Breakthrough features revealed on Apple's first foldable iPhone.

According to Mark Gurman, Apple's first foldable iPhone will be designed to open like a book, revealing a large screen inside, similar to existing foldable Android smartphones.

The highlight lies in its four-camera system, including one on the front, one inside, and two on the back. This arrangement allows the device to function flexibly as a regular iPhone when folded, with an outer screen of approximately 5-6 inches and a selfie camera.

When unfolded, the large 8-inch screen will activate an additional internal camera that acts as an active front-facing camera. Meanwhile, the rear camera cluster includes a high-resolution main lens and a secondary lens, most likely an ultra-wide or telephoto lens.

Notably, Apple may revert to Touch ID instead of Face ID for biometric security. This is due to the challenge of thinness; the device, when folded, is predicted to be only about 9.5mm, meaning each half is less than 5mm – thinner than any previous iPhone model. With this limitation, the complex TrueDepth system used for Face ID would be difficult to integrate, and Apple will most likely place Touch ID in the power button on the side.

In terms of connectivity, the foldable iPhone will use an internal cellular modem developed by Apple. Following the C1 modem chip already present in the iPhone 16e and the upcoming iPhone 17 Air, the foldable version is expected to be equipped with the next-generation C2 modem, supporting even higher speeds. Like future iPhone models, this device will completely eliminate the physical SIM slot, supporting only eSIM.

Despite being a groundbreaking product, the popularity of a foldable iPhone will largely depend on its price. High-end foldable Android smartphones currently cost $1,800 or more, and it's unlikely Apple will offer a lower price.

According to Gurman, the device will only come in two basic color options: black and white. Manufacturing partners are expected to begin ramping up production early next year, preparing for a launch in the fall of 2026.

This is just the beginning of Apple's ambitious design roadmap. After the foldable iPhone, the company is expected to introduce a professional-grade, all-glass iPhone model in 2027.

This year, users can expect the iPhone 17 with a design that is almost unchanged from the iPhone 16, except for the new rectangular camera module and the appearance of the iPhone 17 Air - the thinnest iPhone ever.
