[Q] GPS is broken. Need help / advice - G2 Q&A, Help & Troubleshooting

So, I've never had this type of situation happen before. I flashed Cloudy Stock version 2.1 Rom. It worked great. Then I tried navigation. Noticed there was no GPS. I downloaded a couple different apps / tools. It looks like the GPS function is working just not getting a fix. Then I flashed Cyanogenmod 11 thinking maybe it was a bug. Butttt.... It wasn't. Can anyone think of a setting, bug, or otherwise that would cause this to happen? I think I've done all the obvious stuff location settings etc...? I've never seen a situation where it just didn't work. It was working on stock and also other roms.

Same here. After i updated to kitkat 4.4.2 (first 20A, now 20D) gps stopped working. Cannot connect to any gps sattelites, only it sees them, but cannot connect. Help

So, you're not going to believe this.. I reflashed Cyanogenmod 11 and still had some gps issues. But it was spotty at the least it was still there. I put the cloudy stock back on the phone and had no GPS or rotation at all ( I am pretty sure that has something to do with the radio I flashed for AOSP for the rotation fix. Not such a big deal since I honestly like AOSP.)
Flashed back to Cyanogenmod.... So get this... I took off this nifty new aluminum bumper I recently purchased see >>>>http://www.amazon.com/gp/aw/d/B00HAJ76F6
So I've attached a couple screen shots of the differences with and without the bumper... WOW... Didn't see that coming. So, problem solved for now. I will hopefully be able to return the case. The issue with the stock lack of gps is probably due to the radio. I will deal with that later. I just need to find the right stock radio for the D801 to fix the rotation and the gps. Thanks for listening guys! Good times... :good:

GPS Problems on a new G1

I'm on my third G1. The first one died to some strange graphics issue where the screen would go completely pixilated and wacky on me. I think the graphics processor was overheating. On the second one the touch screen died about the same time the speaker in started buzzing during calls.
Luckly because TMobile extends your warranty 90 days every time you get a new phone, I've only had to pay for shipping. I got the latest one, and immediately installed Cyanogen 4.2.5 on it. No problems. Then I followed Michael Mayhew's instructions for the maps update to get Navigation.
I can't get the GPS to work at all. I've since tried going back to RC29, or the base Cyanogen 4.2.5 without the maps hack. I've tried other GPS applications such as the Chartcross GPSTest. I can't get a read at all on any of them. I don't know if it was working before the updates, because I never tried to use maps before I installed the mod.
So I'm wondering somehow a radio update was applied that broke this phone, or if there is anything I can do to change the gps drivers around. Anyone with similar GPS failure issues?
I don't really want to return this one as I've only had it one day!
Yes, similar issues. No solution thus far. I also did not test GPS before flashing. OOPS?!? And now it no longer works, but I can't tell if that was the case to begin with.
I followed the same procedure (CM 4.2.5, Navigation mod), and had the same result--broken GPS. "My Location" not working, "Searching for GPS" forever, etc.
So two possibilities I can see:
1) hardware problem w/GPS
2) one or a combination of CM 4.2.5 + Nav = broken GPS
I have seen a few people on these boards say their GPS doesn't work all of a sudden. In fact, there are stock Droid owners with issues.
Can anybody chime in?
Hmmm
So for about 10 minutes on Friday it started working again. Totally random, I have no idea why. I was at a party and decided to see if it was working. All of a sudden I had signal (using GPSTest) and google maps found my location.
I've since tried it several times, rebooting, and doing a bunch of other stuff. I can't get it working again. Total fluke! So frustrating!
Well now the new version of google maps is in the market. I've successfully installed that one but still no GPS.
Im having the same issue on my G1 right now. Sorry for the Zombie thread, but did this ever get resolved?
I've had the gps fail on my phone and others I know have also. The g1 seems to have issues with the gps antenna strip breaking internally so one minute you'll have reception, the next.. nothing. Only solution is to find a new antenna strip and replace it (good luck!)
Aside from possible hardware failures, the GPS units on these phones tend to be very weak. Sometimes it *IS* impossible to get a strong enough signal to lock on, even when out in the open if there is something nearby that can reflect the GPS signals.
However note that these are AGPS devices, which means that with a cell connection and a data connection, and given that google knows the coordinates of the cell tower you are connected to, it is able to load assistance data (almanac + accurate time synchronization via NTP), and this will *GREATLY* improve your chances of getting a good lock and greatly reduce the time it takes.

