Personalizing the look of a smartphone is not just a matter of aesthetics, but also a way to make the device more comfortable for the eyes. Owners of the popular Redmi 9 Pro model often look for ways to diversify the standard MIUI interface, starting with replacing the system font. Standard font can seem too small, pale or simply boring, especially if you spend a lot of time reading news or books from the screen.
Changing typography in Xiaomi has its own features that distinguish it from pure Android. It uses a powerful shell that allows you to implement changes at a deep level without having to get superuser rights or flash it back, but to do this correctly and not disrupt the readability of the interface, you need to understand exactly where the settings are hiding and what the restrictions are.
In this guide, we will take a look at all the methods available, from standard settings to unique designs through special applications, how to adapt text to your vision and why some fonts may not display correctly in certain menus, allowing you to fully adapt Redmi 9 Pro to your individual needs.
Standard font settings in the MIUI system
The first and safest way to change the visual perception of text is to use the built-in tools of the system. In Redmi 9 Pro, this is the settings menu, where you can adjust not only the style, but also the size of the characters. First, you need to go to the Settings section, which is represented by the gear icon on the desktop or in the notification curtain.
And then you go through the Screen menu, where you have all the parameters that you want to display, and this is where the Text Size is, which allows you to use the slider to increase or decrease the size of the letters throughout the system, and this is especially true for visually impaired users who don't think standard settings are good enough.
It's important to note that changing the size of the text affects the layout of many applications. Some programs can adapt instantly, while in others the interface can "go" or become less convenient for navigation. Therefore, it is recommended to select the size by sampling, checking the display in commonly used applications such as instant messengers or browsers.
⚠️ Warning: Excessive text size can cause some buttons or menu items to stop fitting on the screen, requiring scrolling or hiding behind the limits of visibility.
To fine-tune the style, in addition to the size, the system suggests choosing one of the preset shapes. There are usually few of them, and they have standard names, but even among them you can find a variant that will read more pleasantly than a standard Roboto or MI Sans.
💡
Use the “Enlarged Text” function in the “Advanced Settings” → “Special Opportunities” section if you’re missing a standard size slider – it’s a visually impaired mode that ignores some of the app’s limitations.
Using the “Themes” app to change the font
The most popular and functional tool for customization Xiaomi is the system application Themes. This is where you can find a huge library of fonts, many of which are created by independent designers from around the world. To get into this section, look for the Themes app on your desktop or in the Tools folder.
Inside the application, you need to go to the Profile tab (usually the person icon in the lower right corner) and select the Font item./browseAnd you can find the options that are available, and you can have both free and paid markings, and filters that allow you to sort them by popularity, novelty or rating, which makes it much easier to find a quality marker.
The installation process is very simple: you select the font you like, click Download and then Apply. The system will automatically restart the interface or ask to restart the device so that the changes take effect, and then the new style will appear in all supported applications, including settings, messages and contacts.
- 🎨 A huge selection of styles: from handwritten and gothic to minimalist and bold.
- 🌏 Localization: Many fonts support Cyrillic, but there are also those that display only Latin.
- 🔄 Regular updates: the catalogue is updated weekly.
Consider that the Themes app requires an active Internet connection to download content. In addition, the region of your Mi Account account can affect the availability of certain fonts. If the directory seems empty to you, try changing the region in your phone settings to India or Russia, and then clear the cache of the Themes app.
Installation of third-party fonts through APK files
If the built-in directory doesn't meet your needs, you can resort to manually installing fonts. This method requires more care, since you download files from third-party sources. You will need to find a font file with the.mtz extension (specific for MIUI) or.ttf /.otf from trusted sources.
Installer applications such as MIUI Theme Editor or zFont 3 are often required to install.mtz files, which are intermediaries to help the system recognize and apply a file that has not been officially approved by the theme store.
Direct replacement of the system file without Root rights is not possible in new versions of MIUI. However, some launcher applications or specialized utilities can emulate the font within their interface or apply it through backup and data swap.
| File type | Compatibility | I need a Root. | Risk of error |
|---|---|---|---|
| .mtz | High (MIUI) | No. | Low. |
| .ttf /.otf | Medium | Often. | Medium. |
| .apk (fonts) | Depends on the app. | No. | High-pitched |
The main advantage of this method is the ability to use unique fonts that are not in the official store. You can find the font used in your favorite game or operating system of another manufacturer and embed it in your Redmi 9 Pro.
⚠️ Note: Upload font files only from trusted resources. A file with the extension.mtz may contain malicious code if its source is unknown, which jeopardizes the security of personal data.
Where to find safe fonts?
Setting the size and fat content of the text
Visual comfort depends not only on the shape of the letters, but also on their saturation and dimensions. Redmi 9 Pro has hidden opportunities for tweaking the boldness of the text, which is especially useful for the user. AMOLED-screens where thin lines may appear blurred or dim at low brightness.
To change the fat content, there are often not enough standard settings. Some of the fonts in the theme store have variations of Bold (fat) or Light (thin), and when you choose these versions, you change the contrast of text relative to the background, which can significantly reduce eye fatigue when reading at night.
Text size is also critical. In the Settings menu → Screen → Text size, you can set a value at which the lines will not merge, but will not occupy the entire screen. The optimal size is considered to be a size at which you do not have to strain your eyesight or hold the phone too close to your face to read.
- 👁️ For reading books, it is better to choose fonts with serifs and medium size.
- 📱 For the system interface, grotesque (without serifs) average shape is preferable.
- 🌙 At night, reduce brightness and use the Reading mode for a warm hue.
And remember, the feature called "Enlarged Text" in the feature section, which forcefully scales up interface elements to make them giant, which is useful for older people, but can break the layout in some third-party applications that can't scale.
☑️ Optimizing text on Redmi 9 Pro
Problems with the Cyrillic display and
One of the most common problems with changing fonts on Xiaomi devices is the lack of support for Cyrillic. Since many font designers create them for the global market or specific language groups, you may find yourself in a situation where instead of Russian letters, “krakozyabra” or squares are displayed.
To avoid this, always check the font description in the theme store, there should be a list of supported languages or a preview with Russian text, if the preview is not available, and the font is very popular, you can install it and check it in real time, since the application takes seconds.
If the font is used, but the Cyrillic alphabet does not work (question marks are displayed), the only solution is to return to the standard font or search for an analogue marked Cyrillic. Some users try to “tweak” Russification manually, editing font files, but this requires deep knowledge and special software.
⚠️ Warning: If after installing the font, the phone stopped responding to touch or the interface is gone, press the power and volume button for a forced reboot. In Safe Mode (download with the volume button clamped) you can remove the problem font.
Also, it is worth considering that some system applications, such as Calculator or Watch, can ignore third-party fonts and use a system standard. This is normal behavior of the MIUI shell, aimed at preserving the functionality of mission-critical elements.
