I am using it from oct 2015. And what I feel that its a quality product. Looks wise it a super phone.battery backup is batter, vedios quality are good.camera are good.volume in mp3 player should be more than it has.screen size is 5.5 which is a standard size for nowadays and fit for your pocket and your palm size.inetrnal memory card is of 16 gb which is a enough space for movies and songs you want to store.back flash is very powerfull when it compares to front flash. The only disadvantage is that phone is start hanging after 18 months of use .
Other wise according to a cost of 12000 its a perfect phone.if you want to buy it go ahed.
