Samsung Unveils Engineering Upgrades in Galaxy Z Fold7 and Z Flip7 with Major Design and Hardware Enhancements

Samsung has officially revealed the engineering breakthroughs behind its newest foldable smartphones—the Galaxy Z Fold7 and Galaxy Z Flip7—launched earlier this month. The company describes these models as the thinnest and most polished foldables it has ever produced.

Samsung’s Vision for Foldables -

Since launching its first foldable smartphone in 2019, Samsung has pursued a clear mission: to deliver expansive screen experiences in devices that remain pocket-friendly.

With the Galaxy Z Fold7 and Z Flip7, Samsung claims to have achieved new heights in design and engineering precision, pushing the foldable category forward significantly.

Key Innovations in the Galaxy Z Fold7 and Z Flip7 -

Compact and Streamlined Designs -

The Galaxy Z Flip7 boasts a thickness of just 6.5 mm when unfolded and 13.7 mm when folded. This slim profile is credited to two main enhancements:

• An ultra-high-density circuit board that minimizes wasted internal space.
• A redesigned, thinner battery that adds 300 mAh of capacity.

In comparison, the Galaxy Z Fold7 has nearly halved its folded thickness from previous models, measuring 8.9 mm when folded and 4.2 mm when open. It also offers a wider, brighter display with a new 21:9 aspect ratio for improved usability.

Thinner, Stronger Hinges -

The Fold7 features Samsung’s third-generation Armor FlexHinge, designed to be lighter and thinner by:

• Using smaller rotating parts and new alloys that increase yield strength by over 14%.
• Separating support and rotating components to enhance hinge stability.

The hinge also sports a redesigned wingplate that allows for a wider opening angle and a flatter screen surface. Meanwhile, the Galaxy Z Flip7 incorporates Samsung’s slimmest FlexHinge yet, 29% thinner than the Flip6’s, while maintaining full FlexMode functionality and daily durability.

Enhanced Display Durability and Slimness -

Samsung improved the displays on both foldables by reducing thickness and increasing strength. Specifically, the Galaxy Z Fold7’s display:

• It is over 39% thinner thanks to a new panel design.
• Replaces carbon fiber with a titanium-based lattice, improving durability by 64%.

The Ultra Thin Glass (UTG) layer is also 50% thicker than that on the Fold6, helping reduce crease visibility and strengthen the screen. The Galaxy Z Flip7’s edge-to-edge Infinity Cover Display removes the black notch and slims the bezel from 3.94 mm to just 1.25 mm—a 68% reduction—making it the narrowest bezel on any foldable screen worldwide.

Optimized Camera Hardware -

Samsung redesigned the cameras to deliver flagship quality while keeping the devices slim. The Galaxy Z Fold7 features:

• The first-ever 200 MP wide-angle camera on a foldable.
• A smaller actuator and restructured module that reduces camera size by 18% without compromising image quality.

The Galaxy Z Flip7’s camera was fully reengineered with a compact actuator for faster autofocus and high-quality photos in a slimmer form.

Upgraded Materials for Strength and Weight Savings -

To enable thinner designs, Samsung enhanced materials across the devices:

• The Fold7’s cover screen uses Corning Gorilla Glass Ceramic 21, which is 30% tougher than previous versions.
• Its frame and hinge housing employ Advanced Armor Aluminum, improving toughness by 10% compared to the Fold6.

Samsung’s Final Thoughts -

Samsung emphasizes that every major component—from hinges and displays to camera systems—was reengineered to provide a foldable smartphone experience that rivals premium flagships in smoothness and reliability. These advances result in the Galaxy Z Fold7 and Z Flip7 being thinner, lighter, and more refined without sacrificing durability or performance.

Both the Galaxy Z Fold7 and Galaxy Z Flip7 are now open for pre-order globally, including India, through online and offline retail channels.
