Dark Modes & Themes
Finally, Samsung phones have enjoyed some sort of dark mode for a while now, but with the Galaxy Note 10 and Android 10 it's officially better, works across the entire interface and with most apps.
You can quickly turn on Dark Mode (Night Mode) and enjoy black software elements instead of white ones. This is easier on your eyes and helps with battery life.
Samsung's dark mode works throughout the entire software experience, not just certain apps or interface aspects, but everything is dark and/or black. It's a system-wide dark mode (night theme) that you'll absolutely love. It's something a few other phones have, and now all Galaxy owners can enjoy it.
Then, themes shouldn't be new to most Samsung users because they've had a "theme store" on the last several Galaxy phones that lets you change how your phone looks. If you've never tried the Galaxy Theme Store, go do it, we'll wait. I use dark mode and a night theme combined for my preferred results.
