[Q] Drop Signal

I'm rooted using Axiom 2.2 and every once in awhile my phone will go from 4g to no signal at all and i didnt move or anything or change networks. It just completely drops and then will come back after 20 seconds if i switch in and out of airplane mode or restart my phone. should i flash the leaked 4.0.3 radios. will that help at all? or any other suggestions?

If you're in the US and on Verizon it's a known issue, something to do with how they've set up LTE which I didn't bother bookmarking. There's several threads on it scattered about.
If not please supply more details of your setup.

yea im in the US on verizon but my friend has the nexus too and his doesnt do that were both hacked with the same exact set up. i know 4g is an issue but im in NYC and i should never be out of 4g and if i am i shouldn't lose 3g and data completely and no txts or calls while its out

Is this what it does?

My first Nexus did this. Tech support had me go to a store and have them swap out the SIM card...but within the first 5-10 minutes after I left the store, it did it again twice. I went back to the store, they swapped out the phone, and the new Nexus hasn't done it one time since (this was about a week ago).
If, on the other hand, your phone maintains at least a couple of bars of signal but just loses the 3G/4G icon for a while every so often, it could just be Verizon's 4G network acting up. This can cause intermittent data drops, even if you're in a 3G-only area. Give it a day or so, and it should clear up.

thanks kinda what it does where it just goes out and comes back but my speed has never been that slow i always have good download and upload speeds just lose connection every once in awhile. would flashing the 4.0.3 radios help at all?

It's not a faulty phone.. it is just LTE growing pains. Yes you can probably get them to give you a new device, but it isn't necessary.
Also, the newest radios might help.. and if they don't you can always switch back

yea i have 4.0.2 and 4.0.3 on my phone so if 4.0.3 doesnt work i can just flash 4.0.2 and then ill be fine?

In terms of radios and roms, yes you can flash a 4.0.3 rom/radio or a 4.0.2 rom/radio. The trick is just to find which radio works best for you as not every device is the same

Seems like its more of on the Verizon side not really a phone radio issue.

Only problem im having is dropped calls but not short calls seems to only happen at about the 15 min mark on all long phone calls.
I keep a steady data connection at all times

[CDMA/LTE] Who DOESN'T have signal drop issues?

Ok, so I am on my 4th replacement Galaxy Nexus (CDMA/LTE) All of them are dropping 4G signal every 3 to 5 minutes, but sometimes will go as long as 30 minutes or an hour. Either way, there's WAY too many signal drops. And, for clarification, I don't mean low bars...I mean going from 3 or 4 bars to no connection with the "x".
My original one was I515.09. All of the replacements have been I515.10's. I know the .09 / .10 are the hardware versions (.09 make in Korea and .10 made in China I believe). My wife's does not have the problem (.09 version), my brother in law does not have the problem (.09 version) and the one in my local Verizon store does not have the problem (oddly, a .10 version).
Regardless of what Verizon and Samsung say, this is NOT a coverage issue; it is either a hardware issue or something in the software causing interference with the 4G radios (it doesn't affect 3G signals, only 4G).
The problem seems so prevalent that I decided to do a poll...who among you DO NOT suffer from the signal drop issue? And, if you don't mind, provide a little information if you don't care. I am doing this in hopes of figuring out if this affects all .10 versions (obviously it does not). And if you have a .10 and do not have the issue, I am trying to figure out what combination of roms, kernels, and radios are working for you. I know that none of the variables should affect the signal drop issue, but for some reason some kernels and radio combinations seem to do better than others..
Do you have the issue?
What is your baseband version (.09 / .10)
What rom are you using?
What kernel are you using?
What radios are you using?

