Reports suggest Apple's upcoming foldable iPhone may feature a compact 5.3-inch outer display, smaller than current smartphones and the discontinued iPhone mini. This design contrasts with rivals who emphasize larger cover screens for regular use. The device is expected to prioritize its main experience on the unfolded inner display, with the outer screen serving secondary functions like notifications. The foldable iPhone might also incorporate a 4:3 inner display, potentially enhancing usability for reading and split-screen applications.
