You may also schedule your Do Not Disturb feature to turn on and off at set times, for instance 10pm to 7am. You can also pick the days to automatically go on and off.
I have an android. It's in Settings > Do Not Disturb. In Do Not Disturb you can Allow exceptions to recieve calls from certain contacts or all contacts.
I forget that I even have mine set, but it sure is nice not to be bothered while sleeping. In an emergency, if someone repeats a call within 15 minutes the call will come through. This is probably standard on most smart phones. |
