Android smartphones offer many ways to personalize the appearance of a device. Users can change wallpapers, adjust colors, install icon packs, customize home screens, and use different launchers. Android Pie, also known as Android 9, introduced several design improvements that made the Android experience cleaner and more convenient.
If you are searching for themes Android Pie, you may want to give your older smartphone a fresh appearance without purchasing a new device. You might prefer a dark interface, colorful icons, a Pixel-inspired home screen, or a simple material design.
Android Pie does not provide one universal theme store that works identically across every smartphone. Theme availability depends on the phone manufacturer, software version, launcher, and supported customization tools. However, there are several ways to personalize an Android 9 device.
This guide explains Android Pie themes, their features, different customization options, supported tools, installation methods, and important compatibility considerations.
Whether you want a clean home screen or a completely different visual style, this article will help you understand your options.
What Are Themes Android Pie?
Themes Android Pie refers to visual customization options designed for smartphones running Android 9. These options can change different parts of the phone’s appearance.
Depending on the device and customization method, a theme may change:
- Home screen appearance
- App icons
- Wallpapers
- System colors
- Notification panel appearance
- Fonts
- Navigation bar appearance
- Supported application interfaces
- Widgets and home screen layouts
A theme can make a smartphone look different without changing its main operating system.
For example, someone who likes a simple interface may choose a minimal theme with a plain wallpaper and basic icons. Another user may prefer bright colors, rounded icons, and a customized home screen.
Android Pie supports the Android theme framework used by applications, but complete device-wide visual customization is not available in the same way on every manufacturer’s software.
This is why users should check their phone’s compatibility before installing a theme.
What Is Android Pie?
Android Pie is Android version 9.0. Google released it in August 2018.
The operating system introduced several improvements to the Android experience. These included gesture-based navigation, adaptive battery features, app actions, digital wellbeing tools, and a redesigned user interface.

Depending on device support, users could access features such as app timers, usage information, and Wind Down.
5. Improved Notifications
Android Pie improved notification management and introduced additional notification controls.
Users could interact with supported notifications and manage how applications displayed alerts.
These improvements made Android Pie an important release in Android’s development.
Why Do People Search for Android Pie Themes?
People search for Android Pie themes for several reasons.
Some users still own smartphones running Android 9 and want to personalize their devices. Others want the visual appearance of Android Pie on another supported Android version.
Here are some common reasons.
1. Personalization
Every smartphone user has different preferences.
Some people like simple home screens, while others prefer colorful designs and detailed widgets.
Themes provide a way to create a smartphone interface that matches personal taste.
2. A Fresh Smartphone Appearance
A new wallpaper or icon pack can make an older smartphone feel different.
Users do not always need to purchase another device to improve its appearance.
Changing the home screen layout, icons, and colors can create a noticeable visual difference.
3. Dark Interface Preferences
Some users prefer dark backgrounds because they find them comfortable in low-light environments.
Android Pie devices may offer dark interface options depending on the manufacturer and software version.
Third-party applications and compatible theme engines can provide additional customization.
4. Pixel-Inspired Design
Google Pixel smartphones are known for their relatively clean Android interface.
Some users want a similar visual experience on their existing smartphones.
Pixel-inspired launchers, wallpapers, and icon packs can help create this appearance.
5. Better Home Screen Organization
Themes and launchers can also improve home screen organization.
Users can arrange applications, widgets, folders, and shortcuts according to their needs.
Best Types of Themes for Android Pie
There is no single best Android Pie theme for every user. The right choice depends on your preferred design and the customization options supported by your smartphone.
Here are some popular theme styles worth exploring.
1. Dark Themes for Android Pie
Dark themes use darker backgrounds and lighter text or icons.
They are popular among users who prefer a darker interface.
A dark theme may include:
- Dark application backgrounds
- Grey or black interface elements
- Light-colored text
- Contrasting notification icons
- Dark wallpapers
- Matching application icons
Dark themes can also look attractive on OLED displays, although actual battery savings depend on the display technology and how the interface is designed.
Before installing a dark theme, check whether it supports your particular Android Pie version and phone manufacturer.
Some themes only change selected applications rather than the entire operating system.
