Samsung has opened the One UI 9.0 beta for the Galaxy S26 series, and the update is based on Android 17. That means Galaxy S26 owners get early access to Google’s latest platform changes, plus Samsung’s own additions, including new Galaxy AI features, DeX tweaks, and gaming tools.
The timing is classic Samsung beta behavior: early access for the newest flagships, wider rollout later if the software behaves itself. That means Galaxy S26 owners get the shiny bits first, while everyone else gets to wait and watch the bug reports pile up on the internet for a while.
Android 17 features inside One UI 9.0
Because One UI 9.0 sits on Android 17, Samsung users will see the operating system changes Google has baked in as well. The source mentions a system-level contacts picker and Advanced Protection Mode, which point to a broader push toward tighter privacy and safer app permissions.
That base matters. Samsung can add polish on top, but the underlying Android release usually decides how much room there is for the company to differentiate without breaking things. A cleaner permission flow and stronger device protection are the sort of changes most people only notice when they badly need them.
Galaxy AI, Quick Panel and DeX changes
Samsung is also extending its own feature set. The company says Galaxy AI gets new and enhanced functions, while the Quick Panel customization introduced in One UI 8.5 has been expanded further in One UI 9.0.
For people who actually use a phone like a work machine, DeX gets a small but practical tweak: moving an app window from one desktop to another is now easier. It’s the kind of change that sounds tiny on a slide and saves a few annoying seconds every day, which is usually how good software improvements work.
Game Booster gets new settings
Gaming is getting a refresh too. Samsung says Game Booster now includes new settings aimed at improving the mobile gaming experience, though it stops short of spelling out every option in this first beta release.
That leaves the usual question hanging over any Samsung beta: how much of this survives the testing phase untouched? The company has packed in enough visible changes to make the update feel substantial, but the real test is whether the final build lands on time and without the usual beta-era wobble.
