Redmi note 4 is the beast . I m using this phone since one month and in this one month period I have not seen any kind of issues .It has best design full metal body and also so slim . Talking about the performence it is so good so fast there is no heating issues , no hanging problem .Best phone of the year in india . You can not get another best phone in this price range. Goo camera for day light but for low light its not that much good. Overall this phone is the best.
