Samsung finally brings missing Galaxy AI features to the Galaxy S25 series

At a glance:

• Samsung rolls out the One UI 8.5 June 2026 update for the Galaxy S25 series in South Korea.
• The update adds the previously missing AI features: Prioritise Notifications, Summarise Notifications, and File Summaries.
• An international rollout covering North America, Europe and India is expected within the next week.

What the update adds

Samsung’s One UI 8.5 June 2026 build (S938NKSUACZF1) finally delivers three AI‑driven capabilities that were omitted from the earlier One UI 8.5 release for the Galaxy S25 series. The features are:

• Prioritise Notifications – re‑orders the notification shade so that the most important alerts appear at the top, reducing clutter.
• Summarise Notifications – condenses long notification threads into a concise summary, making it easier to scan multiple messages.
• File Summaries – generates on‑device AI summaries of PDF and TXT documents, letting users skim content without opening the full file.

These tools were first introduced on the Galaxy S26 and have now been back‑ported to the S25, aligning the older flagship with Samsung’s latest AI roadmap.

Rollout details and size

The rollout began on June 1, 2026, in Samsung’s home market of South Korea, following the company’s usual pattern of a domestic launch before expanding abroad. Early adopters reported that the update package is unusually large for a routine security‑patch bump, reflecting the inclusion of the new AI models and on‑device inference engines.

The update also raises the Android security patch level to June 2026, ensuring the device receives the latest vulnerability fixes alongside the new features. Users can verify the installation by checking the build number in Settings → About phone.

International expansion timeline

While the South Korean rollout is already underway, Samsung has signaled that the same build will be pushed to other regions within the coming week. Expected markets include:

1. North America (United States, Canada)
2. Europe (EU member states and the UK)
3. India

Galaxy S25 owners in these territories should navigate to Settings → Software update → Download and install once the regional rollout is live. Samsung typically staggers the distribution to manage server load, so the update may appear at slightly different times across carriers.

Impact for Galaxy S25 users

The addition of Prioritise and Summarise Notifications directly addresses long‑standing complaints that the S25’s notification handling lagged behind newer models. By surfacing critical alerts first and collapsing verbose threads, the user experience becomes more efficient, especially for power users who rely on timely information.

File Summaries introduces on‑device AI document processing, a feature previously limited to the S26’s larger RAM pool. This means S25 owners can now skim contracts, reports, or e‑books without opening each file, preserving battery life and privacy by keeping data local.

Overall, the update narrows the functional gap between the S25 and its successor, reinforcing Samsung’s strategy of extending AI capabilities across its flagship lineup rather than reserving them for the newest hardware alone.

What to watch next

Analysts will be monitoring how quickly the international rollout proceeds and whether any region‑specific bugs emerge, particularly on carrier‑customized firmware. Additionally, the size of the update may prompt discussions about Samsung’s future approach to bundling AI models with security patches.

If the rollout proceeds smoothly, we can expect Samsung to continue back‑porting AI features to the Galaxy S24 and possibly the mid‑range A‑series, further democratizing on‑device intelligence across its ecosystem.
