I like to keep a backup of all my received/sendt texts and all info regarding my calls.
I do this by using SMS Backup + (
https://f-droid.org/repository/brows...oggles.smssync ), but I don’t use Google – I use FastMail.
At the time of this writing (2016-08-11) there is an issue with the package in F-droid, so you have to use an APK from another source.
So the following is needed to use SMS Backup + with FastMail.
First login to FastMail, go to Advanced Settings, and select Alternative Logins. (You need to NOT use an alternative login when viewing this.)
