Apple’s iOS 27.3 developer beta adds Reachability support for the iPhone Duo, enabling one-handed access to content on the device’s display. The feature temporarily shifts the left or right side of the screen so users can reach interface elements using a thumb while holding the foldable.
Across coverage, outlets describe Reachability as working by performing short edge swipes to shift content from one side of the display to the other. Apple also includes a way to control the feature in the iOS Accessibility settings, where it can be enabled or disabled.
The main differences in reporting are at the level of instructions and emphasis. MacRumors includes specific navigation steps for turning Reachability on or off and notes its default state after updating, while AppleInsider and 9to5Mac focus more generally on the purpose—improving one-handed use on the iPhone Duo—along with a high-level explanation of the screen-shifting behavior when using Reachability.
