A certification image has provided an early look at Samsung's unannounced Galaxy Tab S12 Plus. The photo shows a familiar Galaxy Tab design, while separate software findings suggest Samsung is preparing support for MediaTek's flagship Dimensity 9500 processor and several AI-powered image tools.
Neither the processor nor a release date has been confirmed. The available evidence shows that the tablet is moving through regulatory channels and that Samsung is testing software for the Dimensity 9500, but it does not directly connect the chip to the Galaxy Tab S12 Plus.
Regulatory listings identify SM-X840 as the Wi-Fi model and SM-X846B as the 5G version. Samsung has not announced the Galaxy Tab S12 lineup, pricing or final specifications.
What the Galaxy Tab S12 Plus image confirms
The certification image appeared in South Korea's Safety Korea database after the tablet also surfaced at the Bureau of Indian Standards.
It shows a physical tablet with uniform bezels and a front camera positioned along the landscape edge. The camera remains inside the bezel rather than occupying a notch or punch-hole cutout.
The image does not reveal the processor, display technology, battery, cameras, memory or storage. Its main value is confirming that a Galaxy Tab S12 Plus unit has entered at least one regulatory process.
The filings also do not establish when Samsung will release the tablet. An August or September 2026 debut has been suggested based on the timing of its earlier appearance in the GSMA IMEI database, but that remains an estimate.
A battery upgrade may be coming
A March 16 SamMobile report linked the Galaxy Tab S12 Plus to batteries carrying the model numbers EB-BX846AAE and EB-BX846AAY. Both reportedly have a rated capacity of 10,392mAh.
Samsung could advertise a slightly higher typical capacity, possibly around 10,500mAh or 10,600mAh. Rated and typical capacities are measured differently, so the final marketed figure may not match the certification value exactly.
That would represent a modest increase over the 10,090mAh typical battery in the Galaxy Tab S10 Plus. Samsung skipped the Plus size in the Galaxy Tab S11 generation, releasing standard and Ultra models instead.
No reliable information has established the Tab S12 Plus' charging speed, display size or other final hardware specifications. Claims that it will retain a 12.4-inch OLED display, 45-watt charging and familiar storage configurations remain predictions based largely on previous Plus models.
The Dimensity 9500 evidence is still indirect
A May 14 AI Core app teardown found the identifier MT6993 in Samsung's software. MT6993 is MediaTek's designation for the Dimensity 9500.
The code does not name a tablet or any other device. It shows that Samsung is developing software support for the processor, while its connection to the Galaxy Tab S12 series remains an informed guess.
That possibility is credible because Samsung already uses MediaTek processors in its premium tablets. The Galaxy Tab S11 and S11 Ultra launched in September 2025 with the Dimensity 9400 Plus. Samsung also used MediaTek chips in the preceding Tab S10 generation, so adopting the Dimensity 9500 would continue an existing strategy rather than mark a supplier switch.
MediaTek lists an all-big-core CPU, updated graphics, a dedicated neural processing unit, LPDDR5X memory support, UFS 4.1 storage and Wi-Fi 7 among the Dimensity 9500 specifications.
The processor's performance in a future Samsung tablet cannot be predicted from its specification sheet alone. Cooling, power limits, memory and software optimization can substantially affect the results.
In an April 2026 chipset comparison, Android Authority found that a Dimensity 9500-powered phone trailed a Snapdragon 8 Elite Gen 5 model in CPU tests but posted stronger initial graphics results and ran substantially cooler during stress testing. Both devices eventually throttled, and the results cannot be applied directly to an unannounced Galaxy tablet.
Samsung is testing new AI image tools
The AI Core code also contains references to four image-related functions:
FEATURE_WALLPAPERFEATURE_INOUT_PAINTINGFEATURE_GEN_EDIT_ON_DEVICEFEATURE_HARMONIZATION_ON_DEVICE
The names suggest AI-generated wallpapers, generative editing, image expansion and image harmonization. Inpainting generally replaces or generates content within a selected area, while outpainting extends an image beyond its original boundaries. Image harmonization can adjust lighting, color and contrast to make inserted objects fit a scene more naturally.
None of these tools is confirmed for the Galaxy Tab S12 series. App teardowns examine unfinished code, and features found during development may be changed, delayed or removed before release.
The identifiers also do not prove that every stage of each tool will run locally. Some features may still require an internet connection, cloud processing or a Samsung account.
More local processing could improve response times, preserve limited functionality without a connection and reduce the amount of image data uploaded to a server. Those benefits will depend on how Samsung implements the tools.
The biggest details remain unknown
A benchmark, firmware file or regulatory record connecting MT6993 directly to a Galaxy Tab S12 model number would provide much stronger evidence for the processor claim.
Samsung has not confirmed the Plus model's display, refresh rate, battery capacity, charging speed, cameras, memory, storage, S Pen support, AI features, price or release date.
The certification image is credible evidence that the Galaxy Tab S12 Plus is progressing toward release. The Dimensity 9500 and its associated AI tools are more significant potential upgrades, but they remain unconfirmed for this specific tablet.
