  • Xiaomi is shipping the Mi 4S with MIUI 7 over Android 5.1.1 Lollipop. Which is very sad for many user as this is Marshmallow time Xiaomi still run Lollipop and other version of also arrived as developer preview so it runs about 2 year old OS.  MIUI has adopted many design pattern of iOS in terms of simplicity and design with topped Android feature so is kind of “iDroidOS”.


  • MIUI offers a stable experience that has been carefully curated and good makeover over the past few versions and while it is missing a few features found in stock Android, it will be comfortable for any MIUI enthusiast to use.
  • The phone is good but best as compared in it’s price range what’s it offer. But overall we look what smartphone gives to us and no doubt to say it is good in terms of all aspect.  It uses Wi-fi 802.11 ac with Bluetooth v 4.1 it also have GPS.

For a person who loves color Xiaomi available this phone in 4 color option of Black,White,Gold and Pink.
