iPhone Fold Hinge Noise May Delay Launch by a Month

Apple is moving ahead with production of its first foldable phone. Samsung Display has received approval to begin making screens for the iPhone Fold, with an initial order of roughly 3 million units. A September launch is under discussion, though a noisy 3D-printed hinge could push the timeline back by 15 to 30 days, according to Korean media reports.

Samsung Display will be the sole panel supplier for the iPhone Fold under a three-year exclusive deal, The Elec and ET News reported. The screens use Samsung's M16 OLED material and CoE (Color Filter on Encapsulation) technology, which makes them thinner and up to 37% more efficient. That efficiency matters for a device running two displays on a single lithium-ion battery. Apple is not adopting silicon-carbon batteries for this first generation, sticking with proven technology.

The 3 million unit order is a statement of intent. Samsung's total production target for the entire Galaxy Z Fold 8 lineup – the Ultra, Wide, and Flip 8 combined – is 5 to 6 million units. Apple's first foldable alone matches the high end of that range. For Samsung Display, the deal locks in a high-volume customer for its most advanced foldable panels.

The screen is ready. The hinge is not. Apple's iPhone Fold uses a 3D-printed hinge module that generates unwanted noise after assembly, The Elec reported. That issue is expected to delay production by roughly two weeks to a month.

"Apple is having difficulty stabilizing the production of hinge modules for its first foldable phone," one industry official told The Elec. "There are no issues with Samsung Display. The launch schedule depends on the readiness of Apple's set components, particularly the hinges."

The hinge is a moving part in a device that must fold thousands of times without failure. Samsung went through similar growing pains with its early Galaxy Fold hinges. Apple's first-generation product carries that same execution risk. The company is taking a cautious approach overall – the initial order is modest by Apple's standards, and it is not rushing into unproven battery chemistry.

For investors tracking Apple (AAPL), the hinge issue is a near-term risk to the launch window. A delay into October would push revenue from the device into the December quarter, which could affect fiscal 2025 guidance. The bigger story is the supply chain win for Samsung Display. The exclusive three-year deal signals that Apple sees foldable displays as a long-term category, not a one-off experiment.

The foldable phone market is still small. Samsung dominates with its Galaxy Z series, and Chinese brands like Huawei and Oppo are gaining. Apple's entry with a 3 million unit first run would roughly double the premium foldable segment overnight. The hinge problem will be resolved or it won't. Reviewers will test the device in the coming months. The production delay, if it holds, moves the launch from September to October.
