IFixit’s look inside the iPhone Duo may explain those broken screens and hinges

iFixit’s teardown of the iPhone Duo has revealed design choices that may explain both its display crease and reports of broken screens and hinges. The repair site gave the folding iPhone a 5/10 repairability score, the best it has awarded to any foldable so far. That score remains modest, underscoring how difficult folding phones are to service.
Inside, iFixit found that the internal screen uses a matte nano-texture cover. The layer improves readability in bright sunlight and helps hide the crease by scattering reflections. Under a microscope, iFixit also observed oval-shaped subpixels arranged at different angles, which it believes reduce artifacts and further mask the center crease.
The nano-texture outer layer can be replaced relatively easily without swapping the OLED panel beneath it. Repairing the display itself remains an expensive and difficult task, as with other foldables. Dust entered the USB-C port, speaker grills, and hinge, producing a crunchy feel.
Still, less glow dust penetrated the iPhone Duo than Samsung’s Z Fold8 or Google’s Pixel 11 Pro Fold. iFixit suspects the hinge’s complexity may be linked to damage reports. Part of the hinge may sometimes fail to descend properly.
An accordion cable passes over that area, close to the battery edge, potentially concentrating pressure. That could contribute to the audible crack some users reported and to broken screens. Apple did not immediately respond to a request for comment.
The findings suggest the Duo’s crease-hiding engineering may carry durability tradeoffs. iFixit’s score indicates foldable repairability is improving, but only incrementally. Future foldables will need simpler hinges and display assemblies to reduce repair costs and failures.
