Samsung has begun rolling out the June 2026 security patch for the Galaxy S23 lineup in South Korea. The 444.60MB update (firmware S918NKSS8FZF1) fixes 45 security issues and underscores Samsung's OS-upgrade trajectory toward One UI 8.5/Android 16.
Samsung has expanded its Galaxy S25 update (firmware S93xBXXUACZF1) beyond South Korea to Europe and India, adding the June 2026 security patch and the AI-powered Notification Highlights feature (Prioritize Notifications and Summarize Notifications). The feature analyzes message importance to surface key alerts and can summarize long conversations, currently only for notifications in the primary system language. The rollout should reach additional regions in coming days, and the capability first appeared with the Galaxy S26 series earlier this year.
One UI 8.5 introduces a major icon overhaul with subtle 3D depth, shadows, and gradients for both stock and third‑party icons, moving away from the flat 8.0 style and embracing a Frosted Glass aesthetic to create a premium, cohesive feel across Samsung’s software.
Samsung’s Galaxy S25 receives a larger-than-usual June 2026 security patch that also brings two Galaxy AI features from the Galaxy S26—Prioritise Notifications (highlights the most important alerts) and File Summaries (summarizes PDFs and TXT files)—via a separate update after the initial One UI 8.5 rollout.
SamMobile notes that while One UI 8.5 runs well on the latest Galaxy Ultras, several new features (including a 24‑megapixel mode and Horizontal Lock) aren’t available on older models like the Galaxy S23/S24/S25 Ultra, revealing a clear feature parity gap across generations.
Samsung’s One UI 8.5, built on Android 16 QPR2, may not reach several 2022 Galaxy models (including the S22 line, S21 FE, A73/A53/A33, Z Fold 4, Z Flip 4, Tab S8 series) because Samsung requires compatibility with Android 17, which these devices may not achieve. While newer phones will get 8.5, mid‑cycle updates are unlikely to continue; the S23 could potentially receive One UI 9 based on Android 17 in the future, but that remains uncertain. The update brings features like a redesigned quick panel, improved Bixby, enhanced lock screen options, a time-zone converter, and wireless sharing with Apple devices, plus an audio eraser.)
Samsung is expanding One UI 8.5 to more Galaxy devices (M56, M55, M54 and A25, A34, A54, A55) with May 2026 security patches, a refreshed Ambient Design, and camera/app enhancements including Direct Voicemail, Storage Share, and new film-like filters. Notably, the previously named 'Intense' camera filter has been renamed to 'Vivid Film' starting with the S26 series, keeping the same vivid effect under a clearer name.
Samsung has started rolling out One UI 8.5 for the Galaxy A16 5G in India and Indonesia (firmware A166PXXU7DZE2, ~2.3GB), adding UI refinements, a more customizable Quick Panel, new wallpapers, Weather and Clock enhancements, Direct Voicemail, improved Device Care, and other features, plus the May 2026 security patch; update via Settings > Software update and ensure at least 30% battery before installing.
Samsung has effectively ruled out bringing One UI 8.5 to 2022 devices (Galaxy S22, A53, A33) because 8.5 is built on Android 16 QPR2, a heavier update akin to a new Android version. The four-major-OS-upgrades promise was fulfilled with Android 16, development on 8.5 stalled, and only security patches will continue. Going forward, use Android 17 eligibility as a guide: if Android 16 was the last major OS, your One UI journey ends at 8.0. For new One UI features, upgrading to newer devices is likely you’ll need. Samsung still commits seven years of updates for current flagships, but mid-cycle upgrades aren’t guaranteed for older models.
Samsung’s One UI 8.5 update expands the Camera Assistant feature to around 20 devices, including Galaxy A34/A35/A36/A37 and M34/M35/M36 phones as well as multiple Galaxy Tab models, giving users more advanced camera controls like extra lens/zoom options and autofocus tweaks. Some features may be limited by hardware on older devices. The rollout began in Korea on May 6, 2026, with broader availability starting May 11.
A rumor suggests the Galaxy S25 series may receive two Galaxy S26 AI features—Priority Notifications and Summarize Notifications—in a future software update (potentially June 2026); there’s no official confirmation yet, and other missing S25 features (e.g., 24MP camera option, Finder, Now Nudges) remain unaddressed as One UI 8.5 rolls out.
Samsung’s Galaxy S23 series received One UI 8.5, but notably lacked AirDrop-style file sharing, prompting backlash from owners who expected the feature. Some discussions suggest the hardware could technically support AirDrop, but backporting would require effort from Samsung and Google, which seems unlikely given device-support policies. With the S23 line still slated for major updates, fans are frustrated at missing a key feature that newer Galaxy models reportedly include.
Samsung has begun rolling out One UI 8.5 to the Galaxy A17 4G in South Korea (firmware A175NKSU5CZE9), bringing a refreshed UI, improved stock apps, smarter Bixby with natural language and Perplexity integration, Storage Share, faster Wireless DeX access, Auracast enhancements, and updated lock screen/Weather/Clock features; expansion to other regions is expected soon, with installation requiring at least 30% battery.
Samsung’s One UI 8.5 removes the in-camera video filters that were available in One UI 8.0 for Galaxy phones; users must record first and apply looks via Samsung Studio or Galaxy Store packs, which can compress footage. The Pro Video mode’s Log with Cinematic LUTs remains, but recording Log is limited to the Galaxy S24 series and newer. Samsung hasn’t explained the change, and the feature isn’t restored in One UI 9.0 beta.
Galaxy S23 owners are upset that the One UI 8.5 update removes AirDrop-style file sharing despite hardware support; Samsung hasn’t explained the decision, though workarounds like Quick Share QR codes and NearDrop exist, while the update adds other UI improvements and Galaxy AI features; the controversy has sparked discussions of planned obsolescence as the S23 still has about a year of software updates left.
