Apple is actively testing prototypes of the second-generation iPhone Duo featuring an under-display Face ID sensor, according to reports from Mark Gurman. The initial iPhone Duo launched at a starting price of $1,999 and relies entirely on Touch ID built into its power button. This reliance stems from physical constraints within its 5.2-millimeter thick chassis, which left insufficient room for the TrueDepth camera system required for facial recognition.
Prototypes Testing Under-Display Sensors
The newly tested iPhone Duo 2 prototypes place the Face ID sensor and camera directly beneath the cover screen. Apple is evaluating this under-display technology to solve the space limitations that plagued the first-generation foldable. These hardware adjustments mirror Apple’s strategy with the under-display infrared sensor on the iPhone 18 Pro. Alongside facial recognition, Gurman indicated that Apple is exploring the addition of an Action button, another hardware feature absent from the current model.
iPhone Duo Faces Stock Shortages and Competitor Criticism
The first-generation iPhone Duo is currently facing widespread stock shortages, with resale prices on secondary markets climbing two to three times above retail. Early reviews point out standard first-generation shortcomings, highlighting that the side-mounted Touch ID sensor can be difficult to reach depending on how the device is held. Online communities and technology figures, including MKBHD and Carl Pei, have criticized the lack of facial recognition as a major trade-off compared to competing devices like the Galaxy Z Fold 8 and the Pixel 11 Pro Fold, both of which feature Face ID and dedicated telephoto lenses.
Face ID Implementation for iPhone Duo 2 Remains Uncertain
Apple has not officially confirmed when or if the second-generation foldable will incorporate under-display facial recognition. Successful implementation next year depends heavily on the company’s ability to significantly slim down core optical components, specifically the dot projector and infrared camera. Because tech companies frequently evaluate prototypes that never reach commercial production, industry observers emphasize that the inclusion of Face ID in the final iPhone Duo 2 remains uncertain.
