Samsung Galaxy Tab S12 Plus and Ultra Launch Date Targets September
A tipster with a decent track record has told SamMobile today that Samsung plans to announce the Galaxy Tab S12 Plus and Tab S12 Ultra in September 2026, placing the Samsung Galaxy Tab S12 Plus and Ultra launch date roughly two months out. That claim lands on top of independent projections from Trusted Reviews and Notebookcheck, both of which flagged late summer 2026 five months ago based on Samsung's previous release patterns. Three outlets arriving at the same window by different routes is the strongest convergence this story has produced so far.
The secondary detail: no standard Tab S12 has appeared in the cited IMEI database listings and reports so far. That absence, consistent across the sources reviewed here, is what Trusted Reviews suggests may indicate Samsung skipping a compact flagship again.
Samsung Galaxy Tab S12 Plus and Ultra launch date: why September keeps resurfacing
The February window estimates were pattern-based, not sourced. Trusted Reviews and Notebookcheck both noted that the Galaxy Watch 9 series and foldables were expected at a dedicated Galaxy Unpacked event earlier in the summer, with the tablets arriving as a separate wave afterward. Notebookcheck was specific: the Galaxy Watch 9 and Galaxy Watch Ultra 2 were expected to debut alongside the Galaxy Z foldables at that same Unpacked event. That structural separation is what made late summer a logical inference rather than a guess.
What today's SamMobile report adds is a specific month. The February estimates could only say "late summer"; SamMobile now puts September on the timeline directly.
What none of this resolves: whether Samsung announces and ships simultaneously, whether there will be a standalone event for the tablets, and whether September means early or late in the month. No event invitations or regulatory clearances beyond the initial model-number database sightings have surfaced. Samsung has not confirmed anything publicly.
The missing compact model, two generations running
IMEI database listings that emerged in early February showed two Galaxy Tab S12 models under the numbers SM-X846 and SM-X946, which align with Samsung's established naming convention for Plus and Ultra variants, according to both Trusted Reviews and Notebookcheck. No smaller companion model appeared alongside them.
SamMobile notes that Samsung launched only the Tab S11 Plus and Tab S11 Ultra last year. Trusted Reviews draws the same parallel to the Tab S10 lineup, where a compact flagship was also absent. An absence in early database listings isn't a confirmed cancellation; a smaller model could surface later or ship separately. But two consecutive generations without one in the early checks is the current picture.
As Trusted Reviews put it, the early listings suggest "smaller flagships may no longer be part of the plan." Anyone waiting specifically for a premium Samsung tablet in a more portable size should factor that in, with the caveat that the evidence here is absence rather than confirmation.
What the rumored specs suggest about who these tablets are for
Keep in mind that the spec details below come almost entirely from a single SamMobile report published today. The timing and lineup evidence has cross-source support; these hardware specifics do not. Treat them as provisional until additional sources or Samsung itself corroborates them.
Screen size signals intent. The Tab S12 Plus is reportedly coming with a 12.4-inch display; the Ultra is said to measure 14.6 inches. Both could use OLED panels with up to 120Hz variable refresh rate, per SamMobile. Trusted Reviews noted earlier this year that the Ultra in particular is expected to continue pushing Samsung's tablet hardware "closer to laptop territory," with expansive displays and high-end internals. The Plus, by that framing, would be the slightly more manageable alternative, but still firmly in the large-tablet camp.
On internals, SamMobile reports both devices are expected to be powered by MediaTek's 3nm Dimensity 9500 processor, with 12GB of RAM and at least 256GB of base storage. A microSDXC card slot is also reportedly included. Front cameras are said to be 12MP units capable of 4K video, housed in a punch-hole cutout. Both tablets are expected to ship with Android 17-based One UI 9.0, though that detail carries the same single-source caveat as everything else in this section.
What the announcement will still need to answer
Pricing is entirely absent from the current reporting. Without even a rough range, the Tab S12 Plus and Ultra can't be meaningfully weighed against the iPad Pro, Surface Pro, or Samsung's own previous models. Price is ultimately what determines whether the productivity positioning holds up.
Battery information is partial. The Tab S12 Plus is rumored to carry a 10,500–10,600mAh cell, per SamMobile, but no capacity figure has surfaced for the Ultra. For a 14.6-inch device aimed at extended work sessions, that's a notable gap.
The accessory and software story is largely dark. S Pen inclusion or accessory status, keyboard cover compatibility, charging speeds, port configuration, DeX updates, and any AI-specific features haven't appeared in any of the cited reporting. For tablets positioned as productivity tools, those details often carry more weight in a buying decision than the chipset number.
Between now and a potential September announcement, the signals worth watching are FCC or regulatory filings beyond the initial IMEI sightings, benchmark appearances that would independently confirm the Dimensity 9500, accessory-line leaks, and any Samsung event invitations. A formal announcement would also clarify whether Samsung ships immediately or staggers availability by region, something the current evidence doesn't address.
The September announcement, if it comes, will settle most of the open questions. Whether the Galaxy Tab S12 Plus and Ultra make a compelling case against the iPad Pro and Surface Pro will depend almost entirely on the details that haven't leaked yet: price, accessories, and the software experience. The hardware ambition is clear enough from what's been reported. The value case isn't, yet.
