iPhone Duo includes Edge Light, the virtual ring light first seen on Macs
The iPhone Duo includes a software feature called Edge Light, according to a MacRumors report published October 21. The setting works like a virtual ring light during video calls, brightening the borders of the screen so that light falls evenly on the user's face in dim conditions.
MacRumors says the option appears in apps such as FaceTime, which is the only app it names. The outlet credits Miles Franklin, who pointed out the feature on X. The report does not say how Franklin spotted it, and it does not include any statement from Apple about how Edge Light behaves on the new device.
