Galaxy A55 One UI 9.0 Beta: Android 17 Firmware Appears on Samsung Servers

Samsung’s highly anticipated One UI 9.0 update, built on the upcoming Android 17 architecture, appears to be inching closer to a broader public release. Following initial development whispers in June 2026, fresh evidence suggests that the popular mid-range Galaxy A55 will be one of the next devices to receive the beta treatment.

A new test firmware for the handset has been officially spotted on Samsung’s internal servers. Identified as firmware version A556SKSUAZZH5 (first flagged by industry tipster Tarun Vats), the build is a strong indicator that the South Korean tech giant is actively preparing to launch a public One UI 9.0 beta program for Galaxy A55 users.

A Slower-Than-Expected Rollout

The deployment of One UI 9.0 has been a methodical, tightly controlled process. Samsung initially unveiled the custom interface via a limited beta phase exclusively for its flagship Galaxy S26 series. The stable version finally made its grand debut over a month ago, shipping out of the box with the company’s latest premium foldables, the Galaxy Z Fold 8 and Galaxy Z Flip 8.

The Android 17-based update promises a wealth of new UI customization options, enhanced performance, and deep system-level tweaks. However, the broader rollout strategy has left the community somewhat impatient.

Industry watchers and consumers alike largely expected Samsung to rapidly expand the beta program to its mid-tier devices and older flagships shortly after the foldable launch. Despite those expectations, official communication regarding the wider One UI 9.0 rollout remains conspicuously absent.

For now, the appearance of this firmware on official servers provides a glimmer of hope to the mid-range market. Galaxy A55 owners eager to test drive Android 17 should keep a close eye on the Samsung Members app, as official beta recruitment could be just around the corner.
