Galaxy s duos is my first mobile which I have used this mobile is absolutely worst. Even Samsung galaxy y is better than this one.
I recommend not to buy this phone.Go to buy any other brands at this price they will give great features. I have purchased this mobile for 10000 in the year 2013 december. there are many dis-advantages from using this mobile for example it is very slow, hanging, apps not working, fast battery discharge.
I struggled very much after buying this mobile and finally I sold with in 3 months for 4000. now the price of the new mobile is 6000 we are finding very new models in the market.
