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

As is tradition, iFixit has torn open the latest iPhone and laid its parts bare on a table. It found some interesting details about how Apple might be hiding the crease on the Duo's folding screen and gave it a 5/10 repairability score. That might not seem particularly high, but it's the best score the […]

The top 3

  1. Mechanical causes of screen damage: iFixit's teardown suggests that the hinge's internal support system may occasionally malfunction, failing to retract properly during the folding process. This creates a localized stress point that, combined with the presence of fine particles that penetrate the hinge, leads to the 'crunching' and display damage observed by users.
  2. Design techniques for crease management: Apple utilizes a combination of mechanical and optical strategies to minimize the visible crease. Mechanically, the device employs retractable guides and a center support bar; optically, it uses specifically angled oval subpixels and a nano-texture coating to scatter light and blur the fold point.
  3. Repairability landscape: The iPhone Duo holds a provisional 5/10 repairability score, the highest among foldables, due to the accessibility of batteries and the outer display. However, the inner folding display remains a high-risk, difficult-to-repair component, driving many users to rely on AppleCare+ protection.
