Owners of Xiaomi, Redmi and POCO smartphones often encounter situations where the capital mode is accidentally activated when you type text, which can be due to the peculiarities of the virtual keyboard or the accidental touch of the screen. The big letter (Caps Lock mode) changes the register of all the text you enter, which annoys users who are used to standard typing.
In this article, we’ll look at how to turn off case locks, adjust keyboard behavior, and prevent accidental switching. You’ll learn about the intricacies of Sogou’s system keyboard and third-party counterparts like Gboard. Understanding these settings will allow you to type faster and error-free.
The main problem is long-press algorithms. Android on the MIUI shell or HyperOS, by default, offers several ways to activate Caps Lock, and we will look at each of them and provide a solution for comfortable use of the device.
Why Xiaomi's keyboard spontaneously turns on Caps Lock
The phenomenon of spontaneously turning on capital letters is often associated with touchscreen sensitivity or press sensitivity settings. When you hold your finger on the Shift key a little longer than you put it, the system regards this as a register lock command. On Xiaomi devices, this behavior is embedded in the logic of the standard keyboard.
In addition, the reason can be installed themes or third-party applications for text input. Some skins change the size of the keys or their activation zone, which leads to frequent input errors. Touch screen can respond to light touches that the user does not even notice.
Another factor is a software failure in the input service, where if the keyboard cache has accumulated in the background, it may not behave properly, and in such cases, resetting the input application settings often solves the problem.
- 🔍 Accidental long-term press on the Shift key activates Caps Lock fix.
- 🎨 Design themes can shift the active button areas, causing errors.
- 📱 Input service software failure requires cleaning the cache or reinstalling updates.
- ⚙️ High screen sensitivity exacerbates false positives problem.
⚠️ Warning: If Caps Lock mode turns on on its own even without your keyboard touch, check the screen for damage or contamination.A sticky screen or cracks can close contacts and send false signals.
Setting up the standard Sogou keyboard on Xiaomi
Most Xiaomi smartphones use the Sogou keyboard as the default system keyboard, and it is in its settings that the basic register management parameters are hidden. To access them, you need to call the keyboard in any input field and click on the settings icon (usually a gear or an "S" icon in the top panel).
You'll find the settings menu for text input or "Input settings." This is where you'll find the switch that activates Caps Lock when you double tap or press long-term, and turning it off will return the Shift key to the standard behavior of switching the register for only one character.
Sogou also has a Smart Caps Lock feature that tries to guess when you need a capital letter (like at the beginning of a sentence). If this feature doesn't work properly, it's also recommended to deactivate it. The settings interface may vary slightly depending on the version of MIUI.
☑️ Sogou setup
After making changes, be sure to test the keyboard in different applications. Sometimes the settings are not applied instantly, but require restarting the active application. Rebooting the smartphone will also help to fix new system parameters.
Register management in Gboard and other keyboards
If you use Google’s Gboard or other alternative keyboards (like SwiftKey), the logic may be different. In Gboard, the default Caps Lock is activated by double-quick tapping on Shift. This behavior can be changed or completely disabled in the app settings.
To do this, go to Settings → System → Language and input and select Gboard. In the Settings section, find the Caps Lock key. Here you can disable the capital letter mode or, conversely, make it the main action of the key. The flexibility of the settings allows you to adapt the keyboard to any type of printing style.
In other keyboards, like Yandex Keyboard or SwiftKey, look for the layout, input, or text correction sections. Often there's a "Block capital letters" option that needs to be put inactive. Third-party applications often have more advanced text prediction algorithms.
Table: Comparison of Caps Lock activation methods
Different keyboards and OS versions use different combinations of actions to enable capital letter mode. Below is a table that helps identify the source of the problem on your device.
| Type of action | Standard (Sogou) | Gboard | SwiftKey |
|---|---|---|---|
| Double tap. | Includes Caps Lock. | Includes Caps Lock. | It's not working. |
| Long press. | Includes Caps Lock. | Includes Caps Lock. | Includes Caps Lock. |
| Single tap | One big letter. | One big letter. | One big letter. |
| Pressing the arrow | Resetting the register | Resetting the register | Resetting the register |
As you can see from the table, double tap is the most common cause of random activation. Knowing this, you can control your typing behavior. Changing your typing habit (avoiding double taps) can solve the problem without digging deep into the settings.
Additional functions and hot keys
The MIUI and HyperOS shells offer additional text-handling tools, such as some versions have a floating keyboard that can have its own register settings. If you use this mode, check its settings separately.
Also worth mentioning is voice input. When you switch to voice input, Caps Lock can be reset or activated depending on the context. Voice commands are sometimes interpreted by the system as capitalized text.
For users working with external keyboards (Bluetooth or USB), it is important to know that the physical Caps Lock key will work regardless of the on-screen keyboard settings, in which case you need to look at the indicators on the keyboard itself or in the Android status bar.
- 🔊 Voice input can automatically start phrases with a capital letter.
- 📐 The floating keyboard has an independent set of settings.
- 🔌 External Bluetooth keyboards ignore screen input settings.
- 🌐 In some language packages, capitalization rules differ.
⚠️ Note: When connecting an external keyboard through OTG Caps Lock indicator can appear in the Android status bar, but not on the keyboard itself if it doesn't have LEDs.
Solving sensor problems and calibration
If the software settings don't work, the problem may lie in the hardware part. The touch layer of the smartphone could be recalibrated. Xiaomi devices have an engineering menu to check and calibrate the touchscreen.
To get into the check menu, open the Phone app and enter the code ##64663## (or ##6484### depending on the model). Select "Touchpanel" or "TP Version." Follow the on-screen instructions to check the response. Calibration will help reset the error areas.
In some cases, resetting all settings to factory settings helps, but this is an extreme measure. Before you do, try simply clearing the keyboard app data in Settings → Apps → All Apps. Cleaning up the data will return the keyboard to factory settings without deleting your phone's personal data.
