Galaxy Tab S12 tablet arrives as Samsung’s new premium Android tablet family, led by the 14.6-inch Galaxy Tab S12 Ultra and the 12.6-inch Galaxy Tab S12+. Announced on September 30, the range combines thinner bodies, Dynamic AMOLED 2X displays, a 3-nanometre processor and an included S Pen. Sales are due to begin in selected markets on October 7, while exact prices, storage options and mobile-network versions will vary by country.
Two sizes for different kinds of work
The Ultra model uses a 14.6-inch screen and a body that is 5.1 millimetres thick. The S12+ reduces the display to 12.6 inches, making it easier to carry while still providing enough space for split-screen work. Both panels support refresh rates up to 120Hz, a claimed peak brightness of 1,600 nits and Samsung’s Vision Booster system for adapting the picture to ambient light.
Those numbers matter most when the tablet is used near a window, outdoors or with several apps visible at once. A large screen can improve document review, note-taking and timeline-based creative work, but it also changes portability. Buyers should decide whether they need the Ultra’s workspace or the more manageable dimensions of the Plus model instead of assuming that the largest display is automatically the best choice.
S Pen is included
Samsung includes the S Pen in the box with both models. That is an important practical difference from devices where the stylus is sold separately. The pen can be useful for handwritten notes, marking PDFs, drawing and precise selections, although professional artists should still check whether their preferred applications support the required file formats, brush engines and colour-management workflow.
A keyboard remains a separate part of the wider productivity equation. Users hoping to replace a laptop should test the keyboard layout, trackpad, external-display behaviour and file exchange with colleagues before committing. Android multitasking has improved, but the availability and quality of desktop-class applications still determines whether a tablet can replace a notebook in a specific job.
Performance, cooling and battery life
The tablets are powered by MediaTek’s 3nm Dimensity 9500. Samsung claims up to 61 percent faster NPU performance, a 19 percent CPU improvement and a 17 percent stronger GPU compared with the Tab S11 Ultra. These are manufacturer measurements rather than independent benchmarks, so real gains will depend on the application, thermal conditions and power profile. A new 3D vapour chamber is intended to keep performance stable during longer workloads.
Don’t miss this
The Galaxy Tab S12 Ultra carries an 11,600mAh battery, while the S12+ uses a 10,600mAh unit. Both support 45W charging. Samsung quotes up to 23 hours of video playback for the Ultra and 21 hours for the Plus under its own test conditions. Screen brightness, cellular use, background synchronisation and demanding creative software can produce very different results in everyday use.
Software support is the longer-term advantage
The Galaxy Tab S12 family launches with Android 17 and One UI 9. Samsung promises up to seven generations of operating-system upgrades and security updates. For schools, businesses and people who keep a tablet for several years, that commitment may be more valuable than a short-lived benchmark lead because it reduces the risk of losing security support while the hardware remains usable.
Samsung DeX remains central to the productivity pitch, and the large display should help with several windows at once. Galaxy AI features cover writing, notes and content organisation, but availability can depend on language, account, network access and future service terms. Buyers should therefore judge the device on its hardware and confirmed application support first, treating cloud-based AI features as an additional benefit rather than the only reason to upgrade.
Galaxy Tab S12 tablet: what to check
IP68 resistance provides protection against water and dust under defined laboratory conditions, but it does not make the tablet suitable for diving or permanent use in wet environments. Prospective buyers should also confirm local pricing, whether a charger is included, keyboard cost, available RAM and storage, 5G support and compatibility with the professional tools they use every day.
The Galaxy Tab S12 tablet looks like a measured upgrade for people who value a large OLED display, pen input and long software support. Its real value will depend on regional pricing and whether Android applications match the buyer’s workflow. Students and professionals should test multitasking, export formats, backup options and accessory costs.
