Nexus 5 - Mobile Signal Drop - Nexus 5 Q&A, Help & Troubleshooting

Hey guys...
I have a Nexus 5 16GB D821 on Android 7, had another D821 6 months ago on Android Marshmallow...
Well, I noticed that on my both Nexus that often during the day, my mobile signal drop to zero for 4-5 seconds and then it goes again to 50%-60%
I belived it's not a software problem since I had two Nexus with this issue...
Anyone here have this problem with D820 or D821?
Any fix? It's kinda annoying, sometimes it drops to zero exactly when someone try to call me.
My radio version is M8974A-2.0.50.2.30, Kernel Version 3.4.0-gc30602d ([email protected])
Thanks!

I have exactly the same problem with signal. But I have more problem.
For me, if i drive, i lost my lte service and drop to stupid EDGE which is horrible. I cant hear the music from youtube for example. And I know there is coverage because before works with no problem. Maybe Tmobile can help for me with new sim, but its possible, that is hardware fault :/
Im using my kernel, but tested another one, nothing with completely stock too. Strange :/
Try to debugging but not found a solution yet.
Cant wait for Pixel now But I love this phone

Well, I believe it's not a sim card issue since I had two different sim cards (from the same carrier) and still having the same problem...
I'm really starting to think that it's a hardware problem
And I love my Nexus 5, after 3 years still very fast...

I tried one another sim ( with another carrier ), and my phone its not recognized, only works with my sim which is tmobile. But the another one is very old, but working with S4 mini.
Another radio does not help

I have the same issue! always have to reboot and the signal goes away at random moment. terrible

If you type in phone app *#*#4636#*#* and go to phone test after make ping test what is your result?
For me everythings passes only IP ping got fault with this error: fail: ip addr not reachable with all modem. :/
But i have mobile data working at home. Another city i only have edge for example in Budapest which is a joke xD :/

Nexus 5 cell reception issue?

Anyone using a nexus 5 on T-Mobile in the NY city area getting very bad reception I'm not sure if there's an issue with the device or tmobiles service coming from an HTC one that had excellent reception I think there might be something wrong with my device

Are you getting excellent HSPA+ reception, but the phone isn't switching to LTE or connects to LTE, but jumps back to HSPA+?
Go to a T-Mobile store and tell them about your situation (don't chat with them online because that did not fix my situation). The rep that I spoke with called tech support and they did some sort of reset on my account. I also asked for a new SIM and was given that new ISIS SIM. As soon as my phone booted, it was on LTE and stayed on LTE. I was like you, thinking that my device was messed up, but T-Mobile fixed it.
No if you check the discharge chart I posted the phone is just completely loosing service but I haven't tried getting a new Sim yet I'll try that and see if it helps

If every other phone you had before this one had much better service I would suggest getting it replaced with mine if I walked inside just about any building even single story stores and homes it would loose signal

The problems you describe were while using T-Mobile on a Nexus 5? I've only had T-Mobile service about a week now, before that I always used AT&T on samsung android phones (S4, Note II, etc). And service was always very strong on AT&T.

Anecdotally, I'm having terrible reception in NYC as well. At home and in the office, barely one bar, frequently none.
Over the past 2 years on an HTC Sensation 4G, have typically had no reception problems in these same areas - 2-3 bars at all times.

I've had T-Mobile for years and never had connection issues as bad as this so im hoping it was just a faulty device and not the device in general just getting poor reception

sounds like the same issue im having ill update when ever i get my replacement to see if anythings changed
We have the same issue with Nexus 5 with Tmobile in greater NYC metro area. When i tried with my old Samsung mobile there is no issue and it works fine. The problem, I can't make and receive any calls. Most of the callers told me, it goes to voice message after couple of rings. I didn't get even single ring and voice mail message. Frustrating Nexus 5.
My friend and I have the same problem too.
Both 16gb White
What colour of nexus 5 you guys have?
I see some have white, maybe white causes this issue??
Having the same issue as well. I have a 32gb white model and I randomly lose all bars when my friend calls me. It is very random and only happens a few times. Going to go and switch out the SIM from T-Mobile and have them reset my line and see if that fixes the problem.

