How to Screenshot on Mobile

Few days ago, I need the screenshot of my whatsapp message for sharing it on my facebook profile for giving value to my whatsapp message. But problem was that I did not have the knowledge of screenshot on mobile. I checked lots of content which is showing down volume + power button. But, it does not apply on my phone. But I am lucky I find great shortcut that is best for my mobile and hope also on your mobile phone.

Just see the screen which you want to shot and then for screenshot on mobile, just press home button+ power button together and your screenshot will save in gallery's screenshot file.
