Oppo mobile phone WeChat voice is small, how to turn it up?

The volume of the mobile phone automatically decreases. Please refer to the following methods for troubleshooting:

1. When the power of the mobile phone is low due to the power saving mode, the playback volume can be automatically lowered to avoid rapid power consumption, and the power saving mode can be turned off.

2. If conditions permit, it is recommended to replace the headphones for comparison.

3. There is something wrong with the mobile phone software version. It is recommended to update to the latest official version or refresh the system.

Frequent automatic volume reduction of mobile phones can't solve it. Please back up your mobile phone data (phone number, SMS, etc.). ), bring the mobile phone invoice and warranty card to the local OPPO official service center to help you check and handle it.
