I use this mobile in one month in one month I am not understand this feature because its mobile colours is same like China mobile colour.for example not a 16mp colors.
Therefore I refused it mobile.another major problem is android version is kitkat today using lollipop latest.and not its mobile is rootable.same problem like s3 zapya app when using this is hang and automatically turn on and off.most people think that how that knows you.so brothers I work a large mobile shop where o use and check most of mobiles therefore I acknowledges this problems.And other features like 1 gp ram and processor is good.and large screen.
