The camera must be released to avoid issues with other android implementations, check the last implementation:

```
public void onPause() {
		super.onPause();
		mBeyondarCameraView.releaseCamera();
		mBeyondarGLSurface.onPause();
		BeyondarSensorManager.pause(mSensorManager);
		if (mWorld != null) {
			mWorld.onPause();
		}
	}
```