Fellow GNex users,
I have been having this same exact problem, too. My original phone was a I515.09, purchased back in early May 2012. Unfortunately, that phone had separate issues with it and I had to send for a replacement. Here I am, two replacements later, and I am experiencing the same issues the OP has. However, with the second phone, I decided to try and isolate the problem, and in an effort to save people some time, I thought I would post what steps I have already taken to try and resolve this issue. The bottom line: I believe it is in fact a hardware-related issue with the newer phones released and/or some firmware issue that is impossible for a user to manipulate.
:::None of these solutions resolved the problem:::
Replaced both the battery and the sim card
Rooted the phone, replacing the bootloader with CWM and installing AOPK milestone-5 on 4.0.4 (full wipe)
Manually installed the latest 4.0.4 Radios (FC04/05)
Installed older Radios (EK04/06)
As for some .10 versions working, it seems there are a few .10's floating out there that have existed at the launch of the product. It must be an older version .10 that does not suffer the same hardware issues that all the new ones have. I have even heard, first-hand, of people purchasing brand new GNex's and experiencing this problem, too. Therefore, I think it extends beyond just a "replacement product" problem.
:::My Solution:::
After talking with a "level two" technician at Verizon who handles dispatching replacement phones, I have requested a notation on my account to send out a baseband version I515.09 (the technician had all .09's at his disposal at the facility, so he was certain there are some in stock, as well.)
I will update this thread after I receive my new replacement, most likely this Friday.
:::UPDATE:::
Just got off the phone with Verizon/Samsung and received some troubling news. According to Verizon, it is basically impossible to know what version they are sending you. As for Samsung, the representative said she is unaware of any problems of this magnitude with the Galaxy Nexus and does not see any updates to correct it in the foreseeable future.
Looks like we are up a creek on this one. It's a sad day, but getting a different phone as a replacement may be the only option we have.
:::FINAL UPDATE:::
Just got off the phone with Samsung. I wanted to call them directly to make sure this issue was reported. After some digging, the representative saw a ticket for a known issue with some versions of the Nexus where an error in the firmware keeps causing the modem to reset, thereby creating the constant dropped signals with 4g. There was no date scheduled for fixing this problem, but he mentioned the ticket saying it would ultimately be resolved by a firmware update over the network.
In the meantime, I did discover that the phone should function properly if you run it in CDMA mode only. I recommend moving to 3g for the time being until a patch can be pushed out to us.

I did but only at my house, where coverage blows. I got a free Airave, problem solved.
Never happens when I'm out and about or at work.

I was having this problem a lot when I first got the device and was running the stock 4.0.4 and I'm on the .10 baseband. I tried a couple of the cm10 ROMs and the problem seemed to persist, but then I tried paranoid android and haven't really had an issue since. I found it to be rather odd, but so far so good since this flash.. keeping my fingers crossed that I didn't jinx something.

I am on my second Verizon Galaxy Nexus. So far, 4G has been miserably bad here in Raleigh, NC - including right inside the Crossroads Mall Verizon company store where they swapped me a new one out for my current new one. They did that because I was going on a trip that afternoon and customer service could not get me a replacement phone in time. They checked the old phone's reception in the store and 4G came up, stayed connected for a minute or two, then dropped to an x without even going back to 3G. The salesguy told me he had never seen anything like that before and got me the replacement from stock. He said that 4G reception was perfect at this store, and smiled...
The new phone seemed better at first, but I had to go before I could really check it out. Then I was in a non-4G area during most of the next week and while only 3G was available the data connectivity seemed alright. Things did not look so good though when I got home to Raleigh after that. 4G never stays connected for more than a few minutes here now on this phone either. Locking it down to 3g seems to make it so at least 3g connectivity stays up reliable, but if it is set to Network Mode LTE/CDMA then it will stay briefly in 4G, maybe, and then drop to x and then maybe come back after a while to 3g, which is iffy. Meanwhile my wife's droid3 has a solid 3G connection and my tenant's S3 is solid 4G.
I tried the *#*#4636#*#* menu this afternoon and set the preferred network type to GSM auto (PRL) which is odd because my understanding it that this phone doesn't even have GSM hardware. That sets it into a 4G that seems to maybe stay connected better, maybe because it avoids switching to 3G as easily ?
I guess I will have to get another replacement and hope the new one has a .09 radio instead of the .10 radio like both have had before ?
I am wondering if this is a network type hand-off problem between 3G and 4G or something like that.

I am on .10 and havent had an issue. I got my gnex last month with 4.0.4 installed and it was fine. I then flashed the AOSP JB rom from muzzy and its been working great too. Stock kernels and radios.

In NYC. Rev. 9. No signal dropping issues at all. Completely stock, locked boot loader.

Thanks for all the replies. Looks like there are some good .10 versions out there after all.
Quick update on mine...I'm on replacement #6...or is it #7?...I've lost count. But, I know I still have the issue.
A couple of weird things though...this most recent phone was made in Korea, not China. When I opened it up and saw that I just KNEW I had a .09 version. But, alas, when I turned it on it is indeed .10. I thought all ones made in Korea were .09 and ones made in China were .10, but that doesn't appear to be the case.
And, another weird thing, this new replacement has IMM76Q on it, not 76K. I find that interesting because 76Q hasn't been pushed OTA yet that I am aware of. I actually called Verizon again yesterday and had to go through the same old song and dance with the tech guy and one of the questions he asked me was the build number. When I told him 76Q he informed me that 76Q was not the most recent update and it should be on 76K ( ). I just LOVE knowing more about their devices than they do. I had to inform him that no, 76K is the most recent OTA, but 76Q is actually more recent, just not pushed out yet. He went on to accuse me of rooting my phone (which I haven't yet since it's going back...again) and installing 76Q on it.
I freaking HATE getting "specialists" who do not know what they are talking about. I know more about this phone than they do it seems.

