Apple's foldable iphone hit with engineering snags, posing delay risks

Apple's highly anticipated foldable iPhone is facing a series of engineering hurdles that could derail its autumn debut alongside premium 'Ultra' devices like a touchscreen OLED MacBook Pro and camera-equipped AirPods.

Production tests reveal unexpected challenges

Nikkei Asia has reported that insiders close to the Cupertino giant confirm the issues plaguing the 'smartphone's' development phase, with sources describing the current situation as 'more problems than anticipated'.

'It's true that more issues have cropped up during the initial testing phase, and more time will be needed to resolve them and make the necessary adjustments,' one insider divulged. 'The current situation could put the mass production schedule at risk.'

April is slated as a 'crucial' month for the test phase, with the process expected to stretch into early May. 'Apple and the supply chain are working under excessive pressure, and current solutions aren't sufficient to fully address the engineering challenges. More time is needed,' another source stressed.

Each new iPhone model must navigate six stages before launch: introduction to production, engineering verification tests, development verification tests, production verification tests, pilot production, and mass production. According to Nikkei, Apple's problems are arising during the fourth phase.
