[GPS issue] Slow to no GPS... Ready to give up.. Maybe - Samsung Galaxy Nexus

Ever since flashing to JB my GPS is not working properly anymore...even tried going back to stock ICS and still no go. I know this is a known issue apparently, I've done plenty of research, tried a few fixes and nothing.
I really like this phone, but I also need a reliable GPS.
On CM10 I get a blinking icon and if I'm lucky get a lock after a minute, if not it will just blink forever.
On maddoggin I get no blinking icon at all and maybe get a lock after a reboot, otherwise nothing. On other ROMs it's pretty much the same thing. Before all this I was getting 3-4 second locks indoors.
Something is definitely wrong with it, missing files, wrong files , who knows...
Anybody have some suggestions on what to try? I'll give to this weekend, if I can't find a fix I'll just buy a different phone at this point.....
TIA!

Tried flashing JB factory images for your device? Does logcat provide any clues?

Where would I get JB factory images at? So far the only roms I've flashed are Maddoggin's, CM10 JellyBro, and BlackBean.
Thanks

AFAIK there are no Google factory inmages for the Sprint GN

Ah yes, I forgot. Google dropped support. How about suggestion #2 then (logcat)?

Same problem for me on gnex gsm tmobile. Gps was perfect before 4.1.1 now it has gotten pretty unreliable I thought it was that solar flare thing a few weeks ago but I'm still having the problem.

I did the ota update to JB and also had slow locks (like up to a minute, not as bad as some complained about). Different ROMs were about the same, until rasbean. Now my GPS performs as it did on ICS, coincidence? Perhaps. I may never know as I'm liable to stay on rasbean for a long long time.

Maybe detective hardware? Go back to stop and take it to a repair store.

I finally caught the problem: GSM carrier (AT&T in my case)!
Actually all remedies barely work on my GSM Galaxy Nexus ordered from play store. I even flashed back to 4.1.2 factory image and it did not help either. If you are like me, simply take the SIM card out and see if it locates much faster (<1min for first lock and <10s thereon).
In terms of GPS first lock, "No SIM" better than "with SIM but airplane mode" better than "phone signal on". In some locations (e.g. Centre PA) GSM signal does not bother that much but in some other locations (e.g. Baltimore MD; Cape Cod, MA) the GSM signal is a real killer.
There is definitely some kernel/baseband problem! I am just providing as much information as I can to assist professional troubleshooting to this annoying problem.

GPS All of a Sudden Not Locking

Out of nowhere, my GSM Galaxy Nexus (stock JB) won't lock onto any satellites. It literally started happening out of nowhere. I navigated fine somewhere, did nothing to my phone, and on the way home I couldn't get a lock. Actually, I FINALLY got a lock after about 20 minutes, but I've been unable to get a lock since.
I reset and redownloaded agps data using GPS Test, and nothing. I also cleared data and cache in maps, and pulled the battery. GPS Test shows that the phone quickly sees 7 to 11 satellites, but none in use.
Any ideas? I'm really stumped. What could have caused this? Should my next step be flashing a different radio, reflashing JB, or anything else? Help!

Same here tried multiple roms and no luck. But be something universal... server or similar
Same here. I just noticed this yesterday.
It actually will lock for me but it would take like 3+ minutes using the GPS test app.

Very interesting. Did it just start last night as well? At least this would indicate it's not a hardware problem.
Also, for what it's worth, the GPS is working fine on my buddy's Nexus 7 and my wife's Verizon galaxy nexus.

Bizarre...this happened to me as well...GPS Test would indicate that the phone was seeing 7-8 satellites, but would take forever to lock, if at all. At the time I was playing with Tasker and automating some GPS actions, so I thought maybe I screwed something up. GPS lock seems a bit better today, but still not as good as before
While GPS test for me would take a few minutes before any lock, Google map will seemingly to get 0 lock no matter how long I wait.
I had my nexus 7 next to my phone yesterday. I started Google map on my galaxy nexus for 5 min or so with no lock but the nexus 7 only took 5 sec to get a lock.

This definitely happend to both me and my girlfriend just yesterday evening! I did nothing, neither did she. I'm running JellyBelly v3, she's on stock Jelly Bean.
in GPS Test app, both of us can see 8-9 sats, but get 0 locks.
I've tried editing gps.conf file on both phones, no luck.
I've reflashed my ROM 3 times, no luck.
I have no idea what's going on here, I thought it was just us until I read this thread!
so glad I'm not going insane....
Now to just find a fix
Same thing for me... No gps for navigated today..
Also news and weather won't connect to the server either... All happened at the same time
I was wondering if I had a defective unit. GPS sucks on the Nexus. On my Note, it locks within a few seconds.

