One of the V20’s defining features is the second screen above the main one. This small ticker can show app shortcuts, notifications, and more. You should probably make some tweaks, though. By default, it shows a “signature” most of the time. If you need help remembering your name, maybe that’s good enough for you. For everyone else, head into the Display settings and tap Second Screen.
You can change the settings for what is displayed when the main display is on and off. Date and time is handy when the screen is off, and the quick tools are always just a swipe away. When the display is on, you can have multiple toolbars accessible like custom app shortcuts, recent apps, music controls, and contacts. Take a few minutes to try them various options out.
