Apple’s upcoming foldable iPhone is reportedly facing pre-assembly yield issues in the supply chain, though a September launch alongside the iPhone 18 Pro remains on track. Some info coming from trusted tipsters seems to be giving out mixed signals, while Apple is trying to negotiate better prices from suppliers.

As previously reported, Apple’s long-awaited entry into the foldable smartphone market is reportedly hitting some speed bumps in the supply chain.

According to a new exclusive report, the first-gen foldable iPhone is currently facing mass production yield issues during the crucial pre-assembly phase. One of the trusted tipsters claims that Apple’s current production hurdles aren’t actually related to hinge reliability (an issue flagged by other insiders) but rather comes from surface-mount technology (SMT) complications.

SMT is the process by which electrical components are mounted directly onto the surface of a printed circuit board (PCB). Right now, pre-assembly yields are reportedly failing to ramp up to Apple’s strict standards.

Fresh reports add another layer of complexity to the list of recent iPhone Ultra/Fold supply chain leaksThe hinge debate: Just days ago, fellow insider “Instant Digital” reported that Apple’s custom hinge mechanism was failing high-frequency durability tests. However, it was noted the issue was unlikely to delay the release window.Timeline pressures: Earlier in April, DigiTimes reported that the project was running 1-2 months behind schedule; mass production still scheduled to kick off in JulyMoney, money, money: “Fixed Focus Digital” also previously hinted that ongoing price negotiations between Apple and its primary assembly partners were introducing friction into the production timeline.

Will Apple’s foldable iPhone Ultra be delayed?

Despite a growing list of “unusual production difficulties”, which suggest the “situation isn’t looking optimistic”, the consensus among the top analysts is that a September 2026 announcement is still on the table.

Bloomberg recently reiterated that the foldable iPhone remains on track for a September reveal alongside the iPhone 18 Pro series, though it’s worth noting that timing is never completely final until mass production ramps up.

When it does debut, the foldable iPhone is rumored to carry a price tag of at least $2,000. This is said to get you a 7.8-inch main display, a 5.5-inch external cover screen, Apple’s first 2nm SoC, the A20 Pro, a side-mounted Touch ID sensor, and a dual-camera array.
