How to turn off HD calling?

If you don't want to use the HD voice calling function, you can turn it off according to the following steps:

Step 1: Open Settings

Locate the "Settings" application on the phone's main screen, and then click Enter.

Step 2: Enter the call settings.

Find the Call option in the settings menu, and then click Enter.

Step 3: Turn off the HD call.

On the call settings page, find the "HD Voice" option and turn it off.

The above steps may be different in different mobile phone brands and models. If you can't find the relevant options in the settings, you can try to find the relevant instructions in the user manual or mobile phone official website.

After turning off the HD call function, your voice call will return to normal sound quality, but the call quality will not be significantly affected. If you encounter poor call quality in use, you can try to adjust the signal strength or network connection status to improve the call quality.
