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.
This can be done no matter what SMS/MMS app you use, but it is slow.
