- Beta Expansion: The One UI 8.5 beta program, previously exclusive to the Galaxy S25 series, is now open for the Galaxy Z Fold7 and Galaxy Z Flip7 in India and South Korea.
- Major Update: The beta is a significant 4.2GB download based on Android 16, featuring an updated UI, new features, and improved Galaxy AI capabilities.
- Security Patch: The update includes the February 2026 Android security patch for enrolled beta testers.
Samsung's latest software experiment just got a lot more interesting. The company is opening up its One UI 8.5 beta program, which kicked off on the Galaxy S25 series, to its newest foldables. Starting now, if you're in India or South Korea with a Galaxy Z Fold7 or Z Flip7, you can sign up to test the next big Android skin. This isn't just a minor tweak, it's a massive 4.2GB package based on Android 16. The goal here is clear: Samsung needs real-world data on how its new AI and interface changes work on devices that bend in half before this software ships to everyone.
Update Overview: One UI 8.5 Beta
- Update Name: One UI 8.5 Beta
- Android Version: Android 16
- Update Type: Beta Software / Feature Update
- Size: Approximately 4.2GB
- Rollout Status: Beta program now open for registration
- Current Regions: India and South Korea (initially)
- Security Patch Level: February 2026
Let's be blunt. This is beta software. It's for tinkerers, developers, or anyone with a spare phone they don't mind breaking. It is not a critical security patch. It is not a stable release. Bugs, crashes, and weird battery drain are not just possible, they're expected. Think twice before you install this on the one phone you need to work perfectly every day.
Which Phones Get It and When
You can't just wake up and download this. You need a specific, very new Samsung phone and you have to enroll through the Samsung Members app.
Phones That Can Sign Up Today
- Samsung Galaxy Z Fold7: Beta available now in India and South Korea.
- Samsung Galaxy Z Flip7: Beta available now in India and South Korea.
- Samsung Galaxy S25 Series (S25, S25+, S25 Ultra): Beta program was previously opened and is ongoing.
Rollout Schedule
| Device | Region | Status | Expected Date / Notes |
|---|---|---|---|
| Galaxy Z Fold7 / Z Flip7 | India, South Korea | Beta program open now | Initial launch regions as of late February 2026. |
| Galaxy Z Fold7 / Z Flip7 | United Kingdom, USA, Germany, Poland | Expansion expected | Beta expected to expand to these regions soon, per sources. |

India Rollout Note: For the beta program, India is part of the first wave of regions alongside South Korea. For stable public releases, Samsung typically follows a staged rollout in India starting 1-3 weeks after the global launch. This process can be further delayed by carrier validation (Jio, Airtel, Vi). To manually check for the beta update after enrolling, go to Settings > Software update > Download and install.
Software Details and Firmware Versions
If you're the type who checks build numbers, here's what the first beta looks like on the foldables. All of these are about 4.2GB and bundle in Google's latest security fixes.
Confirmed Firmware Versions
- Galaxy Z Fold7 (South Korea): F966NKSU8ZZC5
- Galaxy Z Fold7 (India): F966BXXU8ZZC5
- Galaxy Z Flip7 (South Korea): F766NKSU8ZZC5
All the above builds are approximately 4.2GB in size and include the February 2026 Android security patch.
What's Actually New in One UI 8.5
Samsung isn't handing out a detailed changelog, but we know the broad strokes. This is an Android 16 build, so think of it as the foundation. On top of that, Samsung is layering its own changes.
Updated User Interface & Galaxy AI Integration
The focus is on a visual refresh and smarter AI. For the Fold7, that probably means better multitasking layouts and apps that understand they're on a big, unfoldable screen. The Flip7 might get better cover screen widgets or AI features that activate when you partially close the phone. The real test is making the jump from the small screen to the big one feel natural, not jarring.
Performance and Optimization
A 4.2GB download doesn't happen for a few new icons. That size hints at real work under the hood, likely targeting the unique battery and performance demands of running two displays. Samsung's newest chips are getting pushed to do more with less power.
India Context: Here's the catch for users in India. When this software goes stable, don't assume you'll get every single AI feature shown off in global ads. Samsung has a history of geo-fencing certain AI tools. What you get might be a subset of the full package.
How to Get the Beta on Your Phone
If you've read this far and still want in, here's your path. Remember, you're signing up for potential headaches.
- Make sure your Fold7, Flip7, or S25 is fully updated on its current, official software.
- Grab the Samsung Members app from the Galaxy Store or Play Store.
- Open it and log in with your Samsung account.
- Look in the Benefits or Notices tab for a banner about the "One UI 8.5 Beta Program".
- Tap it, agree to the terms, and register.
- After that, head to Settings > Software update > Download and install.
- The beta should appear. Hit Download and grab a coffee. It's a big file.
Don't Even Think About Skipping This
- Battery: Plug in your phone or make sure it's above 50%.
- Wi-Fi: Use it. You do not want to download 4.2GB on cellular.
- Backup: Do a full backup. To Samsung Cloud, to your computer, anywhere but just on the phone. This is the most important step.
- Storage: Clear off at least 5GB of space.
No update showing? Try restarting your phone. Sometimes there's a delay after you enroll. If it still doesn't show, wait a few hours and check again.
So, Should You Hit Download?
Go for it if... this is a hobby for you. You have a second device. You enjoy reporting bugs and don't mind when your banking app crashes for no reason. Your feedback actually helps.
Stay away if... this is your only phone. You need it for work, for family, for anything reliable. Wait for the final, public version. The beta isn't for you, and that's okay.
Frequently Asked Questions
I have a Galaxy Z Fold6/Flip6. Can I join this beta?
Nope. According to the info available, this beta is only for the Galaxy Z Fold7, Z Flip7, and S25 series. Older foldables aren't on the list.
Will installing the beta wipe my data?
The installation process itself shouldn't erase anything. But because the software can be buggy and might force you to reset later, a backup is non-negotiable.
Can I roll back to stable One UI 8.0/8.1 if I don't like the beta?
You can, but it's messy. Rolling back from a beta to a stable public release almost always requires a full factory reset. That means wiping your phone clean.
When will the stable One UI 8.5 update be released?
Nobody's saying. Samsung hasn't provided a public timeline for the final release.
Will all Galaxy AI features in One UI 8.5 be available in India?
Probably not. Samsung often restricts specific AI features by region. The Indian version might lack some tools available in the US or Korea.
Is the February 2026 security patch included?
Yes. The current One UI 8.5 beta builds for the Z Fold7 and Z Flip7 include the February 2026 Android security patch.
The Takeaway
Samsung putting its latest foldables in the beta ring is a good sign. It means the company knows software for bendable phones can't be an afterthought, it needs specific tuning. That 4.2GB file is promising a real overhaul, not just a coat of paint. For users in India, being in the first test group is a rare bit of priority. But don't mistake access for stability. This is raw, unfinished code. Install it to explore and report bugs, not to get a sneak peek at a polished product. For everyone else, the waiting game is the smart play. The final software will get to India, but history says it'll arrive on its own, slightly delayed schedule.
