iPhone Duo review: Apple's first foldable brings Touch ID and Apple Pencil

ZDNet reviewed Apple's first foldable, the iPhone Duo: a 5.4-inch cover screen and 7.6-inch inner LTPO OLED with a matte nano-texture finish and Apple Pencil support, a Grade 5 titanium frame and 254 g weight. Face ID is replaced by a side-mounted Touch ID, and many apps are still not optimized for the dual-screen design.
