I was reading an article online about how to use the default search button (looks like magnifying glass) to use voice activation to send text message, email, so on. it requires you to long press the search button. well, my search button is missing. I have the google search, but not the default with the magnifying glass. if I hit Options I see the search button there, but dont see a way to add it to the desktop. how can I get this back on my desktop?
