One UI 8.5
Samsung just dropped the One UI 8.5 beta program for Galaxy S25 owners, and honestly? It’s one of their most ambitious software updates yet. I’ve been tracking Samsung’s beta programs for years, and this one’s packed with features that actually matter—not just visual tweaks that look pretty in press releases.
If you’re holding a shiny new Galaxy S25, S25+, or S25 Ultra, you’re probably wondering what all the fuss is about. Let me walk you through everything: how to get it, what’s new, what might break, and whether you should install it right now or wait for the stable release.
What Is the One UI 8.5 Beta Program?
The One UI 8.5 beta is Samsung’s testing ground for their next major software update, built on Android 16 QPR2. Think of it as an early access pass to features that’ll eventually roll out to millions of Galaxy devices worldwide.
Right now, the beta program is exclusive to the Galaxy S25 series—that’s the S25, S25+, and S25 Ultra. Samsung’s playing it safe by limiting initial access to their newest flagship lineup, which makes sense given these phones have the hardware to properly showcase the new features.
Currently eligible countries include:
- United States
- United Kingdom
- South Korea
- Germany
- India
- Poland
More markets are expected in Phase 2, likely expanding to other European and Asian regions. If you’re not in these countries yet, you’re probably looking at a few weeks’ wait.
How to Enroll in the One UI 8.5 Beta Program
Getting into the beta is straightforward, but there’s a catch—slots fill up fast. Here’s exactly what you need to do:
- Open the Samsung Members App (not the Galaxy Store—common mistake)
- Look for the One UI 8.5 Beta banner on the home screen
- Tap “Register” and agree to the terms
- Head to Settings > Software Update > Download and Install
- Wait for the beta firmware to download (it’s usually 2-3GB)
The whole process takes about 20-30 minutes depending on your internet speed. You’ll need to restart your phone after installation.
Important heads-up: Beta slots are limited per country. Samsung typically opens registration windows, and once capacity is reached, you’ll need to wait for the next wave. I’ve seen registration fill up within hours during previous beta programs.
The Biggest New Features in One UI 8.5
Let’s talk about what actually matters. Samsung packed this update with features across three main categories: AI-powered creativity, cross-device connectivity, and security fortifications.
Photo Assist Continuous Edit: AI That Actually Works
This is the headliner feature, and it’s legitimately impressive. Unlike the old Photo Assist where you’d make an edit, wait, then make another edit, the new Continuous Edit mode lets you stack multiple AI-powered changes without interruption.
Here’s how it works in practice: You can remove a person from the background, adjust the lighting, change the sky, and add creative effects—all in one fluid workflow. The AI processes everything continuously rather than making you wait between each edit.
The catch? Every image you create or heavily modify gets a Generative Edit Watermark—a small digital tag that identifies AI-modified content. This is Samsung’s response to growing concerns about content authenticity. You can’t remove it, and honestly, you shouldn’t want to. It’s about transparency.
The watermark appears in the image metadata and sometimes as a visible indicator, depending on the extent of AI manipulation. It’s Samsung’s way of saying “this is AI-enhanced content,” which matters in an era where deepfakes and misinformation are real concerns.
Storage Share: Your Files, Everywhere
If you’ve ever tried to access a file from your phone while working on your laptop, you know the pain. Storage Share solves this by creating seamless file access across your Samsung ecosystem.
Here’s what makes it special: Files stored on your Galaxy S25 become instantly accessible on your Galaxy Book, Galaxy Tab, or even your Samsung Smart TV—no manual syncing, no cloud uploads eating your data plan, no friction.
The feature integrates directly into the My Files App, so there’s no new interface to learn. You just browse your phone’s storage from your laptop as if it were a local folder.
Requirements for Storage Share:
- All devices must be signed into the same Samsung account
- Devices need compatible firmware (Galaxy Book 4 series and newer, Galaxy Tab S10+, etc.)
- Both devices must be on the same network or connected via Samsung’s secure cloud bridge
- You’ll need to enable the feature in Settings > Connected Devices
One thing I love: it works bidirectionally. Edit a document on your tablet, and the changes appear on your phone instantly. It’s what Apple’s ecosystem has been doing for years, and Samsung’s finally caught up.
