How to change emojis to Xiaomi: Replacing emojis in MIUI

Modern communication is impossible without the use of emotional symbols that convey mood where words seem dry. Xiaomi smartphone owners often face the desire to personalize the device, from wallpaper to system interface elements. However, the standard set of emojis preinstalled in the shell of MIUI or HyperOS can seem boring or just different from what users of other platforms are used to.

Changing graphical character display is not just a cosmetic procedure, but also a way to make correspondence more personal. The process of replacing standard icons with alternative sets requires an understanding of how the Android operating system handles fonts and graphic resources. In this article, we will discuss legal and secure customization methods that do not require deep technical knowledge.

It should be noted that the built-in tools of the system without obtaining advanced access rights to change the "picture" of the emoji in most cases, but there are workarounds that allow you to achieve the desired visual effect. We will consider the use of themes, installing specialized fonts and working with system files for advanced users.

Features of the emoji system in the shell of MIUI

Xiaomi’s MIUI shell is based on the Android operating system, where the system font is responsible for displaying graphic characters. By default, devices use the Noto Color Emoji font or a modified version of it adapted to the interface design code. This file determines how a smiling face, heart symbol or animal image will look on your smartphone screen.

The main difficulty is that system files are protected from direct modification by ordinary users. Trying to replace the font file in the system partition without the appropriate rights can lead to unstable interface operation or even bootloop (cyclic reboot).

It’s important to understand that when you send a message in messengers (like WhatsApp or Telegram), the recipient will see the emoji according to their device, not yours.However, in system notifications, alarm clock, calendar and some native Xiaomi apps, changing the font will allow you to enjoy the new visual style all the time.

⚠️ Warning: Before any manipulation of system files or installing third-party fonts, be sure to create a full backup of the data.Incorrect replacement of the system font can make text on the screen unreadable.

There are several levels of access to change graphics: the first level is the use of built-in personalization features, the second is the installation of third-party applications, and the third is a deep modification of the system with Root rights, the choice of method depends on your smartphone model and the version of the operating system installed.

Change of smiles through the installation of themes

The easiest and safest way to change the look of the interface, including app icons and sometimes system elements, is to use the Themes app. Xiaomi’s Mi Theme Store catalog features thousands of design choices created by both official designers and the community. Some themes contain their own emoji sets that replace standard images.

To find the right design, you need to open the Topics app and search. Type in keywords such as "Emoji", "iOS style", "Android 12 emoji" or "Color icons" into the search bar. Then go to "All" or "Themes" to filter the results. Pay attention to the topic preview: often authors indicate in the description or on screenshots whether the set of emojis changes.

The process of installing the theme is simple: click Download and then Apply. The system can suggest choosing which elements to use: lock screen, wallpaper, system icons and fonts. Make sure that all points are marked to maximize the chances of replacing graphic characters. If after applying the theme, the smiley messages remain the same, then this theme changes only the application icons, not the system font.

• 🎨 Open the Themes app on the home screen or in the Tools folder".
• 🔍 Search for “iOS emoji” or “emoji style” to find alternative sets.
• 📥 Select a High Ranked Theme and click Download, then Apply.
• 🔄 Restart the device if the changes do not take effect immediately.

The effectiveness of this method varies depending on the version of MIUI. In newer versions of the shell (MIUI 13, 14, HyperOS), the security policy has become stricter, and many themes may not be eligible to replace the system fonts.

Use of third-party fonts and keyboards

If the themes didn't work, you can try replacing the system font as a whole. Many fonts contain built-in emoji sets. To do this, you will need to download a font file with the.mtz extension (for MIUI) or.ttf /.otf from trusted sources. Install.mtz fonts through the same Theme app: click on the user profile, select Fonts and import the file.

An alternative and often more efficient way is to install a third-party keyboard: Keyboards like Gboard, Facemoji or Kika Keyboard have their own emoji libraries. While emojis will remain standard in system notifications, you will see and use the typeface you choose in the typing process.

To install the keyboard, download the app from Google Play Market. Once installed, the system will prompt you to activate the new keyboard. Go to the language and input settings (Settings → Additional settings → Language and input) and select the installed application as the main one. In the keyboard settings, you can often find the Smiles or Emoji section where you can choose the style (for example, iOS style, Android 11 style, etc.).

There is also a method of root-free type-swapping via ADB (Android Debug Bridge), but it requires a computer connection, which allows you to embed the font into the system without any restrictions, but it is difficult for beginners. A more affordable option is to use helper apps like zFont 3, which automate the process of installing fonts through temporary application of themes.

Advanced method: replacing system files with Root

For users who want to make sure to change system emojis across all apps and notifications, often the only solution is to obtain SuperUser (Root) rights.This process unlocks access to the system partition /system where the font files are stored.

The main file responsible for the emoji is usually called fonts.conf or is in the fonts.zip archive inside the /system/fonts or /system/framework/framework-res.apk folder. To replace, you will need a root-enabled file manager, such as Root Explorer or MT Manager. You need to find the original emoji file (often NotoColorEmoji.ttf) and replace it with a modified version, renaming the new file exactly as the original.

adb shell


su




mount -o rw,remount /system




cp /sdcard/NewEmoji.ttf /system/fonts/NotoColorEmoji.ttf




chmod 644 /system/fonts/NotoColorEmoji.ttf




reboot

The above is an example of a replacement command via ADB, but you can do the same through the file manager on the phone itself. It's critical to make a copy of the original file before you replace it. If the new font turns out to be broken or incompatible, you can restore the original through Recovery mode, otherwise the phone may stop loading.

⚠️ Warning: Getting Root rights (unlocking the bootloader) may cause Google Pay (Mir Pay) banking applications and services to stop working.

Compatibility and Display Problems

Even after a successful font replacement, users may encounter artifacts, some emojis may appear as empty squares or question marks, because the new font may not contain all the Unicode characters found in the original system, especially new emojis added in the latest versions of Android.

Another common problem is sizing dissynchronization: Smileys from another set (like iOS) can be significantly larger or smaller than text, which disrupts the layout of messages. In some cases, this is solved by scaling settings in Settings → Screen → Text size, but not always.

It is also worth considering that when you update the operating system, all changes made manually to the system files will be lost. OTA-Update (over air) overwrite modified partitions with original firmware files. You will have to repeat the replacement procedure after each major update MIUI.

If you notice that the font has become fuzzy or "soapy," it may not match the pixel density of your screen (DPI). Always try to select font files tailored specifically to your screen resolution or universal vector versions, if available.

Alternative solutions and widgets

If a system replacement seems too complicated or risky, widgets can be used. On the home screen or lock screen, you can place widgets with beautiful watches and dates that use their own sets of icons and smileys. This will not change the smileys in correspondence, but will allow you to personalize the appearance of the smartphone.

There are also dedicated launchers, such as Nova Launcher or Microsoft Launcher, that allow you to customize application icons in detail. While they don’t completely change system emojis, using the Icon Pack in conjunction with the launcher creates a completely redesigned interface where graphic elements look uniform and stylish.

💡

Use the “Second Space” feature on Xiaomi to test a new theme or font on a separate profile without affecting the main data and settings of your main account.

For minimalist lovers, there are monochrome sets of fonts and icons that turn bright emojis into black and white contours. This not only changes the style, but can also positively affect the screen time in E-Ink mode (if you have such a mode in your model) or simply reduce visual noise.
