Have a GO620 and have upgraded from a Samsung S5 to a Oppo A91, running android9 (ColorOS v 6.1.2). When I try the Scan Code stage of connecting the phone, I get the message "An error occurred. Please try again later". Have rebooted GO620 and phone, uninstalled My drive and rebooted both. Obviously it has not tried or tried and failed to access the camera. Phone is perfect otherwise, is this an app problem or something to do with ColorOS?
