Samsung Galaxy Tab S12 Series Leaks Reveal Full Specs, Dimensity 9500 Power and October 7 Launch

 

Quick Takeaways

• Galaxy Tab S12 Plus and Ultra leaks point to flagship hardware, including MediaTek's Dimensity 9500, 120Hz Dynamic AMOLED 2X displays and S Pen support.

• The Tab S12 Ultra is expected to remain the larger productivity-focused model, with a 14.6-inch display, up to 16GB RAM and up to 1TB storage.

• October 7, 2026 is the key date to watch, although Samsung's final specifications, pricing and availability still need official confirmation.

Samsung's next generation of premium Android tablets is shaping up to be one of its most closely watched launches of 2026. A growing collection of leaks has revealed detailed information about the Galaxy Tab S12 Plus and Galaxy Tab S12 Ultra, including their displays, processors, cameras, batteries, storage options and expected software.

The biggest changes may not be on the outside. Samsung is reportedly preparing both tablets with MediaTek's Dimensity 9500, while the Plus model could receive a larger battery and lighter body. The Ultra, meanwhile, is expected to retain its huge 14.6-inch display while expanding its memory and storage options.

Perhaps the most interesting change is the apparent absence of a standard Galaxy Tab S12 model. If the reports are accurate, Samsung could be concentrating its flagship tablet strategy entirely on the Plus and Ultra.

The specifications, pricing and launch information discussed here remain based on leaks and reports available in September 2026.

Launch Date: October 7 Is All but Official

According to multiple credible leaks, Samsung will unveil the Galaxy Tab S12 Plus and Tab S12 Ultra on October 7, 2026

Both tablets are expected to ship with One UI 9.0 based on Android 17 out of the box, with rumours pointing to up to seven years of software support. Colour options are reportedly limited to Silver and Grey for both models

The timing makes strategic sense, too. An early-October unveiling puts the tablets on shelves well before the holiday shopping rush, giving Samsung a premium productivity play to market alongside its foldables and the upcoming Galaxy S27 wave.

No Base Model: A Premium-Only Lineup

Here's the surprise that changes the math for many buyers: there is no standard Galaxy Tab S12. Earlier reports hinted at a three-model range, but the latest full specification leaks consistently mention only two devices:

• Galaxy Tab S12 Plus — the new entry point

• Galaxy Tab S12 Ultra — the flagship heavyweight

The affordable base model that has long served as the gateway to Samsung's tablet ecosystem is gone. Want in on the S12 generation? You'll be paying Plus-tier money from the very first click.

It's a bold, divisive move. On one hand, it streamlines the lineup and pushes the brand further upmarket, closer to the laptop-replacement positioning Samsung has chased for years. On the other, it leaves the midrange tablet space wide open for rivals like Xiaomi, OnePlus, and Lenovo to swoop in with compelling alternatives at half the price.

Leaked Specifications: Tab S12 Plus vs. Tab S12 Ultra

The leaked spec sheets point to an incremental but solid refresh, headlined by a new chipset, a bigger battery on the Plus, and expanded memory tiers on the Ultra.

Final configurations may vary; figures are based on current leak information ahead of the official announcement.

The Headline Upgrades

MediaTek Dimensity 9500 power across the board. This marks the third consecutive generation of Samsung flagship tablets running MediaTek silicon, following the Dimensity 9300+ and 9400+. Built on an advanced 3nm process with a prime core clocked at up to 4.21GHz, early Geekbench listings show roughly 2,424 single-core and 8,446 multi-core scores. Perhaps more importantly for a tablet form factor, the chip's thermal efficiency and generous heat headroom should translate into strong sustained performance for multitasking, creative work, and gaming, plus the neural processing muscle behind an expanded on-device Galaxy AI experience.

A bigger battery for the Plus. The S12 Plus reportedly moves from 10,090mAh to 10,600mAh, a practical ~5% bump that genuinely matters on a device designed for all-day productivity and travel. The Ultra keeps its 11,600mAh cell, so any endurance gains there will depend on chipset efficiency and software optimisation.

Up to 16GB RAM and 1TB storage. The Ultra is expected to top out at a full terabyte of UFS 4.0 storage paired with 16GB of RAM, laptop-class specs on paper. And in a refreshing counter-trend, both models retain microSD expansion up to 2TB, a feature many rival tablets have abandoned entirely.

Lighter where it counts. The Plus sheds weight to approximately 555g (down from 571g), making extended handheld reading and sketching noticeably more comfortable. The Ultra stays put at 693g, with dimensions virtually identical to its predecessor, notch, magnetic S Pen strip, and all.

Design and Accessories: Familiar Shells, Serious Productivity Play

If you were expecting a radical redesign, pump the brakes. Leaked renders and third-party rugged case listings, complete with dedicated S Pen slots, suggest the S12 series sticks with the familiar formula: slim bezels, a clean flat-frame aesthetic, and the Ultra's signature display notch.

