Samsung Introduces the Ultra-Thin Galaxy Z Fold7: Setting a New Standard for Foldable Phones
At the latest Galaxy Unpacked event in New York, Samsung unveiled the Galaxy Z Fold7, marking a pivotal evolution in foldable smartphone technology. With a stunningly slim profile—just 8.9mm when closed and an even more impressive 4.2mm when open—this newest device has achieved a 48% reduction in thickness compared to the original Galaxy Fold. This remarkable engineering feat not only shatters previous benchmarks for foldables but also cements Samsung’s dominance in the ever-competitive smartphone landscape.
The Journey Toward Slimmer Foldables: Evolution Since 2019
Galaxy Fold (2019): The Pioneer of Foldable Smartphones
In 2019, Samsung captured the world’s attention with the release of its first foldable phone—the Galaxy Fold. With its hallmark 17.1mm thickness when closed and 7.6mm when open, the device delivered the first genuine foldable display experience and signaled the arrival of a new era in smartphone innovation. Users enjoyed the luxury of a compact form factor that could transform into a full-sized display, unlocking unprecedented versatility for productivity and entertainment.
Galaxy Z Fold2 (2020): Advanced Hinge, Enhanced Usability
Samsung followed up with the Galaxy Z Fold2, introducing the intricate Hideaway hinge. Composed of more than 60 internal components, this hinge delivered smoother, more flexible folding while reducing the closed thickness to 16.8mm and the open profile to 6.9mm. The elegant integration of the hinge mechanics allowed for a seamless and user-friendly experience, pushing the boundaries of what foldable smartphone engineering could accomplish.
Galaxy Z Fold3 (2021): Durability Meets Innovation
In 2021, the Galaxy Z Fold3 set a new gold standard for the category. Now just 16.0mm thick when closed and 6.4mm when open, it was the first in the series to support the S Pen, introducing new avenues for creativity and productivity. Featuring an IPX8 water-resistance rating, reinforced Armor Aluminum frame, and upgraded Sweeper technology to block dust intrusion, the Z Fold3 combined thinness with enhanced resilience—ensuring reliability for daily use without compromising on slim design.
Galaxy Z Fold4 (2022): Precision in Engineering, Lighter Design
Samsung’s 2022 iteration, the Galaxy Z Fold4, prioritized further reduce weight and thickness, down to 15.8mm closed and 6.3mm open. A new linear motion hinge mechanism replaced the previous gear-based system, trimming internal components and pushing the foldable's thinness further while maintaining robust performance for tech enthusiasts and professionals alike.
Galaxy Z Fold5 (2023): Flex Hinge for Seamless Folding
The Galaxy Z Fold5 introduced the innovative Flex Hinge, featuring a four-axis motion to gently arc the display when closed. This solution not only eliminated the notorious gap between halves and reduced the crease, but also achieved a more compact and polished look. The closed thickness shrank to just 13.4mm, with 6.1mm when open—bringing portability and refinement to new heights.
Galaxy Z Fold6 (2024): Peak Portability and Versatility
In 2024, the Galaxy Z Fold6 raised the bar further with an even slimmer body—measuring only 12.1mm closed and 5.6mm open. An optimized dual-rail hinge design enabled device closure at angles between 75 and 115 degrees, enhancing flexibility for both creative and business use-cases. The lighter and more compact build made all-day carry easier and suited the demands of on-the-go professionals and tech-savvy users.
Galaxy Z Fold7: The Pinnacle of Foldable Engineering
Ultra-Slim and Durable with the Latest Armor FlexHinge
The all-new Galaxy Z Fold7 is not only Samsung’s thinnest Galaxy phone ever but also a symbol of relentless R&D. With its next-generation Armor FlexHinge design, the device cleverly harnesses advanced materials to achieve exceptional durability without bulk. This newly optimized structure ensures the foldable screen remains protected during years of intensive use, addressing previous consumer concerns and setting a new benchmark for the category.
Bigger, Brighter Displays for Superior User Experience
Samsung has continued to elevate the user experience by expanding the display sizes. The outer cover display grows to 6.5 inches (164.8mm), up from the previous generation’s 6.3 inches, ensuring broader visuals even when the phone is folded. Open it up, and you’re greeted by a massive 8.0-inch (203.1mm) main display—the largest in Z Fold history—providing 11% more screen real estate for multitasking, gaming, and immersive content consumption.
Advantages and Real-World Use Cases
The relentless thinning of the Galaxy Z Fold series isn’t just an aesthetic victory; it delivers tangible benefits for daily life:
- Portability & Comfort: The ultra-thin footprint means easier storage in pockets and bags, with less weight and bulk for professionals and travelers.
- Enhanced Productivity: The larger and more accessible cover screen allows for quick interactions, while the expansive inner display unlocks PC-like multitasking, perfect for document editing, video calls, and split-screen workflows.
- Durability & Longevity: The Armor FlexHinge and reinforced materials offer peace of mind—this is a foldable designed for real-world usage without compromise.
- Versatility: Flexible hinge design supports a wide angle of operation, making the device adaptable for presentations, on-the-go creativity, or hands-free video streaming.
Comparisons and Market Impact
With each generation, Samsung’s Z Fold series has further distanced itself from the competition—not just in design thinness, but in display technology, hinge reliability, and everyday usability. In a market where foldable devices are increasingly vying for attention, the Z Fold7 reasserts Samsung’s leadership by setting unmatched standards in engineering, innovative features, and user-friendly functionality.
Conclusion: Shaping the Future of Foldable Smartphones
Samsung’s journey from the bulky first-generation Galaxy Fold to the impressively thin Galaxy Z Fold7 exemplifies relentless innovation in foldable smartphone design. Year after year, the company has curtailed thickness, expanded displays, and fortified durability while delivering meaningful improvements to user experience. As demand surges for ultra-portable, productivity-focused devices, the Z Fold7 stands out as a beacon of what’s possible—showcasing how breakthrough engineering can make foldables not just a novelty, but an essential tool for work, creativity, and daily digital life.
With continuous advances in hinge technology, display engineering, and materials science, Samsung ensures that each new Z Fold generation redefines the foldable market and keeps pushing the limits of mobile innovation.
