Screens shots that purportedly show the new Android homepage, possibly called Facebook Home, show buttons along the top for common Facebook actions, such as updating a status, posting a photo or checking into a location, and icons for the major Facebook apps including Instagram and Messenger in the center of the screen.
My suggestion was that they should have built a text search box on a new version of their homepage, while directing just 1% of their home page visits to that dummy text box for a period of a week or so.
