Redmi 4 is good and perfect phone. I purchased it before 5 month. Its performence very high. Its main feature that have 4 gb ram and 64 internal and main purpose it have 4100 battery backup. It is the best feature of this phone we can use it one and half or two days with network. Camera back cam 13mp and front cam 5mp good lenses they used to it because high claritty. At last we can give high performence in small cash.
