Check whether there are any foreign objects blocking the sound output holes of the microphone, speaker, and receiver (if your phone emits sound directly from the display, skip this step.)

• If the audio output is normal, proceed to the next step.

Check whether the signal of the phone is normal

If the signal is abnormal, the call quality will be affected. In this case, refer to The phone has an unstable signal.

If you use a third-party app to make calls (such as WeChat and QQ), make sure that the signal reception is good.

Disable or enable VoLTE and check whether the issue is resolved

The quality of VoLTE calls will be affected if your area is not fully covered by the VoLTE network or if there are compatibility issues. This issue can be resolved by enabling or disabling the VoLTE feature. (If you cannot find the switch for VoLTE, it means that VoLTE is enabled on your phone by default.)

Reset all the settings and try again

For details about the method and precautions, refer to Reset all settings.
