I bought the mentioned phone as it looked nice and I was looking for a phone which was not bulky and had all the features I was looking for.as I started to get the hang of it I realised it was not so user friendly.It behaves in a manner which can irritate you so much.
Even if you are near a wifi, it will not connect to an internet easily .Whatsapp is another story altogether.You will never be able to send a msg when you want.It will freeze in the middle of something and you wont even be able to restart it. To sum up it is by far the worst smart phone one can buy. Please do not get carried away by the advertisements. Wonder why samsung came up with a phone like this .
