I am an app developer.
For OneUI, the initial view of notifications is only in collapsed view since Android 12.
The expanded view is only shown by pressing the down arrow button to the right of the notification.
I have tried to see if it is possible to set the initial view of notifications to expanded view on the app side, but it is not possible.
I also tried various settings for notifications from the Settings app on the device, but it was impossible.
On the Pixel devices, the most recent notification is shown in expanded view.
This is automatically controlled by the Pixel OS.
In the case of OneUI, it seems that the initial view of all notifications is controlled to be displayed in collapsed view.
Is it possible to make OneUI also display the notification in the expanded view?
