I have had my s20 ultra since release, needed support to correct it during startup after dropping 2 or 3 of my chats that went on forever, and I never have had decent enough signal to make calls in my house. I had the Note 8, and NO PROBLEMS. It is not a signal issue. Not only has this been happening, but I have to reboot my phone after every single call that will not connect. Anyone else experiencing this? I tried support, but I cannot get a response.
