There is no sound on Ping An Securities' mobile phone.

The most common ones are that the volume is not turned on and the mobile phone is set to vibrate.

1, many people often forget to modify it after setting it to vibrate, but the sound of the mobile phone on the pillow is so low that it can't be heard. I have met this point several times, and it is because of this that I am late.

2. If the mobile phone speaker is broken, you need to get it to the mobile phone repair shop for repair. Generally speaking, it is best to go back to the factory for maintenance, not in a small shop to prevent the other party from replacing parts.

3. The mobile phone software is faulty and the audio driver is damaged. In a similar situation, you can try to download the driver from the relevant mobile phone official website. Of course, if it can't be solved, you need to go to the factory for maintenance.
