After spending a month with the Samsung Galaxy Z Fold 8, its closed form has emerged as its most compelling feature. Daily use has increasingly shifted to its smaller, external 5.5-inch screen, not out of convenience but because Samsung may have found a design that feels more natural for everyday tasks. The screen has a 16:10 ratio, offering more space for thumbs, better room for photos and web pages, and a more comfortable fit for horizontal videos. However, the edges of the screen are harder to reach with one hand, the keyboard quickly takes up space, and vertical videos can feel cramped. The Galaxy Z Fold 8 has helped users accept foldable smartphones without even opening them. The upcoming Apple iPhone Duo adds a new layer to this trend, as Apple is also embracing a similar "passport" format, featuring a 7.6-inch internal screen and an external display. The iPhone Duo includes a titanium frame, Ceramic Shield, IP68 certification, Apple Pencil support, an A20 Pro chip, and a Liquid Glass interface designed for multi-window use. This shows that Apple is taking this form factor seriously and adapting the user experience to match. Xiaomi is also moving in the same direction with its 18 Fold, previewed at IFA 2026, which has a 5.38-inch cover display and a 7.58-inch internal screen. This device uses a homegrown XRing O3 chip, a triple Leica module camera, and a semi-open mode, but it is currently limited to the Chinese market. Meanwhile, Motorola is preparing a model codenamed Parker, with leaks suggesting a 4.97-inch external screen, a 6.92-inch internal screen at 165 Hz, a Snapdragon 8 Gen 5 chip, 12 GB of RAM, a 5000 mAh battery, and a closed size of just 11 x 7.6 cm. A presentation is expected by the end of 2026. Huawei is pushing the concept even further by eliminating the hinge in its Pura X View, creating a device that uses this silhouette without any moving parts. Its 6.39-inch OLED display with a 16:9.5 ratio offers 114.27 cm² of screen area in a very slim 6.68 mm frame weighing just 201 grams. It also includes a large 7000 mAh battery, a Kirin 9030S processor, 12 GB of RAM, up to 1 TB of storage, and triple 50 MP cameras. It runs on Huawei's homegrown operating system, without Google services. Priced around 6000 yuan, or roughly 760 euros, it is significantly less expensive than other high-end foldables. The "passport" format is changing how people think about foldable smartphones. The appeal is no longer just about the large internal screen but also the comfort and usability when the phone is closed. Samsung shows that the shape of a screen is just as important as its size. While it's too early to say goodbye to traditional smartphones, they now have a serious competitor. The next evolution of our screens may not be to make them bigger, but to stop stretching them.
