How to see blurred text on Xiaomi: recovery methods

Users of Xiaomi, Redmi and Poco smartphones often face a situation where important information in applications or system messages is hidden from view.This can be caused by a font rendering error, specific privacy settings, or a software failure in the shell of MIUI and HyperOS. Instead of readable text, the user sees a set of squares, black stripes or blurred areas, making it impossible to use the device to its fullest extent.

There are several approaches to solving this problem, ranging from simple manipulation of display settings to complex debugging procedures through ADB. It is important to understand that the nature of the appearance of “blurred” text can be different, from the banal absence of fonts in the system to damage the message database. In this article, we will discuss all known ways to fix the defect, focusing on the security of your data.

Before we take action, we need to determine the extent of the problem. If the text is not read in only one application, it is likely to be the cache or compatibility of the Android version. If the problem is systemic and affects the settings menu or SMS, a deeper intervention in the operation of the operating system will be required.

Causes of Artifacts and Hidden Text

The main reason for unreadable characters is often the conflict between the installed font and the system requirements of applications. MIUI shells allow you to deeply customize the appearance, but third-party themes or fonts from the GetThemes store may not contain all the necessary glyphs, as a result, the system replaces the missing characters with “stubs” in the form of squares or dots.

Another common cause is a clipboard overflow or damage to the SQLite database where messages are stored. When an application tries to count a record that is not sized or encoded as expected, it can output void or graphical noise, which often happens after an incorrect backup recovery or reset.

Also worth mentioning is privacy features: new versions of HyperOS have algorithms that hide the content of notifications on a locked screen or in preview if the privacy mode is enabled, which the user may mistakenly mistake for a technical malfunction.

• 📱 Lack of support for Unicode characters in the current interface font.
• 💾 Damage to the cache files of a particular application or system component.
• 🔒 Activated “Hidden Content” mode in notification settings.
• ⚙️ Conflict of rendering libraries versions after firmware update.

⚠️ Note: If the text stops reading immediately after installing a third-party theme, first of all return the standard design in the application "Themes».

Sometimes the problem is hardware acceleration. Some graphics drivers in conjunction with Snapdragon or MediaTek processors may not properly render text layers when the option “Accelerate GPU rendering” is enabled.

Basic display and font settings

The easiest and safest way to eliminate artifacts is to check the font settings. Go to the Settings menu → Screen → Font and select a standard system font, such as Roboto or MI Sans. This action will force the text engines of the system to restart.

If the font replacement didn't help, try resizing the text. Moving the slider in the Settings menu → Screen → Text size can cause the system to redraw the interface, eliminating visual bugs. Sometimes changing the density of the DPI helps, but it requires caution, as it can move interface elements beyond the screen.

💡

Use Read mode only in third-party apps. In Xiaomi system menus, it can cause text color inversions, making it unreadable on a white background.

A dark theme is an important aspect. In MIUI, the implementation of a dark theme sometimes conflicts with applications that are not optimized for it. If the text becomes invisible (merges with the background) or blurred, try switching the theme to light through the control center or in Wallpaper and personalization settings.

For users who actively use text augmentation for the visually impaired, there is a risk of overlapping elements, in which case the text may overlap with other interface blocks, creating an illusion of blurring. Check whether the feature "Enlarged Text" is included in the special features section.

Using Developer Mode for Diagnostics

If standard methods fail, you need to delve into the system settings. This requires activating the developer menu. Go to Settings → About phone and quickly press 7-10 times on the MIUI version or OS version until the activation notification appears.

In the Extended Settings menu! → For developers, we are interested in the hardware acceleration section. Find Disable HW overlays or Hardware Rendering Acceleration. Experimental switching of these parameters allows you to understand whether the GPU is to blame for text distortion.

There's also a feature in the developer menu called "Show UI Elements," which can illuminate the boundaries of text fields, which can help you understand whether the text is rendered at all or the field is just blank. If there are boundaries and there is no text, the data is a problem. If there are no boundaries, the layout is a problem.

