Samsung’s Galaxy Unpacked event on July 9 in New York City will showcase what the company boldly calls its “thinnest, lightest, and most advanced foldable yet,” the Galaxy Z Fold 7. After years of iterative updates, Samsung’s flagship foldable undergoes a dramatic redesign, slimming down to potentially 4.1mm when unfolded (versus 5.6mm for the Fold 6) and 8.2mm when folded. This reduction, described by early hands-on reviewers as “wildly thin,” aims to make the device feel “just like your regular phone” when closed.
The Engineering Behind the Slimdown
Achieving this sleek profile required significant re-engineering. Samsung leveraged R&D breakthroughs from its ultra-thin Galaxy S25 Edge, including a redesigned motherboard and a 200MP camera sensor that saves space without sacrificing resolution. The Fold 7’s hinge mechanism was also overhauled to reduce bulk and minimize the infamous display crease, which rumors suggest could become “nearly invisible”.
However, trade-offs emerge. To maintain structural rigidity, Samsung reportedly retained an aluminum frame instead of adopting titanium. This choice balances weight savings against durability but risks lagging behind premium materials used in rivals like the Honor Magic V3. Additionally, internal space constraints likely forced the removal of the S Pen digitizer, ending built-in stylus support for the first time since the Fold.
Bigger Screens, Brighter Outlook
The Fold 7 expands both displays: the main screen grows to 8.2 inches (up from 7.6 inches), while the cover display reaches 6.5 inches, addressing long-standing user complaints about the narrow front screen. Both panels retain 120Hz refresh rates but may hit 2,900 nits peak brightness, enhancing outdoor visibility. Samsung’s new “ProScaler” tech could also upscale lower-resolution content for sharper visuals.
Performance and Camera Upgrades
Powering the device is Qualcomm’s Snapdragon 8 Elite chip, paired with up to 16GB of RAM. This promises notable speed gains over the Fold 6’s Snapdragon 8 Gen.. The camera system receives its biggest upgrade yet: a 200MP main sensor, matching the Galaxy S25 Ultra. It’s joined by a 12MP ultra-wide, a 10MP telephoto (3x zoom), and a modestly improved 4MP under-display selfie camera. AI enhancements are expected to optimize imaging and multitasking workflows.
Durability: The Unanswered Question
Samsung’s thinness pursuit raises concerns about longevity. User reports on Samsung’s forums cite inner screens developing “black lines of death” along the crease within two years, with replacements costing upwards of $425. One Fold 5 owner lamented, “Samsung, you’ve lost a loyal customer” after being denied a goodwill repair. While the new hinge may mitigate this, the Fold 7’s 4,400mAh battery (unchanged from the Fold 6) faces higher efficiency demands to power dual displays with minimal bulk. As tech analyst Janhoi McGregor notes, “Lithium-ion technology hasn’t advanced like other components… bigger is better”.
A Calculated Gamble
Samsung’s aggressive redesign arrives as competitors stall. Google’s Pixel 10 Pro Fold appears iterative, and OnePlus scrapped its 2025 foldable. This gives Samsung an opening to dominate with bolder changes. Priced at $1,899, matching the Fold 6, the Z Fold 7 bets that thinness and screen size will outweigh durability skepticism.
As Parker Burton, a YouTuber who tested the device, declared in Samsung’s teaser: “This is wildly thin.” Yet whether that thinness translates to reliability remains the pivotal question for a device costing as much as a premium laptop.
