S4 signal drop 'emergency calls only' affecting my s4 - Galaxy S 4 Q&A, Help & Troubleshooting

Hi all, I am on 'ee' (UK) And am constantly having my signal drop and not recovering, doesn't seem to happen on my work phone (Xperia sp) just wondering if anyone else is having this same problem on the s4. There was mention of it on the UK s4 thread but for some reason that was closed (read the pinned topic still seems nonsensical) I am now downloading the latest btu update (luckilly linked in the above mentioned thread before it was closed!) Just wondering if you've had problems whether that fixed them ( started the download but torrent and extremely slow. Would love to hear your thoughts!!

I live in Spain. My operator is Yoigo and i have the same problem. They said that is because they're changing to 4g network. I think the real problem it's the phone

This is what I'm trying to ascertain.
My colleague had an i9305 (s3 LTE) and gets similar problems but my work phone (xperia sp - also a 4g compatible device) isn't affected. Thing is people can't get hold of me and is driving me crazy!!

Been happening on my I9500 since day one, phone completely loses signal (like goes into airplane mode) and comes back a few seconds later.

I am having the same issues on t-mobile in the uk, which is part of the EE group now. signal goes to crossed circle, emergency calls only, and i have to restart to regain signal, i am pretty sure its the handset as i also have a nokia 820 lumia with no issues .
To be honest its not a big issue happens once or twice a day, i just don't want to send the phone away have it flashed and be told thats fixed it...

I had that before the 4.2.2 update but all is fine now.

Had the same problem a few days ago for the first and only time. The signal was gone and came back a couple of times. After I restared the phone, everything was working again. Didn't happen ever since. I noticed that the phone ran hotter than usual.

Do you have a self-made microsim or factory made? A poorly cut microsim can cause such problems. I replaced mine with a factory made microsim and these kind of problems went away.

Hi, factory sim, I have reseated it etc.
I'm thinking its a network rather than phone issue though. Like it doesn't reauthenticate after lost signal. Signal is poor at work but its not the only place it happens. I never had the same problems with my s3 making me wonder whether it is the LTE radio that causes the problem, too much of a coincidence that my colleague has the same issue with his i9305 (also LTE radio)

signal droped on my S4 as well
Hello,
It happens to me twice: once per week - I'm brought it two weeks ago. First time I have simply reboot-ed to get the network back.
Second time I have put it in "Airplane mode" and back to normal operating status but doesn't recover it. I have only seen the operator logo about 1 sec and then "emergency calls only".
Reboot "solved" the issues instead. I have cleaned the SIM surface and reinserted few times and I have set up the network mode to "WCDMA/GSM (auto connect)". Under observation...
See this post as well:

Will be back here with feedback,

Help me please: Losing signal more than 20 times a day.

I'm from Brazil and having issues with Nexus S since I bought it.
Before, I was with KB1 radio and could not have GPS fixed and was losing signal several times a day.
So, I updated to KB3 and it fixed the GPS issue but the network signal issue remains or even got worse.
I'm losing the network signal more than 20 times a day and the only solution are reboot.
Could someone help me please?

it could possibly be the signal towers, most likely it is.
you can also try to flash back to a stock ROM + stock Radio and see if it fix itself up
Can I put the Galaxy S radio in Nexus S? Because we have Galaxy S here in Brazil.

very simply... no.
try the JK8 radio? or try flashing a custom ROM to see if its a firmware related problem
also verify your KB3/KB1 packages with MD5 hash to verify its 100%
I'm having that problem also in my nexus S and on my wifes Galaxy S
BOTH are stock roms. Really weird. It enters like 1 or 2 times a day in "Emergency call only mode". Weird thing is: signal bars are FULL but emergecy only text on my lockscreen.
My carrier: VIVO, são paulo, Brazil.

It's a radio issue for sure.
Nexus S is coming to Brazil next month. Let's see which radio it will use here.
Its really cool seeing us brazilians talking here... You know, I dont have these problems at all but sometimes the 3g bars greys and than reconnect again. This just irritates me when on youtube, when streaming is interrupted.

