Thanks for the reply, but I did state in my issue above that my daughter and her husband have VERIZON for their service and theirs does it just as much, if not more than ours. So switching carriers doesn't do any good if we are dealing with two different carriers, but yet the same iPhone 12 series. Kind of sounds like it is the phone and not two different carriers. If it was just one, I would agree, but it is two different carriers.I tend to think it's a Spectrum issue. You say the phones are Spectrum through other carrier services, like Verizon. No one else I know is having issues like that with their iPhones. The fact it's more than one iPhone, leads me to believe it's NOT an iPhone issue. It's something else. Maybe switch to a better carrier system.
Again, thanks for the reply
