iPhone Duo
Apple's first book-style foldable smartphone, featuring a dual-screen design with both an inner and outer display. The device runs iOS and is positioned in the premium foldable smartphone market segment.
Core Facts
The iPhone Duo was released later than the foldable smartphones from the Android camp.
Based on official product images, the iPhone Duo adopts a dual independent display folding design rather than a single flexible OLED screen folded in half.
The iPhone Duo's inner display uses a "nano-texture" process, making the crease almost invisible.
