Samsung mobile phone SMS notification voice has been adjusted to the highest, why is it still low?

1. Check whether the third-party software is newly downloaded and installed on the mobile phone. It is possible that the software is incompatible with the mobile phone, so I suggest you try to uninstall it (Settings-Application Manager-Select Download-Uninstall);

2. If it doesn't return to normal, I suggest you back up your mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings (Settings-Reset-Restore Factory Settings);

If the problem still exists, it may be that there is something wrong with the software of the mobile phone system. It is recommended that you take the three-guarantee certificate of your mobile phone and send it to the nearest Samsung service center for testing.
