QR codes simply DO NOT WORK on or from my Communicator
I have tried pointing the camera at them, pressing the button ... & I get a nice picture of the QR code ... that's it.
That's.... fully expected? Personally, I would like to beable to take a picture containing any barcode, unless I chosoe otherwise.
Anyway, you need a separate application, since Cosmo seems to use unadultered camera appliation - I am using Opera and its built in 2D code scanning ability (since I am using Opera anyway)
