Apple is expected to prioritize upgrades for the third-generation iPhone Duo, with Bloomberg’s Mark Gurman predicting the next model will add Face ID and a telephoto camera. The iPhone Duo launched with Touch ID and dual rear cameras, and Gurman’s view is that Apple’s earlier choices reflect physical and design constraints.

In Gurman’s account, fitting both Face ID depth sensing and a telephoto lens into the iPhone Duo is challenging because of the device’s thickness when unfolded—reported as about 5.2mm. Gurman frames the issue as a “physics problem,” suggesting Apple may rely on component miniaturization and improvements in AI and computational processing to reduce the amount of specialized hardware needed. Across both reports, Face ID and telephoto are described as top priorities, though specific engineering details are speculative.

The iPhone Duo is scheduled to launch on October 23, according to the MacRumors report, while NDTV focuses on the constraints and Gurman’s reasoning for why these features may be delayed until the third generation.
