Verizon LTE just quit. Can anyone help diagnose?

Hey everyone...Yesterday, on my stock, 4.0.4 GNex, I noticed I was getting terrible 3G speeds, and no 4G data whatsoever (even though the 4G signal existed). I thought maybe there was a temporary outage, but no dice...VZW support said there were no issues. Today, the issues still remain, and I have no idea what the problem could be. I took some screen shots, so if anyone could offer some advice, I'd really appreciate it. I'd love to try and resolve this myself instead of bringing it to some of the inept VZW techs at the local store. I'm located in Western NY and there is normally a great 4G signal here.
I can post screenshots once I am allowed since I'm a newbie here.
THANKS!
EDIT: I should add, I've experienced the 4G dropping to 3G for a while, and I know this is an ongoing issue with GNex users, but this is completely different.

Another case, same awnser, considering what you said, the device is running the latest official release, and it seems 4g never works at all: return it and get a new one, probably has a bad radio.
If we can get a NYC vzw user as yourself who doesnt have the issues you're describing, i think that would kill it as faulty hardware.

Meaning the radio just went bad? I've had this since launch day and never experienced a problem until yesterday. Also, I'm far from NYC, so if anyone in Western NY (Rochester/Buffalo area) has the same issue, let me know please.

Well, you said you have a stock phone and it doesn't sound like yourself have made any changes to cause this. So, what is it that you want to do? Flash the radio firmware? Root the phone and try different ROMs? Go through all this so in the end you take it to the store anyway? If your description of the problem is accurate, then it does sound like you have a hardware issue. Just take it in and deal with the inept VZW techs.

No I didn't want to do any of the things you listed. I was asking if anyone here could help me diagnose the problem, in other words, see if there's any way to prove it's a hardware issue. I wasn't sure if there were any applications I could get to run diagnostics checks.

If you never experienced these issues before, yes.
I would eliminate a few things (simcard, check another 4g capable phone, side by side, see if it works fine) first and do some testing.

It ended up being the SIM card. They replaced it, and instantly the 4G worked again.

Galaxy S3 in midtown NYC and I've been having the same issue for the last day and a half....

Not receiving incoming calls. Big problem!!

Having a very strange problem with my S3. I've noticed it at home more than anywhere else but basically what happens is that if someone calls me, the phone doesn't ring on my end but I do get a voicemail notification after they've left a message. Then when I talk to them, they tell me that on their end my phone rang once or twice and then went straight to voicemail. And my phone doesn't show any missed calls so obviously, my phone never detected that there was an incoming call.
BTW, it doesn't happen all the time. Sometimes the calls come in just fine.
I've checked my signal strength and it's always between 3 and 5 bars. I've missed more calls than I can count because of this. Some of them were important calls.
And I don't have any problem making outgoing calls or using the data connection for anything.
Any idea what's going on?

Is it just certain contacts? You may have them set to go directly to voicemail by accident. I can't find where the list is in the phone though ahah, I can see how to add them to reject list though.
EDIT: Found it go to dial-pad and hit menu and then call settings and you will see call rejection see if you have anyone in there.

Nope, has nothing to do with who's calling. Sometimes a call from the same person will come through but ten minutes earlier it didn't.

Ive had similar problems in the past. Turned out the phone signal was going up and down. When it was up, calls came through. And down, well duh. Either way, try a new radio. Maybe it'll hold a signal better. I've heard people complaining about H1, but cant say either way myself. Just a suggestion.

My baseband version is UCLG1.
btw, I never had this problem with my iphone 3GS which I had for almost 3 years.
I have to say that even though on paper the S3 blows the iphone out of the water, for pure functionality without problems, the iphone is definitely way ahead of the S3. I'm pretty much stuck with it for the next two years but I have a feeling that if things stay more or less the same in the cellphone market, I'll probably be switching back to iphones after my contract is up. The S3 is very cool but I've just had way too many problems with it that I never had with my iphone. My iphone just..........worked. With my S3 calls don't come through, I'm constantly having to force stop apps so my battery doesn't drain all the time (and even then, half the time the battery drains like crazy no matter what), the visual voicemail is sketchy as hell and doesn't work right half the time, the data connection even when it shows a strong LTE signal is often very slow and times out a lot, and a bunch of other misc. annoyances that I never had with the iphone. I wouldn't say I'm sorry that I bought the phone because I wanted to try out the latest and greatest but when my friends and coworkers have asked me about it, I've been telling them they'll be better of waiting for the iphone 5. Sorry to vent but overall, after having it for almost two months, I've concluded that I'm very disappointed with this phone. Sure, I can do things with it that I couldn't do with the iphone but f*ck me, at least with the iphone I could do basic sh!t like receive phone calls and check my email without the connection timing out all the time.

