I've been using the Galaxy Nexus for about a month or so and have recently started to notice that the 4G signal will drop whenever I turn on the screen after some time in deep sleep. The signal meter will be fine, until I actually try to use some data. It typically takes about a minute to reacquire a signal, but the phone is essentially useless during that time.
As you can see in the screenshot, there are several red spots where the signal dropped out. I am not in a poor coverage area, and others with the same device do not have these issues. I saw this with a rooted 4.0.2 OTA and am still seeing it with a rooted, deodexed 4.0.4 rom (http://forum.xda-developers.com/showthread.php?t=1481613).
What do people think? Will exchanging the phone possible fix the issue? Is there anything Verizon can do to try and help me out? I'm basically just spitballing here, but this problem is making my phone very frustrating to use.
Are you rooted or stock? I don't have any issues with my 4G on stock or rooted with Gummy 0.7.6. I had an issue with an earlier root where my 4G would drop. I would disable / re-enable and it would start to work again. Maybe try rooting if you are not rooted????

Yes, I see this on rooted stock, as well as the ROM I referenced in the original post (supposedly deodexed 4.0.4 stock ROM)
EDIT: From several posts in the other thread, this issue is not isolated to me or my hardware so I probably won't bother exchanging the phone.
History of Signal ?

Can you please tell me where you get that HISTORY screen from. Ive checked all menus in settings and I can not find it anywhere.
EDIT... Please ignore my post... I found it...
So, I'm having the same exact problems but i did a log cat to see what might be culprit.
I have narrowed it down to this:
02-08 11:21:51.912 E/IMSFW (415): IIL: Disconnected from '7467' socket
still have no idea what can cause it yet.
also if you switch to 3g it seems it doesn't happen so maybe its a sim problem on verizons lte network end?
11:22:40.029 E/IMSFW (415): ImsSMSInterface: Registration failed, go for retrying if isim nounce present
that's what i found so if anyone can clarify and maybe see if it is really on Verizons end as this is the 4th phone that has had this problem.

Hey fellas, I'm posting in this thread because it relates to the issue I'm facing. Coming from the Thunderbolt, I had no problems holding onto a LTE signal in Atlanta, but with my GNex, the signal just drops a lot (every half hour or so maybe), at work, at the store, wherever. It shows an empty signal bar with a small x, and says 'Searching for Service'.
This seems to happen only when I have it in LTE mode. I switched to CDMA under the 'Mobile Networks' settings window, and it was able to hold on to the 3G signal all day. I am starting to think if it is a LTE sim card authentication issue.
I'm going to VZW to see what I can do (I'm still within the 14-day window).
I'm having the Same issue holding onto a 4g signal in Savannah and Atlanta, cdma only is fine. Let me know what Verizon tells u cause they basically told me to wait for an update

Just came back, basically they said they can't do anything unless they replicate the problem, which they couldn't. (it was a random problem.). They told me to call customer service when I got that issue, so I have to see that at work tomorrow.
I tried a suggestion online where I updated my prl from the 15xxx version to the 52642 version. I did this by creating a contact with the following number
*22899
and dialing that contact. It went through a 'activation' process, with some elevator music, and the signal seems to hold.

