Analyst Disputes Claims of Foldable iPhone’s Under-Display Fingerprint Reader, Suggests Side-Mounted Touch ID Sensor Will Be Used Instead

Recent insights into Apple’s upcoming iPhone 18 series suggest that it may also introduce the long-anticipated foldable iPhone. This innovation is expected to integrate unique design features intended to differentiate it from competitors in the market. Notably, renowned analyst Ming-Chi Kuo has previously indicated that the foldable model will forego Face ID technology in favor of a side-mounted Touch ID sensor for biometric authentication. Despite speculation about the possibility of an under-screen fingerprint scanner, Kuo has remained firm in his predictions regarding the device’s design and features.

Touch ID Set for Foldable iPhone: Supplier Insights and Features Confirmed

As the launch of the foldable iPhone approaches, slated for the fourth quarter of 2026, speculation regarding its features is rife. However, Kuo’s confidence suggests that the device is unlikely to include Face ID technology. His earlier statement regarding the introduction of a side-mounted Touch ID sensor has not changed, reinforcing the probability of this authentication method being employed. According to Kuo, Luxshare, a prominent supplier for Apple, has been designated to supply the Touch ID module for this new device, further legitimating his forecasts.

The decision to exclude an in-screen ultrasonic fingerprint sensor could be attributed to reliability concerns. Such systems often struggle with accurate readings if the user’s finger is obstructed by a barrier like water or a glove, leading to potential inconvenience. Moreover, the foldable iPhone is rumored to adopt a book-style configuration akin to Samsung’s Galaxy Z Fold 7, necessitating dual displays. Consequently, this design element could require the integration of two fingerprint sensors, making the side-mounted Touch ID a more practical choice.

Six months ago, I predicted the foldable iPhone would use side-button Touch ID. There are now market rumors that it will adopt an under-display ultrasonic fingerprint sensor, but I think that’s unlikely. It’s expected that Luxshare ICT will supply the side-button Touch ID module… https://t.co/KsGu49JXkP

Furthermore, Apple has a history of successfully integrating Touch ID sensors in products such as the iPad Air. This established presence in the supply chain means that sourcing these components for the foldable iPhone will likely be more cost-effective than initiating a new production line for an under-display fingerprint sensor.
