I bought the HTC Hero recently, and I got this problem ever since. When I speak with someone on the phone, his or her voice is barely hearable. Litteraly, I have to ask the person on the other side to repeat her or himself 2-3 times before I'm actually able to hear her/him. So, long story short: the volume is abnormally low. What I've tried: volume control apps. They're all set at maximum volume. Hard-reset. Didn't help. Anyone with bright ideas?
