Samsung Galaxy Z Fold 8 Review: The Foldable Many Buyers Have Been Waiting For

The Galaxy Z Fold 8 is one of three foldables Samsung announced at its July Unpacked event, and it breaks from the Fold formula. Instead of a tall, narrow shape, it is short and broad when closed. Google, OPPO and HUAWEI shipped wide foldables before it, but this is the highest-profile Android take on the idea, and it arrives at the same time as Apple's debut foldable, the iPhone Duo, which is its most obvious competitor.

Design and build

9mm tall, which makes it shorter than compact Android models such as the Galaxy S26 and Pixel 11, and shorter even than the iPhone 13 Mini.

Size is the first thing that stands out. The phone is 123.9mm tall, which makes it shorter than compact Android models such as the Galaxy S26 and Pixel 11, and shorter even than the iPhone 13 Mini. Closed it measures 9.7mm thick; opened, 4.5mm. That is only slightly chunkier than a Galaxy S23 Ultra, a sign of how far foldables have come by 2026. At 201 grams it weighs less than the Galaxy Z Fold 8 Ultra and a good deal less than the iPhone Duo.

The aluminum frame has thin, flat sides. Samsung pairs it with a Flex Titanium hinge that it says helps with impact resistance and keeps the crease in check, plus Gorilla Glass Victus 2 on the rear panel. In one accidental 1.2-meter fall onto a tiled floor, opened and uncased, the handset survived with no visible damage and kept working normally. A single incident proves little, but it is encouraging.

The corners are fairly sharp. They are less aggressive than on older Ultra models and do not press into the palm, though softer rounding would be nicer; the approach is still preferable to the iPhone Duo and Xiaomi 18 Fold, whose folded shape mixes sharp corners on one side with rounded ones on the other. The position of the camera bump makes the phone rock badly when either screen is tapped while it lies flat on a table, and a Pixel-style camera bar would have avoided that.

The most serious hardware shortcoming is the IP48 rating. The phone can survive submersion in fresh water but carries no meaningful dust protection, while rival makers offer IP58 or IP68. That makes it a poor companion for a beach trip and raises questions about how it will hold up as grit builds up over time.

A 4:3 inner display

The folding panel measures 7.6 inches, and its 4:3 aspect ratio is the main reason to choose this model. Previous Folds used a near-square shape that suits side-by-side apps but leaves black bars around both 16:9 and 4:3 video, so the usable picture is barely bigger than on a normal phone. Here, older 4:3 material such as Buffy the Vampire Slayer and Columbo fills the whole display. Widescreen video still shows bars, though they are much thinner than on a conventional Fold, even if the actual picture area ends up about the same.

The Kindle app opens in a two-column layout by default, as it did on the original Pixel Fold and OPPO's early foldables, so ebooks resemble an open paperback. Nintendo DS emulation is another highlight: held upright, the screen splits into a top and bottom half like the original handheld, without feeling cramped. Button-heavy titles are less suited, but touch-driven games such as Advance Wars: Dual Strike and Trauma Surgeon work well.

The crease is well controlled. It can just be felt under a fingertip, so it is not as invisible to touch as OPPO's best effort, and it remains visible from an angle or with the screen switched off. It is clearly milder than on the vivo X Fold 5 (no side-by-side check against the Z Fold 7 was possible). Creases are not eliminated yet, though for many buyers this is good enough, and Apple has not removed one either.

Downsides remain. The plastic surface collects fingerprint smudges that become obvious with dark mode enabled or once the screen dims at very low battery, even though the bright panel and anti-glare coating keep reflections down. Samsung also warns that a fingernail can mark the screen. Most apps scale properly, but Instagram and Slack leave a lot of empty white space unless the phone is turned to portrait.

Samsung has dropped Flex Mode, so the phone no longer stays half-open like a small laptop. That hurts for video viewing, which now means tent mode or propping it against something, for playing emulated games with a controller, and likely for timed group photos. The upside is that the Fold 8 opens very easily, which some will consider a fair exchange, although a spring-loaded hinge would have appealed to retro-phone fans.

Cover screen

For most owners the 5.5-inch outer display will see the most use. Its broad 16:10 shape recalls the 4:3 LG Optimus Vu. Because the phone is so short, it is less awkward than expected, but reaching the corners still requires shifting the phone in the hand, much as on any large phone. One-handed mode is present, though software aids along the lines of Apple's or HUAWEI's would help. Apps generally adapt well; Instagram is an exception, displaying less content and often letterboxing Stories.

Performance

Inside is the Snapdragon 8 Elite Gen 5 for Galaxy, with 12GB to 16GB of RAM and 256GB to 1TB of storage. In Geekbench 6, single-core results essentially match the Galaxy S26, which uses the same chip, while the S26 pulls ahead in multi-core. The Fold 8 still beats the Z Fold 7.

Sustained graphics loads are a weak spot, as the cramped body limits cooling. Stability in all three GPU stress tests landed between 46% and 49%, so more than half of peak performance disappears under long loads, a concern for 8K recording, emulation and the most demanding games. The phone did run cooler than the Galaxy S26 and never became uncomfortably hot.

