The media volume of my OPPO A57 phone and the volume in the settings are turned on, but there is still no sound on the phone?
If the phone has a sound or something, it must be a setup problem.
See if the corresponding permissions are enabled in the settings of mobile phone-privacy authorization.
If it is still silent, please back up the data and restore the factory settings of the mobile phone (Settings-System "More"-Restore the factory settings, please do not check "Clear Completely") or try to upgrade to the latest version.
