What should I do if there is no sound in the Xiaomi 2 S receiver? How can this problem be solved?

1. Here we try to restore the mobile phone to the factory, click "system settings"> "backup and reset" on the mobile phone desktop to enter, as shown in the figure.

2. After opening the "backup and reset settings" window on the mobile phone, we will "restore factory settings" in the personal data column"

3. Click restore factory settings. The Xiaomi system's restore factory settings are personalized. You can choose whether to delete the application, that is, whether the currently installed application on the mobile phone is deleted. This is customized when the factory settings are restored. After setting, click "reset mobile phone" below"

4. After the factory is restored, we can try making a call. If not, try again.

5. After the above, if there are still problems, most of them are the cause of hardware. At this time, contact Xiaomi customer service and ensure the repair.

I will remind you that if it is a hardware problem, we only need to repair it. There is also a temporary way for us to try using headphones to see if the handset is broken, however, the headset can be used in this way.
