How to change the font Xiaomi Redmi 9 with NFC

Personalizing the smartphone interface is one of the easiest ways to make the device more comfortable and enjoyable. Owners of the popular Xiaomi Redmi 9 model often wonder how to change the standard system font to something more original or simply more readable. Fortunately, the MIUI shell provides ample opportunities for customization without the need for root rights or complex firmware reflashing.

Unlike many other manufacturers, the Chinese giant allows you to change not only the size, but also the style of the display of letters using a built-in theme store, especially for people with impaired eyesight who find the standard font too thin or small, and for aestheticists who want to stand out. The change takes only a few minutes, if you know the correct algorithm of actions.

It is worth noting that the Xiaomi Redmi 9 with or without NFC is not fundamentally different in this context, since the interface configuration does not depend on the presence of contactless communication. However, the presence of the NFC module can be important for other personalization functions, for example, for writing tags with macros, but now we will focus on the visual component of text in the system.

Before you start installing new styles, it's important to understand that all the changes are made through the Themes system application, which is a centralized hub where wallpaper, sounds and, of course, fonts are stored. Some users mistakenly search for these settings in the Screen or Display menu, but there you can adjust only brightness and resolution, not typography.

Standard methods of changing the font through the Topics app

The main and most secure way to change the display of text is to use the official directory of Xiaomi Themes. This store has thousands of free and paid options that are tested for compatibility. To get started, you need to open the Themes app on the home screen or in the Tools folder.

When you start the app, look at the bottom navigation bar, and you'll find the Profile tab, or the little guy icon that leads to your personal account, and that's where the Fonts section hides the entire library of styles available, and the system will offer you some popular options, but the full directory will open when you click "Get More Fonts."

When you choose a new style, the system will show a preview where you can see how the text will look in different applications. This is a very convenient feature that allows you to assess readability before installation. If you like the font, click the button "Download" and then "Apply." The smartphone may ask for a reboot, although on MIUI 12 and later changes are often applied instantly.

⚠️ Note: When installing fonts from third-party, unofficial sources, the risk of getting a virus or disrupting the stability of the system is minimal, but there is. Always check the author's rating of the topic and reviews of other users before downloading.

If you see squares or characters instead of letters after installation, then the style does not support Russian, in which case it is better to go back to the standard font and choose another option marked with "Cyrillic" or "Russian".

Advanced text display settings

In addition to changing the style of letters, Xiaomi Redmi 9 allows you to fine-tune the display settings. This is especially useful if the standard fonts seem to you not contrasting or clear enough. There are hidden features in the screen settings menu that are often ignored by users.

To access the additional options, go to Settings → Screen → Text Size and Fat. Here you can not only increase the size, but also make the font bolder. Thickened letter lines significantly improve readability in bright sunlight or for people with farsightedness.

You also need to pay attention to the feature "Enlarged Text," which differs from simple zooming in that it rearranges some interface elements to make them more user-friendly, and activating this option can change the location of buttons in some system menus, adapting them to large fonts.

• 🔹 Text fat: slider allows you to adjust the saturation of the font from thin to very bold, which affects contrast.
• 🔹 Scaling: Resizing the font affects all applications that support system display settings.
• 🔹 Dark theme: Turning on dark mode often changes font rendering, making them softer for the eyes at night.

Remember that excessive font size can cause text in some applications to be cropped or overlaid on other elements, and in such cases, it is recommended to zoom back to the default value or look for alternative applications with flexible interface settings.

💡

Use the “Enlarged Text” feature only if standard zooming isn’t enough, as it can disrupt the layout in some third-party applications.

Manual installation of third-party fonts

If Xiaomi's built-in directory doesn't suit your tastes, you can always install the font manually, which requires downloading a.ttf or.mtz file from trusted sources on the Internet, a process that's a little more complicated, but opens up millions of fonts from around the world.

To install the.mtz file (MIUI theme format), you need a file manager. Place the downloaded file in the MIUI/theme folder on the internal drive. Then, in the Topics app, go to the Mys → Fonts section, and the downloaded file should appear. Click on it and select Apply.

The situation is different with.ttf installation: Direct installation through the theme menu may not work without using special tools. One popular method is using the zFont 3 app available on Google Play, which automatically adapts the font to your version of MIUI and helps you apply it through backup or use of the "Mi Pilot" mode.

The path for manual copying of files topics:


Internal Storage/MIUI/theme/

When using third-party utilities, be careful about permission requests. The application may need access to storage and system settings. This is necessary to properly replace the system font files. After applying the changes, be sure to restart the device so that the new style is fixed in all parts of the system.

Comparison of popular system fonts

Choosing a font is a subjective matter, but for the Xiaomi Redmi 9 with its FHD+ resolution screen, some styles are better than others. Below is a table that helps you navigate the main characteristics of popular options available in the theme store.

Roboto is the standard for Android and is optimized for screens of all resolutions. It provides better legibility in a small pin. If you want to add personality, Montserrat is a great choice for headlines and menus, while maintaining rigor.

Retro style lovers will love pixel fonts, but it is worth considering that on high-pixel density screens like the Redmi 9, they may look too small, in such cases, it is recommended to increase the overall text size in the system settings.

Solution and troubleshooting

When changing fonts, users may encounter a variety of problems, one of the most common being "squares" instead of letters, which means that the font chosen does not contain Cyrillic characters, the solution being one: search for fonts marked Cyrillic or return the standard font through safe mode if the system has stopped responding to touch.

Sometimes, after you install a new style, the interface can go, and the text on the buttons can crop or overlap images. This is due to different word lengths in different languages. If the problem is critical, press the power button and select a reboot. If that doesn't help, go to Settings → Themes → Profile → Fonts and apply the font "Classic" or "Default".

Another problem is the inability to use the font. The Apply button may be inactive or give an error. Often this is due to a crowded cache of the Themes app. Clear the application data through the Settings menu → Apps → All Apps → Topics → Clean. After that, try again.

• 🔸 Application error: check for free space on the internal drive, temporary files require space.
• 🔸 Text not read: font does not support Russian, urgently replace it with standard.
• 🔸 Brake interface: complex animated fonts can load the processor of budget models, use static options.

⚠️ Warning: If the phone stops turning on or is not working properly after installing the font, try to boot into Safe Mode. To do this, press the volume button when you turn on. In Safe Mode, third-party fonts are turned off, which will remove the problem file.

The impact of fonts on autonomy and performance

Many users fear that changing the font could have a negative impact on battery life. In fact, static fonts (ordinary.ttf) have little impact on power consumption, and are loaded into memory when the system starts and no longer require processor resources to render.

But that changes if you use live fonts or themes with complex text animations, and in these cases, the Redmi 9 GPU has to constantly redraw characters, which can lead to increased charge consumption and heat of the device.

Also, some optimized fonts can speed up the interface. For example, sans-serif fonts render faster on mobile than complex decorative designs. On the Helio G80 processor that is installed in Redmi 9, the difference can be noticeable when you scroll through long contact lists or messages.

💡

Static fonts don’t affect the battery, while animated themes with text can cut battery life by up to 10-15%.

In conclusion, changing the font to Xiaomi Redmi 9 is a safe and effective way to update the look of your smartphone. Experiment with styles, but always leave the option of quickly returning to factory settings in case of unforeseen situations.
