I liked the phone as it gives many amazing features in a price range of 12000 making it the best smartphone under 12000. The new feature which is new than its predecessor k3 note one of the best phone under 10000 is the fingerprint sensor which is hard to get under 15000 even though coolpad note3 has this feature in only 8999. K4 note has a powerful battery of 3300 mAh which is impressive. The best think I liked is that it is compitable with virtual reality which will take you to a new world. At the end I want to say that I liked the phone and suggest it to the buyers who want the best phone under 12000.
