My wife got her S22 two weeks ago and Thursday (two days ago) all group texting stopped and now the phone heats up and gets very hot. We went to two local AT&T stores and they were absolutely useless. We were told that we would have to pay a 55 dollar restocking for a defective phone.. We've tried everything to get her group texts to work and nothing worked. She needs group texting for her work and for our daughter's school. This is ridiculous.. Why would we have to pay a restocking fee for a phone that doesn't work?
