📱 Android: App goes to background after answering call, CallKeep screen remains on top

When answering an incoming call using React Native CallKeep on Android, the app automatically moves to the background, while the CallKeep UI (system call screen) remains visible in the foreground.
Expected behavior is that the app should come to the foreground (or at least be accessible immediately) once the call is answered.

Steps to Reproduce

Use displayIncomingCall to show an incoming call.

Answer the call from the CallKeep screen.

Observe that:

The call connects.

The React Native app goes to background.

The CallKeep screen remains visible or locks focus.

Expected Behavior

After answering the call, the app should either:

Automatically return to foreground, or

The CallKeep UI should dismiss, allowing the user to interact with the app directly.

React Native version ,0.79.3
React Native CallKeep version 4.3.16
Android Version Android 13

Start by tracing the Android handling of displayIncomingCall through the answer flow and CallKeep UI behavior on Android 13. Reproduce with React Native 0.79.3 and CallKeep 4.3.16, then verify that answering either restores the app or dismisses the CallKeep screen so the app is immediately accessible.
