Manufacturing facilities in Apple’s supply chain have finished renovations required for iPhone 20 production, according to a Weibo leaker known as Fixed Focus Digital. The move confirms that Apple’s 20th-anniversary iPhone, internally codenamed “Glasswing,” is on track for its expected fall 2027 launch and represents a tangible acceleration in the device’s path from design concept to mass production.
The leaker did not name the specific supplier, but mentioned that the facility has already been renovated and is now waiting for machining to begin. Most iPhone production ramps occur much closer to launch, so this early preparation suggests the engineering complexity of the all-glass design demanded earlier capital investment and planning.
The iPhone 20 will mark Apple’s return to an all-glass chassis after more than a decade of aluminum frames. Fixed Focus Digital said the “preferred approach” for the device is a full glass design, with manufacturing quality expected to reach the level of the first-generation iPhone Air. Apple is aiming for a “mostly glass, curved iPhone without any cutouts in the display,” with curved glass wrapping around all four sides of the device.
Two anniversary models are planned, sized similarly to the iPhone 18 Pro and iPhone 18 Pro Max, suggesting screen sizes of 6.3 and 6.9 inches. Apple’s curved-glass iPhone 20 is positioned as a premium design statement distinct from the utilitarian iPhone 18 lineup, which will retain aluminum mid-frames. That split strategy shows Apple’s intent to position the anniversary iPhone as the design flagship, not an incremental update.
Realizing an edge-to-edge glass slab required technical innovation beyond glass manufacturing. Apple is using Samsung-manufactured micro-curved OLED displays that are brighter and thinner than existing panels. Samsung is building an equal-depth quad-curved panel with a shallow micro-curve that avoids the aggressive curvature of some prior Samsung designs.
Apple’s adoption of Samsung’s Color Filter on Encapsulation technology is the key enabler. This process applies the color filter directly onto the encapsulation layer rather than as a separate polarizer layer on top of the display. Overall thickness is reduced and light transmission increases, helping the display blend with the glass edges. The iPhone 20’s “slab of glass” appearance depends on Samsung’s manufacturing precision as much as Lens Technology’s cover glass.
All three of Apple’s major 2027 product releases, the iPhone 20 included, will adopt the A21 chip built on 2-nanometer process technology. The iPhone 20 launches alongside a second-generation foldable iPhone in fall 2027, following spring releases of the iPhone 18, iPhone 18e, and iPhone Air 2.
