This is One UI 3.0 on the Galaxy S20

Google released the stable version of Android 11 for its Pixel smartphones last week, but for most Android users, the wait continues. The largest smartphone maker in the world, Samsung, has yet to officially announce the latest version of its Android-based software called “One UI,” even though they quietly opened pre-registrations for a One UI developer program last month. 3.0. Registrations for this closed beta program for developers were released in South Korea last week, but today the closed beta was released in the United States. Thanks to Max Weinbach, I was able to put my unlocked Galaxy S20 in the US into the closed beta 3.0 of One UI, allowing XDA to give you a first glimpse of Samsung’s Android 11 update.

Note that this is a file closed beta program intended for developers, this build doesn’t have all the new One UI gadgets that Samsung has been developing behind the scenes. This build is intended to allow developers to test their apps on Android 11-based One UI 3.0 several months before it’s officially available to users. This is necessary because Samsung does broad changes to the Android framework, so an app that works on Google’s Pixel phones or Android 11’s AOSP isn’t guaranteed to work the same on Samsung’s Android 11 software. Finally, many of the new features mentioned in the change log are actually changes made to Samsung apps rather than the operating system itself.

News of the closed beta of Android 11 on Galaxy S20

Before I dive into the news, I think you might take a look at the official change log:

When you first install the One UI 3.0 beta, the first thing I think you’ll notice is the redesigned Quick Settings / Notification panel. Like OPPO, Samsung has adopted to apply a Gaussian-like blur effect behind notifications. Personally I’m a big fan of this change because I think it’s beautiful. Not everyone is going to like this blur effect, so hopefully Samsung will add an option (perhaps in a Good Lock module?) To turn it off.

The next change you may notice is the new volume panel design. It’s a vertical volume slider that expands horizontally to reveal more vertical sliders for other volume streams. There is also a switch for Live Caption as the Galaxy S20 supports it, although this switch will not appear on all Samsung Galaxy devices that receive the One UI 3.0 update. Samsung users on older versions of One UI can download the SoundAssistant app to enable a vertical volume slider.

Here is a side by side of the Settings pages in light and dark themes:

And here’s a gallery of the lock screen, home screen (with a flattened warning notification displayed at the top), and overview of recent apps. To be clear, these screens are mostly unchanged, except for a slight change to the recent apps overview where the currently focused tab is zoomed in slightly.

Next, let’s talk about the stock Android 11 features that Samsung did (and didn’t add). Since Android 11 is open source and licensed with Apache version 2.0, OEMs have the freedom to tweak Android to their liking. However, to pass Google’s Android compatibility requirements and thus preload Google Mobile Services, OEMs need to implement a couple of Google’s Android 11 features. This includes one-time bills and permissions but doesn’t include features like Device Controls, Quick Access Wallet, Media Controls in Quick Settings, or Conversations in Notifications. Fortunately, Samsung has implemented most of these features anyway.

Unfortunately, Samsung has not implemented the Device Controls feature in its One UI 3.0 beta. This feature would turn the power menu into a smart home control center. One UI already has its own shortcut to access smart home products (open the Quick Settings panel fully and tap “Devices”), but it only works with Samsung’s SmartThings app. Device Controls is a more open API on the contrary. In addition, it also lacks the Quick Access Wallet feature which allows you to quickly change your current Google Pay card, although Samsung already offers its own method to quickly change Samsung Pay cards.

Here is a screenshot gallery showing most of the various settings pages, in case you want to compare with One UI 2.0 / 2.5 on your device.

Here is a gallery showing some of the new features of the One UI 3.0 beta. These features include a new “minimal battery use” mode that applies a dark theme, a minimal home screen and restricts apps for maximum power savings, a new “advanced processing mode” that improves performance, easier access to Samsung keyboard settings in Settings> General Management, wireless DeX (if your device did not receive it in the One UI 2.5 update) and custom call wallpapers.

Bixby Routines is getting some nice updates. You can now apply a custom icon for each routine, see which actions are undone when a routine ends, activate various accessibility features, activate Bixby, use new conditions including specific time, Wi-Fi network, Bluetooth connection, and incoming calls from a specific contact or from any contact.

Samsung’s implementation of Personalized Digital Wellbeing has some features you won’t find in Google’s version. These include setting a screen time goal, viewing phone usage trends in weekly reports, viewing phone time usage while driving, and adding a widget to the lock screen to quickly view screen usage time.

Right after upgrading to One UI 3.0 beta, I got some updates for stock Samsung apps from the Galaxy Store. The Samsung Gallery app now allows you to undo the changes you’ve made, the Samsung Messages app has added a trash can to store your deleted messages, the Contacts app helps you quickly delete duplicate contacts, and more.

Samsung Internet 13.0 is preloaded on One UI 3.0. It includes features like the ability to lock / reorder tabs, prevent pages from hijacking the back button, alerts on malicious sites, hide the status bar when scrolling, and more.

A couple of changes have also been made to the stock One UI Launcher. For example, the context menu has been redesigned and includes an option to place an associated widget by long pressing on an app icon. There’s also a new “double-tap to sleep” option that lets you turn off the screen by double-tapping any blank area of ​​the screen, although this gesture must be enabled in Settings> Advanced Features> Gestures & Gestures.

The Samsung Keyboard app supports inline autofill and copy-paste image suggestions. However, the new emojis of Android 11 are missing.

Finally, here is a screen recording of our friend Rydah (@SamsungRydah) showing the new animations in the beta of One UI 3.0.

These are all the changes I encountered during my short practice test of the One UI 3.0 closed beta on the Galaxy S20. I’m sure Samsung will have a lot more to show us by the end of the year when they are actually ready to unveil their Android 11 update. Of course we will continue to dig into this release to see if there are any other undocumented changes in the change log. .

How to install One UI 3.0 (closed beta) on US / Korean Galaxy S20

If you are curious, it is possible to install the closed beta on a US or Korean Galaxy S20 series device if you have installed the Samsung Members app and use a direct link to access the correct screen. This is how several people, including us, got access to the beta. Thanks to Max Weinbach for initially discovering this method.
