Lenovo k3 note I have been using for last 1 year . and it is very good phone . sound qualiti is best becouse of having dolby. Some time it heats but now a days every mobile gets heat so it is not a problem .
Camera is also good rear camera 13 mp and front camera 5mp. It is very good for silfi lover.
16gb storage is also good and 2gb ram.u can play big games easily.
