what specific features do you see iPhone having that android lacks?
i used iphone for 5 years up through iphone4 with iOS 7.
then switched to samsung android.
there isn't a single thing i found critical/useful on iOS
that i don't have on samsung.
and my samsung phone (galaxy note 2) was cheaper and faster than my iphone4
with a larger screen, battery life, etc...
and honestly, i find samsung's android OS UX more flexible, logical, and efficient than iOS.