The accessory pipeline is where things get interesting:

• Book Cover Keyboard Slim — a lightweight, single-piece magnetic folio for casual typing and note-taking

• Pro Keyboard — the premium two-piece option with a trackpad, backlit keys, and a laptop-like hinge for serious DeX workflows

• Rugged case options — a nod to field-work and education crowds, already listed by established case makers

This keyboard push confirms Samsung's positioning: these aren't just media-consumption slates. They're laptop challengers, and the accessories are priced and designed accordingly.

The Price Problem: Memory Inflation Meets the Tablet Market

Now for the elephant in the room. Leaked pricing puts the Tab S12 Plus at around €1,299 (~$1,199) and the Tab S12 Ultra at roughly €1,539 (~$1,399), already a noticeable jump over previous generations, with increases of 17% to 24% reported across equivalent storage tiers. And the fully loaded Ultra with 16GB RAM and 1TB storage? Rumoured to approach $2,000. That's premium laptop territory.

Why the steep climb? According to industry watchers, the culprit is the AI memory crunch. Global demand for RAM and storage to feed AI data centres has exploded, prompting memory suppliers to redirect production toward high-margin server chips. The result: DRAM and NAND flash prices have surged industry-wide, and consumer devices are absorbing the hit. Memory's share of a device's total component cost has reportedly doubled or even tripled over the past year, and tablets, which carry more RAM and storage than phones, are feeling it acutely.

There's a delicious irony here: Samsung is the world's largest memory manufacturer, meaning its semiconductor division is profiting handsomely from the very shortage squeezing its own tablet margins. Dropping the base model in the same cycle starts to look less like coincidence and more like a coordinated response to rising component costs.

How to Prepare for the Galaxy Tab S12 Launch

Planning to pick one up on day one? Here's the smart way to do it:

1. Save the date. Keep October 7 free and follow Samsung's official channels for the announcement stream and regional availability details.

2. Audit your trade-in value now. Trade-in quotes typically drop once a new generation is officially announced, so get a valuation on your current tablet before launch day.

3. Pick your model wisely. The Plus suits portability, note-taking, and everyday productivity; the Ultra's 14.6-inch canvas is a genuine laptop alternative for split-screen multitasking and creative work.

4. Compare storage tiers early. With memory prices climbing, higher configurations may jump in price faster than usual, and remember, a 2TB microSD card may be the value play over paying for internal storage.

5. Shortlist your accessories. Decide between the Slim and Pro keyboards ahead of time; launch bundles usually shave money off buying separately.

6. Set it up on arrival. Use Smart Switch to migrate your data, install day-one updates under Settings > Software Update, sign in to your Samsung account to unlock Galaxy AI features, and explore DeX mode to turn the tablet into a desktop-style workstation.

Analysis: What the Tab S12 Leaks Really Tell Us

The MediaTek era is here to stay. The Dimensity 9500 in both models cements Samsung's shift away from Snapdragon in its tablets. Beyond supply-chain diversification, it signals genuine confidence in MediaTek's flagship silicon and in a tablet chassis with superior thermal headroom; sustained performance could be where this chip truly shines.

The annual upgrade debate is getting louder. Here's the uncomfortable truth: the Tab S11 generation arrived barely a year ago, and the S12's changes- a new chip, a slightly bigger battery on the Plus, more storage- read like a routine refresh rather than a leap. Tablets aren't phones; most buyers keep them for four to five years, and last year's model remains enormously capable. For Tab S11 owners, this launch is easy to skip. For everyone else coming from older hardware, it's a strong starting point, just don't expect a revolution.

The competition is watching closely. Apple will be monitoring the $2,000 Ultra's reception; it plays directly into iPad Pro territory, and the keyboard-and-stylus productivity battle is now head-to-head. Meanwhile, Xiaomi, OnePlus, and Lenovo emerge as the quiet winners: Samsung vacating the affordable flagship tier hands them an open lane in a segment where they've been gaining real momentum. And with tablet prices brushing against Windows ultrabooks, Samsung must convince buyers that Android is a first-class productivity platform, not just a media machine.

The Bottom Line

The Galaxy Tab S12 leaks paint a clear picture: Samsung is going bigger, pricier, and more AI-centric, and leaving the affordable tier behind. You're getting flagship Dimensity 9500 power, a larger battery on the Plus, up to 16GB RAM and 1TB storage on the Ultra, 2TB expandable storage, an included S Pen, IP68 durability, and up to seven years of updates, all wrapped in an October 7 launch that's essentially official.

The bigger story, though, extends beyond one product. The AI memory crunch is inflating hardware prices across the board, and the Tab S12 series may be one of the first tablets where that pressure is fully visible on the price tag. Whether buyers will accept a $2,000 tablet, and whether hungrier rivals fill the midrange vacuum Samsung leaves behind, will define the next chapter of the Android tablet market.

One thing's certain: October 7 just became a very interesting date for anyone who cares about tablets. Until Samsung confirms the final pricing and availability, treat these details as strong rumours, and if you're upgrading, keep a close eye on those discounted Tab S11 deals. They might just be the smartest buy of the season.
