Apple is actively testing prototypes of a second-generation iPhone Duo that incorporate under-display Face ID beneath the device's exterior screen, according to Bloomberg reporter Mark Gurman. The development comes just as the first-generation foldable begins reaching customers at a price of $2,000, bringing a major hardware overhaul to the company's newest product line. [2][3]
The original iPhone Duo revived Touch ID rather than facial recognition, a design choice driven by the foldable's ultra-thin displays, multi-orientation usage, and manufacturing costs. Early reviewers cited the absence of Face ID as a key frustration. Alongside hidden facial-recognition sensors, Gurman noted that Apple is also exploring whether to add its customizable Action button to the next model. [2][3]
While prototype testing does not guarantee a feature will appear in next year's model, the effort reflects Apple's broader push to shrink sensor arrays under glass, building on hardware adjustments seen in the iPhone 18 Pro. If engineering challenges delay the integration, Gurman indicated the technology could slip to a third-generation foldable release. [2][3]
