This review after using the mobile more than 1 year.
When this product was in flash sale in Flipkart I could manage to get one of them. Initially people had review like this is a China Mobile Bla Bla. I use to keep ignoring them. Now I can show them yes this is a China made mobile which is performing awsm even after 1 year, no problem at all till now.
Generally I am rough user so some scratches on the camera glass so the photo quality gone down or else I have no issue with this mobile.
battery is still working fine with more than 8 hrs back up with Internet on condition. Touch sensitivity and processing speed is same like new.
I used to download videos directly through torrents over night, skype call and whats up are very often used SW. so many low volume apps are also installed still working fine.
Now I can say MI proven its quality to me.
