2. Click Remove (if the button is inactive, first turn off the keyboard in Settings → System → Language and Enter).
3. Install Gboard again from Google Play.

For the Mi Keyboard, reinstallation is not possible – it is a system application, in which case only a complete reset of the phone (see the next section) or a switch to a third-party keyboard (for example, SwiftKey or Fleksy) will help.

Reinstalling the keyboard is the most radical method, but it is guaranteed to solve problems with the T9 if they are caused by damage to the application’s system files.
