I am using this mobile from past 1 year and its awesome, it contain 3gb ram and 64gb memory and it dosent have external memory option. it is fast as I bought this mobile.and design of the phone is very classy and it is very slim and handy. I bought in black color and back of the phone is sanded so it never slip from hand. it has many feature in it. its touch very smooth. sound quality is also good
and most important thing is its best phone in this range. Picture quality of phone is too good. all and all this phone is best ever.
