Key Takeaways
- Apple's Reachability feature, originally introduced in 2014, is now coming to the iPhone Duo via the iOS 27.3 update to assist with one-handed use.
- The iPhone Duo's passport-style form factor and wide stance on the 5.4-inch cover screen make it difficult to reach the corners with one hand.
- Reachability on the Duo shifts the screen layout sideways to the left or right based on the direction of your swipe, rather than downwards like traditional iPhones.
Apple’s ‘Reachability’ feature for one-handed use made its debut back in 2014 on the iPhone 6. This feature has found incredible mileage among users as the size of iPhones has progressively increased over the years. The new iPhone Duo’s inner display is intended for two-handed use, but the cover screen makes it hard to reach the corners while operating the foldable with one hand. The latest iOS 27.3 update, which is currently in beta, brings the Reachability feature to the device. Here’s how you can enable one-handed mode on your iPhone Duo.

Reachability on the iPhone Duo
Even though the cover screen of the iPhone Duo is just 5.4 inches in size, the passport-style form factor of the foldable lends it a wide stance. As a result, reaching for the far corners with your thumb while holding the phone in one hand can turn into a struggle. ‘Reachability’ fixes this by moving the screen layout to the left or right side of the panel, depending on the direction of your swipe.
Swiping left on the left edge of the display moves the contents of the screen towards the left. A right swipe on the right edge does the same in the opposite direction. The empty space is filled with dark pixels. The new aspect ratio makes it easy to reach the items on the far side of the screen without bringing your other hand into the action. On a traditional ‘candybar’ iPhone, Reachability shifts the screen interface downwards instead of sideways.
Enable Reachability from Settings

- Go to Settings.
- Tap on Accessibility.
- Scroll to the Physical and Motor section.
- Turn on the toggle switch next to Reachability.
