1. Enlarge the keyboard through MIUI settings

The easiest way is to take advantage of the built-in MIUI options.This method works on all firmware versions (including MIUI 14 for the Poco X3 Pro), but the path to the menu may vary slightly.

2. Hidden settings in the "Laboratory" MIUI»

💡

If the keyboard starts to crop around the edges after resizing, reboot the phone, which will reset the interface cache and apply the settings correctly.

3. setting up third-party keyboards (Gboard, SwiftKey)

If you use Gboard (from Google) or SwiftKey (from Microsoft), the sizing algorithm will be different.These keyboards offer more customization options, including one-handed mode and smooth zooming.

For Gboard:

4.Using gestures for quick scaling

MIUI 13/14 has a keyboard gesture feature that allows you to temporarily increase its size with a pinch movement (as with zoom photos), which is convenient if you need to quickly type long text, but constantly large size interferes.

To activate the gestures:

1. Open Settings → Additional settings → Language and input → Current keyboard.
2. Choose Gestures (or Gesture Management).

• 🔄 Return the standard size with a double tap.
• 📱 Move the keyboard across the screen (useful for one-handed input).

⚠️ Note: Gestures do not work in all apps, for example, in WhatsApp or Telegram, zooming may be blocked due to conflict with the internal settings of messengers.

5. Problem Solving: Keyboard resets or doesn't change size

Sometimes, when you resize your keyboard, you reset or you don't apply the settings, because of MIUI and cache conflicts, and here's how to fix common errors:

Problem 1: The size is reset after rebooting.

⚠️ Note: This is due to the Adaptive Optimization function in MIUI. Turn it off: Go to Settings → Annexes → Application management. Find your keyboard (like the keyboard). MIUI Select Battery Limitations or Gboard. → No restrictions. Turn off Adaptive Optimization in the app menu.

Problem 2: The size slider is locked.

• 🔓 Check if the Child Mode or Parental Controls are enabled.
• 🔄 Update the keyboard via Google Play (for the first time) Gboard/SwiftKey).
• 📱 Remove System Keyboard Updates in Settings → Annexes → keyboard MIUI → Remove updates.

Problem 3: The keyboard is cut off on the sides.

This is because the DPI screen is not corrected.

1. Install the Display Info app from Google Play and check the current DPI.
2. If the value is greater than 400, lower it using ADB: adb shell wm density 380
3. Reboot the phone.

💡

If the keyboard “slides” sideways after changing the size, reset the display settings in Settings → Screen → Screen resolution → Reset.

6.Alternative methods: ADB and third-party utilities

If standard methods don't work, you can use advanced settings through ADB or specialized applications, which require caution but give you maximum control.

Method 1: ADB-team

Connect Poco X3 to your PC and do:

1. Activate USB Debugging in Settings → About Phone → MIUI (7 taps) → For Developers.
2. In the command line, type: adb shell settings put secure keyboard_height 150 (where 150 — percentage).
3. Reset the device.

Method 2: Keyboard Size Changer

The utility from Google Play allows you to resize any keyboard, including the system keyboard.

⚠️ Warning: Some antiviruses (e.g. Avast) block Keyboard Size Changer as a “potentially dangerous” application. This is a false positive – add a utility to exceptions.

7. Optimal settings for games and messengers

For comfortable chat in games (for example, in Free Fire or Call of Duty Mobile) or quick dial in messengers (Viber, Discord), the following settings are recommended:

For games:

• 🎮 Keyboard size: 120% (to keep the game interface open).
• 🔄 Transparency: 70% (in the laboratory) MIUI).
• ⚡ Quick Access: Enable Floating Keyboard in Gboard Settings.

For messengers:

• 💬 Size: 130-140% (optimally for thumbs).
• 🔍 Auto Replacement: Disable in Keyboard Settings → Text input.
• 📱 Vibration when pressed: turn on for tactile feedback.

For the Poco X3 NFC (contactless payment model), it is also useful to enable Quick Answers in the keyboard settings, which will allow you to send template messages (for example, “Can’t talk right now”) directly from the lock screen.

💡

In chat games (like Roblox or Minecraft), use a separate keyboard in Gboard, which divides the keys into two parts, which is convenient for holding the phone with both hands.
