What's wrong with Huawei's low voice?

If the sound of media files such as music is low:

1. Please make sure the sound is turned down. It is suggested to press the volume up button and try to solve the problem by raising the sound.

2. Please check whether the mobile phone speaker is blocked, and please remove the blockage. For example, if you hold a mobile phone on a horizontal screen and your fingers block the speaker at the bottom (some mobile phone speakers are on the back, which is the same if you use them in bed), unofficial standard protective cases may also cause the speaker to be blocked.

3. If you confirm whether a Bluetooth device is connected, a sound will be emitted from the Bluetooth device. It is recommended to turn off the Bluetooth switch for inspection.

4. It is recommended to change the sound source for observation (it is recommended to use the system ringtone test).

5. Some third-party applications set the audio system to call status. If it is not restored, the audio channel will be confused, the receiver will make music, and the speaker will have no sound. Please restart the phone to restore.

6. If the above methods can't be solved, please back up the important data and take the purchase invoice to the outlet for testing.

The voice is very low:

1. If the other party can't hear you, please try to get close to the microphone.

2. In places with weak signals or areas with strong interference, the call is intermittent, which is a normal phenomenon caused by network problems. Please try to use it in an environment with normal signal.

Please use the standard wired earphone or turn on the speaker to see if there is any improvement. If there is improvement, there may be something wrong with the microphone and receiver. Please take the shopping receipt to the store for inspection.
