I'm unable to add other languages to my on screen keyboard, the only languages available are English, Spanish, Korean and Portuguese and even upadting doesn't change anything.
Hey @grayfox1574! Samsung engineers are currently working on an update to include more languages for the keyboard. I would recommend setting up your updates on automatic, so that as soon as the update will be released, you will receive it. In the meantime, you can use a third party app for the languages that you are missing.
