I just bought my first smartphone about two months ago. With help, I just upgraded the applications to 4.5. Before this, when my phone rang or I used the media, it was nice and loud. Blackberries are known for their audio. I was able to hear it from the other side of the house. And the phone wasnt even on loud, it was set on normal. For some reason after the upgrade, it is sooooo low.

Yes..i changed the phone profile from normal to loud and no difference.
Yes..I did go under phone profiles, advanced, phone and had the volume on high.

Now I am missing calls when its in my school bag, or in the other room. When im listening to my playlist or watching a movie, can barely enjoy it because its so low :-(

Does anybody have any idea what happened or any suggestions?
