Overview
- Hands‑on video first shared by Weibo reviewer Kang and amplified by tech tipster Ice Universe shows the inner display strip above the Duo’s hinge depresses under light finger pressure.
- Pressing that fold area can produce temporary surface wrinkles that snap back when pressure is released, a behavior seen across multiple early units tested.
- Reporters and industry observers link the pliable strip to possible use of variable‑thickness ultra‑thin glass, a design that makes the center thinner to bend while keeping the display wings thicker for strength.
- Apple has not confirmed the materials or processes used, and the company’s apparent choice of a softer, replaceable inner protective cover shifts some durability risk toward serviceability.
- The key question now is whether the flexible fold will resist permanent creasing or fatigue over months of daily use, so early customer units and repair data will determine if the invisible crease trade‑off pays off.
