How to turn on T9 on Xiaomi Redmi: 3 working ways for MIUI and third-party keyboards

Are you tired of manually typing every word in messages and your smartphone stubbornly ignores the hints? The T9 (or auto-additional text) feature should make typing easier, but on Xiaomi Redmi it is sometimes disabled by default or knocked off after updates. In this article, we will discuss why auto-replacement disappears, how to return it in the standard MIUI keyboard, and what to do if you use the Gboard or other alternatives.

The problem is relevant for all Redmi models, from the budget Redmi 9A/10A to the flagship Redmi K60 Pro. Most often, users are faced with the fact that the T9 suddenly stops working after resetting, installing custom firmware or even trivial cleaning of the keyboard cache. We tested the solutions on MIUI 12.5-14 and identified three universal methods that will help in 95% of cases.

What is the T9 and why it might not work for the Xiaomi Redmi

T9 (Text on 9 keys) was originally developed for push-button phones, but today it is the generic name for auto-extension systems.

• 🔹 Built-in dictionary – the database of frequently used words, which is replenished by the user himself.
• 🔹 Artificial intelligence – analyzes the context of the sentence (in modern keyboards).
• 🔹 Cloud services – sync dictionary through Google or Mi Account.

On Xiaomi Redmi T9 can be turned off for several reasons:

• 📱 Reset keyboard settings - after updating MIUI or clean up the application data.
• 🔄 Conflict of language packages – if several layouts are installed (for example, Russian) + English).
• 🚫 Limitations on energy conservation — MIUI aggressively optimises background processes, including keyboard learning.
• 🔒 Lack of rights – cloud synchronization requires account and Internet access.

⚠️ Note: If you use Redmi with global firmware (e.g. Redmi Note 12 Global), check the region in settings. In some countries, the default auto-addition is disabled due to legal restrictions on data collection.

Before you get to the settings, make sure that the problem is in the T9, not the keyboard itself. Try typo wording — if the hints don't appear even after a pause, then the function is really disabled.

Method 1: Enabling T9 in a standard MIUI keyboard

The standard MIUI keyboard (aka Mi Keyboard) has hidden auto-addition settings to find them:

1. Open any text field (for example, in Messages or Notes).
2. Touch the gear badge (⚙️) on the keyboard panel to open its settings.
3. Go to the Text Input section → Auto-replacement.

In this menu, you need to activate the following options:

• 🔘 Showing hints – includes pop-up word variants.
• 🔘 Auto-replacement – Corrects typos automatically.
• 🔘 Input training – allows the keyboard to remember your frequently used words.
• 🔘 Synchronize the dictionary – if you are logged in to Mi Account.

If Auto Replace is not on the menu, your version of MIUI is using a stripped-down keyboard.

1. Go to Settings → Applications → Application Management.
2. Find the MIUI Keyboard and select Warehouse → Clear the cache.
3. Restart your phone – sometimes it brings back hidden options.

⚠️ Note: Redmi with firmware for the Chinese market (China) ROM) The solution may not be Russian in the auto-expansion, so you can either install Gboard or change the region in your phone settings.

Method 2: Configure T9 in Gboard (keyboard from Google)

Many Xiaomi Redmi users prefer the Gboard because of its more accurate auto-complement and gesture support.To enable the T9 in this keyboard:

1. Install Gboard from Google Play if you haven’t already.
2. Activate it in settings: Settings → System → Language and input → Virtual keyboard.
3. Open any text field, tap the G icon on the keyboard bar, and select Settings → Text Correction.

In this section, insert:

• 🔘 Showing hints - to display variants of words.
• 🔘 Auto Replacement – for automatic correction of typos.
• 🔘 Dynamic learning – to make the keyboard adapt to your writing style.
• 🔘 Sync the dictionary – if you want to save words in your Google account.

For more accurate work of T9 in Gboard:

1. Go to Settings → Dictionary → Personal Dictionary.
2. Add frequently used words or slang that are not in the standard dictionary.
3. Enable the option Contextual prompts (in the section Correct text) so that the keyboard takes into account the subject of the message.

