Every possible vibration button is turned off, vibration intensity is set at zero, and there is only a vibration ON function ("also vibrate for calls") - there is no vibration off button under sounds. When I tap the microphone in a Google search, it vibrates. When the search generates a response, it vibrates again. When I turn the volume on the ringer all the way down, and the phone rings, it vibrates. The only way to stop vibration that I have found is to put the phone on completely silent. But that's not very functional when you need to hear your phone ring. Please help! Thanks
