Samsung Galaxy Tab S12 Ultra

The Samsung Galaxy Tab S12 Ultra combines a large-format display, next-generation performance, and advanced productivity tools in a surprisingly slim design. It is made for studying, working, creating content, and enjoying entertainment with an experience close to that of a computer, enhanced by Samsung DeX, Galaxy AI, and the included S Pen.

This description applies to the different versions of the Galaxy Tab S12 Ultra. Mobile connectivity, weight, and certain network-related features may vary between the Wi-Fi and 5G models.

Screen

Its large 14.6-inch Dynamic AMOLED 2X display offers WQXGA+ resolution of 2960 × 1848 pixels and a refresh rate of up to 120 Hz. The result is a spacious, smooth, detailed viewing experience for working with multiple apps, drawing, editing content, or playing video.

The display reaches up to 1,600 nits peak brightness and 1,000 nits in HBM mode, while Vision Booster adjusts the image to suit lighting conditions for easier viewing indoors and outdoors.

Performance

The 3 nm MediaTek Dimensity 9500 processor delivers the power needed for demanding apps, content creation, gaming, and advanced multitasking. Its octa-core CPU is complemented by a 3D vapor chamber, designed to dissipate heat and maintain stable performance during extended workloads.

Android 17 and One UI 9 include productivity tools and Galaxy AI features. Multi Window lets you split the screen into several areas, while Samsung DeX offers a desktop interface with up to four workspaces.

S Pen and productivity

The S Pen is included in the box and lets you write, draw, take notes, and make precise edits with low latency. Its integration with Samsung Notes and creative apps turns the large screen into a flexible workspace.

It is also compatible with apps optimized for productivity, illustration, note-taking, and editing. Some apps or advanced features may require a subscription, a compatible account, or an Internet connection.

Cameras and multimedia

The rear camera combines a 13 MP main sensor with an 8 MP ultra-wide camera, as well as autofocus and flash. It can record video in UHD 4K resolution at 60 fps. The front features a 12 MP ultra-wide camera, ideal for video calls, meetings, and online classes.

The four-speaker system with four-channel spatial audio delivers a spacious, immersive sound experience for movies, music, games, and calls.

Battery and charging

The 11,600 mAh battery provides up to 23 hours of wireless video playback, according to tests conducted by Samsung. It supports up to 45 W Super Fast Charging 2.0 and the USB Power Delivery standard.

The power adapter is not included. To take advantage of fast charging, use a compatible USB-C charger, sold separately.

Design and durability

At just 5.1 mm thick, the Galaxy Tab S12 Ultra combines a large screen area with a slim, portable design. Its structure uses enhanced Armor Aluminum for greater durability in everyday use.

The tablet and the included S Pen have IP68 water and dust resistance certification. This protection has been tested under laboratory conditions and may decrease with normal wear; use of the device at beaches or pools is not recommended.

Connectivity

All versions feature Wi-Fi 7, Bluetooth 6.0, USB-C, and GPS, GLONASS, Galileo, BeiDou, and QZSS positioning systems. Wi-Fi connectivity operates on the 2.4, 5, and 6 GHz bands.

The family is available in Wi-Fi and 5G variants. The 5G versions add mobile connectivity and Dual SIM support via a physical card and eSIM, while the Wi-Fi models do not connect to mobile networks.
