Are you tired of the fact that your smartphone automatically replaces the first letter of a sentence with a capital one, even when it is not necessary? This function auto-capital letters (auto-capitalization) is enabled by default on all Androiddevices, but it can be disabled - completely or selectively. The problem is especially relevant for users who often write in an informal style, use Telegram, VK or other instant messengers, where the rules of punctuation are not so strict.

In this article we will look 5 working methodshow to force the keyboard to always write with a small letter - from standard settings to hidden features and third-party applications. You'll learn how to customize AutoCorrect behavior for specific apps (for example, only WhatsApp), why settings sometimes reset after an update, and what to do if the keyboard ignores your changes. All methods have been tested on the latest versions Android 13–15 and popular keyboards: Gboard, Samsung Keyboard, SwiftKey.

We warn you right away: some solutions require manual editing of system files or installing additional software. If you are not ready to experiment, use the first two methods, they are safe and work on 90% of devices.

1. Disabling auto-capitalization in keyboard settings

The easiest method is to deactivate the function directly in the keyboard settings. Most manufacturers (including Google, Samsung, Xiaomi) allow you to do this without root access. The instructions are universal, but the menu paths may vary slightly depending on the firmware.

Here's how to do it on Gboard (standard keyboard for most Android devices):

  1. Open any application with a text field (for example, Notes or Messages).
  2. Tap the icon gear (⚙️) on the keyboard to go to its settings.
  3. Select Text input → AutoCorrect (or Text correction).
  4. Find option Auto-capital letters (may be called Start sentences with a capital letter) and disable it.

For Samsung Keyboard the path will be different:

Settings → General settings → Language and input → Virtual keyboard → Samsung Keyboard → AutoCorrect → Autocaps

A text field is open in the messenger

The gear on the keyboard is pressed

Found the "AutoCorrect" or "Text Correction" section

The "Auto Capitalization" option is set to "Off."

Tested in 2-3 applications (messages, browser, notes)-->

⚠️ Attention: On some devices (for example, Huawei or Realme) the option may be hidden deeper or absent altogether. If you do not find it, proceed to the next method.

2. Using alternative keyboards with your own settings

If the standard keyboard does not provide flexibility, install a third-party one. The best options for controlling auto-capital letters:

  • 🔹 SwiftKey (from Microsoft): allows you to disable auto-capital letters separately for each language.
  • 🔹 Fleksy: has advanced correction settings, including case control.
  • 🔹 AnySoftKeyboard: open source code, maximum customization.
  • 🔹 Chroom: minimalistic keyboard without unnecessary "helpers".

Example setup in SwiftKey:

  1. Install the keyboard from Google Play and activate it in the system settings (Settings → System → Language and input → Virtual keyboard).
  2. Open the application SwiftKey, go to Settings → AutoCorrect and corrections.
  3. Find Auto capital letters and disable it.
  4. For precise settings, tap Advanced parameters and select in which cases capital letters should appear (for example, only after a period).

💡 Useful tip: If you often switch between languages, SwiftKey you can configure auto-capital letters separately for Russian and English. This is convenient if you want to preserve punctuation rules in one language, but not in the other.

3. Editing system files (for advanced users)

If none of the above methods worked, you can intervene in the system settings. This method is suitable for devices with root access or custom firmware (for example, LineageOS). Without root, access to files will be limited.

You will need:

  • 📱 A device with unlocked bootloader rights superuser.
  • 🛠️ File manager with root support (for example, Root Explorer or Solid Explorer).
  • 📝 System backup (in case of errors).

Instructions:

  1. Open the file manager and go to path: 
    /system/usr/keylayout/

    Find the file Generic.kl (or similar for your model).

  2. Copy it to a safe place (for example, to an SD card) in case of recovery.
  3. Open the file in a text editor and find the line: 
    key 115 VOLUME_UP

    Under it, add:

    key 200 CAPS_LOCK

    (this will disable forced case changing).

  4. Save the file, return it back to /system/usr/keylayout/ and reboot the device.

⚠️ Attention: Incorrect editing of system files can lead to to data loss or cyclic reboot devices. If you are not sure of your actions, skip this method.

What to do if after editing the keyboard stops working?

If after changes to the system files the keyboard refuses to appear or enters characters incorrectly, follow these steps:

1. Connect the device to the PC via ADB and return the original file Generic.kl back.

2. If ADB is not available, reset your keyboard via Settings → Applications → Manage applications → [Your keyboard] → Storage → Clear data.

3. As a last resort, perform a factory reset (the data will be lost!).

4. Setting up autochange via ADB (without root)

If you do not have root access, but have access to ADB (Android Debug Bridge), you can disable auto-capital letters via the command line. This method works on most devices with Android 8.0+ and does not require unlocking the bootloader.

