This is good phone from samsung. They are providing a high class technology inside this phone, but price is little high. They are providing 64GB, 128GB & 256GB inbuilt memory and 6GB Ram which is more enough for a smart phone because we can use external storage devices for expanding the memory. Its battery capacity is 3300MAH that is vey satisfactory in our busy life. I feel very cool with this phone because its size is affordable and its curved full screen so cute. I like it very much.
