Lenovo vibe K4 note is lenovo's new mid budget smartphone. It also has has a fingerprint sensor.
The design is made up of polycarbonate but the battery is un-removable. The back is prone to fingerprints and smudges. The screen can be awake by just putting your finger on the fingerprint sensor just like nexus smartphones.
It sports a 5.5 inch display which fairly big. It also has 3300 mAh battery which I think is average for a phone of this size.
The 13 megapixel back and 5 megapixel front camera is good. It has front-facing speakers which are supported by dolby sound.
The bad thing is that it is sold via amazon india on flash sales which is always very difficult to get.
Overall, it is a decent smartphone which provides performance and camera quality but the bad thing is that it is prone to fingerprints and can only be bought through flash sales.
