How to take screen shot on your Android Device

     If you're running Ice Cream Sandwich (4.0) and above just press the Volume Down and Power buttons at the same time, hold them for a second, and your phone will take a screenshot.

     If you're running android 2.3 and below (Android 2.3 and below doesn't have screenshotting built-in; However some devices like many Samsung phones do have these features, but you can install it) you can press the Home and Power buttons at the same time to take a screenshot.
