Samsung Galaxy A36 One UI 8.5 Beta Update: Internal Testing and Release Possibilities

The One UI 8.5 beta update, which was initially launched for the flagship Galaxy S25 series late last year, has recently begun expanding to various other high-end smartphones and tablets. While the rollout is gaining momentum for premium devices, Samsung has historically been more reserved with its beta programs for mid-range hardware. This has left many users wondering: will the popular Galaxy A36 actually receive a taste of the beta software before the final release?

Internal Testing Spotted: What the Firmware Reveals

Recent sightings on Samsung’s update servers indicate that the company has internally started testing the One UI 8.5 update for the Galaxy A36. A specific firmware version, A366EXXU8ZZD1, has been identified. In the world of Samsung development, the presence of the letter “Z” as the fourth character from the right typically denotes a test or beta build. This discovery has sparked excitement, as it suggests that a public beta release for this mid-range device could be on the horizon.

Expanding the Beta Horizon Beyond Flagships

Traditionally, Samsung’s beta programs were exclusive to the S and Z series. However, the strategy appears to be shifting. For the first time, Samsung has extended the Samsung firmware beta program to include the Galaxy S24 FE and the Galaxy S25 FE. This move signifies a broader inclusivity in their testing phases, which significantly increases the likelihood that top-tier Galaxy A series devices like the A36 and A56 might finally join the program.

While the evidence from the servers is compelling, it is important to remain cautious. Until Samsung officially opens the registration through the Samsung Members app, it remains unclear if the One UI 8.5 beta will be accessible to all users or remain an internal-only test for the Galaxy A36 and Galaxy A56.

Interestingly, the upcoming Galaxy A37 and Galaxy A57 are expected to be the pioneers for mid-range devices running One UI 8.5 straight out of the box. You can see the new software interface in action on these devices in the hands-on video provided below.
