Apple Prepares All-Glass Quad-Curved Design for 2027 iPhone 20 Pro Lineup

Apple is reportedly preparing a radical redesign for its 2027 smartphone lineup, with upcoming flagship devices expected to feature all-glass exteriors and the largest display dimensions in the history of the product line. Supply chain leaks indicate that the technology giant will skip the iPhone 19 designation entirely to mark the 20th anniversary of the original iPhone launch in 2007.

Apple preserves corporate narrative control by structuring its launch keynotes as standalone theatrical presentations independent of third-party rumors. Apple's iPhone Duo features a 7.6-inch folding inner display and a 5.4-inch outer cover display with 3000 nits peak brightness.

According to details shared on the Chinese social media platform Weibo by the prominent tech tipster Digital Chat Station, the forthcoming iPhone 20 Pro and Pro Max are currently undergoing testing with expanded physical screens. The standard Pro model is slated to feature a 6.41-inch display with a resolution of 2,686 by 1,236 pixels, while the larger Pro Max variant is being tested with a 6.96-inch screen operating at a resolution of 2,912 by 1,340 pixels. These specifications represent a notable upward shift from the iPhone 18 Pro and Pro Max models, which measure 6.27 inches and 6.86 inches respectively.

The Pro tier pricing structure was established in 2017 with the $999 iPhone X, with Pro Max pricing shifting to $1,199 upon dropping 128GB storage. The Indian price cut on the iPhone 16 Pro models occurred despite international dollar prices remaining unchanged.

The most striking structural change under evaluation involves a quad-curved, nearly all-glass exterior that wraps around all four sides of the handset. This layout effectively eliminates traditional borders, creating a bezel-less visual profile. The configuration matches earlier reporting from Bloomberg reporter Mark Gurman, who noted that the front and rear glass panels would curve smoothly into the sides of the devices, bridged by a metallic band in the middle.

By comparison, current flagship iterations such as the iPhone 18 Pro rely on an aluminum and ceramic glass construction with distinct side framing. Moving to a quad-curved glass architecture represents a significant departure from standard smartphone housing designs, pushing manufacturing techniques closer to a completely borderless glass enclosure.

Alongside the display expansion, the upcoming anniversary devices are projected to feature a reduced Dynamic Island cutout. Instead of the wider capsule-shaped region housing front-facing hardware on current models, the new prototypes incorporate a much smaller punch-hole selfie cutout.

Industry observers note that Apple continues to test various technological approaches for biometric sensor placement, including potential under-display Face ID implementations and under-panel camera technology similar to systems featured on Apple's newly introduced iPhone Duo foldable device. Final configuration choices remain subject to change as engineering trials progress ahead of the anticipated September 2027 market rollout.

Market analysts suggest that the commemorative nature of the 20th-anniversary release combined with complex manufacturing requirements for all-glass enclosures could prompt higher retail pricing. CNET Senior Reporter Abrar Al-Heeti observed that major structural redesigns frequently serve as financial drivers for consumer hardware manufacturers.

Along with the commemorative angle of the iPhone 20th anniversary, it is likely Apple could use design elements like a bigger screen and an all-glass design to hike prices, Al-Heeti said. Apple representatives have not responded to requests for comment regarding the unannounced devices, and production timelines remain unconfirmed.
