I’ve been looking around to find a good, privacy respecting way to sync my messages between phones. I decided I’m going to use SyncThing so I don’t have to mess around with a server. The only problem with this is that I haven’t been able to find any apps that work on modern Android that routinely backup and import messages from a file/folder into the messages database. Does anyone know any app that might do this?
That looks promising, much appreciated. I should also mention I also mean to back up MMS along with SMS.
Then I’m glad to be of at least partial assistance with your search. Ah, I’m not entirely sure if it does, and I can’t presume so due to it including the entirety of the messages, and I unfortunately can’t check, as I don’t have any MMS to save.
I do however hope it does, but if not, I wish you the best of luck with your search, and that others will chime in with more effective solutions.
This can be done no matter what SMS/MMS app you use, but it is slow.
