@PaddyCree There are a few things you may wish to check here-
- Ensure that the volume on your device has been set to the highest level during a voice call. You can also try tapping on the speaker to see if this improves the call volume.
During a voice call, press the volume button located on the left side of your device, and then tap on the drop-down arrow to open the volume settings.
Tap and drag the Call volume bar to the end to maximize the Call volume settings.
- Check to see if the microphone and receiver are blocked/dirty. If it is blocked or dirty, gently brush it off using a dry toothbrush or a brush. After you have cleaned your device, test your device again to see if there is sound.
