I just gave this mobile to my bro as it was not working properly. Its all features are dump. Its sound quality is worst. My mobile was just getting hang everytime, everyday when I used it more.My mobile was not that much slim and it was not atttractive. It does not give battery backup also. I was just using this mobile only 5 hrs in a day continuously. Ya I can say tht it is quite loww weight. And it is so expensive according to given features. So its my duty to aware you all about this what I am experiencing using this mobile.
