Samsung Electronics has unveiled its latest Galaxy Tab S12 series, introducing the Galaxy Tab S12 Ultra and Galaxy Tab S12+ with upgraded performance, longer battery life, advanced Galaxy AI features and ultra-thin designs.

Samsung said the new tablets are designed to support productivity, learning, creativity and professional tasks, combining large displays with powerful hardware and AI-powered tools.

The tablets are powered by the MediaTek Dimensity 9500 processor and run Android 17 with One UI 9. Samsung says the new processor delivers up to 61 percent faster NPU processing, 19 percent faster CPU performance and 17 percent improved GPU performance compared with the Galaxy Tab S11 Ultra.

The new tablets also feature Samsung's latest Galaxy AI capabilities. Users can work with Samsung Notes, Note Assist, Gemini and other AI-powered tools while using the large display and S Pen. Multi Window allows users to divide the screen into up to three sections for multitasking.
