I am using Mi4i since July 2015. First attractive thing in this phone is weight of this phone which is very low and because of this the phone very much fit in your hand. secondly the display quality(color combination) is fantastic as similar as i-phone. it never hang or heat up. its camera quality is also very good. but there is one drawback of this phone is its memory(ROM) which is not extendable and inbuilt. you have only near by 12 GB storage space. but on whole if you ignore the storage space then in overall this phone is very good for your use.
