The arrival of the iPhone Duo to Apple changes the environment of foldable devices in the market, a format that has evolved primarily toward hardware improvement: thinner hinges, lighter units, and screens that hide the crease better. These advances are necessary, but they have also accustomed users to accept problems in units that cost nearly two thousand dollars. Apple arrives late to the category and did not invent this concept, a behavior the company has repeated with other products like the HomePod or Siri’s artificial intelligence.

An iPad mini in the pocket

The concept of the new device is simple: closed, the iPhone Duo is thicker and resembles a passport, but when opened it reaches the approximate size of an iPad mini. The interior screen of 7.6 inches is organized as two side panels. Changes in the grid and desktop pages reflect consistently between both formats. Opening the phone does not mean finding another space that needs organizing separately.

The dock and side menus take advantage of the 4:3 format width. Instead of placing controls at the bottom and top, the interface uses available space on the right side due to the screen width. This decision seeks to adapt the system to the device and hands, something that should be a central piece in any foldable. This same format failed in the first Pixel Fold because Android was not well prepared for large screens at that time, while iOS does better thanks to the long app support for iPad.

The iPhone Duo multitasking offers one of the most interesting examples. With two apps open, the swipe-up gesture returns to home on one half without interrupting the other. Each side works as an independent space, allowing to switch an app while keeping the one needed on the side. In Android, the up gesture always closes both apps, but it is much more flexible when opening more than two apps.

The difference is in the details

The keyboard also responds to the format. When folding the unit partially, it splits automatically to facilitate typing. This is a necessary step due to the screen width, something that does not happen in Android, where two options are offered: a miniature keyboard for one-finger typing or the keyboard that extends across the full width. The transition between panels follows that same logic. The phone software is in complete sync with the hinge, something that in 8 years has not been worked on in Android.

The iPhone Duo uses the hinge angle to sync blur and open animations, while games and 3D apps continue execution when moving to the exterior screen or vice versa, something in Android would cause the app to restart. If a laptop-format video is being viewed, the bottom part with controls shows a reflection of the screen playing the video, as if it were glass, following the Liquid Glass design line.

These visual effects are striking and generate the feeling of keeping what is being done without restarts, interruptions, or black screens, evidencing that there is work and effort to offer a product that justifies its high price. It remains to check how much of that continuity remains with third-party apps, but knowing the app support history on iOS, developers should not take long to adapt their apps to this new format. In the end, everything seen are demos seeking to show the iPhone Duo potential, but real user routines are not limited to well-adapted apps.

Android advances and the future

Samsung deserves recognition for opening the path and developing powerful multitasking. Their tools allow taking advantage of the screen for tasks that would be uncomfortable on a conventional phone. However, adding functions does not automatically solve ergonomics or continuity between formats. Google has put special emphasis on the good use of both screens and available space, presenting contextual split screen when opening a link, exterior panel functions for photographing children, or bubble use for multitasking on large screens.

Chinese manufacturers like OPPO, Honor, and OnePlus have opted for offering increasingly lighter and thinner devices, with modern batteries that have brought the high range to a superior level. That progress also matters, because a foldable must also be comfortable to carry. But animations, the keyboard, and app management deserve as much attention as hardware advances. With its presentation alone, the iPhone Duo has demonstrated that there was room to improve much more on what was already known in these 8 years. It seemed Android was stagnant waiting for Apple’s answer in this niche.

A device with weaknesses

That attention to details also appears in the device speakers, located in opposite corners when opening the unit, allowing stereo sound in either format and any orientation while open.

The Duo is not believed to be perfect, it also has details that immediately call attention.

Apple also has commercial reasons to enter. Although foldables remain a very small niche in much of the West, China’s weight in this category converts the Duo into an important bet to compete in the high premium range. Only in China is sold almost half of the foldables sold in the rest of the world. Arriving late to the fight almost always allows Apple to improve its products, but it also forces the company to justify why they enter 8 years later.

It remains to check format comfort when closed, like a left-handed user would use it, battery life when intensively using the interior screen, temperature in difficult climates, and the freedoms multitasking on iOS can offer. We know how nice the Vision Pro looks and how disappointing they have been upon consumer arrival. The iPhone Duo puts on the table solutions the industry should have prioritized before, and will lead competition to develop better software.

But it must also demonstrate that they work and that the public remains interested in this format. Ultimately, we know for a long time that a screen can fold, but what we really want to check is that the experience is better than buying an iPhone and an iPad separately, which would cost less money.