Important: If the T9 prompts appear late after setting up in Gboard, check if the keyboard is added to the list of optimized applications in MIUI. To do this, go to Settings → Battery → Battery → Battery Optimization and exclude Gboard from automatic optimization.

💡

If the prompts in Gboard are too intrusive, reduce their transparency in the settings: Topics → Transparency of the prompts.

Method 3: Reset and reinstall the keyboard

If previous methods didn't work, it's possible that the keyboard files are corrupted, and a complete reset would help:

For the standard MIUI keyboard:

1. Go to Settings → Applications → Application Management → MIUI Keyboard.
2. Click Warehouse → Clear the data (this will delete all saved words!).
3. Reboot your phone and reconfigure the auto-addition as described in Method 1.

For Gboard:

1. Open Settings → Applications → Gboard → Storage.
2. Click Clear the cache and Clear the data.
3. After the reboot, log in to your Google account to restore your vocabulary from the cloud.

If the problem persists, try reinstalling the keyboard:

• 📲 For Gboard: Remove the app and install it from Google Play.
• 📲 For the standard keyboard: update MIUI Up to the latest version or install Gboard as the primary version.

⚠️ Note: Some Redmi models (e.g. Redmi) 8A or Redmi 9C) The standard keyboard does not support cloud-based dictionary synchronization, and in this case the only solution is to switch to Gboard or SwiftKey.

If you want maximum auto-completion accuracy, Gboard or SwiftKey will be the best choice, and the standard MIUI keyboard will be suitable for those who prefer minimalism and do not want to install third-party applications.

Additional Tips for Better T9 Performance

Even after enabling the auto-addition, his job may not be perfect. Here are some life hacks for Xiaomi Redmi:

• 🔄 Update the dictionary: Go to Settings in Gboard → Dictionary → Update the dictionary. MIUI Keyboard update your phone firmware.
• 📱 Turn off power saving: Add the keyboard to the exception list in Settings → Battery → Optimizing the battery.
• 🌐 Check the system language: If the phone has English as its primary language, Russian hints may not work. Add Russian to Settings → Additionally. → Language and input.
• 🔍 Use Incognito Mode: Gboard has an Incognito Mode option (in settings) that disables keyboard learning for specific applications (useful for banking applications).

If you often write in multiple languages, set up an instant transition between layouts:

• In MIUI Keyboard: Settings → Language and input → Space for changing the language.
• In Gboard: Settings → layouts → Drag the space for changing the language.

For Redmi root-right users, there is a radical solution: installing a modified keyboard through Magisk.For example, the MIUI Keyboard Mod module adds advanced T9 settings, but this is risky for system stability.

💡

If the auto-addition doesn’t work properly, first check if the phone is power-saving mode enabled – it often blocks the background processes of the keyboard.

Frequent Mistakes and How to Avoid Them

Many Xiaomi Redmi users make the same mistakes when setting up the T9.

• 🚫 Ignoring updates: An outdated version of the keyboard or MIUI It may not support modern auto-completion algorithms. Always update the software.
• 🚫 Clearing Data Without Backup: Before resetting your keyboard, save your dictionary to the cloud (if you have such an option).
• 🚫 Use of pirate firmware: unofficial versions MIUI frequently break system applications, including keyboard.
• 🚫 Internet Shutdown: Cloud-based prompts (such as Gboard) require access to the network.

Another typical problem is the conflict of keyboards, and if you have multiple layouts (e.g. MIUI Keyboard + Gboard), they can interfere with each other.

1. Go to Settings → System → Language and input → Virtual keyboard.
2. Turn off unnecessary keyboards, leaving only one main one.

If the T9 doesn’t work after all the manipulations, check if the phone has ad blocking apps or VPNs installed, some of which (like AdGuard or Blokada) can block keyboard access to Google or Xiaomi servers, causing auto-completion failures.
