Add App Exceptions to Do Not Disturb auf Oppo
Do Not Disturb on Oppo phones mutes sound, vibration and pop-up alerts for every app at once. This is a global setting, so it does not know which apps matter to you unless you tell it. Adding an app to the exception list overrides that mute for just that app, while everything else stays silent.
This matters most for messaging apps, work tools or family group chats where missing an alert has real consequences. It also matters for calls, since some apps route voice calls through notifications rather than the phone dialer.
To manage this, open Settings ➔ Sound & vibration ➔ Do Not Disturb ➔ Allowed notifications, then turn the toggle on for each app that should still alert you. Turning a toggle off removes that app from the exception list and mutes it again during Do Not Disturb.
If notifications from an allowed app still do not appear, check that the app itself has notification permissions enabled and that battery optimization is not restricting it in the background. Do Not Disturb exceptions only control whether the mode mutes the app, not whether the app is allowed to send notifications at all.
