Most of the time it is right, for instance if I say "I bought two sticks of gum too." It's gets that right. But sometimes especially longer sentences it types what I say correctly, but sometimes goes back and thinks it's correcting itself and it's wrong again. Is it sort of proofreading what I'm saying and thinking it's making it grammatically correct for me? It's annoying especially when I'm texting or posting, and I look at what was sent, and it changed it before I had a chance to re-correct it.
