Oppo mobile phone ringtones suddenly become smaller.

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. The mobile phone software version is out of order, so it is recommended to update to the latest official version or refresh the system;

Frequent volume reduction of mobile phones cannot be solved. Please back up your mobile phone data (phone number, SMS, etc.). ), and bring the mobile phone invoice and warranty card to the local customer service center to help you check and handle it.
