This phone Lenovo k3 note is a very good phone for use I have using this phone from 1 year and is running very good but now the screen touch had been damaged. but overall this phone is very good . for playing games its good. sound system is also good and loud and clear powered doubly for better use everyone should opt but now its has been extended to Lenovo k5 note and Lenovo k6 note coming soon . Lenovo mobiles phones good.