All of the issues you listed are not really S3 specific because I have had none of them and have had my phone since release. Apart from the video voicemail which I can't comment on because I have never used.

I've had my I747 since release in June and not experienced any of these issues. Over the years with Blackberrys and the Galaxies I found most problems result from variances in the network. Signal strength, carrier software and even where the phone is in the house. I dislike much about the iPhone (I do have a 4th gen iPod) and much prefer the openness of the Android OS and NO iTunes. Hope things with S3 get better for you.

Still having the problem. It seems to happen most often when I have LTE enabled. I disabled it using the method mentioned in another thread where you remove the sim then enter a code which takes you to the menu where you can choose what to use.
When I had LTE disabled, it didn't seem to miss as many calls. But when LTE is on, I miss a crapload of calls. I'd leave LTE off but for some reason it keeps re-enabling itself every few days so it's turning into a massive pain in the ass.
Any suggestions?

I have the same issue as you, but I'm on Wind Mobile. This issue happens intermittently anywhere between 1 to 2 days, my phone will stop being able to receive calls. It's very frustrating and Samsung is really no help. After two attempts on trying to "repair" my phone, they have failed each time. The only thing they did was they ran a "RF Test" and everything passed, they said. So they re-flash my phone with the same ROM - again and again.. I told them, "This is my second time sending it in, and you guys are redo'ing the same steps as the first repair. You don't need to be a rocket scientist to know this, but wouldn't you think when you send me back the phone - the issue is still going to be there?!" ... And sure enough, when I got the phone back, I was still unable to receive calls..
So I took matters into my own hands - I flashed it with a older release stock rom and I tested it for 2 weeks, and it was able to receive calls. When I flashed with the earlier release, it also flashed the baseband. Either way, I should not be prevented from using the up to date software! This is a Samsung issue but if you ever tried dealing with them over the phone, it's painful. They said they would send me a REFURB replacement - (believe me, I tried fighting for a brand new phone, since I paid for a brand new phone and this issue came straight out of the box - it's not even my fault to begin with!) it's been 3 weeks and I still don't see any phone replacement nor did I receive any mails from Samsung.
Btw, Galaxy S3 is the phone I have.
If you discover a permanent fix for this issue, please let me know. I've been searching but no luck.
Thanks!

UPDATE: it's been over a month and I still don't see any phone replacement nor did I receive any mails from Samsung. So I called Samsung today after a month and 2 weeks. They said my replacement have been cancelled. First they said it's approved and requested me to send in my receipt for the phone. I had done the the very moment I hung up the phone from when they told me my replacement was approved (that was over a month ago). They want me to sent it in again to Samsung so they can "test". This is just ridiculous and getting out of hand. Does ANYONE have a fix for this????
Other forums are saying this is a wide spread issue...

are u missing imei, or just the problem you descibe... try flashing the latest modem... maybe yell at it while it flashes...

Nope, just having the issue I described... IMEI is exist and is valid.

There's some newer modems out you could try but it still sounds like hardware...

Sorry for the late entry here but I'm also having the issue. aftershocks, and anyone else having this issue, open battery stats - what does your "mobile network signal" bar look like? Mine is mostly tan except for when I make calls, which then it goes green. I also have an HTC One X (AT&T model) and the bar's mostly green on the HOX.
I've flashed back to the original modem (UCLEM) to see if that helps and I'll move forward from there if not. UCDLK3 was the modem I was originally on when I noticed the missed calls. Here's the thread with radios: http://forum.xda-developers.com/showthread.php?t=1831898.

Wifi Calling Hit or Miss?

Hey everyone, I have a question about T-Mobile Wifi Calling feature. When it works, it is really great but sometimes when I answer the phone either I can't hear them or the caller can't hear me but I can hear them. My Wifi signal is really good but why does this happen? It seems like a pretty common problem and when I searched for solution, there were many but none that really works 100%.
Is there any remedy for this issue?

