   Auto blurs
   Auto focus is now auto blur. I thought it was my camera or some gunk on my lens, but     no, quick clean and test with regular camera app confirms that it's the app that's broken.

   Does not recognise a lot of barcodes...
   The app does not recognize a lot of barcodes that it should since they belong to      books..hope they fix this...

   Never works on Galaxy Q
   I don't know if it's because of the phone or what but this app has never worked on any bar code I've tried. Won't focus on it at all.

   Does not do all
   This is a good app but it does not scan normal barcodes only the ones that are     desinged for smart phones but would be 5starts if they fig this
