To turn off Do Not Disturb on an iPhone, open the Control Center by swiping down from the top-right corner of the screen (on iPhone X and later) or swiping up from the bottom (on earlier models). Then tap the Do Not Disturb icon, which looks like a crescent moon, to turn it off. This will stop the mode and allow notifications and calls to come through again. You can also turn it off by going to Settings > Focus > Do Not Disturb and disabling any schedules or the mode itself. Additionally, you can ask Siri to turn off Do Not Disturb for hands-free control.
Summary of steps:
- Open Control Center (swipe down from top-right or swipe up from bottom)
- Tap the crescent moon icon to turn off Do Not Disturb
- Or go to Settings > Focus > Do Not Disturb to disable it or manage schedules
- Use Siri by saying "Turn off Do Not Disturb" for hands-free operation
This feature is permanent on iOS, but once turned off, notifications will come through normally again.
