How to turn off do not disturb

Hi Yongfromga,

Thanks for reaching out to Apple Support Communities.

It sounds like you would like to turn off Do Not Disturb on your device.

We’re happy to assist.

To turn off Do Not Disturb, open the Control Center and then tap on the Focus button to turn it off. You can learn more about that here: Access Control Center on your iPhone

If you would like to delete any planned settings so Do Not Disturb doesn't turn on anymore, you can do that following the steps under "Change your Do Not Disturb settings" found here: Use Do Not Disturb with Focus on your iPhone or iPad - Apple Support

The reason why we’re recommending the steps above is because they directly address the issue you initially posted about: you'd like to turn off Do Not Disturb.

Please do not hesitate to reach back out to us if you have questions or need any additional support.
