Nexus 5 - Dropping network

My S3 died last week so I purchased a Nexus 5 and I've had nothing but issues with it since.
In 6 days it has dropped network about 10 times and just displays 'Emergency calls only' until I reboot it. It seems to be completely random.
Twice it has done it whilst streaming over 4g from YouTube, but it has also just done it whilst dormant overnight. I woke up the other day to find 'Emergency Calls Only' despite it being fine when I went to sleep.
After searching google I can now see that this seems to be a common issue with Nexus 5.
I'm seriously considering taking it back and getting something else, although I'd love to keep it if it works properly. Does anyone know the cause of the issue or have any workarounds? As I use the phone for out of hours calls for work, I can't afford to have it drop network whilst in my pocket and me not know about it...

Update radio or android, try different radios or reinsert sim. The network drop issue has been fix in 4.4.3

Do I have to root to try different radios? Android was updated when I got the phone and it's now on 4.4.4

You have to unlock the bootloader to try different radio's. There is a thread about it in the general section. Try to reinsert the sim first. It fixed it for me when I had the issue

OK so I tried re-inserting the sim but still dropping network. The weird thing is that it has done 3 times in the exact same location on my way to work whilst I've been streaming. It's as if it loses 4g signal in that location but then fails to switch to 3g and instead I get left with no network connection / no bars (empty triangle). It then fails to pick up the network again until I reboot (tried re-registering on network and airplane mode on/off).

Hmmm that sounds like an apn or carrier issue. Maybe they can help you

OK so re-inserted sim and spoke to O2 who said settings are ok. However, it did it again this morning in the same location. That's 12 times in 8 days I've had the phone, 4 of those in the same location (give or take 100m).
I think I'll take the phone back before unlocking bootloader and trying a new radio, but any other suggestions before I do that ? Factory reset ?

You have drops in the same location? Is that only with the N5 or with other phones too?

I never had it with my S3 in 2 years, using the same route into work every day. I can't remember my S3 ever dropping network once....or if it did it picked up the network again automatically. Only difference was I wasn't on LTE with that.
It's not just that location though, it's happened 8 other times in other place nowhere near. I only made note of the same location because it's where I get off the tram coming into work. This morning I wasn't streaming or anything, it was just in my pocket, but I'd installed light flow to audibly alert me when it lost connection.

Maybe set it to 3g instead of LTE, or else RMA/send the device

Yeah I've seen suggestions about changing to 3g, but that defeats the object of me having an LTE phone and paying for 4g service. Thanks, I think I'll take the phone back. My mate has an N5 and although he said he'd experienced it in the past, he hasn't since being on 4.4.3 / 4.4.4

OK so I've been and swapped my N5 for a new one...they also gave me a new sim. Fingers crossed !!

I guess I am too late to add anything but anyway here is what I did and may be of help. After pulling out the sim, use a pencil eraser and rub it across the contacts on the sim card. If the contacts somehow get too much oil residue from finger tips or other "impurities" on the contact, you will get incomplete contacting sometimes and it works other times. The eraser will clean those contacts up for a better dirt free connection. When I was a electronics tech in the hi tech field, I fixed many issues that were just contact problems and the eraser did the trick. I have had this same problem on my other phones (blackberries and androids) and it seemed to work.

Thanks. Either the new phone or the new sim seem to have fixed the issue. I've not had a network disconnect since (been 5 days now).

NEXUS 5 cannot connect to network?!

Hello,
So my phone just lost cellular connection. No bars no nothing. When i put my sim to other phone everything works . So i want to know is there any way to test if my nexus 5 hardware is failing or is there any other bug/fix what can i do to get this work. My phone detects sim card, it detects services but says cannot connect to this network right now, try again later.
PLEASE HELP!

I am having the exact same issue. started today around noon. i performed a phone reset and the problem persists. i would love if someone could help us out!

Hey guys I'm having the same issue. I was on lollipop, flashed Kitkat factory image, same problem. Have deleted, wiped, etc everything I can do. Tried safe mode. Nothing works. Started around 10AM today. It was working fine before.

I'm having the same issue. Has anyone found a fix?

has anyone found a remedy for this?

