Xiaomi smartphone users often face the desire to change the standard appearance of the MIUI shell or HyperOS. The standard interface, although functional, can seem boring or overloaded with unnecessary elements. Changing the visual style is the easiest way to personalize the device, making it unique and convenient for you.
The process of installing graphics on Xiaomi is very different from other Android smartphones due to its powerful theme system. You don’t need root rights or complex manipulation of system files to change the icons, fonts, wallpaper and even the sounds of the system. All the necessary tools are built into the shell itself.
In this article, we will discuss in detail how to put a regular theme on Xiaomi using official methods and proven third-party solutions, you will learn where to look for quality designs, how to activate them correctly and what to do if the desired design is not applied correctly.
Official Theme Store: Search and Installation
The easiest and safest way to change the interface is to use the built-in Themes app, which is a pre-installed system component that has access to all the necessary permissions to modify the interface, and it's a collection of thousands of design options created by Xiaomi and independent designers alike.
To get started, open the Themes app on your desktop. At the bottom of the screen, you'll see a navigation bar where you select the Profile tab or go straight to Categories. In the search bar, you can type in keywords like "Minimal," "iOS style," or "Cyberpunk" to find the desired style.
Once you have selected your favorite option, click Download. The download process will take a few seconds depending on the file size and Internet speed. Once you download the button, change to Apply. When you click on it, you start the installation process, which can take up to a minute.
Important: Some themes are marked with a DIY or Mix icon, which means you can choose individual design elements (like just icons or just lock screen) and combine them with others.
- 🎨 Thousands of free options from the community.
- ⚡ Quick installation without the need to reboot the smartphone.
- 🔄 Ability to automatically update themes when new versions are released.
⚠️ Note: If widgets are missing after applying the theme or the font size has changed in the settings, try clearing the theme app cache through the Settings menu» → «Annexes» → «All applications».
The official store is regularly updated, and many themes have user ratings. Pay attention to the number of downloads and reviews to avoid bugs or poor graphics. Sometimes developers add ads to themes that can be turned off in the settings of the theme application itself.
Importing third-party themes and working with files.mtz
Often users want to install a theme that is not in the regional store, or use a file downloaded from the Internet. Theme files for Xiaomi have the extension.mtz. To install them with standard means, you may need to change the region or use special import methods.
If you downloaded a theme file from a trusted source, place it in the root of internal memory or in the MIUI/theme folder. Then open the Themes app, go to the profile (human icon) and click on the folder icon or the Import button. The system will scan the memory and suggest installing the files found.
In some cases, especially on global firmware, third-party themes may be blocked. Then you need to turn on developer mode. Go to Settings → About phone and quickly press 7 times on the MIUI version. Then in advanced settings, find the item “Debug over USB” and activate it.
Why aren’t the topics installed on the global firmware?
There is a method of installation through a computer using ADB-For most users, it is easy to change the region in the Date and Time settings to India or Nepal, where restrictions are often removed by default.
- 📂 Theme file format is strictly.mtz.
- 🌍 Changing the region can unlock the installation of any themes.
- 🔒 Root rights for importing themes are not usually required.
Once the theme is successfully imported, it will appear in the My Themes section, from there it can be activated at any time, and remember that third-party themes may contain errors, so always check the source of the download.
Configuration of components: mixes and constructor
Xiaomi allows you to not only put ready-made themes, but also create your own combinations. The Mix themes feature (or constructor) allows you to choose the best elements from different sources. You can leave system fonts from one theme and take icons from another.
To use this feature, go to the Themes → Profile → Component Customization (or Mix Themes) app. Here you will see a list of all available elements: lock screen, desktop, control panel, sounds, system icons.
Click on any element, such as "Block Screen" and you'll see a gallery of all available options, including standard and downloaded ones. If you choose the one you like, click "Apply" so you can assemble the perfect interface that will meet all your requirements.
💡
Use the Mix Theme feature to keep your navigation familiar, but update the visual style of the icons, which reduces the risk of getting used to the new interface.
Special attention should be paid to the lock screen. In the theme store there are options with widgets, animations and complex passwords. When choosing a new lock screen, the system will warn you that the old widgets may stop working.
- 🧩 Flexible configuration of each interface element separately.
- 💾 Saving created mixes in profile.
- 🎨 The ability to use elements of paid themes for free (if they are already downloaded).
Theme builder is a powerful tool for those who like order, and you can make the interface as minimal as possible by removing unnecessary watches or weather widgets, if the theme you choose allows.
Comparison of thematic sources
Understanding the differences between the sources of the theme will help you choose the right option. The official store offers stability, but may have limitations. Third-party resources give freedom, but require caution.
Below is a table that will help you navigate the installation methods and their features.
| Source | Security | Diversity | Complexity of installation |
|---|---|---|---|
| Official store | Tall. | Medium | Low. |
| Third-party sites (.mtz) | Medium | Tall. | Medium |
| Topics Editor (PC) | Tall. | Maximum | Tall. |
| Modified themes | Low. | Tall. | Tall. |
The official store ensures that the theme is free of malicious code and optimized for your version of Android. Third-party.mtz files can be modified by enthusiasts to add features that are not in the original, but it is always a risk.
Using a theme editor on a PC requires connecting your smartphone over USB and installing special software, which is a way for advanced users who want to create a theme from scratch or deeply edit an existing one.
Choose a source based on your skills and security requirements, and there are more than enough official resources for everyday use.
Solution and resetting of settings
Sometimes, after you install a theme, you can have problems: buttons don't work, sound goes missing, or the interface becomes unstable, and in these cases, you don't have to panic. Most problems are solved by simply going back to the standard design.
To reset the theme, open the Themes app, go to Profile → My Themes. Find a theme called Classic or Defult (usually first on the list) and click Apply. This will return all interface settings to factory status.
If the problem is not solved, try to clear the Topic app data. Go to Settings → Apps → All apps, find Topics, select Storage, and click Clear. After that, the phone may need to restart.
⚠️ Warning: Before installing heavy animated themes, make sure the device has enough free RAM. On budget models, this can cause the system to slow down.
Themes created for older versions of MIUI 11 or 12 may not show correctly on HyperOS or MIUI 14. Always check the update date for the theme and user comments.
- 🔄 Resetting to a Classic Theme Solves 90% of Problems.
- 🗑️ Cleaning the cache helps with application errors.
- 📉 Heavy topics can reduce battery autonomy.
Regular updates to system software also help avoid conflicts with new versions of themes. Xiaomi often makes changes to the interface structure that older themes may not support.
Optimization and selection tips
Choosing a theme is not just a matter of aesthetics, but also ergonomics. Too bright or contrasting icons can quickly tire your eyes, especially when using a smartphone at night, and it is recommended to choose themes that support a dark theme or use separate night profiles.
Pay attention to the readability of widgets. A beautiful but unreadable theme loses its meaning. A good theme should blend harmoniously with Google widgets and system utilities without overlapping important information.
💡
The optimal theme is a balance between visual appeal and functionality. Don't sacrifice convenience for beauty.
If you use your smartphone with one hand often, choose themes where the main controls are shifted down the screen, which will make navigation easier on devices with large diagonals.
Remember to check the permissions that the theme requests when installing. While this is rare, some topics may request access to contacts or geolocation for no apparent reason.
Experiment with different styles, but always leave the possibility of a quick rollback. Save screenshots of successful combinations, so as not to look for them again in the future.
