Samsung patents dual-fold smartphone with S Pen slot

Samsung is taking foldable smartphone technology to the next level. A tipster has revealed that the company could soon be developing a double-folding smartphone, meaning that it folds and unfolds in two directions.

According to the leak from LetsGoDigital, the phone will have two hinges to support its three display parts. It suggests that one part of the phone can be folded forwards, and the other backwards, to form a Z-shape. Toward the run-up to the 2021 Society for Information Display event (SID), Samsung unveiled this double foldable concept, which was termed the “S-Foldable.” The display screen was 7.2-inches, exactly the same length as the Galaxy Z Fold 3’s screen.

There is also documentation for some technology regarding Samsung’s famed S Pen. In July 2021, Samsung Electronics filed a patent with the World Intellectual Property Office about this double foldable and its S Pen. Now, 66 pages of documentation detailing this patent has been unveiled.

The documentation revealed that when the device is folded, it resembles the shape of a regular phone, except much thicker. The right-sided display in the unfolded position will form the front display, and the back of this display will have an attached slot for accommodating the S Pen. The S Pen will be magnetically held in place, ensuring that it’s in the right position while charging.

Samsung has also received a patent for a slideable smartphone, though we know less about that device. It’s also currently unclear if the dual-folding technology could be used in the upcoming Galaxy Z Fold 4, which will likely land by August 2022. While this may elevate the price of already expensive foldables such as the Z Fold 3, it could turn out to be a one-of-a-kind premium flagship product.

Samsung Galaxy S26: what we want to see
The screen on the Samsung Galaxy S25 Ultra.

It’s been less than five months since Samsung revealed the Galaxy S25 series, which includes the regular model, Galaxy S25 Plus, and flagship Galaxy S25 Ultra. While much of the attention now focuses on the incoming Galaxy S25 Edge, we’re beginning to understand better what to expect from Samsung’s Galaxy S26 lineup. At a minimum, we’re starting to outline what we’d like to see in the 2026 phones, which should launch in January.

Will the lineup once again feature three models, or will a Galaxy S26 Edge be revealed at the same time? Will we finally see massive design changes to Samsung’s most popular phone series, or should we expect more of the same?

The Galaxy S25 doesn’t look like the success Samsung will have wanted
The Samsung Galaxy S25 Ultra.

Samsung leads Apple in smartphone shipment market share, according to data from Counterpoint Research, and while this may appear good news for the brand, a deeper examination into two very different strategies indicates Samsung may not be happy with the situation at all. For the first three months of 2025, Samsung controlled 20% of the global smartphone market by device shipments, followed by Apple with 19%. This is “sell in” data, meaning devices purchased from the manufacturer by distributors. It is a considerable change over the data from the last three months of 2024, where Apple led with 23% of the market followed by Samsung with 16%.

This is crucial to understanding why Samsung may be looking at the latest figures, which on the outside appear positive, with concern. At the end of 2024 Apple would have been riding high on the release of the iPhone 16 series, while Samsung would have been far removed from the Galaxy S24 series and the Galaxy Z Fold 6 and Galaxy Z Flip 6’s release. It makes sense for Apple to command a higher market share right after the release of its flagship devices for the year.
