I'm using the barcode-reader project in two Samsung devices (SM-N9005 or SM-G920F) and they are not capable of recognize any barcode. There are no problems in others like One plus one, or others Samsung devices like S3 or S4.
There is not a problem of the autofocus, because it is working fine, the barcode is focus properly.
With this devices, the camera opens but nothing happens.
HELP please.
