The Galaxy S20 has an ultrasonic fingerprint sensor that's embedded underneath the screen, and by default you can't see the sensor when the screen is off. Fortunately, you can change the option in the phone's settings and have the sensor always visible. Here's how to set it up.

Always On Display consumes a decent amount of battery, so make sure you monitor your Galaxy S20's battery usage to see just how much battery the feature is utilizing on a day-to-day basis.
The fingerprint sensor isn't quite as fast as older capacitive modules, but it does lead to a more seamless design at the back. And while it works with most screen protectors, you may run into issues with a few glass options.
