The operating system Android 9 Piereleased by Google in 2018 brought users many visual changes, including an adaptive battery and a new gesture interface. However, many smartphone owners who upgrade to this version are faced with limited default visual options. The standard shell often seems too strict or boring, which prompts you to look for ways to personalize the device to suit your taste.
The process of changing the appearance can vary significantly depending on the manufacturer of your gadget. While some brands, such as Xiaomi or Samsungprovide powerful built-in customization tools, "pure" Android requires the installation of third-party software. It is important to understand that installing themes affects not just wallpaper, but also application icons, system fonts, and sometimes the notification panel.
In this article we will analyze in detail all the available methods for changing the interface. You will learn how to use standard system tools, which launchers are best suited Android 9 and how to safely install third-party design files. Follow our recommendations to turn your smartphone into a unique device that reflects your personality.
Built-in theming capabilities in Android 9
The first step before installing third-party software should be to study the capabilities of your current firmware. Various manufacturers build their own add-ons on top of the base system, which often include full-fledged theme stores. For example, users Android 9, which often include full theme stores. For example, users Mi UI or One UI have access to huge catalogs of designs directly from the settings menu.
To find these settings, you need to go to the menu Settings and find the section responsible for appearance. It may be called differently on different devices: Themes, Display, or Personalization. If such a section is present, you can download and activate the theme in a couple of touches without risking system stability.
However, if you have a smartphone with a “clean” Android, for example, series Google Pixel or Moto, built-in capabilities will be extremely scarce. In such cases, the system only allows you to change the wallpaper and, in rare cases, the accent color of interface elements through the function Dark theme. For deep customization, additional tools will be required here.
⚠️ Attention: Built-in themes from the manufacturer are often the best optimized. Third-party solutions may incorrectly display system notifications or quick access menus on specific shells.
You should not ignore the standard settings, as they guarantee maximum compatibility. Using native tools eliminates the risk of conflicts between system processes and visual design. This is especially important for devices with a small amount of RAM.
Before downloading any theme, check the date of its last update. Themes that have not been updated for more than a year may not work correctly on current builds of Android 9.
Using third-party launchers to change the style
The most universal way to change the appearance Android 9 is to install an alternative launcher. The launcher replaces the desktop, app drawer, and often widgets, allowing you to apply thousands of pre-made styles. Popular solutions, such as Nova Launcher, Lawnchair or Microsoft Launcher, provide flexible settings for animation and icon grids.
After installing the launcher from the store Google Play, the system will prompt you to select a default application for the home screen. You need to confirm your choice of the new launcher for the changes to take effect. Next, in the settings of the launcher itself, you can import icon packs or download ready-made themes from the built-in catalogs.
Many advanced launchers support importing configurations. This means that you can download a customization file created by another user and instantly get an identical interface. This approach saves time on manually arranging widgets and setting up gestures.
- 🚀 Nova Launcher —a standard of speed and flexibility of settings, supports almost any icon pack.
- 🌿 Lawnchair —a lightweight launcher that imitates the interface of “pure” Android with the ability to customize.
- 🎨 Smart Launcher —automatically sorts applications into categories and offers many visual themes.
- 📱 Microsoft Launcher —excellent integration with Windows services and deep customization of the background and news feeds.
It is worth noting that some launcher functions, for example, changing the shape of system application icons, may require the presence root access or the use of special assistant utilities. Without these rights, system icons may remain in the standard style, creating visual dissonance.
Installing themes through specialized applications
In addition to launchers, there are applications that specialize exclusively in the use of themes. The store Google Play offers many such solutions, for example Theme Park or various themes from developers like Substratum (although support for the latter in new versions of Android is limited). These applications act as a layer, replacing system resources on the fly.
The installation process usually looks like this: you download the catalog application, select the design you like and click the “Apply” button. An application may request permission to access or use accessibility features to implement changes to the system. This is necessary because ADB to implement changes to the system. This is necessary because Android 9 strengthened the protection of the system partition.
Often a theme downloaded in one application requires a specific launcher to display icons correctly. Always read the theme description before downloading to ensure compatibility with your current software set.
