Xiaomi mi4 is a beast of smart phone, I loved using mi4 till now past a year .let me start with specs
5 inch FHD corning gorilla glass
2.5ghz snapdragon 801 processor
3gp ddr3 ram
16gb internel memory( 12gb usable)
13 mp rear 4k camera and 8mp front
6. 3080ma battery
The phones operates like a butter and its fantastic rear and front camera
And cons now
Phone heats up too much while playing games
16 gb is not sufficient for guys who are game lovers but you get 64gb varient
Wifi network antenna is weak
Thats it.i give a thumbs up and device is available for 15k and its still worthy
