Fixed verizon call quality

I have fixed the issue after numerous calls to LG and Verizon wireless. I am so disappointed with both companies. The vocoder software is faulty. from dialpad press ##PROGRAM980 and SEND to place call, the service code is 000000 then you goto Voice SO select each tab and change from Wild Card to 13 QCELP. Restart phone and its fixed

Just did this and work perfectly now! It was the only thing bothering me about this phone. Thank you!

Cool. What exactly does this fix? I haven't noticed call issues. I changed it anyway. Does this improve call quality or what?

What is voice so?

Wildcard lets it switch between voice codecs. QCELP 13 is the old 13Kbs voice codec replaced with EVRC which was replaced with SMV inn turn replaced with CDMA2000 for 4G networks(4GV successor of 3GGP2 type[Qcelp-SMV] codecs). 4GV is dynamically prioritized per network. EVRC-B is half and quartet speed. We do not have any later options, just QCELP and EVRC. QCELP is uncompressed 13Kbs, EVRC 8 is compressed with but with higher quality codec at 8Kbs. Default is EVRC8 home and roaming, page is wildcard to auto select best for the particular network. The only thing it may fix is using a tower that is overloaded with bad compression. Note that forcing the specification can cause more overload to the 3G signal, in turn, just making things worse for everyone. If I'm not mistaken, the way towers and plans are set up, a 4GV codec would cause using voice com to eat into data plan. I do not think most carriers are set up to sniff the data type to determine if it is indeed voice data, hence we don't have awesome voice quality that we are more than capable of having. Hope this helps.

Does it still work when on 3g connection?

It will. We have no 4G codecs. Unless you have problem with the default codec on your towers, this will not help, only hinder quality. I have no issues with default codec or quality at and around my location. Baltimore to D.C..

When I tried this the settings didn't survive a reboot.

Mine stuck even after a reboot

I tried this on mine (Malladus) and wife's (stock), both (..phones) are fine after reboots and all.
Just can't yet confirm any differences.

QCELP-13 worked perfectly
EVRC 8k gave me some of the digital clipping type noise
EVRC-B works good and has minimal clipping
So the QCELP seemed to worked best over all.
Also, no issues with the settings surviving a reboot.

I'm test-driving this, too. Somebody at Android Central forum reported a possible impact on battery life. Anybody seeing anything like that?

this worked for me. The call quality still isn't the best but I am not getting that annoying noise anymore.

I definitely have seen a sizable increase in nlpWakelock since I made this change but I didn't think it could be related... Could it be?

Just tried this on my Verizon device, sound is much improved.

Unable to make calls while connected to 4G(LTE)

Hi guys,
I've been a visitor of the forums over many years now. Learned quite a bit reading all these great posts.
I'm constantly changing phones but always return to Samsung. Now I'm moving from the Note 5 to the S7E.
I just picked up the S7E today and I'm very impressed. Phone looks great and is very fast. A couple of hours playing with the phone I noticed a big problem. I'm unable to make calls when my phone is connected to LTE. When I attempt to call someone it doesn't drop to 3G to place the call. Also my Internet stops working. I can't force 3G/2G and my only option is to reboot the phone. Once I reboot, I'm able to force 3G/2G and I'm able to make calls and Internet works before and after calls. But in this mode I'm stuck without LTE.
Do you think this is faulty hardware? Or should a software update fix this?
Many thanks to XDA community!

Who is your carrier and which exact variant (SM-G935T, ...935V, etc.) of the device do you have?
Are you in the U.S. or somewhere else?
If this is a carrier-specific device being used on its intended carrier's network, then this problem is something their support people could (and should) be able to help you with.
There aren't enough specifics in your post for anyone to have a reasonable shot at helping with this issue.
Also, I just noticed you posted in the general discussion forum. This post is really asking for help and would be a better fit for the Q&A forum.

Hi,
I bought the international version (SM-G935F). It does not have any carrier branding.
I bought it in Switzerland and I'm using it in Switzerland with a Swiss carrier.
Mods, please move this thread to the appropriate section if it doesn't belong here.
Thanks!

I also had an S7 Edge with calling issues (dropped every call after a few seconds, possibly trying to switch from 4G to 3G or from 3G to 2G). It turns out it was defective and the replacement works as intended.

Just did a hard reset now.
Was able to make one call. When I tried a second time, same issue. Reboot seems to allow me to make an initial call but then same issue again.
Will take it back tomorrow and hope they have a replacement in stock.

