Why does autocorrect change what I type into non-english words or nonsense? IE work into wirk, my into muy, a single word into another word filled by a blank and a letter or two. Some common words don't even show up as choices
Try going into the language and input settings and then select Samsung keyboard then about samsung keyboard and see if there is an update for it.
i'm not surprised that auto correct isn't working, translating from one language into another!!
