In iOS 12, Do Not Disturb has several useful 3D Touch shortcuts. Simply deep press on the DND icon in the Control Center to view them. You have the option to quickly set DND for one hour, until this evening, or until you leave your current location, which is perfect for the movie theater. Also, DND has access to your Calendar, so if you are in a scheduled event you will also have an option to turn on DND until the event is over. The schedule button will take you to Settings where you can make a custom schedule.
Do Not Disturb
Blocking calls on the iPhone can increase privacy, reduce spam and offer peace and quiet when it's most needed. The iPhone has several features designed to help block undesired calls. One way to reduce annoyances is with the Do Not Disturb feature. Blocking an individual number can be convenient, but sometimes it's not enough. There's an easy way to block all calls that are not listed in your iPhone Contacts.
Most iPhone users should know that the Do Not Disturb mode is the easiest way to stop their phone from ringing, chirping and vibrating while they are at the movies, in a meeting or just trying to get a good night's sleep. What many may not know, however, is that you can customize the Do Not Disturb settings to allow certain calls and notifications through, and you can schedule it to automatically turn on at specific times. If you want to allow possible emergency calls from family come through, you can do that.
