The folks hearing their voice bounce back are all on their cell phones vs landlines. I did disable wi fi calling but immediately I could not turn on/off my security cameras once away from the house. I wasn't even on wi fi when this was happening so it made no sense. I was about ready to go to an S-22 but on another post a user of the S-22 was having the same issue. I hated my IPhone I had for work before retiring and prefer to not go back to it but my wife, son and daughter and sister in laws all have one on Verizon and they are not seeing the issue.
