Can't backup locally: gmail account is mandatory
My phone is NOT linked with a google account.
I have set "SMS Storage": to a local (writable) dir.
I click "BACKUP" button, and got:
"You need to connect your Gmail account first".
Is it really necessary to be connected to google account for local backups? Can I work around it, or suggest a fix?