Glad someone brought this back up. I'm about at my wit's end, and am seriously considering their offer to send me a RAZR. Sure I can't hack it, but at least I will have a usable phone.
Just to reduce the repetetiveness I will say I ran whatever kernel came with the ROM I was using at the time. Also, I've not experiemented with the so-called "hybrid" radio sets. All 4 phones always experienced fairly weak signal when compared to my previous phone, an OG Droid. But then again my Droid could send a text message through 3 inches of steel when I was on a ship. My work is a fringe area, so I'm going to focus on the issues I have at home, where I usually get 3-4 bars. Located in Virginia, near Virginia Beach and Norfolk.

Most recent phone (received it yesterday) also came with IMM76Q. Couldn't tell you what the other's came with. I did try turning off 4G about an hour ago, and haven't had a single signal drop since then. <sigh> I totally don't consider this an acceptable solution. Time to call VZW again!

I do not have signal drops.
Except some random 3G drops in the past day or so but I do think it's a result from a dirty flash catching up with me.
Other than that, no issues.

Worst phone yet
I was having similar LTE drops with my Bionic (after I allowed the .905 OTA update). I ended up getting another Bionic and then another SIM. Didn't fix anything. It was obviously the latest build and god knows when the next Motorola update would be, so I got a GNex replacement. That was a mistake. I'm having worse issues with this phone than the Bionic. Can't hold a 4G signal to save my life. Heaven forbid I need to make a phone call, because that's unreliable also. VZW tier 2 tech said it's a known issue and an update is needed to fix it, but the ETA is unknown. She said some of them work and others don't, based on her own personal experience (her sister has a GNex). So I'm getting another Nexus to replace my replacement. We'll see if the next one is any better.

Learnt something about Canadian LTE from a buddy who works for a carrier here

So I was enjoying a cigar with a buddy who is a field tech for a Canadian carrier (not mine rogers, but another one) when we got on the topic of a samsung tablet work issued him.
He said he uses it to troubleshoot LTE issues they've been having.
Basicly the device loses LTE and either goes into "no service" or get's stuck in HSPA+.
I freaked because i've noticed the same issue, but thought it was related to CM10 running on my phone.
Apparently they discovered it has to do with they're infrastructure. The phone loses LTE, tries to re-negotiate,gets rejected, and stops trying.
They're work around is to get firmware updates to get the devices (he didn't mention which ones) to re-negotiate a second (or third time) where it almost always goes through.
I just reboot or bounce air plane mode and it often works.
Just figured people might find that interesting.

When I bought my S3 at the Bell store here in Québec city a few weeks ago, the salesmen insisted on NOT giving me a LTE sim card.
What he told me conquers with what you are describing.
I accepted is suggestion and got a H+ micro sim.
Since then, I returned to the store to get a LTE sim card and I did encounter the issue once or twice.
I am now forcing my phone to remain on H+ at best via Settings > Wireless & networks > Mobile networks > Network mode.

In the greater HRM (Halifax/Dartmouth/Bedford) we have a pretty good LTE footprint according to the Rogers website, but my S3 is constantly reconnecting. I can tell because every time it drops LTE, my visual voicemail app will notify that it has no service.
I turned LTE off because it was just hammering my battery. I could barely make it through a 10 hour work day with little to no usage if I leave LTE on, and I'm supposedly in the middle of the service area.

Off topic: CM10 has awesome battery life with LTE i find

I first read about LTE causing loss of service several months ago. I returned my first SIII because of it and the replacement phone would also loose service randomly. So now if I want to be assured that my phone is working when I really need it to, I have to disable LTE. Seems like more people need to know this since for some people it is important to know that your phone hasn't just decided to go into NO SERVICE mode without warning.
I'm told service providers were, until recently, strongly denying there is any such problem with LTE. It wasn't until the iphone5 came out with the same issue that this became a real problem for customer service.

Not sure if this is the same issue, but I sometimes receive a "not registered on network" or "sim not registered" when phone switches from LTE to 4G or comes back after being in a no service area.
A tech calls me once a week to track the issue and he told me last week they put out a fix for eastern canada and will soon do the same out west if it works. This is Telus by the way.
If you are running into what I mentioned all you have to do is switch to GSM/HSPA Auto mode under - settings/more settings/mobile network/network mode.
Of course you won't have LTE but its a reliable temp solution if you require consistent service.

