The phone is quiet. Is the receiver broken?

If the voice of the mobile phone is very low, it is suggested that:

1. Some mobile phones have noise reduction function, so it is recommended to turn off noise reduction-click the menu button-call setting during the call.

2. If the phone doesn't support noise reduction function or doesn't work after shutdown, it is recommended to shut down and restart.

3. Observe whether there is a deep voice when you speak in other places.

If the problem still exists, please take the purchase invoice, maintenance card and machine to the Samsung service center, and the professional after-sales engineer will help you test it.