Audio Broadcast with Auracast: Share Your Sound
Auracast is Samsung’s implementation of LE Audio broadcasting, and it opens up genuinely useful scenarios. The basic idea: your phone can broadcast audio to multiple compatible LE Audio-supported devices simultaneously.
Practical use cases:
- Guided tours: Use your phone as a microphone, broadcasting your voice to multiple Galaxy Buds-wearing listeners
- Silent disco mode: Multiple people listening to the same music from one phone, each controlling their own volume
- Accessibility: Broadcasting TV audio directly to hearing aids or earbuds
To use Auracast, you’ll need LE Audio-compatible devices—currently that’s the Galaxy Buds 5 Pro (expected) and select newer wireless earbuds. Older Bluetooth devices won’t work because they lack the required hardware.
Setting up Auracast:
- Open Quick Panel > Tap Media output
- Select “Audio Broadcast”
- Enable broadcasting and set a connection code (optional)
- Other LE Audio devices can now discover and join your broadcast
The voice broadcasting feature specifically turns your phone into a wireless microphone system, which is incredibly useful for tour guides, fitness instructors, or anyone needing to address a group without shouting.
One UI 8.5 Security Upgrades: Theft Protection and More
Samsung’s getting serious about device security with two major additions: Theft Protection and Failed Authentication Lock.
Theft Protection (New)
This feature adds multiple layers of defense if someone steals your phone:
- Automatic lockdown when the phone detects suspicious movement patterns (like a grab-and-run)
- Remote lock strengthening that prevents factory resets without your Samsung account
- Offline protection that works even when the thief turns off connectivity
The system uses on-device AI to detect theft patterns—sudden acceleration, unusual geographic movement, or attempts to disable security features. When triggered, your phone becomes a very expensive paperweight.
Failed Authentication Lock
Here’s how this works: After multiple failed biometric attempts (fingerprint, face, or PIN), your phone requires your Samsung account password before allowing any more attempts. This blocks brute-force attacks where someone tries to guess your PIN thousands of times.
Additional security features include:
- Enhanced Identity Check Protection for sensitive settings changes
- Smarter Software Update Controls that let you postpone updates during critical work periods
- Integration with Samsung Knox at the hardware level
To enable Theft Protection:
- Go to Settings > Security and Privacy
- Scroll to “Theft Protection”
- Toggle on “Detect suspicious activity”
- Configure your trusted locations (optional—your phone won’t trigger theft mode at home)
Visual Redesign: One UI 8.5’s New Look
Samsung’s design team has been busy. The Visual Redesign in One UI 8.5 focuses on depth, customization, and subtle refinements rather than a dramatic overhaul.
3D-Style App Icons
The new app icons add dimension through layered shadows and highlights. They’re not fully 3D—more like 2.5D—but the effect adds polish. You’ll notice the difference most on the home screen and in the app drawer.
The redesign affects system apps first (Phone, Messages, Camera, Gallery) with third-party app icons remaining unchanged until developers update their apps.
Customizable Quick Panel
This is huge for power users. The Quick Panel (Samsung’s version of Android’s quick settings) now lets you:
- Resize individual toggles (make Wi-Fi bigger, make Airplane Mode smaller)
- Rearrange in a custom grid (not just the standard 4×2 layout)
- Add transparency effects to see your wallpaper through the panel
- Create custom toggle groups for different scenarios (Work mode, Gaming mode, etc.)
To customize: Pull down Quick Panel > Tap the three-dot menu > “Edit buttons” > Long-press any toggle to resize or rearrange.
Performance and Animation Improvements
Under the hood, Samsung’s optimized animations to feel smoother. The Performance Upgrades focus on:
- Faster app launch times (particularly noticeable on demanding apps)
- Smoother scrolling through long lists
- Reduced frame drops during multitasking
- Better thermal management during sustained loads
The Redesigned Power Management system learns your usage patterns and optimizes background processes accordingly. If you always game at 8 PM, your phone will pre-optimize for performance. If you’re usually sleeping at 3 AM, it’ll aggressively manage background activity.
