Apple’s long‑anticipated first foldable iPhone has run into engineering problems in the early test‑production phase that could push back mass production and initial shipments by months, Nikkei Asia reported on Monday, citing people familiar with the matter. The potential slippage threatens the company’s plan to feature the device as part of a flagship launch originally targeted for the second half of 2026.
“It’s true that more issues than expected have emerged during the early test production phase, and additional time will be needed to resolve them and make necessary adjustments,” one source told Nikkei, according to the report. The news represents the latest sign of the technical and manufacturing challenges Apple faces as it attempts to enter the foldable smartphone category dominated so far by rivals such as Samsung.
Reuters could not independently verify Nikkei’s reporting, and Apple did not immediately respond to a request for comment outside regular U.S. business hours. Nikkei had previously reported in January that Apple planned to prioritise a foldable model along with two non‑folding iPhones that would feature upgraded cameras and larger displays for a major product push in the back half of 2026.
The problems are said to have emerged during engineering validation and early test runs, a phase when prototypes are converted into pre‑production units to validate manufacturing processes, materials and assembly. Issues discovered at that stage often require design tweaks, tooling changes or supplier adjustments — any of which can extend timelines by weeks or months depending on complexity and component lead times.
For Apple, a delay carries strategic as well as logistical implications. A foldable iPhone is widely viewed as a move to expand the company’s premium hardware lineup and to compete more directly in a market where foldables are increasingly central to flagship offerings. Pushing a launch beyond a planned 2026 window could cede momentum to competitors and affect forecasts for Apple’s device revenue that investors and supply‑chain partners are closely watching.
Supply chain considerations also complicate recovery from setbacks. Contract manufacturers and component suppliers must coordinate changes across multiple facilities and suppliers, and lead times for specialised parts such as flexible displays or hinge assemblies can be long. That makes late‑stage engineering changes particularly costly and time‑consuming for any company, Apple included.
Apple has in the past adjusted product schedules when development hurdles emerged; whether the current issues will translate into a significant postponement remains unclear. If the problems are resolved quickly, delays could be limited; if not, the report suggests Apple may need to push the first shipments into 2027, altering the timeline for what would be one of its most consequential device launches in years.
