Red Emphasis in Xiaomi Notes: How to Remove Forever?

Red wavy underlining in the Notes app on Xiaomi, Redmi or POCO smartphones is a common problem that annoys users. It appears under words that the system thinks are written with error, but often makes mistakes on its own. Unlike classic text editors, where spelling correction is flexible, in the standard Mi Notes app, this process is not always intuitive.

In this article, we’ll look at 5 proven ways to remove red underline from Xiaomi notes, from simple tweaks to radical solutions. You’ll learn why it occurs, how to disable spell checks in whole or in part, and what to do if the problem returns after the update. And a unique method for devices with MIUI 14 and later, which is not described in the official documentation.

Why does the red accent appear in Xiaomi notes?

The red wavy lines under words are the work of the built-in spell checker that is activated by default in Mi Notes, and the system compares the text you typed to the dictionary and highlights the words that:

• 🔴 Absent in the dictionary (for example, jargon, proper names, technical terms).
• 🔴 Written with a typo (missed letter, extra symbol).
• 🔴 Use non-standard layout (for example, English words in the Russian text without changing the language).
• 🔴 Contain grammatical errors (incorrect endings, reconciliation).

But Xiaomi's algorithm is far from perfect. It's often wrong with:

• 📛 Names and surnames (for example, emphasizes "Ivanov" as a mistake).
• 💻 Technical terms (MIUI, HyperOS, Snapdragon).
• 🌍 In Russian language, foreign words (for example, “coffee” or “menu»).
• 📱 Slang and abbreviations ("lol", "kk", "pk»).

Moreover, after MIUI or HyperOS updates, the dictionary may reset and the problem returns, and in some cases, the accent appears even in encrypted notes, making it difficult to work with sensitive information.

Method 1: Disabling spell check in note settings

The most obvious method is to disable the check directly in the Notes app, but not everyone knows where to look for this option, as its location depends on the version of MIUI.

Instructions for MIUI 12-14 and HyperOS:

1. Open the Notes app.
2. Slap the icon «⋮» (three points) in upper right corner.
3. Select the Settings item.
4. Scroll down to the Spelling or Language and Entering section.
5. Turn off the Spelling Check (or Autocorrection) switch.

If there is no such item, try an alternative path:

1. Hold your finger on a word with a red accent.
2. In the menu, select the menu (or ⋮).
3. Slip spell check settings.
4. Turn off the option to show hints.

⚠️ Note: On some firmware (for example, MIUI 13 Global) Spelling check disabling may be reset after the device is restarted. In this case, proceed to Method 3.

Method 2: Adding words to a user dictionary

If you need a spell check, but the red underline appears under the correct words (names, terms, slang), you can add them to the user dictionary, which will eliminate the emphasis without completely disabling the function.

How to add a word to the dictionary:

1. Slap on the underlined word and hold your finger for 1-2 seconds.
2. In the context menu, select Add to the dictionary (or Remember a word).
3. Confirm the action.

For mass word additions (for example, if you are a tech blog or lecture summary):

1. Go to Settings → Additional → Language and input → Virtual keyboard.
2. Select the keyboard you use (Gboard, SwiftKey, or Xiaomi Keyboard).
3. Find the dictionary or user words section.
4. Add words manually or import from the file.

⚠️ Note: If you use the Xiaomi Keyboard, added words may be reset after the update MIUI. It is recommended to make a backup copy of the dictionary through Settings. → Memory. → Backup.

Method 3: Reset the settings of the Notes app

If the red accent doesn't disappear even after you turn off spell check, the problem may be cache or damaged app settings, and resetting will help.

Instructions:

1. Go to Settings → Applications → Application Management.
2. Find "Notes" (com.miui.notes) and tap it.
3. Choose Warehouse.
4. Click Clear Cache and Reset Settings (or Delete Data, but this will delete all notes!).
5. Reboot your smartphone.

After reset, check if the notes are saved. If not, restore them from the backup (Settings → Xiaomi Account → Cloud → Notes).

⚠️ Note: On some devices (Redmi Note 10 Pro, POCO X3 Pro) resetting the application settings may result in the loss of encrypted notes.Be sure to back up through Settings before the procedure → Memory. → Backup → Notes.

Method 4: Use of alternative note-taking applications

If Xiaomi’s standard Notes app continues to emphasize words despite all the manipulation, consider switching to alternative programs that offer more flexible spelling settings and are often better optimized.

Top.-5 Note-taking applications without red underlining:

• 📝 Google Keep – Simple interface, sync with Google account, no intrusive spell check.
• 📒 Microsoft OneNote – Supports formatting, adding images and handwriting without stressing.
• 🔖 Simplenote – minimalist design, no automatic spell check.
• 📌 Evernote is a powerful feature, but spell check is turned off in the settings.
• 🛡️ Cryptee – encrypted notes without surveillance and stress.

To transfer notes from Mi Notes to another app:

1. Export notes to Settings → More → Export (.txt or.zip format).
2. Import the file to the new app through its Import menu.

💡

If you’re afraid of losing data when you switch to another app, test it first on a secondary device or an Android emulator (like BlueStacks).

Method 5: Manual editing of system files (for advanced ones)

This method is only suitable for users with unlocked bootloader and root rights, and allows you to completely disable spell check at the system level, but requires caution.

Instructions:

1. Install a file manager with root support (such as Root Explorer or Solid Explorer).
2. Go to /system/usr/spellchecker/ or (for HyperOS): /vendor/overlay/spellchecker/
3. Find files with the.apk or.xml extension associated with spellchecker.
4. Rename them by adding.bak at the end (e.g. spellchecker.apk → spellchecker.apk.bak).
5. Reset the device.

⚠️ Attention: Incorrect editing of system files can lead to application dye or bootloop ( looped boot:

• Create a full backup through TWRP.
• Check compatibility with your version of MIUI/HyperOS.
• Have a firmware on hand for recovery.

💡

Editing system files is a last resort, 90% of the time the first 4 fixes the problem, and only use this method if you are a skilled user and risk-averse.

Additional advice and answers to questions

If none of these methods helped, check the following points:

• 🔄 Update the Notes app via Play Market or App Gallery.
• 🌐 Check the system language: if it differs from the keyboard language, conflicts may arise.
• 📱 Reset the language settings and enter into Settings → System system → Resetting settings → Resetting application settings.
• 🛠️ Install custom firmware (like Pixel Experience) that doesn’t have a built-in spell check from Xiaomi.

Also, it is worth considering that on some devices (Xiaomi 12T, Redmi K50) red underline may appear due to conflict with Google services, in which case, disabling Google Play Services for the Notes app will help:

1. Go to Settings → Applications → Application Management → Google Play Services.
2. Tap Permits and disable access to Notes.