⚠️ Warning: When installing themes through third-party applications, be careful about the requested permissions. Avoid apps that require access to contacts or SMS without a clear need for the theme to work.
Some applications offer paid content or a subscription to access premium themes. Before purchasing, it is recommended to use a trial period, if available, to evaluate the quality of rendering of interface elements on your specific screen resolution.
Why are some themes not fully applied?
This is often due to Android 9 security restrictions that prohibit changing system resources without superuser rights. In such cases, only icons and wallpapers are used, and the system colors remain standard.
Manual installation of themes and icon packs
For advanced users who want a unique design that is not available in stores, there is the option of manual installation. This method involves downloading theme files in the .mtz format (for some shells) or archives with icons. Files are usually distributed on thematic forums, such as 4PDA or XDA Developers.
To install such a file, you may need a file manager with access to system folders or a special theme installer application. The process involves copying files to /system/fonts or /data/system/themedirectory, which is often impossible without obtaining Root access. Without superuser rights, manual installation is limited only to changing wallpapers and icon packs through supported launchers.
If you use the method with ADB (Android Debug Bridge), then installation occurs through a computer. You connect your smartphone via USB, enable debugging and enter commands to apply the package. This is a safer method than directly editing system files, since it is reversible.
adb install theme-package.apk
adb shell pm grant com.android.theme.com.mypackage android.permission.WRITE_SECURE_SETTINGS
Manual installation gives maximum freedom, but requires technical literacy. An error when copying files can lead to the interface becoming unreadable or some elements disappearing. Always create a backup copy of your data before starting such manipulations.
☑️ Preparing for manual installation
Customizing the dark theme and accent colors
Android 9 Pie brought with it native support for the dark theme, which should not be underestimated when customizing the appearance. Activating this mode not only saves battery power on screens like AMOLED, but also radically changes the perception of the interface, making it more modern and contrasty.
You can enable the dark theme through the quick settings panel or in the menu Settings → Display → Theme. In some shells, this allows you to invert colors not only in the system menu, but also in supported applications. This creates a cohesive visual style without the need to install heavy third-party themes.
In addition, Android 9 It is now possible to customize accent colors for controls. Although this feature is not as developed as in newer versions Android 12+, it allows you to select the base shade that will be used for sliders, buttons and switches.
| Setting type | Where to find | Impact on the system | Requires reboot |
|---|---|---|---|
| Wallpaper | Desktop / Settings | Home screen and lock background | No |
| Dark theme | Settings → Screen | Invert interface colors | No |
| Icon pack | Launcher settings | Appearance of application shortcuts | No |
| System font | Settings → Display | Displaying all text in the system | Frequently yes |
Combining a dark theme with bright accent colors allows you to create a stylish and ergonomic interface. This is especially true for using a smartphone in low-light conditions, when a bright white background can tire the eyes.
The native dark theme in Android 9 is the most energy-efficient way to change the style, which does not require installing additional software.
Possible problems and ways to solve them
During the customization process, users may encounter a number of technical issues problems. The most common of them is the “flashing” of settings after rebooting the device. This often happens if the theme was not applied correctly or the launcher was not set as the default application.
Another common problem is screen resolution incompatibility. A theme designed for a 16:9 aspect ratio smartphone may appear stretched or cropped on modern 19:9 or 20:9 screens. In such cases, it is recommended to look for themes marked “Universal” or adapt them manually through the launcher settings.
If, after installing the theme, the smartphone starts to work slower or the interface jerks, the theme is probably too heavy for your processor. Complex animations and live wallpapers consume significant resources GPU. In this case, you should return to static images and simplify the visual effects.
⚠️ Attention: If, after installing the theme, the device stops responding to touches or is stuck on the loading screen, try booting into safe mode. Typically, this requires holding down the power button while turning on the phone.
You can use system logs or performance monitoring applications to diagnose problems. This will help you understand which theme element is causing a conflict with system processes Android 9.
How to enter safe mode?
On most devices, you need to hold down the power button, and then hold down the “Turn off” option on the screen for a long time until a request to enter safe mode appears. In this mode, only system applications are loaded.
