I would suggest going back to HTC if thats a deal breaker. They have been promising advanced calling since as they (verizon and sony) said the first quarter. As it's now almost September and they no longer even list this phone for sale on their sight, it really is looking like it like any updates for lollipop or stagefright won't be happening. I dislike saying so as I own the phone too, but all I seen from verizon in the way of support, is about as good as their communication about it. Little to none at all.