Day-to-day use is smooth: apps open quickly, multitasking and the camera behave, War Thunder plays fluidly at default settings with room to raise them, and GRID Legends runs smoothly on its "graphics" quality preset.

Battery and charging

The 4,800mAh cell is modest by 2026 standards but large for a Samsung foldable and a step up from the Z Fold 7's 4,400mAh. Even so, the Z Fold 7 outlasted it in most of the standardized battery workloads, with 4K recording the exception; the sharper inner display or immature software may be to blame, though that is speculation. The Fold 8 beat the Pixel 11 Pro Fold (4,806mAh, Tensor G6) in every category and topped the Razr Fold, which has a near-identical chip and a 6,000mAh battery, in most of them, pointing to effective software tuning by Samsung.

Real-world endurance is strong. Mixed use of WhatsApp, Instagram, Reddit, YouTube and local video, with about 90% of time on the cover screen and the inner display used for videos, reading and games, produced eight to ten hours of screen-on time and just under two days per charge. Heavier inner-screen use will drain it faster, yet a full day should be realistic in most cases.

Charging tops out at 45W wired and 20W wireless. A 2% to 100% charge took 67 minutes in benchmark testing, peaking around 38W, well short of the 45W rating; a separate charge from empty took 64 minutes. That is not fast for a foldable, but it is respectable for 2026, good for Samsung and far quicker than the Pixel 11 Pro Fold's 102 minutes. The phone runs very warm early in the charge before cooling quickly.

Cameras

The hardware is modest even among foldables: a 50MP 1/1.56-inch main sensor and a 50MP ultrawide. The main camera usually produces pleasing, detailed images, though some scenes show fringing, blotchy areas and overly neon colors, including in selfies. The ultrawide is decent apart from soft corners, and the 1x lens captures noticeably brighter low-light shots.

Zoom is the biggest weakness because there is no telephoto camera, even though 2021's OPPO Find N, the first wide foldable, had one. At 2x results range from solid to good; past 3x or 4x they are usually poor, with occasional surprises such as a decent 4x mountain landscape, and 10x is rarely worth trying. Portrait mode at 2x produces pleasant, mostly accurate background blur.

Video is a strength. Footage stays smooth with little judder when panning or tilting, and options include 4K/60fps, 8K/30fps and 4K/120fps, along with LOG and the APV codec for more serious work.

The new My FanCam tool in the Gallery picks out a person in a recorded clip and crops the footage around them, so a parent could isolate a child from a wide shot of a school play. Results can be rough, with artifacts and missing detail that make the crop obvious. Clips shot in 8K are exported in 8K rather than a more sensible 4K, which makes the upscaling look worse, and pets are not supported. The idea is promising but needs refinement.

Software

The phone runs One UI 9 on Android 17. Call Brief is meant to surface "events and other information" during calls, but Samsung is vague about what that means and no such prompts appeared during the review period. Now Nudge, carried over from One UI 8.5 as a rival to the Pixel's Magic Cue, supposedly reads on-screen content to offer suggestions, yet it also failed to show up, an issue Magic Cue had at launch too.

Custom Now Brief cards are a welcome, overdue addition. Weather cards can show rain probability, severe weather alerts, pollen index or sunrise and sunset; health cards can show weekly activity, sleep score and water intake. A YouTube category with tech, finance, gaming and travel topics feels pointless when the app itself is a tap away, and folding Routines Plus custom cards into Now Brief would make more sense.

Other new features include gesture wake-up for Bixby, Motion Assist and an AI assistant activity dashboard, alongside separate home screens for each display, the Good Lock apps and DeX, which unfortunately is not available on the inner screen. Samsung promises seven years of OS and security updates, which should carry the phone to Android 24.

Verdict

The Galaxy Z Fold 8 offers the shape the Fold line arguably should have had from the start: an inner screen built for media and a closed size that makes ordinary phones feel oversized. Strong battery life, reasonable charging, smooth everyday speed and feature-rich software add to the appeal.

Several shortcomings are hard to excuse at $1,899. The lack of any dust protection stands out when almost every competing foldable offers IP58 or IP68. There is no telephoto camera, which keeps it from being a complete flagship. S Pen support, offered on Folds until last year, is gone, and the iPhone Duo supports a stylus and keeps Flex Mode. The price undercuts Apple but still feels high given what is missing.

For buyers with money to spare, the Fold 8 is easy to recommend for its form factor alone. Those who care about the finer points may do better waiting for a Z Fold 9 or a competing wide foldable that addresses them.

Alternatives

The iPhone Duo ($1,999 at Amazon) is the main rival, with a similar shape plus IP68 protection, Flex Mode and Apple Pencil support, at a slightly higher price and with iOS. The Galaxy Z Fold 8 Ultra ($2,099.99 at Amazon) gives up the wide inner screen and compact build but brings stronger cameras, a display better suited to multitasking and a slightly bigger battery.
