The Galaxy S8 and Galaxy S8+ get Samsung's new One UI which means they get Night Mode. Night Mode is perhaps our favorite change in the new user interface and it's a great reason to try out the Android Pie beta.
If you're unfamiliar, Night Mode makes the Galaxy S8's screen a little easier on the eyes, particularly at night. It can also help you conserve battery life.
When Night Mode is active on your device you'll also notice changes across the user interface. Most of Samsung's stock applications are compatible.
You can manually turn Night Mode on whenever you want to use it or you can also schedule when you want your Galaxy S8 to turn Night Mode on.
There's also a way to set it so the device automatically turns Night Mode on when you're in the dark.