2. Pixel-Inspired Android Pie Themes
Pixel-inspired themes recreate some visual elements associated with Google’s Pixel smartphones.
These themes may include:
- Simple application icons
- Google-style widgets
- Minimal wallpapers
- Clean home screen layouts
- Rounded design elements
- A simple application drawer
Pixel Theme – Substratum is one historical example of a customization project that listed support for Android 9.0 AOSP devices.
It requires the Substratum theme engine, and its compatibility should be checked before use.
A Pixel-inspired launcher can also be a simpler alternative for users who only want to change their home screen.
3. Material Design Themes
Material Design focuses on clarity, consistent spacing, colors, and recognizable interface elements.
A material-inspired Android Pie theme may use:
- Clean typography
- Simple icons
- Balanced color combinations
- Clear buttons
- Consistent spacing
- Flat or lightly layered interface elements
This design is suitable for people who prefer an organized and professional appearance.
4. Minimalist Themes
Minimalist themes remove unnecessary visual elements.
They generally use simple wallpapers, limited colors, and basic icons.
Popular characteristics include:
- Plain backgrounds
- Small icon collections
- Simple widgets
- Limited home screen shortcuts
- Clear typography
- Organized application folders
Minimalist themes are useful for users who want a clean smartphone experience.
5. Colorful Themes
Colorful themes use brighter backgrounds, attractive icon designs, and coordinated colors.
They may include:
- Blue and purple color combinations
- Bright application icons
- Gradient wallpapers
- Colorful widgets
- Custom notification accents
Users should select colors that provide enough contrast for comfortable reading.
6. Transparent Themes
Transparent themes attempt to give supported interface elements a translucent appearance.
Some Substratum themes offered transparency options for particular Android versions and devices.
However, transparent themes are highly dependent on system compatibility.
They may not work correctly on modified manufacturer software or unsupported applications.
7. AMOLED Black Themes
AMOLED black themes use pure black backgrounds.
On OLED and AMOLED displays, black pixels can turn off individually, which may reduce display power consumption when large black areas are shown.
These themes may include black backgrounds, simple white icons, and limited accent colors.
Remember that the battery benefit depends on the screen technology and actual display usage.
Popular Android Pie Theme and Customization Options
Several tools and projects have been associated with Android customization.
Their current availability and compatibility can change, so always check the latest application information before installation.
1. Substratum Theme Engine
Substratum is a theme engine that has been used to apply visual overlays to supported Android systems.
It provided a way to customize system elements and compatible applications.
Depending on the device and Android version, Substratum may require root access, a supported custom ROM, or another compatible setup.
It is not a universal one-click theme application.
Users should read the official requirements carefully before attempting to install it.
2. Pixel Theme – Substratum
Pixel Theme – Substratum is a historical customization option designed to provide a Pixel-inspired appearance.
Its published compatibility information includes Android 8.0, Android 8.1, Android 9.0, and Android 10.0 AOSP versions.
It uses the Substratum theme engine.
Potential customization areas include:
- System interface elements
- Navigation bar
- Framework
- Package installer
- Color choices
- Launcher appearance
Do not assume that it will work on every Android Pie smartphone. Manufacturer modifications and software updates can affect compatibility.
3. Alined Substratum Theme
Alined is another historical theme option with Android Pie support.
Its published description mentions light styling, line-art iconography, and dark overlays for selected applications.
The developer also noted that Android Pie custom ROMs could experience issues because of hard-coded interface values.
This is an important reminder that theme compatibility is not guaranteed.
4. Flux Substratum Theme
Flux is a Substratum-based theme that offers a material-inspired visual design.
Its published compatibility information includes several Android versions, including Android 9.
The theme offers different visual styles and application overlays.

How to Change Themes on Android Pie
The steps for changing themes depend on your smartphone manufacturer.
Samsung, Xiaomi, OnePlus, Motorola, and other brands may provide different customization settings.
Follow these general steps.
Step 1: Check Your Android Version
First, confirm that your smartphone runs Android 9.
- Open Settings.
- Find About Phone.
- Select Software Information if available.
- Check the Android Version.
- Confirm whether it displays Android 9.
The names of these settings can differ between manufacturers.
