I bought Redmi 4 from online. I am still using Redmi 4. It is very nice product. I am using this mobile 2 years continuesly. There is no complaints till now. It has good camara and 4000 mh battery. There is no hang. It is user friendly mobile. It has 5 inch display. So it is easy to handle. It is not more size. It's storage is 3 GB ram and 32 GB internal. Main advantage of this mobile is that low price.
