What is a one-sentence summary of the following article?
A screen capture or screen shot is a photo of the entire phone screen. It is often used to show people maps, texts and other real-time information.  You need only press it once, rather than holding it down. The outside border of the screen will also flash when the photo is taken. It will be saved in a screen shot folder alongside other types of photos. You can text or email the photo by sharing it from this folder.

Summary:
Find the screen that you want to capture. Press and hold the Back button on the bottom right of your phone. Press the Home button simultaneously. Listen for a shutter sound indicating there was a screen capture. Access your screen shot in the Gallery app.
