To everyone who has problems with automatic backup on Android 7.0 Nougat: 1) go to Settings > Apps > SMS backup > Data usage and switch unrestricted data usage ON... 2) then go to Settings > Battery > three dot menu (up right corner) > Battery optimization > drop down menu """"""""All apps"""""""" > SMS backup > Don't optimize > DONE. Now auto backup is working again. You're welcome. PS: it is tested only on my Nexus 5X. If you have a different model and/or altered OS  then write the review here to let everyone know was it successful or not.""
