The Tech TL;DR:

• Hardware Scope: The upcoming lineup features two flagship configurations—the 12.4-inch Tab S12+ and the 14.6-inch Tab S12 Ultra—identified across multiple regional model numbers.
• Deployment Timeline: Industry tracking points toward a second-half 2026 launch window, aligning with Samsung’s historical autumn hardware release cadence.
• Connectivity Tiers: Google Play Console logs cleanly differentiate between Wi-Fi-only builds and global 5G cellular variants.

Model Numbers and Regional Connectivity Configurations

According to the Google Play Console database entries cited by PhoneArena, the new hardware variations are segregated by distinct codenames and regional designations. For the Galaxy Tab S12+, the standard Wi-Fi-only configuration carries the codename “gts12pwifi” alongside the model number SM-X840. Meanwhile, the 5G cellular variants are categorized under the codename “gts12p” with regional designations including SM-X846B, SM-X846E, and SM-X846N. The US-bound cellular variant, designated as the SM-X848U, has also surfaced separately in Federal Communications Commission (FCC) documentation.

The Galaxy Tab S12 Ultra follows an identical architectural taxonomy across its hardware iterations. Its Wi-Fi-only build uses the codename “gts12uwifi” and model number SM-X940. The 5G cellular variants adopt the codename “gts12u” along with model numbers SM-X946B and SM-X946N, which previously appeared in South Korean regulatory filings and India’s Bureau of Indian Standards (BIS) registry.

Hardware Specifications and Underlying Silicon Rumors

While Google’s directory listings focus primarily on verifying software compatibility, API levels, and display density metrics, early supply chain disclosures indicate significant hardware updates beneath the chassis. Industry intelligence reports suggest that the Tab S12 family may incorporate MediaTek’s flagship Dimensity 9500 system-on-chip, marking a notable shift in processing architecture for Samsung’s premier Android tablet tier.

Regarding physical dimensions and power delivery, supply chain data indicates that the Tab S12 Ultra will maintain its expansive 14.6-inch Dynamic AMOLED 2X panel backed by an 11,600mAh battery cell. Concurrently, the Tab S12+ is expected to preserve the form factor of its predecessor by retaining a 12.4-inch display panel paired with a 10,600mAh battery.

Launch Cadence and Enterprise Deployment Considerations

Samsung previously confirmed during an earnings report that it intends to commercialize its next-generation premium tablet family in the second half of 2026. Because the preceding Tab S11 lineup debuted in September, hardware analysts anticipate a similar late-summer announcement window, potentially coinciding with the IFA trade show in Berlin.
