I recently used this phone from Samsung the model was galaxy S duos 2.The first thing that I didn't like was the size as well as the shape of the phone.The camera quality was also not at all good.Also when I installed High graphics games the phone lagged and it was a very bad experience with this phone.Also the battery life is also not that great at all.It does not work for one entire day also.
So I would not recommend anyone to use this phone at all an don't even try buy this phone at all as you will easily get a new phone with better specification then this so don't think of buying this phone
