How to disable error highlighting on Xiaomi smartphones: the full guide

Are you tired of the annoying red accents on your messages, browser, or Xiaomi notes? This spell check feature in MIUI often works inappropriately — emphasizes foreign words, slang, acronyms, or even properly spelled terms. Worst of all, on some Redmi and Poco models, this line appears even in password fields, preventing you from entering data.

In this article, we will discuss all the working ways to disable underline, from the standard MIUI 14/15 settings to the hidden developer settings. Importantly, the methods differ depending on the firmware version and model (Redmi Note 12, Poco X5, Xiaomi 13T, etc.).

If you've tried to disable spell checker via Settings → Additional → Language and input, but the red line still appears - don't rush to reset your phone. 90% of the time, the problem is solved in 2-3 steps without losing data.

Why Xiaomi is emphasizing the words: 3 main reasons

Before you turn off the function, you should understand which module is responsible for emphasizing in your case, and MIUI may be responsible for this:

• 📱 Gboard or Miui Keyboard system keyboard — highlights errors right while typing. Most commonly found on Redmi and Poco with firmware MIUI 13+.
• 🔍 Google's text checker service, which runs on Chrome, Mi Browser and some apps, highlights when text is sent.
• 📝 Built-in function MIUI "Text Checking – activated in language settings and may conflict with other services.

Interesting fact: on Xiaomi with global firmware (Global) ROM) The emphasis is often more aggressive than in Chinese (China). ROM). This is because in the global versions MIUI Google services are enabled by default, which duplicate the verification.

To pinpoint the culprit, try entering the error text in different apps:

• ✉️ In SMS or Telegram – if stressed, the keyboard is to blame.
• 🌐 In the address bar of the browser – a problem in Google services.
• 📄 In notebook or notes – a system check worked MIUI.

Method 1: Disable the keyboard settings (works 80% of the time)

To start with, the simplest method that most users can use is that if the underline appears during typing (rather than after sending), the keyboard is to blame. MIUI can have two:

1. Gboard (Google Keyboard) is standard for global firmware.
2. Miui Keyboard is a Xiaomi keyboard, found on Chinese versions and some Poco models.

The instructions are a little different for them.

For Gboard (Google Keyboard):

If there is no "Text Check" option, update Gboard to Play Market or reinstall it. On some versions of MIUI 14, this option is hidden, then resetting the keyboard settings will help:

1. Go to Settings → Applications → Application Management → Gboard.
2. Click Warehouse → Clear the data (do not delete the cache!).
3. Reboot the phone.

For the Miui Keyboard:

Xiaomi’s signature keyboard is less flexible, but the underlining in it is turned off as follows:

1. Open Settings → Additional → Language and Enter → Current Keyboard
2. Select Keyboard Settings → Check text.
3. Turn off the slider to check spelling.

Important! On some models (Redmi 10C, Poco M5), the "Text Check" item may be called Autocorrect or Error Correction. If it's not, try Method 2.

💡

If the keyboard starts to slow down after the check is turned off, clear the cache in the application settings, which will eliminate conflicts with system services.

Method 2: Disabling system text check in MIUI

If the underline appears after you enter text (e.g., in messages sent or saved notes), the system verification service is to blame. In MIUI 14/15, it works independently of the keyboard and can conflict with it.

To turn it off:

1. Go to Settings → Additional → Language and Enter → Text Check.
2. Turn off the Spelling Check (or Text Check on English firmware).
3. In the Text Check Services section, select No or Off.

On some firmware (MIUI 13 for POCO), this section may be called Advanced Keyboard Settings or hidden behind the option Additional in the language menu.

Warning: On Xiaomi with China ROM, disabling the system check may cause some applications (e.g. Mi Browser or Notes) to crash, in which case, return the settings back and use Method 3.

Method 3: Disable verification in Google Chrome and other browsers

If the red line only appears in the browser (for example, when searching Google or filling out forms), the Chrome or Mi Browser settings are to blame. These browsers use their own verification module, which is independent of system settings.

For Google Chrome:

1. Open your browser and go to chrome://settings/languages.
2. In the Spelling Check section, turn off the slider Enable spell check.
3. Remove all languages from the list of Languages to check spelling (click on the three dots next to each language).

For Mi Browser:

1. Open the browser, click on the three dots at the bottom → Settings.
2. Go to the Supplementary → Language and input.
3. Turn off Spelling Check and Autocorrection.

If the underline remains after that, clear the browser data:

• 🧹 For Chrome: Settings → Confidentiality → Clear the data → Cache and cookies.
• 🧹 For Mi Browser: Settings → Clear the data → Kesh.

💡

Disabling the browser check does not affect the keyboard and system services; it is a local solution for web pages only.

Method 4: Restricting Google Services (for advanced users)

On Xiaomi Global ROM smartphones, the underline is often associated with the background performance of Google services, even if you have turned off the Settings Checker, which is because Google Play Services is forced to include some features “to improve the user experience.”

To fix this:

1. Go to Settings → Applications → Application Management.
2. Find Google Play Services and open its settings.
3. Press the Battery. → Limit background activity.
4. Also disable AutoRun for this application.

Warning: This can cause delays in receiving push notifications and geolocation problems in some applications (e.g. Google Maps or Uber).

Alternative method (more secure):

1. Open Settings → Accounts and Sync → Google.
2. Disable synchronization for Language and Entering and Personal Data.

Method 5: Disconnect via ADB (for power users)

If none of the previous methods worked, there is a forced shutdown via ADB. This method is suitable for all Xiaomi models (including Redmi Note 12 Pro+, Poco F5, Xiaomi 13 Ultra), but requires a connection to a computer.

You'll need:

• 🖥️ Computer with Windows/Mac/Linux.
• 🔌 USB-cable (preferably original).
• 🛠️ Installed drivers ADB and Fastboot.
• 📱 Included Debugging by USB phone-on.

Step-by-step:

1. Activate Developer Mode: Settings → About Phone → MIUI Version (click 7 times)
2. Enable USB debugging in Settings → Additional → For developers.
3. Connect your phone to your PC and execute: adb shell settings put secure spell_checker_enabled 0
4. To disable autocorrect in Gboard add: adb shell settings put secure spell_checker_enabled_app_specific_settings 0
5. Reboot the phone.

Warning: misuse of ADB can cause system failures, and if you are unsure about your actions, skip this method or contact the XDA Developers or 4PDA forums for help.

What to do if the underline returns after the MIUI update

Many Xiaomi users find that after updating the firmware (MIUI 14 → MIUI 15), the error highlighting is automatically activated again, due to the fact that system applications (Gboard, Miui Keyboard, Google Play Services) reset the settings to standard.

To prevent this from happening:

• 🔄 Turn off automatic app updates in the Play Market for Gboard and Google Play Services.
• 📵 Freeze system applications through ADB (Developer rights required: adb shell pm disable-user --user 0 com.google.android.inputmethod.latin (replaces Gboard with standard keyboard) MIUI)
• 🔧 Use alternative keyboards (such as SwiftKey or Fleksy) that are independent of system settings.

If the update has already occurred and the underline has returned, repeat the steps from Method 1 or 2, but before that:

1. Clear the cache and Gboard/Miui Keyboard data.
2. Turn off the Internet (flight mode) for 5 minutes – this will prevent synchronization of settings with Google servers.
3. Only then turn off spelling check.
