Talking to Verizon support today trying to figure out why Advanced Calling wasn't working, and they straight up said that it appeared that I was rooted. I feigned ignorance, but I thought it was very odd that they knew this.

The My Verizon Mobile is the one that tells them. If you deny it root when it asks, it knows you have root. If you didn't have root I think there would be no reply to it's asking for root.
Ah, is that why my advanced calling isn't working? Annoying.
I need to call them for my Advanced Calling as well (as it's complete horse s**t that I need to enable that so my phone doesn't drop from 4G to 1X) but I've never been prompted by My Verizon about root access...
There's a system property you can find with "getprop" called "vzw.os.rooted". I tried changing it in build.prop, but it didn't work. There's also a partition called persistent with a file /persistent/rct.cfg detailing some not allowed system behavior. There are things that detect root since it's pretty noticable and readable to everything at /system/xbin/su. An app that communicates to the internet could easily transmit that information. This is one of the many reasons I have a firewall (AFWall+). I installed it pretty soon after I got root, but one of the many vzw bloatware apps probably got the info out. Guess what, I don't give a s***.
FWIW, I had a lot of difficulty trying to activate Advanced Calling on software 610B. I worked with Tech Support for a week, no luck.
I finally updated to 611A as a last resort, and it suddenly worked. So if you're having trouble getting AC enabled, and you're on 610B, you may need to update your software version.

Isn't 11A the upgraded version of 11B? I know it sounds backwards, but we had to KDZ that to root phone.
Before I rooted my advanced calling worked. After root when I make calls it drops to 1x. Don't really care as I don't browse the internet on my phone while on a call (99% of the time).
Still, it's pretty dumb of Verizon. Then again they do more than their fair share of dumb corporate related ****.
Mine works and I'm rooted with no firewall or protection to block them knowing.

AFAIK, there is no 11B.
Just 610B (original, what shipped on my G4), and 611A (OTA update, which I needed to use in order to properly activate AC).
I am not rooted.
Advanced Calling also works fine for me on rooted 11A. However, I recently disabled it because ACR will not record calls with it turned on.

This is the same problem I'm having. I had to KDZ to 11A when I rooted, and I haven't been able to get it to work since.

For those of us who haven't fully been following the root discussions, what does that mean, that you KDZ'd to 11A? You had 610B, you used KDZ to put on a 611A image (not taking the OTA to 611A, so you kept the 610B bootloader), then rooted that?
Did AC work before root, presumably on 610B?
After what I went through to finally get AC working, I would really hate for root to break that

AC worked perfectly for me on 10B, and after I rooted (KDZing to 11A) it will no longer activate. I tried toubleshooting with VZW, and none of the things they did on their end fixed it. The only suggestion they had was factory resetting, but I haven't tried that yet.
I'm sorry to hear that.
There seems to be some mysterious magic to Verizon's Advanced Calling. In the span of a week, after a bunch of work on their end, Verizon was unable to fix mine, they resorted to telling me to exchange the phone. I had already done a factory reset, at their suggestion, which did not change anything. Then after the OTA to 611A, it suddenly worked, and it seemed this was a surprise to them, as well as to me.
Having issues with AC after rooting would seem worse, they could potentially blame any issues on root.
Why problems with AC can't be figured out, and then fixed, is kind of disconcerting. I guess maybe there's a reason the phone calls it Advanced Calling 1.0.
AC was working for me also and then it stopped. I was already on 11a before rooting. If you have the verizon app called name and id on your phone ac will not work. Once I froze that app in tibu it went back to working. I'm not for certain but I don't think that app was on my phone before root so it may have been included in the rooted img file.

What else do you have frozen? I have that frozen too, and it's still the same.
I'm not rooted (maybe that's the difference), but I noticed today that I have Caller Name ID on my phone. And last time I tried it, AC was working. Just FWIW.

Hello -- I was trying out a MDM in the office on my G3, and after disassociating my device with it, I started getting FCs on "vzwavsservice". Mainly when the phone boots up. I can't really find any information online as to what this actually does. I have just disabled it. I have not noticed anything different or malfunctioning on my G3.
Anyone have any ideas what it could be? Obviously it is some sort of VZ Addon...But wondering what its functionality or reasoning is.
Thanks in advance.

I'll be honest. After I posted this, and I froze/disabled this "Service"...I haven't noticed anything not working or acting funny. I would say this is safe to disable. It is likely some type of Verizon add-on.
If you do disable it and see something act up, let me know. Would love to know what it does lol. But for now -- Mine remains disabled. :good:

Does that give you an error after logging in?

I started getting this today too. Most of my Verizon stuff is frozen however. Wonder if VZW is pushing an OTA today. Those of us getting it, are we all rooted?
I just got this force close today after updating some apps on the play store. Posting in the Verizon LG G3 section might get more responces.

