Screen capture for Android 4.1.2

[desktopuser]

Hello, i have one more question, i.e., is their any screen caturing utility for Samsung Galaxy Core Duous I8262.
So far i searched and some i got from Google play but it fails to take any, some errors pop's up.
Since I8262 is not rooted, rooted application doesn't run, so i got one screenshot ultimate and other but it didn't work.
Any suggestion from android users.

I found the answer and that was, press Power button and the Home button simultaneously, and it gets saved in phone memory.
Don't bother please,its fixed.
