Good to know
- The recording uses dark mode, so the Settings screens in these screenshots are dark; the steps are the same in light mode.
- The font list here offers Default, SamsungOne, Gothic Bold and Roboto, plus Download fonts for more choices.
- Changing the font style does not change the font size; the size slider on the same screen stays where it was.
