Xiaomi was one of my favourite company because it used to make good phones but I now this is the most bad company I have ever seen because of many reasons so read my review.
Display and Looks :
Display is good in this device because it is a 5.5 inch 1080p full HD IPS display which is very good in when you are using this device in indoor light but if you will use this device in outdoor the screen visibility is not good. This is a very ugly looking device with the camera at the center and flash placed just below the camera and a speaker at the back which is deal breaking thing.
Performance :
As this device is having a 2.0 GHZ octa core processor which performs very well when you using 2-3 apps and if you use more than 3 apps you will notice some frame drops. Games with medium level of graphics will run smoothely but games like Modern combat and Nova 3 which are having high graphic level will not run smoothely.
OS and UI :
It is having android 4.4.4 kitkat and you will not get android lollipop update and on the top it is covered by MIUI and this is the main reason I will never suggest you to buy this phone because you will never get the taste of android Lollipop and MIUI ruins your android experience with its ugly UI and lagginess.
Camera :
This phone is having a 13 MP rear shooter which is having a good exposure level and other things and this results in good quality photos and for selfie this phone is having a 5 MP front shooter so you and your friends look good in your group selfies.
Reccomodation :
I would not recommend this to anyone just because you will never get the taste of android lollipop and if you will get it then its experience will be ruined by the MIUI.
