GoKawiiliFixit teardown finds iPhone 18 Pro's variable aperture hard to repair
iFixit's teardown of the iPhone 18 Pro examined the new variable aperture system, an under-display Face ID infrared camera, and a larger vapor chamber. During disassembly, a tiny aperture blade popped loose, suggesting that any malfunction in the mechanism would likely force a full replacement of the main camera assembly rather than a simple fix.
