Samsung Galaxy Tab S12+ Specifications, Features and Performance

The Samsung Galaxy Tab S12+ is a premium Android tablet designed for productivity, entertainment and everyday use. It features a 12.6-inch Dynamic AMOLED 2X display, a MediaTek Dimensity 9500 processor, 12GB of RAM and a 10,600mAh battery.

The tablet runs on Android 17 with Samsung's One UI 9 interface and supports up to seven major Android OS upgrades. It also features S Pen support, Samsung DeX, four stereo speakers, expandable storage and IP68-rated dust and water resistance.

Samsung offers the Galaxy Tab S12+ with 256GB or 512GB of internal storage, with both configurations featuring 12GB of RAM. Users can also expand the storage with a microSDXC card. A cellular version provides 5G connectivity for those who need mobile internet access away from Wi-Fi networks.

Design and Build Quality

The Samsung Galaxy Tab S12+ has a slim design, measuring 289.5 x 187.8 x 5.3mm. Its weight is listed as either 553g or 555g, depending on the model.

The tablet features a glass front, an aluminium frame and an aluminium back. Samsung also lists Enhanced Armor Aluminum among its build features.

Its slim body makes it suitable for carrying between home, school and work. However, the large display may make prolonged one-handed use less comfortable than using a smaller tablet.

The Galaxy Tab S12+ supports the S Pen, allowing users to write notes, annotate documents, draw and interact with compatible applications. This feature is useful for students, professionals and anyone who prefers handwriting for certain tasks.

The tablet also has an IP68 rating for dust and water resistance. Its specified rating covers immersion in up to 1.5 metres of water for 30 minutes under controlled test conditions. Water resistance can diminish over time, so users should not treat the rating as a guarantee against every type of liquid exposure.

The available colours are Gray and Silver.

Display

The Samsung Galaxy Tab S12+ features a 12.6-inch Dynamic AMOLED 2X display with a resolution of 1752 x 2800 pixels. It has a 16:10 aspect ratio, a pixel density of approximately 262ppi and a screen-to-body ratio of around 84.7%.

The display supports a 120Hz refresh rate, HDR10+ and a peak brightness of 1,600 nits. Its listed High Brightness Mode brightness is 1,000 nits.

The large screen provides enough space for reading, browsing websites, editing documents and using multiple applications. Its aspect ratio is also suitable for watching videos and working with documents.

The 120Hz refresh rate allows supported content and interface animations to appear smoother than on a conventional 60Hz display. HDR10+ support also benefits compatible videos by providing high-dynamic-range picture features.

The AMOLED panel delivers deep blacks and strong contrast, making the tablet suitable for watching films, viewing photographs and other activities where display quality matters.

Performance and Processor

The Galaxy Tab S12+ is powered by the MediaTek Dimensity 9500 chipset, built using a 3nm manufacturing process. Its octa-core CPU consists of one core running at up to 4.21GHz, three cores at up to 3.5GHz and four cores at up to 2.7GHz.

Graphics are handled by the Mali-G1 Ultra MC12 GPU, while 12GB of RAM provides memory for running applications and switching between tasks.

This hardware configuration is designed for productivity, multimedia, demanding applications and compatible games. Users can work with documents, browse the internet, stream videos and move between applications.

Actual performance depends on software optimisation, thermal conditions and the demands of each task. Benchmark testing would be needed to establish how the tablet compares with competing devices.

Camera Features

The Samsung Galaxy Tab S12+ has a 13MP rear camera with an f/2.0 aperture, autofocus and a 26mm-equivalent wide lens.

The rear camera features LED flash, HDR and panorama mode. It supports video recording at up to 4K resolution at 30 frames per second and 1080p at 30fps.

The rear camera can be useful for photographing documents, capturing reference images and recording everyday scenes. However, the tablet's size makes it less convenient for photography than a smartphone.

At the front, the device features a 12MP ultrawide camera with an f/2.4 aperture and a 120-degree field of view. The front camera supports HDR and records video at up to 4K at 30fps or 1080p at 30fps.

The ultrawide field of view helps include more people in the frame, depending on how the tablet is positioned. This makes the camera useful for video calls, online meetings and group conversations.

Battery and Charging

The Galaxy Tab S12+ comes with a 10,600mAh lithium-polymer battery and supports 45W wired charging.

The battery capacity provides a substantial power reserve for a tablet with a large display. However, actual battery life depends on screen brightness, refresh rate, network connectivity, applications and usage patterns.

The supplied specifications list battery endurance of 94 hours and 51 minutes under the EU energy label's testing methodology. This figure should not be interpreted as a guaranteed runtime under everyday conditions.

The 45W charging support allows the tablet to be charged using a compatible charger. The listed charging time to reach 100% is 95 minutes, although actual charging time can vary depending on the charger, cable, temperature and whether the tablet is being used while charging.

Software and Features

The Samsung Galaxy Tab S12+ runs Android 17 with Samsung's One UI 9 interface. It supports up to seven major Android OS upgrades, making long-term software support one of its key features.

One UI provides the interface for managing applications, notifications, settings and other Android features. The stated upgrade commitment is useful for people who intend to keep the tablet for several years, although update timing may vary by market and model.

Samsung DeX provides a desktop-style interface for supported productivity tasks. It can make working with documents and compatible applications more convenient, particularly when using suitable accessories and an external display.

The tablet also features an optical fingerprint sensor beneath the display for biometric authentication. Other listed sensors include an accelerometer, gyroscope, proximity sensor and compass.

S Pen support adds another way to interact with compatible applications, whether for handwriting, drawing or annotating files.

Storage and Memory

Samsung offers the Galaxy Tab S12+ with 256GB or 512GB of internal storage. Both configurations come with 12GB of RAM.

The tablet also supports microSDXC cards, allowing users to expand storage for photographs, videos, documents, downloaded files and other content.

The 256GB version may be sufficient for users who mainly browse the internet, stream content and work with documents. Those who store large video files, use creative applications or keep extensive offline media libraries may prefer the 512GB version.

Actual available internal storage will be lower than the advertised capacity because the operating system and pre-installed software occupy some space.

Gaming and Everyday Performance

The Dimensity 9500 chipset, Mali-G1 Ultra MC12 GPU and 12GB of RAM give the Galaxy Tab S12+ a hardware configuration suited to gaming and demanding applications.

Its 12.6-inch AMOLED display provides a large viewing area for games, while the 120Hz refresh rate allows supported games to display smoother motion. Actual frame rates depend on the game, graphics settings and software optimisation.

The tablet is also suitable for everyday activities such as browsing, messaging, video streaming, listening to music and editing documents. Its large screen can make reading and working with multiple applications more comfortable than on a smaller device.

The four-speaker stereo system provides built-in audio for films, games and music. Users who prefer wired headphones will need a compatible USB-C audio accessory or adapter because the tablet does not have a 3.5mm headphone jack.

For productivity, the S Pen and Samsung DeX provide additional ways to use the tablet for note-taking, document work and compatible desktop-style tasks.