I doubt that it was the GPU overheating. Your phone would burn your hand if it got that hot.
The in-call buzzing could be corrected by shifting the screen a little bit while it is happening. It is related to GSM interference with the speaker. The speaker is literally playing the radio waves emitted by the phone. The touchscreen issue was probably a broken cable... also related to moving the screen.

What radio version are you running?
I've also had no luck getting a GPS signal ever since I installed hacked navigation... I wonder if that's the problem? Has anyone tried removing the hacked navigation, to see if that solves the problem?
BTW, the problem started on CM 4.1 with EBI0 radio (2.22.19.26I), and still persists with CM 5.0.7... Has anyone tried upgrading their radio to 2.22.23.02? How about the folks that have gone back to the Updated Rogers EBI1 Radio (3.22.26.17)?
I have been having the "searching for gps" problem as long as I can remember (although I just got this phone a month or two ago)....I remember trying to install the hacked navigation or something so maybe that messed it up?...this phone was never opened, and I would hate to have to open it up to see if it is a hardware issue because I may not put it back as it was. IDK what to do, I even started a thread about it and tried every solution I could find and nothing worked for me....
I wish someone could chime in here with some insight...but it is also nice to hear others with this issue and their advice/ideas also...
Has anyone tried un-rooting and returning the phone back to complete stock and wiping everything ? has that worked for anyone?

GPS doesn't work on Kitkat

So I installed a few different stock Kitkat roms on my note 3 (Australian version). At some stage I realised that the gps wasnt working by not getting a singal. I've gone and done many fresh installs with odin of different stock roms and still can't get it to work.
I've used gps status and after fixing a-gps data it will sometimes show many satellites on the horizon but with a very weak signals. If it does finally get a signal after a reboot it won't work again.
I've manually replaced the gps config file and it doesn't help. Also when I use an AOSP rom the gps works perfectly, locks fast and accuracy good.
Any ideas/suggestions on how to get the gps working again will be appreciated!
Not sure to be honest but I have two Notes here with different antennas (our whatever it is that sits on top of the GPS chip), running different Roms but they both seem to get into a state where they suddenly lose the signal, from 10 Satellites or so down to none, then reset GPS and eventually get it going again......could take quite some time or require reboots.
I find that X-Note (non stock kernel!) is much better but did not completely eliminate the issue.
I've rooted one of the phones so I can't return that for warranty and knowing Samsung Australia they would do nothing to help me anyway.
I'm pretty sure that ALL Notes have the issue but it seems to be random and only triggered after some time off operation.....so if you're not running GPS all the time you may not notice.

Someone has posted a gps fix zip. Which is supposed to work. I was afraid I might break something so didn't try it. I installed bob cat rom hoping that would fix it. but it didn't. Mine is international lte. So it isn't supposed to have the gps problem. Knox has tripped over so I am out of warranty. As the aosp rom works go back to that. Or just go from rom to rom till you have what you want which has gps working. I think x rom has working gps but not sure yet. Will know once installed. And i will find that gpsfix zip and install that.

That GPS fix zip is for 4.3 ONLY and will create a boot loop on 4.4.2.

Thanks, wouldn't happen to have a list of n9005 4.4.2 roms with gps fix installed would you? I think thousands of people would happily void their warranty to get it. That is the only reason I installed another rom and voided mine.
But it didn't fix the gps neither do the gps status etcetera.

Sorry but I don't. I think ALL 4.4.2 have that bug, at least all the ones I looked at. I don't know whether this is an Australian thing but it's very strange.
When it gets 'confused' the map that usually shows the satellites in view (or that should be in view) has ALL of them in one spot at the top end of the circle. A clear AGPS data usually fixes this but it sure looks like a software bug. I assume Samsung will eventually fix this. It ONLY happens certain times of the day. yesterday it did not happen before 14:30 but when it did, it did so on both Note 3 I have access to.

