9to5Mac - Gurman said adding a Telephoto camera to a future iPhone Duo is “on their list,” but he does not know when it might arrive.

9to5Mac - Gurman said a Telephoto camera would be difficult to add because of the depth required, describing it as “purely a physics issue.”

9to5Mac - Gurman compared the possible screen-size increase to Apple’s Pro-line growth from 6.7 inches on the iPhone 15 Pro Max to 6.9 inches on the iPhone 16 Pro Max.

WHEN:

9to5Mac - Gurman discussed a third-generation iPhone Duo planned for 2028.

Apple is testing prototypes of the iPhone Duo 2, with changes aimed at addressing an early complaint about its foldable phone. The models under evaluation include Face ID hidden beneath the outer display, along with the possibility of adding an Action button. Apple reporter Mark Gurman also discussed a larger screen for the third-generation iPhone Duo, planned for 2028. He expects its inner display to grow by roughly half an inch from the current 7.6 inches, reaching the high sevens or very low eights, rather than 8.5 or 9 inches. Gurman compared that increase with the growth in Apple’s Pro Max displays across two generations. A Telephoto camera is also on Apple’s list for a future Duo, but there’s no known timeline. The main obstacle is the space the camera requires, which Gurman described as a physics issue, not a cost issue.
