The S-View Smartphone Flip-Cover Case with S Pen for Galaxy S21 Ultra 5G from Samsung changes the way you interact, utilizing an interactive transparent window and included S Pen stylus. Once inserted with the cover closed, your phone alters the display to accommodate the window. Through this window, the phone provides a specialized strip display with the time, date, battery status, and other notification icons. It can also display functions such as music playback and incoming calls. With the cover closed, you can tap the strip to manage playback, reject calls, or answer them.