MTS LTE
I've heard similar from MTS about their LTE!
My Galaxy S3 works fine on LTE, but my brother's S2 LTE never seems to display LTE on the screen, just says 4G all the time, yet speed test results indicate it really IS LTE! The first 2 weeks, his phone kept dropping to NO SERVICE randomly, but more often than not! We swapped out the LTE SIM on day 2 since the first seemed to be defective. After that, I updated the S2 to the latest release OS which seemed to have remove SOME of the issues.
From what I've heard, the LTE towers need the phone to be quiet on network activity for 20 seconds or so before it will attempt to jump back onto LTE. The S3, being much faster, doesn't seem to have issues flipping around as it needs. I'm told they are deciding which software/firmware to upgrade their towers too which will hopefully happen early 2013!
So I'm wondering if this might be the same issue with other carriers, where the problem is ACTUALLY with the towers and not devices?!

Not that stupid as I, like I said, did experience the issue since I got my LTE sim card.
But to answer your question, no I did not have to pay for the new sim card.

I've done the same. I find "4G" fast enough for the most part, so I just leave LTE off for the gain in battery life.
Also in Halifax I might add!

Rooting issue or just coincidence?

Hey guys, I just a sprint gnex phone a few weeks back and ran the GNex toolkit v9.1 to unlock and root it this past saturday so I could use a hotspot app for my tablet.
I don't know if this is just a bad coincidence or if I did something wrong..I'm not new to roms and have modded my previous phone (evo 4g) about 50 times, but here's what's happening.
Prior to this weekend I had full signal/bars..Now I can barely get 2..It's mostly sitting at 1 bar and sometimes drops the connection entirely. At the same time, every txt msg I send comes back with an error stating it did not send, however...It does actually go through, twice even. This happens with every text to every person.
I didn't put a rom on it, and I didn't even install clockwork mod...I simply just unlocked the bootloader and rooted it. I did setup google voice afterwards. I can't see how doing this would cause these kind of issues and I haven't called Sprint yet as I absolutely despise their customer service..I'd rather get feedback here first.
The coincidence that I'm referring to is that I'm in Austin, Tx and they're in the process of spinning up 4g LTE towers right now..If by chance they started upgrading my tower this weekend (yesterday & today) then I could definitely see these issues...I walked down about 2 blocks where I do get a full 4g signal, but my txting still had the same issue.
Any ideas or thoughts about my problems?

On one hand, I would tell you that rooting doesn't cause that.
On the other hand, you used a toolkit, so who knows what you ended up doing.

If you haven't changed anything as far as ROMs or mods, then I would suspect you're right about something with the network. The only other thing I can think of would be hardware problems of some kind. That seems a lot less likely though. Sprint does supposedly keep a list of networks that are being worked on. You could check in with them and see if the one in your area is being upgraded.

Reboot your phone and go to about and sprint system update.

Idk why but its sometimes happens for no reason.
Make sure you have good connection first.(go outside)
If that doesnt work update prl to make the network find the closet tower to you.

I was trying that repeatedly hoping it would fix it..but it doesn't.
On another note, today when I woke up and rebooted the phone I had full bars on 4G signal..Thought life was good and then about 5 mins later it was back to 1 bar 3G. That's the first time I've seen a 4G signal here in my apartment so I'm hoping it really is just the towers in my neighborhood being converted to 4G right now.
I've rebooted my phone 3 times now and the same occurrence happens..Full signal with 4G for a few mins, and then it drops to 1 bar 3G..Have updated my profile and PRL and tried airplane mode..Only way to get that 4G signal back is to reboot the phone..Won't stay on 4G though.

[Q] Horrible signal. My problem or Sprints?

So today I have had issues with connecting to Sprint's network. In a city near mine, they are upgrading to 4G. My phone has been going from full signal to zero signal within seconds. It is killing my battery life. I am running CM10.1 with the current nightly. I restored a previous version of CM to see if it was an issue with the ROM and I was getting the same results. Do I need to flash the radios or leave it be? Could it be because of Network Vision? Is there a way to back up my current radios in case something goes haywire?

Its most likely a carrier issue....make sure you have the most current radios installed which are FD02 if i remember correctly....other than that its a very rare occurance that software would affect your signal...probably due to the work that they are doing in the area....turn off LTE and see if the 3G signal does the same thing...good luck let us know what happens

Its sprints terrible network.

I've turned off 4g, reconnected with airplane mode, restarted my phone, fixed permissions. 3G is the same. I hardly have any service. The thing is, the past couple weeks the service here has been awesome. Then yesterday, this.

Well, I have confirmed it to be on Sprint's end. All it took was a quick drive around town to pick up a different tower. My buddy has a signal booster in his apartment and I was picking up full bars there. Here's hoping LTE is close!
