The future of foldable phones is no longer a distant promise: with the Samsung Galaxy Z TriFoldThe South Korean brand has opened a new category that goes beyond the classic Fold and Flip, with OPPO's first foldable phone. This device folds twice, transforming from a pocket-sized phone into a large 10-inch screen, and aims to be a true tablet and even laptop replacement in many scenarios.
This new triple folding unit combines Ultra-high-end hardware, highly refined engineering, and meticulously crafted software So that the experience goes beyond the eye-catching design. From its titanium hinges to the integration of Galaxy AI, including standalone Samsung DeX and a three-cell battery, everything is designed to make it not just "a weird phone," but a serious productivity and entertainment tool, with options to personalize your mobile device.
What is the Galaxy Z TriFold and why is it so special?
The Galaxy Z TriFold is the Samsung's first commercially available triple-folding phone, the result of a decade of development in the range of foldable devices and previous attempts such as the ZTE Axon MIts body consists of three panels that fold inwards, so that the main screen is protected and, when fully unfolded, it offers a 10-inch diagonal with QXGA+ resolution.
Samsung's idea with this device is to solve a problem that the mobile industry has been grappling with for years: how to offer large screens for working and enjoying content without sacrificing the portability of a mobile phone. In practice, the TriFold behaves as if you had three 6,5-inch mobile phones stuck togetherwhich you can use as a single giant screen or in several sections for different tasks, taking advantage of tricks to Optimize apps on foldable devices.
The format isn't just a design flourish. Samsung has enhanced the experience with Galaxy AI, standalone Samsung DeX, next-generation connectivity, and meticulous construction, aiming to make the TriFold feel like a finished product and not an expensive prototype.
Design, hinges and materials: custom engineering
To allow a phone to fold twice without becoming a brick in your pocket, Samsung has had to rethink virtually the entire internal design. At its thinnest point, the Galaxy Z TriFold has only 3,9 mm thick when fully unfolded, a figure that places it even below many traditional flat mobile phones.
The secret lies in a new generation of Armor FlexHingesInstead of one hinge, the TriFold uses two hinges of different sizes with a double-rail structure that work in coordination. This allows for a balanced distribution of weight and internal components, a more stable closure, and minimizes the gap between panels when folded, resulting in a thinner and more compact device.
The folding pattern is unique: the device closes in a U-shape and You should always start by folding the left panel and then the right one.If you make a mistake, the phone won't stay silent: it will vibrate and display an on-screen warning indicating that the closure is incorrect. It might seem strange at first, but after a few minutes of use, the gesture becomes second nature and serves to protect both the mechanism and the internal screen.
On the outside, the TriFold combines a titanium hinge housing with an Advanced Armor Aluminum frameA high-strength alloy provides rigidity without adding bulk to the device. This frame is designed so that the screens never touch each other when folded. The back uses a fiberglass-reinforced polymer and ceramic, which helps keep the thickness down while improving resistance to cracks and impacts.
The manufacturing quality is backed by very meticulous factory control: each unit goes through computed tomography (CT) scans of the flexible circuit To ensure it matches the design, laser scans are also used to verify that all components are at the correct height and position. The goal is to minimize assembly errors in this extremely complex device.
Screens: 10 inches of productivity and cinema in your pocket
The central element of the Galaxy Z TriFold is its 2-inch Dynamic AMOLED 10X main displaywith a resolution of 2160 x 1584, a pixel density of 269 ppi, and a maximum brightness of 1600 nits. It supports an adaptive refresh rate of 1 to 120 Hz, allowing the refresh rate to be adjusted according to the content to save battery or achieve maximum smoothness when needed; this adaptive refresh rate It is key to energy consumption in large screens.
On the outside, when the phone is folded, you find a 6,5-inch FHD+ cover display (2520 x 1080, 21:9 aspect ratio and 422 ppi), also Dynamic AMOLED 2X, with up to 2600 nits of peak brightness and a 120 Hz adaptive refresh rate. This is the screen you'll use for most quick tasks, notifications, social media, or light browsing when you don't need to unleash the full potential of the device.
Both screens offer 100% mobile color volume in the DCI-P3 gamutAccording to Samsung's internal tests, this prevents washed-out colors and maintains vibrant tones at different brightness levels. Vision Booster technology adjusts contrast and saturation based on ambient light, which is crucial when using the 10-inch screen in bright sunlight.
