[Nexus 5 Q&A, Help & Troubleshooting] Syndrome666:
Yup, that sounds like the rest of us on at&t around NYC and metro area. By the way, switching to ART seems to slightly fix the issue, but being on ART for a week now, i can say that the dripped call problem still persists, just a bit less frequently than on dalvik runtime. If nothing helps even after lollipop official ota update, I'm switching to t mobile. How's the service on the N5 with t mobile by the way? Is it worth the jump from at&t?
[Nexus 5 Q&A, Help & Troubleshooting] simms22:
ill tell you, but dont take it as including everyone.. i live in southern brooklyn, work in queens. i never ever get dropped calls in my area(s). near home my data speeds are around 65mbps download, 23mbps upload. and near work my data is much slower, 25mbps download and 10mbps upload. around nyc, anywhere but the belt parkway, i see great signal. on the belt parkway(edge of nyc and the ocean) i see a few places with a very lousy signal.
[Nexus 5 Q&A, Help & Troubleshooting] Syndrome666:
Wow, the fastest I've ever clocked at&t's lte was [MENTION=4632091]50mb[/MENTION]ps down and 14mbps up, and this isnt very common, at least not in Staten island. My contract ends the 19th, yay! So I'm going to give T-Mobile a shot. Seriously considering the switch, especially if at&t doesn't fix this compatibility with lte call drops by the end of my contract.
[Nexus 5 Q&A, Help & Troubleshooting] simms22:
if you are mostly around the city, youll be fine. its those way out in the country places that tmobile sucks with.

Thankfully, its the block i live on with the best speeds :)
[Nexus 5 Q&A, Help & Troubleshooting] exorz:
The service on TMO is decent. Data speeds are good and I didn't have this drop call problem which is a huge plus. Coverage is almost the same but ATT does penetrate a litte bit more it seems. It's really the price that the difference. Right now I'm on a family plan that works out better for me.
[Nexus 5 Q&A, Help & Troubleshooting] nsiti:
I have the same exact problem discussed here, since about 2 weeks while making calls on the LTE setting.

I'm with AT&T using an Samsung Galaxy S4 with a Google Play Edition Rom (Kangakat).

I live in NYC where each and every call gets dropped within 10 seconds.

I traveled to New Orleans last week, and no problems at all.

Hopefully this helps in some way.
[Nexus 5 Q&A, Help & Troubleshooting] VOLTAGEROCK:
Please call AT&T and report it!! I did on Thursday last week and I'm waiting for a response.

Everyone else here, report this problem please. We all need to.

I'm having the same issue on a Bell Canada S4, running a GPE ROM. Thanks for the tip of switching to 3g, been going nuts trying to resolve.
[Nexus 5 Q&A, Help & Troubleshooting] rav4kar:
We are having similar call drops issues on S4 GPE too, either with new or old modem firmwares. So it's safe to assume this is something wrong at at&t's voice to data issues or other way too. Only thing we can do is report the issue to them though they do mine the dropped call data and analyze the issues. :)

Funny thing is that I'm far away from US. Practically half a globe away at Malaysia. Recently I too have been getting weird call issues. The call would just go totally silent at random. I cannot hear the person speaking on the other end. If I call the person again, I can hear the other person fine. I have no idea if its Lollipop or its my carrier. I think switching back to KK radios made zero difference to me.

I think its definitely unrelated to AT&T/D820 current issue though.

Just that I feel the same way as you guys when your call drops or cuts out.
[Nexus 5 Q&A, Help & Troubleshooting] greeneyez15o:
At&t said to get a microcell, and that no one has called to file a complaint

Just got a text from at&t and it says: AT&T Free Msg: The investigation for your case has been completed. If you have additional questions please call 1-877-971-5016.

So I called and the guy said it's a Nexus 5 problem. He said to call Google. And he said that they have received many complaints recently about this problem.

So now I have no idea what to do next.

Just thought I would let you guys know what I heard.

they won't tell you this, tho..

the ONLY reason they won't charge for VOlte now, is because they, really can't, not when legacy voice services / channels are still abundant, ims wifi & voice over lte are an *option* now, w/o charge,

but, just, wait, until *everything's* via that single data pipe..

their business model is shrinking real fast -

I asked the guy why this started two weeks ago and why all of my friends in California are not experiencing this problem. Believe me I had this guy in a corner until I just gave up because I couldn't spend any more time making him look like a fool as I had to get back to work.

Something is seriously wrong with AT&T as we are only experiencing this in New York New Jersey and Pennsylvania so I am completely baffled. I hope you guys get some other answers from what I got.

[Nexus 5 Q&A, Help & Troubleshooting] DonDerham:
Got my daughters each a Nexus 5 last year for use on AT&T. The girl in Tennessee reports no problems with her phone. The lass in New York City started having problems Saturday with dropped calls.

I called Google. Its representative asked upfront "AT&T, east coast, right?" Then he told me that it's an AT&T issue that AT&T is aware of and working to resolve.

Then I called AT&T. AT&T's technician told me that she saw no Nexus 5 call issues in her system, but did see a Nexus 5 data connectivity anomaly. She suggested going to a store and swapping out the SIM. The SIM version from December, 2013 is version 27. The current SIM is version 28. No harm in doing that. Will just need to wrestle the phone out of the kid's possession to do so.
[Nexus 5 Q&A, Help & Troubleshooting] VOLTAGEROCK:
Thanks. I will give that a try.

Does anyone know how they program new sim cards? I have a custom ROM but that shouldn't matter correct?

Regardless, Google is saying it's an AT&T problem and AT&T is saying it's a Google problem!! This is going to be fun.... :)

Nah. My daughter's phone is stock unrooted. The ROM shouldn't matter. The radio matters.

