How to take a screenshot with the Samsung Galaxy S2

Presuming you have the latest supported version of Android on your Samsung Galaxy S2 (4.1.2), here are the steps for taking a screenshot:

1. Hold down on the POWER BUTTON and the HOME BUTTON simultaneously, but keep them held for more than a second.
   
2. Wait until you hear a sound or see an animation on the screen. You will then receive a notification that a screenshot has been taken in the notification bar.

The screenshot will be saved in your "screenshots" folder, which can be accessed quickly via the gallery.
That's all there is to it folks
