“Do Not Disturb” is a very useful feature in iOS, which silences calls and alerts when iPhone is locked. If you are in a meeting or don't want to be distracted by incoming calls or random notifications, you can enable DND to remain at peace.
But, there is one problem, and you know that very well, don't you? When DND is enabled, you will miss out important calls or alerts. That's one the main reasons why I'm a bit hesitant about enabling this feature on my iPhone.
Fortunately, Apple has solved this problem in iOS 10 by allowing you to receive sounds and vibrations from specific contacts even when Do Not Disturb is enabled on your iPhone or iPad. So, now you will not miss out important calls or alerts from your special contacts.
“There is an Emergency Bypass option dedicated to each contact in Contacts app on iOS 10. When enabled, it permits audio, and vibratory alerts from that particular contact even when Do Not Disturb is on.”
How to Enable/Disable Emergency Bypass for Specific Contacts in iOS 10 on iPhone or iPad
Step #1. Launch Contacts app on your iPhone.
Step #2. Next up, you have to select a contact.
Step #3. Tap on the Edit from the top right corner.
Step #4. Up next, you need to tap on the Ringtone or Text Tone section on the contact card.
If you want to receive ringtone sound even during DND is on tap on Ringtone. Likewise, if you wish to receive sound of notifications, tap on Text Tone. You can enable both the options depending on your need.
Step #5. Finally, toggle the switch next to Emergency Bypass.
That's it! From now onwards, you will receive audio and vibratory alerts from this contact. If you ever want to disable this feature, just follow the steps as mentioned earlier and turn off the switch in the end.
Apple should have added this feature much earlier. However, it's better late than never.
