If you periodically got a white screen instead your view of camera - use:

private void releaseCameraAndPreview() {
        if (mCamera != null) {
            mCamera.setPreviewCallback(null);
            mCameraView.getHolder().removeCallback(mCameraView);
            mCamera.release();
            mCamera = null;
        }
    }

and put it here

try {
            releaseCameraAndPreview();
            mCamera = getCameraInstance();
        }...

and here

@Override
    protected void onPause() {
        super.onPause();
        releaseCameraAndPreview();
    }
