Based on insider leaks, in celebration of the 20th anniversary of the iPhone's initial release in 2027, Apple is gearing up for a substantial design transformation. The objective is to craft an iPhone with a "full-glass, true full-screen" design, where the front of the device has no discernible openings. It's possible that this model will bypass the traditional "iPhone 19" naming pattern and instead be directly christened as the "iPhone 20". This new iPhone is set to integrate cutting-edge technologies, such as an under-display camera and 3D under-display facial recognition, in a bid to attain a full-screen display without any cutouts. Nevertheless, the most recent updates from the industry supply chain suggest that the path to realizing this ambitious vision is fraught with difficulties, primarily due to the intricate technical requirements and exorbitant production expenses.
