Samsung began rolling out its One UI 8.5 update on May 6, and by May 11 it was set to reach most devices globally. The software brings family-sharing improvements, stronger security measures and generative AI tools to supported Galaxy phones.
That timing is why Galaxy owners are checking compatibility now. The update first appeared on the newest Galaxy models, including the Galaxy 26, S26+ and S26 Ultra, and Samsung says it will move to other phones from there. One writer said they already had One UI 8.5 downloaded and installed on a Galaxy S25 Ultra, showing the rollout is not just announced — it is already landing on devices in the field.
For older phones, the appeal is more specific. One UI 8.5 brings Galaxy S26 features to earlier models, including call screening, which was first added to the S26 series. On supported phones as far back as the Galaxy S23, the AI assistant can take unknown calls, ask what the caller wants and produce a transcribed summary that can be checked later.
The update matters because it is not limited to the latest hardware. Samsung launched One UI 8.0 on Android 16, but One UI 8.5 is based on Android QPR2, and some devices that can run Android 16 may still miss out. The Galaxy S23 and Z Fold 5 series were first available in 2023, while Samsung has not officially acknowledged whether several 2022 models — including the Galaxy S22, Galaxy S22+, Galaxy S22 Ultra, Galaxy Z Fold 4 and Galaxy Z Flip 4 — will get the new software.
That leaves a familiar gap between what Samsung is promising broadly and what it has confirmed model by model. The company introduced a seven-year update policy with the Galaxy S24 launch, and it tells users to check the Samsung Members App to see which devices are compatible, a useful step when some phones may get the update later than others and a select few may not get it at all.
The clearest takeaway for Galaxy owners is that the rollout has started, the global push is underway, and the list of eligible phones is still being drawn in public. For anyone waiting on a specific model, the next move is not a new feature demo. It is Samsung filling in the missing names.
