Owners of Xiaomi, Redmi and Poco smartphones often face a situation where the virtual keyboard suddenly starts typing only in capital letters, this can occur due to accidental pressing, operating system failure or language settings, the problem causes significant discomfort when typing text messages, especially if you need to urgently respond to an important notification.
In most cases, the solution is within one or two touches of the screen. However, if standard methods do not work, you may need to have a deeper system setup or check third-party applications. In this article, we will discuss all possible ways to return to normal input mode and prevent a recurrence of the situation in the future.
It's worth noting that the MIUI and HyperOS interfaces have their own features that distinguish it from pure Android. So the paths to settings may vary slightly depending on the firmware version and model of your device. We'll look at universal methods that are suitable for most of the modern gadgets of the Chinese brand.
Main reasons for register switching
Before you start fixing a malfunction, you need to understand the nature of the malfunction, and most often, the problem is the user's inattention, and there's a special register switch on the keyboard that looks like an up arrow, and one careless touch puts the entire input into Caps Lock mode.
Another common reason is the aggressive operation of autocorrection algorithms, which is that the system tries to guess the beginning of a sentence or its own name by automatically replacing lowercase letters with capital letters, and this behavior can and should be corrected through language settings.
⚠️ Note: If the keyboard has got stuck in capital letters mode after installing a new application, try to remove the recently downloaded software.
Also, consider software failure: In rare cases, the process responsible for typing text can “hang” in a certain state. Rebooting the device or forced stop of keyboard service often helps to reset this temporary glitch.
Different models, such as the Xiaomi Redmi Note 12 or the flagship Xiaomi 14, can use different versions of the shell, which affects the location of the controls. However, the logic of the Gboard or Sogou keyboard (standard for China) remains the same for the entire ecosystem.
Quick switching through the screen buttons
The easiest way to fix this is to use visual interface elements. The standard Shift key has a dual-action logic, a short press changes the register for the next character, and a double press changes the mode.
If you see the arrow on the case change button highlighted or lit bright, you activate the constant capitalization mode. To remove this, just press the button again. The visual indicator should go out, and the keyboard will return to lowercase letters.
Some versions of MIUI firmware have a swipe-over-space function, and swiping left or right on a long bottom key can quickly change the language or layout, sometimes resetting the erroneous register settings.
It's important to distinguish between keyboard behaviors across apps. In messengers like Telegram or WhatsApp, autocapitalization algorithms may work differently than in a standard Messages app, see if the problem is replicated everywhere or in just one program.
Setting up the Gboard keyboard on Xiaomi
Since Gboard is the de facto standard for many Android users, let’s take a look at its settings in detail. To get into the configuration menu, you need to press the comma key or gear icon if it appears on the toolbar.
In the menu that opens, you'll find the section that's responsible for preferences or text settings, and that's where the switches that control the behavior of the first letter and the automatic transition to the uppercase are hidden.
☑️ Checking Gboard settings
Note the "Cover-up" item, which, if activated, will automatically make the first letter of each new sentence capitalize, which is convenient for typing long texts, but annoying when you type in passwords or nicknames.
You can also find the "Show Caps Lock" setting in this section, and if you turn on this option, you'll see a separate top-case lock button on the keyboard, which will eliminate the occasional double taps on Shift.
⚠️ Note: After changing the settings in the Gboard menu, the changes take effect instantly. However, in some system input fields (for example, when searching in settings), the keyboard may not update until the application is reopened.
You can use the "Advanced" menu to fine-tune it, and sometimes you have error-correcting options that can force you to change the letter register if the system thinks you've made a typo.
Managing the standard MIUI keyboard
Devices shipped to the Chinese market or some global versions use Xiaomi’s own development, often based on the Sogou engine.
To access the settings, you need to find a menu icon, which is usually located in the top row of buttons or called by a swipe. In the menu, you should search for the "Input settings" or "Language and input" section.
It is important to check the status of Auto-Corption and Auto-Capitalization functions here. In Chinese firmware versions, these functions can be enabled by default and work more aggressively when trying to correct pinyin or English words.
| Function | Description | Recommended condition |
|---|---|---|
| Auto-capital | Makes the first letter of a sentence large | If you wish, |
| Caps Lock | Upper case fixation | Off. |
| Auto-correction | Word correction on the fly | Included (with caution) |
| Predictive text | Proposal of words | Included. |
If the standard settings don't work, you can try to clear the keyboard data, which will bring it back to factory status by removing the accumulated vocabulary and user preferences.
Remember that the HyperOS firmware update can reset some personalized input settings, so after a major system update, it’s worth checking the keyboard settings again.
Deep cleaning and resetting of input settings
If the problem is software-based and not solved by simple switches, a more radical approach will be needed, and you need to go to the Android system settings via the menu “Advanced Settings” or “Additional”.
In the Language and Entering section, select Keyboard Management, where you can not only disable unnecessary input methods, but also clear their cache. Accumulated temporary files sometimes cause conflicts in the work of system services.
