Multiple outlets report that references to “Edge Light” appear in iOS 27 code, suggesting the feature used on newer Macs could be expanded to a foldable “iPhone Duo.” Cult of Mac says the discovery is in Apple’s own software code, while MacRumors ties the finding to work by code researcher pdfu who has been reviewing changes across Apple updates.
Edge Light on Mac is described as a virtual ring light: it illuminates the borders of the screen in low-light situations, with options to adjust the border width and a color temperature control. MacRumors adds that iOS 27 Release Candidate evidence points to the feature being gated behind a device subtype associated with iPhone Duo, and that the color temperature setting appears incomplete, indicating the feature is still under development. MacRumors also notes that a simulated video suggests the iPhone version may use similar brightness and color temperature controls.
At this stage, outlets emphasize that timing and device availability remain unclear, including whether Edge Light is ready for the iPhone Duo launch or limited to that model.
