Lenovo k4 note is a very good phone I am very happy with this phone, its easy to carry and the features which I am getting in the price is very good, its very stylish even I can show off this phone to anybody, music sound is very good, because of dual speeker its sounds loud and clear, phone size and slimness is very good, with Rs 11999 its gives 3 GB rame that is very good, but games are sometimes stucking for a second, and the major concern is the battery which is draining little early.if it would have been no problem with the battery back up than this would have been the best phone in this budget.
