I can't find any literature saying no, and I've tried maybe 5 of them. No functionality. Thanks!
The app simply called "barcode scanner" works fine on mine. Are you getting a specific error? Is Android Market just not letting you install them?
Yes they do. Most just don't work well. I use one called "ScanLife" available on the market for free and it works great.
I have the same problem. I can scan QR codes fine, but not barcodes. I found out that you have to have auto-focus on your camera, which Samsung Gravity's DO NOT! If anyone knows of a barcode scanner that works well for this phone without auto-focus,please let me know.
It doesn't help that the camera is only 3MP and a pretty low-quality one at that.
