Apple’s foldable iPhone is facing more significant challenges than anticipated during its engineering test phase. According to a recent report by Nikkei Asia, the company has encountered more complex issues than expected, leading to potential delays in mass production.
The device was initially expected to launch later this year but may now face further setbacks. Engineers are working under pressure to resolve the problems, and component suppliers have been notified that production schedules might need to be adjusted. The latest developments raise concerns about the risk of further delays beyond the already delayed iPhone 18 Pro and iPhone 18 Pro Max.
Apple is currently undergoing critical engineering verification testing, a stage where new designs are validated before mass production begins. The company’s timeline is under pressure, with April marking a crucial period for the engineering test phase. A source familiar with the matter stated that more issues than expected have emerged, and additional time will be needed to resolve them.
Nikkei Asia cites sources within Apple and component suppliers warning of delays due to complexities in foldable development. In a worst-case scenario, first shipments could be delayed by months. The company is currently weighing two options for the device’s hinge material: liquid metal or 3D-printed titanium alloy. Ongoing pricing negotiations with manufacturing partners also pose a risk to the production schedule.
The situation highlights Apple’s need for more time to resolve engineering challenges and make necessary adjustments. With the current timeline already pushed back, it remains uncertain when the foldable iPhone will finally hit the market, potentially in early 2027.
