We all know redmi note 4 is last year phone which was sold more than 50 lakh piece . With the release of note 5 in same price its value is decreased . Its Powered by Snapdragon 625 which is also used in Note 5 . So performance might be equivalent but Note 5 is introduced with 18: 9 display which makes a variation. So My friend Sold his note 4 to me in 6500( 3GB Variant) . Its all like new so I got almost a good deal. Performance is very good .
So Its a all rounder phone battery performance is also much better than my samsung . So if you are thinking to buy a new phone in 7K I
might suggest you to search for a old Redmi note 4 Its is more valuable deal Otherwise go for note 5
Thats all my opinion about redmi note 4 . Let me know your in comment.
