Apple’s Foldable iPhone to Feature Side-Mounted Touch ID, Analyst Confirms

Apple’s first foldable iPhone will mark the return of Touch ID. The fingerprint sensor will not be placed under the screen. This news comes from a reliable industry insider.

The device is widely expected to launch in 2026. It will be part of the iPhone 18 series. This move signifies a major design shift for Apple.

Why Apple is Choosing a Side Button for Touch ID

Analyst Ming-Chi Kuo first predicted this feature months ago. He has now doubled down on his claims. Kuo states that an under-display ultrasonic sensor is unlikely.

Instead, Apple will use a side-button module. This design is common among many foldable Android phones. The component will reportedly be supplied by Luxshare ICT.

This approach offers significant usability benefits. A side-mounted sensor works whether the phone is open or closed. It provides a consistent and reliable unlocking method.

The Practical Challenges of Biometrics on a Foldable

The decision highlights the engineering challenges of foldables. Incorporating Face ID into an ultra-thin device is difficult. The required sensors need a certain thickness to function.

According to Reuters, Apple prioritizes a sleek, minimal design. A side-mounted Touch ID supports this goal. It uses proven technology that Apple already implements in its iPad line.

Using an under-display sensor would have required two units. This would consume valuable internal space. That space is better used for a larger battery.

Apple’s reintroduction of Touch ID solves a key foldable design puzzle. It offers a secure, practical biometric solution for the new form factor. This strategic choice balances innovation with proven reliability.

When will the foldable iPhone be released?

Industry analysts point to a September 2026 launch. It is expected to be called the iPhone 18 Fold. The launch would coincide with Apple’s usual fall event schedule.

Will the foldable iPhone have Face ID?

It is considered highly unlikely. The complex TrueDepth camera system requires space. The ultra-thin profile of a foldable phone makes integrating it very challenging.

What will the price of the foldable iPhone be?

Early estimates suggest a starting price around $2,000. This aligns with current premium foldable phones from competitors. It will be Apple’s most expensive iPhone model.

Why is Apple bringing back Touch ID?

It provides a reliable authentication method for a new device type. It works seamlessly in both folded and unfolded states. It is a practical solution to a complex design problem.

Which company is making the Touch ID module?

Analyst Ming-Chi Kuo identifies Luxshare ICT as the supplier. Luxshare is a major Apple partner. They already manufacture various components for Apple devices.
