Screen Captures in Feature Phones?

[Osthe]

When I was reading a review about Samsung Champ GT-C3303 (my current mobile) in GSMArena, I saw the screenshots of Homepage, Contacts List, Menu screen, etc. Immediately, I searched for some other feature phones and read the reviews and to my surprise those reviews also had the screenshots of the respective mobiles.

Now, My Question is "Is it possible to take screenshots of feature phones? If yes, then how? Can anyone guide me?"

I am interested in writing a review of my 1-year old Samsung Champ GT-C3303 (which i am going sell and buy a high-end smartphone before Q2 2012) here at "Reviews" Section. I hope the screenshots will make the review more professional.
