Notifications have a habit of popping up when it’s the worst time, like when you’re on a call. Do Not Disturb is a setting you can enable that will turn off notifications until you turn it back on again. There is also a way to have it scheduled, which Apple explains in their latest support video.
This tip works on iPhones, iPads and iPod Touches.
If you miss any notifications, you’ll find them in the Notification Center – pull down from the top of your device to see any of them you received while Do Not Disturb was enabled.
