Samsung Galaxy S Duos is the worst phone l have ever seen and used. From the very day l bought it network complaints, slowness, hanging started to occur. Internet is very slow in this. Eventhough it is a dual SIM phone both SIM dont work properly. The battery also drains very fast.
The only thing l can say good about the phone is its Camera. Of course it gives the clarity and perfection of a 5mp camera.
