This only happens with certain people.
If I call my girlfriend, she can't hear me at all (or sometimes I can't hear her). but if she call me back, we can hear eachother just fine.
She's on Verizon, and I used to be a verizon customer.
This used to happen on my old phone so I got a replacement. It still happens.
I went to the Sprint store they told me to call network support.
I called support they told me to go to the store.
can anyone help?
my phone is an Optimus S