Step 2: Check Built-In Theme Options
Some Android manufacturers provide their own theme stores or customization applications.
Open your phone’s Settings and look for options such as:
- Themes
- Wallpapers
- Display
- Home Screen
- Style
- Personalization
If your smartphone includes a theme store, explore the available designs.
Read the theme description before applying it.
Step 3: Select a Wallpaper
A wallpaper is one of the easiest ways to change the appearance of your phone.
You can choose from:
- Nature photography
- Abstract designs
- Minimal backgrounds
- Gradient colors
- Dark wallpapers
- Geometric patterns
Choose an image with enough empty space if you want your home screen icons to remain easy to read.
Step 4: Customize Application Icons
If your phone supports third-party icon packs, you can change the appearance of application shortcuts.
Some launchers provide built-in icon pack support.
Check whether the icon pack works with your selected launcher.
Step 5: Arrange Your Home Screen
Move frequently used applications to the home screen.
Create folders for similar applications, remove unnecessary shortcuts, and adjust the icon layout.
A simple arrangement can make the phone easier to use.
Step 6: Add Widgets
Widgets display useful information directly on the home screen.
Depending on the launcher and widget application, you may be able to add:
- Clock widgets
- Weather widgets
- Calendar widgets
- Battery information
- Music controls
- Notes
- Search bars
Avoid adding too many widgets because they can make the interface crowded.
Step 7: Apply and Review Your Changes
After making your changes, return to the home screen.
Check the readability of icons, widget placement, and wallpaper contrast.
If something does not look right, adjust the settings or choose another design.
How to Install Android Pie Themes Using Substratum
Substratum is an advanced customization method.
It should only be used when the theme and theme engine explicitly support your Android version and device configuration.
The general process is as follows:
Step 1: Check Device Compatibility
Before downloading anything, confirm:
- Your exact Android version
- Your phone manufacturer
- Whether your ROM supports Substratum
- Whether root access is required
- Whether the selected theme supports your device
Never assume that a theme supporting Android 9 will work on every Android 9 smartphone.
Step 2: Install the Required Theme Engine
Use the official application listing or a trusted developer source.
Avoid unknown websites offering modified application packages.
Check the application’s permissions and installation requirements.
Step 3: Select a Compatible Theme
Choose a theme that specifically lists support for your Android version and software configuration.
Read its installation guide.
Step 4: Review Theme Overlays
Some Substratum themes provide separate overlays for different applications and system components.
Select only the overlays that are documented as compatible with your device.
Step 5: Build and Apply
Follow the developer’s instructions to build and apply the selected overlays.
The exact process can vary by Android version and installation method.
Step 6: Restart and Check the Interface
Some configurations require a restart.
After applying the theme, check the notification panel, system interface, and supported applications.
If you notice errors, follow the developer’s instructions to disable the problematic overlays.
Important: Substratum customization can require technical knowledge. Do not experiment with system overlays if you do not understand how to restore the original interface.
Can You Install Android Pie Themes Without Root?
Yes, but the available options are more limited.
You can personalize many parts of an Android smartphone without root access.
For example, you may be able to:
- Change the wallpaper
- Install a compatible launcher
- Use supported icon packs
- Add home screen widgets
- Change the home screen layout
- Customize supported manufacturer settings
These changes usually affect the home screen rather than every part of the operating system.
System-wide customization is different.
Some advanced theme engines need root access or a compatible custom ROM to modify system interface elements.
The exact requirements depend on the tool.
If you are a beginner, start with wallpaper, widgets, launcher settings, and icon packs instead of modifying system files.
Best Android Pie Customization Ideas
You do not always need a complete theme package to create a good-looking smartphone interface.
Combining a few simple customization options can produce an attractive result.
Here are some ideas.
1. Create a Clean Pixel-Style Home Screen
Choose a simple wallpaper and a compatible launcher.
Keep only frequently used applications on the home screen.
Use a clean icon pack and add a clock or calendar widget.
This setup is suitable for people who like a simple interface.
2. Build a Dark Home Screen
Choose a black or dark-grey wallpaper.
Use compatible light-colored icons and avoid widgets with poor text contrast.
If your phone supports a dark system interface, enable it through the manufacturer’s settings.
