The Stylus Reborn: A Retro Tribute or a New Solution for the AI Era?

On March 9, 2026, OPPO officially revealed a core selling point of its Find N6: a foldable screen with a nearly invisible crease, accompanied by an "AI Stylus." In an era where smartphones are trying to eliminate even physical buttons, OPPO's decision to feature a stylus has left many long-time users feeling a sense of déjà vu.

Looking back at the evolution of the mobile stylus, from the plastic sticks of the Palm era's resistive screens to the S Pen of Samsung's Galaxy Note series, and now to the Find N6's AI Stylus, mobile interaction seems to have come full circle.

Undeniably, for the past 20 years, fingers have proven far more convenient than a stylus. However, as foldable screens push towards the 8-inch mark and blur the lines with tablets, it's time to give the stylus another chance, at least in the large foldable category. The reason is simple: large foldables aim for ultimate productivity, and the inherent imprecision of touch input has always been the biggest obstacle on this path.

Samsung Gives Up, OPPO Follows Through: What's So Hard About Pairing a Stylus with a Foldable?

Although OPPO aims to bring back the "glory of the stylus" with the Find N6, it isn't the first brand to pair one with a foldable phone. Starting with the Galaxy Z Fold3 5G, the stylus specialist Samsung adapted the S Pen for every generation of its large foldable, a practice it only abandoned with the Galaxy Z Fold7 in 2025. Due to the complex internal structure of foldable phones, these styluses could never be stored inside the device like on the S Ultra series, requiring users to carry the separately sold S Pen in a specially designed case.

The fact that even Samsung, with its deep partnership with Wacom, gave up on the stylus for its latest foldable makes OPPO's persistence all the more noteworthy. So, what makes this seemingly logical pairing so difficult? The biggest challenge is the strength of the UTG (Ultra-Thin Glass) and its protective film. To be flexible, the inner screen's cover glass must be incredibly thin and soft, making it far less durable than the glass on a standard smartphone. Repeated pressure from a stylus tip can lead to significant scratches over time, a likely reason for Samsung's decision to discontinue S Pen support. OPPO claims its Find N6 uses a new "Sky Dome Memory Glass" that is three times more rigid than traditional flexible glass, clearing the first major hurdle.

Beyond screen hardness, the flatness of the hinge also significantly impacts the stylus experience. If the support structure under the hinge isn't strong enough, writing across the crease can feel uneven and even damage the hinge mechanism. Finally, there's the cost. Supporting a stylus requires an additional digitizer layer beneath the flexible display, which adds thickness and significantly increases the Bill of Materials (BOM) cost. In the increasingly price-competitive foldable market of 2026, most manufacturers can't justify sacrificing profit margins for a niche accessory, which is why OPPO remains the sole champion of this feature.

The Stylus Will Accelerate the Shift from "Consuming Content" to "Creating Content"

Given all these challenges, why does OPPO insist on pairing a stylus with its foldable? The reasons are twofold: to address the lack of precise interaction on large screens and to serve the new era of mobile AI. Large foldables are built for multitasking with multiple windows, but tapping on small menu items with a finger often results in errors, limiting their professional utility. The stylus, in its interaction logic, functions as a precise cursor. Furthermore, in the AI-driven landscape of 2026, the stylus's purpose has evolved. A common complaint was that most users lacked the artistic skill to make good use of a stylus. However, in the age of AIGC (AI-Generated Content), even a rough sketch, when combined with a powerful AI, can be transformed into a polished piece of art. This innovation removes the psychological barrier for average users, enabling them to transition from simply consuming content to actively creating it on their foldable device.

Cross-Device Ecosystem Interaction is the Future, Is the Stylus Category's Ceiling Still Rising?

The potential of the OPPO Find N6's "AI Stylus" likely won't be confined to the phone itself. ColorOS has already achieved deep integration between its foldable phones and Macs, but controlling a Mac interface through a mirrored window with a finger is a clumsy experience. The addition of the AI Stylus effectively gives the Find N6 a portable mouse, making remote Mac control a truly viable function. More broadly, the stylus can become a universal input device within the OPPO hardware ecosystem: for quick edits on the Find N6, detailed artwork on an OPPO Pad, or even as a physical controller for future OPPO glasses. This is the true boundary of the AI Stylus's capabilities. Therefore, reintroducing the stylus is not a step backward. For too long, foldable phones were marketed simply as "large-screen phones" without developing unique use cases. Only by adding the AI Stylus to fill the interaction gap can the foldable truly be called a "productivity tool."
