My friend have this phone and I used it.Lenovo vibe k4 note isnt a camera phone, it have only 13Mp rear camera with phase detection, auto focus, dual led flash, which is not impressive, camera performance is good but not satisfied me.display is ips LCD capacitive touch screen, 16M Colors, 5.5inch display with Resolution 1080×1920Pixels which is impressive.colors look washed and low contrast, there are many other phone which is giving better Display, camera, battery and performance in this price.Performance is very good and Multitasking also good.but its UI disappointing me.i am not satisfied with its front camera, it is blue.while I am changing this phone and along with that if I am using this then within certain period of time it gets heated up quickly.battery drains out very soon if you are using the internet.although it has 3gb of ram but it generally hangs a lot.it haveOcta core 1.3ghz processer and internal memory 16 GB expandable up to 128 GB, Android version 5.1 with 3300 mAh battery non removable.overall I dont like it.
