Galaxy S25 June 2026 Update Adds Missing One UI 8.5 AI Features
Samsung's June security update for the Galaxy S25 delivers more than a patch. Three Galaxy AI features that were absent from last month's stable One UI 8.5 release are now rolling out to the S25 series, giving owners tools that have been exclusive to the Galaxy S26 since that phone launched. The update is live in South Korea today and expected to reach North America, Europe, and India within the coming week, Android Authority and GSMArena reported Thursday.
The three features are Prioritize Notifications, Summarize Notifications, and File Summaries. None made it into stable One UI 8.5 when Samsung shipped it last month.
That omission was unexpected. One UI 8.5 arrived after ten beta builds and was understood to be Samsung's vehicle for bringing most S26-exclusive AI capabilities to the S25. It did deliver several: Agentic AI, Creative Studio, a Bixby-powered call screening feature, and pro-grade camera tools all came with the May release, per Android Authority and Samsung Newsroom. But Prioritize Notifications, Summarize Notifications, and File Summaries were held back without explanation.
Samsung is now closing that gap through its regular monthly update schedule rather than a separate named release. The June patch weighs around 900MB, noticeably larger than the 583MB stable One UI 8.5 package, and early adopters were quick to note the unusual size for what was billed as a security update, Android Authority reported Thursday.
Galaxy S25 Galaxy AI features update: what Prioritize Notifications, Summarize Notifications, and File Summaries do
The three additions share a common design philosophy: on-device processing, no data sent to Samsung's servers, and a focus on reducing friction with information the phone already has.
Prioritize Notifications reorders incoming alerts by importance, pulling the ones Galaxy AI judges most critical to the top of the notification stack. The ranking is based on notification content and what the phone knows about the user, all processed locally, Android Police reported Thursday. One constraint worth flagging: the feature only works when incoming notifications are in the same language as the phone's system language. For users who receive messages in multiple languages, that limitation could matter.
Summarize Notifications tackles a different problem. Group chats and stacked email threads can generate dozens of individual alerts from a single ongoing conversation, and reading through them one at a time is slower than it needs to be. The feature collapses those threads into a plain-language overview, letting users get the gist of an exchange without opening each notification, per Android Authority Thursday. Like Prioritize Notifications, processing stays on the device, Android Police noted.
File Summaries works differently from the other two. Rather than acting on notifications, it generates brief AI-powered overviews of PDF and TXT files stored locally on the device, useful for getting the shape of a document without opening it in a separate app, per Android Police and Android Authority Thursday. GSMArena also says the feature can summarize Voice Recorder recordings, though that detail doesn't appear in the other reports covering Thursday's rollout.
What the available coverage does not address is how well any of these features perform in practice. No outlet has published independent assessments of accuracy, edge cases, or how the prioritization logic handles ambiguous notifications. The descriptions above reflect intended functionality, not tested results.
One more detail from Android Police: these features are expected to extend beyond the S25 series to the Galaxy Z Fold 7 and Flip 7, which share the same underlying hardware. That expansion isn't confirmed by Samsung directly, but the shared silicon makes it a reasonable expectation.
What's still missing from the Galaxy S25
With Thursday's additions, the S25 now has access to almost all the same Galaxy AI features as the S26, Android Police reported. The gap that remains is real, though.
Several S26 capabilities are still absent from the S25 as of this update: Now Nudge, 24MP camera support, video softening, and the fingerprint accuracy booster, Android Authority noted in late May. The fingerprint accuracy booster has its own odd footnote in this story: it arrived on the Galaxy S25 FE before any other S25 variant, which no one has publicly explained. The camera and fingerprint features are listed without a timeline for backporting to the standard S25 lineup, and neither Android Authority nor other outlets confirmed whether those absences are scheduling decisions or tied to hardware differences between generations.
The feature gap could widen again before Samsung addresses what's left. Android 17-based One UI 9 is currently in limited public beta on the Galaxy S26 series, and whatever that update introduces will restart the cycle, Android Police noted Thursday.
Rollout status and how to check
The June update is live in South Korea under firmware version S93xNKSUACZF1, carrying the June 2026 Android security patch level, per GSMArena and Android Authority. Samsung also started the May One UI 8.5 rollout in South Korea before expanding to other regions, per Samsung Newsroom, so the sequencing is consistent with how the company handles major updates.
A broader rollout covering North America, Europe, and India is expected within the coming week, Android Authority reported Thursday. Carrier-specific timelines and regional variants may mean some users in those markets receive it later than others.
South Korean owners who haven't received a notification can check manually through Settings > Software Update > Download and Install, per GSMArena and Android Authority. Owners in other regions can set up the same check now and run it again once the rollout expands.
The June update doesn't close every gap between the S25 and S26, but it's a meaningful step. Three features that S25 owners were waiting on since May are now arriving through the least dramatic possible delivery mechanism: a security patch that happened to be carrying more than its label suggested.
