Overview
- Supply‑chain sources reported final assembly yields for the iPhone Duo were just above 60% as of Sept. 17, meaning roughly four in ten units fail inspection during current production runs.
- Manufacturing trouble is not limited to final assembly because Samsung Display’s foldable OLED panels and several hinge components have shown low yields and delayed deliveries.
- Apple’s hinge design includes more than 100 parts and the company tested liquid metal for some pieces before changing course, which has added complexity that requires repeated equipment and process adjustments at Foxconn.
- Contractors say that under Apple’s current quality standards the line may need six months to a year to reach mature yields, and one manufacturer reportedly asked Apple to choose between prioritizing yield or increasing output.
- Apple is keeping its Oct. 16 preorder and Oct. 23 on‑sale dates, but the company’s reported 2026 stocking target of about 6–8 million units implies constrained availability and could make the Duo a limited, high‑end halo product at launch.
