GoKawiilWhy foldable phones already ship with a built-in inner-screen protector
Foldable phones like Samsung's Galaxy Z Fold8 and Apple's new iPhone Duo include a factory-installed protector on their flexible inner displays, since the screens use layered flexible material rather than rigid glass. Apple's version adds a nano-texture coating that creates a matte finish and reduces crease visibility. Both companies warn against removing or replacing this protector yourself, offering official repair channels instead.