I agree that the GN GPS is not as strong as some other devices, but it's never performed as bad as it did yesterday. This is really curious that the problem was this widespread. Maybe some solar flares yesterday that impacted some weaker performing devices like the GN?

solar flare
Solar Flare messes with the GPS on some device, if not all the devices..
It locks on my nexus in just a few seconds as well... normally. Ever since yesterday evening, Google maps and Nav never get a lock regardless of location or amount of time I wait. The nexus has a pretty crappy Wi-Fi radio, but the GPS has previously been pretty stellar. I'd like a word on what's going on here.
Also, I just tried to lock with my galaxy tab and my friends stratosphere and neither of them are getting locks as of yesterday. Can Samsung have screwed something up?

Had the same issue last night and it continued to this morning; but it seems to be fixed now. Was not getting GPS lock, downloaded GPS Status, let it run and it locked after like 3-4 mins. Since then its locking fine like before.
This is great. I was getting really worried my gps radio was screwed up, but there's obviously some type of server side problem. I wonder what the hell it is though, since other Android devices and CDMA Galaxy Nexus devices are working fine.

Verizon 4.0.4/4.0.5 Radio intermittent signal loss

I am on my sixth nexus. I am running Vicious's 4.1.1 rom rooted and not running any weird power saving apps and turning off my wifi when not at home. The radio signal either turns off completely for a few seconds or cannot connect to data services constantly when trying to use the phone. There is nothing I am doing that creates this problem consistently. It is random. Sometimes i can make a call and talk for an hour and have no problems sometimes i can be in the same area and make a call and it continually drops the call after a few seconds to a few minutes. 4g rarely works though it shows its connected. I am running what i believe to be the latest radio for verizon I515.10V.FC04/I515.FC05. I am open to suggestions on radio's app's anything to get this corrected. I even tried going back to stock and letting Verizon update the phones to start and the problem still persists. i travel a lot and it does not seem to do it in any area more than another. but It has become a constant nu sense when talking to my customers on the phone. or trying to connect to data services. PLEASE HELP

Look under your battery. Is your nexus made in China or Korea? Korea ones generally are much more reliable

Dropped calls running AOKP

I'm wondering if this is a ROM problem or problem with my local Verizon service.
I'm getting very frequent dropped calls. In the Seattle area we have 4g service, I'm running AOKP Toro jb milestone 1.
Service drops to 0 bars, then after several seconds, comes back. Generally to show 3 bars of 4G service.
I was contemplating going back to stock to see if the problem is the same. But I thought I'd post here first to see if it may be a ROM problem.
Any ideas?
Thanks, RWM
I would use the new radios FG02. This might help. Helps with spotty transitions of 4G lte to 3G.
Sent from my Galaxy Nexus using xda premium
Mods please move this thread to general
If 4g drops to no signal and then comes back it could be hardware related. If you have the latest radios on your phone and this still happens you may need to get a replacement phone. If you take it to Verizon they'll probably try to swap the SIM first.
To return to Verizon do you think I should go back to stock first?

I would to be safe. If you're returning it, use the factory image and relock the bootloader.
I've had this issue too but only on AOKP milestone 1...dunno what it is. I've noticed when it happens "system ui" fails which has also happened when using the phone.
I haven't dropped any calls, but I get data drops every now and then.
Sent from my Galaxy Nexus using xda premium
I have this same issue, it only happens when I have good signal, when my signal is weak it's fine, it's only when I have strong signal or 4g, I assume it's a hardware issue at least for myself, because I haven't noticed a difference with different roms

Welcome to the Android Community. For sure you will find the answer to all your questions regarding android in these forums. With that said, make you read before you post. It makes you look like a noob and rightly so. This is for the Development Contribution alone. This should have been posted in the Q&A or General forum.. BTW your device is deffective- return it until you get a good one. It took me 5 times. Talk to Tech Support Level 2 when you call Verizon no one else.
Hey was wondering if you ever figured out this issue, im having the same problems only mine drops the call every 30 exactly. If i use the phone for say 28 minutes then the next call will drop in 2 min to finish out the original 30. I have been having this problem for awhile but was never this predictable, gone through many different radios, roms, eery did a factory wipe with a full wipe of everything and reinstalled xenonHD rom build number JOP40G. Please any help would be awesome. Thanks Also in the seattle area.

