The name suggests that K9 is smart but in reality its opposite. Its better to buy a normal phone atleast it does not hangs. I didnt like karbonn phones anyday. Camera quality is worst its just take pictures like a vga camera . sound quality is that of a chinese phone. If u are thinking of buying this phone plz drop your idea. Buy a decent phone maybe its not a smartphone but that would be better than this.
I would suggest you all not to waste money on these types of phones. Keep checking reviews and then decide to buy a phone.