32GB black with miserable cell reception here, so not a color issue.
Maybe an LTE issue? Might explain why our old devices got better reception, if they were using older gen signals/antennas? Not that we'd want to in the long term, can we disable the LTE services and live off the previous gen, at least to test?

I get lots of complete dead drop outs too, even on Wifi. One moment cruising along, the next I'm disconnected, the next I'm back on. Something is not right with this device.
Hmm I need to also find some time to visit a t-mobile store and check out why my reception just drops and gets spotty all of the sudden sometimes.
I have the 32gb white model. I never get LTE while two of my friends with Nexus 5 that were next to me both got LTE.
I also had my signal drop to 0 in a starbucks before, and I never had that happen with my previous Nexus 4, was frustrating since I couldn't get the promo code for my starbucks reward drink x.x
Ok guys Google is definitely on its game with replacing your your nexus 5 placed my RMA Sunday night got it today and I can report my new phone is working as it should I wouldn't say it gets as good a signal as my one did but a minimal difference that you would expect between two different devices so if your having an issue call up Google tell them you already spoke to T-Mobile about your service issues and they couldn't help you and that your certain its a device issue as a side note their RMA process has you basically buy a new device and send them the old one
Also I had a black 32gb so I don't think the color matters

After my research, When we switch back to 2G (GSM Only) option there is no issue with voice calls but the data speed is very slow as expected. It seems that there is an issue with T-mobile towers LTE/3G/4G for voice calls. Below is the problem with Sprint network, looks like same thing happening for Tmobile.
s4grudotcom - sprint lte connectivity issues due to circuit switched fallback technology.
If you need voice calls high priority like me, give a try to switch GSM only.it shows E network on signal bar.

[Q] Signal drop/No service

Just wondering if any one else gets this, sometimes my signal just drops out and I get no service.
Then it comes back it does not happen all the time, I live in a big city Leeds infact so signal is quite strong.
Just wondering if it could be a fault with the phone?
Thanks
I've noticed it happens to me too.

It is definitely possible.
I'm on AT&T and have the correct APN settings and have called AT&T with my IMEI. I have significantly worse signal than with my HTC One X. I am not comparing bars to bars, but rather where the signal drops completely. In places where I had low signal but still connected I now have nothing.
Straight talk using at&t Sim and notice radio drops..

T-Mobile on stock ROM i had my first signal drops.
I was fine (or at least never noticed them) from the time i got my phone (day one) without any drops here in orlando.
Drove over to Tampa/Venice Beach area this past weekend and noticed some drops. Had about 6 drops according to my battery stats in 2 days. i had good to excellent coverage the entire time except when it would drop comlpetely (outline of signal bars)
would connect in a couple seconds, but i noticed over night, it would drop for a pretty large amount of time (like 10-15 minutes at a time.)
Mmm defo seems like were all having the same issues, wonder what it could be

I had this issue too, and here's how I fixed it:
By default LTE is enabled, meaning the phone will periodically scan for a LTE network. If you're in a big city, you're likely to find one. Your phone will attempt to connect. However, it fails, meaning it will have to rescan the HSPA bands to connect back. That results in a few seconds of no service. Why can't it connect to LTE? Because by default, the APN is not the LTE APN, for Rogers at least. I'd assume AT&T would be the same. You can test this by dialing *#*#4636#*#*, selecting phone info, and selecting LTE only. You'll see that there is no service. I tested this in an area I knew had great LTE coverage, and that led me to the conclusion that it's LTE causing the signal drops.
So how to fix? Simple, just change your APN to the LTE APN for your carried. To do that go to Settings -> More -> Mobile Networks -> Access Point Names. If you're experiencing this issue on Rogers, change the APN field to ltemobile.apn. If you're on another carrier, you'll have to search for their LTE APN configuration.
After doing this your phone should start connecting to LTE again, and you won't get those annoying signal drops.

