What if the voice of Huawei's mobile phone becomes smaller? I can't even adjust it. What should I do?

Check whether the speaker of the mobile phone is blocked. Please remove the blocking object. For example, when holding a mobile phone on a horizontal screen, fingers will block the bottom speaker (some mobile phone speakers are on the back, even if they are used in bed), and unofficial standard protective cases may also cause the speakers to be blocked.

Please check whether a Bluetooth device is connected and whether the sound comes from a Bluetooth device. It is recommended to turn off the Bluetooth switch and check it. It is recommended to change the sound source to observe whether the sound of the external sound is normal (it is recommended to use the system ringtone test).

Third-party applications (such as WeChat). ) Set the audio system to call status. If it is not restored, the audio channels will be confused, music will be emitted from the receiver, and there will be no sound in the speaker. Please restart your phone for recovery.

If the mobile phone can't play music or the ringtone is small and noisy after a period of use, it may be caused by the blockage of the dust-proof net of the speaker. Inadvertently touching water, drinks, oil stains, dust and other impurities during use will cause the dust screen to be blocked for a long time, resulting in low speaker sound. If dirt is found in the speaker hole, you can gently brush down the speaker hole at the bottom of the phone with a toothbrush or other small brush to try to remove impurities such as dust.

If the above methods cannot be solved, please back up important data and bring the purchase invoice to Huawei Customer Service Center for testing.
