Xiaumi redmi note4 is a mid budget smart phone.But it disappointing me because the camera of note4 is very bad. despite it has a good megapixl but the image quality of this phone is not satisfied. The low light performance is worst. If you want good camera phone then note4 is not a good choice.its sound system I also a notable thing it has a speaker at the bottom .but it’s sound quality is not good as the note 3.so that’s 2 reason is enough for avoid to buy this phone.
