Microphone in use by another application

Android users may get the error message that their microphone is in use by another application. This is often caused by Google Now. Google Now optionally offers the possibility to always listen to the user voice. This way the microphone is constantly in use.

Here's how to deactivate it:

  1. Open the Google app
  2. In the top left corner of the page, touch the menu icon > Settings > Voice > “Ok Google” detection.
  3. Check the box next to From Google app
  4. For certain devices, you can also change some settings to turn off “Ok Google” detection outside the Google app:
    • Uncheck the box next to From any screen or Always on
