|Hardware Buttons Overview / Using the DND/Hold Button|
You can set a DND duration to publish your non-availability. You can do it by pressing the DND button in an idle state.
To set your DND duration, perform the following tasks:
A panel slides up from the bottom of the screen. The options (5, 10, 15, 30) min, 1 hour, and infinity are displayed. If you do not select an option, the infinity option is set.
The DND duration is set, and the option slides out of the view.
The infinite icon changes to I'm Back.
