I am using this mobile for last one month and I have no issue about this mobile. It is a very good mobile with great sound quality. The look of Redimi 4 is very beautiful. The mobile price is very affordable.It start from 7K. The camera of this mobile is also very good.
It has good speed because RAM is 2gb. Redimi 4 graphics are very nice. The battery backup is also very good. I like Redimi 4.
