Following the rollout of its One UI 9.0 (Android 17) interface last month, Samsung is hitting the gas on software testing across a wide range of devices. According to the latest leaks, the Galaxy A56 is the next mid-range smartphone slated for the major OS upgrade.
Specifically, the first test build for the Galaxy A56—firmware version A566BXXUBDZFB—has officially surfaced on Samsung’s data servers. This move suggests the company's engineering team is diving into deep optimization, a step that should significantly cut down the wait time for users eager for the official release.
Unlike some of the massive overhauls seen in previous years, One UI 9.0 isn't a dramatic visual departure from One UI 8.5. Instead, the update doubles down on performance enhancements, deeper personalization options, and minor utility tweaks designed to smooth out everyday navigation.
The Galaxy A56 benefits from Samsung’s ambitious commitment to providing up to six major operating system upgrades. Having already bumped up to One UI 8.0 and 8.5, the device still has three major Android updates left in the pipeline—including the fast-approaching One UI 9.0.
