Xiaomi Redmi Note 4 is a copy of redmi note 3 only difference between note 3 and note 4 is redmi note 3 has 650 octa core processer and redmi note 4 has 625 octa corr processer.
Redmi note 3 and 4 is actully good smatphone as compare other smartphone brands.
Main problem which I detect is it get too much hot on high using due to it’s metal body
I don’t think redmi note 4 as user friendly its settings and other tools are just ordinary.
One of the corn is that redmi note 4 is not that much stylish and cool as others.
Last thing it is an good smartphone and value for money but not stylish.