To withstand the two folds, Samsung has redesigned the internal screen structure. Beneath the flexible layer, additional material has been added. a reinforced protective layer capable of absorbing impactsThis increases resistance to accidental pressure and wear from continuous opening and closing.
In daily use, the creases are there, but They're no more annoying than they are on a Galaxy Z Fold7You can feel where they are when you swipe your finger across them, but when consuming content, watching videos, or playing games, your eyes adjust quickly and they barely interrupt the experience. Where the difference with other foldable phones is most noticeable is in the format: with a 10-inch screen, watching series, movies, or YouTube with the phone unfolded feels very similar to using a dedicated tablet, with the added benefit of being able to watch a video and read comments simultaneously on the same screen.
Dimensions, weight and ergonomics: mobile phone, tablet and more
In numbers, the Galaxy Z TriFold measures 159,2 x 75,0 x 12,9 mm folded and 159,2 x 214,1 x 3,9-4,2 mm when unfolded, depending on the panel used as a reference. The weight is 309 grams, not including the pre-installed screen protector. It's not a lightweight phone, but considering it integrates what is practically equivalent to a 10-inch tablet, the result is quite well-balanced.
When folded, its 12,9 mm thickness is not excessive: in fact, many users comment that It's similar to carrying a high-end phone in a thick case.like a Galaxy S24 Ultra with a rugged case. The 21:9 aspect ratio of the external screen makes it easy to grip and remove from your pocket while sitting, although the extra thickness sometimes means you accidentally touch the camera lenses with your fingers.
One curious detail of the design is that, once folded, The rear cameras are what's facing you.not the external screen. To see the latter, you have to rotate the phone, which in certain situations disrupts the flow of use. For example, if you're on a video call on the main screen and decide to fold the device without hanging up, it takes a few extra seconds to switch back to the main screen and continue the conversation.
Ultra-high-end performance: Snapdragon 8 Elite and 16 GB of RAM
Inside, the Galaxy Z TriFold features the Snapdragon 8 Elite mobile platform for Galaxy manufactured in 3nmA customized version for Samsung that prioritizes sustained performance and energy efficiency. It's the same core found in the most powerful Galaxy models, adapted here to the demands of a triple-folding design.
The device is sold in configurations of 16 GB of RAM with 512 GB or 1 TB of internal storageThere's no microSD card slot, so choose the right capacity based on your needs (especially if you'll be storing videos, offline content, or large projects). Part of the value proposition is complemented by the 2TB of cloud storage offered by Google AI Pro for six months, but that doesn't replace local storage when working offline.
The combination of CPU, GPU, and memory is designed to handle tasks with ease. extreme multitasking, video editors, productivity tools, and demanding games on that large 10-inch screen. Furthermore, Galaxy AI and DeX features take advantage of that extra processing power to handle AI tasks both locally and in the cloud.
Cameras: 200 MP sensor and versatile zoom
In terms of photography, Samsung has opted for a setup very similar to that of its most recent high-end models. On the back, we find a 200MP wide-angle camera With Quad Pixel autofocus, an f/1.7 aperture, optical image stabilization (OIS), 0,6 μm pixel size, and an 85° field of view, this sensor enables 2x optical zoom by cropping the 200 MP image, improving detail without resorting to aggressive digital zoom. If you want to get the most out of this type of sensor, the tips for taking photos with your mobile phone they are very useful.
Next to the main one there is a 12 MP ultra wide angle With Dual Pixel AF, f/2.2 aperture, 1,4 μm pixels and a 120° field of view, it's ideal for landscapes, architecture, or indoor scenes where you want to capture more without moving.
The trio closes with one 10MP telephoto camera With PDAF, OIS, an f/2.4 aperture, 1,0 μm pixels, and a 36° field of view, it offers 3x optical zoom and up to 30x Space Zoom by combining 3x optical and 10x digital zoom, powered by AI Super Resolution. Beyond 3x, image quality begins to degrade, but it remains useful for occasional distant shots.
On the front there are two 10 MP cameras: one in the cover screen (F2.2, 1,12 μm, FOV 85°) for quick selfies and video calls with the phone folded; and another in the Main screen (F2.2, 1,12 μm, FOV 100°) Designed for video conferencing and selfies with a slightly wider field of view when you're working or enjoying content on the big screen.
The photographic experience is enhanced with Galaxy AI: features such as Photo Assist, Generative Editing and “Sketch to Image” They allow you to retouch photos, remove elements, fill backgrounds, or transform doodles into more elaborate images. Furthermore, the interface makes excellent use of the 10-inch screen to display before/after comparisons side-by-side without feeling overwhelming.
