Android 2.3.7.r1 按menu键时会停止录像。改成录像时按menu键不做处理，可做如下修改：
在packages/apps/CameraOpen/src/com/mediatek/camera/VideoCamera.java
onKeyDown()方法中：
修改
代码如下：

case KeyEvent.KEYCODE_MENU:
if (mHeadUpDisplay != null && mGLRootView != null
&& !mAlertShowing && !mMediaRecorderRecording
&& mHeadUpDisplay.getWidth() != 0) {
mHeadUpDisplay.barsSwitch();
}
if (mMediaRecorderRecording) {
onStopVideoRecording(true);
return true;
} else if (event.isLongPress()) {
return true; // consume long press to prevent soft keyboard
}
break;
为：
case KeyEvent.KEYCODE_MENU:
if (mHeadUpDisplay != null && mGLRootView != null
&& !mAlertShowing && !mMediaRecorderRecording
&& mHeadUpDisplay.getWidth() != 0) {
mHeadUpDisplay.barsSwitch();
}
if (event.isLongPress()) {
return true; // consume long press to prevent soft keyboard
}
break;
