Earlier this month, Samsung announced the launch of the Galaxy Z Flip 4. The phone has a clamshell design that gives you a screen slightly larger than an average phone when you open it, and a compact 1.9-inch cover to see incoming calls or replying to texts when closed. The CoverScreen OS app gives this small screen much more functionality.

The app is free to download on the Google Play store, but some features have an additional cost. The Galaxy Z Flip 4 is priced at $999, placing it on the more expensive side of the smartphone market. This free app helps you maximize your investment by letting you listen to music and browse emails without even accessing the main screen.
