I work about 100 yards from the store referenced in the post above. I will be going there this afternoon to confirm the issue on the display phones.
I made my 3rd call to verizon last night. Ended up speaking to a consumer advocate. He openly admitted to the issue and proceeded to tell me that even though they are required to tell customers not to turn 4g off he told me that if that is the only way to get my phone to function that I can turn off 4g using the LTE off app.
He said that he does not think I have a hardware issue but is sending me a CLNR. If the same issue occurs with the second phone he told me I might be able to switch to another phone.
