Open any text field |

Press the settings icon (⚙️)|

Check for the item "Size of the keyboard"-->

2. Screen size change (universal method)

If Gboard doesn't have the option to resize, the other way is to zoom in on the entire interface, and that will indirectly affect the keyboard, and it works even on older versions of MIUI.

Go to Settings → Screen → Text size and display. Here you will find two key parameters:

• 📱 Text size – increases the font, but not the scale of the buttons.
• 🔍 Screen size – changes the size of all elements, including the keyboard.

Select Screen Size and move the slider one or two divisions to the right. On Redmi 9A, the optimal value is "Large" or "Very Large", but not the maximum, otherwise the interface elements will be cropped. After applying the changes, reboot the phone, this will help avoid glitches with the display.

⚠️ Attention: This method affects the entire interface, not just the keyboard. Some applications (such as games) may not display correctly. If artifacts appear after the zoom change, return the settings to the factory settings.

3. Alternative keyboards with adjustable size

If standard methods don't work, try third-party keyboards with flexible size settings. The best options for Redmi 9A are:

🔹 How to install:

1. Download the keyboard from Google Play.
2. Go to Settings → System → Language and input → Current keyboard.
3. Activate the new keyboard and set it by default.

💡 Tip: Before installing, check reviews - some keyboards may conflict with MIUI. For example, SwiftKey sometimes resets settings after a system update.

💡

If the alternative keyboard doesn't show up after you install it, restart the phone, and it will reset the system cache and make changes.

If the keyboard gets glitchy, reset the developer's settings to factory settings (Settings). → Additionally. → For developers → Reset).
