If you ever thought a foldable phone's external screen was only good for checking the time or seeing notifications, that's completely changed: the Galaxy Z Flip7's Infinity FlexWindow transforms that external screen into a true workspace and creative hub with integrated AI . Now you can reply to messages, start video calls, control the camera, or translate conversations in real time without opening your phone, with a fluidity reminiscent of an advanced watch but with a much richer interface.
The best part is that this leap isn't just aesthetic: with its 4,1-inch Super AMOLED panel, brightness of up to 2.600 nits , and 120Hz refresh rate , FlexWindow is no longer just an accessory, but the control center for everyday life. Fewer gestures, fewer interruptions, greater efficiency, all backed by hardware and software bearing the hallmark of Samsung's latest generation.
What is Infinity FlexWindow and why it matters
Infinity FlexWindow is the name of the Galaxy Z Flip7's outer panel, a 4,1-inch Super AMOLED display with end-to-end usability designed for performing real-world tasks with the phone folded. We're not talking about looking at a banner or opening a single widget, but about typing quick replies , checking your calendar, viewing map routes, managing live notifications, or taking selfies with the quality of the main camera.
Its larger size compared to previous generations and the combination of 120Hz + Vision Booster make navigating apps, reading, and scrolling comfortable even in direct sunlight. That extra brightness— up to 2.600 nits on the cover and also on the main screen—maintains visibility when you need it most, automatically thanks to adaptive modes.
Samsung's approach with Flip7 is clear: part of the phone experience already "lives" in the flip cover. As the product managers emphasize, the idea was for it not to feel like an add-on but rather a useful and quick tool; a place to perform actions in a matter of seconds without unfolding the phone.
This external window also interacts with the One UI 8 and Android 16 interface, so widgets and panels are optimized for one-handed use. Instead of encouraging you to open your phone, FlexWindow encourages you to stay closed to minimize distractions and speed up quick tasks.
Productivity, AI and usability on deck
The heart of this offering lies in its intelligence: FlexWindow is not only brilliant and fluid, but also deeply integrated with Galaxy AI . Without opening your phone, you can invoke voice help, request quick searches , execute actions, or receive contextual suggestions, all from the external screen with a minimal learning curve.
One of the key features is Gemini Live , available directly on the FlexWindow to act as a hands-free assistant. You can request flight details stored in Samsung Wallet, create reminders , search for highly-rated restaurants at your destination, or save information to Notes without touching the main screen. Even with camera sharing, simply point your phone at your suitcase or an outfit and ask, "What outfit is best suited for Seoul's weather?"
To keep you informed without losing track, FlexWindow includes Now Bar , a bar that displays real-time activity: podcast progress, playback status, sports scores, or estimated time of arrival for a trip. At a glance, you can see what's happening and react instantly without unfolding your device.
Now Brief is also included , a panel with personalized updates: traffic, reminders, calendar events, health summaries from Samsung Health, and even music and video recommendations . Everything adapts to your routine so that, every time you look at the cover, useful information is at hand and you don't have to navigate through menus.
Even the clock gets more practical: the new Stretch Clock "hugs" the wallpaper and adjusts the time in real time so as not to cover faces or objects. Whether you choose a close-up selfie or a landscape, the time will be integrated unobtrusively and always legible.
Displays and hardware: brightness, fluidity, and durability for everyday use
In addition to the FlexWindow, the Flip7 features a 6,9-inch Dynamic AMOLED 2X main display with FHD+ resolution (2520 × 1080, 21:9) and an adaptive refresh rate of 1 to 120 Hz. This combination allows for an immersive experience when the device is opened and optimized power consumption for static content thanks to the variable refresh rate.
The outer cover is a 4,1-inch Super AMOLED display with 1048 x 948 pixels and 342 ppi, capable of reaching 120 Hz. This is complemented by Vision Booster and high-brightness modes to ensure visibility outdoors, essential if you intend to interact with the Flip7 as often as you do outdoors.
Inside, it's powered by the Galaxy-customized 3nm Exynos 2500 processor , featuring CPU, GPU, and NPU upgrades over the previous generation. It's paired with 12GB of RAM and up to 512GB of internal storage , depending on the configuration. Plus, for the first time on a Flip, Samsung DeX allows you to transform the phone into a makeshift desktop by connecting it to an external display.
The battery has also been upgraded: it's a 4.300 mAh dual-cell battery with 25W fast charging (approximately 50% in 30 minutes in internal testing), Wireless Fast Charging 2.0, and Wireless PowerShare for sharing power with other compatible devices. Samsung estimates up to 31 hours of video playback under lab conditions with default settings, which aligns with the promise of longer battery life compared to its predecessor.
