I have bought this phone 6 month before. I dont have any problem till date. Price is very cheap compare to other phones. Other compny doesnt give such a feature in less price.
It has very good resolution camera. It has 8 MP primary camera and 2MP secondry camera.
But problem is that compny is not having customer care in every city
I updated mine to MIUI 7 it runs smoothly that MIUI6 . it optimized my RAM consumption. and it works great.
the mobile was superb.net speed excellent.charging capacity really good.