Special attention should be paid to the option “Scaling animations”: sometimes the text “smears” when the window appears due to low frame rate or animation bug, setting the value “No animation” will help to eliminate this factor.

⚠️ Warning: Do not change the Drawing unless you are sure you are doing something. Incorrect settings can lead to a constant bootloop).

Text Recovery via ADB and Computer

The most powerful tool for working with the system is ADB (Android Debug Bridge) debugging, which allows you to see hidden text that is not displayed on the screen by directly querying the database or logs of the system, and you will need a computer and a Platform-tools package installed to do this.

First, connect your smartphone to your PC with a cable and allow debugging in the developer menu. Then open the command prompt on your computer. To see the latest system messages that may contain hidden error text, use the command:

adb logcat | grep -i "text" | grep -i "error"

This command will filter the log and show only the lines associated with text errors, and if the text is hidden in the SMS database, you can try to upload the database contents directly, if you have root rights, or use backup.

There's also a blind copying method. If the text is visually blurred but the system thinks it's being displayed, you can use accessibility tools or scripts to copy the clipboard content. The adb input shell keyevent 248 command can help copy the highlighted "invisible" text.

For advanced users, the method of reading the database mmssms.db directly through ADB Shell is available if the phone is rooted:

adb shell


su




cat /data/data/com.android.messaging/databases/mmssms.db

However, you can't just output a binary file -- you need a dump in readable form. Use the sqlite3 command inside the shell if it's installed on the system, or copy the file to a PC for analysis with special utilities.

Specifics of working with messages and messengers

Often the problem of “blurred” text is about SMS or popular messengers like Telegram and WhatsApp. In messengers, this can be due to the caching of media files or fonts. Clearing the cache of an application through Settings → Apps → All applications → [Application] → Memory → Clear the cache often solves the problem.

In the standard Messages app from Google or MIUI, text may be hidden because of the spam protection feature. Check the Spam and Locked folder. It's also worth checking if Hidden Chat or Incident Mode is enabled if you use third-party launchers.

If the text in the messages is displayed as a set of characters (Krakozyabr), it is a problem of encoding. Try changing the system language from Russian to English and back again. This action forcibly overwrites the localization configuration files.

For instant messengers, it is important to check the version of the app. Older versions may not work properly with new versions of Android. Update the app through Google Play or the official developer website.

Radical measures: resetting and reflashing

If nothing helps and the text remains unreadable in critical sections, the last option is a complete reset.Be sure to back up your data via Mi Cloud or locally to your computer before doing so, as all data will be deleted.

Reset is done via Settings menu → About phone → Reset → Erase all data. If the menu is unreadable due to text inaccessibility, you can use the key combination to enter Recovery mode: press Volume Up + Power on the phone turned off.

In Recovery mode, you can navigate with volume buttons and select with a power button. Select Wipe Data, which will bring the phone back to factory status, eliminating all the software conflicts that caused the text problem.

⚠️ Note: After resetting the region and language settings, you will need to reset. Make sure you remember the data from your Mi Account to unlock the device.

Prevention of Display Problems

To prevent the problem from recurring in the future, try not to install themes and fonts from unverified sources.The official Xiaomi theme store checks the content, but even there there are errors.When installing third-party launchers, check their compatibility with your version of Android.

Update your system regularly. Xiaomi engineers are constantly releasing patches to fix rendering bugs. Go to Settings → About phone and click on the version icon to check for updates manually.

💡

Timely system updates and the rejection of modification of system fonts is the best prevention of problems with the display of text on Xiaomi.

Also, keep an eye on memory space, and when you fill up more than 90 percent of the storage, the system can start to run unstable, including image artifacts, delete unnecessary files, and use cloud storage.

The use of original accessories and chargers also indirectly affects the stability of memory controllers, which can prevent damage to configuration files.
