Xiaomi Redmi note 4 has come to the market with unique updated features as a smartphone of 2018 have it’s own bio whereas it’s unique feature are second space, dual screen mode, etc. It’s a perfect phone for modernization temporary look it’s features are amazing it’s android version and os are marshmallow v. 6.0.1 some aspects of the smartphone are we can afford it in low budget and a classy look of course sound quality is very good fast charging only on MI charger although it’s nice you can buy it on e-shopping or in electronics market. Xiaomi Redmi note 4 is a perfect phone for me I am just happy that I bought it. But there is one problem of the phone it will starts to hang if the storage space is full. So we can’t think that we can full the storage 64 GB of phone. So buy it as your wish. Thank you
