Registrations for this closed developer beta program went live in South Korea last week, but earlier today, the closed beta went live in the United States.

unlocked Galaxy S20 into the One UI 3.0 closed beta, allowing XDA to bring you an early look at Samsung’s Android 11 update.

Keep in mind since this is a closed beta program intended for developers, this build doesn’t have all the new One UI goodies that Samsung has been developing behind-the-scenes.

This build is aimed at letting developers test their apps on Android 11-based One UI 3.0 several months before it officially rolls out for users.

This is necessary because Samsung makes extensive changes to the Android framework, so an app that works on Google’s Pixel phones or AOSP Android 11 isn’t guaranteed to work the same way on Samsung’s Android 11 software.

Lastly, a lot of the new features mentioned in the changelog are actually changes made to Samsung apps rather than the OS itself.

One UI 3 brings you Android 11 with exciting new features from Samsung and Google based on feedback from users like you.

Some apps, including Calculator, Samsung Internet, Samsung Pay, Samsung Health and Samsung Notes, need to be updated individually after you update your OS.

There’s also a toggle for Live Caption since the Galaxy S20 supports it, though that toggle won’t appear on every Samsung Galaxy device getting the One UI 3.0 update.

Next up, let’s talk about the stock Android 11 features that Samsung did (and didn’t add).

However, in order to pass Google’s Android compatibility requirements and thus preload Google Mobile Services, OEMs are required to implement a couple of Google’s Android 11 features.

That includes Bubbles and one-time permissions but doesn’t include features like Device Controls, Quick Access Wallet, Media Controls in the Quick Settings, or Conversations in notifications.

A few of the other minor changes Samsung brought over from stock Android 11 include a shortcut to Android Auto in Settings > Connections, a refresh rate overlay in Developer Options, and a wireless debugging feature in Developer Options.

Here’s a gallery showing off some of the miscellaneous new features in the One UI 3.0 beta?

These features include a new “minimal battery use” mode which applies a dark theme, a minimal Home screen, and limits apps for maximum power saving, a new “enhanced processing mode” that boosts performance, easier access to Samsung Keyboard settings in Settings > General management, wireless DeX (if your device didn’t get it in the One UI 2.5 update), and custom call backgrounds.

Immediately after I updated to One UI 3.0 beta, I received a few updates to stock Samsung apps from the Galaxy Store

Those are all the changes I found during my brief hands-on of the One UI 3.0 closed beta on the Galaxy S20

I’m sure that Samsung will have a lot more to show us later this year when they’re actually ready to unveil their Android 11 update

If you’re curious, it’s possible to install the closed beta release on a U.S

That’s how several people, including us, got access to the beta

Oh yeah, here's the secret sauce for anyone else that wants to try joining the One UI 3.0 closed beta

I follow AOSP and the Chromium Gerrit to uncover new features, and I also routinely analyze Android applications and device firmware to do the same
