Samsung has consistently been at the forefront of foldable smartphone innovation, particularly with its Galaxy Z Fold and Galaxy Z Flip series. The latest addition to this lineup, the Galaxy Z Fold 6 Special Edition, has been introduced exclusively in South Korea and is celebrated for its exceptionally slim design. However, this achievement came at a cost. To reduce the device’s thickness, Samsung decided to remove the digitizer, a component essential for S Pen functionality. According to a report by The Elec, Samsung is working on a groundbreaking technology that would allow future foldable devices to support the S Pen without the need for a digitizer. This development could mark a significant step forward in foldable smartphone technology.
The digitizer, a flexible circuit board embedded in the display, is responsible for detecting the S Pen’s position. By eliminating this component, Samsung managed to reduce the thickness of the Galaxy Z Fold 6 Special Edition by 0.6 millimeters, creating a sleeker design. While this innovation enhanced the device’s portability and aesthetic appeal, it came at the expense of one of its most valued features. In response, Samsung has reportedly partnered with an industry expert to develop a new method for recognizing the S Pen without relying on a digitizer. If successful, this technology could redefine how stylus functionality is integrated into foldable devices. However, there is no clear indication whether it will be ready for the next generation of foldable phones, which are expected to launch in the second half of 2025.
In addition to exploring new ways to incorporate the S Pen, Samsung is investigating the use of glass backplates for its future foldable phones. Glass offers several advantages over the materials currently used in foldable device hinges. It is lighter, potentially more cost-effective, and can reduce the number of moving parts within the hinge mechanism, making devices more durable and reliable. Despite these potential benefits, the adoption of glass backplates presents significant challenges. Foldable smartphones endure continuous stress from repeated folding and unfolding, which necessitates glass components that can withstand such wear and tear. Industry experts have noted that this technology is still in the developmental stage, and mass production is unlikely to begin before 2026.
Another reason for Samsung’s interest in glass backplates is its strategic intent to reduce dependence on imported materials such as titanium, which is frequently sourced from China. By shifting to glass, Samsung could mitigate supply chain vulnerabilities and lower production costs, further strengthening its position in the competitive foldable smartphone market.
Samsung’s ongoing innovations underscore its ambition to remain a leader in this space. The development of a thinner Galaxy Z Fold with S Pen functionality and durable glass backplates could set new standards for foldable devices. Users who rely on the S Pen for precision tasks, such as professionals and creatives, are likely to find these advancements particularly appealing. Additionally, the introduction of glass backplates could enhance the aesthetic appeal of foldable devices while addressing practical concerns such as cost and durability.
Looking forward, Samsung’s efforts to innovate in foldable technology promise an exciting future for the smartphone market. By 2026, consumers could see devices that blend advanced functionality, superior durability, and elegant design. While challenges remain, Samsung’s dedication to pushing the boundaries of mobile technology ensures it will continue to lead the industry. These advancements signal not only a brighter future for foldable devices but also reinforce Samsung’s reputation as a pioneer in mobile innovation.
