On devices with the MIUI shell (versions 12-14), the setting is hidden in an unobvious way, and in some firmware, its location has changed after updates.

Today, we’ll learn how to turn on the T9 on any Xiaomi phone, from the budget Redmi Note 12 to the flagship Xiaomi 14 Ultra. Step-by-step instructions will be suitable for the standard MIUI Keyboard, as well as for alternative keyboards like Gboard or SwiftKey if you use them, and pay special attention to typical errors that may cause prompts to fail even after activation of the function.

At the end of the article, you'll find answers to a lot of questions: why the T9 suddenly disappeared, how to reset the dictionary of clues, and whether you can transfer user words when you change your phone.

What is T9 and why is it needed for Xiaomi?

T9 technology (Text on 9 keys) was originally developed for button phones, where each digital key was responsible for several letters. Today, T9 is understood as any predictive input, where the keyboard analyzes your messages and offers continuation of words or entire phrases. On Xiaomi smartphones, this feature is integrated into the MIUI Keyboard system keyboard and includes:

Unlike simple autocomplete, the T9 on Xiaomi takes into account the context of correspondence: for example, if you often write to a colleague “Report is ready”, the system will suggest this phrase when you type the first letters. The algorithm also adapts to slang, jargon, and even typos – if you constantly write “priv” instead of “hello”, the keyboard will adapt to your style.

According to Xiaomi, users with the T9 enabled save up to 40% of their time on typing. However, many people turn off the function due to too intrusive prompts or errors in the dictionary. Fortunately, MIUI Keyboard allows you to fine-tune the sensitivity of the algorithm, as we will discuss in one of the following sections.

• 🔍 Word hints – options for continuation when entering 2-3 letters.
• 📝 Auto-replacement – correcting typos (e.g., “hailing» → «salute»).
• 💬 Contextual phrases – sentences of whole expressions based on the history of correspondence.
• 🌐 Multilingualism – Support for prompts in multiple languages at the same time.

Where is the T9 setting on Xiaomi: the way in the menu

Depending on the MIUI version and the phone model (Redmi, Poco, Black Shark), the path to T9 settings may be different. Below are the current options for MIUI 12–14 firmware (2022–2026). If your phone is upgraded to HyperOS, the instruction will also fit — the difference is only in the menu design.

Standard path for most devices: Settings → Additional → Language and input → Current keyboard (MIUI Keyboard) → Settings → Text input → Prediction of text.

On some models (such as the Xiaomi 13T or Redmi Note 11 Pro+), the text prediction option may be called Smart Input or T9 and Auto Replace. If you don't find the section, search for settings (the magnifier icon in the upper right corner) and type in "keyboard hints."

Open the “Settings” of the phone

Go to the section "Language and input"

Select an active keyboard (MIUI Keyboard)

Find the item "predicting text" or "Smart input"

-->

If you use an alternative keyboard (like Gboard), the path will be different: Gboard Settings → Text Input → Show hints. Note that third-party keyboards may call the T9 feature “Vorative Tip” or “Dynamic Input.”

⚠️ Attention: On phones with MIUI Global (European firmware) and MIUI China (Chinese) menu item names may vary. If you have a Chinese version of the software, turn on the translation of system labels in Settings → Additionally. → Special facilities → Translation of system texts.

Customization of the dictionary and personalization of tips

By default, MIUI Keyboard uses a common vocabulary that includes the most common words and phrases, but you can expand it with your own terms, slang or professional vocabulary, which is especially useful if you often write on specific topics (such as medical terms or gaming jargon).

What to do if the T9 does not work after switching on

Sometimes the clues don't appear even after you activate all the settings, and here are the most common reasons and ways to eliminate them:

Tips for Effective Use of T9 on Xiaomi

To make the prediction input work as accurately as possible, follow these recommendations:

1. Teach the keyboard. For the first 1-2 weeks, actively use the hints — the more often you choose the proposed words, the more accurate the algorithm becomes. If the keyboard offers the wrong option, do not ignore it, but enter the word fully so that the system remembers the correct option.

2. Set language priority. If you write in multiple languages, prioritize keyboard settings → Languages → Drag languages in the right order. For example, if Russian is used more than English, put it first.

3. Use gestures. The MIUI Keyboard supports gestures for quick input:

• 👆 Swipe up the space key to hide/show hints.
• 👉 Swipe right on the delete key to erase the whole word.
• 👈 Swipe left on the space key to insert the last word deleted.

4. Sync the dictionary. If you have multiple Xiaomi devices, enable dictionary sync via your Mi Account: Settings → Xiaomi Account → Sync → Keyboard data.

💡

The longer you use T9, the more it fits your writing style. Don't turn it off in the early days, give the algorithm 1-2 weeks to learn.
