Apple reportedly testing ultra-thin flexible glass for foldable iPhone

Apple is reportedly testing a different type of flexible glass for the rumored foldable iPhone.

Digital Chat Station claims that the iPhone maker is evaluating an ultra-thin, flexible glass (UFG) panel designed to reduce the visibility of display creases. Several Chinese display makers are also said to be exploring the use of UFG.

Unlike Samsung’s foldable phones, which rely on ultra-thin glass (UTG) that gradually deforms along the hinge, UFG can distribute bending stress more uniformly across the entire panel. This approach could significantly minimise crease formation and potentially keep the display visually smooth even after long-term use.

“A nearly invisible crease” is tipped to be one of the foldable iPhone’s key differentiators, as visible creasing remains one of the biggest drawbacks of current foldable smartphones.

Although the foldable iPhone is said to reach the Prototype 1 stage in June, Apple’s evaluation of UFG at this point does not necessarily mean a production issue. Instead, it may be a final validation step as the company nails down the display technology.

Apple is also believed to be building up an inventory of key components ahead of an anticipated 2026 launch. The foldable iPhone is rumoured to feature a 5-6-inch cover display and an 8-inch foldable main display, along with a Touch ID power button, C2 modem, and “a much higher-quality hinge”.
