Hello! I know this is a common thread, but i'm desperate!

My GPS is not locking at all, i left the phone for 10 to 20 minutes and i got nothing...

I'm using the CM10.1 MoDaCo ROM, but i tried so many ROMS, fixed configuration files, walkthroughs, etc, but none of them seem to work.

I'll list all the methods that i try so far.

1) Flash a fixed configuration file

2) Change the ROM: i tried with the stock 4.2.2, CM10, CM10.1 Nightlies, CM10.1 Experimental, MoDaCo CM10.1

3) Flash different radios. I live in Chile, so i tried UGLL1 and UGKL1

4) Clear data of Google Services Framework, restart, etc

5) Used FasterGPS to set my location in the right area

6) Used GPS Status to improve AGPS

7) Change the build.prop file

I tried every method and the combination of them, but nothing has worked for me so far....

The GPS is very important for me because i use it to track my rides with Strava, and since the GPS is not working, i cannot start the application...

I really need help...

I use a Galaxy Nexus Maguro without Wallet and live in Chile. I cannot tell exactly when the GPS started to fail, but at least in the stock 4.1.2 it was working perfect, so i guess it started failing when i updated to CM10 and then to CM10.1.....
[Samsung Galaxy Nexus] ifly4vamerica:
Ok try this if you haven't.

In settings turn off all location. Reboot

Make sure location reporting is still off.

Clear data on Maps force stop maps

Reboot

Clear data on maps and force stop again

Enable location

Get gps lock with maps or easy gps.

Might not work but I have had your same problem and this fixed it .... good luck

Hi!

Thanks for your answer, but unfortunately i've already tried this method with no succeed. I tried again but it didn't work...

Thanks anyway, i'm going to try to roll back to stock 4.1 (because the GPS was working with that version)

and if it really works i'm going to upgrade to 4.2 to see if i can find the error...

If someone else can give me a solution i'll appreciate it!
[Samsung Galaxy Nexus] pr0xyw0rm:
Flash stock, just to make sure it isn't hardware related.
[Samsung Galaxy Nexus] duqueso:
I already tried, but with Android 4.2.2 and it didn't work.

Before i flashed the 4.2.2 i was using stock 4.1 without problems, so i believe, and hope, that this is a software issue in the 4.2.2 update...

I'm going to try it now and i let you know.
[Samsung Galaxy Nexus] niamul:
My GPS got worse after upgrading to 4.2.2. Lock takes much longer and finds less satellites

- wore out your welcome
[Samsung Galaxy Nexus] duqueso:
More info

Well, i returned to Stock Android 4.1.2 using Fastboot, but the GPS didn't work either... So i updated via OTA to 4.2.2 and the GPS didn't worked again...

But i noticed that the Nexus S belonging to my sister, wich uses CyanogenMod 10, is not working either!

So i have a doubt now: Is it possible that CyanogenMod could have ruined our GPSs? If i erased everything via fastboot, is it possible that some remains of CyanogenMod could still be breaking my GPS? Or are our GPSs, strangely, broken at the same time?!

Please Help!!!

If you've flashed the Google factory image, you have an active sim card with data connection, and gps does not work, then you have a hardware problem.
[Samsung Galaxy Nexus] duqueso:
And is there a way to fix it?
[Samsung Galaxy Nexus] klobkelosh:
Out of my realm of expertise, but I imagine the sirf chipset is not user serviceable. Your best bet would be Samsung factory service. I'm sorry.
[Samsung Galaxy Nexus] duqueso:
Well, after giving up on trying to solve my GPS problem, it fixed itself.... i know that sounds weird, but the only thing that i did was update the CM10.1 to the latest RC2 and the problem was fixed, at least partially. Now it can find some satellites and it takes like 100 seconds.

The Gnex GPS isn't the best one, so it behaves a little weird some times, but at least is fixed now...

I really don't know what could be the problem, because i tried with almost any Rom, officials and no-officials...

