It used to work fine  but now every time I scan a QR code it will display the link of the page the QR code points to and after I either go to the page and then come back to the app  or just close the link and return to the app I get a message that the camera has failed and that I may have to perform a system reboot to re-enable it. This not only prevents me from using this app again  but it also disables my phone's camera! I have to reboot my phone to get the camera to work again. FAIL! This never happened in the past. I don't recall the last time I used it  so I don't know how many updates have been published since that time to narrow where the issue first came up. Too bad... I liked this WHEN it worked. Will have to check out the competition's offerings.
