Cannot Run Mobile Software on samsung Duos

I recently got a Samsung DUOS but I don't know the version of the phone. Tried hard in searching for the model number on Internet.
It has many softwares like TalkingTom, AngryBirds, FruitNinja, etc.
And, I want to download some more softwares such as games, apps, etc.
I copied some music and video files and they worked. So, there is some problem with the system.
It shows that its platform is : Mex
So, it means that I want to download softwares for Mex Platform.
If yes, please tell me the site form which I can download these kinds of softwares.
If no, then what is this problem and how to solve it?
If you also want Image please reply.


Please solve this awful problem for me as soon as possible.

Hack.. are you even sure you have real Samsung, open its back cover and tell us what version is written on back which you see after removing battery.

Can you post its photo here ?

I'm not sure it its real Samsung. Its very hard to open the cover. It tells that it is Samsung DUOS.

Here's the photo :

Its in OFF state or its ON while you took that picture, what I see on top of screen , are they permanent icons there ie. touch panel kind of or they are their because phone is on ?

This one looks to be Samsung C3312 Duos and if thats true then its a Java phone and you can only run java apps on it. Just remove back cover and see its model ..
