Ok I have been using my Navigon GPS occasionally and sometimes when the spoken directions are played though the speaker, it's so soft I can barely hear it. So I thought it was just the app. But now, I was just using my phone texting people and all of a sudden the sound became very faint. I can barely hear it. I then went to the iPod app to listen to some music through the speakers and I still can barely hear it. I reset the phone and now everything is working again. Is this normal? Is anyone else having this problem? Can a software update fix this?
