Apple has acknowledged the iPhone Duo screen cracking issue after several owners reported damage to the foldable phone’s inner display. In a statement issued on October 26, 2026, the company said the problem affects a small number of devices. Apple is directing affected customers to AppleCare for replacements.
The response comes just days after Apple launched the iPhone Duo on October 23. Early complaints describe cracks appearing along the central hinge, sometimes accompanied by bright lines across the display. Apple has not identified the cause or announced a hardware fix.
Apple Acknowledges iPhone Duo Screen Cracking Reports
Apple confirmed the issue in a statement provided to 9to5Mac. The company said early customer feedback had been positive overall, but acknowledged problems with some inner displays.
Apple stated that it was aware of an issue affecting a small number of units. Customers experiencing display problems should contact AppleCare for a replacement. The company did not disclose how many devices were affected.
Several customers reported damage shortly after receiving their phones. Some described unusual resistance while unfolding the device. Others reported hearing a popping sound before cracks or bright horizontal lines appeared.
The complaints share a similar pattern, with damage concentrated near the center of the folding display. However, individual customer reports do not establish the defect’s overall frequency. Apple maintains that the problem affects only a small portion of devices.
iFixit Investigates Possible Hinge Problems
iFixit repair specialists examined the iPhone Duo’s construction to investigate the reported failures. Their detailed teardown revealed a complex hinge assembly designed to support the flexible screen during folding.
The mechanism uses interconnected joints, springs, and gears to control movement. It also includes supporting structures beneath the display. These components help distribute mechanical stress as the phone opens and closes.
Using teardown footage, patents, and CT scans, iFixit developed a three-dimensional model of the hinge. The researchers compared its construction with locations where owners reported screen damage.
One possible explanation involves a central support bar beneath the display. If the component fails to move as intended, it could create localized pressure during folding. However, iFixit has not confirmed that this mechanism caused the reported failures.
Other possible explanations include manufacturing variations or problems with nearby hinge components. Apple has not publicly confirmed any of these theories. The investigation therefore identifies potential mechanical vulnerabilities rather than a proven defect.
What Should Affected iPhone Duo Owners Do?
Apple advises customers experiencing inner-display problems to contact AppleCare. Affected devices may qualify for replacement under the company’s response to the reported issue.
Some customers have already received replacement phones through Apple retail stores. However, limited inventory could delay replacements in certain locations. Availability may depend on regional stock and individual service arrangements.
Owners experiencing unusual hinge resistance, display lines, or visible cracking should contact Apple Support. Apple has not issued specific handling instructions related to the reported defect. Customers should avoid attempting repairs themselves.
Replacement support does not automatically cover every form of accidental display damage. Apple will still need to assess each device and its circumstances.
Early Display Problems Raise Durability Questions
The iPhone Duo represents Apple’s first entry into the foldable smartphone market. Its flexible display and intricate hinge introduce engineering challenges conventional iPhones don’t face.
The latest reports highlight the importance of long-term durability for foldable devices. Repeated opening and closing place mechanical demands on flexible display assemblies. Manufacturers must balance thin designs, screen protection, and reliable hinge movement.
Despite the reported failures, iFixit awarded the iPhone Duo a provisional repairability score of 5 out of 10. The organization described it as the most repairable foldable smartphone it had examined. However, replacing the inner display remains difficult and expensive.
Apple’s acknowledgment establishes that some devices have experienced a genuine display problem. It does not establish a widespread failure affecting the entire product lineup.
The immediate priority is replacing affected devices and determining the cause of the damage. It remains unclear whether Apple will introduce manufacturing changes or additional service guidance. Further findings will help establish the issue’s scale and implications for iPhone Duo owners.
