Ok a couple weeks ago I noticed a hardware problem in my phone. It would not make any sounds at all. I checked all settings and everything was fine. It finally took me slapping the speaker against my hand for it to finally work. Well now its doing something completely different, at first I thought I was imagining things but my text messages had no sound notification, well I laid my phone on the table and sent a txt message, email, and then called it. All worked except the txt message notification...... So now I am confused at why this is happening. Is there any apps out on the market that could cause such a thing to happen?? Thanks in advance!
