How to Turn Off the Automatic Big Letter on Xiaomi Phone: All Ways

Why Xiaomi Phone Automatically Puts Capital Letters and How to Fix It

You type a message on WhatsApp or Telegram, and your smartphone stubbornly replaces the first letter with a capital letter — even when you don’t need to? This feature, called auto-capitalization, is enabled by default in MIUI firmware and the Gboard/Mi Keyboard. For many users, it’s useful but sometimes intrusive: for example, when entering nicknames, hashtags or technical terms.

In this article, we’ll look at 5 proven ways to disable the automatic big letter on Xiaomi, Redmi, POCO and Black Shark, from keyboard settings to system settings. The instructions are relevant for MIUI 12-14 (including global and Chinese versions), as well as for most models released after 2018. If your phone is older, check the firmware version in Settings → About Phone, as the MIUI 10-11 menu may differ.

Before you start, consider that turning off autocapital letters can affect the automatic spelling correction. If you write often in Russian or English, it may be better to leave the function on, but customize it to suit yourself (more about this in the last section).

Method 1: Disabling autocapital in the Gboard keyboard settings

Most Xiaomi users use Google's Gboard keyboard, which is installed by default on global firmware, to remove the automatic capital letter:

1. Open any field to enter text (for example, in Messages or Notes).
2. Touch the gear badge (⚙️) In the top panel of the keyboard to open its settings.
3. Go to the section Correction of text (or Text correction in English).
4. Find the option Auto-capitalization and turn off the slider.

If you don't have Autocapital letters, update Gboard via Google Play. In older versions, the option could be called Autocapital Writing.

Important! On some Xiaomi models (such as the Redmi Note 10 Pro or POCO X3 Pro) after turning off autocapital letters, the automatic dot addition after the double space may stop working. To return this feature, enable the option of Double Space for the point in the same settings section.

Method 2: Set up a standard Mi Keyboard

If you use the Mi Keyboard, which is installed on Chinese firmware or when you select the system settings, the algorithm will be different, and here the autocapital letters are tied to the smart input function:

1. Go to Settings → Settings → Languages & Input (or Settings → Additional settings → Languages & Input).
2. Select the Mi Keyboard (could be called the Xiaomi Keyboard).
3. Go to the text input settings → Smart input.
4. Turn off the option Auto Capitalization (or Auto Capitalization).

In some versions of the Mi Keyboard, this option is hidden behind additional settings.

• 🔍 Check the Advanced Settings section).
• 🔍 Try changing the keyboard language to English – sometimes the options are duplicated.
• 🔍 Update the keyboard via the Mi App Store (if you use Chinese firmware).

Warning: China ROM MIUI firmware may lose Chinese predicative input after autocaps are turned off. If you use it, it is best to leave the function on and use workarounds (see Method 4).

Method 3: Disable via MIUI system settings (for all keyboards)

If previous methods have failed, try disabling autocapital letters at the system level, which is suitable for all keyboards, but requires access to hidden settings:

1. Open the phone app and dial the combination: ##4636##.
2. In the menu that opens, select Phone Information (or Phone Information).
3. Scroll down to the Other Settings block and find Disable autocapitalization (may be called Disable auto-capitalization).
4. Activate the option and restart the phone.

This method doesn't work on all models, it depends on the MIUI version and regional firmware. If you don't have one, try an alternative way:

Settings → Special features → Keyboard settings → Disable autocapital letters

Attention! ⚠️ Changing hidden settings can lead to unstable keyboard operation. If artifacts appear after the reboot when you type (for example, missing hints or lost layout), reset the keyboard to factory settings in the Settings section. → Annexes → Application management → [Your keyboard] → Warehouse → Clear the data.

Method 4: A workaround for specific applications

If you can’t disable autocapital letters globally (or it interferes with other functions), you can use contextual solutions for individual applications:

There are no workarounds for Instagram, VK and other social networks, such as turning the feature off globally or accepting manual fixes, and in extreme cases, you can copy small letter text from another source (for example, Notepad).

💡

If you often need to type in small letters (like nicknames or commands), create text templates in the Notes app or Google Keep, so you can quickly insert ready-made phrases without auto-corrects.

Method 5: Using third-party keyboards

If standard methods don't help, install an alternative keyboard.The best options for Xiaomi are:

• 📱 SwiftKey - flexible auto-replacement settings, gesture support.
• 📱 Fleksy – minimalist design, advanced options for text.
• 📱 Chroom – Open Source Keyboard (without Advertising).

To set up autocapital letters in SwiftKey:

1. Open the SwiftKey app from the menu.
2. Go to the Input Settings → Auto Replace and Corrections.
3. Turn off Automatic Capital Letter and Two Capital Letter Correction.

Important! After installing the third-party keyboard, remember to make it the default keyboard in the system settings (Settings → Language and Input → Current keyboard). Otherwise, the autocapital letters will still work.

Frequent problems and solutions

Even after you turn off autocaps, Xiaomi users are faced with nuances.

⚠️ Attention, if after the update MIUI The autocap letters turned on again -- it's not a bug, it's a feature of the firmware. Xiaomi resets some keyboard settings when major updates. Check the settings again!

Problem 1: Autocapital letters are disabled, but WhatsApp or SMS still put.

Solution: Clear the cache of the Settings application → Apps → [Messaging Name] → Storage → Clear the cache. If it doesn't help, reinstall the keyboard.

Problem 2: There is no shutdown option on China ROM.

Solution: Install global firmware via Mi Flash Tool or use the Disable Auto Capitalization Magisk module (requires root rights).

Problem 3: After the shutdown, voice messages stopped working.

Solution: Turn autocapital letters back on and use the incognito mode in the keyboard (if any). For example, in Gboard you can hold the microphone icon to temporarily turn off auto-corrects.

💡

If none of these works, check to see if you have a smart input application (such as Grammarly or LanguageTool) that can override keyboard settings.
