Pop the SIM card out.

I have LTE set to off for both data and voice and I experience the black out problem on Verizon with my iphone 6 plus.

I just had this happen for the first time today. Worse yet, the other party couldn't hang up, I was in a phone menu that was not set to disconnect on no response. I was stumped at how to recover, then I thought to pull the SIM card - bingo. It at least got my screen back and ended the call.

Checking the VoLTE switch now.

I know this is an old thread, but I have this issue with a 6s. Changed the screen for a customer. As soon as the call is placed, the screen goes black. You can press the home button and the screen lights up for a split second but goes black. You can't end calls, or any other options on the call screen. Took proximity sensor off customers original screen and installed it on new screen and it still immediately goes black. Suggestions?

Thanks.