So yeah the next update will probably fix the issue. It's not so bad in the meantime, Lightflow sill notify you that your nexus has lost signal, and you still get the internet and incoming calls.
We're not alone. Supposedly Google is "aware" of the issue.
i've hcanged my setting from '4g' to '3g' to see if i notice a difference (hopefully will) then when 4g is released or i get a 4g sim, can move it back up
Yes, I'm having issues too. The real problem is the fact that I have a Wilson cell booster in my home (supposed to have up to 5000 square foot range) and my n4 had full bars most everywhere inside. With my n5 It shows 1 to 2 bars if I'm lucky and quite often drops to none! The only way to get full bars Is to stand right under the indoor antenna. Not impressed, and I sure hope this is fixable!

I hate to revive a dead thread, but I was wondering if people were still having problems. Once or twice during the day that I can see I will lose signal for a few seconds only to have it reconnect. Running 4.4.2 so the latest update did nothing to help the problem as far as I can see and I have messed with my APN settings. On AT&T. The Google thread seems to have a lot of different problems on the same thread, and it is a bit unclear if people are still having this problem. This is very annoying for such an otherwise spectacular phone. Thanks and sorry again for reviving the thread... :fingers-crossed:

Appreciate the speedy reply. Hope Google gets on this fast. I also have LTE connection issues which has plagued both this and my original device so I am pretty sure its a radio issue. The phone loves to stay on HSPA+ even when there is a decent LTE connection: it's last in the pack to connect to LTE and first to disconnect when compared to others on AT&T.

My N4 with a combo radio sticks to LTE a tad better than my N5 with stock radio. Sadly, morrislee hasn't fiddled and combo'd N5 radios, and I'm not sure they've been tested and sussed out like the N4 radios. Citing the fact some with issues have flashed all the radios so far with minimal success means we wait for Qualcomm, after Google kicks them in the you know where.

Please Help! Nexus 5 Signal Issue(Not rooted)

I just got my Nexus 5 and I haven't root it yet. I notice that everytime I don't use my phone 5-10 minutes or hours, the signal will be lost and asking to reboot my phone. I can't tell when it's up or not. Sometime I take multiple reboot to get signal back up then it happens again and again. Is there a way to fix this problem without rooting? I don't think it's the Sim Card because I used it on my nexus 4 without any problem. or Just my device isn't good one. Please help!

I didn't root my phone yet, and I'm running 4.4.2 now. It's annoying to keep losing signal and it's back again. Even I have signal, I only have 1 bar compare to my old Nexus 4 has 3 bar or HTC one full bar.
I don't want to root it if its not solve this problem, I will have to return it.
There was an issue on 4.4 where it would randomly give you the "emergency only" message. You would have to turn on airplane mode and then turn it off, or reboot. But people have been saying it was fixed with 4.4.1/4.4.2.

I think it might be overall worse, but luckily I actually didn't see any decrease in signal in my area. I was really worried about it because I already have really bad signal in my house but 4.4.2 doesn't seem to be worse for me.
You guys forget to mention that Google cheaped out on the antenna to cut costs. Best you can do is to flash your carrier's radio over the generic one

I'm sorry, but you're dead wrong. SO much misinformation here. First off, there is no "carrier" or "generic" baseband. There is only one baseband. Second, antenna design requires a lot of engineering to maximize signal efficiency when you're dealing with interference from such things as wifi, nfc, Bluetooth, metal construction in the phone, etc.. I'm not sure what magical material you think that cell antennas should be made of that will solve issues?
I just got off of the phone with Sprint. They show that there is an internal memo on the issue and LG is aware of it. They will be pushing an update as soon as it's ready. Sprint will also be pushing an update for the Airave to help with the issue. The support rep told me that it is an issue where the wifi and LTE radios aren't playing nicely together and causing a conflict. That's why everything seems to work fine when 3G is set as a preferred network.
It's an issue that still hasn't gotten fix as seen here.

The issue seem to be gone after couple days. I checked signal strength app, it shows same even though it shows only 1 bar.

[Q] No signal strength all of a sudden

Hello,
I bought my Nexus 5 on the 11th of December 2013 and it had been working flawlessly ever since. Since last week, I started noticing the occasional signal drop and I'd be out of cell reception but would usually be back up within no time. However, yesterday, out of the blue I'm travelling on the highway and my signal strength disappears never to come back again. I've tried the following:
- Restore old backup (including EFS)
- Went back to stock from PA
- Upgraded to the latest radio
- Took back cover off to see if anything was wrong but found nothing.
- Tried another SIM card
Nothing worked. My SIM card works fine in another phone. Everything else such as WiFi and Bluetooth works flawlessly but I just don't get any reception.
This is very disappointing and I have my fingers crossed hoping someone can help me with this since I didn't plan on getting a new device for at least another year especially after paying $520 USD for my phone here in my country.
Thank you for looking.

