If you ever need to take a screenshot on your iOS or Android mobile device (i.e. smartphone or tablet), you can do so easily by pressing and holding the power and Home buttons. For iOS devices like the iPhone, once you press and release the two buttons you should hear the camera shutter and see the screen flash. For Android devices, press and hold the power and Home buttons together until you see the screen flash to take the picture and then release. (If your Android device doesn’t have a Home button, try pressing the Volume Down button and the power button at the same time.) Screenshots get saved to your photo gallery where your other photos are stored. For other devices, including how to take screenshots on Windows and Mac computers, read this article by PCmag.com.
