About 3 days ago, my phone stopped working properly during calls. I can hear everyone else, but nobody can hear me. Phone is not rooted. No no, the phone is not muted. Checked that first. Have restarted the phone and checked my general settings more than once; not finding any applicable settings our anything askew. Do I need to give in and hard re-boot / reset the phone? Or take it in to a Verizon store?