In a couple of days, Google will push an update for this phone to Android 5. That'll have an updated radio. This might fix the problem. Or it could make it worse.

I made a call yesterday from my office in Midtown Manhattan and it worked fine, but then I remembered that my phone was connected to wifi so LTE was not active.

I don't make many phone calls so can't really test it, I will turn off wifi later and give the wife a phone call to see if it happens again. Hopefully I don't freak out the wife with a phone call because we only call when there is something wrong... lol

[Nexus 5 Q&A, Help & Troubleshooting] TechGuyInNYC:
Just signed up to the XDA-Dev site just so I could post on this thread as we are experiencing this identical behavior with several Google Nexus 5 devices:

- Bone stock Nexus 5

- AT&T

- Work and live in/around NYC

- Dropped inbound/outbound calls after 5-10 seconds

- Started happening ~2 weeks ago

- AT&T tech support said they had no record of this issue

We have tried:

1. Wiping to factory settings

2. Trying a brand-new, out of the box Nexus 5

3. Getting a new SIM card

4. Reprovisioning the mobile account voice/data

Since I found this thread, I will instruct my coworkers to try forcing 3G to see if that alleviates the problem, but finding this thread was like stumbling upon proof that aliens exist. I BELIEVE... that AT&T is monkeying around with their network that is causing this exact behavior. And, as so many have mentioned before, these same coworkers with N5's have been working just fine for months prior to ~2 weeks ago.

Went out for my afternoon coffee and was walking on Park Ave and called my office phone to test out. Call dropped after two or three rings, funny thing, I was across the street from an AT&T store. I went in and the first thing they said was to swap out the sim, but they were kinda busy and I did not feel like waiting.

This is just fantastic, I left Sprint for AT&T because of their crap network rollout and now I have to deal with AT&T having network issues.

Same issue on GS3

I am having the same issue on a GS3 AT&T just west of Philadelphia. However, setting 3G as the preferred method does not seem to work for me. Neither does connecting to wifi as some others mentioned. The only way to reliably make and receive calls seems to be to disable mobile data altogether. It took a while to come across this post. Before that I flashed 4 other roms only to find out its a network issue.
[Nexus 5 Q&A, Help & Troubleshooting] slicetwo:
Does it happen on teh stock ROM too?
[Nexus 5 Q&A, Help & Troubleshooting] rbalfury:
I can confirm that this is definitely affecting Philly Area, NJ and NY as I just took a day trip their from Long Island.

Spent two hours with a rep in a store and on the phone with them. They have a case number open and will call me back on Thursday.

Also just took advantage of the Nexus phone warranty exchange...I can confirm it still has the same issue with the exchanged unit not being able to make calls with LTE on.

One thing I did find odd is that on my ATT account homepage after I have logged in it shows my phone as the LG 821 when I know my phone is the N.A. version LG 820.

So I called to tell them about it and they said they switched it to the 820 however it still says LG 821 as my device.

Can u guys check out what yours say when u log into at&ts website?

I know the 4g bands are different on the two devices.

It's a long shot but maybe it has something to do with the issue we are all experiencing

Turning LTE off doesn't help as the phone still fails to connect to the voice network. Data works perfectly but Voice typically shows Out of Service no matter if I'm on 2G, 3G, 4G.

I switched back to my Galaxy S3 stock rom just to see if that made a difference and it did. I can make calls when connected to LTE and not have them drop. It still switches over to 3g/H+, though it then loses data totally for a minute or two. What this implies to me is that it's a weird mix between AOSP and AT&T.

Hi Gents,

Thought you guys might like to know that you need a special sim card from at&t to allow calls on LTE now, specificly voLTE.

You can tell by non-Volte sims

UICC-F. - 9th and 10th digit being 26 or lower

UICC-G - 9th and 10th Digit being 27 or higher

Simular Issue

I've been looking through this thread hoping it was something close to what's happening to me.

N5 w/ Stock 4.4.4

I am on T-Mobile and every single call i make it will drop the call at full signal after around 5 mins. I even have time to remove the phone from my ear and see the signal bars disappear and reappear at full strength. I see that ATT fixed OP's issues so im going to wait on Lollipop and hope that these issues don't persist.

Same problem

I am having the same issue in NYC as well on my Nexus 5 with AT&T running build 4.4.4. I logged a complaint with Google as well as AT&T. Google refused to acknowledge the issue and gave idiotic suggestions to check the data plan or change my internet connection. When i finally lost it and lambasted them for these stupid suggestions they told me to keep my phone on 3G. I haven't had any issues since being on 3G but still feel cheated...:(

This suddenly started happening since last week. I travel to NYC for work every week and haven't experienced anything of this sort in Charlotte where i live.
[Nexus 5 Q&A, Help & Troubleshooting] rbalfury:
OK so I just received a call that my case has been closed with a call back number for At&t support.

So when I called the rep on the phone told me that yes they are aware of the problem and that they are working with Google to fix it via an update.

She said that we would be receiving a software update soon to address the issue but couldn't tell me an exact date.

I asked if she meant it was going to be part of the new version of android that is coming out.

She told me she wasn't sure.

Maybe this is the reason why android 5.0 update was delayed for us???

Isn't it supposed to be rolling out via OTA on the 12th?

is there a verified source for this information? I turned off LTE on my wife's Nexus 5 so she could actually use her phone as a phone as she usually tends to 90% of the time. hpsa & + are still plenty fast for streaming music and using maps for gps nav.

sometimes I do speed tests on at&t to compare LTE vs hpsa+ and find little difference. I do a lot of public wifi access too while I'm out and about. LTE is almost necessary for real time games like Ingress.

Hope android L gets out to auto update or at least a flash-able version I get snag straight from google.

As for my AT&T G3 variant, no dropped calls since purchase.
