Whether you’re a designer trying to get a mobile layout pixel-perfect, a frustrated customer needing to document some strange behavior for the folks at the Genius Bar, or a wordsmith wanting to memorialize your latest Words With Friends achievement, you’re going to need a screenshot.

Luckily, every portable iOS device has a super-simple way to capture whatever’s happening on your screen.
Simply push the sleep/wake and Home buttons simultaneously, and you should see the screen flash, accompanied by the familiar camera snap sound—provided your device has a built-in speaker.
