iphone 12 call quality problem
We have a new Iphone 12 on Verizon. Call quality degrades quickly (others hear every other word, sound not always clear) even when the caller is stationary. We've called Verizon support - no signal issues in area and have gone through the restart, restore network settings, etc. with no improvement. Iphone XR and 6 in same location do not have these issues. What is the fix?
