Samsung One UI and Android 9 Pie update: Everything you need to know

When you update your Samsung phone to Android 9 Pie or buy a phone like the Galaxy S10, you may notice that things look a bit different. That's because there's a lot going on! In addition to the usual Android Pie features, Samsung customized this version of Android to create a new interface for its phones that it calls "Samsung One UI."

Ready to learn all about One UI and see just what it has to offer? Here's everything you need to know!

What exactly is One UI?

One UI is the name of Samsung's latest Android interface and serves as the successor to The Samsung Experience that previously replaced TouchWiz.

One of the biggest goals with One UI is to help users "focus on the task at hand." To achieve this, One UI removes a lot of clutter from the Samsung Experience and makes things much cleaner. For example, the settings page is simplified even more and regrouping certain settings together so that they're easier to get to. The phone, notes, email, and other Samsung apps also have a new look to only show essential information.

Samsung's also marketing One UI as being more natural, saying that it's "restructured the way we interact with our devices." Buttons that are traditionally towards the top of the screen have been moved closer to the bottom, and in many of Samsung's apps (such as Messages and Clock), the top area is reserved exclusively for viewing content you don't have to interact with.

Third, One UI aims to "be visibly comfortable." Colors have been tweaked to provide better clarity, and based on the color of the phone you have, elements of the UI will be tweaked to match it.

There's a pretty sweet dark mode

Dark mode isn't a thing in Android Pie by default, but with One UI, Samsung picked up Google's slack and added a pretty great one for its phones.

It's pretty easy to enable One UI's dark mode, requiring you to just hop in the settings and enable a couple of toggles. Once you do this, you'll get a sleek dark theme all over your phone — including things like the notification panel, settings page, and Samsung's own apps.

One UI's dark mode doesn't have any impact on third-party apps you download from the Play Store (Twitter, Amazon, WhatsApp, etc.), but that doesn't stop it from being a thing of beauty.

What Android version is it based on?

One UI is based on Android 9 Pie, and as such, has all of the features from Pie that we've come to know and love.

That means One UI has some new gesture navigation options, a bunch of new emoji, improved notifications, and more on top of all of the One UI-specific changes.
