One UI 4 is the latest version of Samsung’s overlay for Android. It is based on Android 12, and is currently in beta for the Samsung Galaxy S21 series in a number of countries. But what is new in One UI 4? What features are coming? What devices will get the update? When will it be available to everyone?

We’ll answer all of that and so much more here. As this is everything you need to know about One UI 4.

What is One UI 4?

One UI 4 is the latest version of Samsung’s software for its smartphones, and it is based on Android 12. It was first released in Beta on September 14, 2021 to the Samsung Galaxy S21 series. It’s the fourth iteration of the software since Samsung revamped it a few years ago.

Typically, we’ll see the .1 update come with the Galaxy S devices in the Spring, and then the .5 version come towards the fall with the new foldables (previously, the new Notes). Followed by the new version with the new version of Android. So this year we saw One UI 3.1 with the Galaxy S21, One UI 3.5 with the Galaxy Z Flip 3 and Fold 3. And now One UI 4 with Android 12 is on its way.

When will it be released?

Samsung has gotten very quick with releasing updates in recent years. So while we don’t know for sure when the final, stable version will be released just yet. It would not surprise us to see it start coming out before the end of 2021 on the Galaxy S21.

It’ll likely come to the Galaxy S21 series first, followed by the new foldables (Galaxy Z Fold 3 and Flip 3) along with the other older high-end devices from Samsung. The beta will also likely expand to other devices in the next month or so.

Starting with customization. Samsung is allowing users to customize the widgets in One UI 4. You can also customize your home screen, icons, notifications, wallpapers and so much more. The redesigned widget screen offers deeper customization. Allowing you to change up the appearance.

One UI 4 also brings in some enhanced privacy and protection functions that is going to make it easier to keep your data protected. It expands on Android 12’s permissions options, and allows users to view their permissions history from the last seven days. Instead of just the last 24 hours (what Android 12 does).
