For the iPhone 16, Apple switched away from the square bump for a more slimline approach, while retaining it for the Pro models, but things may change a lot more for the iPhone 17 generation.
There have been quite a few rumors about the iPhone 17 Pro's camera system, many months before Apple actually introduces the new iPhone generation.
On February 14, Jon Prosser shared a video with renders of an iPhone 17 Pro Max design, complete with a full-width camera bump.
Supposedly based on supply chain materials, and appearing at the same time as an image shared by "Jukanlosreve" on X, the camera bump would extend across the entire width of the iPhone.
By February 23, Sonny Dickson shared images of an iPhone in a case, that used the same wide camera bump design.
