Are you rooted?
P.S. Your wife works in a low reception area?

Looks like this is becoming an issue, there's two existing threads on it so far:
http://forum.xda-developers.com/showthread.php?t=1269282
http://forum.xda-developers.com/showthread.php?t=1269890
I'm hoping there's a fix soon because I love the phone and don't want to return it.
Edit: Just happened to me again sitting here at my desk with good signal.

Nope not rooted.

well what did you expect with the signal the phone has the same radio as the nexus. Crappy

I know the Nexus had a crappy radio but I never lost connection with it, especially at my home where I lost data/cellular connection twice so far

Unfortunately I cannot say that I have experienced this, while I am at work I have my Wi-Fi on 100%, and whenever I step outside of the office to use the bathroom, or to go to the vending machine (Wi-Fi signal still barely reaches), There have been several times that it would drop the connection because the signal was too weak. However as soon as I got back within proper range It would reconnect immediately with no problems.

well I called sprint last night and the reprovisioned everything. They said this is the first that they have heard of it and are sending the info to sprint and samsung. I will report back later if this fixes her problem. I doubt it will though, because other post have shown that this is just like doing a profile and prl update.

I just tested my WiFi again at work. I am standing next to the WiFi Router, and cannot get a connection unless I reset the phone. I am frustrated. I cannot reset my phone everyday when I come to work just to get a signal.
I just jumped ship from AT&T's iPhone to this, and need to decide where to go next. Verizon Bionic?

I had same problem happen last night. Showed the international no symbol and didn't get a signal until I rebooted.

Airave works great

Out of curiosity, who here has an airave? My mother got hers yesterday for free for being a loyal customer for 11 years and also because of her horrible coverage in her home. I actually called customer service to see if she was eligible and she was. She used to get 1 to 2 signal bars on her epic 4g touch and now she gets full bars. Her 3g speeds went up 1.5 mbps from .3mbps. She's pretty happy with her airave . I also find out that they are planning to build a sprint tower about 20 minutes away off the highway from where she lives. No reason to leave sprint anyone time soon . Hell if the Tmobile and AT&T merger happens and I hope it doesn't, I'm heading to Sprint.

I don't know about Sprints version but we've used an At&t microcell for over a year with little to no issues. Had to pay $150 for the damn thing but it's been great. They should work similarly.

Have had ours for some time now. Had a couple issues with it, but was always resolved within a timely manner. Without out ours here in the home, we'd see 1 bar if that. Got ours free from the problems that we've had signal wise.

Got an airave v2 from sprint for free since my basement drops calls, works great throughout the entire house, sometimes it doesn't switch properly to the sprint tower when I get out of range outside and drops though, but that's a rarity

I have a new version Airave in my home (got it for free from Sprint cuz of poor signal quality indoors), and it works very well.

That's great that some have it especially for free. One question, does anyone have the GPS blinking green. When I first set it up it stopped blinking green and noticed now that it's blinking. I don't have the airave near a window nor elevated because of how her computer is set up and located. Should I bother connecting the external GPS or just not worry about it. My mother won't use her GPS whatsoever. Thanks.

Gps has to get a signal before airave will recieve data. As well as in highest level of support every call was airave. They work for a while and stop. We had an airave dept, but the calls were in the 100's every hr. We had to take all the overflow airave calls. Hate those things!

I used mine without the extra gps ant. For a few months with mixed results. After a while I noticed the gps light flashed often, so I hooked up the external Gps reciever. Night and day diffrence. The airave never skips a beat, and signal is 100 fold better.

I can't get my airave to work. I have it after the router and the GPS and Mobile lights are still blinking.

if your having issues put it before the router

Airave here. I like it and it works. Was free via sprint rep

I want it after the router. I dont want to use the Airave's routing capabilities since I already have it set up on my linksys router.
I've read that you that you can just plug it in and it should work. I have tried changing the IP, etc. So far nothing.

It needs to be close to a window or attach the GPS antenna to a window. Also first time plug in could take hours to go solid lights.

I want to have it after the router as well, and thats where mine is; however, in a situation like yours where your trying to fix a problem its time to troubleshoot. If you put it before the router and it works then you've identified where the problem lies...

I have 2 of them Since i have a large family on my account that live in 2 different cities they gave me a second one free.I love them while in house i get great download speed and calls are not a issue.
I got it more for the download speed then anything else plus helps with tether

Wait... Your tethering from your phone which gets its signal from the airave which gets its signal from your home Internet connection?
I see two middle men that can be cut out of this equation

I too have crappy signal at home. For those who have gotten unit from Sprint free do you still have to pay the monthly airwave fee? Seems to be unfair since you are using your own internet service provider to hook the airwave to.

By the way to all of you who want it after a Router, I have mine setup after a Router. The steps are easy just gotta port-forward. Google it =)

I did google. I also have the ports forwarded. The mobile and GPS leds are still blinking. It might come down to my charter service is not that great for VOIP (I even have OOMA too). I suspect it's that.
Shoulon, what steps did you do for after router setup?
Thank you.

