Yes the camera backup functionality works, but it is only one way (phone to PC). I previously had it setup two way, so when pictures were removed from the directory on the PC, they were removed from the phone. When I use the built in Camera backup option, there is no option to share it as read/write. If I try to add the directory by creating a new backup share on the phone for a custom folder, I never get an option to share it as read/write. If I first create the folder on the computer and try to share it to the phone with a read/write QR code using the DCIM directory the phone gives me an error that the directory is already shared.
