Learn how to take a screenshot on your Samsung Galaxy S4. First, you have to activate palm motion settings to make it easier to take the screen capture.
Once enabled, you can capture any on-screen information swiping across the screen. In a single motion, press the side of your hand on the screen and swipe form left to right. (as shown in the picture)
Youll see a message appear on the screen that says screenshot saved to Camera shots. With this method, your screenshot will appear in the directory /Pictures/Screenshots. You can also go to your Gallery app to see the screenshots that you have captured.
