As Samsung's very own version of Android 9.0 Pie, the newly named One UI (formerly Samsung Experience and previously TouchWiz) features a slew of new features and redesigned Galaxy interface elements. Many of the changes, such as The revised native app icons are obvious, but other features have been subtly improved, which greatly improves usability.
The Edge-Lighting effects of the Galaxy are such a feature that has undergone no major transformation on Android cake. Instead, Samsung improved the system by essentially streamlining the settings and adding more options, resulting in better accessibility overall.
Prior to the One interface, Edge Lighting was pretty limited in terms of accessing notifications. While you can set up to quickly answer calls and messages with the phone's heart rate sensor, you have not been able to do much else but interact with the Edge Lighting notifications on your screen. With Android Pie, you can now respond to Edge Lighting alerts with a series of gestures.
There is now an option to enable the "Edge Lighting Interaction" feature that allows you to access alerts such as text messages, phone calls, and information displayed more directly from the feature. It's also worth noting that Fast Reply has been moved from Oreo's three-item menu page to the feature's main settings page to significantly reduce confusion.
As you can see from the screenshots below, interacting with Edge Lighting alerts consists of a series of gestures. These gestures include tapping the notification to go directly to the app, do a sideways swipe on the alert to discard it quickly, and swipe down from the notification to use the app as a pop-up window for multitasking to open.
The most annoying aspect of Edge Lighting was how brief the warning was, which made it very easy to overlook them. Fortunately, Samsung has resolved this with One UI. In addition to the well-known options for lighting effects, colors, transparency, and width, you can now adjust the duration of the feature to make sure you never miss an edge lighting warning again.  Overall, the use of the updated Edge Lighting feature is becoming much more attractive, especially due to the above-mentioned practical improvements. Since One UI is officially in the wild, we'll be looking for more Android Pie features that will be displayed on Galaxy devices. So check for updates regularly.
