Through the Hivoox marketplace, many users rely on Grandstream devices for daily operations, so restoring proper functionality is essential for smooth professional communication.
Why the Call Screen May Disappear

The system may minimize the call screen while keeping the call active in the background.

How to Restore the Call Screen (3 Reliable Methods)
Method 1: Use the Home or Back Button
Press the Home button or Back button on the device.
This brings you back to the main home screen.
From there, the active call notification should allow you to reopen the call screen instantly.
When to use this method:
If you think you accidentally navigated away from the call.
Method 2: Access the Call Status from the Dropdown Menu
Swipe down from the top of the screen to open the Android dropdown menu.
Look for the notification labeled “Call Status”.
Tap it to immediately return to the call control interface.
This is the most direct method because the device always keeps call status visible in the notification panel.

Go to the phone’s main menu.
Open the Phone or Dialer application.
On the right side of the screen, select the active line associated with the ongoing call.
