Redmi note 4 is very good phone the quality is nice. As in pervious phone of redmi the battery is awsome in the note 4 they use the same battery as they did in note 3 and 3s prime the screen size is 5.5 inch the people who like big screen phone is Happy with that the sound quality is also very good. I expect OIS in the camera of note 4 but xiaomi didn’t do that I hope they do this in note 5.
