Apple’s Mac Edge Light feature could expand to the iPhone, according to an unconfirmed code finding shared by researcher pdfu on X. The post points to iOS 27 release-candidate code and a device subtype that appears to reference iPhone Duo.
This is not an Apple announcement, and it does not prove that Edge Light will ship at launch. Apple already documents the Mac version as a virtual ring light that uses the display edges to brighten a face during a low-light video call.
What is confirmed on Mac
- It uses the screen edges as a soft video-call light.
- Brightness and color temperature can be adjusted.
- It reduces the effect near the cursor.
- Apple requires an Apple silicon Mac with macOS Tahoe 26.2 or later.
Apple’s Edge Light support page confirms the Mac requirements. The original post from pdfu’s X account says the iPhone color-temperature control is not fully implemented in the code it examined.

A screen-based light could help with calls in dim rooms, especially on a large foldable display. Apple’s iPhone Duo announcement does not mention Edge Light. MacObserver’s iOS 27 hardware guide explains why features may depend on a specific device.
What remains unconfirmed
Apple has not confirmed supported models, controls, brightness, timing, or whether Edge Light will remain in iOS 27. Treat it as a rumor until Apple publishes more. Would you use an iPhone screen as a video-call light?
The rumored expansion would be useful only if the display is bright enough to illuminate a face without making the call distracting. On Mac, Apple provides controls for the effect and limits its reach around the cursor, which shows that the feature is more than a simple white border. None of those controls are confirmed for iPhone. Code can point to a capability that is later disabled, delayed, or limited to internal testing, so the device subtype is evidence of development rather than a shipping promise.
