Samsung Keyboard is the latest proprietary Samsung app to be published on the Play Store, so you can grab the latest updates without waiting for an update to the operating system itself. The app seems to have been put up on the Play Store late last month; for now, it’s only supported on the Galaxy S8 and S8+, but support for more devices will no doubt be added in the future.
If you own a Galaxy S8 or S8+, you should see an update for Samsung Keyboard available on Google Play. The update doesn’t have anything other than bug fixes or improvements, but future updates should have more to offer.
