While the public beta for One UI 8.5 remains exclusive to the Galaxy S25 series, Samsung’s development efforts are far more extensive. The company is actively testing the new software internally on a wide range of devices, and builds have been spotted on its servers for dozens of phones and tablets.
These internal builds are not available for public download or testing. Their presence on Samsung’s servers simply confirms that development for these specific models is underway. If your device is on the list below, it means Samsung is working on bringing One UI 8.5 to it, though the public rollout may still be months away.

This list is expected to grow as we approach the stable release, which is anticipated to debut with the Galaxy S26 series in February.
For users whose devices aren’t listed, eligibility for One UI 8.5 is still likely if the device received the previous One UI 8.0 update. This internal testing phase is a crucial step toward delivering the stable version. We expect the stable rollout to older devices to begin in earnest after the Galaxy S26 series launch, likely stretching through the spring and summer.
