Change Keyboard Height auf Xiaomi
The stock keyboard on Xiaomi phones uses a fixed height by default, which does not fit every hand size or screen resolution. If keys feel too close together or the keyboard blocks too much of the app above it, the fix is a dedicated size setting inside the keyboard preferences, not a system-wide display setting.
Open Tap on Settings ➔ Tap on Additional settings ➔ Tap on Languages & input ➔ Tap on Manage keyboards ➔ Tap on Settings ➔ Tap on Preferences ➔ Tap on Keyboard height ➔ Choose an option. MIUI shows seven presets from extra short to extra tall, plus a slider on most versions for fine control between the fixed steps.
A taller keyboard gives larger key targets and fewer mistyped letters, but it hides more of the app content, which matters in chat apps or forms with several fields. A shorter keyboard keeps more content visible but shrinks the tap area for each key.
This setting only changes the height of the built-in keyboard. If you use a third-party keyboard app, look for a similar size option inside that app instead, since MIUI's setting will not apply there.
