Android typing issue

Hello Everyone,

For some reason whenever I type anything (email, text, this post) with my Samsung Note 5 the first sentence starts off with a space, meaning the first word is not capitalized. It’s almost like it is automatically indenting for a paragraph. So when I type I always forget and end up having to go back and delete the first letter and space to capitalize the first letter of the first st word. How do i change this so the first letter is not indented and is capitalized?
