App Logout / Termination Behavior When Changing Bluetooth Settings With and Without Multitasking

I would like to share an issue observed during app development.

When changing Bluetooth settings from the system Settings app without using multitasking, the app does not terminate but instead logs the user out.

However, when changing Bluetooth settings while using multitasking, the app terminates completely.

In this context, I would like to understand:

Whether there is any system behavior that causes the app to refresh or restart when Bluetooth settings are changed

And why the app behavior differs in a multitasking environment, particularly in terms of app lifecycle handling

Any insights into these behaviors would be greatly appreciated.

“while using multitasking” means reducing the app’s size and displaying it side by side with the Settings screen at the same time. For better understanding, I will attach an image.

Additionally, I found that YouTube also terminates when the “Allow Tracking” permission is changed in Settings while using the multitasking interface.
