Apple said on October 26, 2026, that a small number of iPhone Duo screens are affected by an inner-display issue, days after its first foldable phone went on sale. The company advised customers experiencing display problems to contact AppleCare for a replacement.

Key Takeaways

  • The iPhone Duo went on sale on October 23, with prices starting at $1,999.
  • Apple says an out-of-warranty inner-screen repair costs $999.
  • Repair firm iFixit has proposed a possible connection to the hinge design, but the cause has not been established.

iPhone Duo screens and replacement advice

Some owners reported that their phones’ inner displays broke, showing bright horizontal lines extending from the hinge. Apple said it was aware of an issue affecting a small number of units and would replace affected devices under its AppleCare warranty.

Many reports appeared anonymously on online forums, including Reddit and X, and fake images have also circulated online. Apple did not specify how many phones were affected.

Hinge design under scrutiny

After dismantling the phone and testing its resistance to dust, repair firm iFixit theorized that the issue could be connected to the hinge design. Technician Shahram Mokhtari said many damage reports described a crunching sound as the phone was folded or unfolded.

IFixit CEO Kyle Wiens said a manufacturing variance or a grain of sand could damage the display panel protected by the hinge. Those explanations remain possibilities, not a confirmed diagnosis.

Early reviewers praised the unfolded phone for multitasking and media but noted that many apps had not been updated for its larger display. Apple said developers were rapidly updating apps for the device.
