What does the status bar icon indicate when Do Not Disturb is enabled?

When Do Not Disturb is enabled on a device, the status bar icon signifies that the feature is active. This means that calls and alerts, including notifications from apps, will be silenced while the feature is on. The main purpose of Do Not Disturb is to help users focus or get uninterrupted rest by temporarily limiting interruptions.

In contrast, the other options relate to specific features that do not necessarily indicate a Do Not Disturb status. An alarm being set, a sleep timer being used, or bedtime alarms configured serve different purposes and do not denote the silencing of notifications across the device. Understanding this function of the Do Not Disturb feature is essential for users to manage their device notifications effectively.
