How to completely disable T9 on Xiaomi Redmi smartphones: 5 working ways

Auto-replacement and T9 tips on the Xiaomi Redmi keyboard often annoy users: the system stubbornly corrects the right words, offers irrelevant options or slows down typing. This is especially noticeable in MIUI 14/15, where machine learning algorithms have become more aggressive. But disabling the T9 is not so easy - settings are hidden in different menus, and some functions work even after an obvious shutdown.

In this article, we’ll look at all the possible ways to disable auto-replace, from basic settings on Xiaomi’s standard keyboard to hidden Gboard settings and even system tricks through ADB. You’ll learn how to disable app-specific hints, reset the T9 dictionary, and why settings are sometimes reset after an update. Instructions are relevant for all Redmi models (including Redmi Note 12/13, Redmi 10/11) and MIUI versions 12-15.

1.What is T9 and why should it be turned off on Xiaomi

T9 (Text on 9 keys) technology was originally developed for push-button phones to speed up SMS setup. On smartphones, it has evolved into a system of auto-replacement and predictive input, but often works against the user:

• 🔄 Corrects the correct words to the wrong ones (for example, "hello" → "hello").
• 📱 Slows input due to constant prompts, especially on weak Redmi models (e.g. Redmi) 9A).
• 🔍 Highlights “mistakes” in proper names, slang, or professional terms.
• 📊 Collects data about your dictionary (even if personalization is disabled).

On Xiaomi, the problem is compounded by the fact that MIUI uses its own AI-integrated keyboard, which analyzes not only the text you enter, but also the context (for example, in messengers, prompts differ from search queries), which leads to the fact that even after turning off auto-replacements in keyboard settings, prompts can appear in some applications.

⚠️ Note: On Redmi models with MIUI For the global market (e.g. Redmi Note 12 Pro)+ 5G) and Chinese firmware settings T9 In the Chinese version, some parameters are hidden without editing permission.

2. Method 1: Disable the T9 in the standard Xiaomi keyboard

If you use a native MIUI keyboard (called the Xiaomi Keyboard or the Mi Keyboard), follow this instruction:

1. Open any field to enter text (for example, in Messages or Notes).
2. Touch the badge. ⚙️ (gears) on the keyboard to open the settings.
3. Go to the Text Input section → Auto-replacement.
4. Turn off the sliders: 🔘 Auto-replacement (correction of typos) 🔘 Prediction of text (tips over keys) 🔘 Personalized tips (analysis of your messages)

User's dictionary

Clear the data

After these steps, the auto-replacement should disappear, but there is a caveat: MIUI can reset settings after an update or reboot. To consolidate the result, follow the additional step:

If the prompts still appear, your Redmi has a Gboard or a third-party keyboard installed.

3. Method 2: Configure Gboard (Google keyboard)

Gboard is a popular alternative to the standard keyboard on Xiaomi, but its T9 settings are even more confusing.

1. Open Settings → System → Language and input → Virtual Keyboard → Gboard.
2. Select Text Correction and Disable: 🔘 Auto-replacement 🔘 Showing clues 🔘 Dynamic Emoji Offering (if not necessary)

Gboard

Dictionary → Text Input Dictionary → Clear the data

Settings → Applications → Gboard → Storage → Clear data

Important: After the data is cleaned, Gboard can temporarily run slower, which is normal, and in 1-2 days, the speed will recover.

Method 3: Disabling T9 for individual applications

Sometimes auto-replacement is needed in messengers, but it interferes with the browser or code editor. On Xiaomi, you can configure the keyboard separately for each application:

1. Open the app where you want to turn off T9 (like Chrome or Telegram).
2. Tap the input field, then the icon ⚙️ keyboard.
3. Select Settings for [application name].
4. Turn off Auto Replacement and Tips only for this application.

5. Method 4: Reset keyboard settings via ADB (for experienced)

If standard methods do not help, you can resort to system commands. ADB. It's a radical way to reset all the keyboard settings to the factory. USB-cable.

Instructions:

1. Turn on Developer Mode on Redmi: Go to Settings → About Phone → MIUI Version. Click 7 times in a row on the MIUI Version until the notification appears.

USB debugging

Settings → Additional → For Developers

ADB

adb shell pm clear com.android.inputmethod.latin


adb shell pm clear com.miui.mint

For Gboard:

adb shell pm clear com.google.android.inputmethod.latin

⚠️ Note: pm clear commands will delete all keyboard data, including saved words and theme settings. Once executed, you will have to reconfigure the layout and languages.

If you are not sure about your actions, it is better to use safer methods (1-3). ADB-Teams are recommended only for advanced users.

💡

Before using ADB, back up your keyboard settings via Settings → System → Backup. This will help you quickly recover data if something goes wrong.

Method 5: Install an alternative keyboard without a T9

If neither of these methods worked, consider installing a keyboard that doesn’t initially have aggressive auto-replacement.The best options for Xiaomi Redmi are:

• 📱 AnySoftKeyboard – open source, minimalist design, no forced auto-replacement.
• 🔍 Hacker’s Keyboard – Full-size keyboard (like on PC) perfect for programmers.
• 🎨 Simple Keyboard – no analytics and cloud dictionaries, supports gestures.

To install an alternative keyboard:

1. Download the app from Google Play.
2. Go to Settings → System → Language and input → Virtual keyboard.
3. Activate the new keyboard and set it by default.
4. In the new keyboard settings, disable all options related to auto-replace and prediction.

The advantage of this method is full control of input. The disadvantage is that some keyboards (for example, Hacker’s Keyboard) take up more space on the screen, which is inconvenient on compact Redmi models (for example, Redmi 10C).

7.Why T9 can turn on again and how to avoid it

Many Xiaomi Redmi users are faced with the fact that auto-replacement is turned on after:

• 🔄 Updates MIUI (Especially when you switch to a new version, such as MIUI 14-15).
• 📱 Install updates for the keyboard (Gboard or Mi Keyboard).
• 🔧 Resetting phone settings to factory.
• 📲 Reinstalling apps (such as WhatsApp or Telegram).

To prevent automatic activation of T9:

1. Turn off auto-update for the keyboard in Google Play.
2. After updating MIUI, check the keyboard settings immediately.
3. Use an ad blocker (such as AdGuard) to prevent resets due to system notifications.
4. Create a backup of keyboard settings through Settings → System → Backup.

8. Frequent errors when disabling T9 on Xiaomi

Many users make the same mistakes that keep auto-replacement from turning off.

Another common problem is keyboard conflict, where if Redmi has multiple keyboards (like Gboard and standard), the system can switch between them arbitrarily, resetting settings, to avoid this:

1. Leave only one keyboard (remove or disable the rest in Settings → Apps).
2. Set the selected keyboard by default.

💡

If the T9 still works after all the manipulations, check if the Smart Input function is enabled in the MIUI settings (Settings → Special Options → Smart Input).
