The One UI 9.5 beta looks close. A test build for the Galaxy S26 Ultra was spotted on November 4, 2026, which usually means Samsung is getting ready to open a public beta.
Samsung hasn’t announced anything yet, so the dates below are estimates, not promises.
Here are the quick facts so far:
- A One UI 9.5 test build for the Galaxy S26 Ultra showed up on November 4, 2026.
- The update is reportedly based on Android 17 QPR2.
- The beta is expected to start between late November and December, per one unofficial tracker.
- Stable release is expected in early 2027, around the Galaxy S27 launch.
- Samsung hasn’t confirmed a device list or a date.
Every item above comes from leaks and test builds, so expect some details to shift.
What the test build actually tells us
Samsung tests software on its own phones long before the public sees it. Android Authority reports that Samsung is getting the One UI 9.5 beta ready for the Galaxy S26 series, and SamMobile says the beta release is getting closer after the build appeared on the S26 Ultra.
A test build isn’t a launch. Plenty of builds get spotted and then take weeks to turn into a beta people can join.
The reported base is Android 17 QPR2. If you want a preview of the Android side, our look at Android 17 QPR2 features covers what Pixel owners get from that same release.
When could the One UI 9.5 beta start?
Nobody outside Samsung knows the exact day. The unofficial tracker SamUpdater estimates a start between late November and December 2026, beginning with the Galaxy S26 series.
That fits how Samsung ran One UI 9. The Galaxy S26 phones went first, then other models followed later. If the pattern repeats, expect a limited beta in a few countries before it widens.
The table below shows what is reported and how solid each piece is.
| Item | What’s reported | How solid is it? |
|---|---|---|
| Beta start | Late November to December 2026 | Estimate, not announced |
| First phones | Galaxy S26 series | Likely, based on the test build |
| Android base | Android 17 QPR2 | Reported, not confirmed |
| Stable release | Early 2027, near the Galaxy S27 | Expected, not confirmed |
| Official device list | Not published | Samsung may share one later this year |
The takeaway: only the test build is a firm sighting. Everything else is informed guessing.
Leaked One UI 9.5 features so far
The feature list comes from test builds, so it can change before release. These are the items showing up most often.
| Feature | What it does | Status |
|---|---|---|
| App Lock | Locks a single app behind your normal screen lock | Leaked |
| My Custom Widget | Combines data from several apps into one widget you design | Leaked |
| Interface shading | Subtle shading on widgets, bottom bars and top buttons | Reported |
| Dialer search | Adds search inside the Phone app | Reported |
| Fingerprint animation | A new animation when you unlock with your fingerprint | Reported |
App Lock is the one most people will notice. It would let you hide a banking or messaging app without locking the whole phone, which is handy when you hand your phone to a friend or a child.
My Custom Widget is the more interesting idea. If it works as described, one widget could show your calendar, weather and a task list together.
Will your Galaxy phone get One UI 9.5?
Samsung hasn’t published a list. Two unofficial lists suggest the Galaxy S24, S25 and S26 series, plus recent foldables, would be included.
The Galaxy S23 and Galaxy Z Fold 5 and Flip 5 aren’t on either list, but that’s an inference, not a statement from Samsung. A few mid-range models appear on only one list, so treat those as uncertain.
If you own a Galaxy A-series phone, wait for the official announcement before planning around it. Meanwhile, keep your phone current with the Samsung November 2026 security update.
How to get ready before the beta opens
A little prep makes any beta safer. These steps take about ten minutes.
- Back up your photos, chats and files with Samsung Cloud or Google.
- Charge your phone above 50% and free up at least 10GB of storage.
- Check that your banking and work apps don’t block beta software.
Doing this now means you can join quickly if you want to, or skip it without worry.

What is the One UI 9.5 release date?
Stable release is expected in early 2027, around the Galaxy S27, but that’s an estimate. The beta may arrive first, possibly by December.

Our take
If you own a Galaxy S26, don’t rush. Let the first beta come out, read what early testers say, and then decide. The leaked App Lock and custom widgets sound useful, but a stable build in early 2027 will be easier on your battery and your nerves.