CDMA GNex Signal Issues

I just got my VZW Galaxy Nexus this last week and I've been experiencing signal issues. Often when check my phone, it will have no signal at all which can take some time to come on, and then its sometimes even longer before I get a data connection of any kind. I am in Lincoln, NE so I have 4G here which works great when it works. Is this a common problem with these phones? I rooted and installed CM9 that day I got it so I want to determine if I have bad hardware that needs to be exchanged or bad software that can be fixed. I found the 4.03 leaked radio on the boards here and flashed it, which has seemed to help some but I still have issues. What is everyone's experience with VZW and the GNex?

Common problem seems to be the complaint of a longer "connect to network" time, both on startup of the phone and if data is lost or switched down from 4G to 3G
The consensus seems to be that its a s/w issue that can be corrected.
Oddly enough, I was standing in the middle of our local shopping mall with no bars, yet did a Google search for "Verizon Wireless" (go figure, right?) and it came right up....no it wasnt cached. Just shows that our bar readings may be inaccurate, so who knows what else might be inaccurate. I also had my phone right next to a demo GNex at the Verizon store, and the demo was showing 2 or 3 bars of 3G, while mine had 1 bar of 4G......so which is better, 1 bar of 4G or 3 bars of 3G? Judging from app download speeds, Id rather have 1 bar of 4G anyday.

I have seen some comments about the bars in the status being in accurate, however when mine has no bars it seems to be that way. I am unable to use the internet, text or call which is an issue for me.
I also should note that I use JuiceDefender to control my data connection. While this should have no bearing on my phone/text connection, I am wondering if it may have some affect on the 4G connection even after I have the screen on for a bit.

I have 4g disabled and haven't had any issues. I'd try disabling it, restart and see if it happens again. Make sure its still disabled after restart.

I've been having big time issues with mine. Lots of time I go to pick up my phone and it has service, decent service, but won't connect to data. Once I'm connected it is not an issue but if I'm on wifi at home, and turn it off, it just doesn't want to connect unless I reboot.
Rooted and tried a new radio. A little better but still has been doing some weird things.

How long have you had yours? My biggest question that I'm trying to answer right now is if I have subpar hardware. Since the phone is only a week old I know I could return it to stock and easily get VZW to give me a new one. This may not be the case two months from now however.

I've had it since it's been released. The newer leaked radio is better, but it also does weird things too. I don't know if this is because I'm in a 4G town or what.
I don't get 4G where I live, but my buddies with a Bionic and Rezound do here at my house, albeit it's very sketchy for them.
Thing is, I'll have good 3G signal if I'm driving, but for some reason (at least with the original radio) it wouldn't connect. Still testing.
So far the newer radio has been better, but hasn't fixed my issue.

at my house it sucks a few blocks down or anywhere else its rock solid so i just wifi at home better for battery anyway

I hit dead zones where i really shouldnt be. Downgraded from 4.03 to 4.02 and the jury is still out. Might be overall software issue like OP said.

Sorry to hear you're having the same problem, but I am glad to hear this sounds like a correctable software issue and not isolated bad hardware. Hopefully VZW will make some improvements to their LTE network and get some radio updates for us soon. I'm in the same boat as you, the 4.03 leaked update was a definite improvement, but a far cry from being a total fix.
As for when my data connection is working...holy hell is LTE fast. I'm clocking it in at 12-16Mb/s, which is killing even my home cable connection. I was confused as to why something seemed slower when I was at home using wifi. I disabled my wifi altogether since I'm lucky enough to have an unlimited data plan still.

Big issue
I have replaced three verizon Galaxy nexus's....all of which, each day i switched...i was either on the phone with a tech dude or (2 of them) one on one at the verizon corporate store.
All of them confirmed that there is a reception issue.
I reside on long island...specifically in the nassau area...4 towers around me..its HEAVILY 4g and 3g...3g is lower than 1mb...i actually never reached 1mb.
ever rep said its 'odd' and 'seems wrong'
now i love this phone...the one i have now..no different then the others..and unfortunately im waiting for the one i mailed to reach them ..to switch yet again.
the problem is..idk if i can handle this issue (4g drops to 3g and has to manually move back which takes forever..and very very slow pick up on any of them)
i want to believe this can be solved by a radio update..but judging by the insane amount of tries i have (every type on every version 4.0.1, 4.0.2 and 4.0.3 with kk6..there is no improvement,
im praying its a software..im waiting..and i have a feeling come january 15th...when everyone who has the phone is officially locked in it and loses the worry free exchange..is when verizon or samsung will actually admit whatever problem this is.
what kills me is i left tmobile for this (7+years) all nexus's ,,all unreal connections with free tethering and $65 a month (tax included)...my wife took my plan...and i took hers (she is grandfathered into unlimited data)
Now she has a sgs2...clocking in at 12mbs at home..ON AVERAGE...with fasstt radio switching...mine is unbelievably unstable sometimes can hit that but averages at 6-8. and in this house my wife got amazing connections on her previous 4g phone. very odd stuff, hers to the 4th one being the lucky one!
go figure!

