Xiaomi mi4 running on kitkat andriod and some good news is its upgrading to lolipop in next fews months and its confirmed news which is amazing news for all xiaomi users so lets talk about mi4.
Best part of this phone is it has 3gb of ram if you searching for a 3gb ram andriod then go for it its best.
With 5.0 inches large display and with metalic body it looks amazing and it runs 2.5 quad core processer plus upgarede miui version7 which make mi4 more smoother moving further it has 16 gb/64gb inbuild memory but no card slots to it
Talk about camera it has whooping 13mp rear with led flash light and 8mp back camera queit amazing right and the main part it has 3080 mah battery which last you long no worry about battery only the bad thing is due to metalic body when you play game or while charging it become somewhat hot otherthan that it is best
Thanks all
