This is NOT a duplicate of Why I can't scan the WhatsApp QR? or Can't scan QR code for WhatsApp web due to camera inverted or tilted on Galaxy Y Duos.
- I'm using CyanogenMod 11 (snapshot M12) on HTC One X
- I have the latest WhatsApp 2.12.250
I'm trying to scan the WhatsApp web QR code on my computer. On my Android Whatsapp, I'm able to get to the point where the scanner is active, and the green scan bar goes up and down, but it never manages to capture the QR code on my computer screen.
I tried to scan the same code using the ZXing Barcode Scanner, and it only works when I turn on "Use auto focus", "No continuous focus", "No exposure".
The camera lense on my HTC One X is slightly scratched up, and the camera pictures has long been foggy. I suspect that the combination of my crappy camera and the computer LCD screen is preventing me from scanning the QR code.
So, since I can't change the camera setting in the Whatsapp QR scanner, is there any tip on how I can maximize the scannability of this web QR code?
