Android camera fails to read QR Code


Recommended Posts

At first, my S4 read the QR code fine, but now it won't. The camera keeps re-focusing and never captures the thing. Perhaps the problem only began when the app was updated. Manual entry is a real pain. I've seen this problem referred to in scattered places, so maybe it's worth devoting one thread to tracking it.

My Note 2 read the QR code, no problem.

EDIT: It started working. First on a different monitor, and then on my MacBook Retina where it had been failing. I suspect some Android permissions might have been involved, although I did do a reboot after enabling the BTSync app to have more permissions.
