I am samsung lover and mostly I use this brand for phones. It is nice brand but Galaxy S duos not fulfill my expectations and I changed this. I bought this after the month of its launch. It was in range and with good features. But when I used it I face many problems.
This phone has 4GB internal memory and 768MB RAM which is very less and because of this it gave me problems in playing and downloading of games. It has micro SD slot and upro 32Mb memory card afford. But t hang on 8GB. It only affords upto 4GB card.
Battery is not very good. It was down very fast and take much time for charging.
It has 5MP primary camera which is not sufficient. Selfie camera is also not good.
Look wise it is good and nice looking and with perfect size.
According to its price this phone is not worth its money. It has too much hanging problem. I fed up from this and replace it.
There are many phones in market better than this at genuine rates. So do not go for this phone. This will not satisfy your needs.
