The Breakthroughs Powering Samsung’s Thinnest, Most Refined Foldables

Ever since Samsung created the foldable category by unveiling the first foldable smartphone in 2019, Samsung has pursued one goal: to give users large screens in a pocket-friendly device. Years and thousands of design and engineering advancements later, Galaxy foldable devices have again not only exceeded that goal but set a new standard for mobile foldable innovation.

The Galaxy Z Fold7 and Z Flip7 are Samsung’s thinnest, lightest and most advanced foldables to date.

Pocket-friendly Proportions

Galaxy Z Flip7 slides into your pocket at just 6.5 mm thin when open and 13.7 mm when closed. An ultra-high-density circuit board makes sure there is no wasted space internally and Samsung enhanced the battery’s energy density, boosting its capacity by 300 mAh while reducing its thickness.


Meanwhile, Galaxy Z Fold7 is nearly half the thickness of the original Fold, measuring just 8.9 mm folded and 4.2 mm unfolded. This 48% reduction combined with a wider, brighter screen and a new 21:9 bar-phone aspect ratio, delivers a foldable device that is both portable and intuitive to use.

Stronger, Slimmer Hinges
 

Galaxy Z Fold7 introduces a third-generation Armor FlexHinge that is 27% thinner and 43% lighter than its predecessor. Key upgrades include:

• Thinner critical rotating and supporting elements, resulting in a hinge that is smaller in size while maintaining strength.
• New alloy components that increase yield strength by over 14% allow the hinge to better withstand repeated folding.
• Separate supporting and rotating functions add structural stability and greater design flexibility.
• A wingplate that opens wider delivers a flatter and cleaner screen for a more premium viewing experience.

Galaxy Z Flip7 features Samsung’s thinnest FlexHinge yet. It’s 29% slimmer than the hinge on Galaxy Z Flip6 yet still supports full FlexMode and day-to-day toughness.

Thinner, Stronger Displays
 

The display is a cornerstone of Galaxy Z Fold7’s hardware innovations, with a focus on greater durability while ensuring the device is lighter and thinner:   

• Reduced display thickness by more than 39% by completely reoptimizing the panel structure and introducing advanced materials.
• Titanium-based lattice replaces carbon fiber for 64% improved durability and better resistance.
• Achieved a slimmer profile by redesigning the panel layer to better absorb external stress and ensure consistent rigidity.
• Ultra Thin Glass (UTG) is 50% thicker than the UTG on Galaxy Z Fold6 for a smoother, less-visible crease and improved performance.

With Galaxy Z Flip7, Samsung maintains the Z Flip series’ iconic design but packs more power in a smaller package:
 

• A new edge-to-edge Infinity Cover Display removes the black notch to provide more content and cleaner visuals.
• The HID camera is precisely corner-mounted, keeping visuals clean and symmetrical.
• The display bezel shrinks from 3.94 mm to 1.25 mm, a 68% reduction that makes Galaxy Z Flip7 the world’s thinnest display bezel on a foldable.

Pro Cameras, Optimized for Potability
 

Galaxy Z Fold7 delivers an ultra-level camera experience, providing flagship technology in a sleek and light design.

• First 200 MP wide-angle camera in a foldable that’s made possible by a new thin actuator and a complete structural redesign.
• The camera module shrunk by 18% and ran nearly 30,000 simulations, culminating in the thinnest 200 MP camera on a foldable device that doesn’t sacrifice image quality.

On Galaxy Z Flip7, the camera module has been reengineered from the ground up, delivering flagship image quality in a slimmer housing. To achieve a thinner design while maintaining high performance, Samsung streamlined the internal structure of the entire module, incorporating a smaller actuator to ensure high-performance autofocus with less bulk.

Tougher Materials, Lighter Feel   

 

Samsung reinforced Galaxy Z Fold7’s thin profile with stronger, more advanced materials. The cover screen now features Corning® Gorilla® Glass Ceramic 2¹, making it 30% stronger² in material strength than the previous generation. Additionally, the frame and hinge cover have been upgraded to Advanced Armor Aluminum³, a material that is 10% tougher⁴ than the Armor Aluminum previous used in Galaxy Z Fold6.

The Bottom Line

Every hinge, display layer and camera component inside Galaxy Z Fold7 and Z Flip7 was redesigned for one purpose: give consumers a refined foldable that feels as effortless as any premium smartphone.

Welcome to the new era of pocket-ready power.
