Not sure what you mean? I don't have any man's head on the top left hand side. I do have an issue with a disappearing keyboard after typing one letter in the search box, is that one of the abnormal things Google is doing on your iPad Air? I have never had the head in the top left side.
Could you be more specific about what else is not normal? What else is or isn't it doing?
I tried Google Chrome and it didn't have the issue I have but I did not like the Chrome and went back to the disappearing keyboard. If that is one of your issues, you can give that a shot. Maybe you will like it.
Please get back with more specifics of what the issues are. Maybe someone else can be of more help than I was able to be. It might be a Google issue and someone here would probably know.
