I bought the Xiaomi Redmi Note Prime after my mi4i crashed. I personally feel that redmi note is a better option than mi4i. Though it lacks behind mi4i in certain features . Such as the camera clarity and the picture density. But from the storage point of view redmi note prime is far ahead. Having an internal storage capacity of 16gb and supports external sd card expandable upto 32gb this phone is much more smooth. And a 5.5inch HD display making it a perfect phone for the gamers. Several heating problems are there. But overall its a nice phone.
