The Do Not Disturb (DND) mode is a setting that silences notifications, calls, and alerts on your device to help you avoid interruptions.
For your reference, here are more details about the DND mode:
1. After the Do Not Disturb mode is turned on, incoming calls and application notifications will not be received. However, system prompts, such as alarms, will still be reminded;
2. When you set the Do Not Disturb mode synchronization on the APP, the device and the mobile phone remain connected, and the Do Not Disturb state of the device will be synchronized with the Do Not Disturb state of the mobile phone in both directions, that is, one device is turned on Do Not Disturb, and the other device is also synchronized to turn on Do Not Disturb.
Note:
The Do Not Disturb synchronization function is only supported on phones of Android 11.0 and above.
