What to do when your phone's speaker has no sound or weak sound?
I found that the phone has many types of volume., such as ringtones, alarm sounds, call sounds, third-party application sounds, and so on.
If you have this situation, you can refer to:
1、Restart, this is the universal method；
2、Check whether the speaker is blocked，You may have using a non-standard protective case；
3、Check if the speaker is clogged, or use a non-standard protective case;
4、Check whether it is an issue with the audio source. Play a system ringtone to see whether the issue still occurs；
5、After a phone has been used for a period of time, the speaker filter may become blocked. If your phone has been in contact with water, beverages, oil, or dust, its filter may be blocked by foreign objects. In this case, it is recommended that you use a small, soft brush to gently clean the speaker filter.
If the issue persists, back up your data and take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance.