To this and post 10, I still have those data issues, but they are much less frequent on the 4.0.2 radio than the 4.0.4.
I got in touch with Verizon wireless online support, and they basically told me to wait till they release a software update. I asked for a new sim card (since I thought it might be LTE authentication issues), and they said it was a software problem, not a SIM problem.
I guess its a wait and see.
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.
Original Phone (bought on release day):
Reception: No major reception issues.
HW Ver: i515.09
ROM: Stock unrooted, stock rooted, GummyROM, CM9 nightlies
Radios: EK02/EK05, EK04/EK06, FA02/FA02
Replacement Phone #1:
Reception: Can hold signal for an hour or so on average. 20-40 drops per day.
HW Ver: i515.09
ROM: Stock rooted, CM9 nightlies
Radios: EK02/EK05, EK04/EK06, FA02/FA02, FC04/FC05
Replacement Phone #2:
Reception: Could not hold signal for more than 5-10 minutes. ~150 drops per day.
HW Ver: i515.10
ROM: Stock rooted, CM9 nightlies
Radios: FC04/FC05
Had the SIM card replaced at this point, while I had replacement phone #2, but it didn't make any difference.
Replacement Phone #3:
Reception: Could not hold signal for more than 5 minutes. 200+ drops per day.
HW Ver: i515.10
ROM: Stock unrooted
Radios: FC04/FC05
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.
Current Specs:
i515.10 v.FC04/FC05
Stock Kernel 3.0.8-gda6252b
build IMM76Q
On .09 / LTE and been solid all around for 7 mo's. No matter the rom, version etc.
First let me apologize if this has been answered somewhere else before, I've read at least 15/20 different threads that had an issue similar to mine but none of the fixes suggested in those threads were of any help. I cannot seem to find anything about LTE working perfectly on someone's phone then just stopping working; every thread I have found pertains to people losing LTE after flashing a new ROM or while traveling to different cities.
I have a SGH-T999L and am located in Chicago where there T-Mobile does have an active LTE network in place. I have had my phone for almost a month now and have had no problems; I have flashed several different ROMs onto it (cyanogenmod, liquid smooth, pacman) without issues as well. Early yesterday morning though my LTE suddenly stopped working. I have not updated the device or changed anything on the phone or ROM. I haven't even installed any new apps in a few days. I first called T-Mobile, they said their network is working properly in Chicago right now. After determining it wasn't a problem with the towers, I tried reflashing the modem for the device (I got it from this thread: http://forum.xda-developers.com/showthread.php?t=1880987) to no avail. Even though the IMEI was showing up properly I even did a NV restore to see if that would help, which it didn't. I then flashed the stock ROM (UVAMB7) to see if that would fix anything, however the phone is still not picking up LTE. I have even tried doing the diagnostic codes *#197328640# and according to that, the LTE radio is turned on and working properly.
As it is right now, the phone will go through periods where it cannot find any data signal for about 5 minutes at time then HPSA+15 turns on, which also confuses me as Chicago is HSPA+42 market and if I turn on my regular SGH-T999 and set it next to my SGH-T999L, it is able to pick up the HSPA+42 without a problem. Also, the phone hasn't been dropped or anything so I don't think it has to do with physical damage to the antenna or anything like that; literally I had my phone plugged in charging on the table all night and the next day the LTE had just stopped working. I have tried everything I can think of, if anyone can give me any help with this issue it would be very greatly appreciated

You might odin back to root66 and see if that works. If not, triangle away and warranty it out.
Hastily spouted for your befuddlement
start a downliad, then go to Settings, about device, status. what does it show under network type? roms dont always didplay things as we are used to. this will show your true connection.

When I do that, it shows up as UMTS until I start downloading, then it will connect to HSPA+15 then go back to UMTS once the download finishes. The phone network type used to show as LTE before I had problems, sometimes it would switch between HSPA and LTE while I was downloading or loading webpages but it would still show LTE under network type. Now it seems as though it isn't even connecting to the LTE at all.
i wouldnt worry about the hspa 42 so much. it may be the lte devices dont use it in order to save bandwidth for non lte devices. just a theory.
as for lte, you can try flashing the T999N modem to see if it helps. otherwise id agree with the other suggestion. odin flash your root66 firmware and see if it still happens. if so it may be hardware related.

