I m using this phone since one year for my opinion
Lenovo vibe k4 note phone are very good phone
In this budget.
It has many new features like vr mode,
Fingerprint lock, and its also 4g supportable with
13 mp rear camera and 5 mp front camera.
And also 5.5 inch display with Corning Gorilla Glass 3 protection.
And amazing 3gb Ram with 16 gb internal storage.
Its very value for money phone.
