First I want to say this is a amazing project, especially when I dig into the code.
Then i have a failure case that it can not read the qr code.
I made my own qr code reader with the latest core.jar.
Everything worked fine until I tried to read a qr code which has a very simple data like a string "abc".
The decoder could not get the result.
This situation only happened when I tried to read the code at a relatively close distance(around 4-5 inches) between the camera and the qr code. But it was not that close, the camera can focus perfectly.
But if I moved the device far enough from qr code. it started to work. Also if I tried to read a qr code which has more complex data, it worked perfectly.
Same failure happened on the Barcode Scanner(zxing app). I tried to read a very simple qr code with the app. put the device close enough but the qr code was still in that rectangle. it can NOT get the result.
Is this a known issue?
