Xiaomi smartphone owners often experiment with visual design by installing third-party themes from the Themes store. However, not all downloaded packages work correctly on the Redmi 7 model, which can lead to text disappearing, the appearance of “crackers” or a complete change in the system font to unreadable.
The problem is often font version conflict or the theme cache files are damaged. A standard Roboto or MiSans font can be replaced with a graphic file that does not support Cyrillic. In this guide, we will detail all the ways to restore the standard display of text, from simple settings to forced reset via Safe Mode.
Don't panic if the smartphone screen is covered with obscure characters. MIUI has multiple layers of protection and rollback capabilities. Even if the menu is completely unreadable, there are hardware button combinations and hidden menus that allow you to return factory design options without losing personal data.
Diagnostics of the problem with the display of text
Before we take action, we need to understand the scale of the problem, and if text is missing in just one application, it may be because of its internal error, but if the characters are gone throughout the system, including notifications and settings, it's a global style change, and users often accidentally activate Pocket Mode, or special features for the visually impaired that change the size and type of font.
One of the common reasons is automatic theme updates. Themes store can update the active design package, and the new version will be incompatible with the current version of MIUI firmware on Redmi 7. This leads to the fact that the system paths to font files are interrupted, and the operating system does not know which character to display instead of the missing one.
It's also worth checking if you're in high contrast mode or color inversions that visually distort the text. In some cases, the problem is software-based and involves overflowing font cache. The system simply stops loading new glyphs, leaving empty spaces or squares. Understanding the reason helps you choose the most gentle recovery method.
Recovery through theme settings
The easiest and safest way to get things back to their place is to use a built-in theme app. Even if the text on the screen looks weird, the app icons usually stay in place. You need to find an app with a brush or gallery icon called Themes or "Themes" that is logged in with a standard tap on the icon.
When you open the app, look at the bottom navigation bar. Usually, the user profile or the "My" section is in the far right corner. When you click on this tab, you'll be taken to the installed packet management menu. You'll find the "Fonts" or "Fonts" section here. Even if the item names are not readable, you'll need to look at the icons: the font is usually marked with the letter "A" or the symbol of a text document.
☑️ The algorithm of resetting the topic
Inside the font section, you need to find the active element, which will be marked with the appropriate icon or just on top of the list, and your task is to find the standard font application button. In the MIUI interface, this is often the Apply button in standard Roboto font or the Reset button, which returns the factory design settings, and after pressing the screen can blink, and the text should return to normal.
Use of safe mode for discharge
If the smartphone interface is completely unreadable and you can’t get into the settings menu, Safe Mode will come to the rescue, in which the operating system only loads with basic drivers and standard fonts, ignoring all user themes and third-party modifications, a perfect way to “cure” the phone when the visual interface is broken.
To enter Safe Mode on Redmi 7, you need to do the following: First, turn off your smartphone completely, press the power button and select the appropriate item (orientating to the off icon). After the screen goes out, press the on button again. As soon as the Redmi or Mi logo appears, release the power button and immediately press the volume down button (bottom swing).
Keep the volume button until the desktop is fully loaded. The bottom left corner of the screen should show "Safe Mode" or "Safe Mode." In this state, all your themes will be turned off, and the font is guaranteed to become standard. Now you can safely go to the settings, delete the problematic theme or reset the font settings, knowing that the text is displayed correctly. To exit safe mode, just reboot the device in the usual way.
⚠️ Warning: Some features, such as Wi-Fi or mobile network, will not work in Safe Mode, depending on the version MIUI. Don't be afraid of the lack of Internet connection, it's normal for the system to diagnose. Your goal is just to restore the font.
Setting the size and style of the font
Once a standard font is successfully returned, it is recommended to check its parameters. Sometimes the text returns, but its size remains changed, making it uncomfortable to use a smartphone. MIUI has flexible typography settings that allow you to adapt the display to your individual preferences without losing readability.
To access these settings, go to Settings → Screen → Text Size. Here you will see a slider that changes the size of the font throughout the system. Also, this menu often provides font style choices if you have multiple system packages installed. Make sure you choose either Default or Classic to avoid future conflicts.
Special attention should be paid to the "Enlarged Text" function for the elderly or those with poor vision. If it is turned on accidentally, the font may look too bulky. Turn off this switch if it is active to return the proportions of the text to standard values. Correctly calibrating the font reduces the load on the eyes and improves the perception of information.
Compatibility table of fonts and versions of MIUI
Not all fonts work equally well on different versions of the operating system. Redmi 7 was officially updated to the version of MIUI 11 based on Android 9, but many users install custom firmware or newer versions of MIUI informally.
The table below shows what type of fonts work best on different software modifications for this model, and using.mtz extension fonts from newer versions of MIUI on older firmware often leads to the problems described.
| MIUI version | Basic OS | Recommended format | Compatibility status |
|---|---|---|---|
| MIUI 10 | Android 8.1 | Systemic (.ttf) | Complete. |
| MIUI 11 | Android 9 | Topics (.mtz) | Tall. |
| MIUI 12+ (Custom) | Android 10+ | Mixed | Requires a check-up. |
| Global Stable | Anybody. | Official store | Guaranteed. |
If you use custom firmware, make sure that the font files in the system partition have not been modified by third-party assemblers. Often, these builds contain cut-out localization files, which leads to the disappearance of the Cyrillic alphabet, in which case only the firmware of the device with a clean official version of the software will help.
Removing cache and resetting design settings
If simple methods didn't help, it's possible that the phone's memory has accumulated erroneous cache data.The system stores temporary font files to speed up their loading, and if those files are corrupted, the new font won't apply correctly. UI» often solves the problem.
To do this, go to Settings → Apps → All Apps. Find Themes in the list. Click on it and select Memory or Storage. There you will see Clear Cache and Clear Everything. Click on Cache Clear first, check the result. If it doesn't work, use Delete Data Completely (this won't delete your personal photos or contacts, just the theme settings).
⚠️ Note: When you clean the Topics app data, all the themes you download will be reset to factory ones. Make sure you remember passwords from important accounts, as the password entry screen can also temporarily use the system font.
Once the cache is cleared, make sure to fully reboot the device, not just turn off and turn on the screen, but complete the restart cycle through the power menu, allowing Android to re-scan the file system and correctly register standard font files in the registry.
