This is good budget extreme feature smart phone so I was purchased that .The sound quality is not so good but bad .its normal .and its design was totally different from other and unique also. and most acceptable thing is the battery is removal so its quite great & the back side curved design is most impressive & very easy to use .
& the feature are the best and the battery back up is osom.(3000mAh)& battery durability is 2x longer then other mobiles .its is totally a gaming phone so I buy.
I choose that one bcoz its unique and quite different from other.
