I typed in "What is she" and got it wrong. Is there any reason that it should be "What's she" instead?
Edit: My previous comment was factually wrong; I misread your comment and tried to explain why the sentence is actually ungrammatical. It's correct, though (as you said), and here's an explanation:
Typed "what have she" and was counted wrong. No other choice, because mobile has a list of words for you to use already.
"What is she?" Was wrong... correct answer was "What's she?" Awkward...