One UI 8.5 vs One UI 8.0: What Actually Changed?
Let me break down the major differences in a way that actually makes sense:
| Feature | One UI 8.0 | One UI 8.5 | Impact |
|---|---|---|---|
| Photo Editing AI | Single-step edits | Continuous multi-edit flow | High – Workflow is genuinely faster |
| Cross-Device Files | Manual sharing via Quick Share | Automatic Storage Share integration | High – Game-changer for multi-device users |
| Audio Sharing | Basic Bluetooth pairing | LE Audio Auracast broadcasting | Medium – Requires new hardware |
| Theft Protection | Standard Find My Device | AI-powered theft detection | High – Meaningful security improvement |
| Quick Panel | Fixed layout | Fully customizable grid | Medium – Nice for customization enthusiasts |
| App Icons | Flat design | 3D-style with depth | Low – Aesthetic preference |
| Battery Management | Adaptive Battery | Context-aware power profiles | Medium – Noticeable in daily use |
The most impactful upgrades are the AI editing workflow, Storage Share, and Theft Protection. Everything else is iterative polish—welcome, but not revolutionary.
Known Issues: One UI 8.5 Beta Bugs & Problems
Beta software breaks things. That’s the whole point of beta testing. Here are the most commonly reported issues:
Battery Drain Issues
The big one. Many beta testers report faster battery drain, particularly in the first few days. This usually happens because:
- Background services are reindexing and optimizing
- New AI features are learning your usage patterns
- The system hasn’t yet optimized for your specific app combination
Temporary fixes:
- Restart your phone twice after installation
- Clear cache for high-drain apps (Settings > Apps > [App Name] > Storage > Clear Cache)
- Disable “Enhanced processing” in Battery settings for 24 hours while the system optimizes
- Turn off Storage Share if you’re not actively using it
Battery life typically stabilizes after 3-4 days as the system completes its optimization.
Auracast Connection Instability
LE Audio broadcasting sometimes drops connections, especially when moving between rooms or when multiple devices are connected. This appears to be a firmware issue that Samsung’s addressing in subsequent beta builds.
Storage Share Sync Delays
Some users report files taking 10-15 seconds to appear on connected devices rather than being instant. This seems related to network configuration—works better on 5GHz Wi-Fi than 2.4GHz.
App Compatibility Problems
A handful of banking apps, security apps, and some games detect the beta software and refuse to run (they flag it as “rooted” even though it isn’t). This is standard beta behavior—these apps should work fine once the stable version launches.
Quick Panel Customization Crashes
The customization interface occasionally freezes when rearranging more than 12 toggles. Workaround: Customize in smaller batches, save, then continue.
How to Report Bugs:
- Open Samsung Members App
- Tap “Error Reports” in the beta section
- Describe the issue with steps to reproduce
- Attach screenshots or screen recordings if possible
Samsung actually reads these reports and often fixes critical issues within weekly beta updates.
Should You Install One UI 8.5 Beta Right Now?
Here’s my honest take based on testing beta software for over a decade:
Install the beta if:
- You have a backup phone you can switch to if something breaks
- You’re comfortable troubleshooting occasional bugs
- You want to experience new features before everyone else
- Battery drain for a few days doesn’t bother you
- You’re excited to provide feedback to Samsung
Wait for stable if:
- Your S25 is your only phone
- You rely on banking apps or work apps that might break
- Battery life is critical for your daily routine
- You get frustrated by minor glitches and crashes
- You prefer polished, tested software
The One UI 8.5 Stable Rollout is expected in the first half of 2026, likely coinciding with the Galaxy S26 series launch. That’s roughly 4-6 months from now.
How to Safely Downgrade from One UI 8.5 Beta
Changed your mind? Hate the bugs? Here’s the nuclear option—downgrading back to stable One UI 8.0.
Warning: This process wipes your phone completely. Back up everything first.
