This phone is totally amazing when I bought it I was totally impressed by its look durability of battery it was mind blowing sound quality is nice but I am not agreed with camera quality of this phone still good but not so and the features of this device are totally unique like 2nd space, dual app etc ram and rom is very good and it never hangs while using a lot and LTE + volte also applicable and charging speed is fine it doesn’t take enough time to charge 100% and the most amazing thing about redmi note 4 is the price of this device