The Feature you are talking about is Voice over LTE! Here in germany this is only anabled in the branded Provider Firmwares like from Vodafone or t-mobile germany. If you have an unbranded Device like i have G635F than VOLTE is not working cause its locked! Not Sure how this works with swiss Providers. In germany VOLTE only is working with Company branded Firmware! And to be honest i am rally worried about that cause i will never use branding Firmwares.

Update: took the s7 edge back to the store and of course the phone worked perfectly. There was nothing they could do as the phone worked fine and we were able to make many test calls.
Phone worked fine during the day but when I got home the problem started again. After some testing, it seems the problem only occurs when connected to 4G+/LTE+/carrier aggregation.
Couldn't place any calls at home this morning but at work where I only get 4G everything works perfectly. Very strange.
In Switzerland I don't think we have VoLTE. When we place calls the phone drops to 3G but for some reason it's not happening when connected to 4G+.
Ill do some more testing today to see if I can find any 4G+ areas near work to test.

Same issue
Hi,
I just got my new S7 Edge (SM-935F) and I think I have the exact same problem. When I'm in the city where I live (Morges, Switzerland), I can't make or receive any call while on 4G but data works. Switching to 2G allows me to make or receive call though.
Then, when in a different city (50km away), everything works as it should be (call and data on 4G). Did a factory reset and it also didn't change a thing.
The guy from my carrier's shop (Sunrise) told me that there was a known issue with 4G calls on the S7 and S7 Edge in different cities (mostly in the canton Valais). I've also been told that Samsung is working on an update to fix it so returning the phone to get a new one would be useless. Did he tell when that would probably be fixed ? Of course not..
I hope someone find a fix soon
Looks like the antenna gate from the iphone 4 but seriously how can something like that still happen

Hi,
Looks like we have exactly the same problem. I work in Geneva but live in Gland. Today I tested my phone in Geneva and it worked perfectly everywhere while in 4G or 4G+. As soon as I arrived home in Gland I'm unable to make calls so I have to force 3G/2G in order to receive and make calls.
By the way I also have sunrise as a carrier.
Good to know that it's a known problem and that they are working on a fix. It's very annoying... Hope they fix it soon!

S7 Edge & HD Voice, does yours work?

I only had my s7 edge for about a week but my HD voice doesn't work at all oddly.
My s5 it replaced worked fine. The people I talk to can call others and HD shows but me it doesn't nor does mine.
I just not sure if that big update broke it maybe or something else so wanted to see if others are working?
I don't have a sprint store near I can go play with them at :/

Talking Sprint to Sprint. So your S7 Edge running latest update, the HD is working on?
Do you know what model phones you've talked to on the other end?
I'm calling someone with an LG G5. They can call someone else with an LG G5 and it works but talking to me it doesn't.
Not sure if it's some device compatibility issue (which would be new), my phone, my account or what.
My S5 never had issues so trying to figure out what the deal is.
I even traveled to a different part of town to get on another tower to test, still no joy on S7 Edge

Amazes me that all the S7 owners and no one could check this :/
I bet if this was about root people would be all over it lol.
That said, solved the problem.
It is related to WiFi calling. Turning it off alone isn't enough to enable HD (despite on older phones just turning off WiFi calling it worked fine.).
On this phone you have to actually turn it on and go in and "deactivate" it which also unprovisions the account. After that HD started working again.
I personally consider this a SW bug but who knows. I also think it's dumb they can't do HD while on a wifi call. It has tons more BW available yet you can't do an better codec?? Every other provider only gives you HD when you doing VOIP but sprint takes it away lol.

This may be old news too, but Google Voice cannot be activated either for HD voice to work. That said, I haven't had it work for me yet either on the S7 Edge, and I don't have Google Voice anymore.

In WiFi calling, turn it on. Menu drop-down in upper corner has it. Follow the prompts.

I still can't get HD Voice calls to initiate unless I am using Wi-Fi calling. Anyone else having this issue?

Now that you mention it, my HD voice hasn't been working either. I did deactivate it, I didn't really use it anyway and did a radio reset. Will have to test again see if it works. I haven't tried a call since deactivation of it yet

In this context (Sprint) what's the difference between HD calling & WiFi calling? I'd naively assumed they were one and the same...
Sent from my SM-G935P using XDA-Developers mobile app

HD voice is a higher quality call. It sounds much better and filters out background noise. WiFi calling is a way for your phone to use your wifi network to make phone calls. WiFi calling simply replaces the network with wifi and can be used for standard calls or HD voice calls.
My problem is that hd voice calls never seem to work unless I'm on wifi calling.

Me too en4cer, that's why I thought they were the same thing... The "HD" icon only shows up when Wifi calling is turned on. In what other situations *should* it show up? Sprint to Sprint calls over mobile network? Other carriers? Depending on the other party's phone & coverage at the time of the call?

