I switch from Google Android to LineageOS and prepare all my data to be ready for the switch. Everything is on Nextcloud so, Contact, Photos, etc are already out of my device. I want to backup SMS/MMS messages and Call log. I can backup them with Samsung Switch, but is there a way to import them in LineageOS after?

Update 1

I'll not install LineageOS with Google Apps support, so any apps from Google Play will not be able to run after the LineageOS install. I can install app from F-Droid or run command line in Linux shell if needed.

Thank you!

  • I found "SMS Backup+" on F-Droid. I know Google introduce sensitivity scopes, and as a result some API don't work anymore like MMS backup. I'll give it a try...

    See the app description, it can backup to cloud (few types of cloud) or to xml format

    Optionally is a funny wording. android apps rely on google APIs, you need at least a replacement for GmsCore (like microG, Open GApps or MindTheGapps). btw you can download apps from Uptodown, APK Pure, APKMirror or similar without using google play store

Thanks to @beeshyams for his comment.

TL;DR

Just install SMS Backup & Restore or download it from apkmirror. Copy apk to SD card. Do a backup of SMS/MMS messages (don't forget to enable MMS images/file/etc in advanced settings) and Call log to SD card. After the switch to LineageOS, install APK from SD card and import SMS/MMS messages and Call log. Done.

Story (and issues)

I finally switch from Android 5 on my Samsung Galaxy Note 3 (don't laugh, it still rocks!) to LineageOS 16.0 following Install LineageOS on hlte.

After a backup of my data (see TL;DR), I boot in recovery mode and at the Installing a custom recovery using heimdall step, the command

heimdall flash --RECOVERY <recovery_filename>.img --no-reboot

did not work properly.

My shell fail with :

ERROR: Failed to confirm end of file transfer sequence!
ERROR: RECOVERY upload failed!

and my device show a "SECURE CHECK FAIL : recovery".

From this post,

"it was the Samsung Reactivation Lock that was blocking me. Upon booting the phone, going into Apps > Setttings > Security and then typing in my samsung account password I was able to disable the lock [...]"

And recovery file upload success!

After the LineageOS install, I use SMS Backup & Restore again to import data.
