As from today I suddenly got a Google search bar with the microphone for voice search on the end, all across the top. I followed an on-line guide telling me how to disable it, which I did in the apps (under the app Google Search). Now I still have the bar across the top but it doesn't do anything, no search, no microphone showing, nothing. So I thought I'd go back into settings to enable it again - but it's not there anymore to alter. Google Search, plus Voice Search have disappeared from my Apps altogether. I went to the App Store to get them again but it says "Already Installed". What on earth do I do now? I'm really worried!!!