3. Try a Nature-Inspired Theme
Nature wallpapers can make a smartphone look attractive without requiring advanced customization.
Try images of:
- Mountains
- Forests
- Beaches
- Flowers
- Lakes
- Night skies
Choose simple icons that do not clash with the wallpaper.
4. Use a Productivity-Focused Layout
Arrange your home screen around your daily activities.
For example, place your calendar, notes, email, and task applications in easy-to-access locations.
Use widgets to display information without opening every application.
5. Choose a Minimalist Design
Use one main color, a plain wallpaper, and a small number of home screen icons.
Remove unnecessary widgets and organize the application drawer.
This can make navigation easier.
Android Pie Themes for Different Smartphone Brands
Theme compatibility depends heavily on the manufacturer’s software.
Here are some important considerations.
Samsung Smartphones
Samsung devices running Android Pie may use Samsung’s own interface and theme system.
Galaxy Themes availability depends on the particular device and software configuration.
Some Substratum themes have separate Samsung compatibility requirements.
Do not install an AOSP-only theme on a Samsung device without checking its documentation.
Xiaomi Smartphones
Xiaomi phones running Android Pie may use MIUI.
MIUI has its own customization system, which can provide themes, wallpapers, icons, and other visual options.
The available features depend on the device and MIUI version.
OnePlus Smartphones
OnePlus devices running OxygenOS based on Android Pie may support certain customization options.
Some historical Substratum themes specifically listed OxygenOS Pie compatibility.
However, a theme intended for one OxygenOS release may not work correctly on another.
Motorola Smartphones
Motorola smartphones often provide an Android experience with manufacturer-specific additions.
The customization options can vary by model.
Users can explore supported wallpaper, display, and launcher settings.
Google Pixel Smartphones
Pixel devices provide Google’s Android interface.
Users can personalize their supported wallpapers, home screen elements, and display settings.
Third-party launchers can provide further home screen customization.
Android Pie Themes vs Launchers: What Is the Difference?
Many users confuse themes with launchers.
They are related, but they do not perform exactly the same job.
A launcher controls the home screen and application drawer.
A theme may change visual elements across supported parts of the interface.
| Feature | Launcher | Theme |
|---|---|---|
| Home screen layout | Yes | Sometimes |
| Application drawer | Yes | Sometimes |
| Icon appearance | Supported icon packs | Supported themes |
| Wallpaper | Usually | Often |
| System interface | Usually limited | Depends on support |
| Notification panel | Usually no | Some system themes |
| Root requirement | Usually no | Depends on theme engine |
If you only want a different home screen, a launcher is usually the easier choice.
If you want to change deeper system elements, you must check whether your device supports a compatible theme engine.
Benefits of Using Android Pie Themes
Themes can improve the visual appearance and organization of a smartphone.
Here are some potential benefits.
1. Better Personalization
Users can select designs that match their preferences.
A smartphone does not have to look exactly like every other device.
2. Improved Home Screen Organization
Launchers and customization tools can help users arrange applications and widgets.
This can make frequently used features easier to access.
3. A Fresh Look for Older Devices
Changing wallpapers, icons, and layouts can make an older phone feel visually different.
It can be a useful way to personalize a device without buying new hardware.
4. Different Visual Styles
Users can experiment with dark, light, minimalist, colorful, and material-inspired designs.
5. More Control Over Appearance
Compatible launchers and customization tools provide additional control over the home screen.
Users can change icon sizes, widget placement, grids, and other elements.
Disadvantages of Android Pie Themes
Themes also have some limitations.
1. Compatibility Problems
Not every theme supports every Android Pie device.
A theme designed for an AOSP custom ROM may fail on modified manufacturer software.
2. Limited System Customization
Some launchers only change the home screen.
They cannot automatically change the entire operating system.
3. Performance Considerations
Some heavily customized launchers and live wallpapers may use additional memory, processing resources, or battery power.
Older smartphones may perform better with simpler customization options.
4. Security Risks
Downloading themes from unknown sources can expose your smartphone to unwanted applications or malicious software.
Always use trusted sources and review permissions.
5. Older Applications May No Longer Receive Updates
Some Android Pie theme applications were developed several years ago.
Their developers may have stopped supporting them.
