Why is it that when I write on Googles keyboard on my phone and misspell something it has no idea what I am trying to write but if I Google the same word it knows instantly what the word is?

Autocorrect has gotten worse and worse. I can transpose two letters and it won't suggest the right word, but it'll suggest the right word with an apostrophe and an S that makes no sense. It's not wonder so many people think plurals need apos'trophe's.
