⏮️ This emoji is in the shape of double left - pointing arrows. It is usually used to indicate going back to the beginning, moving backward or reviewing previous content. For example, when playing multimedia files such as videos and audios, it may mean going back to the very beginning position, or when browsing a series of items, it means going back to the first item.
We can click ⏮️ to review the previous video.
In the music list, ⏮️ can enable you to return to the beginning of the song.
