What is Blocking Mode and how do I use it on my Samsung Galaxy S III mini?

Blocking mode lets you block incoming calls and turn off notifications, alarms, and the LED indicator.

Blocking Mode

To turn on the Blocking mode feature, from the Home screen, touch Menu > Settings > My device > Blocking mode. Touch the slider off to turn Blocking mode on. Mark the checkboxes next to the features you would like to use. Choose Block incoming calls, Turn off notifications, Turn off alarm and timer, or Turn off LED indicator.

Set the time you would like the Blocking mode to be active for, or mark the Always checkbox to keep it on constantly. To receive notifications from specific contacts, touch Allowed contacts, and then select Custom to add contacts to the Allowed contact list.
