Hi I purchase the samsung galaxy duos I8262 in 2012. Actually my wife gifted me on my Birthday. I would like to say the performance is good till now. But it has hanging problem. It may be to heavy data on the internal memory of the phone. My 5 year son downloaded new games on the same. Did many clicks of the camera. I inserted 16 GB memory card in it.
Battery Life is Good after 4 years. There is low backup compare than before but after 4 years its good.
Overall performance is also good.
Its rough & Tough. It falls many times.
Minus Point is only The Hanging Problem.
