Android 9 Pie vs Android 8.0 Oreo Walkthrough: What’s New

Smarter Notifications, Quick Reply

Another big change to the pulldown bar overall is regarding notifications. You'll notice a lot of small changes when you pull down the bar and check incoming messages and such. Both on the lock screen, or in general, all notifications have rounded edges. On Android 8.0 it was squared off. 

However, the notifications are getting an improvement, yet again, on top of Oreo. They're smarter, more powerful, bundled together, and the "reply" feature inside the notification bar is better than ever. 

Now, with Android 9 you can see images, stickers, and media in the notification bar before you open a message. We get big helpful previews. The in-line reply is smarter and easier to use, too. These are subtle yet welcomed changes. 

The idea here is improved visibility and usability of notifications, and the entire notification and quick-settings menu on Android.
