A new leak suggests that the material that is used in the next Pro iPhones will be a significant departure from recent years.

This year’s iPhone 17 Pro and Pro Max will have the same screen sizes as last year: 6.3 inches on the Pro, 6.9 inches on the Pro Max. Aside from size, Apple sometimes differentiates its Pro models through a special camera feature. The Pro Max model, at times, gets a new camera capability a year or more ahead of its smaller sibling.

Apple is expected to unveil the iPhone 17 Pro Max alongside the iPhone 17 series in September, with major upgrades in design, performance, and cameras.