I really wish this phone was more reliable with its signal, and hopefully VZW will get it taken care of. I'm debating about calling in to talk to a tech, but I'm not sure if I even want to because I don't expect anything to be done, and I don't want to swap phones for another one with the same issue. At the same time, I think I'd rather have this phone with some issues over the Rezound or Razr (once you go ICS, you can never go back)

At&t S3 Dropping Data Connection

Has any of you had problems with your s3 dropping data connection? The phone completely loses data for about one minute and then comes back on its own.
I ruled out a geographical relation since it happened while I was in Miami and now that I'm back in Boston.
Thanks.

This was happening to me today, first time in about two weeks since I have had the phone. It was acting pretty crazy. Hope it doesnt stick around.

I guess not much people, mine is doing this now. Had my phone about a month. Except mine won't come back without restart and even that doesn't work sometimes.

I've noticed this happening as well on Telus with both the S3 and iPhone 5, even with a strong signal.

Yup mine is with full signal too. BUT when I go into a 4G LTE Area I get my data back.

Ya same issue here as well. I just noticed it today on my Rogers sg3. Just basically losing all data and then re-appearing suddenly. Sometimes it requires a reboot as well.
What Rom are you guys using? I'm running CM10 stable but it seems to be a known issue with this rom.
I tried creating a new APN taken from directly from Fido's site but for whatever reason it just keeps reverting back to the default APN.
Some help would be greatly appreciated with this very annoying problem!
Thanks

[Q] Signal issues UK

Hi. I am on three network UK and since I had the m8 from new, have had intermittent signal issues. One minute I will have 5 bars then it will drop to one bar while I am still in the same place. This is my second brand new m8 now with the same problem as the first. I also have a moto g on three to compare it to, and the reception on the moto g is far more stable. I can't find any posts from the UK of anyone with the same problem. Anyone else having signal strength problems? It affects signal as a whole as in both calls and data.

Im with 3 and have intermittent signal issues but thats nothing to do with the phone or network provider in my honest opinion.
Are you running a custom rom? Might be a radio issue?

Thanks for reply. I am still on stock at the moment because I didn't want to have to un-root and return to s-on etc. While I wasn't sure what the problem is. If you don't think it has anything to do with the phone or the network provider, what do you think it is? As I say, my moto g signal is far better and stronger. I don't get signal on the m8 where I normally have done on all my previous android phones. Thanks for any more input.

I'm on 3 and also have ****ty signal strength, yet I'm able to make and receive calls without issues.
Tbh I think it's an issue with three.
I was with Vodafone back in the day, and use to have full bars yet intermittently I was unable to make/receive calls.
3 appear to have some Gremlins, but after using almost every other provider, oddly they're consistent.

Thanks for reply. Tbh, I have been trying to not take too much notice of what the signal strength bars are telling me and just trying to use it anyway. But it just seems strange to me that I have only just started seeing this happening since I got the m8. As you say, three have been consistent, and for me, they have been consistently good. I now find the m8 not having data connection and no bars where before, other handsets are fine. Oh well. Thanks for your reply.

Hi. I have sent mine in for "repair" now, but am not holding out much hope that it will be working any better when it gets returned from HTC. I am in Hereford, west midlands.

Got the same, now on a second device thanks to the local thieves;anyway both handset's had the signal bar observation you made in the post.
So I'm guessing it's 3's network.
I'm in South east London.
Data & voice are a bit hit & miss

Thanks for reply. I think what i'll do when I get my device back, is to try a few other networks sim cards and see what happens. Perhaps I should have tried that a bit sooner but as I never had trouble before, it didn't really occur to me that it could be the network not playing nice with the phone. Thanks for all the replies guys.

I've been noticing signal problems too with three. I'm in Northern Ireland. I tweeted them and they said they were aware of a mast issue near where I live.

I had been with 3 UK for about 5 years and a couple of years ago I had a Desire HD and I was experiencing the same exact issues except sometimes the signal would get lost completely and even airplane mode or phone reboot would not register with the network again but since then they have improved the network (a little), I can tell you there is nothing wrong with your phone or the radio. 3 have great deals but their coverage is very patchy I am now with o2 UK and have not had any problems with reception or dropouts. one more thing; a bad simcard can cause reception issues so you might want to try another sim from 3 to see if that helps at all.

I have exactly the same issue however it doesn't seem to effect the usabilty of the phone. I had a Note 3 before which also suffered the same issue so I would assume it is Three.
I think Three are in the midst of a big 4G switch on and from what one of my pals in the store said they are doing a hell of a lot of work on the masts at the moment. I do however have a more consistent signal with the M8 with regards to signal stability (not the bars)
You may want to look at getting an app which measures the actual -db rather than bars. It may be that you are swapping between a couple of masts.
Have a look at Opensignal or this one https://play.google.com/store/apps/details?id=com.signalmonitoring.gsmsignalmonitoring

I have been trying not to take too much notice of the bars and just use it anyway but it still doesn't seem to be working as well in certain places, as my other handsets have previously on three. Oh well. I just took out another 2 year contract with three. I'll see how the network performs over this time and make a decision when the time comes.
