It is great mobile I ever used mobile like this before, there are some features I would like to share with u Redmi Note 4 doesn’t support NFC, but all other connectivity bases are covered with dual band 802.11ac WiFi, latest bluetooth , GPS and GLONASS, USB OTG and a fingerprint scanner at the rear. the Redmi Note 4 has a 13 mega pixel camera, f/2.0 camera with dual-tone flash at the rear and a 5 mega pixel camera at the front which give best selfi all the time .the performance of this redni note 4 is mind blowing and the price is also low.
