Topics in Xiaomi Redmi smartphones: a complete guide to personalizing the interface

Xiaomi Redmi smartphones have long been popular not only for their value for money, but also for their flexible customization capabilities. One of the key features of MIUI is the theme system, a tool that allows you to radically change the appearance of your device in just a few clicks. From changing icons and fonts to completely transforming animations and sounds, themes turn the standard interface into a unique style that reflects your personality.

But many users still don't use it to its fullest, some don't know where to look for quality themes, some are afraid of "breaking" the phone with the wrong settings, and some simply don't realize that in addition to the standard options from the Xiaomi Themes store, there are alternative sources with thousands of free designs. In this article, we'll break down everything from the basic principles of how the theme works to hidden features that are not even written in the official instructions.

What are Xiaomi Redmi themes and how do they work?

MIUI themes are not just a collection of wallpaper and icons, but full-fledged skins for the operating system.

  • 🎨 Appearance of application icons and system utilities
  • πŸ“± Design of notification panels and quick settings
  • πŸ”€ Fonts (including system and for individual applications)
  • 🎡 Sound effects (calls, notifications, keyboard signals)
  • πŸ–ΌοΈ Wallpaper for desktop and lock screen
  • πŸ”„ Animations of transitions between screens

It is important to understand that the themes in Xiaomi are divided into two types:

  1. Local themes are installed through the standard Theme Store and stored in the device’s memory, fully integrated into the system and updated automatically.
  2. MTZ-themes – files with the.mtz extension that are downloaded from third-party sources (for example, Mi Themes or Xiaomi Themes Store) must be installed manually through the file manager.

The application of the theme does not require superuser rights (root) and does not affect the performance of the smartphone. All changes are reversible: at any time you can return the standard interface or switch to another topic. However, there are nuances: some elements (for example, icons of system applications) may not change in custom themes due to the limitations of MIUI.

Top.-5 Mistakes in working with topics and how to avoid them

Even experienced users sometimes encounter problems with the application of themes, and here are the most common mistakes and solutions:

  1. Subject not applicable: Reason: incompatible with MIUI version or corrupted file Solution: check firmware version in Settings β†’ About Phone β†’ MIUI version and compare to the theme requirements. If it doesn't match, look for an alternative.
  2. Icons are displayed in low resolution: Reason: the original icon files have a resolution below 192Γ—192 pixels. Solution: replace the icons in the icon folder with high-quality ones (you can download on Flaticon).
  3. After applying the theme, the widgets disappeared: Reason: the theme overwrote the widget system files. Solution: return the standard theme, then re-add the widgets to the desktop.
  4. Theme applies partially (e.g. wallpaper only): Reason: no rights to change system elements. Solution: go to Settings β†’ Permissions β†’ Special Access β†’ Change system settings and enable access for the Theme app.
  5. The phone overheats after the theme changes: Reason: Some animations in the topic are too resource-intensive. Solution: turn off animations in Settings β†’ Additional β†’ System Animation or choose a lighter theme.

All of these themes are available in the official Theme Store (free or for Mi Credits). For Redmi Note 12 and later, we recommend paying attention to themes marked "Adaptive" - they automatically adjust to the color range of wallpaper.

FAQ: Frequent questions about topics in Xiaomi Redmi

Can I install a theme from one Xiaomi to another?
Yes, but with reservations..mtz files are universal for all devices on MIUI, however: On older smartphones (e.g. Redmi 5), new themes may not work properly due to an outdated version of the firmware. Some elements (e.g. animations) require a specific version of MIUI (indicated in the theme description). If the target device has a different screen allowed, the icons may be displayed stretched.
Why are some themes paid when MIUI has free themes?
Paid themes usually offer: exclusive design from professional studios; additional elements (such as custom sounds or animations); regular updates and support from developers. However, most paid themes can be found for free on forums (such as 4PDA), but beware - such files are often modified and may contain ads.
How to make a backup copy of the current theme?
You can save your current theme by downloading the MIUI Theme Backup app from Google Play. Open it and click Backup Current Theme. The backup file will be saved in the MIUI/backup/theme/ folder. Use the Restore option in the same app to restore it.
Can you use themes on Xiaomi with custom firmware (like LineageOS)?
No,.mtz themes only work on official MIUI. For custom firmware (like LineageOS or Pixel Experience), use: Substratum themes (root rights required); Nova Launcher (Apex Launcher); Magisk modules to change system elements.
Why did my topic drop after the MIUI update?
With major MIUI updates (e.g., version 13 to version 14), the system file structure changes and old themes become incompatible. To avoid this: Before updating, back up the theme (see question above). After updating, check for a new version of the theme in the store. If there is no theme, contact the developer (contacts are usually listed in the description).
