Best set and which I m using now. This is so fast, I m using till 8-9 month required but till now this set is not hanged. And 4g set enable and battery capacity is long time. As if u changed just 2-3 hrs it will required full day. And sound quality is good but as u can say average. And camera 13mp front camera 5mp. Not so bad. Its good. U can buy this.
