Android phone not displaying incoming calls

Pop-up display calls refer to a feature in some Android phones that allows incoming calls to be displayed as a pop-up window on top of the screen, instead of just a full-screen call interface. This feature provides more flexibility and allows the user to use their phone while they are on a call.
To enable pop-up display calls, you need to go to your phone’s settings, find the “Calls” or “Phone” section, and check for notifications>incoming calls> then look for the option to enable pop-up display for incoming calls. The exact location of this option may vary depending on your phone’s make and model.
Once the pop-up display feature is enabled, incoming calls will appear as a floating window on top of the screen, which can be moved, resized, or dismissed as needed. This allows you to take calls without interrupting your current activity on the phone.
