Apple Aiming to Upgrade the iPhone Duo in Four Ways

Bloomberg's Mark Gurman today said Apple has four goals for future iPhone Duo models: Face ID, an Action button, a telephoto camera, and a thinner-and-lighter design. Gurman said Apple has already developed iPhone Duo 2 prototypes with Face ID on the outer display, but it is "running out of time" to finalize the feature for that model, so it might not arrive until the iPhone Duo 3.
