I bought this device with great interest but had to sell after a month of use. I believe signal reception and call quality are two primary things we look for in a phone apart from the variety of other features which are available. It poor in both the departments.
The UI is interesting but definitely not easy to use. I think Xiaomi made a decent effort to make an inexpensive phone with variety of features but failed miserably with this model. The UI lags perfection, the phone hangs too often, signal and sound quality is weak. The camera is not upto the mark. Though the photos look bright, they look un-nautural. considering the price point it is sold us I think we have better options in the market today. Definitely not recommended.
