A small speaker icon often pops up in the upper left corner of my phone. How can I cancel it?

1. First, we open the Huawei phone, and then use our fingers to pull down the interface.

2. At this time, some menus will appear above, and then click the fold button.

3. At this time, we find the location of the "floating navigation", and then click to close the floating button.

4. At this time, the floating navigation button turns gray, which means that the floating navigation button is turned off.

5. At this time, when we return to the desktop, we can see that the small speaker disappears, indicating that the floating button is turned off.