Exact same problem!!
Any answers wud be much appreciated

There is a known problem with a zero-battery drain killing the radio - i suffered it myself. Does that match any of your experiences?

I too am experiencing this problem. My phone died the other day and when I turned it back on there was no cellular signal. I can use wifi & bluetooth fine.
edit. I was considering replacing the antenna wires, don't know if that'll even help though. How do I troubleshoot this?

All of you check this thread:
http://forum.xda-developers.com/google-nexus-5/help/nexus-5-radio-refuses-to-t2834540
If your N5 runs totally out of battery, something happens to kill the radio module. I searched everywhere for a week for a solution - there isn't one.

[Q] No data

Hi folks!
Just got this xperia E3, had my old chip correctly cut to fit on the slot so calls and sms works fine. But I am not able to get data connection. I am in Brazil, using VIVO operator. Does anybody have any hint on what can I try to fix? Have already messed with all configs available, reset to factory defaults and started over, but no luck.
Could this be a baseband issue? Or what?
Tks, best regards.

Did you try to contact you mobile network provider and rule out the possible problem on its side?
Because one of the usual cases is the wrong profile for internet connection in the phone. So, maybe the settings weren't adjusted automatically and you have to call you mobile carrier and check you own settings asking to what help desk is telling you.

Not yet, just got it on for some hours... Since it is a time consuming task (some hours on the phone with provider support), will try to find by myself for now.

I dig on the internet and checked its settings, they seem fine. After a while I tried a totally illogic workaround: moved SIM card from slot1 to slot2, and voilá. It seems to sort of work, got edge connection at least. Went back to slot1 and again, no connection.
Seems a common issue on dual-chip mobiles, a fried told me. Have you seen that?

I have two dual-sim mobiles both working on the same principles - 1 module, 2 sim cards. They are both based on Mediatek CPU. Everything works fine either with just one SIM or two. Internet I mean.

4.4.4: Ok
Hi,
Just as a follow up, I flashed latest Sony 4.4.4 for D2212 (got it here) and it now works as it should.

[Q] Mate7 4g data problem

Hi all,
I've had this great phone MT7-L09 (softare version L09V100R001C00B127) since last December. My problem is that every now and then the 4g cuts off for a period of ten seconds.
It does not matter how strong the signal is nor which or whatever app I'm using. It just loses network. First thing I did was to change the old sim card to a new one. Did not help.
I was in contact with the Huawei support and conclusion was to send phone to service. OK. It came back with the same problem altough they changed the circuit board...so obviously they though that this would solve the problem. I did not. After messing around with it, trying to find if someone else was suffering with the same problem, with no luck, I send it back to service. Now they said that there is nothing wrong with it, but the problem is still there.
I havent noticed anything cut offs using 3g. It's not a major thing but it would be nice to know if its a firmware or any other software related problem.
If I use Netflix or similar where the data keeps coming it works just fine or if I use the phone as Wi-Fi hotspot, no problems.
It just loses network connection using apps like play store, facebook, whatsapp, twitter, every browser ie. firefox, build in browser, chrome, to name a few.
Should I just keep using it as it is or keep sending it back to service until they fix this issue???
Thanks

Sorry...one stupid question: have you already tried keeping the phone completely stock (without any application and/or software or any kin dof personalisation) for a couple of week and see if the problem still exists?
It really seems to me a software problem. Very strange.

I had the same problem with my MT7-TL10 golden version. For a week or so, the network used to come and go. Then ultimately the sim was not recognized at all. I sent it to Huawei service center and they told me that the sim slot is broken and I had to pay for replacement of the board which I refused. I was sure that I didn't break it. Now I am using my phone with one sim only.

Thanks for your reply,
I haven't used it only with stock apps for a week maybe a day, but first thing when it came back from service for the first time, I did not install any apps and it still lost the connection anyway...

I'm not sure, but isn't the sim card slot located on the circuit board??? If it is, it cannot be the problem, but I must try the second slot anyhow.

