Was on the phone for 10min before it started happening. I've tried calling multiple people since, and they all have told me that it sounds like I'm in a wind tunnel or that I sound very faint. I've tried on wi-fi calling and with wi-fi off. My volume is all the way up and my bluetooth is off. Phone has had no problems so far, but some articles I've read online say it might be a Verizon issue rather than an Apple issue.
Can anyone help me out?
