Samsung Galaxy Tab S12 Ultra Review: A Powerful Android Tablet With a Stunning Display

The Samsung Galaxy Tab S12 Ultra combines a massive 14.6-inch AMOLED display, flagship performance and advanced productivity tools, making it one of the most capable Android tablets available. However, its premium price and limitations as a laptop replacement may give some buyers pause.

Samsung’s latest flagship tablet, the Galaxy Tab S12 Ultra, aims to deliver a premium experience for professionals, students, content creators and entertainment enthusiasts. Launched alongside the Galaxy Tab S12+, the device brings upgraded processing power, an improved cooling system and the latest Galaxy AI features to Samsung’s large-screen tablet lineup.

Although the new model retains much of the design philosophy of its predecessor, its updated hardware and software are intended to make demanding tasks smoother and everyday productivity more convenient.

Samsung Galaxy Tab S12 Ultra Review: Design and Build Quality

The Galaxy Tab S12 Ultra continues Samsung’s focus on an exceptionally slim, premium design. Measuring just 5.1mm thick and weighing approximately 692 grams in its Wi-Fi configuration, the tablet offers a remarkably thin profile for a device with such a large display.

Its large dimensions make it particularly suitable for desk-based productivity, creative work and multitasking. However, using it for extended periods with one hand or carrying it around like a conventional compact tablet may prove less comfortable.

Samsung has also included an IP68 rating for dust and water resistance, providing additional protection during everyday use. The overall design prioritises a combination of portability, durability and a spacious working area.

Display: A 14.6-Inch AMOLED Panel Takes Centre Stage

One of the Galaxy Tab S12 Ultra’s biggest attractions is its 14.6-inch Dynamic AMOLED 2X display. With a resolution of 2,960 x 1,848 pixels and an adaptive refresh rate of up to 120Hz, the screen is designed to deliver sharp images, smooth scrolling and vibrant colours.

The panel supports peak brightness of up to 1,600 nits, helping improve visibility in brighter environments. Its expansive viewing area is particularly useful for watching films, editing photographs, reading documents and working with several applications simultaneously.

For users who regularly draw or take handwritten notes, the large screen also provides ample room for the included S Pen. Combined with Samsung’s multitasking features, the display is one of the tablet’s strongest selling points.

Performance: MediaTek Dimensity 9500 Powers the Experience

Samsung equips the Galaxy Tab S12 Ultra with MediaTek’s Dimensity 9500 processor, built on a 3nm manufacturing process. The flagship chipset is designed to handle demanding applications, intensive multitasking and graphics-heavy games.

Depending on the configuration, buyers can choose up to 16GB of RAM and 1TB of internal storage. The tablet also supports microSD cards of up to 2TB, giving users additional room for documents, videos, photographs and other large files.

A redesigned 3D vapour-chamber cooling system is intended to help maintain performance during demanding workloads. This should benefit users who regularly edit media, play games or run several applications at the same time.

Nevertheless, actual performance will depend on the application, workload and software optimisation. Android’s application ecosystem also remains an important consideration for professionals who rely on specialised desktop software.

Software and Galaxy AI Features

The Galaxy Tab S12 Ultra runs Android 17 with Samsung’s One UI 9 interface. The software introduces a range of productivity tools, including multitasking capabilities, split-screen functionality and access to Samsung DeX.

Galaxy AI features are designed to assist with everyday activities such as writing, organising information and working with digital content. Their usefulness will depend on the specific feature, supported applications and availability in each market.

The included S Pen further expands the tablet’s capabilities, allowing users to write notes, annotate documents, sketch ideas and interact with supported applications.

Samsung’s long-term software commitment is another advantage, with the company promising up to seven generations of operating system upgrades and seven years of security updates.

Battery Life and Charging

The Galaxy Tab S12 Ultra packs an 11,600mAh battery, providing a substantial power reserve for a tablet designed around productivity and entertainment.

Samsung advertises battery life of up to 23 hours under its specified test conditions. Actual endurance will vary depending on screen brightness, connectivity, gaming, video playback and multitasking.

The device supports 45W wired charging, although charging speeds and the time required to reach a full charge can vary. Users should also check the accessories included with their regional model before purchasing a compatible charging adapter.

For people who spend long hours working away from a power outlet, the combination of a large battery and efficient hardware makes the tablet a potentially practical companion.

Cameras and Audio

On the rear, the Galaxy Tab S12 Ultra features a 13MP main camera accompanied by an 8MP ultra-wide sensor. The front-facing camera is a 12MP ultra-wide unit designed for video calls and online meetings.

While the camera system is unlikely to replace a flagship smartphone for photography, it provides the functionality expected from a premium tablet. The front camera is particularly relevant for students attending online classes and professionals participating in video conferences.

Samsung also equips the device with four speakers configured for four-channel spatial audio. This setup is designed to provide an immersive listening experience when watching films, playing games or listening to music.

Is the Galaxy Tab S12 Ultra a Laptop Replacement?

With its large display, powerful processor, S Pen support and Samsung DeX, the Galaxy Tab S12 Ultra can handle many tasks traditionally associated with laptops.

It is well suited to document editing, research, presentations, note-taking and media consumption. Paired with a compatible keyboard accessory, it can also provide a more conventional typing experience.

However, it is not a complete replacement for every laptop. Some professional applications, advanced desktop workflows and specialised software remain better suited to Windows or macOS computers. Buyers should also consider the additional cost of a compatible keyboard if they intend to use the tablet primarily for work.

For users whose workloads are largely browser-based or centred on Android applications, the Tab S12 Ultra could be a capable productivity device. Those who depend on full desktop software may still need a traditional computer.
