Review of Samsung One UI 3.0 – The 7th Version of Samsung’s Proprietary User Interface

One UI 3.0, the seventh version of Samsung’s proprietary user interface, was recently made publicly available to some flagships with changes to the Notification Center, quick settings, and user experience.

When it comes to the dedicated user interface on Android phones, the name of Samsung comes to mind as one of the first pioneers in this field; The company, which has released several versions of TouchWiz, Samsung Experience and One UI in the past, has now made One UI 3.0 available to the public in its latest effort.

According to Samsung, One UI 3.0 could well summarize all the existing innovations and take the Android 11 user experience to new heights. “Notification Center”, “Quick Settings”, “Icons”, “Lock Screen”, “Settings”, “Sound Adjustment Menu”, “Animations” and “Notifications” are the sections that have seen the most changes.

Notifications center and quick settings

Notification Center has also undergone changes to Samsung’s new user interface in line with Android 11. Each of the received notifications is now displayed in a separate tab, each of which, following the new One UI design language, has more rounded corners than before, so the user will have a smoother path to find a private notification.

Unlike before, now the order of display of notifications is not based on time and the notifications are prioritized depending on the sender application; For example, messenger notifications and direct messages have a higher priority than various applications. Of course, Samsung does not delegate the task of prioritizing ads to the device alone, and the user can change the priority between applications.

Quick Notification Center and Settings in One UI 3.0

By opening the quick settings page, you will notice changes in this section, such as moving the clock and date from the top left corner to the middle of the page, changing the appearance and location of the Media and Devices keys, reducing the rows of icons from four to three rows, moving buttons “More”, “Settings”, “Power Button” and “Search” and reduced background transparency are some of the changes in this section.

Thanks to the mentioned changes, the quick settings page looks more private than the previous version. It is quite clear that Samsung is trying to simplify the work by reducing the number of rows of shortcuts, which can be considered a success of the Koreans. On the other hand, in the previous version of One UI, the small size and improper placement of the “Devices” and “Media” buttons caused the user to lose focus; But now their larger dimensions and new location make them more likely to be used more.

New icons

Samsung has also imperceptibly changed the icons of the new version of its user interface. The matte background, as part of the One UI 3.0 design language, is also visible in some elements, such as PIN Lock numbers.

In the new version of One UI, a limited number of icons have been changed; Of course, we also think this strategy is right; Because in this way, without creating confusion for the user, more uniformity is created between the user interface icons.

Lock screen

The lock screen is one of the few screens that we encounter at least once with each use of the phone . Samsung has also made some exciting changes to the lock screen of the new version of its user interface.

Lock screen changes and widgets

Previously, if you wanted to control the playback of a multimedia file from the lock screen, you had to slide your finger to the top left corner of the screen; But now Samsung makes it easier for those looking to use the phone with one hand by placing this section in the middle of the lock screen.

By tapping the clock widget on the lock screen once, you can access the widget of other software that was not previously available on the lock screen in One UI.

For fans of the Always On Display‌ feature, you can select a GIF for more personalization so that the user can have more than just hours and recent announcements on this page.


In One UI 3.0, Samsung has not left the settings software unchanged. Although few, the Koreans have tried to make them easier to access with one hand by moving several menus in various settings. On the other hand, the search in the settings is now smarter than before, and the software displays the closest result to the searched word to the user by recognizing the tapi error.

Access to the required information on the battery settings page is another change made in this section. The user will now have access to a usage report as soon as they enter the accessibility section; While to view the same report in the previous version of One UI, the user had to go further.

Sound setting menu

By increasing / decreasing the volume of the device, we see the use of Samsung’s new design elements, namely rounded corners and matte background; However, the use of a slider that does not follow the language of other sliders, such as the screen brightness slider and the multimedia player slider, reduces the integrity of the user interface design.

Moving the volume adjustment slider from the top to the right side of the device can be considered a smart move; Because it makes it easier for honest people who are accustomed to using the phone evenly.

New and smooth animations

Undoubtedly, animations can be mentioned as one of the most effective parts in the user experience, which has also undergone changes in One UI 3.0.

You may not notice any changes to Samsung’s animations when using Samsung’s new interface; But if you want to compare the new version with the previous version, you will clearly feel the changes made to the animations, which have made them faster, smoother and different.


The new version of Samsung’s proprietary user interface for the galaxies is based on the 11th version of the popular Android operating system, from which we will focus on One UI 3.0 fidelity to the features of the latest version of Google’s operating system.

Announcements are one of the most variable parts of Android 11; Separate dialogs and prioritize dialog notifications over other notifications, and the Bubble feature is one of the features that One UI 3.0 inherited from Android 11.

The importance of conversations in today’s communications is also evident in the new version of One UI‌. Now, by opening the Notification Center, your incoming notifications will be divided into two sections, Conversations and Notifications, which also has a section for conversations with features such as smart response.

The Bubble feature is also a new feature that Facebook Messenger users used to know as Chat Head. Thanks to this feature, the user’s conversations in various messengers will now be in the form of a floating bubble in the user interface to make it easier to access.

Other changes

If we take a closer look at the new version of Samsung One UI, more microscopic changes such as the ability to change the background of calls, more details in the Gallery software, a more private shortcut menu of each software, the ability to add a software widget to the home screen. You will notice on the page that all of them, however small, have an impact on your user experience.


In short, One UI 3.0 can be considered a simple version, with minor changes and optimized for working with one hand, which changes, in addition to improving the user experience, has made it a more integrated user interface.

Samsung’s efforts to optimize its proprietary user interface for one-handed operation are commendable; But One UI is still not optimal for leftists; Because most buttons, sliders, and features tend to be on the right side of the screen.

Rounded corners and backgrounds that highlight the underlying content add even more to the One UI’s visual appeal . On the other hand, Samsung has respected the changes of Android 11 in One UI 3.0, and we owe the public presence of the outstanding features of Android 11 in the new version of Samsung’s proprietary user interface to this respect from Samsung.

Of course, although Samsung has in many cases made changes to Android 11 in the new version of One UI, some changes, such as new buttons added to the Power Off menu, are still not visible in this version of the Samsung UI.

Samsung’s cautious changes to One UI 3.0 have enhanced the user experience without major changes and made the user interface more integrated. There are a handful of bugs that make the Samsung One UI something close to ideal; But One UI 3.0 can hardly be considered a proper update.
