I’m about to switch my outdated Samsung tablet and smartphones to LineageOS. But I want to make a backup of my device, including the OS and everything, in case something goes wrong and I need to flash the original OS back into the device.
How do I proceed? I think I need to do a Nandroid backup or something? Is that correct?

Or root it and use your tool of choice. Nandroid backups haven’t worked for years.
