[Verizon Samsung Galaxy S6] Juan Q:
HD Voice feature needs to be turned on, but don't!

Hey guys I've talked about this in different forums and sites, I'll copy and paste it here and hopefully it will help you understand why you can't place calls using the 4G LTE without having the Advance calling feature turned on under the Verizon network.

"Verizon is aware of the HD voice/video feature being the culprit of the dropped calls, they are blaming Samsung for not pushing an update to correct the problem. Meanwhile Samsung has said that the feature is a Verizon software. I was told by their tech support that it has been reported that there's a 50% dropped call increase using the galaxy S6 while having the HD voice/video feature on, this was 2 weeks ago. The agent said they have a search tool like Google search, this is internal and that's where he found this information.

You can not make calls and surf the web without the HD voice/video feature on, but turning this feature off will STOP THE DROPPED calls. Verizon's software side for galaxy S6 does not allow you to make calls on the 4G LTE network when the HD voice/video feature off, instead is shows 1x.

I have been in touch with Verizon wireless tech support for the last 3 weeks now, this past week Verizon has been sending me texts to update me on the progress of my ticket. I've had Samsung tech support in conference call with Verizon tech support; during this call that lasted more than 3 hours Verizon admitted that it wasn't a Samsung problem but Verizon's. As soon as the tech from Samsung hanged up the call because we were told that I would have to call their engineering department to further assist us. Before the Samsung tech agent hung up the call we had asked if I could make calls using the 4G LTE and was told to hold up while he researched this question. As soon as the Samsung tech agent left the conference call the Verizon tech answered no, and proceeded to make a complete 360 on answers he gave prior to the Samsung agent leaving the call, saying that the problem was not a Verizon but Samsung problem, even though moments before he said that it wasn't a Samsung problem to me and the Samsung tech support agent but Verizon's. I was also advised by the Verizon tech agent that if I wanted to, I could JAIL BRAKE my Galaxy S6 and download a software to disable the HD voice/video feature without losing the 4G LTE but that it probably still won't work properly. I told this agent that I've never jail broken a device and don't plan on because this is clearly a Verizon feature not working properly.

Not even 5 minutes after ending the call with Verizon's tech support, a supervisor from Verizon called me to tell me again that this is a Samsung issue not Verizon, he said that Samsung needs to push a SW version update to fix the problem with the HD voice calls dropping. He asked what I wanted, I said to get the Galaxy S5 and return this phone, but that I was told by 2 different stores (Rockville Centre NY, and Merrick NY both in Long Island) that if I wanted to return this phone or exchange for a different one I would be charged a 40% restocking fee even though I was within my 14 days. I was told by the tech before the supervisor called that it was at each store's discretion whether they charged you a restocking fee or not. I was told to consider this mater resolved by the supervisor, that they will get in touch with the store so I can return the phone and if in fact there are any fees I would be refunded in some sort of credit; but all I've received all of last week is text messages letting me know they are still working on my ticket."
