Why is there no sound when the ringtone and buttons of Apple 6plus are turned on?

Hone6 6 6 mute button is a switch. Turn it to the side near the front of the screen, which belongs to the silent off mode, that is, the normal mode.

Turn to the back direction to turn on the mute mode, and there will be no sound when taking pictures.

After the iPhone6 turns on the mute button, there is not only no sound when taking pictures, but also incoming calls and text messages. Will also become dumb.

The solution is as follows:

This may be because the option to turn off all sounds is set. I suggest you turn off all sounds through phone settings-My Devices-Accessibility and uncheck it.

Set-Sound-Volume and try to turn up the volume.

If it is invalid, please back up the data (contacts, multimedia files, etc.). ) and restore the phone to the factory settings.