You can disable the VZWAVSService without being rooted. Which likely means it is really really pointless.
I get it sometimes on stock unrooted, but also always when I have stuck a T-Mobile or ATT sim in the Verizon LG G3.
VZWAVSService caused by Google+ Update
The VZWAVSService error ceased when I went to application manager and uninstalled the Google+ updates.
Once the updates were uninstalled, my mobile hotspot and USB tether functions returned.
It seems that this service is an address verification process. This explains why, when my phone checked my subscription status for Mobile Hotspot and Tethering service, the functions did not activate.

My hotspot service works with VZWAVSService disabled. I do not think that hotspot and this app are related since I had also disabled this service on my Galaxy S3 for months and the hotspot service still worked the entire time.
I have a Verizon LG G3. I just uninstalled the Google+ updates and reverted back to an "Original Version" to see if that goofy message will cease to continue. I am rooted and i have Wifi Tether Router installed. I used Stump Root to root the device.

Just freeze the app, you can even do it in the stock settings. Vzwavservice-Verizon's anti virus software that McAfee makes and it is strait garbage.
The 11c update fixed this issue?
After flashing beans 11c and using if for a while I realized that I had not re-frozen vzwavsservice. It isn't closing on boot anymore. I believe Verizon fixed this issue in the latest software release.
I took the 11A update so that I could root my phone, and since then I've noticed that I no longer have simultaneous voice and data. It worked perfectly before, but now it just goes to the 1x and has no connectivity during calls. I also cannot send an MMS when connected to wifi. It will eventually time out and fail, but if I disconnect wifi it will send instantly. Any troubleshooting things I can do to fix these issues?
Apparently Advanced Calling isn't activated, and it won't stay activated when I select it. Anything to do to fix that?

Yours may not be the same symptoms as the other user (they sound closer to my symptoms when still running 610B). But it may be worth checking.
If you're using Verizon's Message+, it can send texts over WiFi. Perhaps that feature could be causing trouble, if it doesn't get along well with your WiFi somehow?

You have to disable ABP, if you straight uninstall it it leaves the host files. I am not to sure where it stores the backed up host files but you can try to reinstall ABP enable blocking, disable blocking then uninstall. It may require a reboot after disabling. Not sure if this will help but its worth a shot.
Good evening all.
Has anyone with a G4 on VZW noticed issues with apps on wifi since the latest firmware update? I've called Verizon and been on the phone with them for HOURS to no avail.
The only time wifi works normally is in safe mode. When I'm on wifi, most apps just aren't functional at all. We thought it was some app in particular so we reset the phone and the issue persists. The only thing tech support suggests is giving me another refurbished G4 which will get us nowhere as the new G4 will just be running the same firmware.
This is problematic for me as I work in and out of different buildings on any given day. These buildings don't always provide the best reception. I clamored with Verizon for a different, comparable phone. I spoke with LG and their solution is me sending the phone in with the turnaround time being 5-7 business day which is also problematic as I don't have another phone to use. Verizon refuses to acknowledge it's an "issue" because it's not "wide spread". A quick search revealed that this problem is not limited to just me.
I've exhausted my options. I do not want to spend hours on the phone with Verizon again. I do not want to speak with LG for the same phone again. I simply want a working phone. This is the 3rd G4 that I've had that does not work. The 3rd G4 in almost as many months. What are my options here?
tl;dr This is my 3rd LG G4 that doesn't work and the latest firmware update broke the wifi functionality. Verizon refuses to acknowledge the issue and will only give me the same phone, not a comparable phone. What are my options?"
Yup. Since the update. Wifi on my phone is lagging horrendously.

Same problem here (and also with friends who have both VZW and the G4). This exact issue popped up on the LG G3, also after an update. Infuriating that they broke another otherwise good phone. The workaround is to install an app called DNSet. It sets the DNS to Google's, which fixes it.

Yeah I'm having the same issue. It's maddening!! Nothing comes through unless I manually sync or have to open the app to get it to sync. How is this an acceptable software update for verizon - who usually requires a high level of quality control on software updates??
The Update broke Notifications over WiFi. It has something to do with IPv6. Verizon PULLED the update because this is a major problem.
Either call Verizon and have them replace the phone (you will get the older firmware 11A back on it)
OR
The fix is to download DDNS or something (It is a VPN service) that routes ALL internet traffic over IPv4 connections. I forget the specific name, but it is being heavily discussed in the "VERIZON UPDATE" forum in the General section.

You can fix this issue without root by using the app DNSet from the Google Play store. You hit 1 button (the one and only button), and it turns off IPv6, and problem solved.

