Engineering problems stall Apple’s foldable iPhone in early test production, reports say

Apple’s foldable iPhone is supposed to be the company’s big answer to a category it has watched from the sidelines for years. The whole pitch only works if App(businesstimes.com.sg)ion, and that’s reopened the possibility that the first launch slips from late 2026 into 2027. Nikkei’s report, echoed across Reuters pickup coverage and Apple-watchers, is the first concrete sign that the schedule is no longer comfortable.

Early test production is where those problems stop being theory and start breaking real units. (businesstimes.com.sg) ### Why is a foldable iPhone so hard? A normal iPhone is a ri(businesstimes.com.sg)rease, and no hinge wobble. Every millimeter matters. If Apple is also chasing its usual standards for fit, finish, and longevity, the tolerances get brutal fast. Samsung learned this the hard way years ago.