Man why everybody blames PHONE first??? like not trusting !
To fix this problem is to go to networks and u have to restore your apn to default it like refreshes then you can either just turn off data and then on and restart phone

Does not work, same problem after a numerous resettings. If I may add, I've have couple of other phones of which this problem does not occur.
In same place and conditions these phones work just fine not losing the data connection. Sure, if 4g is not available they use 3g, but never ever will the connection break off.

faulty 4G module tuner.. phone ... replacement needed...

change preferred network
Go to settings and -->mobile networks-->>preferred network and select "WCDMA only"..
It will fix your problem..

There is no such option in my phone settings, only the option to choose automatic 4g3g2g or automatic 3g2g or 2g, 3g only and 2g only. As previously stated no data loss nor connectivity issues using 3g. It's bit annoying sometimes when phone loses data connection altogether although signal is very strong. Just waiting lollipop upgrade if it'd solve the problem, I doubt it but...

network operator..
I think it's network problem..please contact your network operator..4g network have connection problem from some local area signal towers..so you just put other network company SIM card in your local area..(use 4g supported SIM only)

Thanks for your advice, but I don't think that it's SIM card problem because there is no problem what so ever using my other phone SGS5.

sorry

Hmmm. Sorry friend..I am helpless.. anyway continue your thread here..in Xda have brilliant members..they can help you..best of luck.

Thanks, I totally missed your comment...this is turning out to be quite a puzzle. I've noticed the less battery (<60%) I've have on the phone there seems to be nothing wrong with the 4g connection. ???

To answer to myself, I was too optimistic...nothing to do with battery. It's just so weird that phone works like a charm most of time and then suddenly not. I'm confused...

Now on the newest firmware lollipop 5.1 it fixed my lte problem

same issue
I bought mate 7 a couple of days ago and I keep losing the data connection. the network gets connected and lost again.
i did everything to fix it but no luck. changed sim, restored device, modified APN and no luck.
it keeps disconnecting seems that it is a problem with the phone itself as i have read the same issue on a couple of forums..
hope it is a software issue and get fixed soon as this is annoying.

In service they replaced my phone to a new one mostly because of this problem and I can say it did not help at all. Only upgrading to lollipop will fix the problem ( tested on beta) I'm on b145 now and it does that all the time. I guess it is carrier based problem not SIM nor hardware.

One Plus One unable to connect to wind network

Hey I have had my one plus one for a little under a year and after a 2 week road trip it has stopped being able to connect and detect the Wind home network. During this road trip I was on airplane mode for the full duration of the 2 weeks with the 05Q caulkin rom installed. Once I had reached my home town of ontario I had noticed that I could only connect to wind away on my opo. When scanning manually for the WIND home network it would appear with the simcard symbol beside it but when trying to connect it would state that it was unable to connect to the network. Although randomly throughout the day it would connect without warning until I rebooted my device where it would lose connection again. I then later updated my phone to the latest OTA which is cm12.1 hoping that the problem would be fixed but to no avail. At first it was the same issue where it would show the WIND network with the sim card symbol beside it but now I am not even able to see the WIND home network and can only able to see the Wind away network. I have tried changing my APNs and have tested my sim card on my sisters opo where it works perfectly fine. I have also done a factory reset and nothing has been able to fix the issue. I would like to fix this issue and anything would be of help.

Have found found a solution yet? I have the same problem. Sim card works perfect on OnePlus X, Nexus 4, but not on OnePlus One. I get connected to Wind Away, and I've tried just about every fix including entering in everything manually.

did anyone figure out a solution? im having this problem right now

Wow... sounds like I wrote this thread - aside from minor details this is EXACTLY the problem I am having. My vacation was also two weeks and the randomly connect during daytime but loses connection once restarts sound all too familiar. After Wind store clerk did sim swap, new error msg appears and said "your sim card does not allow connection to this network", so the problem actually got worse. Eventually I had to switch carrier (to Koodo and it works).
No, I have not fixed it yet.
But I'm contemplating to try manual selection of radio band (in the *#*#4636#*#* menu), because mine is showing EURO BAND and USA BANDas choices. Tho haven't made up my mind yet because that might do much more damage than good, based on some Google research so far... frustrating.