Yes, it *should work when making Sprint to Sprint calls and both callers are in LTE coverage. It's not a WiFi feature, it's a Sprint network feature that also works on WiFi calling. I have not been able to get a single call to go to HD VOICE while on the LTE network. Frustrating!

This is so dumb

Sprint has issues provisioning the S7, so much like the iPhone, if you enable Wifi Calling, You can not currently use HD Calling. This also means you can not use Push To Talk.

My HD Voice has been working fine between to other Sprint callers that support it. I disabled wi-fi calling service, I don't really use it anyway. Also LTE coverage doesn't matter, none of Sprint's calls are routed over LTE yet, even HD voice uses CDMA network.

Calling fix for verizon (I can make calls again)

BLUF:
If your Verizon account does NOT have HD Voice enabled and the essential phone has "Enhanced 4G LTE Mode" enabled (which is a default setting) you may not be able to make/receive phone calls.
I had an older phone running a lineage fork that did NOT support HD Voice. For whatever reason that also means it isn't enabled on my Verizon account. It doesn't cost anything extra and isn't plan specific but until you enable on a phone (says VZW Tech) the setting stays off.
When I put my SIM into the new Essential phone I could make calls but it would NOT find a new tower. IF i was driving any distance I had to reboot the phone completely to get data or make calls.
As of a few days ago my data was always working (LTE+) but suddenly I could not make or receive any calls. Again, texting, internet, etc. was fine. (yes wifi was off to test this =)
I was on with VZW support trying to fix this when my essential trouble ticket was answered with:
Given that you are getting the LTE+ icon already, can you try this step and see if it helps:
Go to Settings -> More -> Cellular Networks
Disable "Enhanced 4G LTE Mode"
Make a phone call
Return to the Settings menu and re-enable Enhanced 4G LTE Mode

VZW said give it a try lets see. With it "off" I could suddenly make calls. With it back on I couldn't again.
VZW said I bet that's what we call "HD Voice" and I see its not enabled on your phone. He enabled it. I rebooted. Everything works again with that setting on or off.
I emailed this back to essential just to let them know what I did with VZW and got reply:
My understanding was "HD voice" was enabled on all smartphone accounts with Verizon, but I will add that as a step to check in the future.

Click to collapse
I've been troubleshooting this with VZW and Essential for a while so very happy to find fix. I also went out and got a brand new SIM but that also didn't help. Both new and old sim worked in old phone fine but in essential no luck.
I had at first though unlocking bootloader / rooting had done something . I wiped and reflashed this thing 4 times yesterday trying different things to no avail.
I know some other Verizon uses were having weird issues so wanted to share.
I'll prolly never get so lucky with tech support synergy again in my life... but at least this one time they were quickly helpful.
MODs: If this should be in "guides" instead please move or I can repost

Phone no longer ringing when the network is 4G LTE

Using the phones on Sprint.
Since three weeks or so, while on LTE, the incoming voice calls are going directly to voice mail.
Sprint looked at it and changed the Network to 3G and now getting a ring for the incoming calls.
Basically, I am forced to run the phones on 3G service.
Need to go to a service center (which is very far for me) to have the phone looked at.
Anyone facing similar issue?
PS: 2 of the 3 PH-1 phones I have, are having the issue.

Google have updated the dialer recently several times, could it be a bug that shows on Sprint, or do you have spam settings on, which I know has caught other people out. Check/play with spam settings in her dialer app.
(other areas I might check (if not dialer or network). I assume all phones were working before correctly, right? Are they different sims or the same sim in different phones? New sims, ie not old one you have cut down hat are old spec. Do lte settings match on different phones?)

Same issue. Did you get it fixed?

I also have this problem on Sprint.
Sometimes restarting the phone fixes the issue, sometimes it doesn't.
Between this and no longer being able to use Google Voice without using a separate number, I think it's time for me to bail on Sprint.

My wife had this issue a bit back. Only happened when the phone was using VoLTE (verified by a debug menu, *#*#4636#*#*, showing both voice/text and data marked as LTE).
Fix was to disable the Enhanced 4G LTE communications option, which forced the phone too fallback to nonVoLTE while still using LTE for data. Again confirmed using the phone information menu which showed voice as 1xRTT and data as LTE.
Hope this help and that we can get a better fix soon.

Didn't work for me either but I figured it out... what I had to do is change a setting under Google Voice in Settings under the tab CALLS change to "Use carrier only" and I did have to turn VoLTE off. I left the Preferred network type as LTE. Phone is working well now, with T-mobile and Google Voice I have been testing it all morning.
