Lumia 830 is the best phone that I have ever used I bought this mobile 7 months before and at the beginning I didnt like it much but day by day usage all its extraordinary features made me like it .
It has the best camera clarity with hd recorder but the nly disadvantage is there Is no many number of app as there in android play store but even though it is a defect it prrfect Lumia 830:has the biggest size of screen and all sort of hd videos are supported over here and screen resolution is awesome
