Lenovo k4 note is a successor of lenovo k3 note which also got much hype. but what was lagging in k3 note was taken care in this k4 note.
Specially when it comes to ram ( 3gb instead of 2gm) , camera clarity in terms of low light, dual firing dolby speaker at front, , metal frame , finger sensor, nfc.the most attractive notice worthy thing which I found on this handset is its speaker quality it is just creating woo.
The finger sensor is just able to recognize 2 fingers that also in 360 degree , but I am shocked that lenovo is not providing the headsets. Overall the battery durability is also good which gives somewhat useful calling time.
