According to Forbes, Samsung’s ultra-slim Galaxy S26 Edge may be cancelled entirely following disappointing sales, with multiple leaks from SamMobile, NewsPim, and leaker Ice Universe indicating the device won’t replace the Galaxy S26 Plus. The sales problems first emerged in June 2025 when Samsung began aggressive price cuts on the Galaxy S25 Edge, which measured just 5.2mm thick compared to the Galaxy S25 Ultra’s 8.2mm thickness. The Edge line appears to have served as a testbed for new design methods including miniaturized internal components, a new motherboard design, and a 10% thinner 200MP camera achieved through structural optimization of autofocus and optical image stabilization. The technology developed for the Edge has already found success in the Galaxy Z Fold 7, which reportedly broke Samsung’s European sales records. This strategic retreat from the Edge brand doesn’t mean the end for Samsung’s ultra-thin ambitions.

The Strategic Testbed Approach
Samsung has a long history of using limited-run devices to test radical technologies before mainstream implementation. The original Galaxy Note Edge in 2014 pioneered curved displays that later became standard across the Galaxy S series. What makes the S25 Edge different is that it tested manufacturing processes and component integration rather than just user-facing features. The new mounting system allowing parts to be placed closer together represents fundamental engineering innovation that can be scaled across multiple product lines. This approach allows Samsung to validate production techniques without committing to mass-market volumes, effectively treating the Edge as an R&D investment rather than a pure revenue driver.
The Technical Breakthroughs Explained
The engineering achievements behind the Edge series are more significant than the sales numbers suggest. The structural optimization of autofocus and optical image stabilization represents a major advancement in camera module design. Traditional OIS systems require physical space for movement, which Samsung has apparently minimized through what appears to be a combination of smaller actuators and smarter movement algorithms. The two-layer housing that reduced sensor height could become industry-standard for high-resolution cameras in constrained spaces. More importantly, the heat management structure redesign addresses one of the biggest challenges in thin devices: thermal dissipation without bulk. These innovations aren’t just about making phones thinner—they’re about creating more efficient internal layouts that could eventually allow for larger batteries or additional components in the same footprint.
Market Timing and Consumer Perception
The failure of ultra-thin phones in 2025 reflects shifting consumer priorities rather than engineering limitations. After years of battery life anxiety, consumers have demonstrated they prefer devices that can last through heavy usage over extreme thinness. Apple’s rumored iPhone Air reportedly faced similar market resistance, suggesting this isn’t a Samsung-specific issue but rather an industry-wide miscalculation. The timing was particularly challenging given that Fold 7 sales success shows consumers are willing to embrace innovative form factors when they offer clear functional benefits. The market appears to be saying that thinness for thinness’ sake isn’t compelling, but thinness that enables new capabilities—like folding displays—is worth premium pricing.
Future Implications and Strategic Direction
The most telling aspect of this development is where the Edge technology is appearing next. The fact that Samsung prioritized implementing these slim innovations in the Fold 7 rather than waiting for the S26 series indicates the company sees foldables as the primary beneficiary. Looking forward, the combination of this thin chassis design with next-generation carbon-silicon battery technology could create devices that are both slimmer and longer-lasting—addressing the core consumer complaint about ultra-thin devices. Samsung’s challenge will be marketing these innovations as battery life enhancements rather than thinness achievements. The company may also leverage these component miniaturization techniques to create more compact versions of its successful foldable lineup, potentially addressing the current bulk concerns with devices like the Z Fold series.
Competitive Landscape Shifts
Samsung’s experience with the Edge series reflects broader industry dynamics where Chinese manufacturers like Xiaomi and Oppo have also experimented with ultra-thin concepts. The difference is that Samsung appears to be extracting maximum R&D value from what would otherwise be a commercial failure. By treating the Edge as a technology demonstrator rather than a failed product line, Samsung can maintain its innovation leadership position while avoiding the brand damage of continuing an unpopular product. This approach also allows them to counter Chinese competitors who often lead on thinness metrics—Samsung can now claim to have developed the technology while making the strategic decision not to pursue it as a primary selling point.
The Real Legacy of the Edge Experiment
Ultimately, the Galaxy S25 Edge may be remembered not for its sales performance but for proving that component miniaturization has reached a point where thickness is no longer the limiting factor in smartphone design. The 3mm difference between the Edge and Ultra models represents what’s possible with current technology, but consumer preferences have clearly shifted toward other priorities. Samsung’s wisdom lies in recognizing this shift quickly and redirecting the technological fruits of the Edge program toward more promising product categories. The true success of the Edge experiment will be measured by how effectively these slim innovations enhance future devices across Samsung’s portfolio, particularly in the growing foldable segment where internal space remains at a premium.
