Apple’s first foldable iPhone may be moving closer to mass production after reportedly clearing one of its biggest engineering challenges: the hinge.
The long-rumored iPhone Fold has been surrounded by supply chain chatter for months, with most signs suggesting that Apple is preparing a premium foldable device designed to compete at the highest end of the smartphone market. While display production appeared to be on track, the hinge was believed to be the most difficult part of the project, especially because Apple is reportedly using a complex 3D-printed liquid metal design.
According to a recent industry report, trial production for the iPhone Fold began in April, and the results were strong enough for Apple to move toward mass production as early as July. If accurate, this would keep the foldable iPhone on schedule for a potential September launch window alongside Apple’s next flagship lineup.
The hinge had reportedly caused concerns during durability testing. After millions of folding and unfolding cycles, some units were said to produce unwanted rattling or noise. In foldable smartphones, the hinge is not just a mechanical part; it defines the feel of the device, affects long-term durability, and plays a major role in how visible the screen crease becomes.
Apple is believed to be focusing heavily on reducing the crease as much as possible. That goal may explain why the company is using a different hinge approach from many existing foldable phones. A smoother, quieter, and more durable hinge would help Apple position the iPhone Fold as a truly premium device rather than a first-generation experiment.
The report also claims that some assembly tolerances were higher than expected, which may have contributed to early production defects. However, many of those issues have now reportedly been improved, giving Apple more confidence as it prepares for larger-scale manufacturing.
The display side of the project appears to be more stable. Samsung is reportedly preparing to begin mass production of an advanced M16 OLED panel for the device. Around 3 million OLED displays are expected to be secured for the initial production batch, suggesting that Apple may be taking a cautious approach with availability at launch.
That would not be unusual for a new product category. Foldable phones are still more expensive and more complicated to manufacture than traditional smartphones, and Apple will likely want to carefully manage supply, quality control, and consumer demand.
If the latest production timeline holds, the iPhone Fold could launch alongside the iPhone 18 Pro and iPhone 18 Pro Max. That would mark one of Apple’s biggest hardware expansions in years, giving the company a direct entry into the foldable smartphone market after years of watching competitors test the category.
A successful iPhone Fold launch would depend on more than just the novelty of a folding display. Apple will need to deliver strong durability, excellent battery life, a refined software experience, and a hinge that feels reliable over years of daily use. The reported progress on the hinge suggests that Apple may have solved one of the most important pieces of that puzzle.
For now, the iPhone Fold remains unconfirmed by Apple. But if mass production begins in July as reported, the company’s first foldable iPhone may be much closer than ever before.
