Does anyone else here have problems getting the camera of a Samsung Galaxy tab2 7.0 to recognize QR codes? It's always too fuzzy or far away for Barcode Scanner or Google Goggles to recognize anything. I thought I could remedy this with a magnetic stick-on lens (

So, I'm asking you users of the Galaxy tab2 7.0, is there some other stick-on lens that I can use to get acceptable focus on a QR code?
