Just wanted to post for the community, to help others who might be in the same situation.
Purchased the new S7 and immediately started having problems with people hearing me, constantly complaining I'm breaking up. No issues with the Droid Turbo prior to this, or the string of iPhones before that.
Verizon sent me a new phone, still have the same problem. I activated the voice over wi-fi feature, and will give it some time to see if this has a positive result. I talk on the phone very little, but when I do... "Can you hear me now? Can you hear me now? Can you hear me now?"
So far I have been very disappointed with this S7, and have like $644 to pay it off before I can get something else.
