I will glad to tell you that the product is very nice cheap and handy. The brand which is running like fire in India and other country I am using mi product from 1.5 years and I am very happy with the results . More likely to say the mi 4 is one of the best phone under bujdet mobile phone it has almost all features and some new features are also added like splitscreen. Update s are on time never any problem but some times hangs it an common issue for all mobile phone finger sensor is excellent and touch pad is well. No other complains although phone is good.
