If we want to receive calls while the "Do Not Disturb" mode is active, we have to add them to the exception: On the Oppo smartphone we have the possibility to allow calls from all, from contacts or from selected contacts.
Note: On the Oppo smartphone, a single contact can be marked as a VIP, and this contact is automatically excluded from the "Do Not Disturb" mode.
- Open the Settings
- Tap on Do not Disturb
- Tap on Allow calls from
- Choose between From anyone, From contacts only, Starred contacts only and No one
