Samsung One UI 4.0: Latest News, Eligible Devices, Features and Release Date



One UI 4

Based on the Android operating system, Samsung One UI is the best ever custom skin among all the OEMs. From the Android 9-based One UI 1 to the latest Android 11-based One UI 3, the Korean tech giant introduced tons of new changes, features, and improvements with every iteration of the One UI.

Back in December 2020, the company has officially launched the third major generation of One UI – One UI 3. The One UI 3 is based on Google’s Android 11 (the eleventh major generation of the Android operating system). With this version, Samsung has totally modified the user interface and added several iconic functions.

At the same time, Samsung started releasing the stable Android 11-based One UI 3.0 software update for the Galaxy S20 series smartphones, as promised.

Meanwhile, a large group of phones/tablets is waiting to get the Android 11 update.


Like every year, the South Korean tech giant unveiled the new Galaxy S series smartphones on January 14, 2021.

One UI 4.0

As Google has finally released the Android 12 to AOSP, every Samsung fan knows, the next generation of One UI will be called One UI 4.0. However, this iteration of One UI will be based on the Android 12 operating system. We can expect, just after the stable release of the Android 12, Samsung will announce the One UI 4.0 around September/October this year.


One UI 4.0 Release Date – November 15, 2021

The stable Android 12 launched in October 2021 for Google Pixels. Following this, Samsung began the One UI 4.0 beta program for flagship Galaxy devices. Besides, the Galaxy S21 flagships became the first to be invited for the One UI 4.0 beta activity in late August. However, the company may start delivering the stable One UI 4.0 to these phones from November/December this year.

November 15, 2021

Samsung officially launched the stable One UI 4.0 software system based on Android 12 operating system. The company said that the One UI 4.0 update rollout will begin for the Galaxy S21, Galaxy S21+ and Galaxy S21 Ultra phones from now on. Read more

Samsung One UI 4.0: Features

Based on Android 12, the One UI 4.0 delivers even more personal, safe and effortless experiences on your device. Featuring a totally reimagined interface just for you, new privacy features that are designed for your safety and put you in control, and more seamless ways to get right to your gameplay or even switch to a new device.


Personalization – Starting with Android 12 on Pixel devices, you’ll be able to completely personalize your phone with a custom color palette and redesigned widgets. Using what we call color extraction, you choose your wallpaper and the system automatically determines which colors are dominant, which ones are complementary and which ones just look great. It then applies those colors across the entire OS: the notification shade, the lock screen, the volume controls, new widgets and much more.

Fluid motion and animations – From the moment you pick up an Android 12 device, you’ll feel how it comes alive with every tap, swipe and scroll. Your phone quickly responds to your touch with smooth motion and animations.

We’ve also simplified interactions and recrafted the entire underlying system to make your experience more fluid and efficient. Your Android devices are now faster and more responsive with better power efficiency so you can use your device for longer without a charge.


This was achieved by some under-the-hood improvements including reducing the CPU time needed for core system services by up to 22% and reducing the use of big cores by the system server by up to 15%.

Redesigned system spaces – Some of the most important spaces on your phone — like your notification shade, quick settings and even the power button — have been purposefully reimagined to help you get things done.

The notification shade is more intuitive and playful, with a crisp, at-a-glance view of your app notifications, whatever you’re currently listening to or watching, and Quick Settings that let you control practically the entire operating system with a swipe and a tap.


The Quick Settings space doesn’t just look and feel different. It’s been rebuilt to include Google Pay and Home Controls, while still allowing for customization so you can have everything you need most in one easy-to-access place.

To make sure you always have help from Google at your fingertips, you can now long press the power button to invoke Assistant to make a phone call, open apps, ask questions or read aloud text-heavy articles.

Private and secure by design – Android 12 includes new features that give you more transparency around which apps are accessing your data, and more controls so you can make informed choices about how much private information your apps can access.


The new Privacy Dashboard offers a single view into your permissions settings as well as what data is being accessed, how often and by which apps. It also lets you easily revoke app permissions right from the dashboard.

We’ve added a new indicator to the top right of your status bar so you know when your apps are accessing your microphone or camera. And if you want to remove app access to these sensors for the entire system, we’ve added two new toggles in Quick Settings.

We’re also giving you more control over how much information you share with apps. With new approximate location permissions, apps can be limited to seeing just your approximate location instead of a precise one. For example, weather apps don’t need your precise location to offer an accurate forecast.

Aside from flagships, Samsung also has a number of mid-range, budget, and entry-level devices that belong to the Galaxy A, Galaxy M, and Galaxy F series. It’s worth mentioning that select premium Galaxy A phones get three Android upgrades just like the flagships, while others get two.


Starting Galaxy A72 (most premium Galaxy A phone) to the Galaxy A02 (cheapest Galaxy A phone), around a half dozen of Galaxy Ax2 smartphones are eligible for the Android 12-based One UI 4.0 upgrade. You can check their list below.

Note: Galaxy Ax1 models are also eligible for Android 12 One UI 4.0 update.

Ahead of the major Android switch, all of the above-listed phones will also get the new One UI 3.1.1 update that will also be based on the current Android 11 OS. Instead of the One UI 3.5, the 3.1.1 version of One UI will make its market debut this August.
