Hi... I just got my 4S yesterday after switching from a droid. I love it, but i am having a problem with voice calls. No one can hear me unless i put the speaker on when talking. I have tried switching settings, etc. I was on the phone with verizon support and they say the phone is defective and they will send me a new one. Since it is a new phone they really don't know much about it so i'm not sure if it defective or a setting is wrong. A new phone is going to take 2 weeks since they are back ordered Ugghh! Does anyone have any advice on some setting that may be incorrect? Any advice would be appreciated.