Finally, the CM10.1 RC2 fixed my problem, hope this could help someone else.
[Samsung Galaxy Nexus] Mach3.2:
Enable wifi & mobile network location in settings

Should be some code in 4.2.2 that prevents you from getting AGPS data if you disable the said option.
[Samsung Galaxy Nexus] duqueso:
The problem is fixed now, but i tried everything, from rolling back to 4.1 official to 4.2.2 official, CM9, CM10, CM10.1, AOKP, etc. So i really don't know what could be the problem. I also tried the solution that you told me, but that didn't work either.

Right now, with CM10.1 RC2 my GPS is working great and i'm able to use Strava again.
[Samsung Galaxy Nexus] wpeen001:
I've been having the same issue. I'm running a Stock Verizon Galaxy Nexus, on my third one now. I have tried everything from apps, to resets, to disconnecting the gps, and nothing seems to work. It just seems to take forever to get a GPS lock, sometimes I just have to reset it. Not sure the issue, and I can't seem to find anyone with answers either. IDK if anyone found anything??
[Samsung Galaxy Nexus] klobkelosh:
Cold start gps can take up to 20 minutes outdoors with a clear view of the sky if you don't have current agps data. Thereafter, you should have quick starts for a day or two.

Is your data working properly? Do you have sync settings turned off?
[Samsung Galaxy Nexus] wpeen001:
My data is working just fine, I actually have great 4g where I'm at, and all my sync is turned on. I've never had GPS problems with any of my other phones. I had an EVO 3D, and it worked great, cold starts would take seconds to find GPS.
[Samsung Galaxy Nexus] klobkelosh:
And you have certified that all the gps settings/permissions are turned on? Even in the Google settings app?

Since you are stock, it might be helpful for diagnosis to preform a factory reset.

Edit - I see on another thread that you have already performed a factory reset. Next step would be to flash the factory image and see if that helps.
[Samsung Galaxy Nexus] wpeen001:
Thanks, I'll have to look up and see how to do that without root and boot loader unlocked, this is my third Galaxy Nexus from Verizon, they keep replacing it and I keep having the same issue

And yes all setting have been turned on, kind of driving me nuts
[Samsung Galaxy Nexus] klobkelosh:
I'm sorry for you. it must be very frustrating.

As far as flashing an official factory image, I think you can do it unlocked if you have adb set up. Or use a toolkit, unlock, flash factory, relock (or not, why not keep it unlocked?)
[Samsung Galaxy Nexus] wpeen001:
I'm trying to keep it locked cause if I need to use the Verizon insurance, then I believe it can't be rooted
[Samsung Galaxy Nexus] klobkelosh:
Unlocked and rooted are different things. Either way, you can unlock then relock and vz would be none the wiser.

The only time I ever had any GPS issues was when I flashed early builds of jelly bean. Otherwise, I've always had a fast acquisition (unless trying to use gps indoors)

[Samsung Galaxy Nexus] klobkelosh:
Have you flashed the factory image to rule out a hardware problem?
[Samsung Galaxy Nexus] Mr.Symbol:
Just factory reset.... But gps was working before....
[Samsung Galaxy Nexus] klobkelosh:
I'd flash the factory image then. If gps works fine afterward then you'll know it's not hardware. Of course, if it doesn't your work after flashing, you'll know it is hardware

Hmmm.... So much hassle... :(

I'll try when I'll have time.... A link with factory image, pls?

Sorted... Is not hardware problem...

Flashed stock rom and the GPS is back ;)
[Samsung Galaxy Nexus] klobkelosh:
Awesome! Glad you sorted it out!
[Samsung Galaxy Nexus] krackers:
I would like to add to the woes of this thread. My gnex takes about 5 minutes from cold gps start to lock on to 4 out of 7 satellites. Subsequent locks occur in about 10 seconds. The time goes back to 5 minutes after about 2 hours after disabling gps. In comparison my galaxy s II can lock on to about 13 out of 14 satellites (which include 3 Glonas satellites) in under 5 seconds from a super cold start (it hasn't been turned on in over 2 months!). Then again, the galaxy s II is rooted running cyanogenmod whereas my gnex is stock 4.2.2. None of the suggested fixes (toggling location settings, updating gps xtra data) work to improve gps lock speeds.
[Samsung Galaxy Nexus] klobkelosh:
Yeah, it would be nice if gnex used glonass satellites, but the chipset does not.

