Here's how to wipe the cache for your Samsung keyboard app: go to Settings> Apps> enable "show system apps" from the 3-dot menu, and now find Keyboard app. Open the Keyboard app menu, go to Storage and use the 'clear cache' option. Confirm.

If the Keyboard still doesn't work after that, then you should clear the app data, too. Go to Storage like you did above and use the 'clear data' option. Confirm and then you're free to test the keyboard app once again.

Install all Keyboard app updates and Android firmware updates

Try to update the Samsung keyboard app to its latest version, and see if that fixes the problems. If the app is updated, then you should try and update the installed Android OS to its latest possible build.

  • press and hold Power button for the power options to load.
  • now tap and hold the "power off" icon - it will turn into "safe mode".
  • tap once Safe Mode and confirm the boot.
  • when the Safe Mode boot is done you need to check for bad apps.

Make sure that after you remove one app you boot the phone in normal mode each time.

  • release the buttons when the Android logo appears over a blue background.
  • wait 30 seconds more for the Recovery Mode menu to load.
  • select 'wipe cache partition' option.
  • confirm and reboot the phone after that to verify if the Keyboard app is working.
