Apple’s first foldable iPhone offers a large screen for gaming, videos and multitasking. However, early reports suggest that some popular games are not yet fully optimised for its inner display.
Users playing Genshin Impact and Honor of Kings on the unfolded iPhone Duo have reported black borders around the game. Instead of filling the entire screen, the games run inside a smaller area.
The problem appears to be related to app compatibility rather than a fault with the phone’s display. The games have not yet been fully adapted to take advantage of the foldable screen.
Why Do Games Show Black Borders?

The iPhone Duo has a 7.6-inch inner display that opens into a larger viewing area than a regular iPhone. However, existing apps do not automatically become fully optimised for the new screen.
Apple provides compatibility modes so older applications can continue working without requiring developers to rebuild them immediately.
Apps designed for iOS 26 can run inside a smaller area surrounded by black borders. This helps preserve the app’s original layout, but it also means that some of the inner display remains unused.
Apps built for iOS 27 can use more of the available screen space. Developers who use the iOS 27.1 SDK can support the full compatibility mode designed for the iPhone Duo’s inner display.
This means that the final experience depends partly on how quickly individual developers update their apps.
Can You Make the Games Bigger?
Yes. Reports indicate that users can choose to enlarge the affected games on the iPhone Duo.
However, enlarging an app does not guarantee that it will fill every part of the screen. Black borders may remain, and the game may not have been designed for the foldable display’s full layout.
Users should also remember that stretching an app’s interface is not the same as receiving a properly optimised version. Some interface elements may still appear in their original positions or proportions.
Will the Games Get Full-Screen Support?
Apple has provided developers with tools to optimise apps for the iPhone Duo. Its newer SDK allows compatible applications to make full use of the inner display.
However, there is no confirmed release date for full-screen updates to Genshin Impact or Honor of Kings.
Developers may need to test the layout, controls and performance before releasing updates. Games with complex touch controls require particular care because the larger display can change how users reach buttons and other interface elements.
Until an optimised version becomes available, users may need to continue using the existing compatibility mode or enlarge the game where supported.
What This Means for Indian Buyers
The iPhone Duo starts at ₹2,99,900 in India. Its 7.6-inch inner display is one of its main attractions, giving users more room for gaming, reading, video and multitasking.
However, a larger screen does not automatically guarantee a better experience in every app. Buyers who regularly play specific games should check whether those games support the foldable display before purchasing the phone.
Apple’s official product page provides the latest specifications, pricing and availability information: Apple India iPhone Duo.
App support can improve through software updates, so the current limitation may not represent the phone’s long-term gaming experience. Still, buyers should judge the device based on the software available today rather than assuming every game will be optimised immediately.

Passionategeekz Take
The iPhone Duo’s large inner display offers plenty of potential for mobile gaming, but that experience depends on app developers adapting their software.
The reported black borders in Genshin Impact and Honor of Kings show that some popular games still need optimisation. Users can enlarge the apps, but that does not guarantee a full-screen experience.
This is not evidence of a defective display. It is a reminder that new hardware and software need time to catch up with each other.
If gaming is a major reason for buying the iPhone Duo, check support for your favourite titles before spending ₹2,99,900. Future updates may improve compatibility, but no release dates have been confirmed for these games.
