Its is the really good phone in this price range you can move in to buy this.I have 32/3gb variant.But their are few minor problem with this like its sometime heats up while charging but after a month of use the problem sort outs.The graphic is good while playing games but I dont now why it lags in nova 3 , rest every games I have played it worked fantastic.In some games the phone heats up upto 4°c then the room temperature.And also the phone has 3 Gb of ram of which 1.6 Gb of ram is free after killing all the apps and game but I may waiting for the update for android 6.0 because in it the almost 3/4 of ram gets free.the camera is awesome rear with 16 MP and front with 5 MP the picture quality is good in natural lighting and artifical light ( if it is brigth enough) but the exposer get disturb in low lighting and in flash.Now let us talk about MIUI 7, by the way the interface is awesome fast respone good animation consume less battery, but MIUI 8 is more efficient then MIUI 7 and has better interface.The last thing I want to say is the camara supports the 4k shots but us not mention in the mi camera app but we can shot 4k videos and picture in offical google camera app.it take almost 2hrs to charge from 0-100% .
