How to turn off capital letters on Xiaomi Redmi Note 9

Xiaomi smartphone owners often face the situation where, after entering a sentence, the keyboard automatically activates Caps Lock mode, and the next text is entered exclusively in capital letters.This is not only annoying, but can lead to errors when typing passwords or entering commands sensitive to the case. On the popular Redmi Note 9 model, running on the MIUI shell, this feature is enabled by default for convenience, but many users prefer to control the size of letters manually.

Solving this problem requires intervention in the settings of the virtual keyboard, since the system limitations of Android do not allow you to simply “turn off” Caps Lock with a single button at the hardware level. In most cases, Xiaomi devices have a standard Gboard from Google or their own development MIUI Keyboard. The algorithm of actions will vary slightly depending on what type of text input software is used on your device.

In this guide, we will take a look at all possible ways to deactivate forced register translation, eliminate random key locks, and set up automatic text correction for you, learn to distinguish between system bugs and intentional settings, and learn how to reset input parameters if standard methods do not help return normal printing mode.

Determination of the current keyboard and primary diagnosis

Before you start reconfiguring, you need to accurately identify the active application for text input. Redmi Note 9 can run different engines, and the settings for each of them are in different parts of the system, most often users deal with the standard Gboard keyboard, which is preinstalled on global versions of firmware, or MIUI Keyboard in Chinese builds.

To check the current input tool, open any application that requires typing, such as Notes or Messages. Tap the input box to make the on-screen keyboard appear. Notice the top bar or gear settings: it often shows the name or logo of the active application. If you see the Google logo, then Gboard is used.

⚠️ Note: If you have recently installed third-party keyboards from the Play Market, they may conflict with system settings MIUI. In this case, it is better to temporarily disable third-party input applications to check if the problem with capital letters persists.

Understanding which software handles your clicks is critical, because the path to the right switch will be different, and in some cases, the problem may not be with the settings of the keyboard itself, but with sticking a virtual Shift or Caps Lock button, which requires a separate approach to diagnosis.

Configure the automatic register in Gboard

The Gboard keyboard is the standard for most Android devices, including the Redmi Note 9. It has a feature that automatically translates the first letter of a new sentence to the uppercase. While this is convenient for normal correspondence, in some scenarios, such as when entering nicknames or codes, this becomes an obstacle.

To control this behavior, you need to log into the keyboard settings menu. Press and hold the comma key or the gear icon on the top of the keyboard to open the menu. Next, select Settings and go to Text Set, which hides the main parameters that affect the character register.

You have to find an option called Auto-Capital or Auto-Put Capital. Disabling this slider will stop automatically translating the first letter after the dot, but remember that you can't completely remove the ability to enter capital letters, because that's the basic function of any layout.

• 🔘 Open Gboard settings through the gear on the keyboard.
• 🔘 Go to the "Settings" section» → «Type of text».
• 🔘 Find the Auto-Capital Switch and Deactivate It.
• 🔘 Check the Text Correction section for aggressive auto-replacements.

Gboard also has a feature called "Show the hintbar," which can sometimes get in the way if you accidentally hit the register switching area, and by turning off the extra interface elements, you'll reduce the chance of Caps Lock being accidentally activated during a quick one-hand print.

Register management on the MIUI keyboard

Owners of the Redmi Note 9 with global firmware sometimes use the native MIUI keyboard, which has its own interface and logic. Unlike Gboard, settings can be more deeply integrated into the system, but there are fewer customization options. The interface of settings can vary depending on the version of MIUI (12, 13 or 14).

To access the settings, click on the settings icon (usually a gear or four squares) on the keyboard toolbar. In the menu that opens, select "Input settings" or "Language and Input." Here you need to look for items related to capitalization or automatic fixing. In some versions of the shell, this feature is called "Automatic capital letter".

If standard methods fail to disable intrusive uppercase translation, you can try resetting the keyboard to factory settings, which will remove saved words and personalization, but return the original state of the input system, which often helps with software failures.

It's worth noting that recent MIUI updates have included a Smart Register feature that analyzes the context of a message, so if you type your own name or the beginning of a sentence, the system will decide which letter to capitalize, and turning it off may require a deeper dive into the special features menu.

Solving the problem of sticking virtual buttons

Sometimes the problem with constantly capitalizing on the Redmi Note 9 is not software, but physical or touchscreen. Smartphone screens are sensitive to the slightest touch, and if the Shift or Caps Lock key area is damaged, contaminated or has a software calibration defect, the phone may "think" that the button is pinched.

The first step to diagnose is to visually inspect the screen and clean it. Fat spots, water drops or dust in the bottom line of the keyboard can create false touches. Wipe the screen with a soft cloth and check if the problem has gone away. It is also worth removing the protective glass if it has a crack in the area of the function keys.

If physical cleaning didn't work, try calibrating the sensor. There's a hidden engineering menu on Xiaomi available through code ##6484#. In this menu, you can run the Touchpanel test and check if the tap screen in the problem area registers without you. If the sensor "phonets" in the area of the Caps Lock button, this will confirm the hardware nature of the problem.

⚠️ Warning: Do not use aggressive chemicals to clean the Redmi Note 9 screen.This can damage the oleophobic coating and aggravate tactile sensitivity problems, leading to even more frequent false positives.

In rare cases, sticking can be caused by overheating of the processor or system, when the touchscreen begins to behave incorrectly. If the problem occurs only after a long game or video, let the device cool. Overheating of components can affect the operation of the power controller and the sensor.

💡

Try changing the keyboard theme to contrast, and sometimes changing the location and color of the buttons helps the user to make fewer mistakes and not accidentally hit the register button.

Resetting keyboard settings and cleaning the cache

When software settings are down or errors have accumulated in the input application, the most effective way to solve it is a complete reset. On Redmi Note 9, this is done through the application menu system, which eliminates conflicts that arose after updating the firmware or installing new fonts.

You need to go to the Settings menu of your smartphone, then select the Apps section and find All Apps. In the list, find your keyboard (like Gboard). Click on it, select Memory, and then Clear Cache and Clear All Data, which will return the keyboard to a store-like state.

Settings → Applications → All applications → Gboard → Memory → Clean

Once cleaned, the keyboard will restart and you will have to reconfigure the language and preferences, but this often solves the problem of the “glutty” Caps Lock, which could have been caused by a corrupt configuration file. If the problem recurs after the reset, it may be because the version of the app is incompatible with your version of Android.

• 🗑️ Go to the system application settings.
• 🗑️ Find an active keyboard in the list.
• 🗑️ Perform cache and data cleanup.
• 🗑️ Reboot your smartphone to apply changes.

💡

Completely cleaning the keyboard application data is the most radical, but often the only way to fix program input errors that are not solved by conventional settings.

Using third-party keyboards as an alternative

If MIUI and Gboard are not the standard tools to achieve the desired keyboard behavior, there is always the option of installing an alternative solution. Google Play Store offers dozens of keyboards where register management is implemented more flexibly and understandable for the user.

Popular alternatives like Microsoft SwiftKey or Yandex Keyboard have their own algorithms for predicting and controlling capital letters. They often allow you to fine-tune the sensitivity of the Shift button or even disable the automatic capitalization in advanced settings. Installing a third-party keyboard on the Redmi Note 9 takes a couple of minutes.

Once you install the new application, the system will ask you to allow you to enter text and activate the new layout, and remember to choose it as the main layout for the language and input settings, which will allow you to completely ignore the limitations of the standard Xiaomi keyboard.
