Xiaomi was released mi 4 in two different storage systems 16GB and 64GB. mi 4 has a great design and good specifications. but the cost of this mobile was not a value of money, I think One Plus One is the better option with 64 GB internal storage.
I made a conscious decision to avoid the rat race of YU and Mi phones. The phone is powered by Qualcomm’s Snapdragon 801 processor and 3 GB RAM. but 16 GB of internal will not sufficient to any people. expect the internal storage all the features are very good
