The first foldable iPhone is rumored to adopt a book-style form factor that will resemble Samsung’s Galaxy Z Fold lineup, but Apple is taking it a step further by employing higher quality materials that not only ensure the device’s increased durability, but also to eliminate, or at the very least, mitigate the display crease’s visibility. Additional details surrounding the build materials, display size, and resolution were shared by a tipster, so let us jump into these specifications immediately.

New rumor claims that Apple will stick with a titanium alloy chassis for the foldable iPhone, at least for the prototype

For the OLED panels, Samsung will likely be Apple’s exclusive supplier, with the technology giant previously reported to be shortlisting candidates back in February, with a launch assumed to happen in the second half of 2026. Digital Chat Station had previously provided the display sizes of the foldable iPhone, claiming that the outer display measures 5.49 inches, and when the device is completely unfolded, the inner side packs a 7.74-inch OLED. On Weibo, the tipster is back with more details surrounding the device.

On this occasion, he states that Apple’s unfinalized foldable flagship prototype has an inner panel size measuring 7.58 inches, with a 2,713 x 1,920 resolution, and an aspect ratio of 14.1:10. Previously, we reported that the same tipster mentioned a 4:3 aspect ratio, with the reason being that Apple wanted the software consistency to match the iPad’s. Fortunately, during a WWDC 2025 session, the Cupertino firm might have inadvertently revealed information about some new hardware, because apps in iOS 26 will no longer be letterboxed or scaled to adopt unique aspect ratios.

In short, developers can make their programs run natively on any display size, which might have prompted Apple to change the aspect ratio on the foldable iPhone prototype. We have also learned that the company has adopted a ‘more durable amorphous metal glass composite,’ with the rest of the body made of titanium alloy. Apple has been rumored to employ a liquid metal hinge that will improve durability and make the crease invisible. We will have to confirm whether the tipster is talking about the same component, but later.

As for the titanium alloy build, the California-based titan is keeping these materials exclusive to the more pricier models, and with the foldable iPhone estimated to cost between $2,000 and $2,500, it should be equipped with the best of everything. Since the official launch is expected to happen in late 2026, we recommend readers treat all of this information with a pinch of salt, and we will return with more updates. Remember that the retail version could ship with a truckload of changes, but remember to revisit this data for reference purposes.
