In the Messages app, Samsung has added a new Recycle Bin where deleted messages stay for up to thirty days. The phone app has a new option to help you quickly delete duplicate contacts in the One UI 3.0 update. The background can be set to a still image or a video. Starting with the Phone app, you can now customize the call screen by changing the background and/or the layout. While there are slight tweaks in several stock Samsung apps, the Phone and Messages app changes are worth mentioning. You can now apply GIFs and still images as AOD wallpapers. Samsung also tweaked the Always-On Display (AOD) a little in the One UI 3.0.
Apart from that, the Dynamic Lock screen now has more wallpaper categories to choose from, such as Plants, Cats, Special, etc. Here you can add widgets for Digital Wellbeing, Weather, Bixby routines, etc. Big changes include the added functionality of widgets, i.e., you can see the widgets right on the lock screen by tapping on the clock.
