Apple Inc. has commenced early prototyping of its first foldable iPhone, beginning the initial P1 phase in June 2025, according to supply chain sources cited by DigiTimes. The company aims to complete prototype testing by late 2025 and plans to launch the foldable device in the second half of 2026, potentially as part of the iPhone 18 lineup. The foldable iPhone is expected to feature a book-style design with OLED displays, including an approximately 7.8-inch inner screen and a 5.5-inch outer screen, along with quad cameras and Touch ID. Samsung Display is reportedly supplying the foldable screens, reinforcing the collaboration between Apple and Samsung. JPMorgan projects the device will debut in September 2026, with a price around $1,999 and anticipates the foldable iPhone could create a $65 billion market opportunity. Meanwhile, Apple has paused its foldable iPad project due to higher production costs and weaker demand. The development of iOS 27 is reportedly focused on revamping the user interface to accommodate the foldable iPhone's form factor. Industry analysts note that Apple is entering the foldable smartphone market later than competitors like Samsung, which has released seven generations of foldable devices, but the new iPhone is expected to be a strong contender.
