So I have a samsung mesmerize, and a few days ago I accidently opened my camera on it and somehow manged to take a picture of a barcode on my water bottle. Well, when I tried it again it of course isn't working. I googled it and everything keeps telling me that you have to download the app. But I don't have that app downloaded, so do some phones come with a way you can do this without downloading it? And if so, how?
