How to turn off HD in the upper right corner of Huawei mobile phone

Hello, the high-definition icon is displayed in the status bar of the mobile phone screen, which means that the VoLTE high-definition voice function is turned on, so it is not necessary to turn it off. The method for turning off Huawei's mobile phone is as follows:

The user opens the settings of the mobile phone desktop, and then clicks Wireless and Network.

Enter the wireless and network interface, and then click Mobile Network.

Enter the mobile network interface and close the VoLTE HD call.
