I have tried signing out of the Samsung account and every time I scan the QR code to link my Note 20 to the S7+ it opens Samsung Notes with the script below
I can the scan QR codes. I cant get my note 20 ultra to link with my s7+ for text and phone calls. My note 20 is locked to Verizon so that may have something to do with it.
Actually I think it may have something to do with samsung qr code scanner. I think it is not working right as I have seen some people complain about it opening up notes instead. I know it opens up notes for me as well after giving an error stating something like it couldn't find an app to open the link. Not sure of a good third party app but there are many of them.