Thank you, I will try flashing the modem. As for reflashing via odin, I tried doing that and the problem is still there so if flashing the modem doesn't work, I'll have to call Samsung for a warranty repair . I just wish I knew why it randomly decided to fail so I don't accidentally kill any other devices lol
Well, flashing the modem didn't work. Hopefully Samsung will be able to repair whatever is wrong with it. Thank you so much for taking the time to try to help though, I very much appreciate it
it could be something as simple as an antenna becoming disconnected, or something wrong with the radio itself. but once you are full stock, and still having issues it pretty much rules out a firmware/software type issue. Leaving the most likely cause to be one you probably couldnt fix.
just to make sure tmobile was correct, id try to go a few miles away and see if it connects though. just to be thorough.

Hi all,
I've got a sim-unlocked M919, MDL bootloader (<E modem), NB4 GSM modem. Currently running a SlimKat build from about a month ago. (Ignore my signature, as I haven't updated it yet!).
Anyway, recently I've noticed poor WIFI reception. GSM/LTE is great, no problem with cellular reception at all. The issue is only with WIFI.
It seems to be worse now than it used to be... for example right now I'm within 5 feet of my router and I'm only getting 3 bars of WIFI out of 4, and if I go a room or two further away in my house it drops to one, then disconnects if I go farther away. No other device (Cell phone, tablet) gets less than 2 bars of signal ANYWHERE in the house. I see similar issues when I have the phone in other places with wifi, so it's not just something about my house's router.
Is there something physical I can check? Loose wifi antenna connection or something like that? The wifi does "work" in that I do get data through it, if I've got at least one wifi bar. It's not completely dead.
While I don't specifically think of this as correlating with my switch of ROMs a month ago, is it at all possible that wifi reception strength could be due to something in the Slimkat, that I would need to correct?
It's not bugging me enough to do a complete flash-back-to-stock to check, but I'd like to do everything else that's lower effort.
Thanks in advance for any suggestions.
Marc
After googling around a bit, I eventually took off the covers and disconnected, reconnected the wifi antenna cable. No improvement in the reception.
I've purchased a brand new antenna for about $5, and it should be here in a week or so. I will install it and report back what happens.

Make sure your bootloader matches your modem.
Use samsung info app in play store.

My bootloader and LTE modem are MDL; been that way since I got the phone. GSM modem is at NB4 (been that way since a week after I got the phone...). The trouble with the wifi poor reception is a recent thing. Possibly associated with the switch to Slimkat but not definitely so... I just happened to notice it recently, when I was paying more attention to the phone after the Slimkat ROM installation. Seems like a hardware thing more than a software one. We'll see if swapping the antenna does it. I'd rather be out ~$5 and 10 minutes of time trying the fix as a first step, rather than doing a full ODIN back to stock and trying the latest paired bootloader/LTE modem/GSM modem (and hours to restore the phone to fully customized settings).

It won't take long to be honest. Just make a nandroid, flash full firmware, if it's not fixed, restore nandroid. If it's fixed, restore nandroid, profit. Either way you can restore it
I would rather not flash my firmware beyond 4.2.2, if I don't need to, but this will be my next step if the antenna replacement doesn't fix the issue.

Your MDL is stale, Serio 22 is on the money.

Yeah, I know, it's time to dump MDL... it just has such an air of finality about it, leaving Knox-free MDL. Not that it matters, as the warranty on this thing is presumably no longer valid (I'm second owner).
The antenna will be here in a few days, and I will give it a shot. If that doesn't do it, I'll flash the latest firmware for a test.

So, my first antenna replacement was too short. It should be about 9.5 cm long, and the antenna I received was only 8 cm. Got a refund, and ordered from a second place, that took 2 days to process / ship. But, in the end the whole thing cost me less than $4.
I received the second replacement antenna and installed it this evening. Immediately I'm getting one bar more signal everywhere I've tried the phone. So, the replacement antenna is definitely an improvement. I still think my reception isn't where it should be, and am looking forward to eventually trying to update my firmware to get latest baseband/modems/etc.. But I won't be doing that until LP ROMs have come along a bit farther. Everything is working pretty well right now with only one minor issue that pops up now and then and is easy to circumvent.
So, there definitely was a hardware issue with the antenna. It was worth a few bucks to check it out, and it's nice to see a payoff.