For me in australia with lte version it is a case of never getting enough satelites to get a fix and losing soon after. While my i9305 and my wife's n7100 both work fine all the time. So I cannot see it as just an at and t or verizon usa problem. My phone is with optus who updated the firmware as soon as I turned it on. But as I wrote no go so tried sweet, x, omega, bobcat stuck with bobcat 8 more success with gps on 8 than 9. Hopefully 10 will be more like 8. Perhaps 4.4.3 has a fix..
cheers
Curious, there seems to be a multitude of Australians with this issue..
You're going to have trouble aquiring a GPS lock these few days everywhere though. There has been a CME on 04/06/2014 (international dating) that hit Earth at 07/06/2014 and sparked a G2 geomagnetic storm. It plays havoc on all radiosignals, including GPS. It'll be bothersome for another week or two, most likely.
Gps experience with stock rom
Here is my experience in Without rooted complete stock ROM GPS Locking Time.:good:
Bought SM-N 9005 in December(U.A.E)- Jelly Bean- GPS Lock within 4 to 5 Seconds without any Help of Internet.
January Flashed Kitkat Poland (XEO) GPS Lock within 60 seconds without Internet, with Internet 30 to 40 Seconds,:crying:
April Flashed UK (BTU) GPS Lock timing same as Poland.:crying:
May Flashed U.A.E version again GPS LOCK WITHIN 4 to 5 Seconds without any Help of Internet.:good:
I am from U.A.E my question is GPS has anything to do with region? I mean GPS software is inside CSC or ROM or Kernel????
Try entering root folder and open up etc>gps.conf using text editor and change LPP_PROFILE to 3 instead of 0.
sama with me. i alteady try many rom include stock ne4 firmware. cannot lock the gps signal. felling sad.

Inaccuarte/not working location/GPS features

EDIT- Issue has been solved with the official stock OTA sprint/G900P release (currently on OT6 deoxed)! Happy to have working GPS again!
Hello!
Ever since upgrading to 5.0 (Cyanogenmod 5.0 clean flash, and then upgrade to teamub latest build 1/11) my location has not been functional. I have the sprint version galaxy S5. With the latest teamub builds, my gps has finally been 'working' when I press the location button in maps, but it thinks that im located 50 miles away from where I am. The position has changed several times to very different area's. At first it would not find the location at all, regardless of data/LTE enabled and GPS set to on with high accuracy mode enabled on MAPS settings.
I would like to clarify that this issue persisted before the dirty flash to teamub, so I do not think its a question of a clean flash. Also, I have tried clearing the data for the maps app in settings and restarting it, which did not resolve the issue.
This is a frustrating one, as I absolutely love these rom's and LP, but the GPS is one of those deal breakers for me, it must be functional.
Any advice on troubleshooting is very welcome and thank you.

I experience this exact same issue with the latest CM12 build.
If switching the setting to Device-only location (GPS) it doesn't work at all. Waze says No GPS.
On Google Maps High Accuracy location mode seem to use only Wifi and Mobile Network calculations to determine locations. GPS is broken.
Someone told me to try TopNTP to fix it, but it didn't solve the problem.
I also tried searching and found someone on OS 4.4 saying to enter the service menu with *#0011# but that doesn't work either.
Edit for clarity: I have clean flashed new CM12 builds as they become available and have had this problem with every ROM since I switched from factory TW (6 or so diff ROM's)
*build is cm-12-20150120-UNOFFICIAL-klteusc

I concur that GPS is indeed broken in CM12 as well. Even though I get the GPS icon in the corner, it appears that no applications communicate with the GPS hardware to determine location. I also have found that only high accuracy mode using WIFI + Data works.
However, since you are the only person to respond with this issue, I must assume it is working for many others.
Thanks for the info and hopefully there is a solution in the near future.
For reference, what is your hardware model # ?

