mr_P hey man, it does... After you have installed the application, you have to go into settings (in shazam) and turn of audio alerts, you'll see it'll work.
From FCC test report: “The only difference between RM-335 and RM-333 is that RM-335 has had all WCDMA and WLAN components removed“ and ”The test results of QURRM-333 are re-used for certification of the QURRM-335“.
