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’s biggest event of the year is just weeks away. Here’s what we know about the expected September launch of the iPhone 17—and maybe a surprise or two. The biggest tech event of the year is likely just several weeks away.
