Apple is reportedly testing a quad-curved display for its 2027 anniversary iPhone, according to Weibo leaker Digital Chat Station. The design would wrap around the device's corners, creating a bezel-free all-screen experience. This comes as Apple works toward a fully cutout-free display for the special 'iPhone 20' model launching next year.

The quad-curved display represents a significant departure from Apple's traditional flat-edge design philosophy. Previous reports suggested Apple was considering haptic buttons to replace physical ones, which would complement the curved display approach. The company has been experimenting with under-display components including camera and Face ID technology, though progress has reportedly been challenging.

While Apple's exact timeline remains unclear, the leaker indicates this design direction is still active. Even if Apple can't achieve a completely cutout-free display, the curved edges alone would mark a notable design evolution for the iPhone lineup. The 20th anniversary model appears to be pushing Apple's design boundaries in multiple directions simultaneously.
