What's wrong with the silence of Apple's mobile phone information?

There is a mute button on the left side of the front of Apple's mobile phone, which can control the current ringtone. When you find that there is no prompt tone on your mobile phone, please check whether the mute function is turned on first.

Second, restart the phone.

Please press and hold the "power button" on the top of the Apple phone and press the switch option. Then slide the slider to turn it off, and then press the power button to turn it on.

Third, restore the settings of the mobile phone.

If it is not the function of the mute button, then you can try to restore all the settings of the phone. Open the Settings application on the phone's home screen. Click to open the General option in the settings list, then find the Restore option at the bottom of the general list and click Open. Click and select the "Restore all settings" option in the restore list. Then click the "Restore All Settings" button to start the restore. Restoring all settings will only restore the system settings on the phone. This recovery will not affect the data on the mobile phone, such as photos, videos, music and so on.
