Apple added Reachability support to the iPhone Duo in the iOS 27.3 beta, allowing owners of the foldable to more easily reach things from the other side of the large internal display. Here’s how it works.
iPhone Duo’s internal display
The iPhone Duo has a massive internal screen, but while you would think it’s ideal for two-handed use, some may still lament the inability to access everything on the screen with a single thumb. As part of iOS 27.3‘s developer beta, that’s no longer a problem for the iPhone Duo.
As part of the update, Reachability will temporarily shift the left or right side of the screen to the other side with a short swipe. This allows every part of the interface to be accessible from one hand that’s also holding the iPhone Duo itself.
