Xiaomi and Redmi smartphone owners often face the desire to personalize their device interface beyond standard capabilities. Changing the font is one of the most effective ways to make menus and text messages unique without resorting to complex system modifications. The default font installed in the MIUI shell or the new HyperOS may seem boring or not readable enough for some users, especially given the features of AMOLED screens.
The process of replacing typography on Xiaomi devices does not require root access or flashing the device. The whole procedure takes only a few minutes and is performed using the system’s regular tools or using simple third-party utilities. To install custom fonts in.ttf or.otf format, you need to have a Mi Account account, even if you use third-party applications to activate them. This is an important requirement for security and synchronization of the the design theme.
In this article, we will take a look at all the available methods, from the official theme store to advanced file installation through an engineering menu or special applications. You will learn how to avoid common mistakes, such as the appearance of “squares” instead of letters, and how to return everything back if the result does not suit you.
Official method through the "Themes" app
The easiest and safest way to change the spelling is to use the built-in Themes app. This is Xiaomi's regular tool, which is pre-installed on all the brand's devices. To get started, you need to open the app and go to the Profile tab, which is usually located at the bottom right of the screen, and here is the Font button, clicking on which will open the catalog of available options.
The catalogue features a variety of free and paid fonts. Free options are often labeled or found under the Recommended Style section. Once you select your preferred style, click Download and then Apply. The system will automatically restart the interface, and changes will take effect in all supported applications, including the settings menu, messages and browser.
But the official method has its limitations: the directory can be limited to regional account settings, for example, in the region of Russia, the choice may be less than in the region of India or Singapore, and many beautiful fonts are paid or require a premium subscription, and if the standard directory does not suit you, you will have to resort to alternative methods.
⚠️ Note: When downloading fonts from unverified sources in the Topics app (if you have changed region), make sure the author is highly rated to avoid installing malicious themes masquerading as fonts.
Use of third-party applications for font installation
If the built-in directory doesn’t offer the desired variety, specialized apps from the Google Play Store come to the rescue. One of the most popular and reliable solutions is the zFont 3 app. It allows you to install fonts that are not available in the official Xiaomi store, including popular system fonts from Samsung, iPhone or Google.
The principle of these programs is to create a temporal theme. The application downloads the font file, packages it in the MIUI theme format and applies it through the theme installer system. You do not need to manually copy files to the system folders. You just select the font in the list, click Apply, select the model of your phone (for example, Redmi Note 12 or Xiaomi 13) and follow the instructions on the screen.
An important advantage of using zFont or analogues (like Fonts Manager) is the ability to preview. You can type your text into a special field and see how it will look in different styles before installation, which saves time and eliminates the need to constantly change the settings back and forth.
💡
Before installing the font through a third-party application, take a screenshot of the current display settings or save the name of the standard font so that in case of problems, you know what exactly needs to be restored.
Manual installation of TTF and OTF files
For advanced users who want to use a specific font file downloaded from the Internet (.ttf or.otf formats), there is a method of manual installation, which gives full control over the appearance of the system, but requires care. First, you need to download the font file itself from a reliable source, for example, from the Google Fonts portal or specialized forums.
Once the file is uploaded, it needs to be stored in the phone’s memory. The process depends on the version of MIUI. On newer versions (MIUI 12.5, 13, 14 and HyperOS), direct installation through the file manager may not work without third-party software. It is recommended to use the same zFont 3: select the Local tab, find the downloaded file and apply it. An alternative, more difficult way is to use the Import Font function in some versions of the Topic application, if it is available in your region.
When you manually install it, it is critical to check the font encoding. If the font does not support Cyrillic (Russian), instead of letters, you will see empty squares or question marks. Always check the description of the file before downloading for Cyrillic support.
What to do if the font is not used?
Size and style of text in MIUI and HyperOS
Often the problem of readability is not solved by changing the font itself, but by adjusting its size and boldness. MIUI And HyperOS offers flexible typography settings that allow you to tailor the interface to the user's vision. → Screen. → Size of text.
There's a slider that regulates the scale of the letters. The slider's right-hand motion increases the text, making it more visible, which is especially true for people with low vision or when using a smartphone in the bright sun. The left-hand drive allows you to fit more information on the screen, which is appreciated by users of flagships with a diagonal of 6 inches or less.
Special attention should be paid to the setting of the Fat text. → The screen often has a Fat Text switch, which activates all system inscriptions with more contrast and saturation, which can completely eliminate the need for third-party fonts.
| Parameter | Location on the menu | Impact on the system | Recommendation |
|---|---|---|---|
| Size of text | Settings → Screen → Text Size | Scaling the font in all applications | Optimal 3-4 divisions |
| Bold text | Settings → Screen → Fat Text | Increases the saturation of symbols | Energize for AMOLED |
| Font system | Themes app → Profile | Changes the spelling of letters. | Only verified sources |
| Reading mode | Settings → Screen → Reading Mode | Changes color temperature. | Use it in the evening |
Possible problems and solutions
When experimenting with system fonts, users may encounter a number of technical problems, the most common being the appearance of “krakozyabr” or empty squares instead of letters in Russian-language menus and applications, which occurs when the installed font does not contain the Cyrillic character table, and the problem of returning to the standard font through the Themes app is solved.
Another common problem is that the font is not displayed correctly in individual applications, such as WhatsApp, Telegram or Instagram. Some programs use their own text rendering engines and ignore the system settings of the font, in which case you can change the view of text inside the application only through its own settings, if such a feature is provided by the developer.
There may also be a malfunction in the interface: “got” layout, overlaying text on buttons or disappearing icons. This often happens when installing fonts that are not adapted to the high-resolution screens of modern Xiaomi smartphones. If the interface has become unreadable, use a blind method of entering safe mode or quickly changing the topic through the notification curtain (if there is a themes widget).
☑️ Checklist before installing font
⚠️ Warning: If after installing the font, the phone stopped responding to touch or the image disappeared, try to perform a forced reboot by clamping the power button on the phone. 10-15 In seconds. 99% This will return access to the system.
How to return the default standard font
If you're tired of experimenting with the look or the new font is uncomfortable, it's very easy to get it back, so you don't have to drop your phone to the factory settings, you just have to reopen the Themes app, go to Profile and select Fonts.
At the top of the screen, you’ll see the default Restore Font button, or simply select Classic font (or Roboto, depending on the OS version) from the download list and click Apply.The system will instantly return the original letter mark, and the interface will become what it was when you bought the device.
It is worth noting that after returning to the standard, it is recommended to restart the device, which will clear the font rendering cache and ensure that any visual artifacts that may have remained from the previous custom font will be eliminated.
💡
Returning to the standard font is a feature that doesn’t delete your personal data, contacts or apps, and you shouldn’t be afraid of losing information when you change the font.
