Android MediaRecorder getMaxAmplitude always returns 0 on LG Optimus
<p>I am writing an app that basically just tests if we can get anything at all from the microphone.</p>

<p>It works perfectly on several android devices, but not on the LG Optimus. Everytime I call <code>MediaRecorder.getMaxAmplitude</code> on the LG it returns 0.</p>

<p>The device is successfully recording, because I can listen to the recordings.</p>