Your issue sounds related to agps. Have you made tweaks to your stock setup that affect gps (gps.conf edits)? When your say stock 4.2.2 do you mean you flashed a factory image? Or are you running a stock aosp build? Ota?

Either way, the advice is usually the same for this situation. Flashing a stock image helps determine if you have a hardware issue. I don't think you do, but it may be the easiest way to figure it out.
[Samsung Galaxy Nexus] krackers:
Nope, not rooted. Completely stock 4.2.2. It seems to be a LOT better today though. 11/11 satellites locked on. Weird.
[Samsung Galaxy Nexus] klobkelosh:
I think USA GPS is more reliable in the usa, but not as much in Europe. I suspect USA monkeys with the imprecision in your part of the world when it suits them. Glonass support would be good for you...
[Samsung Galaxy Nexus] krackers:
I'm actually in the US. Now the GPS is back to terrible - takes 5 minutes to get 4 out of 4 satellites locked with an accuracy of 82 feet... I think the GPS in this device is inherently terrible - just like the original galaxy S.

EDIT: I think I figured out a solution that works for me (might not work for everyone else but they are free to try). The key symptom is the gps icon not flashing when searching for signal. Simply reboot the phone and it should work fine, and should lock in under 20 seconds. This is definitely a software issue, and one that I hope will be fixed soon (along with better memory management) in 4.3/5.0.
[Samsung Galaxy Nexus] klobkelosh:
Apologies...I took your profile details as your location.

Still that's not normal behavior. I never reboot for gps issues, I don't have any and never had any. You might consider the factory image flash just to set things right.
[Samsung Galaxy Nexus] Sdobron:
I honestly only have issues like this in the summer.

I think solar flare/radiation levels have a lot to do with it. Lately, mine has had tons of odd problems (mostly intermittent) whereas previously I never had any issues.

Hello, i found the "Bug" on my Nexus 7 - and it was Hardware.

There was simple no Connection between the GPS Antenna in the Backcover and the GPS Receiver on the Mainboard.

How to fix this? Pull off the Backcover, locate the GPS Antenna. Then locate the GPS Antenna Contacts on the MAINBOARD, and bend them upwards a bit, so that they will connect to the Metall Pads in the Backcover.

Have Fun!

[Samsung Galaxy Nexus] klobkelosh:
Wow...
[Samsung Galaxy Nexus] -gb-:
Yes very strange, but i hadn't opend the Nexus 7 before so i do not understand, why there was no contact. It, the two metall connector-pins on the Mainboard, looked as if they were "normal", so i think this "Bug" may affect other Users too.
[Samsung Galaxy Nexus] klobkelosh:
Sounds like a manufacture defect.

[LG Optimus 3D] daniel.mota:
If you flashed the v30a kdz, then the problem must not be software related...

Maybe it's malfunctioning hardware...

You can partially solve it by using this:

Vol_down key to unlock

Screen Off and Lock to turn off screen and lock.

Yet, if the problem persists, you should consider sending the phone to repair.
[LG Optimus 3D] boltthrower56:
I will tell you what I told another person who was having the same problem. You should go to the LG Service center and get it replaced because you will need your power button for everything you do. You will make do by assigning your 3d button as power but still you won't be able to turn on your device.

It's not that pricy as far as I know. If you have warranty , that's even better. Install a stock ROM and take it to them.
[LG Optimus 3D] xtian63:
Power Button now wowrking

problem fixed!!! for $25

went to LGs Service Center and they said there was nothing wrong with the POWER Button, the problem was the SIM/MSDCard/Flash PCB which was shorted out and needed to be replaced because it was an its supposed to short when the O3D overheats to prevent the Mainboard from getting any damage from heat

the LG Technician said it was a built in saftey feature to prevent mjoar damage from overheating caused by things like USING YOUR PHONE WHILE CHARGING

i accidentally left the device with a game loaded while being plugged on the charger(not PC USB) and when i picked it up it was indeed hot and then it shoed the Power Menu and shut off

Hello All,

Also tried both vol up and down key + power button option. But I am unable to reboot my cell in CWM recovery mode using hardware keys. Pls help.

