iFixit teardown of iPhone Duo reveals likely causes of early screen failures

iFixit's teardown of the iPhone Duo, its most repairable foldable phone yet with a provisional 5 out of 10 score, has identified potential causes for early screen failures reported by owners. The teardown suggests a central support bar may not retract properly, or curved hinge rails could interfere with the display, potentially concentrating stress on the screen near the cable opening. These issues are linked to reports of crunching sounds and bright lines on the inner display. The hinge's intricate design, including gears and curved guides, aims to reduce display stress, while the matte nano-texture and oval-shaped subpixels help disguise the crease. Batteries use electrically releasable adhesive for easy removal, and the bezel can be removed without breaking.