Step-by-step downgrade process:
- Back up your data via Samsung Cloud or Smart Switch to your PC
- Download Samsung Smart Switch on your Windows or Mac computer
- Connect your phone via USB cable
- Open Smart Switch and select “More” > “Emergency Software Recovery and Initialization”
- Enter your device model number when prompted
- Click “OK” to begin the firmware download and installation
- Wait 20-30 minutes for the process to complete (don’t disconnect!)
- Set up your phone and restore your backup
Alternative method using Samsung’s official firmware:
- Download your device’s official firmware from Samsung’s update servers
- Use Odin (Windows only) to flash the stable firmware
- This method is more technical but gives you more control
After downgrading, you cannot re-join the beta program for the current cycle. You’ll need to wait for the next beta phase or the stable release.
Will Galaxy S24 Get One UI 8.5?
This is the question I get asked most. Short answer: Yes, but not yet.
The One UI 8.5 features for Galaxy S24 (and S24+, S24 Ultra) will arrive later in 2026, likely in Q2 or Q3. Samsung always tests on their newest flagship first, then rolls features to previous-generation devices.
What S24 owners can expect:
- Most major features (Photo Assist updates, Storage Share, Auracast)
- Security enhancements (Theft Protection, Failed Authentication Lock)
- Visual redesign elements
- Performance optimizations tailored to Snapdragon 8 Gen 3 / Exynos 2400
What S24 might not get:
- Some AI features that require the newer NPU in S25’s Snapdragon 8 Elite chip
- Certain camera AI improvements tied to S25’s camera hardware
- Minor features Samsung reserves for flagship differentiation
The Galaxy S23 series will likely also receive One UI 8.5, though possibly with further feature reductions. S22 and older are less certain—Samsung typically supports devices for 4 years of major updates, so S22 (launched 2022) is approaching its support window end.
What’s Android 16 Bringing to One UI 8.5?
One UI 8.5 is based on Android 16 QPR2 (Quarterly Platform Release 2), which means it includes Google’s latest features plus Samsung’s customizations.
Core Android 16 features in One UI 8.5:
- Notification improvements: Better grouping and smarter priority sorting
- Privacy Dashboard enhancements: More granular permission controls
- Predictive back gestures: Smoother navigation animations
- Performance optimizations: Better memory management and background app handling
Samsung’s additions over stock Android 16:
- The entire Galaxy AI suite (Photo Assist, Quick Share enhancements, etc.)
- Samsung-exclusive security features (Knox-powered theft protection)
- Ecosystem integrations (Storage Share, Auracast implementation)
- Custom UI elements (3D icons, customizable Quick Panel)
Google’s stock Android 16 on Pixel devices looks and feels quite different from One UI 8.5. Samsung adds significant functionality but also visual complexity that stock Android users might find overwhelming.
The relationship works like this: Android 16 is the foundation (the engine), One UI 8.5 is Samsung’s custom bodywork, interior, and feature additions on top. You’re getting Google’s core improvements with Samsung’s ecosystem benefits layered on top.
One UI 8.5 Quick Panel Customization Masterclass
Since the customizable Quick Panel is one of the most practically useful features, here’s a deeper dive on making it work for you.
Advanced customization options:
1. Create Context-Based Layouts
- Set up a “Work Mode” panel with only work-relevant toggles
- Configure a “Gaming Mode” panel with performance toggles front and center
- Design a minimal “Focus Mode” panel with just Do Not Disturb and eye comfort
2. Resize Toggles by Priority
- Make your most-used toggles (Wi-Fi, Bluetooth) 2×2 size
- Shrink rarely-used toggles (NFC, Ultra Wideband) to 1×1
- Position critical toggles in top-left where your thumb naturally reaches
3. Use Transparency Strategically
- Enable transparency if you have a beautiful wallpaper you want to see
- Disable transparency if you prioritize readability in bright sunlight
- Adjust transparency percentage based on wallpaper darkness
4. Group Related Toggles
- Cluster connectivity toggles (Wi-Fi, Bluetooth, Mobile Data)
- Group performance toggles (Game Booster, Performance Mode, Power Saving)
- Place security toggles (Secure Folder, Private DNS) together
To access advanced customization: Quick Panel > Three dots > Edit buttons > Tap the gear icon > Advanced settings.
