Anyone else have the problem with Galaxy S21 Ultra dropping calls, cell working intermittently etc? My wife has been on tech support three times. They ultimately send her to a store and the store tells her the problem is the network and call tech support. The first actually told her to update our plan so we did. Samsung has also troubleshooted the issue and said it is a Verizon problem which I would be skeptical except the Verizon store people say the same thing. We have been with Verizon for 20 years and I’m about ready to leave for a better customer experience. Any ideas? One store person said this is a known issue and they should replace the phone but Verizon tech support won’t do that.
