Apple Tests Under-Display Face ID for iPhone Duo 2 Amid Launch Supply Crunch

Key points

• Mark Gurman reports that iPhone Duo 2 prototypes include Face ID sensors integrated beneath the outer display.
• The first-generation iPhone Duo relies on Touch ID due to space constraints, a major point of criticism from reviewers and users.
• Apple is also exploring the addition of an Action button for future models, though confidence in this feature is lower.
• The first-generation iPhone Duo launches with limited stock, with pre-orders backordered until January 2027.
• Apple has not finalized whether Face ID will ship with the second-generation model or slip to the third.

Background

The first-generation iPhone Duo, priced at $1,999, launched on October 23, 2026, with significant supply constraints. Earlier reports indicated that Apple might delay Face ID and telephoto camera features to the third generation due to physical limitations in the thin foldable design. The current model uses a side-button fingerprint sensor, similar to the iPad, which many users found inconvenient compared to facial recognition.

How outlets are covering it

9to5Mac and MacRumors both cite Mark Gurman’s report that Face ID prototypes are being tested for the iPhone Duo 2, noting that the technology may not ship until the third generation if development slips. PhoneArena emphasizes that the lack of Face ID is the biggest flaw of the current model, comparing it unfavorably to competitors like the Galaxy Z Fold 8. Macworld highlights that while the first-generation device has strong reviews, the absence of Face ID is a significant drawback, and suggests that waiting for the second-generation model might be more practical given the current supply issues. All outlets agree that Apple is actively working on miniaturizing the TrueDepth system to fit the foldable design, but none confirm that the feature will definitely ship with the next model.

Why it matters

The inclusion of Face ID in the iPhone Duo 2 would address the most significant criticism of the current model, potentially making it a more competitive option in the foldable smartphone market. It also signals Apple’s commitment to improving the user experience of its foldable devices, which could influence consumer adoption and market share in the high-end smartphone segment.

What to watch

Apple is expected to finalize the features for the iPhone Duo 2 in the coming months, with a potential launch in the fall of 2027. If Face ID does not ship with the second-generation model, it may be delayed to the third generation. Consumers should monitor Apple’s announcements for updates on the availability of the device and its features.
