Can you check the incoming call directly in the second screen?
With second screen enabled you can accept or reject incoming calls even end calls that are
active. If using the Quick Cover case, incoming calls are displayed on the second screen
when case is closed.
How to enable
1. From the home screen, tap Apps ▶ Settings ▶ Networks tab (if applicable) ▶ Call ▶ Show
voice calls while in an app.
2. Select Second Screen.
※ NOTE : If second screen is not enabled or if you choose other option then incoming calls
will not display on the second screen.
