I have just changed my 18 month old HTC Wildfire to an HTC Desire C however, I don't seem to be able to scan bar codes successfully with my new phone. The Amazon App, and various Bar Code scanning apps just don't seem to work. Most of the apps tried seem to have little green balls running and flickering along the red line which I assume you have to hold over the bar code but nothing happens. However, if I scan a QR code that works fine??? Am getting very frustrated as my old phone didn't seem to have any problems in doing this. Is it user error or have I just made a bad choice in my phone selection?
