Every time that a new Samsung App update comes out (most recently Samsung Pay), it selects to allow app installs from "Unknown Sources" (and doesn't change it back after the updates are installed). With the latest Samsung Pay update, every time the "Accept new TOS" thing pops up, it enables again things to be installed from "Unknown Sources". 😠
Also, there is no way of turning off, disabling or uninstalling Samsung Pay. 😠 I haven't had time to read the new TOS, and there is no way to NOT accept it.
This is amazingly irritating, and seems like a huge security issue that Samsung Apps are just enabling this without your knowledge or consent. 😞
