The S Pen Returns: Samsung’s Tri-Fold Patent Reveals a Genius “Flex G” Stylus Sanctuary

Since the cessation of S Pen support in the Galaxy Z Fold7, persistent rumors have suggested that Samsung intends to reintegrate this functionality into its foldable lineage. Recently surfaced design patents indicate that Samsung envisions a tri-fold device—employing the Flex G architecture—that ingeniously accommodates the stylus by marginally reducing the width of the innermost display panel, thereby creating a dedicated sanctuary for the S Pen.

While this patent may represent a conceptual exploration rather than a definitive product roadmap, market conjecture strongly suggests that Samsung is committed to reintroducing the S Pen while simultaneously developing a successor to the Galaxy Z TriFold. The patent describes a storage concept wherein the innermost segment of the Flex G display is slightly recalibrated to carve out space for the S Pen, allowing users to nestle the stylus directly into the void created when the device is fully retracted.

To ensure the stylus remains secure, the design employs a magnetic attachment system to prevent accidental slippage. Furthermore, while docked, the S Pen can transmit its current battery status, engage in wireless charging, and confirm its proper alignment within the housing.

The primary advantage of this configuration lies in the effortless portability of the S Pen within a tri-fold form factor. However, this may necessitate minor compromises, such as a slight reduction in usable screen real estate, an asymmetrical folding profile, or a subtle shift in the device’s center of gravity—trade-offs that are likely deemed acceptable given the utility of the stylus. Moreover, this approach bypasses the need for a thicker chassis to house the S Pen internally, potentially facilitating a significantly slimmer profile for the next Galaxy Z TriFold.

These patent filings clarify Samsung’s strategic positioning for its tri-fold hardware: it is not merely a foldable telephone, but a pocketable Galaxy Tab. As a productivity instrument of tablet-grade caliber, the seamless integration of the S Pen is a non-negotiable element of the core experience. Historically, Samsung struggled to incorporate the S Pen within the Galaxy Z Fold series due to thickness constraints, necessitating cumbersome external cases. This frustration culminated in the controversial removal of S Pen support in the Galaxy Z Fold7 and Galaxy Z TriFold—a decision reportedly based on data suggesting infrequent usage, much to the chagrin of loyal enthusiasts.

By “squeezing” space for the S Pen out of the display width in a more technically demanding tri-fold design, Samsung aims to bolster its competitive edge against the influx of ultra-thin foldable devices from Chinese manufacturers. This move seeks to leverage Samsung’s long-standing stylus expertise while simultaneously rehabilitating its image, countering the perception that the company lacked the engineering prowess to achieve a svelte chassis without sacrificing its most iconic productivity feature.