Hi,
You are at Oi, and we are at VIVO. MAybe it's a issue with VIVO carrier.
Here in Rio, using TIM.
Sometimes I get signal lost, but it comes back without needing a reboot.
At work, 3G signal is very unstable. Leaving my Nexus at the same place/position, I get two bars of 3G signal, then suddenly full EDGE signal, then it comes back to 3G.
At home, I get 3G all the time.
There's another thing I've noticed: sometimes when I receive or make a call, after I hang up I lose connection (3G or EDGE). It takes about 10 to 15 seconds to recover it.
I have a Nexus S i9020, 2.3.3 stock rom and radio.
We have to know if that happens in the US. If yes it is our carriers, if not it is our basebands.
Im going to leave oi because the 3g speeds are horrible the max i got was 1030kbps. At Vivo speeds can be 2 times (Or more) better!!!
Sent from my Nexus S using XDA Premium App
Bad news for me: I've tried today all radio baseband avaible in XDA and all of them I got signal lost during the day. The worst KB3, K8, K1. In this order.
I don't know what more can I try.
If It won't be fixed soon, I'm sure my next phone will be a iphone 5. I love Android but can't deal with their bugs.
This is issue of the VIVO in some estates like Sao Paulo in a lot of phone models. They just knows about it, and they are correcting this issue.

But why only by rebooting the phone whe can get again the signal. Signal drop is a carrier/network issue but cannot reconnet to network it's a phone issue.

Remembering my ancient knowledge about cellular networks, a cellphone sends a registering signal to the radio-base station from time to time. If the RBS doesn't acknowledge this, this cellphone will lose signal. When you turn off the phone and turn it on, you are forcing a registering. Maybe then the RBS registers the phone, and then you get signal.
What I'm trying to say is that maybe it's not a cellphone issue, maybe it's an operator issue.
Have you tried using another phone with your SIM? Do that and check what happens.

Yes. Before the Nexus S I had a Motorola Milestone and It never happend.
When it lose the singal, the Nexus S can identify the RBS but cannot register. Even If I restart the radio with an app or swtiching to airplane mode and switching again to normal mode, It can't register. What the diference of restart the radio or reboot the phone? Is it not the same "force"?

All Nexus 4 devices faulty?

Hello,
I am from India and I'm using Idea Cellular.
I've been using N4 since Jan, initially it had 4.2 on it, after that I updated to 4.2.1 and later 4.2.2
For the last 6-7 weeks most of my calls were getting dropped, sometime just after connecting.
I tried a lot of solutions:
1. Switching off mobile data
2. Switching off wifi
3. Device reset
and then making calls.
None of the above solved the call drop issue. I finally requested for a replacement device and received it today.
So I put my sim in new phone, copy all my data from Google Play and I make my first call, 12 mins and the call drops again.
Now if this was a hardware issue, the odds of me again getting a faulty device should have been very less. But well here we are - one more faulty device.
If its not, is there any software fix or anything other way of solving this?
Did you try checking with a different SIM?
Hardware issue with your particular phone. RMA
Maybe is your sim cause I can talk for over a hour and nothing happens

Got it on my HopShopGo US address and shipped it to India. Had to pay Rs 2776 for Customs/Octroi and some $28 for shipping.
Google has blocked $350 on my card and will reimburse it once I send them my old device back.
So disappointed with Nexus 4.

I've had mine for about a month and have not experienced any of these issues. Yes, I've had a dropped call or two but it's been in areas that have a weak signal and my previous phones would also drop calls. I'm on the T-Mobile USA network.
It might as well be a problem with your service provider, and it might be temporary, you should check that possibility. If not, then the SIM card might be faulty as well, try it in a different phone and see if calls are dropped.
Tried switching already.. No avail..
Main things that bug me is wifi.. Don't know what the heck is wrong with it..

