Why does samsung tablet s2 capitalize word immediately before exclamation point?

[AC Question]

When I type a word followed by exclamation point, the word is changed to start with a capital letter. If I click the word, I'm given the option to change it to lower case or delete the word. Very annoying.

I wish I New! I don't even get an option to switch to lower case.
