I'm using a nightly build of CM13. I recently noticed this round icon with a horizontal line in its middle. The icon is located in the right side of the notification bar.


What does that icon depict?

"Do Not Disturb" was turned on, you can swipe down the status bar and toggle it on/off. Settings for it would be for a specific duration, Until you turn this off. You can opt for Total silence, Alarms only, or Priority only.
