GoKawiilApple's iPhone Duo foldable reviewed: dual OLED screens, heavier build
Engadget's review of Apple's iPhone Duo foldable describes a 5.4-inch 120Hz OLED outer display with up to 3,000 nits brightness, paired with a 7.6-inch inner panel sharing the same aspect ratio and interface for a seamless transition. The inner screen uses a matte nanotexture coating to reduce glare and hide the crease, which is replaceable for $49 but can be damaged if peeled at improperly, with no on-device warning against doing so.
