Samsung did a fantastic job with the One UI 3.1 update based on Android 11 to most phones in its portfolio, and with Android 12, it is aiming to outdo itself. Samsung’s Android 12 update is One UI 4, and it comes with a slate of new features and a UI refresh. While the design itself isn’t too different to the current One UI 3.1, there’s a lot to be excited about — Samsung is using a version of the colorful Material You design aesthetic called Dynamic Color to offer much better customization, and there are 60 new features in total.

The best part is that the One UI 4 stable update is now rolling out, with Samsung delivering the update just a month after Google released the Pixel 6 series. The One UI 4 stable build is now available for the Galaxy S21 series in select countries, so let’s find out what Samsung has to offer with Android 12, what phones will get the update, and a look at the new features.

Still the flagship to beat

The Galaxy S21 Ultra combines the latest display and hardware innovations to deliver a flagship that truly stands out from its rivals. You get a sublime 120Hz AMOLED screen backed by the latest internal hardware, incredible cameras, all-day battery with fast charging, and software that’s highly customizable. If you want to be the first to try out One UI 4, you’ll need to switch to the S21 Ultra right now.

Samsung has kicked off the One UI 4 stable build

On September 14, Samsung announced the first One UI 4 public beta for the Galaxy S21 series. Like previous years, the beta was limited to the latest Galaxy S flagship, giving owners of the Galaxy S21, S21+, or S21 Ultra an early look at the changes. Samsung rolled out the second Android 12 beta on October 5, bringing Google’s Material You’s color extractor feature and bug fixes. The third and fourth betas were made available in subsequent weeks with bug fixes.

After two months of testing, Samsung started rolling out the stable One UI 4 build from November 15. The Galaxy S21, S21+, and S21 Ultra are now receiving the stable version of Android 12 in select markets, and the build will make its way to all devices globally over the coming days.

Samsung makes the best Android phones you can buy today, and the fact that it rolled out the Android 12 stable build just a month after Google shows just how much the Korean manufacturer has changed in this particular area over the last three years. With the Galaxy S21 series already receiving the update, the focus has shifted to other devices in Samsung’s portfolio; most of these phones will start shifting to One UI 4 over the coming weeks and months.

One UI 4 is getting a lot of new features

With One UI 4.0, Samsung is introducing a host of new features and updating the interface. While One UI 3.1 featured a few refinements over One UI 2.0, the interface was left largely unchanged, so we are due for an update in this area. The first beta doesn’t have too many changes in terms of design, but according to leaker chunvn8888, Samsung will unveil an updated color palette and new icons, and use Android 12’s Material You design aesthetic.

Samsung took the best bits of Android 12 from Google and added its own flavor.

We’re seeing that with the second beta release. One UI 4 beta 2 includes the Material You color picker that lets you pick system colors based on your phone’s background. It is a really cool addition, and while the effect isn’t as extreme as what you’ll find on Google’s own devices, it is still an interesting new feature that will get a lot of usage.

There are exciting changes elsewhere; the brightness slider on the notification pane is larger than before, making it easier to use. It is thankfully not as oversized as the one on the Pixels, with Samsung maintaining the right balance. One UI 4 also enables eSIM for Galaxy S21 models in the U.S.

In terms of privacy and security, One UI 4 gets a nifty permission usage history that lets you see what permissions have been accessed. The location permissions window has a new interface that’s similar to what you’ll find on Android 12, and like the Pixels, you get the ability to turn off camera or mic access system-wide with a single toggle. And Samsung also added a green recording indicator whenever your camera is in use, ensuring no errant service in the background enables access without you knowing about it.

As for interface changes One UI 4 has a new widget picker, cleaner design for toast notifications, and a new interface for disabling notifications directly from the pane. And a useful accessibility feature is the ability to set custom colors for each individual app’s notifications. You can set an AR emoji as your profile photo for your Samsung account.

The camera is also getting an overhaul with One UI 4, with Samsung offering a cleaner design, video recording that starts the moment you press the Record button, tweaks to the Single Take feature and Pro mode, and zoom levels on the lens icons.

Samsung confirmed a few weeks ago that it will be getting rid of ads within One UI, and it is starting to do that right now. Another major feature in One UI 4 has to do with under-the-hood tweaks, with Samsung optimizing the UI to take full advantage of high-end hardware like the Snapdragon 888 and Exynos 2100. Samsung has done much better in this regard in the last two years, but its flagships and most of its mid-range devices now offering 120Hz panels, any UI optimizations will make a noticeable difference.

Here’s the full changelog for One UI 4