Flash stock firmware with fast boot. If its the same, its a carrier issue....call them to see. Or its hardware failure.

Then it is a carrier issue....cause on Telus in Canada....never had an issue with any radio version. ?
telus would have a stronger overall signal but uses AWS band for lte which is different than mobilicitiy 3g aws...
I'm not disagreeing.... Just saying its the carrier....not Google.
See my point?

are you saying mobilicitiy is purposely weakening their cell signal cause they are almost bankrupt ?

Just saying that unless many have the issue with the phone or radio, then its an issue.....if not, it isnt .
So in this case, it leaves hardware or carrier....assuming a stock flash didn't help.
If flashing another radio helps the OP...awesome!! But the new radio does work fine for the mass majority.
Hope it does work for him tho!

Calls made when on LTE keep getting dropped

About 3 out of 5 times when I make a call when I am originally on LTE the phone call drops. I am on AT&T and when I make a call it switches from LTE to H+ then all of a sudden it just completely drops signal and thus the call and about 3 seconds later regains signal. Does anyone know what may be causing this issue or has had this issue? I am on 4.4.4 Stock with Root.
Well dropping calls isn't normal, but dropping from LTE to H+ is. VoLTE isn't really a thing yet. Calls don't work over LTE, so when you make a call it automatically drops to H+. That's normal behavior.
Did this just start happening out of the blue? Or always done that? Make sure you have the correct APN settings. If so try calling your provider and see if there's anything they can do for you.

Sorry forget to mention I knew that was normal for the drop to H+, but yes the signal drop is not. Well it started out of the blue. IS there a thread on here with what should be the correct APN settings? Also my old nexus 5 started to do this before I returned it under warranty for refurbished, then I had a moto G lte for a month worked fine, got a refurbished (due to warranty) and started again.
Here is a graph of my network coverage to show that the signal just drops.

Mine doesn't seem to have any particular count pattern, it happens very randomly, usually when attempting to call someone and once they pickup on their end, my phone would hang up. This happens maybe 40-50%of the time, can't estimate a guess, but i can say that it happens enough to piss me off. I've checked my AT&T APN, which matches to what the carrier has it set, i even went and got my SIM replaced, rebooted in safe mode, gps works, so it's not a third party app causing this. Last resort is factory reset, although I'm almost positive that won't do anything. I'm currently also running android 4.4.4 stock aosp on a 32Gb N5. Device was purchased new in early may 2014, and came with android 4.4.2 preinstalled. The random call drops issue started in early October, a few months well into 4.4.4 update. All I've found online is that i it has something to do with a missing cellular radio, but to be honest, i don't want to mess with those as that may cause further problems. Called Google, and they act like they're clueless about this issue, all they can offer is a replacement, which is nice, but to be honest, it's probably going to happen again even with the new device. My coworker has the same issue with his 16gb N5 black model. If anyone with this device trying out android 5.0 lollipop preview can chime in on if this problem still persists, would be very awesome. I'm going to wait and see when the official android 5.0 comes out, if that fixes the dropped calls problem, then N5 can be used, if not then I'm getting it replaced and reselling it, may go with the moto x+1. So either a good portion of nexus 5 devices are factory defects or this really is a cellular radio problem. Really hope that lollipop will fix this issue.
The APN only handles packet data and not voice so that shouldn't be the issue.
I would try setting your phone to 3G only for a while and see if the drops still occur when you are on 3G prior to the call.

Yea it wasn't an exact count but like 3 out of 5 says, enough that is annoys me. Tried all those as well and like I said I have a moto g lte that the sim worked in so it isn't the sim. This is my refurb unit, but the other one I have since November started to do the same thing in August as well on 4.4.4 never had an issue before that. Where did you find that if you don't mind me asking? I am comfy enough to mess with that stuff, so i'll give it a shot.

