If you want your home page to load each time you start the browser, you will have to make sure all tabs are closed when exiting. I don't see anything in the settings that will allow you to set "close all tabs on exit" (like other browsers have). You can just press the "home" icon on the tool bar (either the top or the bottom, depending on where you set it to be placed)
There's a reason a lot of people don't like Samsung Internet.
