Ultra-Slim Breakthrough: Galaxy Z Fold7 Becomes Thinnest Foldable with Refined Hinge and Display

On July 21, Samsung unveiled the engineering behind the Galaxy Z Fold7 in a detailed blog post, showing how an ultra-thin hinge, lightweight chassis, and streamlined display panels combine to make it the thinnest foldable phone the company has ever built.

I. Hinge Innovation: Next-Gen FlexHinge

  • 27% Thinner, 43% Lighter
    The new FlexHinge is 27% slimmer and 43% lighter than the Galaxy Z Fold6’s hinge, allowing the folded device to slim down to just 8.9 mm.
  • Enhanced Durability
    Despite its reduced size, the Fold7’s hinge passed 500,000 open/close tests, ensuring robust long-term reliability.

II. Display Slimming: Optimized Panel Structure

  • Reengineered Layers
    By using advanced flexible materials and thinner adhesive layers, the unfolded Z Fold7 measures just 4.2 mm at its slimmest point—50% thinner than the original Galaxy Fold.
  • S Pen Trade-Off
    To remove the bulky digitizer layer, the Fold7 sacrifices S Pen support, but gains a paper-thin side profile and improved one-handed grip.

III. Camera System: 200 MP Main Shooter Goes Compact

  • Slim Focus & OIS Actuators
    The camera module uses compact, light actuators for autofocus and stabilization, shrinking the module’s footprint without compromising performance.
  • High-Resolution Sensor
    Sporting a 200 MP sensor, the Fold7 delivers stunning detail while maintaining a slim camera bump.

IV. Balanced Experience: Thin Yet Tough

  1. Easy One-Hand Use
    At just 4.2 mm unfolded, the Fold7 feels more like a flat smartphone, making it easier to handle. Folded, it tucks comfortably into pockets.
  2. Rigorous Durability
    Beyond hinge tests, the Fold7 passed extreme folding, drop, and vibration trials, ensuring reliability in everyday use.


Through hinge, display, and camera innovations, the Galaxy Z Fold7 achieves record-thin dimensions without sacrificing durability. While it forgoes S Pen support, its enhanced portability and solid build deliver a next-level foldable experience for users seeking both style and substance.
