If you need to take a screenshot of your new BlackBerry 10 smartphone, all you have to do is press the Volume Up key and the Volume Down key at the same time. A screenshot is taken and saved to your phone memory. Easy pie.
Don’t forget: Press the Volume Up key and the Volume Down key at the same time.
PS: If you own an older BlackBerry smartphone, e.g. a Curve, Torch or Bold, you need to download apps like Screen Shot FREE, Capture It or Screen Muncher from BlackBerry AppWorld to take screenshots on your device.