Yes, hopefully we get someone with the same problem that found a fix or a dev that can look into the problem. Anyone else, please speak up.
Model: SM-G900R4
Baseband: G900R4VXU1ANG3
Just bumping this thread because no resolution has been found.
Can anyone confirm GPS device only mode works on their S5? This is a frustrating problem because sometimes I really need GPS only accuracy. If I go on a hike and there's no service/data around sometimes GPS is the only difference between me wandering in the dark at night and actually finding my camp site.
Thanks

OTA stock released for my G900P!!! Fixed my gps issue

I grabbed the full stock .tar released 2 days ago (from OTA) and odin'd the phone (after wipe) to full stock. That solved the problem (running stock official) and then flashed to deoxeded to make things snappy.

Gps wierd problems...

Hi guys
Bought this used note 3 recently. Some weeks after I bought it I noticed that my GPS was not positioning at all while I was driving, so I searched a lot and found that this model has a lot of gps problems. Since I got the cellphone with lolipop 5.0, I dont know if this issue is software or hardware related.
The wierd part is, using gps test, my device can see 30 satelites but wont use any one of them. I tried to get a fix for one hour and wont get it. I did this in an open space. I opened up my device, straighten the pins, checked the flex, and its everything ok in that department. Flashed stock rom again, flashed a custom rom, and still nothing. flashed back to stock and rebuilt the nv file, nohing... I'm cluess on what can be, since I tried anything. A-GPS is working since I get a positioning when I load google maps. (while using the gps while I drive, I cant get any fix)
I will post a print screen of gps test later since I have to go to work.
PS: Sorry for my bad english
Thanks in advance

How to fix the GPS?

Hi there,
I have a D801 I bought this summer in the US and recently I'm having problems with the GPS. I got it with stock LP, and I think back then it was working fine. Then, I started testing different roms, and at some point it broke. I guess it is a software problem, but I don't know how to fix it (I search in each rom's thread but it should be working ok).
I'm currently using this ROM http://forum.xda-developers.com/tmobile-g2/development/rom-tmo-lp-extreme-v1-0-4-16-15-t3084681
Software details: http://imgur.com/GhqDN9D
I have tried fasterGPS (to set it for Spain) https://play.google.com/store/apps/details?id=org.fastergps&hl=en and GPS Status https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2&hl=en but it takes forever to lock into a satellite (1/26), and even then it is not able to get the correct location in Google Maps (tried outdoors in several places already).
Any help? Any additional info you may need?
Thanks in advance!
i think most people who have had problems with the GPS on this phone have given up. the GPS is just flaky to non functional. There is a mod out there where you raise the antennae pins to contact the case using something to shim them. that might or might not help. I did it on my LS-980. I also did it on my Samsung Note i717 and it solved it.
I think part of the equation is software related. I updated my rom to Dirty Unicorns and my GPS was working most of the time. but when it refused to lock, nothing could make it. on stock, I had a weird condition where the GPS would work only if my phone was in 3g mode, not LTE. However, when my phone got stuck in 3g mode, would never switch back to LTE without turning off and on mobile data. I am currently back to stock but my GPS doesn;t work.

Nice... Then I'll give a look at that tutorial. I was hoping to fix it by flashing some radios/basebands or the likes, but we seem to be on the same boat. It is not that I use GPS that much, but I didn't expect such problems in a previous flagship phone. Anyways, thanks for your help :good:

Don't get your hopes up on that tutorial. GPS is notoriously bad on G2. So many people have problems. Mine doesn't work at all and I gave up like the previous poster said. Not a big deal for me except when I'm trying to use Uber!

Well, I finally had the time to try the antenna hack (https://www.youtube.com/watch?v=dfS4LpfcLfg) and it went from locking to none to locking to 12 out of 20 sats. Finally I can be happy this phone (also running CloudyG2 btw). We'll see how long does it last though...
Thank you all!
Here's a weird situation, just recently used the TOT method to restore my phone back to stock, and after installing the updates to bring me to zvh, my gps is working again. Still a little flaky but mostly working.
