Hi Bilgerat, under Samsung keyboard settings, scroll down to, Select third party apps to use. In there is a toggle for Grammarly. Turn to on...You could alternatively use SwiftKey as its already preloaded. Hope this helps.
I tried Grammarly which was introduced after a recent update and it seemed.to send my Samsung Keyboard haywire so I reset it and toggled off Grammarly.
@BilgeRat: Please head to Settings > General Management > Samsung Keyboard Settings > Auto Spell Check > Toggle on the relevant language e.g. English (UK). This feature will underline misspelled words in red, and suggest corrections.
