The iPhone Duo is launching later this month, and some of the most pressing questions about it are slowly starting to get their answers. As with all foldables, one of the major concerns is the durability of the internal display, but the foldable iPhone may have a unique trick to ensure that everything looks great longer.
iPhone Duo officially has a replaceable cover layer on the internal display
Apple was boasting about the nano-texture cover on the inner display of the iPhone Duo, and it appears there’s even more to it. In an interview with content creator Angelica Fendi, known as @angietutorials on TikTok, Apple VP of Hardware Engineering Kate Bergeron confirmed the cover layer can be removed and replaced.
The main goal of the nano-texture cover layer was to minimize the crease in the center of the inner display. However, even if this layer of the display gets damaged, users will be able to peel it off and replace it. Just like the cover layer itself, the ability to replace it is something other foldables don’t support.

How much does replacing the cover layer on the iPhone Duo display cost?

For US customers with AppleCare+ coverage for the iPhone Duo, replacing the cover layer will cost $19, according to Apple’s website. However, it is still unclear how much the same service will cost for customers who are not paying for AppleCare+.
The nano-texture finish of the foldable display on the iPhone Duo gives a matte effect and reduces glares and reflections, but it’s also meant to create a “perceptually flat” surface. During the unveiling of the foldable, Apple boasted about the structure of its internal display, saying the cover layer is 40% stiffer than other materials used in the industry.
In her interview with Angelica Fendi, Kate Bergeron reiterated this, saying one of the focuses with the display was to make sure this layer remains in good condition for as long as possible.
The matte display coating does a really nice job of, I’ll say minimizing the crease. But there’s a cover layer on top, and we’ve done a significant amount of engineering work to help that wear in as long of a manner as we can, and to make sure that you get the most out of that layer’s performance.

This move will address some of the main concerns users online have expressed about the internal display of the iPhone Duo. While some users on Reddit were focused on the colors of the matte display, others expressed concerns about the longevity of the cover layer especially on the frequent rubbing points such as the place where on-screen joysticks appear in video games. These won’t matter as much if changing the top layer is an accessible option.
Another surprise for the competition

When launching the Galaxy Z Fold 8 and Galaxy Z Fold 8 Ultra, Samsung spent some time to brag about its own Flex Titanium technology. By mixing new materials and a new design for the hinge and the overall display structure of the two foldables, the company said it has secured a less visible crease, higher image quality, and higher durability.
Due to the titanium elements in the design, the Z Fold 8 doesn’t have S Pen support, while the iPhone Duo is expected to get Apple Pencil support later this year. The Pixel 11 Pro Fold doesn’t have a stylus support either, but other foldables, such as the Motorola Razr Fold and Honor Magic V6, offer such an option.
However, no other foldable comes with a cover layer that can be peeled off in case of any issue with its look and feel. Considering the pace of innovation in the Android world, this is likely to change sooner rather than later.
A nifty trick from Apple
I am impressed by Apple’s approach to the iPhone Duo display, and the way the company is communicating its “abilities.” During last month’s keynote, Apple’s Chief Hardware Officer Johny Srouji presented the display as the technological innovation of the century.
Now, the nano-texture cover is revealed to be something closer to a glorified matte-finish screen protector. That’s not necessarily a bad thing, and I’m even more eager to see how it holds up in real-life use.
