What I want to be able to do is to be able to take gameplay screenshots, and then have the ability to use AirDrop on iOS to share on Twitter.
The reason is viral spreading of games through this method as users post game images with text we define (but they can customize) to places such as Twitter or Facebook. Generally ask user to share in WOW moments where they would really want to show off and share.
I think there are comparable features with Android but not sure at the moment.
