Do not disturb...iPhone?

[Stainless]

Swipe the phone from bottom to top which will bring up the following screen. Then click the moon.

When the phone is locked, you should be able to press the center button to show the clock.
At the bottom of the screen you be able to "thumb up" a menu....Swipe your thumb going up. Across the top of the menu bar, you should see the crescent moon.
It will probably be lit up. Just click it and it will turn off..

Thank you both! I forgot about swiping up.
