It only vibrates when I am called. The silent red dot button is NOT on. No red showing. The volume is turned up completely. When someone calls and I put them on speaker, it does not work. I don't know what else to check. I just got this phone yesterday. Please help!
Well, after I restored my phone it finally started making noises again. However, my phone asked me to from "back up from icloud/itunes/computer;" Once I did that, it is back to how it was before, silent not ringing. I will try again and see.
I have tried to restore it again. It did not work even before backing up everything. I went to AT&T. They were not able to help. They made sure all the settings were correct and told me to restore it which I have done twice. So on to an Apple Store I will go.Thanks @ckuan for trying to help!
