Hello @Algimantas,
If you would like to use the look of Quick Settings from One UI 6 you can follow the steps below:
1. Expand the Quick Panel and press the “pencil” icon to edit the user interface. Here, you get a new menu to manage “Notification and quick settings view.”
2. Separate and Together are the two options available in the software. You need to toggle Together to bring the old-style unified Notification Panel and Quick Settings.
Have a good day!
Have a good day! ☀️
