People love redmi note 4. Because of its cost& low price and its storage of 64GB octocore prossesor.
It has very good quality camera and nice finger printing sensors.
I have redmi note it hangs because of high work load but what can u expect on that price.
It metallic body looks very good and the body of phone is strong.
It have android 7 which makes this phone a nice and valuable for what u invest in this phone.
If u want cheap phone with best feature just buy mi note 4.