3rd worst mistake of my life... (don't ask)
LG G3 D851 was working just fine until I "upgraded" to 6.0 Marshmallow.
After Android 6.0 update OTA via T-Mobile, phone calls were terminating quickly and then got to the point where they didn't work at all. I used Google Voice almost exclusively, but problems were occurring for T-Mobile direct calls, too.
The phone call issue seemed to grow, and the update then ruined my battery from boot looping.
At my wits end, I did a hard reset (btw, is there any way to save app preferences and restore them) and it seemed to work ok on AC power ONLY. If I unplugged it, it went right back into boot loop, even though my battery was showing 100%. I know it was my battery, because I tried a friend's battery and it worked ok.
So I slowly installed more apps, and finally got a new battery, so I could use it without being plugged into AC. Things seemed ok for a couple days, then today the same phone call problems and freezing were back again!
Occurred after updating eBay app, but have no idea if that was the culprit, because I have all apps set to update automatically on WiFi (probably not a smart idea).
Did the Google Voice trick (remove app from phone, then go to PC and remove real number from GV list on PC, then go back to phone, reinstall GV app and have GV find my real T-Mobile number automatically and add the number from the handset), but 'unable to complete phone call problem' is back on GV or the T-Mobile network.
Super frustrated and angry. Nice effing "update!" Everything is stock, not even rooted...
Any known app conflicts on D851 running Marshmallow?? Ideas?
I'm thinking another hard reset, but would love to save all my app preferences to restore them (doesn't seem to work on LG PC Suite, which is what I used for backup last time).
TIA.

@healthylaff, probably don't want to hear this but...
If you were previously rooted, the #1 rule is, was, and always will be Never Accept OTAs! For any number of reasons, some of which you've experienced.
You can go back to LP or start off again with MM since it looks like you'll be starting from scratch.
Main irk I have with MM is the change in storage paths. That breaks or hampers a few things. Enough that I can't/won't use MM as my primary environment. Still continue to test/run them though. Anyway...

it keeps telling me i have it, but can not activate it.
i just kdz-d back to stock rom. advanced calling is still not working.
update. after making several phone calls and restarting the phone a few times, the advanced calling came back on stock.
update 2. after making sure i had advanced calling on stock, rooted it with low effort root and the advanced calling stayed. it was the root img from this thread. http://forum.xda-developers.com/verizon-g4/general/vs986-rooteddebloated-t3256814/page58.
i am going to try to flash the pure lg on top of it.
update 3. i did a dd of pure lg (low effort method) on top of the other rooted image and maintained advanced calling. it's a bit cumbersome, but the only way i could get it to work.
update 4. more problems. advanced calling is turned on but there is no data during the call. something is still screwed up.
update 5. flashed back to the previous rooted image, and i have data while calling as well as video. the problem is with the pure lg. also, lg backup didn't work on that.
Kdz back to stock (13b).
Set your phone up like usual.
Get advanced calling activated and make a test call to make sure it's working.
I install all of my apps and set everything up just like I want it.
Then extract your own system image, inject root, then flash the rooted system image. It should keep advanced calling functioning. Your using your own system.img not someone elses. That's why it works. Its worked for me and everyone I know that's tried it.
If you don't know how follow this thread:

I went to the Verizon site, removed advanced calling, waited a few minutes, then added it back again. It's been working for me ever since.

My old G4 bootlooped on me so I'm in process of setting up my new refurb. I believe LGDMSClient must not be blocked for you to enable hd voice. This will also enable ota's, but you should be able to disable it again right away.
That seemed to do the trick for me anyway. I was adding and removing hd voice on the website to no avail until I unblocked LGDMSClient, and then bang, the hd voice option was there.
I had Advanced Calling on my original rooted G4 but after it bootlooped, I couldn't figure out how to activate it on my replacement until today. I can confirm that what finally worked was going to the VZW website to deactivate AC, unfreeze System Updates (aka LGDMSClient), reboot, activate AC on my phone, reboot. I have the latest My VZW installed and RootCloaked.

That just seems like such a bizarre/obscure feature. Maybe noise suppression isn't 'available' in advanced calling, and that's why?
I'll give that a shot. I'm gonna put the G4 up onto 27c -- but I'm not sure if I can KDZ straight from 13b to 27c. I don't want to wipe everything out -- so I figured I'd try to find out the answer first.
I had the same issue. What worked for me was first make sure that you have advanced calling activated on your account. Then I kdz'd back to stock. I went through the normal setup. I verified that I still had advanced calling on my account. I went into settings and clicked on advanced settings and then clicked on activate and when it was greyed out I factory reset the phone. When I went through all the normal setup again advanced calling was working.
