Samsung Backports Galaxy S26’s Best AI Tools to Galaxy S25

What the June Galaxy S25 Update Changes

Samsung’s June Galaxy S25 update is a firmware release that backports selected Galaxy S26 AI features—especially smarter notifications and document summaries—to last year’s flagship phones, while still withholding some headline tools for newer hardware, making the rollout a clear snapshot of Samsung’s tiered Galaxy AI strategy. The update, a roughly 900MB package that arrived after the initial One UI 8.5 build, adds AI-powered Prioritize Notifications, Summarize Notifications, and File Summaries to the Galaxy S25 line and comparable foldables. According to TechCabal, the June build landed on June 11 with a size “noticeably larger than a typical security patch, and for good reason.” Samsung had launched these tools on the Galaxy S26 alongside One UI 8.5, but S25 owners were surprised to find them missing at first, signaling that the company planned a staggered AI rollout instead of a single feature-complete upgrade.

Galaxy S26 AI Features Now On Galaxy S25

The June Galaxy S25 update finally delivers the most practical Galaxy S26 AI features users had been waiting for. Prioritize Notifications uses on-device Galaxy AI to reorder alerts so important messages rise to the top, while less relevant pings are pushed down, helping reduce notification fatigue without sending data to the cloud. Summarize Notifications collapses dense email threads and group chats into concise, plain-language overviews, so you understand what changed without opening each app. File Summaries lives inside Samsung’s My Files and Voice Recorder apps, generating short summaries for PDF and TXT files, plus stored voice recordings. These tools rely on the same on-device language support list that launched on the Galaxy S26, so they only work when notification or file content matches the system language. Together, they bring a large part of the Galaxy S26 AI experience to S25 owners via One UI 8.5.

The Features Samsung Still Keeps S26-Only

Even with the June Galaxy S25 update, several Galaxy S26 exclusives remain out of reach. The biggest omission is Now Nudge, Samsung’s context-aware assistant that reads what is on screen and surfaces suggestions through the Samsung Keyboard toolbar, such as creating calendar events or saving contacts. TechCabal notes that Now Nudge currently appears only on the Galaxy S26 series, despite firmware evidence that it does not depend on unique S26 hardware. Camera upgrades are also uneven. The S26 Ultra’s 24MP AI Fusion shooting mode, video softening controls, and Horizon Lock stabilization have not arrived on the S25 Ultra, even though both run the same Camera Assistant version. A fingerprint accuracy booster, which lets you rescan prints repeatedly, oddly reached the Galaxy S25 FE and Z Fold 7 before the standard S25 trio. These gaps show that parity between One UI 8.5 devices is still far from complete.

Why Older Galaxy Flagships Miss Out

Older Galaxy S phones like the S24 and S23 remain on a thinner AI diet, despite running versions of One UI 8.5. The S24 series has some modern perks such as Quick Share with Apple devices, but Android Central reports it is not yet confirmed to receive the June AI notification and file features on the same timeline as the S25. The S23 line fairs worse, with a reduced One UI 8.5 build missing both cross-platform Quick Share and Call Screen. Meanwhile, foldables like the Z Fold 7 and Z Flip 7 share the S25’s partial gains and gaps: they now include the new AI notification and file tools, and in the Fold 7’s case the fingerprint booster, but still lack Now Nudge and camera extras. This patchwork hints that Samsung is drawing a firm capability line around its latest two hardware generations.

What Samsung’s AI Rollout Strategy Reveals

The June Galaxy S25 update suggests a deliberate, hardware-tiered AI roadmap rather than a uniform software upgrade policy. By backporting Galaxy S26 AI features like Prioritize Notifications and File Summaries, Samsung shows willingness to extend its Galaxy AI value proposition beyond the newest model, giving S25 buyers some future-proofing. At the same time, reserving Now Nudge, advanced camera controls, and Horizon Lock for the S26 underscores that the company still wants clear differentiation at the top of the lineup. Technobezz notes that the S25 series is “next in line for the One UI 9 beta,” which could bring Now Nudge or other withheld tools, but that is not guaranteed. For users, this means AI capabilities will likely roll out in waves, with core utilities eventually trickling down while the most eye-catching features remain tied to the latest flagship generation.
