FaceWidgets are useful information that are displayed on the lock screen, and if supported, on the Always on Display, of the Samsung device. This includes, for example, a music player to pause the music or skip the song, but it can also display today's dates, the next alarm (also stopwatch/timer) or the weather. By default, only the music is activated.

If desired, the order of the FaceWidgets can be rearranged.
