Owners of Xiaomi smartphones, especially previous generations of models such as Redmi 7, often face a visual discrepancy of standard emojis when communicating with iOS users. The standard set of Android characters used by default in the shell of MIUI, significantly differs from the usual “apple” emoji, which sometimes leads to misunderstanding or simply looks unaesthetic, the solution to this problem lies in the plane of system customization, namely, replacing the system font responsible for rendering graphic characters.
The procedure for installing iOS emoji on Redmi 7 does not require obtaining superuser rights (root) or complex flashing of the device, if you use the method of replacing the font file through the developer menu or third-party tools. It is important to understand that replacing the system file Emoji.ttf is an interference with the operating system, so before starting any manipulations you need to create a full backup of important data. In this article, we will discuss safe ways to transform the visual style of your smartphone.
It is worth noting that Xiaomi Redmi 7 is based on an architecture that allows you to configure the interface with a lot of flexibility, but the version of Android (usually 9 Pie for this model) imposes certain restrictions on the integrity of system files. We will use the method that has proven to be the most stable for devices with a shell MIUI 10-12. It is critical to download a font file that is compatible with the version of Android 9 to avoid the appearance of squares instead of characters.
Why Android and iPhone emojis look different
The fundamental difference in displaying emojis is how operating systems interpret Unicode codes. When you send a message with the symbol "smile", the server is not a picture, but a digital code. The receiving party (smartphone) reads this code and renders the corresponding image using its own system font. In the case of iOS, this is the font Apple Color Emoji, and in Android, Noto Color Emoji or its modifications from the manufacturer.
Redmi 7 users see Google's standard set as flatter and more geometric than Apple's gradient and three-dimensional characters. To change that perception, we need to swap the font file in the phone's system partition for the file containing Apple's graphics, which allows you to keep your correspondence fully compatible, but change the visual shell of the characters on the recipient's device if it also has the corresponding font installed, or just please your eye in local applications.
However, technical limitations should be considered. Some applications, such as Telegram or Viber, can use their own emoji sets, ignoring system settings. In such cases, replacing the system font will not affect the display of characters within these specific programs, since they use built-in resources to provide cross-platform. However, in SMS, WhatsApp (partially) and system notifications, changes will be visible immediately.
⚠️ Warning: Replacing system files may cause the interface to work in an unstable way. Make sure that the battery level is at least 60% before starting the procedure.
Preparation of the device and necessary files
The first step in the customization process of Xiaomi Redmi 7 is to prepare the workspace and download the required components. You will need a stable Internet connection to download files and a file manager with extended access rights if you plan to manually install. The most popular and proven solution for process automation is the zFont 3 application available from the official Google Play store.
If you choose the installation path through a dedicated application, the process is greatly simplified. the program will find a compatible emoji package for your version of MIUI and offer a step-by-step algorithm of actions. In the case of the manual method, you will need to find and download an Emoji.ttf file or NotoColorEmoji.ttf with graphic design in the style of iOS 14/15, adapted for Android 9.
It is also highly recommended to enable the display of hidden system files in your file manager settings.This will allow you to navigate the directory structure if you need to manually check for backups or clear the font cache after installation.Without this step, finding the right directories can take a considerable time.
- 📱 Xiaomi Redmi 7 with unlocked bootloader (preferably, but not necessarily for the zFont method).
- 💾 zFont 3 or a reliable source analogue.
- 📂 File Manager with access to the root system (for example, MT Manager or Root Explorer).
- 🔋 Battery charge above 60% to prevent shutdown during process.
💡
Before installing new fonts, take screenshots of important correspondence, as after changing the font, old messages can be displayed with new characters, which will change their visual appearance.
Installation method through the application zFont 3
The safest and most recommended method for Redmi 7 users who don’t want to go deep into system files is to use the zFont 3 app. This tool automatically determines your device model and operating system version, suggesting the most suitable installation method.
The installation process in the application takes several steps. First, the resource pack is loaded, then the application applies the font configuration. Some versions of MIUI may require a stub theme, which the application will also prompt you to install. Follow the instructions on the screen, press the Apply button and select a method marked as "Recommended" for your model.
Once the settings are successfully applied, the system may request a reboot. If the automatic reboot does not occur, manually perform it through the off menu. Once you turn on your smartphone, you will notice that the standard yellow round emojis have changed to Apple-style gradient images. Check the display in the message input field and in the system notifications.

