As on topic. Need urgent help it. When I set Samsung Galaxy S Ringtone, notification and mediatone to 13-15. The sound is really loud. But always, after a short usage of the phone. The sound of my phone dropped until very soft. I did not change any ringtone, notification and mediatone setting. Mediaplayer sound, ringtone and notification is extreme soft even at MAX. May I know what is the problem? Or there is a setting that auto reduce my phone sound? But my setting for all sound is set to MAX. Pls someone over here help! Thank you very much.