Three-cell battery and fast charging
One of the challenges of a phone like this is powering such a large screen without significantly impacting battery life. Samsung has opted for a 5600 mAh three-cell battery systemdistributed across each of the device's panels. The nominal value is 5437 mAh, and the typical value, tested by third-party laboratories, is 5600 mAh. If you're looking for battery life comparisons, models like the Nubia Z80 Ultra They show different approaches to capacity and energy management.
This distribution allows a more balanced energy distribution and better thermal managementThis is key to preventing heat from concentrating in a single spot when you're pushing the device with DeX, games, or advanced multitasking. Actual battery life, as always, depends on usage: spending hours with the 10-inch screen at 120Hz and high brightness will drain the battery faster than if you primarily use the external display.
While charging, the Galaxy Z TriFold is compatible with 45W ultra-fast charging 2.0According to Samsung's internal tests, with the official 45W charger and a 3A USB-C cable, it can recover around 50% battery in about 30 minutes, with the device turned off and no background services running. It also features 15W fast wireless charging 2.0 based on the Qi standardand with Wireless PowerShare to charge other compatible devices, such as watches or headphones, simply by placing them on its back.
The choice of 5600 mAh may seem low compared to similarly sized tablets, such as certain Galaxy Tabs with over 8000 mAh, but it's important to keep in mind that here the priority is the balance between thickness, weight and usabilityIn practice, many analysts point out that the result is reasonable: it's not a "marathoner," but you can spend the day combining work and leisure if you manage your use of the big screen well.
Software, multitasking, and standalone Samsung DeX
While the hardware is eye-catching, it's the software that truly justifies the form factor. The Galaxy Z TriFold arrives with Android 16 and One UI 8A version of Samsung's interface specially optimized for large screens and multiple windows. On the 10-inch screen, you can have up to three full applications open at the same time In a vertical orientation, placed side by side, plus additional floating windows that you can resize and move as you like. Furthermore, there are app kits that help to take advantage of unconventional screens.
This way of working is much more similar to using a PC or an ultrawide monitor than a traditional tablet. You can, for example, Review plans in a design app, write a proposal in a word processor, and perform calculations in a spreadsheet.all simultaneously, without having to constantly switch between applications. And if a call comes in, you can answer it without disrupting your workspace; furthermore, other more compact foldable laptops, like the Nubia Flip 2They offer more budget-friendly alternatives.
The taskbar, located at the bottom right of the screen, displays recent applications and allows you to retrieve them. with one touch the same window arrangement that you were using, something especially useful when you're switching between work and leisure during the day. Apps like My Files or Samsung Health have also been adapted to the larger screen, presenting more information at a glance and reducing the number of taps needed to navigate.
One of the strengths of the TriFold is that it is the Samsung's first mobile phone with "standalone" DeXIn other words, you can activate DeX directly on the 10-inch screen without needing an external monitor. From the quick settings panel, selecting DeX transforms the device into a desktop environment with up to four virtual desktops, each capable of running five applications simultaneously.
If you need even more space, you can connect an external monitor and use extended mode for a dual-screen setupIn this mode, it is possible to drag and drop applications between the TriFold and the monitor, work with a Bluetooth mouse and keyboard, and, in practice, mimic the experience of a desktop laptop in a format that still fits in your pocket.
Galaxy AI and Gemini Live: AI adapts to the triple format
The other major feature of the device is artificial intelligence. Galaxy AI is integrated into the TriFold to streamline everyday tasks by leveraging the large display area and the power of the Snapdragon 8 EliteIn addition to the photo editing functions already mentioned, we find tools such as "Browsing Assist", which summarizes web pages or translates content directly on Samsung Internet, without having to copy and paste anything.
Gemini Live, Google's conversational AI experience on mobile, is also making a leap in this format. Thanks to the Multimodal AIGemini understands what you see, say, and do. You can have a voice conversation while showing it the camera pointing at a room, a shopping page, and paint swatches, and get personalized design recommendations without leaving the application you were in.
With the screen sharing or camera sharing function within Gemini Live, you can ask contextual questions about what's on the screen and receive real-time explanations or suggestions. The TriFold's large screen makes it easy to have the conversation with Gemini, the reference content, and other apps open at the same time, without feeling overwhelmed.
