It is really easy and there is few methods how to do it. I`ll show you two, most common ways to create screenshots on Android. Of course, both methods are built in to Android 4.0 and later versions.
I have two Android devices. Hauwei MediaTab tablet and Sony Xperia phone. First method is working with my Sony Xperia.
All you have to do is to hold power button on the side of the phone for about second. On power menu screenshot option will be shown (Slide 1.).
Slides will saved in Pictures folder.
Second method is working on my MediaPad and on many other devices. It is similar to first, although it is a little impractical. Again press power button on right side of device and in same time down side of volume button (Slide 2).