You will need:

  • 🖥️ A computer with installed ADB Tools (you can download from the official site Google).
  • 📱 Enabled USB debugging on the smartphone (Settings → About phone → Build number — tap 7 times, then return to Settings → System → For developers → USB debugging).
  • 🔌 USB cable for connection.

Steps:

  1. Connect the phone to the PC and open the command line (or Terminal on macOS/Linux).
  2. Enter the command to check the connection: 
    adb devices

    If the device is displayed, continue.

  3. Run the command to disable auto-capitalization: 
    adb shell settings put secure auto_capitalization 0
  4. Reboot device.

Important: This command only works for the standard Google keyboard (Gboard). Other keyboards (for example, Samsung Keyboard) may require different settings.

5. Reset the keyboard to factory settings

If all the previous methods did not help, try resetting the keyboard. This will return it to the “as after” state. purchases", but will save all your dictionaries and learned words.

Instructions:

  1. Go to Settings → Applications.
  2. Find your keyboard (for example, Gboard or Samsung Keyboard) and tap on it.
  3. Select Storage → Clear cache.
  4. Then click Clear data (this will reset all personal settings, but will not delete dictionaries).
  5. Restart the keyboard and check if the problem remains.

⚠️ Attention: After resetting the data, you will have to do the following again:

  • 🔄 Customize the theme and keyboard layout.
  • 📚 Add custom words to the dictionary.
  • ⚙️ Enable/disable autocorrect and other functions.

Comparison of methods: which method to choose?

To make it easier for you to decide, we have collected the main pros and cons of each method in the table:

Method Difficulty Requires root/ADB Works on all keyboards Risk to the system
Settings keyboard ⭐ (simple) ❌ No ⚠️ Only for supported ❌ No
Third-party keyboard ⭐⭐ (moderate) ❌ No ✅ Yes ❌ No
Editing system files ⭐⭐⭐⭐ (difficult) ✅ Root is required ✅ Yes ⚠️ High
ADB commands ⭐⭐⭐ (medium) ✅ ADB needed ❌ Gboard only ⚠️ Low
Reset keyboard ⭐ (simple) ❌ No ✅ Yes ❌ No

If you don’t want to take risks, start with the first or second method. They cover 80% of cases and do not require technical skills. For experimenters, ADB or editing system files is suitable, but be aware of the possible consequences.

💡

Third-party keyboards (for example, SwiftKey) often offer more options for customizing auto-capital letters than standard solutions from manufacturers.

Frequent problems and their solutions

Even after disabling auto-capital letters users face nuances. Here are the most common situations and ways to fix them:

  • 🔄 Settings are reset after the update: Manufacturers sometimes return the settings to factory settings when updating the firmware. Solution: check your keyboard settings after each update.
  • 📱 Does not work in all applications: Some messengers (for example, Viber) have their own autocorrect rules. Solution: disable auto-capital letters directly in the application settings.
  • ⚡ The keyboard lags after changes: Clear the keyboard cache in the application settings or reinstall it.
  • 🌐 The problem is in one language only: B On multilingual keyboards, autocaps settings may be duplicated for each language. Check them separately.

⚠️ Attention: On devices with Android Go (for example, Nokia 1, Samsung Galaxy J2 Core) keyboard customization options are often limited. In this case, only installing a third-party keyboard will help.

💡

If you often write code or commands in the terminal, create a separate keyboard profile with autocorrect and autocapitalization disabled. This will save time on editing the case.

Is it possible to disable auto-capital letters only for a specific application?

Yes, but not in all keyboards. For example, in SwiftKey you can create a separate profile for each application with unique settings. In Gboard there is no such function - the changes are applied globally.

Why, after turning off auto-capital letters, does the first letter still become capitalized?

You probably have the function enabled "AutoCorrect" or "Grammar check" v keyboard settings. Disable them or check whether the settings of a specific messenger do not overlap (for example, Telegram has its own formatting rules).

Will the ADB method work on Xiaomi/Redmi?

On most devices Xiaomi with MIUI ADB commands are executed without problems, but additional permission may be required in the developer settings (USB Debugging (Security Options)). If the command does not work, try adding the flag --user 0:

adb shell settings put secure auto_capitalization 0 --user 0
How to get auto-capital letters back?

Simply repeat the steps from the selected method in reverse order:

  • In the keyboard settings - enable option Auto capital letters.
  • In ADB - run the command adb shell settings put secure auto_capitalization 1.
  • For system files - return the original version Generic.kl.
Are there applications that ignore keyboard settings?

Yes, some applications (for example Microsoft Word or Google Docs) have their own autocorrect mechanisms that may override Android settings. In this case, disable auto-edit directly in the application settings.
