As noted by Miles Franklin, the iPhone Duo's inner display supports Edge Light, an optional setting that debuted on Apple silicon Macs last year. On video calls in apps like FaceTime, Edge Light illuminates the borders of the screen to evenly illuminate your face in low-light conditions. The feature is essentially a virtual ring light.
The feature brings the Mac experience to Apple's foldable phone, letting users brighten their faces during calls without external lighting. Edge Light works by using the display itself as a light source, which makes it especially useful for video calls taken in dim rooms or during evening meetings.
Apple's launch timing is also drawing attention. Apple retail employees have reportedly been told to warn customers against visiting stores to buy an iPhone Duo without a pre-order on Friday, October 23, as there will likely be no stock available for walk-in purchases on launch day. Staff have been instructed to discourage customers without pre-orders from coming in.
Bloomberg's Mark Gurman has also weighed in. Despite knowing the iPhone Duo would face "severe supply constraints" due to manufacturing challenges, Apple chose to begin pre-orders on Friday instead of waiting until it had more inventory ready. Gurman called the decision a "major mistake." With just three days until release, Apple has also begun showing screenshots of its built-in apps running on the device, offering a closer look at how the phone will work day to day.
