The first wave of compatible devices includes the Samsung Galaxy S25 series (including the S25 FE), Galaxy S24 lineup (S24, S24 Plus, S24 Ultra, and S24 FE), Galaxy Z Fold 7 and Flip 7, Galaxy Z Fold 6 and Flip 6, along with the Galaxy Tab S11 and Tab S10 tablet families [4](https://www.tomsguide.com/phones/samsung-phones/one-ui-8-5-lMany of the One UI 8.5 features originally debuted on the Galaxy S26 series, and Samsung is now bringing them to older devices.aunches-for-millions-of-samsung-phones-this-week-heres-whats-new/). This broad compatibility means users of older Galaxy phones can access cutting-edge capabilities without purchasing new hardware.

Galaxy S26 features arrive on older devices through Galaxy AI enhancements

The most significant additions in One UI 8.5 are new AI features that debuted with the Galaxy S26 series in February 2026. Samsung effectively used these capabilities as time-limited exclusives for its latest flagship, but the wait appears worthwhile for owners of previous-generation devices 1

1

. Agentic AI represents the headline feature, bringing sophisticated multi-step task automation across apps. Bixby now operates with enhanced intelligence powered by Perplexity, enabling "anything, anytime" queries and the ability to handle complex requests like finding specific photos and emailing them to contacts without manual intervention 5

5

.

AI Call Screening stands out as a practical communication tool that answers unknown callers automatically, asks about the reason for the call, and displays live transcripts so users can decide whether to pick up 5

5

. Live Voicemail Transcripts complement this by letting users read messages in real time while they're being recorded. The software update also introduces Now Nudge, a keyboard productivity feature that suggests calendar entries, useful facts, or relevant actions based on active conversations 5

5

.

Creative Studio and AI photo editing tools transform image manipulation

Galaxy AI capabilities extend significantly into photography with Creative Studio and Text-to-Edit Photo Assist, which allow prompt-based editing where users simply type what they want changed rather than manually adjusting settings 1

1

. This includes requesting new backgrounds or adding objects through natural language commands. Object Transfer enables moving people or objects from one photo to another directly within the gallery app 5

.

AI photo editing receives further enhancements through improved Audio Eraser capabilities and better AI Select options 2

2

. Mobile photographers will appreciate dual recording from rear and selfie cameras for vlogging, while pro video creators gain real-time LOG video color previews. Document scans now handle multi-page text more effectively and better deal with stray fingers in the frame 3

3

. Auto motion photos intelligently limit "live" shots to scenes with actual movement, reducing unnecessary captures.

Enhanced connectivity features include Quick Share and live translation improvements

One UI 8.5 expands Quick Share functionality with broader AirDrop support across more Samsung devices, simplifying file and photo exchanges with iPhone, iPad, and Mac users 3

3

. This cross-platform compatibility addresses a long-standing friction point for users in mixed-device environments. Live translation becomes more seamless as Interpreter can automatically detect which language is being used after initial language setup at conversation start 3

3

.

The update includes storage sharing capabilities with other Samsung hardware, plus the ability to enable sharing for cameras and hotspots across family members 3

3

. Enhanced Auracast features and voice broadcasts expand audio connectivity options, while improved Bluetooth hearing aid controls make accessibility features more accessible [4](https://www.tomsguide.com/phones/samsung-phones/one-ui-8-5-lMany of the One UI 8.5 features originally debuted on the Galaxy S26 series, and Samsung is now bringing them to older devices.aunches-for-millions-of-samsung-phones-this-week-heres-whats-new/).

Interface refinements and personalization options expand user control

Beyond Galaxy AI additions, One UI 8.5 delivers interface improvements that enhance daily usability. The quick settings panel gains more customization options, while power saving now includes both Standard and Maximum modes for different battery conservation needs 3

3

. Lock screens and home screens become more dynamic with automatic lock screen layouts, interactive wallpapers, and more customizable clock fonts [4](https://www.tomsguide.com/phones/samsung-phones/one-ui-8-5-lMany of the One UI 8.5 features originally debuted on the Galaxy S26 series, and Samsung is now bringing them to older devices.aunches-for-millions-of-samsung-phones-this-week-heres-whats-new/).

AI Weather Effects add animated lock screen wallpaper that responds to local weather conditions like rain or snow, bringing visual interest to everyday interactions 5

5

. Weather alarm backgrounds and an enhanced weather widget with pollen index data cater to users who want environmental awareness at a glance [4](https://www.tomsguide.com/phones/samsung-phones/one-ui-8-5-lMany of the One UI 8.5 features originally debuted on the Galaxy S26 series, and Samsung is now bringing them to older devices.aunches-for-millions-of-samsung-phones-this-week-heres-whats-new/). The update also includes transparent blurs and floating elements reminiscent of iOS design language 3

Security and health features receive meaningful upgrades

Security enhancements in One UI 8.5 include privacy alerts, optional failed authentication locks, and multi-device security status checks that provide comprehensive protection across Samsung ecosystems 3

3

. Theft protection features help safeguard devices, while users can temporarily disable Auto blocker when needed and avoid unwanted sharing requests [4](https://www.tomsguide.com/phones/samsung-phones/one-ui-8-5-lMany of the One UI 8.5 features originally debuted on the Galaxy S26 series, and Samsung is now bringing them to older devices.aunches-for-millions-of-samsung-phones-this-week-heres-whats-new/).

Health-conscious users gain antioxidant measurements from their watches, meditation controls accessible from wearables, and more detailed weekly reports that provide deeper insights into wellness metrics 3

3

. These additions position Samsung's ecosystem as increasingly integrated across devices for users invested in multiple products.

What this means for Samsung users and future device strategies

The One UI 8.5 release represents more than a typical mid-cycle update, functioning as the upgrade One UI 8 should have been according to industry observers 2

2

. By bringing Galaxy S26 series capabilities to older Galaxy phones, Samsung demonstrates commitment to extending premium features across its lineup rather than restricting them permanently to new hardware. This approach could influence purchasing decisions, as users may feel more confident that their devices will receive meaningful updates beyond basic security patches.

While Samsung hasn't announced timing for Galaxy A series devices, historical patterns suggest these mid-range phones and tablets will eventually receive One UI 8.5, though with some feature limitations based on hardware capabilities 3

3

. High-end camera features like LOG video and computationally-intensive Galaxy AI tools may not reach budget devices, but most core additions should arrive. As the rollout continues globally, users should monitor their device settings for update notifications over the coming days, with availability varying by region and carrier.
