Yes, the Do Not Disturb button on the iPhone blocks calls when it is activated. When you enable Do Not Disturb mode, it silences all incoming calls and notifications, preventing them from making sounds or vibrating your device. This feature proves useful when you want uninterrupted moments, like during meetings, presentations, or when you're sleeping.
To activate Do Not Disturb mode on an iPhone, you can follow these steps:
1. Open the Control Center: Swipe down from the top-right corner on iPhone models with Face ID, or swipe up from the bottom on iPhone models with a home button.
2. Locate the crescent moon icon: The Do Not Disturb button is represented by a crescent moon symbol. Tap it to toggle Do Not Disturb mode on or off.
3. Customize Do Not Disturb settings: For further control, you can head to the Settings app and access the Do Not Disturb settings menu. Here, you can schedule specific times for Do Not Disturb to activate automatically, allow calls from specific contacts, or configure repeated calls to bypass the feature.
By activating Do Not Disturb mode, you can ensure that calls and notifications do not disturb you during critical or designated times.
