Lets say I make a call to Smith, after searching my contacts. I put "smi" in the search box. The next time I need to search contacts, the letters "smi" are still there, making it necessary for me to tap the rectangle to open up a search box, delete "smi", then search. Does anyone know if there is a way to make it so my last search is not kept on the box? ie clear the box after each search.
