iPhone Duo 2 Reportedly Planned With Outer-Display Face ID, Action Button, and Telephoto Camera

Bloomberg’s Mark Gurman reports Apple has four goals for future iPhone Duo models: Face ID, an Action button, a telephoto camera, and a thinner, lighter design. Prototypes of the iPhone Duo 2 already put Face ID on the outer display, but the feature may not be ready in time and could land only on the iPhone Duo 3.