I have an unlocked 10 running on T-Mobile US. I previously had no problems at home with a 4G LTE connection. But after updating to 1.53.617.5 this week, my LTE signal at home has completely disappeared on me. What's worse, the phone shows full bars, and won't drop to a slower connection. I have to manually switch to 4G/WCDMA (Auto) and use the slower 4G connection, which I presume is HSDPA.
Is anyone else experiencing the same problem? I even did a factory reset, but it didn't help whatsoever.
Between this and the weak Wi-Fi, I'm starting to have second thoughts about this phone.

My LTE and wifi signal are slightly weaker on the 10 than what I'm used to seeing. Also on Tmo US. My LTE drops when I'm not upstairs lol. I took the ota when I first started up the phone so I can't speak for the other version.

Does it stay on LTE even though you have no reception? Mine does, and it also shows full bars.

Yeah mine doesn't do that. Switches to 4g
Have you tried doing a factory reset?
Maybe try wiping the cache partition? Check the "weak Wi-Fi signal" thread for directions on how to perform it. Just a suggestion.

I just tried wiping the cache partition. No dice.
I installed the OpenSignal app to see what's going on. It seems that the phone is locking onto a cell tower that's many miles away (in the middle of a river!), instead of many LTE cell towers that are only a block away from me. This makes no sense. It also indicates full reception.
The latest update definitely messed something up. Perhaps it's related to the "Wi-Fi stability enhancements".
unlocked htc 10 on tmobile. getting only 0-1 bars in my house . texts dont send and occasional dropped calls at various times. what could be the problem?

I have this problem as well, spoke to T-Mobile and of course they tried to blame it on the phone saying that they cannot guarantee that an unlocked phone will work with their network. I proceeded to tell them that the phone was listed as fully compatible with T-Mobile's LTE network they had no answer. I know it's not a solution at all but I'm on T-Mobile's prepaid service so at the beginning of next month just before I need to make a payment I'm switching to AT&T to see if that is any better
I'm somewhat disappointed and I really don't know if I should return the phone or not

While I do think the 10 doesn't get a signal as strongly as other phones do (my S6 was great), I think the latest firmware (1.53) has impacted reception for the worse.
Wait till HTC release T-Mobile RUU , you can change your mid, cid to tmo and flash it.

I shouldn't have to flash the phone to get it to work. Also, the purpose of getting the unlocked version was to have a carrier-free phone.
The more I use this phone, the more I notice that LTE connectivity is screwed up. It likes to lock onto the wrong cell towers that offer no reception (but still display full bars).
What's interesting is that when I turn on Wi-Fi, the phone locks onto the correct cell towers.
Forget the camera; HTC needs to resolve all these radio connectivity issues!

I agree the purpose of getting the unlocked phone was to not have to have a carrier branded device. I noticed that as well with the phone connecting to be incorrect tower. It really is frustrating because I've already started paying for my phone so I don't want to have to return it, I like all aspects of it physically but something has to be done about this reception. I used to get 4 to 5 bars and now I'm lucky if I get two
This is really ridiculous, I've only had my phone off the charger for just over an hour and I've used 10% of battery. I don't keep Wi-Fi on all the time I only had to turn it on to use Wi-Fi calling because my signal is so bad, HTC really needs to do something with the radios in this phone because the poor cell signal is just killing my battery life. Is anybody experiencing this same problem?
Here's a screenshot

You have a massive wake lock. Your issue doesn't reside with the radio.

Root your phone and then install better battery stats or gsam or any other utility that can show you specific wakelock stats and info. From there you can use that info to track down the specific wakelock.

Perhaps it's an app that's draining your battery.
I found that the Wi-Fi activity stat is wrong. Even on airplane mode, my 10 says that Wi-Fis active.