In terms of construction, the Flip7 is thinner and more durable. It weighs 188g , folds down to 13,7mm, and features Gorilla Glass Victus 2 on the front and back, Armor Aluminum for the frame, and a redesigned, thinner, and more robust Armor FlexHinge that improves the folding feel and overall durability. For water resistance, the specifications list the device at IP48 , subject to typical usage considerations (limited time and depth in fresh water). Furthermore, these premium materials are intended to directly contribute to the overall protection and longevity of the device.
Photography and creativity from the FlexWindow
Thanks to FlexWindow, the rear camera functions as the ultimate pocket selfie studio : you can frame and shoot without opening the phone and take advantage of the shared preview so the person being photographed can see themselves in real time. The main system combines a 50MP wide-angle lens with OIS and a 12MP ultra-wide-angle lens, delivering high-end, detailed selfies and videos right from the cover.
For nighttime video, Night Video mode intelligently separates subject and background to reduce noise, while 10-bit HDR delivers richer color and contrast. If you like to experiment, Real-Time Filters lets you preview styles and adjustments on your FlexCam shots; and with the new Zoom Slider, you can zoom in or out with a simple swipe—perfect for group selfies or full-body shots.
AI also enhances editing: with tools like Photo Assist you can erase elements, straighten or fill in backgrounds; Instant Slowmo instantly converts a clip to slow motion ; and Portrait Studio offers creative finishes like caricature or fisheye effect, adding that fun touch to portraits, even of pets.
In creative sessions, Flex mode allows you to prop the phone up at unusual angles, freeing your hands and eliminating the need for tripods. For creators, this translates into greater agility when recording content for social media and making better use of the Flip's form factor.
A step that began with the Infinity Flex Display. The story of this external screen has its roots in Samsung's foldable revolution. At the 2018 Samsung Developer Conference, the company first showcased the Infinity Flex Display , a 7,3-inch foldable AMOLED panel that folded inwards and was accompanied by a second front-facing screen for smartphone use. That technology incorporated a flexible protective polymer and a special adhesive designed to withstand folding cycles without peeling off.
In that prototype, the main screen offered 1536 × 2152 pixels (4.2:3 aspect ratio) with 420 ppi, and Android (in collaboration with Google) was adapted to support up to three simultaneous windows with adjustable sizes. The cover screen was around 4,58 inches at 1960 × 840. Since then, Samsung has brought that vision to commercial devices, refining materials, hinges, and software to this FlexWindow that now allows you to truly use the external screen, not just view it.
Beyond the camera, the experience is rounded out with security and ecosystem features. One UI 8 incorporates Knox Matrix and the new KEEP (Knox enhanced Encrypted Protection), a system that creates encrypted storage environments per app within the device's secure area to protect personalized AI-powered features. This is complemented by Samsung Knox Vault and a comprehensive array of sensors: side-mounted fingerprint reader, accelerometer, barometer, gyroscope, geomagnetic sensor, Hall sensor, proximity sensor, and light sensor, among others.
Connectivity is comprehensive: 5G and LTE depending on the market, Wi-Fi 7 (where available), Bluetooth 5.4, eSIM, and nano SIM. It also supports Samsung Wallet for payments and cash management, and integrates with Galaxy wearables, which is reflected in personalized Now Brief summaries and wellness data synced with Samsung Health.
For those looking to experience foldable phones, Samsung has also announced the Galaxy Z Flip7 FE , featuring a 6,7-inch main screen, a 50MP FlexCam designed for hands-free video and photography in Flex mode, and an external display that shows Now Brief with weather, calendar, and traffic updates in a compact format. It retains Galaxy AI features such as real-time translation and call summaries.
If you're interested in where to get it, the Flip7 appears in carrier catalogs with financing options and launch promotions. In markets like Argentina, Samsung has confirmed availability with configurations of 12GB + 512GB for the Flip7 and 8GB + 256GB for the Flip7 FE, in addition to coverage options like Samsung Care+ and upgrade programs.
To conclude this review, it's worth listing the key features of the Infinity FlexWindow display and its surroundings on the Flip7: a 4,1-inch Super AMOLED cover (1048 × 948, 120 Hz, up to 2.600 nits), a 6,9-inch Dynamic AMOLED 2X main display (FHD+, 1–120 Hz), Vision Booster, integration with Galaxy AI (Gemini Live, Now Bar, Now Brief, Stretch Clock), fluid touch response , premium materials, and a design that finally takes real advantage of the external screen for working, communicating, and creating without unfolding it.
At this point, the Galaxy Z Flip7's FlexWindow makes it clear that what matters isn't just the size, but the intelligence with which it's used . Between high brightness, a 120Hz refresh rate, multimodal AI, and an interface optimized for outdoor use, the cover goes from being a simple "lid" to becoming a useful space for productivity, photography, and personalization, as well as marking the evolution of that first Infinity Flex Display that paved the way for Samsung's foldable devices.