Using N4 since 3 months in Mumbai with Vodafone never had problem like that. May its your device or SIM or network is getting worse at this time in your area.
High Hopes
I feel ya, man. My phone usage pattern is pics, video, and browsing mostly. The Nexus 4 has failed me on multiple occasions with dropped data and terrible reception. I have tried changing my APN settings, I've even called ATT and confirmed with them that I had the correct data plan allotted.
I know it's the Nexus 4 and not my carrier because my husband, who uses a half-broken iphone 4 on the same network gets better reception and network connectivity in the same places and at the same times. I found myself using his phone a lot of the time to do simple tasks like browse online because I'm tired of re-connecting on my Android.
I still don't want to go back to iPhone because I'm bored with iOS at the moment, so now, when I'm researching my next Android phone, I'm going to make sure to consider radio signal quality.

I have seen issues with SIM working on one phone but acting weird on another. Try checking with 2-3 different SIM cards of various service providers. If all fail, you will know the device is faulty.
FYI, I am on Airtel MH Nexus 4 and haven't faced any issue.
I have the same issue, the call drops when making or receiving a call, and it happens after 20 seconds to 1 minute... The odd thing is I didn't have these problems when I was using it in the states.. Just had them when I went back home..

No issues for me too. From Mumbai, on Vodafone network. In fact the reception is better on Nexus 4 than my previous phone which was a Motorola Electrify.
i'm from Mumbai, using Tata Docomo, and have no problems with my nexus 4!
Try your sim in another phone now.. Might well be your carrier

I have recently swapped SIM on Nexus 4, from BSNL to AirTel. When I was using BSNL, 3G was working fine. Once I switched the BSNL SIM with AirTel SIM. I got 3G the first day (14th March 2013) and after that I was never able to get 3G till now. I even got a duplicate SIM thinking that earlier SIM might be the problem as I had converted it to micro by cutting it. But new micro SIM doesn't seem to be helping either.
Any help would be greatly appreciated.
my prob
i am in india . i got my N4 from the USA in mid feb . i started using it after i reached india . my phone makes a creaky sound at the top left part when pressed slightly . and also there is this weird sound from inside the phone when i shake it . sounds like some really tiny part is loose inside it .i have never dropped my phone and there is no damage externally . i am considering getting a replacement . so how should i go about it ?
please help fast because a friend will be going there soon so ill send it with him .
thank-you

Signal strength on my new Note 3..

Does anyone have a problem with their signal strength....mine will show 4g in an LTE area....it will switch back and forth from LTE to 4g constantly...sometimes the signal strength would be so low, that web pages wont even open for a min or two....I am using a sim adapter to use my sim card from my iphone 5, instead of using the new sim....I switch back and forth between my iphone and note, so I don't want to use another sim...does that cause problems?
Are you in Australia?

Mine is rubbish
Well the actual signal strength is fine when its working, but it has real trouble re-connecting to my network (3, UK) after going out of range.
It sits on the 'emergency calls only' mode for ages, and requires a reboot, after which it immediately connects to my correct network.
Its made slightly better by manually selecting '3' as the network operator, but I have to reboot several times a day to keep connected.
Im planning on going to Car Phone Warehouse tomorrow for a chat about it...

ripnetuk: Just as a suggestion:
My NexusS tends to not to reestablish the data connection after a weak signal period. I can fix that by switching to airplane mode and back. (Rebooting takes ages with that phone).
Hi,
Id established that sometimes putting airplane mode on and off fixes it, but it often didnt. A reboot /always/ reconnected to the three network.
I took it back today, and Carphonewarehouse swapped it for a new unit, no questions asked, so im gonna give it a go for a while before thinking its fixed.
I did get my highest ever speed test result with the new phone tho - over 15 megs... ive never seen over 12 before, so hopefully its got a good antenna on it
g
Swapped for another unit and it's all working properly now so it was a lemon device causing it..
Phew!

I compared reception and signal between my Note 3 and HTC ONE in Hong Kong. I found that the HTC ONE and the older LTE Model of the Note 2 got better reception/signal when compared to my new Samsung Note 3
How long did you have your phone before you changed it for a new one?

