receive texts, you won’t see an alert for any new ones that come in while the feature is enabled.

In addition, none of the apps which you've allowed to send notifications will be able to do so.

If you want to disable the Do Not Disturb option, doing so is pretty easy and can be done in one of two ways.

How to turn off Do Not Disturb on your iPhone

Swipe up from the bottom of your iPhone's home screen (or from the upper right corner on the iPhone X and later) and locate the half-moon icon in the Control Center.

This small box should be dark; if it's illuminated white, Do Not Disturb is enabled and you'll need to disable it. To do so, just tap on the icon until it turns gray and you're good to go.

How to unmute a conversation in Messages on your iPhone