I have also installed ROM Manager and through it I can reboot in CWM recovery mode. But in case while flashing custom ROM something goes wrong and if I could not access the ROM manager, then I will be in no position to reboot my cell in CWM recovery mode using hardware keys.

How can I can switch back to my stock ROM?. The back up I have taken using CWM recovery options is only 26 MB. Is it correct size back up file?

I know I am posting a lot of questions, but I am a newbee and just learning these things from XDA posts. Awaiting the reply ASAP. Thanks in advance.

As you can see my above post, I am not able to boot into recovery by pressing and holding on vol+ and power key simultaneously. I tried this option when my cell had stock recovery and also after flashing it with CWM recovery. I flashed MMX a100 by CWMrecovery6.0.img posted by Aftab. However it is not working correctly and I can not take Nandroid backup with this CWM. Also CWM screen is not stable while navigating through it. Even ROM manager does not identify this as a correct CWM for Micromax A100. I dont know what to do.

I feel its not worthwhile to take a risk and flash your ROM, when there is no correct Nandroid back available for your device.

Hi all, I got the solution for this problem of rebooting into recovery. I was referring to one site where it was properly explained.

I gave up using my Alu case because of drop in power. I had seen another post from someone that changed their case but this one is really nice.

If there are any of the case makers that look at this forum then take this as a wish list of what I (we?) would like to see in the future.

[MDA II, XDA II, 2060 Accessories] thumper:
This looks really cool! Thumbs up!

The only drawback seems to be the gap between the custom case and the hardware buttons, it seems you have to put your finger (or thumb :) ) deep into the holes of the case to reach the buttons...

This is the first time I heard of casemodding a PocketPC :D I am curious if there are any other contributions!
[MDA II, XDA II, 2060 Accessories] Rudegar:
but that case is not really going to protect the screen also i doubt it would inc the signal strength all that much more then the std alu one

As the XDAII has no antenna, are there signal problem with this case ?
[MDA II, XDA II, 2060 Accessories] Camstech:
Drop in Power with XDAII and alloy case

I would have to confirm that there is most definitely a drop in signal strength when using an alloy case and the XDAII. This will be usually at least one bar on the signal meter, and can be verified by just inserting the thing and watching.

Given the lack of an external antenna, this is not surprising. I just wish I'd thought about it before lashing out 50 bucks!!! :(

The Thai casemod would help with the caller ID problem, but unless someone has delved inside the case of one of these to find the antenna then I would say that an alloy case is near useless unless you live next to a base station.

I would have thought that a well designed alloy case could include a connection to the external aerial socket on the back of the XDA with a flip up aerial on the case.....

Cheers
[MDA II, XDA II, 2060 Accessories] nargalzius:
Funny, I don't seem to have the same problem. Full signal, and still full bars after putting it in the case. But i'll try checking with Phone Dashboard as it has a percentage of the signal displayed.

In the event that there's no loss, either the new radio-stack COULD actually affect the signal performance, or you were just in a borderline signal area when you put the jacket on.

In any case, i think it's still worth it as it really protects the PDA. I mean take the free the leather case: it falls on any of it's corners, and you'll have cosmetic issues immediately.

The Alu case however, i only spotted one weak angle of falling, and its like a 1/100 chance to fall exactly like that (assuming you drop it in flat surfaces) that would have to be TOP first, and a little tilted to the back (where the SD card /antenna cover is exposed)

So overall, I think dropping a bar is worth it (if you are one of those who actually suffer from this) as you can always take out the XDAII when in critical need of signal.

Other ally case issues

The modification looks good - where can I get a Cover Pack for iPAQ 3870 ?

Another thing that would help would be to use voice dialling - because the modification still doesn't help for making a call, unless you have dialled it before closing the case. However, I can't seem to find a voice dialling setting. Is there one?

The other problem with the case is it taking two hands to open. Please let me know if you find one that has a nice swish press-catch that can be operated with one hand... Also one that you can put in the cradle while in its case

There is also a strand about the case in 'Using it'. W were talking about how slippery the case is, and raises the likelihood of dropping it in the first place. Someone suggests something from Egrips.com that will help...

Incidentally, I don't lose any signal bars with it in the case.
