Since last one and a half year I have been using samsung GT s7562 smartphone which actually not a smart phone. I had purchased it for rupees 10, 000 but is not worth it.
Its internal memory is around 2 gigabytes and RAM is only 645 megabytes! Yes only 645 mb. That why its always keeps on hang if I start an application or game.
Also I have changed my phones battery twice from when I purchased it. Because it was blown up like a balloon.
I am suggesting people not to buy such samsung smartphones, because its fully waste of money.
