I thought Samsung Galaxy Grand is a good mobile to buy but it's not all my money goes in dustbin. Samsung Galaxy Grand has- 1.2 GHz dual core processor, 1GB ram, 8GB internal storage which can be expandable to 64GB, 5 inch screen with resolution of 480x800= 187 pixels per inch, 8mp rear and 2mp front camera with flash, Android 4.1 and 2100 major battery. I like it's specifications and I buy it but after using it the mobile is always hangs and lags, battery life is also disappointing and it's poor display. I thought Samsung make good quality products but I can say that's not true after using this mobile. Not a value for money products. New name= Samsung Galaxy trash. I will not recommend this mobile to anyone to buy.
