Samsung's Galaxy Tab S12 series is a two-tablet launch with one shared brain and two very different bodies. The company's India announcement on 1 October 2026 put availability from 7 October, with the Plus at a 12.6-inch display and the Ultra at 14.6 inches. Wi-Fi weights are 553 g and 692 g respectively. Both run the Dimensity 9500 with 12GB RAM, 256GB or 512GB storage, and an in-box S Pen. Announced starting prices are Rs 129,999 for the Plus and Rs 149,999 for the Ultra; keyboard covers are separate at Rs 26,499 and Rs 27,999. Base tablet plus keyboard therefore calculates to Rs 156,498 and Rs 177,998 before any discount. Both ship on Android 17 with One UI 9, and Samsung states up to seven OS upgrades and security updates. Bundled trial and subscription app benefits are temporary. These are announcement figures, not guaranteed checkout prices.
This is a researched, specification-based comparison. It is expressly not a hands-on review: no unit was tested, no benchmark was run, and no retailer discount is assumed. The comparison combines Samsung's published specifications with practical checks Indian buyers can make before paying.
What the shared specifications actually settle
Because both tablets share the chip, memory, storage tiers, S Pen and software policy, the usual spec-sheet race ends early. You are not choosing between a fast tablet and a slow one. You are choosing a screen size and a weight, and paying roughly Rs 20,000 more at announcement for the larger panel.
Samsung states up to seven OS upgrades and security updates; that wording should not be casually converted into a guaranteed number of calendar years. Long-term software support is one part of the decision. Physical comfort and app compatibility also matter, especially if you intend to keep the device for several upgrade cycles.
Commuter reality versus desk reality
The 553 g Plus is the easier object to live with. Add a keyboard cover and you are carrying something closer to a thin laptop, but still within the range where a daily metro or office commute is realistic. The 12.6-inch panel is large enough for split-screen notes and reading without feeling like a tray table.
The 692 g Ultra is a different proposition. At 14.6 inches it behaves less like a tablet and more like a portable canvas. For a student annotating PDFs, a designer sketching, or anyone working from a fixed desk, the extra area is genuinely useful. For someone whose main use is a crowded commute, the weight and footprint become a daily tax.
Consider two hypothetical buyers with similar budgets. Buyer A travels daily and mainly reads, emails and takes notes. Buyer B draws and annotates large documents at a home desk. The Ultra's extra area may be useful to Buyer B while its larger footprint may inconvenience Buyer A. These are workflow-based judgments, not comfort findings from a tested unit.
Do the app and file-format check before calling it a laptop replacement
This is the step most buyers skip, and it matters more than the chip. Before treating either tablet as a laptop replacement, list the exact apps you use and the exact file formats you exchange.
- Does your primary work app exist as a proper Android app, or only as a browser version?
- Do the files you receive open and export correctly, with formatting intact?
- Do clients or institutions accept the format your tablet produces?
- Does your workflow need a desktop-only plugin, macro or driver?
If the answer to any of these is no, the tablet becomes a companion device, not a replacement. That is not a failure. It simply changes how much you should spend. For a companion device, ask which specific task would justify the Ultra premium rather than assuming that the biggest screen is necessary.
A purchasing worksheet for Indian buyers
Treat the announced prices as a starting line. Build a total-cost figure before you commit, and apply the same discipline you would to any large electronics purchase, such as checking configuration and total cost before buying a laptop. The logic transfers directly.
| Line item | Plus | Ultra |
|---|---|---|
| Announced tablet price | Rs 129,999 | Rs 149,999 |
| Keyboard cover | Rs 26,499 | Rs 27,999 |
| Calculated total | Rs 156,498 | Rs 177,998 |
Then ask three questions. First, does the keyboard cover belong in your budget at all, or will you mostly use the S Pen and a stand? Second, is 256GB enough once you account for offline video, design files and app data, or does 512GB remove a future problem? Third, are you relying on any bundled trial or subscription benefit? If so, price the tablet as though that benefit did not exist, because it is temporary.
Finally, verify the current price and configuration at the point of sale. Announcement pricing and launch-period offers can differ from what a given retailer charges on a given day. The Samsung India announcement is the correct reference for what was stated, not a promise about your checkout total.
Who should lean toward which model
Lean Plus if your day involves movement, if the tablet is a second device, or if you want the S Pen experience without the largest possible canvas. The saved money is better spent on storage or a protective case.
Lean Ultra if the tablet is your primary creative or study surface, if it mostly stays on a desk, and if you have already confirmed that your apps and file formats work. In that scenario the larger display earns its premium through daily use rather than novelty.
Buy neither on size alone. Shared headline specifications do not establish identical real-world performance; the deciding variables are weight, screen area and your verified workflow.
Conclusion
The Galaxy Tab S12 Plus and S12 Ultra are close cousins separated mainly by size, weight and about Rs 20,000 at announcement. For most Indian buyers who carry a tablet daily, the Plus is the more sensible default. The Ultra makes sense for desk-based drawing, annotation and study, provided you have checked your apps and file formats first. Confirm live pricing and configuration before paying, budget for the keyboard cover separately, and discount temporary app benefits. Choose the size that matches your routine, not the size that looks best on a specification sheet.
