Hlo friends I am telling about Karbonn K9 Kavach 4G.i buy this useless phone last two months. shopkeeper tell me about this phone. he says this phone is totaly good and and some other features its looks are very foolish. its camera is only 5 mega pixels which don’t pick clearly selfies and its main problem is over heating and its most worthless problem is hanging which make me angry. so I request to my all friends please please dont buy this phone.