Already did and it doesn't but is an annoyance then since part of the price of the Nexus 5 is to have LTE and I am not getting the full product then which is not ideal.

I found it here (just take away the spaces after .com and after 02/): ianmarmour.com /2014/02/02/ google-nexus-5-fixing-modemcellular-issues-on-34g-networks
It's an older post from February, but seems to have the best details and fixes. If you simply search nexus 5 cellular radio issues or nexus 5 4.4.4 call drops, you should find a lot of these recalls from lots of N5 users. I'm tempted to try it, but don't really feel like sorting all my files in case i brick my device. I'm also not sure if ota update will work if i tinker with cell radios. Otherwise that's the page containing all the details you'd need including links and step by step guides. And hey if it works for you, let me know, maybe I'll try it out if it goes well for you.

Exactly, i know that's totally possible, but i wouldn't want a smartphone that has no lte and/or hspa+ service at this point in time. This seems to happen wherever lte isn't as strong or available but hspa+ is. I think the modem responsible for switching between lte and hspa+ causes calls to drop. I took note of it a couple hours ago when i attempted to make a few phone calls resulting in instant call drops. Seems to do it while switching from lte to hspa+ network. I just wish Google would stop burying their heads from the outside world like an ostrich, and get in top of this. I mean this is their flagship device until N6 goes on sale. They should seriously fix this issue or at least stop denying that they've never heard of any complaints with their N4 and N5 customers. I love this device, but a simple fix like this not being addressed by Google is not very professional, especially because it's primary function is to call people. I'm really tempted to flash those radios, but really want to see if Google addresses this issue with an official ota lollipop update.

Factor resetting it won't help, I've tried it already.

part of the price? no. you dont see any phone more expensive because it can handle lte. your issue is with your network, and its signals around you. as we all know that the lte available can not handle voice calls. your isdue involvez lte handing off to H or 3G. thats where your network comes in.

Then why does my moto g work fine in the same locations? And LTE isn't more expensive on a phone? Please explain then how a LTE phone is more expensive then the 3g variant. Go compare the moto g to moto g LTE. Defeats your argument.

lol, ok. the moto g variants are an exception to the majority. their already cheap price point being the reason.
those are two different devices, with differing hardware. its possible that moto can catch the signal from a little further away than the n5 can. the n5 was made less expensive because they used less expensive hardware in places. a shorter antenna being one of those places.

anyways, if you bought it from google, you can request an exchange.
I wouldn't try any hardware mod, etc as the issue is with the software. This kind of thing happens to me also, regardless of where I am or what network I'm on (tested this with a friends AT&T sim also). In the settings menu my signal strength just says "0" (kid you not ZERO) and sticks there until I manually set the phone to 3g when I go to a place with weak LTE (like a basement).
DISCLAIMER: I am only assuming this as I don't know that much about this topic, but I think stock 4.4.4 doesn't understand that LTE can still be received at worse than -115dbm and causes this fault. It doesn't matter which radio you flash (using the newest dev preview radio on 4.4.4 still has this issue, but on 5.0 it works flawlessly), what network you are on, where you are with strong LTE coverage... If you go to the wrong LTE dead spot you have this issue. It's as if the radio is saying "I'm still good on LTE" and the phone says "-115dbm isn't good we need to switch" and the radio says "I'm still connected to LTE though" and the conflict causes the signal to go to 0. I don't think it's got anything to do with the handoff from LTE to 3G either (but it might, as I said I'm no expert). -115dbm seems to be the doom number for me on LTE with 4.4.4.
Try flashing the new dev preview if you want LTE. No network = 0 bug. Hell I can even get LTE in my basement (at worse than -115dbm, of course). I had to flash back to 4.4.4 though, too many games/apps not updated yet.
Long story short, this is fixed in Lollipop. Less than two weeks...

It worked until august so your argument is void.

if it worked until august, then it supports my point of probably being an issue with your network, and not the phone itself.

But then why does my moto g work? Why is the issue also all the way from Philadelphia to new jersey to new York. That supports software if you ask me. Also it working it lollipop supports software. Also if it was network I think we would hear more about this issue from other phones as well
