As to my knowledge I have never seen such a mobile phone with lots of unique mobile features even you will never get such features in 15000 Rs.It comes with 5 inch display that is pretty much HD.As to its physical appearence I dont think there is any phone in the which can compete it in designing.It is made of full metallic body with the diamond cutting that gives two brighter strips in rear to it.There are three variants is available in market of MI REDMI4 2gb, 3gb and 4 gb.The thing that make me buy this phone is its battery capcity 4100 mah. Its sound quality is good.The cheapest variant worths only 6999 Rs.You can buy it from flash on amazon or MI store.
