> Samsung publishes a fold rating for the Z Fold 8. Apple publishes none for the Duo, and describes the screen instead.

One of the FAQs on the [iPhone Duo](https://idevice.com/phones/iphone-fold/roadmap) product page is about the crease, and Apple's answer describes the display rather than answering the question. The inner screen is flat and smooth, it says, with a nano-texture finish and optically clear adhesives that let the layers glide as it folds. The press release goes a step further and says the finish minimizes crease visibility, which is a statement about how much you see rather than about whether it is there. MacRumors reported that neither the FAQ nor the [press release carries a fold cycle count](https://www.macrumors.com/2026/09/09/iphone-duo-crease/).

Samsung does publish that number. The Galaxy Z Fold 8, which is roughly the same shape, is rated for 500,000 folds. What Apple offers instead is a hinge with more than 100 components and support ribs and a titanium panel under the display. On size, the Duo lands two records at once. It is [Apple's thinnest iPhone at 5.2mm unfolded](https://www.macrumors.com/2026/09/09/iphone-duo-thinnest-iphone/), 0.4mm under the [iPhone Air](https://idevice.com/phones/iphone-air/roadmap), and its heaviest ever at 254 grams. Folded, it is 11.3mm. Pre-orders start October 16 and it ships October 23.
