Single Cycle, Cycle, Arrow, Clockwise
This is a "repeat cycle" button. The symbol is usually depicted as two clockwise curved arrows, and a circle is marked on the curved line. The Arabic numeral "1" is also depicted on the circle. The "repeat loop" symbol is often used for multiple repetitions. When we are crazy about a song or a series of mv, we often use it, so that we can listen or watch it repeatedly. Therefore, the emoji can not only be used to refer specifically to the media player, or to represent the single cycle, but also to do something repeatedly, or to express the meaning of stubbornness and inflexibility.
The icons of different platforms are different, and the symbols displayed on each platform are white or black. As for the background colors of buttons, they are various, showing different shades of blue. It is worth noting that Google platform displays an orange background box, while OpenMoji and HTC platform simply depict the symbol itself, without extra background box.
