I can understand your thinking. Samsung has introduced security mechanisms with its firmware updates since 2018, especially since Oreo 8.0.0, to make it more difficult to change the operating system. Although there are solutions to install another operating system anyway, e.g. Android 7.0 or /e/OS, the intervention in the Oreo 8.0.0 system has its risks. “It’s Lombard Street to a China orange.” (There’s no changing that).
In a few months the installation of /e/ OS should become much easier with … An /E/asy Installer!
