How to disable Do Not Disturb on iPhone 15

Hello,

Start here:

Use Do Not Disturb on your iPhone, iPad, and iPod touch

An easy way to turn it off and on is to go to the Control Center (swipe down from the upper right corner) and press the Focus button.

Good luck.

I’m having this issue too. There are no Focus modes turned on and Do Not Disturb shows as turned off, yet my texts show it is turned on and my phone doesn’t ring. I’ve missed customer calls because of this. I did the most recent update and restarted the phone with no change to this issue.