This can make installation and troubleshooting more difficult.
How to Choose the Best Theme for Android Pie
Choosing a theme should involve more than looking at screenshots.
You should consider compatibility, usability, security, and performance.
Check Android Version Requirements
Read the minimum Android version in the application listing.
Confirm that the theme supports Android 9 rather than assuming compatibility from its name.
Read Recent Reviews
Look for reviews that mention your device model and software version.
Old positive reviews do not guarantee that an application is still maintained.
Check Developer Information
Prefer applications with clear developer information, installation instructions, and support details.
Review Permissions
A wallpaper or icon application generally should not need access to unrelated personal information.
Review permissions before granting them.
Consider Performance
If you use an older smartphone, select lightweight customization options.
Avoid unnecessarily complicated widgets and animated backgrounds.
Check Whether Root Is Required
This is especially important for Substratum themes.
Read all requirements before purchasing or installing a theme.
Android Pie Dark Theme: What You Should Know
Dark themes are among the most frequently discussed Android customization options.
Android Pie introduced a device-dependent dark appearance setting.
On some Android Pie devices, users could select a dark device theme through display settings.
However, this did not automatically make every application dark.
Individual applications needed to support the appropriate appearance settings.
Some manufacturers also provided their own dark interface options.
Users should therefore distinguish between three things:
- A dark wallpaper.
- A dark home screen or launcher.
- A system-wide dark interface.
These are not the same.
Changing a wallpaper to black does not change the background of every application.
Similarly, installing a dark launcher does not necessarily change the notification panel or system settings.
How to Fix Common Android Pie Theme Problems
Sometimes a theme may not work as expected.
Here are a few common problems and practical solutions.
Problem 1: Theme Does Not Apply
Possible reason: The theme does not support your device or Android version.
Solution:
- Check the Android version.
- Review the theme’s compatibility list.
- Confirm that the required theme engine is installed.
- Follow the developer’s installation instructions.
Problem 2: Icons Do Not Change
Possible reason: Your launcher may not support the selected icon pack.
Solution:
- Open the launcher’s settings.
- Find the icon customization option.
- Select the compatible icon pack.
- Restart the launcher if necessary.
Problem 3: Dark Theme Does Not Work in Every App
Possible reason: Individual applications may not support the selected dark interface.
Solution:
- Check the application’s appearance settings.
- Update the application if a compatible update exists.
- Use its built-in dark mode when available.
Problem 4: Smartphone Becomes Slow
Possible reason: Live wallpapers, widgets, or a resource-intensive launcher may affect performance.
Solution:
- Remove unnecessary widgets.
- Disable animated wallpapers.
- Try a simpler launcher.
- Restart the smartphone.
- Remove applications that you no longer use.
Problem 5: System Interface Looks Incorrect
Possible reason: A system overlay may be incompatible.
Solution:
- Follow the theme developer’s recovery instructions.
- Disable the incompatible overlay.
- Restore the original settings if necessary.
- Avoid applying additional system modifications until the problem is resolved.
Are Android Pie Themes Safe?
Android themes can be safe when downloaded from trusted sources and installed according to their requirements.
However, not every customization application is trustworthy.
Before installing an application, consider the following safety practices:
- Download applications from Google Play when available.
- Check the developer’s identity.
- Read application permissions.
- Review recent user feedback.
- Avoid unknown modified APK files.
- Do not grant unnecessary root permissions.
- Back up important data before advanced system customization.
- Avoid tools that promise unrealistic performance improvements.
Be particularly careful with applications that request accessibility access, device administrator privileges, or root access without explaining why they need them.
A theme should improve the appearance of your smartphone, not create unnecessary security risks.
Can Android Pie Themes Work on Newer Android Versions?
Some themes originally designed for Android Pie may work on newer Android versions, but compatibility is not guaranteed.
Android system interfaces, security restrictions, application resources, and manufacturer software change over time.
For example, a theme built around Android 9 system resources may not work correctly on Android 12 or Android 15.
Some theme developers provide separate versions for different operating systems.
Others stop maintaining older projects.
Always check the supported Android versions before installation.
The same rule applies in reverse: a modern launcher may support older Android devices, but that does not mean every feature will work on Android Pie.
