Samsung is set to unveil Galaxy Tab S10 series soon! While the exact launch date is currently unknown, we expect Tab S10 series to be introduced in 2025. Earlier rumors suggested that the Galaxy Tab S10 Plus will feature MediaTek Dimensity 9300 chipset. Now, the Tab S10 series has appeared on Samsung’s OTA server, revealing that One UI testing has already begun.
Android Headlines team spotted Galaxy Tab S10 Plus and Tab S10 Ultra on Samsung’s OTA server. Galaxy Tab S10 Plus has the model number of SM-X828x, while Tab S10 Ultra is appeared as SM-X926x. The “x” in the model number represents the region code.


Galaxy Tab S10 Plus appeared on Samsung’s OTA server with the build number (X828USQUAXF5/X828UOYNOAXF5/X828USQUOAXF5). The Galaxy Tab S10 Ultra made its first appearance with the build number (X926BXXUOAXE6/X926BOXMOAXE6/X926BXXUOAXE6). These build numbers actually confirm the devices’ model numbers as SM-X926B and SM-X828U. Note that the “U” is for the US variant, while the “B” indicates that the model will be available globally.


They also managed to find Galaxy Tab S10 Ultra’s SM-X926C and SM-X926N model numbers, which confirms the device’s availability in China and Korea. Notably, there is no One UI build for the regular Galaxy Tab S10 yet. This is likely because the Tab S10 series is slated for a 2025 release. We anticipate that Galaxy Tab S10 series will debut alongside the Galaxy S25 series in Q1 2025.
