The iPhone Duo features two distinct logical viewports for web development:

• Inner Display (Open): 7.6-inch Super Retina XDR folding display with a logical CSS viewport of 890 x 626 pixels (2670 x 1878 physical pixels at @3x density).

• Outer Display (Closed): 5.4-inch Cover OLED display with a logical CSS viewport of 466 x 678 pixels.

Crafted from Grade 5 titanium, the device measures a remarkably thin 5.2mm when open and 11.3mm when closed. It is powered by the A20 Pro chip, features dual 48MP cameras, and comes in two colors: Star White and Night Sky.

Following Apple's keynote announcement, pre-orders for the iPhone Duo begin on Friday, October 16, 2026, with retail availability and carrier delivery commencing on Friday, October 23, 2026.

The dual-gear titanium hinge supports five distinct device postures:

1. Closed: Folded completely shut to provide a standard compact one-handed smartphone experience.

2. Landscape: Open flat held horizontally ideal for multi-column dashboards, video editing, and split-screen layouts.

3. Portrait: Open flat held vertically, perfect for dual-page reading or note-taking.

4. Seated: Resting on a surface like a laptop with the bottom half flat and the top half angled at 90°-110° for video calls or media playback with dedicated controls on the lower display.

5. Standing: Placed like an inverted 'V' in a tent position, displaying clock, calendar, or recipe widgets on the outer screen.
