How to open a theme manager on your Xiaomi phone: all the ways (including hidden)

Why You Need a Xiaomi Theme Manager and Where to Find It

The theme manager on Xiaomi, Redmi and POCO smartphones is not just a wallpaper changer; it is a full-fledged interface customization center that allows you to change icons, fonts, animations of system applications and even sound schemes. Unlike standard Android themes, MIUI solutions are integrated deeper into the system, giving users unique personalization opportunities.

However, many device owners face a problem: the theme manager icon Suddenly disappears from the application menu, and search through the system does not yield results, this is due to the features of the MIUI shell, where some system utilities can be hidden depending on the firmware region or version of the software. In this article, we will discuss all the current ways to access the theme manager, from obvious to hidden.

It’s important to understand that theme manager functionality may vary depending on the MIUI version (12, 13, 14) and device model. For example, the flagships of the Xiaomi 13 series have exclusive themes with support for 120 Hz, which are not available on the budget Redmi Note.

Method 1: Standard launch through the application menu

The easiest way to do this is to find a theme manager icon on your desktop or app menu, which is called Themes in most cases, and has a signature brush or palette icon, and if you haven't changed the location of the icons, look for it on one of the main screens or in the Tools folder.

If the icon is missing, try:

• 🔍 Search the system: scroll down the desktop and type “Themes” or “Themes” in the search bar".
• 📁 Check the folder "Other applications" (on some firmware system utilities are grouped automatically).
• 🔄 Reboot the device – sometimes the icons “return” after the reboot.

⚠️ Note: On some global firmware (e.g., for the European market), the theme manager may be disabled by default due to licensing restrictions. → The phone. → Version. MIUI (more in detail in method 3).

Method 2: Quick access via screen settings

If the standard run didn’t work, try an alternative way through the display settings.This method works on all versions of MIUI, including MIUI 14 for Xiaomi 14 and POCO F5:

1. Open the settings (cog icon).
2. Go to the Screen section.
3. Select Wallpaper or Lock screen style.
4. At the bottom of the screen will appear the button "Themes" - click on it.

This path is especially useful for users who have their app icon disabled but still have access to system settings, and if the theme button is missing, it may indicate:

• 📱 Outdated version of the firmware (update through Settings) → Updating the system).
• 🌍 Regional restrictions (e.g. firmware for India or China).
• 🔧 Manual shutdown of system components through ADB third-party.

💡

If the Theme button is inactive, try changing the device region to India in the settings. This will often unlock additional MIUI features.

Method 3: Hidden launch using ## code

For power users, there is a hidden method of activating the theme manager through an engineering menu, which works even on devices with a remote app icon, but requires caution:

1. Open the phone (calling) application.
2. Enter the combination: ##6484###
3. Confirm the call (some models will require input) PIN-code).
4. In the menu that opens, select ThemeManager.

This code only works on MIUI firmware 12 and 13 for devices with Qualcomm processors (such as the Redmi Note 10 Pro or POCO X3). On models with MediaTek (such as Redmi 9A) and MIUI 14, it may not work.

⚠️ Warning: Do not change other options in the engineering menu unless you are sure of their purpose. Incorrect settings can lead to failures in the camera or network.

Method 4: Recovery through Resetting Theme Settings

If the theme manager is missing after a system update or reset, try to restore it by resetting the theme configuration. This method does not affect user data, but returns all system settings to factory:

1. Open Settings → Applications → Application Management.
2. Click on the three dots in the upper right corner and select "Show Systems".
3. Find the "Themes" list (com.miui.thememanager).
4. Select "Storage" → "Clear the data".
5. Reset the device.

After the reboot, the theme manager icon should appear in the app menu. If this does not happen, check:

• 📦 Updates for the Themes app in Google Play (for global firmware).
• 🔧 No restrictions through Settings → Special facilities → Simplified regime.
• 🛡️ Antivirus blocking (e.g., Avast or 360 Security can remove system components).

Method 5: Installation via APK (for advanced users)

If all previous methods have failed, you can try installing the Theme Manager manually, which is suitable for devices with unlocked bootloader or root rights, but requires caution:

1. Download the current version APK-MiuiThemeEditor file from a trusted source (e.g., APKMirror).
2. Install the file by allowing installation from unknown sources (Settings → Security → Unknown sources).
3. After installation, restart the device.

Important: Install only versions of APK that match your model and MIUI version. For example, only version 14.0.10+ will work for Xiaomi 13 Ultra on MIUI 14. Using incompatible files can lead to:

• 🐌 Slowing down the interface.
• 🖼️ Disappearance of standard wallpaper.
• 🔄 Automatic reboots.
