Apple adds Reachability to iPhone Duo in iOS 27.3 beta
The iOS 27.3 developer beta lets iPhone Duo owners shift the internal display's content with a short swipe to reach the whole interface one-handed.
Apple has added Reachability support to the iPhone Duo in the iOS 27.3 developer beta, according to appleinsider.com. The feature brings one-handed reach to the device's internal display.
With Reachability enabled, a short swipe shifts the left or right side of the iPhone Duo's internal display to the other side. That movement brings the opposite edge of the interface within reach of the thumb holding the device.
The result is that users can reach every part of the interface with one hand while holding the iPhone Duo. The feature is part of the developer beta of iOS 27.3 and is not yet available to the general public.
