Samsung has already mastered book-style and clamshell designs and is currently working on several foldable and rollable concepts. Now, a new patent reveals the company’s wildest idea yet: a quad-fold device with three hinges and four panels, pushing the boundaries of foldable tech.

The patent is titled “ELECTRONIC DEVICE INCLUDING BENDABLE DISPLAY

This patent showcases a device with four horizontal panels linked by three hinges, all under a single foldable screen. Accompanying drawings hint at a quad-fold smartphone—Samsung’s boldest concept to date. It’s early days, though; this could be a rough draft, subject to tweaks, or even a strategic patent grab to lock down the idea for a future when the technology and market demand align.

The filing also details a tri-fold phone—it includes three panels, two hinges, with a USB-C port and triple-camera setup. It looks polished and is possibly tied to the dual-hinge tease from Galaxy Unpacked 2025. While this tri-fold feels closer to reality, the quad-fold’s ambition steals the spotlight.

Samsung’s foldable journey started over six years ago, and this patent cements its lead over rivals like Apple, which has yet to enter the foldable space. The South Korean giant’s relentless innovation on the foldable form factor—from the original Galaxy Z Fold to this quad-fold concept—keeps it ahead of its competition.

Nonetheless, it’s worth mentioning that neither the tri-fold nor the quad-fold device have a confirmed launch date, and the latter one might stay a concept for a couple of years before it sees the light of day. But two different variants of the tri-fold were recently been spotted on the GSMA database with model number SM-F9680 (likely Chinese version) and SM-F968N (possibly the South Korean variant), suggesting the availability will be limited to these two countries.
