Hi, Here is my problem: When I play sounds using my headphones (which I tested and work fine), some frequencies are very quiet, while others are amplified. I had this problem in android 2.2, just appeared out of nowhere, it was quite severe. I recently updated to android 2.3 which improved it, but the problem is still there. Strangely also when I use speakers there doesn't seem to be a problem. But if it was only hardware, why would it improve with update? Thanks in advance for your help!
