The xiaomi Mi4 is an old phone but it has definitely got a nice range of features which make it still a worthy investment in today’s date.
First of all the screen quality on the Mi4 is simply amazing and also the design of the phone is good.rge camera on the mi4 is good in daylight and above average in low lighting.
The phone has got a snapdragon 801 processor with 3GB ram making it one the best phones in terms of performance and gaming. Although the device runs kit kat out of the box but it might be receiving marshmallow update later. The MIUi runs fine moat of the times.
The one major problem is with the connectivity though, with just single Sim and no 4G. So if can survive without 4G then the Mi4 is an excellent phone.
