A newly-discovered iPhone 14 Pro prototype features one of the earliest known incarnations of Apple’s scrapped haptic button project.

Back in July of 2024, AppleInsider published exclusive imagery of a prototype iPhone 15 Pro Max equipped with Apple’s long-rumored haptic buttons. Developed under the codename Project Bongo, the haptic buttons were supposed to make their debut in 2023 but never ended up on mass-production units.
