Apple Says 'Reachability' Feature Coming to iPhone Duo Later This Year
by Joe Rossignol · MacRumorsApple plans to add Reachability support to the iPhone Duo in a software update coming later this year, according to WIRED's Julian Chokkattu. The feature will presumably be available on both the inner and outer displays, but the article did not say.
Available on other iPhone models, Reachability is an accessibility setting that allows you to swipe down on the bottom edge of the screen to lower the top half of the interface so that controls are easier to reach with one hand.
