The standard interface Android may seem too strict or boring, especially if you have been using the phone for several months. Fortunately, the ecosystem of this operating system allows you to change not only the wallpaper, but also color schemes, application icons, and the overall menu structure.
The process of changing the theme can vary dramatically depending on the manufacturer of your gadget. Owners of devices Samsung, Xiaomi or Huawei have built-in tools for deep customization, while users of “pure” Android will have to resort to installing third-party launchers. Understanding these differences will help you avoid unnecessary actions and quickly achieve the desired result.
In this article we will analyze all the available methods for changing the appearance of the system: from standard settings to advanced utilities. You will learn where to look for safe themes, how to install custom icons, and what pitfalls can be encountered on the way to the ideal interface.
Built-in options for changing themes on different shells
Smartphone manufacturers often create their own add-ons on top of the base system Android, adding unique personalization features to them. If you have a device from a major brand, you likely won't have to download anything extra. For example, the shell from Samsung or from Xiaomi have powerful built-in theme stores. To access these functions, you usually just need to go to the settings menu and find the appropriate section. In some cases, manufacturers move theme management into a separate application that is preinstalled on the device. This allows you to change not only colors, but also fonts, notification sounds, and even screen unlock animation. One UI from Samsung or MIUI from Xiaomi have powerful built-in theme stores.

However, it is worth considering that free themes in official stores often contain advertising or offer only basic changes. Premium options may require payment or a subscription.

Using third-party launchers for full functionality customization
If the built-in tools of your smartphone do not satisfy your aesthetic needs, the best solution is to install a third-party launcher. The launcher is an application that completely replaces the desktop and application menu, providing new gestures, animations and customization options. Popular options include Nova Launcher, Microsoft Launcher and Lawnchair.
After installing the launcher, the system will prompt you to select it as the default application for the home screen. This is a key point: without confirming this action, the new interface will not be activated. Most modern launchers support the installation of icon packs, which allows you to visually change absolutely all applications on the device, even those that are not included in the theme.
It is important to note that launchers do not change system windows, such as settings, notification shade or lock screen (with rare exceptions). They operate exclusively within the user's workspace. However, the combination of a high-quality launcher and a set of icons gives an effect that is almost indistinguishable from a complete change of system theme.
Before installing a new launcher, take screenshots of the location of your widgets and folders. After changing the interface, you will have to set up your desktop again, and old photos will help you quickly restore the familiar structure.
Step-by-step guide for installing themes and icons
The process of installing visual elements may seem confusing for a beginner, but in fact it consists of several logical steps. You must first prepare the device, then select a content source, and finally apply the changes. Strict adherence to the algorithm will allow you to avoid errors and conflicts in the operation of the interface.
Below is a universal checklist that will help you prepare for the procedure of changing the theme. It is relevant both for using built-in stores and for working with third-party applications from Google Play.
☑️ Preparing to change the theme
After preparation, proceed to installation. If you're using a third-party launcher, open its settings and find the Appearance or Look & Feel section. There you can apply the downloaded icon pack. In the case of built-in themes, the process usually comes down to clicking the “Apply” button in the selected design card.
Sometimes, after applying a theme, the icons of some applications may remain standard. This happens because the theme developer did not draw an icon for a specific application. In such cases, you can use the “masking” function in the launcher settings or manually select an icon from another set.
Customizing colors and fonts through Material You
Starting with version Android 12, Google has implemented a design system Material Youthat allows the system to automatically adjust interface colors match the colors of your wallpaper. This feature, known as Color Palette, changes the shades of buttons, switches and widgets throughout the system, creating a harmonious visual style.
To activate this feature, go to Settings → Wallpaper and style. There you will see the “Color Palette” section. By turning it on, you can choose from several suggested color combinations generated based on the current screen background. This is the easiest way to refresh your appearance without installing heavy themes.
In addition to colors, Material You allows you to change widget sizes and fonts. Changing the font size affects not only the system, but also most supporting applications, making the text more readable or compact depending on your preferences.
| Function | Where to find | Impact on the system |
|---|---|---|
| Color palette | Settings → Wallpaper and style | Changes the colors of buttons, menus and widgets |
| Icon style | Settings → Wallpaper and style → Icons | Applies shape (circle, square) to all icons |
| Font size | Settings → Screen → Font size | Changes text in the system and applications |
| Display size | Settings → Screen → Display size | Scales all interface elements |
The Material You function works most correctly on smartphones with “pure” Android or the Pixel Experience shell. On custom firmware from other brands, it may be limited or absent.
Advanced customization using Substratum and theming
For users who want to change absolutely every pixel on the screen, including the notification panel, settings menu and keyboard, there are more powerful tools. One of the most famous solutions in the past was the application Substratum, however, with the release of new versions Android its functionality was significantly limited without obtaining superuser rights (Root).
Without root access, modern theming methods rely on the use of overlays and special developer modes. Some manufacturers, for example Xiaomi s their theme Dark Mode for third-party applications, provide partial access to system colors through the engineering menu. Activation of such modes requires entering special commands through the app ADB or terminal.
If you decide to get Root access for complete freedom of action, remember that this will void the warranty and can lead to damage to the device if done incorrectly. Firmware with theme support, such as LineageOS with addon Substratum, offer a safe environment for experiments, but require a complete flashing of the smartphone.
⚠️ Attention: Obtaining root access and modifying system files can lead to “bricking” the device. Also, banking applications and contactless payment services (Google Pay) can. stop working on rooted smartphones.
How to enable theming without Root on Xiaomi?
On some Xiaomi devices, you can activate advanced themes through the developer menu. To do this, enable the developer mode, find the “Enable MIUI optimization” item and disable it after rebooting some. system restrictions on the use of themes may be lifted, but stability of operation is not guaranteed.
Possible problems and solutions
In the process of changing the theme, you may encounter a number of technical problems. The most common of them is incorrect display of icons or launcher crashes. This often happens when there is a conflict between application versions or when using themes created for older versions. Android.
If your phone starts running slower after installing a theme, check whether the new interface is using too much RAM. Heavy launchers with lots of animations can load the processor, which is critical for budget smartphone models. In this case, you should return to the standard launcher or choose a lighter alternative.
Another common problem is resetting the settings after a reboot. This may occur if the theme application has been moved to the SD card or is limited to running in the background by a power saving feature. To avoid this, add the launcher and theme manager to the battery optimization exclusion list.
If the interface has become unstable and the phone constantly reboots, you need to boot into safe mode. Typically, this involves holding the power button and then long pressing the Restart option on the screen. In safe mode, all third-party themes are disabled, which will allow you to remove the problematic application.
