New Samsung "ClockFace" app adds 30 clock styles for the Always-On Display
The ClockFace app gives you options for the AOD on newer Samsung phones
ClockFace offers you the option of choosing different clock styles not only for the AOD display, but also for the lock screen. You can change the color of the clockface you select, or have the color change based on the lock screen wallpaper you have up. The clock styles available include both analog and digital options, and some show the day and date. You can view a few of the available choices by checking out the screenshot of the app that accompanies this article. All 30 options can be seen by clicking on the slideshow below.
While the app is from Samsung, the company has not yet added it to the Galaxy Apps Store. That means that you will have to sideload it from APK Mirror. All you need to do is click on this link and follow the directions. Once the app is installed, go to Settings > Lock Screen And Security > Clock And FaceWidgets > Clock Style.
