When I do scan upc the iPhone camera light automatically turns on but it causes a big glare (sometimes covering the whole upc) and takes a while to move it around and get it to focus. Once in a blue moon the light won't come on and I can focus and scan significantly faster. Is there anyway to turn off the camera light to not have it pop on automatically? I'm scanning in a new library of several hundred DVDs and this feature is actually slowing down an already lengthy process.
