I have mi4i 32 GB first of all it is the best quality phone which give value for each money spend on this phone main attraction is its full HD display and high PPI on 5 inch its camera at its best. front camera is awsome rear is not up to the quality audio speaker is below average but its audiable it support 4g and all common connectivity features this doesn’t support SD card and battery is non removable.
Miui is very nice to use other important con is its heating problem but it can be fixed by software upgradation it is a slim phone less weight battery is above average it is 3300mah this phone currently available in 16gb and 32gb.
I recommend 32gb.xiaomi is one of the largest smartphone makers fastest growing companies its great advantage is less price and great quality mi4i good phone with nice features other important feature is its sunlight display it automatically adjust brightness miui is very customised.it have large community support
