With its version of Android Pie, Samsung flagship like the Galaxy S9 provide a much needed update to keep them competitive against rivals like Google Pixel 3 and OnePlus 6T. To distinguish it from other Android platforms, Samsung Experience has received a big face-lift called "One UI".
The update has not been officially launched yet, but a leaky beta building has enabled us to try some of Samsung's new features in Android 9.0.
One of the most obvious changes is an upgraded message panel on Galaxy's lock screen, which now has rounded corners to give it a slightly floating appearance. This reconstruction also matches the rounded corners found on the Galaxy S9, Note 9, and the upcoming Galaxy S1
The regular notification screen displayed when the phone is unlocked also received rounded corner processing while retaining the same basic layout available on Android 8 Oreo for acquaintance.
Android Oreo gave Galaxy owners the opportunity to set the transparency in notification backgrounds to make them easier to show, and this has transitioned to pie. However, access to this setting is slightly different, as the lock screen and security options have now been separated into their own sections.
As mentioned, to set your messages, select "Lock screen" on the main page of the App Settings, and then tap "Notifications" on the following page.
Inside "Messages", adjust the alarm screen's message panel by slide the "Transparency" field until you get the desired effect in the preview window. In addition, you can also press the switch in "Auto Reverse Text Color" to automatically change text from light to dark or vice versa, depending on transparency and backlight.
