Language & Input on a Realme phone controls which keyboard languages are installed, which layout is active while typing, and how you switch between them. It is separate from the system language shown in menus and apps. You can keep the interface in one language while typing in several others, which matters for anyone who writes in more than one script or dialect on a daily basis.
What Language & Input Controls
The built-in keyboard (usually Realme's own or Gboard, depending on region) treats each language as a separate installable layout. Every layout comes with its own autocorrect dictionary, word suggestions, and key arrangement. A German layout, for example, uses QWERTZ, while a French layout uses AZERTY. Adding a language does not change your phone's display language; it only adds a typing option.
Adding a New Keyboard Language
New layouts are downloaded as small language packs. Some packs include predictive text and glide-typing data, so they can take a moment to install over Wi-Fi. Once added, a layout stays available until you remove it, even after software updates, though occasionally an update resets the active keyboard app and you need to re-enable a language pack manually.
Switching Between Layouts While Typing
With two or more languages installed, a small globe or language icon appears on the keyboard itself. Tapping it cycles through your active layouts without leaving the app you're typing in. Some keyboards also support space-bar swipe gestures for the same purpose. If you type in one language far more often, setting it as the default layout keeps autocorrect accurate and avoids frustrating misspellings in the wrong dictionary.
Managing Third-Party Keyboards
If you install a third-party keyboard app, language management moves into that app's own settings rather than the system Language & Input menu. Each keyboard app maintains its own list of downloaded languages, so switching keyboard apps means reinstalling the languages you need inside the new app.
When to Remove or Reorder Languages
Unused layouts still take up storage and clutter the language-switch menu. Removing languages you no longer type in speeds up switching and reduces the chance of autocorrect picking the wrong dictionary. Reordering the language list puts your most-used layouts first, which is useful if you regularly type in three or more languages and want fewer taps to reach the right one.
A common source of confusion is expecting the system display language to change after adding a keyboard language. The two settings are independent: changing what you see in menus requires a separate step in the general system language settings, not the keyboard language list.
