SAMSUNG GALAXY Z FOLD 8 ULTRA

The Samsung Galaxy Z Fold 8 Ultra represents a significant milestone in the evolution of foldable smartphones. As the first device in Samsung’s Galaxy Z Fold series to carry the “Ultra” designation, it combines the productivity-focused DNA of the Fold line with the premium specifications and capabilities traditionally reserved for the Galaxy S Ultra models. Announced at Galaxy Unpacked in July 2026 and released on August 7, 2026, this device aims to deliver an uncompromising flagship experience in a foldable form factor.

Design and Build Quality

The Galaxy Z Fold 8 Ultra continues Samsung’s pursuit of thin and light foldable designs. When unfolded, the device measures just 4.1mm thick—a marginal reduction from the Z Fold 7’s 4.2mm—making it the thinnest foldable Samsung has produced to date. In its folded state, the phone measures 8.9mm, which is identical to its predecessor. The device weighs 215 grams, which is notably lighter than many traditional flagship smartphones, including the iPhone 17 Pro Max.

The construction incorporates Samsung’s Armor Aluminum frame for structural rigidity, while the front and back panels are protected by Corning Gorilla Glass Ceramic 3 and Gorilla Glass Victus 2 respectively. The phone carries an IP48 rating for dust and water resistance, providing adequate protection against accidental splashes and everyday mishaps.

A key design improvement is the refined Armor FlexHinge mechanism. Samsung has reduced the stiffness of the hinge and the strength of the magnets, making the device significantly easier to open while still holding its position securely. Tapered edges and a subtle indent on the side rails further facilitate one-handed opening. The result is a device that feels refined and polished, the product of multiple generations of iterative improvement rather than a dramatic reinvention.

Color options include Iris Purple, Graphite Gray, and Cream White as standard offerings. A Samsung.com exclusive color called Hojicha Green (or Dark Green in some markets) is also available.

Displays

The Galaxy Z Fold 8 Ultra features a dual-display configuration that serves as the device’s defining characteristic. The main inner display is an 8.0-inch Dynamic AMOLED 2X panel with a resolution of 2504 x 2256 pixels (QXGA+), delivering a pixel density of approximately 422 ppi. The cover display measures 6.5 inches with a resolution of 2520 x 1080 (FHD+). Both screens support a 120Hz adaptive refresh rate and 16 million colors.

Peak brightness has been increased to 3,000 nits, up from the Z Fold 7’s 2,600 nits, representing a 15% improvement that enhances outdoor visibility. Samsung has also applied a new anti-reflective coating to the inner display, which significantly reduces glare and reflections in bright environments.

The most notable display improvement concerns the crease. Through the combination of a redesigned hinge and a new Flex Titanium layer beneath the flexible panel, the visible fold line has been dramatically minimized. Multiple reviewers describe the crease as “near invisible” or “one of the most invisible-seeming creases” ever seen on a foldable. CNET’s reviewer noted that the anti-reflective coating and flatter hinge combine to make the crease barely perceptible during typical usage, even when running a finger across the center of the screen.

The inner display’s nearly square aspect ratio (approximately 1.11:1) remains a subject of debate. It excels for productivity tasks, document viewing, and multitasking, offering more vertical space for reading and scrolling. However, for widescreen video content, this aspect ratio results in significant letterboxing, limiting the advantage of the larger screen for media consumption.

Performance and Hardware

At the heart of the Galaxy Z Fold 8 Ultra is the Snapdragon 8 Elite Gen 5 for Galaxy processor, a custom-tuned chipset featuring an upgraded NPU, GPU, and CPU specifically optimized for Galaxy devices. The octa-core CPU operates at speeds of up to 4.74GHz and 3.6GHz.

The device comes with 12GB of RAM as standard in the 256GB and 512GB configurations, while the 1TB model is paired with 16GB of RAM. Benchmark testing reveals class-leading performance: Geekbench 6 scores of 3,659 (single-core) and 10,739 (multi-core) place the Fold 8 Ultra ahead of competing foldables including the Pixel 10 Pro Fold and Motorola Razr Fold. In 3DMark’s Wild Life Extreme test, the device achieved 6,221 at 37.26fps on the inner screen, demonstrating substantial gaming capability.

Storage options include 256GB, 512GB, and 1TB variants, with user-available storage on the base model measuring approximately 222-224GB after system software and pre-installed applications.

Cameras

The camera system represents one of the Ultra’s most significant advantages over the standard Galaxy Z Fold 8. The rear array comprises a 200-megapixel primary wide camera with f/1.7 aperture and optical image stabilization, a 50-megapixel ultra-wide camera with f/1.9 aperture (a substantial upgrade from the 12-megapixel sensor on the Z Fold 7), and a 10-megapixel telephoto camera with f/2.4 aperture offering 3x optical zoom.

The ultra-wide camera upgrade brings a 34% improvement in light gathering, enabling sharper and more vibrant low-light photography. The telephoto lens supports 2x optical-quality zoom through Samsung’s Adaptive Pixel sensor technology, with digital zoom extending up to 30x. The ProVisual Engine handles image processing, enhancing color rendition, detail sharpness, and low-light performance across all cameras.

Video capabilities include 8K recording at 30fps, with slow-motion capture available at 240fps in Full HD and 120fps in both Full HD and Ultra HD. For selfies and video calls, the device includes a 10-megapixel front camera on the inner display and a 10-megapixel cover camera, both with f/2.2 aperture.

Battery and Charging

The Galaxy Z Fold 8 Ultra is equipped with a 5,000mAh battery—the largest Samsung has ever placed in a foldable device, representing a substantial increase from the Z Fold 7’s 4,400mAh cell. The battery utilizes silicon-carbon technology, which theoretically offers improved energy density compared to traditional lithium-ion designs.

Real-world battery life has received generally positive assessments. PCMag UK’s testing yielded over 16 hours of continuous use, approximately three hours more than the previous generation. ZDNET and other reviewers report that the device comfortably lasts through a full day of heavy use. However, CNET’s controlled streaming test showed only marginal improvement over the Z Fold 7, suggesting that the larger battery and more efficient chipset are somewhat offset by the demands of the bright, high-resolution displays.

Charging speeds have improved significantly. The device supports 45W wired fast charging—up from 25W on the Z Fold 7—enabling a charge from empty to approximately 63-70% in 30 minutes. Wireless charging is supported at 15W (or 20W depending on the charger), along with 4.5W reverse wireless charging for accessories.

Software and AI Features

The Galaxy Z Fold 8 Ultra ships with Android 17 and Samsung’s One UI 9, both optimized for the foldable form factor. Galaxy AI features are deeply integrated throughout the experience, with several capabilities specifically enhanced for the larger inner display.

Now Nudge represents one of the more innovative AI features, proactively suggesting actions based on context. For example, when a dinner invitation arrives via messaging, Now Nudge can suggest adding it to the calendar and automatically open the relevant applications in a split-screen view. Gemini Notebook allows users to upload meeting notes or presentation recordings, generating summaries and even transforming content into AI-generated videos, presentations, podcasts, or quizzes.
