As on topic. Need urgent help. Got this issue since the first day of Galaxy S. My ringtone, noficitation and mediatone is very soft. Even i set it to MAX. But after a reboot. The sound of the phone suddenly become very loud. But after a short usage. Like 5-10mins. The Tone become very low again. FYI, I didn't change any tone setting. It is still remaining at max. Is there any reason why, or there is some kind of power save for Tone?