Yea I have the same exact problem. It's really annoying.

I'm seeing the same issues myself. Hopefully the update with multi-window will address this. I remember my Wifi calling being much more reliable on my Galaxy S from 2 years ago.

Agreed. and wifi calling on my wife's Sensation works flawlessly all the time. Sad thing is I absolutely need it at home. no cell coverage at all.

my s3 and my n2 used to do that but I have the dual router and when I switched from G to N signal the issue was solved.

I've got a Netgear N router that is only a few months old. Still have issues

=( that's pretty disappointing, I guess we all have to wait till T-Mobile fixes it. I was really depending on this feature since I get no service indoor. I can't help but to feel regret switching from ATT...

Am I suppose to set the router certain way to get this working 100%? I went to T Mobile store today and I only made fool out myself. When it was connected to store Wifi, I just couldn't recreate the issue but as soon as I get home it goes all wrong!

Have you logged into your tmo account online and set your 911 address? This seems to have made a huge improvement for my wife's phone but also somewhat on mine from the looks of it. Still not 100% but at least it works most of the time.

yeah, i had to put my address there first to get the Wifi-Calling feature going. Doesn't seem to be much of different on my part though
So many problems with Wifi-Calling feature...
- One way Audio (either caller can't hear me or I can't hear them)
- Text/MMS not coming in or out
- Phone Calls doesn't go through, phone doesn't even ring... when it does ring and I pick up, phone freezes at the answering screen!
WTF! so unreliable... what a mistake switching to T-Mobile was. AT&T was over charging the heck out of me but at least I had no service problems, I'm not sure if cheaper plan is worth going through this.

for some reason my wife's s3 has the same IP as my HP wireless printer.

Was having the same problems on my N2. I've since switched to the N band, but I haven't re-enabled WiFi calling as I am a bit gunshy, especially since I am taking a lot of job calls at the moment.

WIFI calling is truely a hit or miss... sometimes it works great and other times nobody can call me .. they go right to voicemail.
I really hope they figure this out ... wifi calling is soo important to have.

Only real solution is to turn off the Wi-Fi calling feature for now. It's pretty much a hit or miss if it will work on a daily basis.

The problem is that this may be a Samsung phone problem, so nothing a tmobile tech can help you with currently. As others have mentioned, using older phones or other brand of smartphones seems to work with Wi-Fi calling. Most problems were reported from using a Samsung Galaxy s3/Galaxy note 2.

as comforting as it is to hear someone else is experiencing it outside of my 4 walls, its sad to know that its not as frequent as mine guess an exchange is in order

Strangely, I have no issues at all. In fact, it's had some of the best reception of any phone I've had in a very very long time.
"Alright alright, hey hun, I'm in the Elevator and I'm about to reach floor 4 so the calls gonna cut out! I'll call you in a couple minutes when I'm out........ uh...... hello? Oh, you're still there. Well that was embarrassing."

Yes we are both experiencing it. I verified the issue with a test call from both our devices from multiple locations throughout the state. And, well, just from everyday use. I'm able to complete small tasks while I wait for the phone to connect. Like put my jacket and shoes on or climb mt everest.

Ok. Seems highly unlikely to have 2 defective units but guess it is possible.

I haven't noticed any issues on my phone yet. Also the article says it's pretty widespread, but I haven't really seen any complaints on this forum, and folks here can get pretty nit-picky. So, I don't want to say it isn't a problem for some folks, but I very much question it being widespread as the article suggests.

I've been having the issue since taking up a new contract. I figured it was the new sim. But, yes I've definitely been getting it.
Also, been missing heaps of calls. Just getting voicemails come through
Edit: Turns out im missing heaps of messages too. Just put my sim into my old phone and getting abused for not responding.

We thought it was our carrier, but it does appear to be the phone's fault. I'm glad its getting some attention and will RMA just to be safe. My phone works just fine, but my wife's is TRASH.

I have not experienced any of these issues with my Pixel 3 XL. I have been on AT&T since they were Cellular One.

Im on verizon prepaid and i dont have call quality issues, well kimda usually they disconnect as soon as i answer. Thats my only call issue
