Apple just hit a wall on the one thing they’ve been trying to perfect for almost a decade—and it could completely mess up the iPhone 20. In this video I break down the latest leak around the 20th anniversary iPhone, the one that’s supposed to finally give us that “single slab of glass” dream: no notch, no Dynamic Island, just an uninterrupted full-screen display. That’s the vision, and it’s exactly why the iPhone 20 is being hyped as Apple’s biggest design moment since the iPhone X. But here’s the problem: to get that true all-screen look, Apple has to hide both the front camera and Face ID under the display, and that’s where everything falls apart. Under-display cameras still take a hit in sharpness and low-light performance, and Face ID can’t be “almost good”—it has to be instant and perfectly reliable every time. According to Fixed Focus Digital, Apple is still a long way off from solving both together, which could force Apple to keep a cutout… just smaller. And if the iPhone 20 ends up being a polished version of what we already have, that expectation gap is where the excitement dies.