Durability, connectivity, and security
In terms of protection from the elements, the Galaxy Z TriFold features IP48 certificationThis means it is protected against the ingress of solid objects larger than 1 mm and can withstand immersion in fresh water up to 1,5 meters for a maximum of 30 minutes. It is not intended for the beach or swimming pool, and its water resistance may decrease over time due to wear and tear from continuous use. Furthermore, it is not resistant to fine dust or sand.
Connectivity is on par with an ultra-range device: we have 5G, LTE, Wi-Fi 7 and Bluetooth 5.45G and LTE availability depends on the market and carrier; if you have questions about network support or services, check what Mobile phones are compatible by operator in your country. Actual speeds may vary depending on the network and environment. To take advantage of Wi-Fi 7, you'll need a compatible router and a suitable connection, but the hardware is ready for high-capacity networks.
Regarding sensors, the device includes capacitive side fingerprint readeraccelerometer, gyroscope, barometer, geomagnetic sensor, Hall sensor, proximity sensor, and light sensor. For safety, it relies on Samsung Knox and Samsung Knox Vaultwhich protect both the operating system and the most sensitive data at the hardware level.
For communications, the TriFold supports up to two physical Nano SIM cards and multi eSIMCompatibility with eSIMs varies depending on the region and carrier. It's best to confirm with your carrier before purchasing if this is a critical factor for you.
User experience: Does it really work as a tablet and laptop replacement?
Beyond the specifications, what many are wondering is whether this triple-folding format makes sense in everyday life. The answer, for many analysts and users who have tested it, is that the Galaxy Z TriFold is the closest we've come to having a "complete PC in your pocket"The combination of a 10-inch screen, a tailored One UI 8, standalone DeX, and powerful hardware makes tasks you previously reserved for your computer completely feasible on your mobile device.
Sign contracts, review and edit complex documents, manage spreadsheets, prepare presentations by sharing your screen, use it as teleprompter for videos Carrying multiple apps open for background tasks are scenarios where the TriFold feels particularly comfortable. The multi-screen format and true multitasking give it a clear advantage over other foldable phones geared solely towards entertainment.
However, it's not all perfect. The battery, while reasonable, can feel a bit limited if you use the large screen for many hours at a time. The thickness and weight, although well-resolved, are still a drawback. a compromise versus a traditional mobile phoneAnd the price is clearly niche. But for those who need a highly versatile professional device, or for those who want the latest in format and technology, it's a game-changer.
One fact that speaks for itself is that, in South Korea, the Galaxy Z TriFold It sold out in minutes on the day of its launch in the approximately 20 selected physical stores. Despite a price of around 3,59 million won (about 2.100 euros at the current exchange rate, probably more with taxes in Europe), the queues and interest demonstrated that there is a public willing to invest in this type of first-generation device, trusting in Samsung's experience after seven series of Fold and Flip.
Availability, price, and promotion with Google AI Pro
Samsung has confirmed that the Galaxy Z TriFold will be Available first in Korea on December 12, 2025It will then be rolled out to other markets such as China, Taiwan, Singapore, the United Arab Emirates, and the United States. During the launch phase, it will be offered in select stores so users can try it out and receive specific advice on the new format.
In Korea, its starting price is around 3,6 million won (about 2.100 euros or 2.500 dollars)There is no official confirmation for other European countries, and in some markets, such as Spain or Mexico, the brand itself has hinted that no immediate plans to market it, at least in the first wave.
As an incentive, Samsung includes a TriFold purchaser's six-month free trial of Google AI ProThis service offers advanced access to the Gemini app, including video generation powered by Veo3 technology, as well as 2 TB of secure cloud storage. After the trial period ends, the subscription costs $19,99 per month (US reference price, which may vary by country) unless you cancel beforehand, and returning the purchased device may result in cancellation of the offer.
In addition, the brand has announced an exclusive screen repair advantage For TriFold owners: all buyers will be entitled to a one-time 50% discount on screen repair costs, a way to alleviate concerns about damage to a flexible panel of this caliber; if you need information on how much it might cost change the mobile screenThat guide is very useful.
The Galaxy Z TriFold is positioned as the most ambitious and productivity-oriented foldable Samsung has launched to date, a device that truly blurs the line between mobile and tablet and that, for a certain type of professional and enthusiast user, can justify its price: a very thin triple foldable format, the largest screen ever seen on a Galaxy, ultra-range power, advanced AI and a near-computer experience in a device that fits in your pocket.
