By changing the settings of Android’s “Do not disturb” mode, you can limit receiving calls to your favorite contacts only.
Android smartphones have a “Do not disturb” function which mutes the ringer and vibrator. It is activated from the quick action area (displayed at the top of the screen with a simple swipe of a finger) or by lowering the volume to the maximum or by launching a search in the parameters menu with the “Do not disturb” keywords (also called “Silence settings” or “Alert slider” on some devices).
But you may need to be available for some people. Here’s how to configure this mode so that your favorite contacts can always ring your smartphone’s ringtone.
1 – Define your favorite contacts
In Android contacts, accessible directly by an icon or through the dedicated menu, find the one that interests you, then press the star at the top of the screen. He is then considered a favorite contact.

2 – Change the Do not disturb mode
Open menu Do not disturb through the quick action area (see image below). If it is absent from this zone, the operation can also be carried out by going to the section His Android settings or by searching by keywords in general settings. If you can’t find anything, try a search with Alert slider Where Silence settings.

In Android 7, tap Priority only, then on Calls. Choose Favorite contacts only in the list. You can also turn off the switches Reminders and Events.

Under Android 8 or 6, in Do not disturb Where Silence settings, press directly on Calls / favorite contacts only.
After these changes, only your favorite contacts will be able to call you when you have activated the mode. Do not disturb.
