iPhone Ultra, Apple Foldable Device Preview
New dummy photos of the foldable display model 'iPhone Ultra,' scheduled for release late this year, have been leaked. You can also see it placed alongside other Apple models for comparison.

As test production of the first foldable iPhone is underway, accessory manufacturers such as protective case makers have already obtained dummy models. Naturally, related photos are already spreading online.

7.8-inch Main Display Close to iPad Mini
In these new photos released by leak expert Vadim Yuryev, models of the iPhone 18 Pro Max, iPhone Ultra, and iPhone 18 Pro are placed side by side. Additionally, you can see the device in both folded state (photo at the top of the article) and unfolded state placed below the iPhone 17 Pro Max, allowing you to gauge the size of the main display. The screen size is 7.8 inches, with a width as wide as the portrait length of a regular iPhone and a height that is taller (71.5mm compared to 111.5mm).

Thickness and Camera Module: Information Revealed by the Leak
In other words, the aspect ratio is 4:3 and the size nearly rivals the iPad Mini (8.3 inches). According to the leaker, the thickness of this dummy when folded is 11mm, contradicting the previous rumor of 9mm to 9.5mm. This likely includes the camera module protrusion, and for reference, the camera module does not span the entire width of the device.

The iPhone Ultra is scheduled to be unveiled in September 2026 alongside the new iPhone 18 Pro and Pro Max models.
