Change Theme MIUI: Step-by-Step Guide

To change the theme on a Xiaomi, Redmi, or POCO device running MIUI, open the built-in Themes app, pick a theme, and tap “Apply.” You can also mix and match individual components like wallpaper, icons, and fonts from different themes. This guide walks you through the full process, including how to apply a theme, customize parts of one, and fix common issues.

What Is MIUI and How Do Themes Work?

MIUI is Xiaomi’s custom Android skin, used on Xiaomi, Redmi, and POCO smartphones. Unlike stock Android, MIUI has a centralized theme engine that changes not just the wallpaper but also system icons, fonts, boot animations, sounds, and even the lock screen style. Themes are packaged files (usually with a .mtz extension) that contain all these elements. The Themes app is preinstalled and serves as the store and manager for both free and paid themes.

How to Change the Whole Theme

  1. Open the Themes app on your device (it may be labeled “Themes” or “Theme Store”).
  2. Browse the featured themes or search for one using the search bar.
  3. Tap on a theme to see its preview and details.
  4. Tap the Apply button (sometimes labeled “Download” first if the theme isn’t downloaded yet).
  5. Wait for the download and application to finish. The theme will be applied immediately.

You can also apply a theme from the Settings app: go to Settings > Wallpaper & Theme (or “Personalization” depending on your MIUI version) and select a theme from there.

How to Change Only Part of a Theme (Mix and Match)

MIUI lets you combine elements from different themes. This is useful if you like the wallpaper from one theme but the icons from another. Here’s how:

  1. Open the Themes app.
  2. Tap on the Me tab (bottom right) and then My Themes.
  3. You’ll see a list of themes you’ve applied. Tap Customize (or “Edit”) on the current theme.
  4. You’ll see sections like Wallpaper, Icons, Fonts, Lock Screen, Sounds, and Boot Animation.
  5. Tap each section and select the element you want from any downloaded theme. For example, tap Icons and choose an icon pack from a different theme.
  6. Once you’ve made your selections, tap Apply.

How to Use Custom Themes (Not from the Store)

MIUI also allows you to apply themes downloaded from third-party sources, but there are restrictions. By default, MIUI only allows themes from the official store. To apply a custom .mtz file, you need to:

  1. Download the .mtz theme file to your phone.
  2. Move the file to the MIUI/theme folder on your internal storage (create the folder if it doesn’t exist).
  3. Open the Themes app, go to Me > My Themes.
  4. The custom theme should appear under “Local” or “My Themes.” Tap it and then tap Apply.

If the theme doesn’t appear, it may be because the file is corrupted or incompatible with your MIUI version. Some themes are for older MIUI versions and may not work on newer ones.

Common Problems and Fixes

  • Theme won’t apply: Restart your phone. If that doesn’t work, clear the Themes app’s cache (Settings > Apps > Themes > Storage > Clear Cache).
  • Theme reverts to default: This usually happens when the theme is not fully downloaded or the file is corrupted. Delete the theme and re-download it.
  • Can’t find the Themes app: On some devices (especially POCO), the app might be called “Themes” or “Theme Store.” If it’s missing, it may have been disabled. Go to Settings > Apps > Manage apps, search for “Themes,” and enable it.
  • Custom theme won’t show up: Make sure the file is in the correct folder (MIUI/theme) and that the file extension is .mtz. Also, check that you haven’t accidentally renamed the file.
  • Theme applied but icons don’t change: Some launchers (like the default MIUI launcher) may require you to apply the icon pack separately. Go to the Themes app, tap on your theme, and then tap “Customize” to apply the icons.

How to Choose a Theme

When choosing a theme, consider the following:

  • Style: MIUI themes range from minimalist to colorful, dark, or nature-inspired. Preview the theme to see how it looks on the lock screen, home screen, and in apps.
  • Dark mode support: Some themes are designed for dark mode and may look better with it enabled. Check if the theme supports dark mode in its description.
  • Performance: Heavily animated themes can slow down older devices. If your phone is low on RAM, prefer static or light themes.
  • Battery life: Live wallpapers and complex animations can drain your battery faster. For longer battery life, use static wallpapers.

Free vs. Paid Themes

The Themes app offers both free and paid themes. Free themes are abundant, but they may contain ads or require you to watch a video to unlock certain elements. Paid themes are usually ad-free and offer more polished designs. You can pay for themes using Mi Credits (Xiaomi’s virtual currency) or through your linked payment method. Some themes are also available for a limited time as free promotions.

Safety and Privacy

When downloading themes from third-party sources, be cautious. Malicious themes could contain code that tracks your activity or displays unwanted ads. Stick to the official Themes app whenever possible. If you must use a custom theme, download it from a trusted source and scan the file with a security app before applying it. Also, be aware that some themes require permissions (like access to your location or contacts) – only grant permissions that are necessary for the theme to function.

Frequently Asked Questions

How do I change the theme on MIUI without the Themes app?

You can’t fully change the theme without the Themes app, but you can manually change the wallpaper, icons, and font through Settings. Go to Settings > Wallpaper to change the wallpaper, and Settings > Display > Font style to change the font. For icons, you’ll need a third-party launcher like Nova Launcher, which lets you apply icon packs independently of MIUI.

Why does my MIUI theme keep reverting to default?

This often happens when the theme file is corrupted or not fully downloaded. Try re-downloading the theme from the store. If you’re using a custom theme, it may be incompatible with your MIUI version. Also, check if you have enough storage space – low storage can cause the system to revert to the default theme.

Can I use a theme from an older MIUI version?

In most cases, themes are forward-compatible, but not always. A theme designed for MIUI 10 may not work correctly on MIUI 12 or later. If the theme doesn’t apply properly, look for an updated version or contact the theme developer.

How do I create my own MIUI theme?

You can create your own theme using the MIUI Theme Editor (available for Windows). This tool lets you design wallpapers, icons, and other elements. Once you’ve created the theme, you can export it as an .mtz file and apply it to your phone as described above. Note that to publish your theme on the official store, you need to be a registered Xiaomi developer.

Does changing the theme affect battery life?

Yes, it can. Live wallpapers and animated elements consume more power. If you notice a significant battery drain after applying a theme, switch to a static wallpaper and disable animations in the theme settings.