Manual System Font Replacement (for Advanced)
For users who prefer full control of the system or are unable to use third-party installers, there is a manual replacement method. This method requires root rights or special debugging modes available through ADB. You need to find the NotoColorEmoji.ttf file in the /system/fonts/ or /system/media/fonts/ directory and replace it with a pre-downloaded analogue from iOS.
Before replacing the original file, the original file must be renamed (for example, NotoColorEmoji.ttf.bak) so that in case of an error, the system can be returned to its original state. After copying the new file, you must change its access rights (Permissions) by setting the values rw-r----644, which corresponds to reading and writing for the owner and reading for the group and others.
After all the operations of replacing and configuring access rights, the device must be fully restarted. If the smartphone is switched on correctly and displays new emoji, the procedure was successful. Otherwise, if the device is stuck on the MI logo, you will need to download to Recovery mode and restore the original font file from the backup.
| Parameter | Original file (Android) | Replacement file (iOS Style) | Requirements |
|---|---|---|---|
| File name | NotoColorEmoji.ttf | NotoColorEmoji.ttf | A perfect name match. |
| Location. | /system/fonts/ | /system/fonts/ | Root access required |
| File size | ~15-20MB | ~20-25MB | Depends on the version. |
| Access rights | rw-r--r-- (644) | rw-r--r-- (644) | After the replacement, |
⚠️ Note: When you manually replace files, a Permissions error is almost guaranteed to make the system impossible to boot.

Addressing problems and conflicts
When installing an iOS emoji on Xiaomi Redmi 7, users may encounter a number of common problems, the most common being the appearance of “squares” or empty spaces instead of emojis. This means that the installed font does not contain the full set of Unicode characters used by your version of Android, or the font file is corrupted when downloading. The solution is to find another version of the font specifically marked as compatible with Android 9.
Another common problem is ignoring changes to certain apps. As mentioned earlier, messengers like Telegram use their own graphics libraries, in which case no system settings will help change the look of emoticons inside the app, as this is programmed by developers to ensure uniformity across all platforms, only waiting for updates to the app itself or using modified clients (which may not be secure).
You may also have conflicts with MIUI design themes, and if you use a third-party theme, it can force the system fonts to replace them with its own resources, so you either have to drop the theme or find a theme that already has the emojis you want integrated into it, and you can check this by temporarily turning on the standard Classic theme and evaluating the result.
- 🚫 Squares instead of smileys – incompatibility of the font version with Android 9.
- 📱 Changes not visible in Telegram – the app uses internal resources.
- 🎨 Theme knocks down settings - the conflict of customization MIUI.
- ⚡ Fast battery consumption – rare, but possible with incorrect operation of the font engine.
💡
If after all the manipulations, the emoticons have not changed, try clearing the cache of the application "Themes" and "System UI" in the application settings, then restart the device.
Security and Return to Original Settings
While replacing the font is considered one of the safest procedures for modifying Android, the theoretical probability of software errors persists. The main risk is the possibility of damaging the system partition if the file writing process was interrupted or if the file was incorrect, which is why having a backup is a must.
To return to the factory font settings on Redmi 7, you just need to reset the theme settings to the standard. In the Themes app, select a profile, click on a classic theme and apply it. If you used the manual root-right replacement method, you will need a file manager to restore the original NotoColorEmoji.ttf.bak file, renaming it back and restoring access rights.
In extreme cases, when the system stops responding correctly, a full reset to factory settings (Wipe Data) will help.This action will delete all user data, so regular backup to the Mi Cloud service or locally to the computer is the best security practice in any experimentation with the system.
⚠️ Warning: Never interrupt the system file replacement process or turn off the phone until you make sure the file is fully recorded and access rights are applied correctly.
Impact on the guarantee
Impact on Redmi 7 performance
Many users worry that installing graphically more complex fonts can slow down a device, especially a Redmi 7 with a Snapdragon 625 processor. Practice shows that the impact of replacing an emoji font on the overall performance of the system is negligible. Android is optimized to work with various font engines, and rendering color emojis does not create a significant burden on the CPU.
The only noticeable change may be the amount of RAM it takes up, as Apple’s color fonts take up more space than standard monochrome or less detailed counterparts. However, for modern versions of MIUI, this increase is measured in megabytes and does not affect the speed of switching between applications or the operation of background processes.
This way, you can safely set your desired visual style without fear of significant performance loss.The only real limitation is version compatibility, as mentioned earlier, not the hardware capabilities of the smartphone.
