iOS Code Suggests Apple's Foldable iPhone Duo May Feature Mac-like Edge Lighting
Analysis of iOS 27 RC code indicates Apple may equip its first foldable iPhone, reportedly named Duo, with an 'Edge Light' feature similar to that found on Mac computers.

Apple's anticipated first foldable iPhone, rumored to be named "Duo," may feature an 'Edge Light' function, similar to technology currently available on Mac computers. This information stems from discoveries within the code of the iOS 27 Release Candidate (RC).
The "Edge Light" feature, first introduced in macOS, utilizes the edges of a MacBook's screen to provide illumination during video calls. Its purpose is to enhance facial lighting in low-light conditions by simulating the effect of a ring light.
While the code has been identified, the implementation appears to be in development. Reports suggest that the color temperature adjustment functionality, present in the Mac version, is not yet fully realized in the iOS version. The Mac implementation allows users to adjust the width of the white light around the screen and modify its warmth or coolness.
Apple is expected to enter the foldable phone market in the future, and such features could distinguish its offerings. The company has not officially confirmed the development or specifications of a foldable iPhone.
