Changelog and security patch level
Samsung publishes the release notes for each update, including the security patch level, on its own site. They are listed per region – for example SM-M476B / INS release notes on doc.samsungmobile.com. Each region page here links to the notes for that code. We don't show the patch level ourselves because Samsung's update servers don't report it (why).
