Jon Prosser, the leaker currently facing legal action from Apple over alleged iOS 26 disclosures, has released another video on Front Page Tech that presents what he believes is the finalized look of the rumored iPhone Ultra.

Alongside updated renders compared to prior releases, Prosser references iOS 27 developer builds to support his assertions about the device's existence and a multitasking tool that iOS users have sought for years.

What Does the Newest Leak Reveal About the iPhone Ultra?

The images depict a book-style foldable that Prosser calls a chunky iPhone when shut and an iPad when open, details already familiar from earlier reports. Unfolded, the device may measure just 4.5 mm thick, thinner than the 5.6 mm iPhone Air.

Updates from the Prior December Disclosure

Front Page Tech posted a comparable video in December 2025 that referred to the foldable as the iPhone Fold rather than iPhone Ultra. Comparing the two releases side by side reveals several adjustments.

The earlier video placed the power button with integrated Touch ID at the top edge above the camera bar when the display faced forward, while the new renders move volume buttons to that spot and add a speaker grille on the top edge.

The power button now sits on the right edge in its usual iPhone location but only on the lower half of the device. This arrangement differs from standard iPad layouts and could require some adaptation.

The most noticeable shift involves a smaller camera visor that no longer spans the full width of the back panel. It now surrounds only the dual rear cameras, raising the lenses above a flat surface for a cleaner appearance.

Details on the Upcoming iOS Capability

Prosser states the iPhone Ultra will introduce split-screen multitasking to iOS, though the feature would remain limited to the foldable model. Current iPhones would likely stay without it even after updating to iOS 27.

Apple seems to be preparing the groundwork in iOS 27 code through references such as fold state and angle degrees in the developer beta.

After WWDC 2026, Apple also asked developers to support a wider variety of screen sizes and aspect ratios. If accurate, the iPhone Ultra would mark the first iPhone able to display two apps side by side effectively.

Additional details about the device, including the A20 chip, C2 modem with satellite 5G support, and pricing above $2,000, stay consistent with prior reports. It remains unclear whether the model will include Touch ID or a Camera Control button, though a September 2026 release alongside the iPhone 18 Pro and iPhone 18 Pro Max appears probable.
