1. If only the receiver is silent, it is recommended that you enter the service APP for receiver detection; If the detection is normal, it is recommended that you change other audio sources to check whether the playback is normal; If it is abnormal, I suggest you clean the handset area with a soft brush to see if it can be improved.

2. If only the speaker is silent, it may be that the audio channel is chaotic, resulting in the speaker being silent. It is recommended that you restart the device to try. If it has not improved, I suggest you enter the service APP to test the speaker. If the test is normal, I suggest you change other audio sources to see if the playback is normal. If an abnormality is detected, it is recommended that you clean the speaker area of the mobile phone with a soft brush to see if it can be improved.

3. If there is no sound when the receiver and speaker play, the receiver and speaker will not be damaged at the same time under normal circumstances, which may be a system problem. It is recommended that you restart the device and try again. If the problem does not improve, it is recommended that you back up important data in advance (third-party applications such as QQ and WeChat need to be backed up separately) and try to upgrade to the latest version.

If you still haven't solved your problem, please contact Huawei's customer service hotline (950800), or back up your data in advance (third-party applications such as QQ and WeChat need to be backed up separately), and bring relevant purchase vouchers to the nearby Huawei customer service center for more help.