Weak signal, poor reception, dropped calls

Anyone else having these issues? I've noticed that places I always had at least 1-2 bars with my note 2 I will not have any service with my note 3. Also I have been dropping calls in areas that I never did. Could this be my new sim card or should I exchange my phone? I also feel that my wifi connection stability/range is slightly worse than before.
Mine is the same way,don't get the signal my note 2 would and 4G is weaker also .

I hope this is just a first software or sim issue. Or at the very worst a first production run issue. I will likely be bringing mine to Verizon this weekend to test and new sim or exchange if that doesn't make any difference. Annoying.
Idk how much it will help you but I noticed I was in 3G a lot of the time as well. Definitely more than my N2, I switched my preferred network to LTE/CDMA instead of Global and I now have 4GLTE way more. As far as the wifi and phone reception, I myself haven't noticed any huge difference but I did read the international version of the N3 already received 2 updates and they supposedly not only improved the wifi and antenna signals but also battery life. Who knows when we'll see an update though. We are on Verizon.

Tried that and it actually made my signal significantly worse. I switched back to global and my problem seems way worse tonight than any day this week. Can barely hold onto a signal in places that I never had an issue before. Battery pull didn't help at all. I constantly get a message that says I can't send messages and then asks me to retry. Frustrating, will be going to Verizon tomorrow or Friday to return/exchange
Just now noticing this
I wonder if this has anything to do with being rooted? it seems like I just started dropping calls like crazy just today. I do remember getting the sent error on some text messages, though I can't remember if that started befor or after rooting.
Haven't had a single issue with signal or dropping calls. Also my 4G speeds are pretty insane. I'm thinking there are some units with defective radios.

my note n9005 dropping carrier signal.!

i have n9005 build mj7 and root
today received 2 text message (carrier service) that these people tried to call u, when i called those 2 friends told me my phone was off, which never did
after e hours when i was installing some stuff and found an icon that no signal while in battery consumption screen : cell standby i got : time without signal 0%
i went to connection and choosed my network to get signal back
then after 2 hours i tried to call my phone several times and it was giving me an answer that my phone is off althoug carrier signal pars were full!!, and had to restart phone to get it work back
what is happening?
which is a good app by experince can alert me when i lose signal?
tried reset signal app but it crach each time i try it, may be not compatible with 4.3
found no signal alert but never updated since August 2012, trying it now
is there any way to get a log when i lost the signal
I got similar issue. My note 3 network strength is worse than my old note 2 was.

I have a slightly different issue. My data stops working even though it shows 4G signal connected. The up arrow is blinking but the down arrow is not. It happens randomly and will also start working after some time and then stop working again. None of the services work when its not working like opening any site with the browser fails. I am annoyed with this. The same SIM when used on my Nokia 920 doesn't do this. It's constantly working for days. Something with my Note 3. Not rooted. N9005 LTE. UAE. Is there any way to diagnose this? If I restart the phone it starts working again immediately. I don't want to do a factory reset.
there r some apps on market which will alert u if lost data connection and allow u to reset the service by 1 touch

My Three sim card was awful for signal on my note no matter what area I was in, but turned out it was a bad card.. My O2 sim has full signal and full 4G connection though all the time anywhere.
My Vodafone 4g had been pretty sheeeit since I've had it. They can't explain why. So last few days I'm on stock and just rooted... Not that many mods and it seems to be holding much better signal and showing LTE as well. Getting 91db whereas it was 101db before.... I dunno what's going on

They went out of action totally last week for a few hours and have yet to fully recover

From previous experiences... Signal was always the best but it's been 3 years since I had them..... And boy have they gone shhhhit. I got o2 contract as well but not 4g as they hadn't rolled any out and weren't even promising to do so. My local Vodafone store told me how they have bought the best equipment and all that shhhhhhit and I thought it to be true..... Man was I wrong. I suppose free phone for nothing as it stands....
