Why don't other mobile phones have the mute switch like Apple?

There are three possible situations: iphone has no sound, but there is sound when listening to music or playing games, and the volume on the home screen is turned off. Solution: Switch to the home screen and press the volume button on the side of the iphone, and you can see that the volume has increased. If it still doesn't work, please check the top button next to it to see if the red area is displayed. If there is, slide it up. Case 2: The iphone is silent except for incoming calls. When listening to music or playing games, the mute button of iphone is usually pressed by mistake. Solution: Check whether the buttons on the top of the iphone side display red areas. If there is, just slide up. If it still doesn't work, it may be that the speaker function is damaged. It is recommended to go to a professional Apple repair center to find customer service. Scenario 3: The user is in do not disturb mode. Solution: Slide the screen from the bottom, open the control center and click the "do not disturb mode" icon to close it. I hope it helps.
