Quick Answer
One UI 8.5 is rolling out as a stable update from Samsung, starting in South Korea and expanding globally. Headline upgrades include modular quick settings, a native lockscreen Depth Effect, an overhauled Galaxy AI Creative Studio inside Samsung Gallery, and a heavily upgraded Bixby that now runs on a local large language model.
Eligible devices include the Galaxy S25 series, the entire Galaxy S24 and S23 lineups, Z Fold7, Z Flip7, Z Fold6, Z Flip6, Z Fold5, Z Flip5, the Galaxy A56 and A36 mid range, and the Tab S11 and Tab S10 tablet lines.
Top New Features
1. Advanced Quick Settings and Lockscreen Depth Effect
The quick settings panel can be redesigned with modular fluid layout options, so users can prioritize specific toggles dynamically. On the lockscreen, a native Depth Effect engine automatically separates the wallpaper subject from the background, letting the system clock sit elegantly behind elements of the photo for a premium magazine style look.
2. Next Gen Bixby and Galaxy AI Expansion
Bixby has been rebuilt around a local large language model. It now handles complex multi turn contextual prompts, manages cross app workflows, and operates seamlessly without an active internet connection. The Galaxy AI Creative Studio is integrated directly into Samsung Gallery and can remove reflections, expand image borders intelligently, and generate cinematic slow motion clips from standard videos with zero stutter.
3. Granular App Folder and Widget Sculpting
App folders support unique shapes, gradients, and transparency levels that bypass traditional grid constraints. Smart Widgets use predictive on device AI to surface tools based on your historical usage, time of day, and geographic location.
Official Eligible Devices List
Flagship Vanguard
- Galaxy S Series. S25, S25+, S25 Ultra, S25 FE, plus the entire S24 and S23 lineups.
- Galaxy Foldables. Z Fold7, Z Flip7, Z Fold6, Z Flip6, and stable builds have officially landed on the legacy Z Fold5 and Z Flip5.

Performance and Battery Optimizations
"One UI 8.5 is not just visual flair. The RAM management algorithms have been rewritten to support background AI processing without killing battery longevity."
- Vivid display profile fix. Samsung refined the display rendering pipeline so the Vivid profile delivers rich saturation without crushing dark gradients.
- Thermal efficiency. Improved background task scheduling keeps the processor from spiking during intensive multitasking, leading to a cooler device and an average 5 to 8 percent gain in battery endurance.
How to Update Your Galaxy Device
- Open the Settings app on your Samsung Galaxy device.
- Scroll to the bottom and tap Software update.
- Tap Download and install.
- Make sure the device is on a stable Wi Fi connection and has at least 50 percent battery before starting the install.
The Bottom Line
One UI 8.5 is the cleanest pairing of Samsung hardware and on device AI to date. The headline grabbers are the LLM powered Bixby and the depth aware lockscreen, but the under the hood RAM and thermal upgrades are what users will actually feel day to day. Flagship, foldable, mid range, and tablet owners are all in the rollout window.
