Changing the visual interface is the first thing a new Xiaomi, Redmi or POCO smartphone owner does. The standard shell, whether itβs MIUI or the latest HyperOS, offers many possibilities, but itβs the themes that allow you to completely change the experience of the device. You can turn a strict working tool into a bright gaming gadget or a minimalist device in just a few touches of the screen.
The process of replacing the design in the ecosystem of the Chinese manufacturer is as simplified and built deep into the system. However, many users are limited to only basic choices from the directory, unaware of the existence of third-party repositories and the possibility of manual installation of files. In this article, we will discuss all the ways, from standard to advanced, so that you can unlock the potential of your smartphone.
Itβs important to understand that the change in appearance affects more than just app icons, changing the design of notification curtains, lock menus, system fonts and even charging animations, personalization on devices of this brand is at the forefront of all Android manufacturers, providing tools that other brands usually hide or require root rights.
Standard way to change design through the Topics app
The easiest and safest method is to use a regular app that is pre-installed on each device, called Themes (or Themes), and has a signature brush or palette icon, and that's where the official directory is located, which moderation ensures that no malicious code is present in the downloaded items.
To get started, you need to open the application and log in to your Mi Account. Without a profile login, access to download most free and paid designs will be limited. Once authorized, the system will suggest choosing a region; for maximum content selection, it is often recommended to install the "India" or "Singapore" region, since there are the most extensive directories.
- π¨ Open the Themes app on the home screen or in the Tools folderΒ».
- π Use the search bar at the top to search for keywords, for example, Β«AMOLEDΒ», Β«Minimal or the names of specific games.
- π₯ Click the Download button (down arrow) next to your favorite option.
- β After downloading, click βApplyβ to activate the new style.
β οΈ Note: When you change the theme through the official store, the old Music widget settings or the lock screen clock may reset. Take screenshots of the current configuration in advance if you want to keep the exact location of the elements.
Inside the directory, there is a convenient filter system that allows you to sort content by rating, novelty or popularity. Also worth paying attention to the For You section, where artificial intelligence algorithms offer options based on your browsing history. If you liked a particular icon or wallpaper but (set) does not fit, in many cases only individual elements can be used, although the functionality of separate installation in new versions of the shells is often hidden.
Manual installation of themes from files.mtz
The official store isn't the only source of inspiration. The community of enthusiasts creates thousands of unique designs that are distributed as.mtz files. These files can be found on specialized forums like 4PDA or XDA Developers. The manual install gives access to exclusive content that is not in the official directory.
To install the downloaded file, you first need to download it to the smartphone memory. After downloading, go to the Profile menu (the person icon in the Themes app) and select Subjects. Here click on the folder icon in the upper corner to open the local storage. The system will automatically find all compatible files in the device memory.
The process of using third-party files is almost the same as the standard one, but it requires attention to the shell version. The theme created for MIUI 12 may not display correctly on HyperOS due to changes in the structure of system files.
π‘
If the file.mtz is not applied and a compatibility error is issued, try renaming the file extension to.zip, unpacking it, finding the description.conf file and changing the MIUI version to the current one, then packing it back.
Data security is a priority, so avoid sites with intrusive advertising and questionable reputations. Theme files may contain executable code, so download content only from trusted resources with an active community.
Use of third-party launchers and applications
Sometimes, the standard system is not enough, or the user wants to get a clean Android experience. In such cases, third-party launchers come to the rescue. These are applications that completely replace the desktop, app menus and often widgets. The most popular solutions are Nova Launcher, Lawnchair and Microsoft Launcher.
Installing a third-party launcher requires additional permissions. Once downloaded from Google Play, you need to launch the application and allow it to work as the main interface. Xiaomi's system can warn you of potential risks several times, but for proven launchers it is safe.
The main advantage of third-party solutions is the flexibility of settings. You can resize the icon grid, add gestures, change the animation of opening applications and even hide the "bang" of the screen in a software way. However, it is worth remembering that third-party launchers can consume more battery resources than an optimized system interface.
| The name of the launcher | Difficulty setting up | Impact on the battery | Widget support |
|---|---|---|---|
| Nova Launcher | Tall. | Low. | Complete. |
| Microsoft Launcher | Medium | Average. | Integration with PC |
| Lawnchair | Low. | Low. | Basic |
| Smart Launcher | Automatic. | Average. | Adaptive |
β οΈ Warning: After installing a third-party launcher, the Home button (swipe bottom or center button) may be delayed or return you to the old interface. To avoid this, force the new application to be selected by default in the Home Screen settings.
Creating your own theme from scratch
For those who have design skills and want to create a unique interface, there is an official tool called Theme Editor, which is a PC software that lets you disassemble existing themes and create new ones from scratch. The process takes time and understanding the file structure, but the result is worth it.
The first step is to download the editor from the official Xiaomi developer portal. After installation, select the basic theme (usually a standard MIUI 12 or 14) and start modifying the elements. You can redraw the icons, change the colors of the system windows, add your wallpaper for the lock screen and customize the fonts.
Creating a custom theme is not just about drawing pictures; you need to correctly prescribe configuration files so that the buttons respond to clicks and text is read against any background. Errors in the code can cause the phone to go into a cyclic bootloop, so always test the theme on a virtual machine or a second device.
- π₯οΈ Download and install. MIUI Theme Editor on the computer.
- π Import a basic theme or create a new folder structure.
- βοΈ Edit the graphic elements (PNG) and XML-configuration.
- π€ Collect the project and export the finished file.mtz.
Where to find official design guidelines?
Set up fonts and element sizes
Changing theme often goes hand in hand with typography, and the theme store has a separate font section where you can find both classic and decorative fonts, and installing a new font changes the way text is displayed throughout the system: in messages, settings and browser.
Beyond letter style, size is critical. In today's smartphones with a diagonal of more than 6 inches, the standard font may seem small. Go to Settings β Screen β Text and size to adjust the scale. Here you can turn on Read Mode, which adds a yellow filter and changes the texture of the background, mimicking paper.
Also, remember the size of the icons. In some themes, icons can be too large or small relative to the widgets. In Settings β Home screen, you can select the grid size (e.g., 4x6 or 5x5), which automatically scales all interface elements.
βοΈ Checklist of ideal personalization
For people with visual impairment, the system has a "magnified text" mode and high-contrast themes, which make the interface less beautiful from a design point of view, but much more convenient for everyday use, and accessibility is an important aspect that HyperOS developers are actively developing.
Solution: Mistakes and conflicts
Users often experience problems in their experience with the look, one of the most common is the black screen after applying the theme, which happens when the theme is incompatible with screen resolution or the Android version. If it does, press the power and volume button (or just power, depending on the model) to trigger the recovery menu, and try running Safe Mode.
Another common problem is desynchronizing icons. Once the system is updated, some icons can become white squares or Android logos. This is solved by clearing the cache of the Themes app. Go to Settings β Apps β All Apps β Topics β Clear the data.
Users also complain about the slow operation of the interface after installing βheavyβ themes with live animations. Live wallpaper and dynamic clocks on the lock screen consume battery power and load the processor. If you notice lags, go back to static design.
β οΈ Warning: Never download topics that require a superuser (Root) right to install unless you are sure of the source.Modifying system files without a backup can lead to loss of warranty and unstable device operation.

The most common reason for a theme change crashes is MIUI/HyperOS conflict. Always check which version of the shell theme is created for, especially if you are using Global or China ROM.
