Xiaomi is on an elevator of success. It provide people what they want. They set the price in such a way that you cannot turn your face away from theur product.
Mi 4i is one part of Xiomis success in world of mobiles. This mobile is now available within?10k.
If you want to buy a phone having same featyres from another company then you night have to spend double.
A long life battery of more than 3000 mah with 2 gb ram makes a good impression. It has 16gb internal memory with 13+ 5 mp camera.
Quadcore processor and a 5 inch display with smooth back makes it look good.
It only problem with this phone is its qualty of screen. Mi 4i touchscreen is very weak. A small amount of force can even turn the single screen into pieces.
Conclusion: A nice phone to have but dont play with the screen physically.
