Apple Investigates iPhone Duo Screen Cracks as AppleCare Offers Free Replacements

Apple is investigating iPhone Duo screen cracks after users reported damaged inner displays over the weekend, while independent repair firm iFixit examines a possible hinge defect. On Monday, the company acknowledged failures affecting a small number of devices and directed customers to AppleCare for free replacements.

Are iPhone Duo screens breaking?

iPhone Duo units have reportedly developed visible cracks and lines along the center fold shortly after use. Apple has acknowledged an inner-display issue affecting a small number of devices and advised affected owners to contact AppleCare immediately to arrange a free replacement, according to bloomberg. The mechanical cause remains unclear.

What is causing the iPhone Duo screen cracks?

Independent repair firm iFixit has launched an investigation to determine why the foldable phone's inner display is failing. The company is examining whether debris or uneven pressure inside the folding mechanism could be damaging the flexible screen panels.

Apple has declined to comment on the mechanical cause of the failures. The investigation is examining whether the phone's passport-style folding design provides sufficient internal protection against everyday wear and tear.

What did iFixit's 3D simulation reveal about the screen problems?

iFixit analyzed teardown footage, patent filings and engineering CT scans to create a 3D simulation of the smartphone's internal mechanics. Technicians compared the digital model with user reports of screen damage to investigate why mechanical stress may concentrate around the central folding hinge.

The simulation is intended to help experts assess whether the folding mechanism adequately shields the flexible display from everyday wear. However, the available findings do not establish a definitive cause for the reported cracks.

Apple has directed affected users to AppleCare to arrange free replacements. The company has not publicly identified the mechanical fault responsible for the display failures.
