Tri-fold phone concept is the device we didn’t know we wanted

Over the last five years since Samsung and Motorola launched their first commercially available foldable device, dozens of brands have jumped and released their folding phones. With saturation in the segment, brands are now looking to stand out with tri- and multi-fold devices, especially after Huawei launched the unimaginably thin triple-folding phone. While the usual intent with a tri-fold is to expand the phone to a foldable-like footprint, one brand is taking the opposite route and using it to make the phone more compact.

Infinix, a phone brand that’s huge in Asia, Africa, and parts of Eastern Europe, just teased a concept of a tri-fold phone that folds down to a tiny palm-sized layout. Instead of a book-style foldable, Infinix is choosing dimensions similar to a flip phone. But instead of folding twice, this one folds thrice, for a minimal layout.

In its press announcement, Infinix shares examples of use cases, where it says the phone can be mounted on bikes or gym equipment or even clipped to your pocket or a backpack’s strap, like a tiny action camera. Infinix also says it can be partially unfolded for hands-free calling and watching content, and further adds the device is built for “single-handed use” and blurs the “lines between a smartphone and an all-in-one tech companion.”

Like any flip phone, there are screens both inside and out. The concept phone uses two hinges, one of which is likely to move freely with 360-degree rotation along the bottom third. This also makes the bottom hinge thicker, and Infinix appears to have used that as an opportunity to make that section of the screen usable with distinct elements — something like the edge panels on the Samsung Galaxy Note Edge.

Of course, these are digital renders, and Infinix calls it “a visionary glimpse into the future,” suggesting this phone will likely not have a commercial release. However, it does plan to showcase the concept at Mobile World Congress (MWC) 2025 next week. Whether that would be another digital render or a physical prototype is something we will learn shortly.

At the 2026 Android Dev Summit, Google has announced some interesting features coming to both Android XR and Android CLI. Developers can now build and test apps for smart glasses without owning the hardware, while Android's command-line tools are getting upgrades that help AI coding agents test applications and identify performance problems. Both announcements could eventually mean better apps for both Android and extended reality hardware users.

Google updated its adaptive Compose skill to help developers adapt existing Android apps for laptops, foldable phones, tablets, and other form factors, including the upcoming Googlebook platform. The goal of this update is to help AI coding agents customize apps for different screen sizes and input methods without developers having to maintain separate codebases for different devices.

The new skill goes beyond responsive layouts, adding support for desktop-focused features and foldable-specific interface adjustments. Google is also signaling that adaptive app experiences will be more prominent on Google Play, with the company planning to pay more attention to how apps and games perform on foldable devices next year.
