Install for UI Improvements
If you like customizing the look of your Galaxy A, you should think about installing Android 8.0 Oreo in the near future.
Samsung's Experience 9.0 UI delivers some new customization options including some new styles for the Galaxy A series' Always On Display.
Once you get Android Oreo on board, you'll notice new clock styles for your Always On Display. You'll find them in the Clock Styles hub.
If you're running Android Oreo your lock screen clock should also change color to match the wallpaper you’re using on your device.
On Android Oreo you'll also now be able to touch and hold an app to display common or recommended shortcuts to tasks within the application.
For example the YouTube app's shortcuts allow you to quickly view Trending Videos, manage your subscriptions, or Search for new videos.
A lot of apps don't support this feature yet, but we expect a steady stream of support updates throughout the year.
