Apple has announced its long-anticipated foldable iPhone, the iPhone Duo, which arrives more than seven years after the first Samsung Galaxy Fold hit the market.
Much like Samsung’s recent Galaxy Z Fold 8, Apple says the Duo is a similar size to a passport when closed, with a 5.4-inch display, but opens to a 7.6-inch panel, the largest on any iPhone yet. Both screens use the exact same aspect ratio, and the large inner screen is 50 percent larger than the screen on the new iPhone 18 Pro Max, and 80 percent bigger than the iPhone Pro’s.
The phone’s frame is primarily titanium, strengthened with internal ceramic fibers three times stronger than grade 5 titanium. There’s toughened Ceramic Shield glass on the rear, and Ceramic Shield 2 on the front. An IP68 rating should guarantee safety from both dust and water. It’s launching in two colors: star white, and a dark blue called night sky.
While you’ll see a selfie camera tucked into the rounded corner of the front screen, you won’t see the usual iPhone Dynamic Island or Face ID cameras.
Rumors have swirled about a folding iPhone since at least 2017, when it was optimistically reported that production might begin in 2020. Since then, rivals including Samsung, Google, Huawei, Oppo, Honor, and more have released myriad foldable Android phones, including larger book-style models, smaller flip phones, and more recently trifolds. The market has remained relatively small, though — just 1.6 percent of all smartphone sales in 2025.
