Last Friday, the iPhone 18 Pro series commenced its initial round of shipments, only to find itself amidst a swirl of attention due to the emergence of circular spots in the top left corner of its screen. This anomaly is intricately linked to the downsizing of the Dynamic Island feature. Apple has repositioned the infrared camera, previously situated beside the front-facing camera, to a location beneath the top left corner of the screen. This strategic move echoes the approach taken with under-display cameras, enabling the infrared camera to capture light through the display panel.

However, this innovative solution is not without its technical hurdles. The sub-pixels and circuitry inherent in OLED screens pose a potential obstacle, as they can obstruct and disrupt the light transmission process. To mitigate this issue and enhance light permeability, Apple has opted to space out the sub-pixels above the camera more generously. Nevertheless, this adjustment has inadvertently led to imperfections, manifesting as graininess and uneven brightness in the affected area.

Apple's decision to implement this design may stem from its aspiration to accumulate experience in anticipation of unveiling a 'flawless phone' boasting a hole-free screen by the time the iPhone celebrates its 20th anniversary in 2027. Nonetheless, the tech giant must also take into account the user experience of those who have already invested in the current device.
