How to completely disable T9 on Xiaomi Redmi 9A: all ways to MIUI

Auto-replacement of the T9 on Xiaomi Redmi 9A smartphones is often a source of annoyance: instead of the right words, the system substitutes ridiculous options, and error correction turns into a fight against the algorithm. This is especially noticeable when typing short messages, addresses or specialized terminology, where the MIUI keyboard ignores the user vocabulary in favor of “smart” guesses. In this article, we will analyze all the current ways to disable the T9 – from standard settings to hidden functions and technical solutions for advanced users.

It's important to understand that Redmi 9A is based on MIUI, Xiaomi's proprietary shell, where keyboard settings may vary depending on the firmware version (12, 13 or 14). We tested all the methods on current 2026 builds and highlighted the ones that are guaranteed to work. If you're tired of the phone "guessing" words worse than you remember them, read on.

Why is the T9 not working properly on Xiaomi?

The problem with auto-replacement on the Redmi 9A lies in three key factors:

🔄 Algorithms MIUI: The Mi Keyboard uses a cloud-based wordbase that is updated without the user's knowledge, which means that even if you add a word to the dictionary, it may disappear after updating.
📱 Iron Limitations: Redmi 9A Powered by MediaTek Helio processor G25 It's a very efficient system, and it uses resources very efficiently, so the background processing of text sometimes slows down or crashes.
🌍 Localization: In Russian firmware, there are often errors in the translation of the interface, because of which the keyboard settings can be duplicated or hidden in non-obvious menus.

Fun fact: In MIUI 12 and below, the T9 shutdown worked steadily, but since MIUI 13, Xiaomi has added a “smart correction” that automatically enables auto-replacement to “improve accuracy,” a decision that has caused a wave of complaints as users have lost control of input.

I don't know.

Method 1: Standard T9 disabling in MIUI settings

Let’s start with the simplest method that works on most Xiaomi devices without any additional manipulation.

Open the Settings app (the gear icon on the home screen).
Go to the section Additional → Language and input.
Slip on the current keyboard (usually the Mi Keyboard).
Select the keyboard settings.
Turn off the sliders: 🔘 Auto-replacement (T9) 🔘 Automatic space-space arrangement 🔘 Prediction of text

If auto-replacement still works after this, your version of MIUI uses "deep integration" with cloud services, in which case only completely disabling dictionary synchronization will help:

☑️ Preparation for shutdown T9

Check out the MIUI version (Settings → About the phone)Make a backup copy of the dictionary (keyboard settings → Backup)Turn off mobile internet during settings

Done: 0 / 3

Settings → Google Accounts → Synchronization → Disable “Dictionary Synchronization”

⚠️ Note: Some of the Redmi firmware 9A The auto-replacement option can be called Error Correction or Smart Entering. If you don't find the right setting, use the settings search (the magnifier icon in the upper right corner).

Method 2: Reset keyboard settings to factory

If the standard shutdown didn't work, it could be a clogged user dictionary or a setting conflict, and a complete reset would help:

Open Settings → Applications → Application Management.
Find the Mi Keyboard in the list and tap it.
Select Warehouse. → Clear the data.
Confirm the action (this will delete all saved words and settings).

Once reset, the keyboard will return to factory settings. Now re-disable the T9 as instructed in Method 1. This method is effective in 80% of cases, but has a side effect: you will have to retrain the keyboard with your words.

What if the keyboard became slower after resetting?

It's temporary. It reconfigures the cache to suit your type of typing, and in 1-2 days, the speed will return to normal, and you can speed up the process by turning off the key animation in the keyboard settings.

Problem.	Reason.	Decision
T9 turns on itself after restarting	MiUI Daemon's work is failing	Disable auto-update keyboard in Settings → About phone → Software update
User words are not saved	Dictionary vault is occupied (limit of 500 words)	Clear the dictionary in Keyboard Settings → User Dictionary
The keyboard brakes when the T9 is off	Conflict with MIUI Optimizer	Add keyboard to exceptions (Settings → Battery → Optimization)

Method 3: Install an alternative keyboard (Gboard, SwiftKey)

If the struggle with the native keyboard Xiaomi does not bring results, the logical solution will be to switch to third-party software. 9A:

⌨️ Gboard (Google): Lightweight, with flexible auto-replacement settings and gesture support. minus - requires Google services, which on some firmware MIUI work irregularly.
⚡ SwiftKey (Microsoft): Smart prediction, but more resource-intensive, suitable for active social media users.
🔒 AnySoftKeyboard: Open source, full control of the T9. Ideal for technical professionals.

Installation instructions:

Download the keyboard from Google Play or APKMirror (if Play Market is not available).
Install the application and open it.
In the keyboard settings, disable all auto-replacement settings: 🔘 Autocorrection 🔘 Showing clues 🔘 Dynamic prediction

Settings → Language and input → Current keyboard

💡

Before installing a third-party keyboard, check if it supports your primary input language. For example, Gboard has full support for Russian, and some niche keyboards may only offer English layout.

Method 4: Disable T9 via ADB (for advanced users)

If the software methods don't work, the radical solution is to disable auto-replacement at the system level with the help of ADB (Android Debug Bridge), which requires connecting the phone to a computer and basic command line knowledge.

Advantages of the method:

🔧 Guaranteed shutdown T9 LA-level.
🔒 Save settings after updates MIUI.
📱 It even works on custom firmware.

💡

ADB-Commands change system settings that are not reset after updates MIUI. It's the only way to permanently shut down. T9 rootless.

Method 5: Manual editing of system files (Root required)

For users with unlocked bootloader and SuperSU/Magisk rights, the most radical method is editing keyboard configuration files, which is only suitable if:

🔓 You have a Root access.
🛠️ You are ready for possible failures (NANDroid backup is recommended).
📁 You can work with file managers like Root Explorer.

Instructions:

Install a file manager with Root support (such as FX File Explorer).
Cross the path: /data/data/com.miui.miuikeyboard/shared_prefs/
Find the settings.xml file and open it in the text editor.
Add or change the following lines: <boolean name="key_spell_checker_enabled" value="false" /> <boolean name="key_text_show_suggestions" value="false" /> <boolean name="key_auto_correction_enabled" value="false" />
Save the file and restart the phone.

This method gives you 100% control over auto-replacement, but requires caution, and an error in editing system files can lead to a bootloop.
