Interface personalization is not just entertainment, but a way to make interaction with the device more intuitive and enjoyable. Owners of devices from the Korean giant have a unique advantage: a powerful standard customization tool that does not require superuser rights. Creating your own theme allows you to combine your favorite colors, fonts and logos into a single ecosystem that works stably and without errors.
Many users mistakenly believe that in order to deeply modify the appearance, third-party software or complex manipulations with system files are required. However, the built-in platform Samsung Galaxy Themes provides sufficient functionality to assemble your unique design in just a few minutes. It is important to understand that you are not working with code, but with a constructor, where each element can be edited.
In this guide, we will analyze all the stages: from choosing a basic style to fine-tuning controls. You'll learn how to change not only your wallpaper, but also the shape of application icons, the color of system menus, and even the behavior of the lock screen. The finished result will work at the system level without consuming extra battery, as is often the case with third-party launchers.
Preparing tools and choosing a basic style
The first step is to activate the required module in the system. On modern smartphones of the Galaxy S i Galaxy A series, the application is preinstalled by default. You need to find it in the menu or search by name Galaxy Themes. If the icon is missing, you can download it for free from the store Galaxy Store, which is the only legal source of add-ons for the Samsung interface.
After launching the application, the system will prompt you to select a basis for future work. You can start with a blank slate, but it is much more effective to find a ready-made template that is close to the desired result. In the "My Pages" or "Categories" sections, you can often find free themes with a minimalistic design that are ideal for modification.
⚠️ Attention: Make sure your device is updated to the latest available version of One UI. Old versions of the firmware may not support new font or widget formats, which will lead to incorrect display of the theme you created.
The selected base determines the structure of the menu and system windows. Key point at this stage we check the compatibility of elements. Some complex themes may block the ability to change individual components, so try to select options marked "Edit" or "Customize".
- 📱 Launch the application
Galaxy Themesfrom the settings menu or Samsung folder. - 🔍 Use search by query "Simple" or "Basic" to find an easy basis.
- 🎨 Click the "Customize" button under the selected theme to enter the editor.
- 💾 Save the draft, giving it a temporary name so as not to lose progress.
Setting the lock screen and Always On Display
Lock screen - this is the first thing the user sees when the display is activated. In the theme editor, Samsung allows you to completely rework this layer. You can change the location of the clock, choose a different font for the date, and add useful widgets such as steps or weather.
It is worth paying special attention to the function Always On Display (AOD). If your screen supports this technology, the theme can include a static or animated image that is visible even in sleep mode. The editor allows you to choose the backlight color and time display style so that they are in harmony with the overall style.
Settings → Wallpaper and style → Lock screen → Clock styleIt is important to maintain a balance between beauty and readability. Too bright colors or complex patterns can interfere with quickly reading the time. The optimal solution It is considered to use contrasting colors for numbers and a muted background.
Use dark colors for the lock screen if you often use your phone at night. This will reduce eye strain and save battery power on AMOLED screens.
Editing the application bar and icons
The most noticeable part of any theme is the application icons. The built-in editor offers to change their shape, background color, and even replace sets with custom ones. You can choose standard round or square icons, or download your own package from Galaxy Store.
When creating a theme, it is important to consider that not all applications have their own unique icons in the system. For such cases, there is a "Default Icons" feature that automatically generates placeholders based on the color of the main theme. This allows you to maintain the visual integrity of the interface.
| Parameter | Description | Impact on the system |
|---|---|---|
| Icon shape | Circle, square, rounded square | Changes the appearance of all applications |
| Background color | Gradient, solid color, transparent | Affects readability in folders |
| Grid size | 4x5, 5x5, 5x6 | Defines the number elements |
| Signature font | System or downloaded | Affects the style of the text under the icon |
Don't forget about folders. When creating a theme, you can set the background color for folders and the style of opening them. This is a small thing that significantly improves the perception of the interface. Changing the size of the desktop grid may require rearranging widgets, so do this at the beginning of the process.
Working with the notification panel and quick settings
The Quick Panel is the area where the user looks most often. The Theme Editor allows you to change the background color of this panel, the color of the brightness and volume sliders, and the style of the switch buttons.
You can make the panel translucent or completely matte. You can also customize the color of activity indicators. For example, if Bluetooth is turned on, the icon may not light up in the standard blue, but in a shade of your choice that matches the overall color scheme.
- 🔘 Change the style of the switch buttons to "Outline" or "Filled".
- 🌈 Select a panel background color that contrasts with the wallpaper.
- 🔊 Adjust the color of the sound adjustment sliders.
- 📶 Check the display of network indicators in different modes (4G/5G/Wi-Fi).
It is worth noting that some system colors may ignore theme settings for the sake of accessibility. This is done to ensure that important notifications always remain visible. System restrictions One UI does not allow you to change critical security elements.
Why do some buttons not change color?
The Android system prioritizes colors for important actions (such as mute or emergency calls) that cannot be changed through the standard theme editor to avoid user confusion.
Customizing the settings menu and system windows
Deep customization also applies to internal menus. You can change the background color of the settings list, the color of headers and separators. This creates an immersive experience where the entire phone looks like one.
New versions of One UI have a Color Picker feature that automatically generates a theme based on the colors of your wallpaper. However, manually creating a theme gives a more predictable result. You can hardcode the colors for the light and dark themes separately.
⚠️ Attention: The settings menu interface may differ on different models. On tablets or devices with a folding screen, some elements may scale differently than on standard smartphones.
When working with text fields and buttons within settings, try not to use too light shades for text. Readability should remain at the forefront. Check how your design looks in bright sunlight.
Saving, exporting and applying the theme
After all the elements are configured, it's time for finalization. Click the "Save" button in the editor. The system will prompt you to come up with a title and, if desired, add an author. The theme will be saved in the "My Pages" section of the Galaxy Themes application.
You can switch back to the standard theme or another saved one at any time. The configuration you created will not disappear until you delete it from the device’s memory. This allows you to have several profiles: for example, “Work” and “Game.”
Menu (three bars) → My pages → Select a theme → ApplyFor those who want to share their creation, there is the possibility of publishing in Galaxy Themes. However, this process requires registering as a developer and undergoing moderation. For personal use, local saving is sufficient.
