iPhone Fold first leak: dummy units show 5.5-inch cover and 7.8-inch inner display

Apple's first foldable iPhone — widely referred to as the iPhone Fold — has appeared in physical dummy-unit form for the first time. The units, sourced from Apple Asian case-makers and verified by two independent supply-chain analysts, show a book-style design with a 5.5-inch cover display and a 7.8-inch inner display when unfolded.

The dummy units are typically machined from CNC aluminum and used by case manufacturers to prototype accessories ahead of launch. They reveal the device physical dimensions and button placement, but not the internal specs or the final industrial design.

What do the dummy units show?

The dummy units confirm a side-mounted Touch ID sensor (replacing Face ID on the iPhone Fold for space reasons), a USB-C port on the bottom edge, and a triple-lens rear camera array in the upper-left corner. The inner display appears to have a 4:3 aspect ratio when unfolded, making the device slightly more square than the iPad mini.

Apple has engineered a custom hinge mechanism that, when closed, leaves no visible gap between the two halves — a meaningful engineering feat given that competitors like the Samsung Galaxy Z Fold 6 have a tapered gap.

The dummy units are 4.2mm thick when unfolded, making the iPhone Fold the thinnest foldable on the market at launch. The device weighs approximately 240 grams, putting it between the iPhone 16 Pro Max (227g) and the iPhone 17 Pro Max (slightly heavier).

How do the dummy units compare to leaks from earlier in 2026?

Earlier Bloomberg and supply-chain reports (January-April 2026) suggested a 5.5-inch cover and 7.8-inch inner display. The dummy units confirm both dimensions. The earlier reports also suggested a 4.2mm unfolded thickness, which the dummy units confirm.

One detail that has changed: the front camera placement. Earlier reports suggested two separate pinhole cameras (one on the cover display, one on the inner display). The dummy units show only one external pinhole and what appears to be an under-display camera on the inner display.

Why is Apple using Touch ID instead of Face ID?

Three reasons:

1. Space. The foldable form factor has a thinner internal volume than a traditional iPhone. Face ID requires a sophisticated dot projector and infrared camera array that takes up significant internal space.
2. Reliability. Apple has historically had reliability issues with Face ID components in foldable prototypes. The mechanical stress of folding and unfolding can misalign the Face ID components.
3. Cost. Touch ID is significantly cheaper than Face ID. On a $1,999+ device, this is a meaningful cost saving.

Touch ID on the iPhone Fold will likely be embedded in the side button (similar to the iPad Air and iPad mini), not under the display.

How durable is the iPhone Fold?

The dummy units do not show internal components, but supply-chain reports suggest:

• Hinge rated for 200,000+ folds (the industry standard for foldable phones)
• Inner display using ultra-thin glass (UTG) with a plastic top layer (similar to Samsung Galaxy Z Fold series)
• Outer cover display using Ceramic Shield 2 (the same as iPhone 18 Pro)
• IPX8 water resistance (can survive submersion in 1.5m of water for 30 minutes, but no dust resistance rating)

Apple Store employees will receive specialized training for in-store iPhone Fold repairs and screen replacements. The inner display can be replaced as a single component, but the process is more involved than a standard iPhone screen replacement.

How does the iPhone Fold compare to Samsung Galaxy Z Fold 8?

Spec	iPhone Fold (rumored)	Samsung Galaxy Z Fold 8 (rumored)
Cover display	5.5 inches	6.3 inches
Inner display	7.8 inches	7.6 inches
Chip	A20 Pro	Snapdragon 8 Gen 4
RAM	12GB	12GB
Battery	5,400 mAh	4,800 mAh
Thickness (unfolded)	4.2mm	5.6mm
Weight	240g	268g
Starting price	$1,999	$1,899

The iPhone Fold will be thinner, lighter, and have a larger battery, but will cost $100 more than the Samsung equivalent.

How accurate are these dummy units?

Dummy units are typically about 90% accurate in dimensions and button placement, but are not final industrial design. The final iPhone Fold will have the same overall dimensions but may have different chamfers, materials, and finish. Case makers use dummy units to design cases that fit the production iPhone, so the dimensions are the most important detail.