Hi, I am running AOKP JB 4.2 milestone 2 on my Galaxy Nexus and experiencing the same problem. My calls dropped after some time between 5 an 30 minutes with "Out of area service" alert. I am from the Czech Republic using Vodafone. I tried getRIL to install matching RIL (baseband i9250XXKK1), but this did not help. Before this I was running old AOKP ICS 4.0 without any problem. Does anyone have an idea, how to solve this problem?
Thank you very much.

SOLUTION: I finally found out a solution for my problem. I reflashed radio firmware to the new version (i9250XXLJ1) and installed matching RIL using GetRIL. Now everything works without any problem.

Can you burn your radios?

It looks like I may have done it again. On my first galaxy nexus I had it for over a year and then all of a sudden I had no signal and whenever I tried to call I got a mobile network not available. Now it has happened again. Can the radios malfunction for no reason or is flashing Roms too much a bad thing for it. Just trying to get more info on it since googling did yield much help...thnx in advance

I'd like to know too, since this is pretty much what happened to me. I "only" flashed 12 times total. I am under the impression that the NAND memory is good for a couple of hundred writes.
Yea its pretty weird and I'll say maybe random but it all ready happened twice. Not sure if its only an issue with Verizon galaxy nexus or all of them but right now I'm in the process of unrooting and relocking.

It could also be your ROM/Kernel combination. Might try changing ROM's and/or Kernels to see if that helps. Our phones can be temperamental sometimes
I flashed more than 100 times now, ans no problems here...

I flashed two different roms after seeing my signal dead and nothing. This morning i went back to stock 4.1.1 and still nothing. Its all good since i allready called verizon and they are sending me a replacement but i just cant believe this has happened twice in my last two nexus devices.

yea i had my nexus since launch day and rooted it and started flashing in about a week. but after 13 months of constant flashing whether it be nightlies or major updates, the signal just burned out or something, not really sure what happened. When i went to a verizon store they were clueless as always (but to be fair its not like i brought up the fact that i was rooted or anything so they had no idea) and gave me a replacement and in one week the same thing happened again, just want to find out if it is possible to burn the radios or if its an LTE radio burn out?
So I'm guessing its a very rare thing to burn the radios.

Zero Bars in my House

Hi guys,
My Galaxy Nexus running stock 4.2.2 started getting zero bars reception in my house in about mid December. At the time, I hadn't done anything different to it, so I assumed it would go away over time, so I focused on my final exams instead. Flash forward to today, it's been months since I have had reception on my phone. This is a really big problem for me, as I can't even take phone calls or send/receive texts. I've been using Rogers One Number and Whatsapp through WiFi to get by, and it sucks.
My brother has the same phone, and I helped him flash the Google stock ROM, so hes running same everything as me. I've tried plugging his Sim into mine and my phone still gets zero bars (his is fine). I've tried plugging my Sim into an old Samsung dumbphone, and it was fine. I don't remember if I tried my brothers phone... I will if I have to.
I had no problems for the months I owned the phone leading to December (since about March last year). I've tried scouring the forums for solutions, but I get flooded with Verizon reception problems... I'm in Canada on Rogers, and had my phone working well until December, so it's not the right problem.
According to the secret menu, it says I have -107dBm (fluctuating to -111dBm within the typing of this message), 1 asu. I have no idea what that means, but I see everyone always posting this with reception issues. I've tried doing a backup and a factory reset, with no results. I've tried flashing to stock 4.1 with no results. This leads me to believe it's a hardware issue, so I tried opening it up to see if the antenna was loose; it was not.
Please tell me what kind of additional information I need to provide for you guys to try to help me. Am I supposed to try flashing a new radio? Which am I supposed to use if I'm in Vancouver, BC on Rogers?
I found this forum (http://forum.xda-developers.com/showthread.php?t=2163312&page=), with a magical solution of waiting the next day. Unfortunately, I've been waiting for months.
Regards,
Eddy.

There was also this incident that happened last year that I posted about, but it quickly went away after the "squeeze" solution. I've tried the squeeze solution since then, and even opening it up to check the antenna with no results.

Sounds like a hardware issue. If its within warranty, have it replaced or do an insurance claim if you have it.

Unfortunately, I have neither options, as I purchased it new through Craigslist. I'm capable of opening it up, and would be happy to replace parts... does anyone know where I can find out what parts I would need in such a scenario as well as where I could purchase?

Take a look to ifixit teardown if you want to know which part is changeable
