Using the Barcode Scanner app is pretty straight-forward. Simply follow the steps below:

  2. Point the camera to the QR code on your screen. You may use the one above if you wish to do so. Make sure that the QR code fits in the viewfinder rectangle. The orientation does not matter. You will hear a beep when the scan is successful.
  3. You will then see the content of the QR code and some additional information. Specific buttons will show up at the bottom of the screen depending on the content. For example, if you scanned a QR code to download an app or game you will see an "open in browser" button.
