Hi,
I have a strange bug I've never seen on other Androids I've been using.
When navigating with Google Maps, sometimes the GPS icon in the tray flicks out, and navigation stalls. Then, usually 5-10 seconds later, the icon appears and navigation resumes.
It happens in mapping mode too (Google Maps go from precise GPS to loose Cell/WiFi positioning), as well as other programs that try to acquire coordinates like TripAdvisor.
It's not like the GPS is losing satellites, that would make the GPS icon blink, not disappear. It's like I've disabled GPS in settings or in the power widget.
I have US AT&T Streak, unrooted, with original 1.6 firmware (6601), unlocked by Rebel SIM, using it on Fido (Canada).
I sincerely hope it's a software bug, not the problem with my particular Streak...
Comments, anyone?
Here is a post I have put up on the vodafone.IE support forum this afternoon.
http://forum.vodafone.ie/index.php?/topic/5898-samsung-galaxy-s-gps-issue/
I figured I would post here too - as maybe this will give some of you serious android programmers a clue as to where to find the issue with GPS
___________________________________________
I have experienced issues with the Galaxy S (2 weeks old - with the KIES Android 2.2 update loaded) doing Navigation,
I decided to download the FREE VERSION of application "GPS Status & Toolbox" from the Android Market to see what king of signal quality the phone was getting. The results were more than a little surprising.
The application will need GPS turned on. I turned off the "Wireless Networks" location services to make sure it was not contributing to the problem.
When you start the application, go to Menu->Settings->Display & Tools-> and select "Keep the screen on" so you can watch the satellite signals.
Now, return to the main screen, and allow the phone to pick up satellite signals. At the bottom right of the compass window it shows Fix/Sats with numbers indicating how many Satellites it has found, and how many it has managed to fix on a signal from. And, just below that there is a line of signal strength bars all the way across the screen.
Once you get enough good fixes, the signal strength bars for the fixed signals will turn green, and the phone will update your position below the compass.
Now for the fun bit....
The FREE version of this phone displays (some dubious) ads at the bottom of the screen. If you click on any one of them, it will launch an Internet Browser session over the top of the application. Immediately press the BACK button to cancel the Internet Browser, and return to watching your satellite signals. Notice that the MENU and BACK buttons will have lit up as the browser started, and will still be lit.
After approximately 3 seconds, watch the MENU and BACK buttons light go out, and at the same instant, the signal from ALL satellites will drop completely, and the phone will start scanning for satellites from scratch again.
It appears as though Samsung have inadvertently hooked the control of the power feed to the GPS chip into the same piece of logic as the power feed to the light behind the phone's buttons.
I am not sure what else can trigger the loss of signals but this appears to be a real problem.
I have verified that it is not just my phone that experiences this issue. I have replicated it on one of my colleagues phones too.
Can somebody from Vodafone please try this same test and report the results back to Samsung. It needs to be fixed urgently.
After approximately 3 seconds, watch the MENU and BACK buttons light go out, and at the same instant, the signal from ALL satellites will drop completely, and the phone will start scanning for satellites from scratch again.

I noticed a similar effect when using the GPS test app.
When you have a fix, if you turn the phone 90 deg. to 'landscape' view and then back again, it has to start again to get a lock...
Are you sure it is not a bug in the app? With GPS Test app, I have a fix, then press menu button then press the back button to hide it. 3 seconds later the button lights go out but I still have a fix.
Its a bug in the app. Same thing happens when you go to settings too. Loses a good fix.

Liverpool Fan in Dublin on Vodafone with with SGS (are you my twin??)I'm also an LFC fan in Dublin with an SGS on VF and I also have GPS issues.
Did VF ever respond to you? I've given up trying to talk to them, they really haven't a clue and don't care.
BTW, I followed the instructions on this thread to a T (http://forum.xda-developers.com/showthread.php?t=842694&highlight=dangrayorg) and I now have fast GPS fixes and pretty good Google Navigation ability. Sure the location sometimes strays 20-40 metres off the road we are heading down but it's actually pretty good bearing in mind it's a bloody phone not a dedicated car based GPS.
I'm actually quite happy with it now

So we all have issues with the i9000m and GPS (Or many of us do).
After I got my replacement hardware with a Dec date on it and when it was running 2.1 and was using whatever the version of Google maps was out at that time (Dec 24th), my phone was getting GPS lock really snappily.
After updating to JL2 of 2.2, it became unpredictable but when it was working, it was VERY fast. Two weeks later, my friend got his back and they had only replaced his mobo but he was unable to get a GPS lock in Google Maps or any Google app that used GPS.
Today, on break, after I had fiddled with my phone some this week, we tested what I was thinking of, that being: Google Maps or something with how it and 2.2 interacts is broke on our phones.
Here is what I did that was also tested and is doing the exact same thing on mine and my friends phone:
Install the Tricorder app
Reboot the phone (Either battery pull or power switch, same result)
Try to get a GPS lock in Google Maps (Our phones would time out to power save before it would get a lock)
Start Tricorder, go to the GPS/Compass section and wait for the satellite bars to turn blue
Exit Tricorder and then start Google Maps or any other Google app, the GPS lock will occur in less than 10 seconds every time
If anyone else could test this on the newer hardware or on a phone that had its mobo replaced, it would be nice to see if this is happening on more than these two phones.
And note that once I started and exited from Tricorder after it locked, all GPS apps now locked super fast.
Both our phones are running official JL2 2.2 with no rooting or whatnot.
Thanks,
Jason.
It is well known that you sometimes need more than 30 seconds (default screen off delay) to get a lock.
But if you start an application that can run in the background such as google navigation or my tracks (recording on), your GPS won't shut down when the screen turn off and you will finally get a fix if you wait long enough.
It is also well known that once you get a fix, if you loose it (by turning off your GPS app) you can get it back really quickly.
You didn't find anything special. Just leave google maps open (by pressing on the screen at least once every 30 seconds) and you will get a lock just as fast as with your tricorder app. There is no magic. You only need to leave your GPS on for long enough.
From my experience, I sometimes waited 2-3 minutes with JL2. But I don't care, as long as the GPS is accurate.
I have exactly the same lock on with Eclair > JPY > JPX > instant to about 30 seconds .
This is about the hundredth supposed fix posted .

And how is waiting in Tricorder for a GPS fix instead of Google maps a solution?
Exactly zorxd..
ok, so what if since either (can't say for sure cuz don't use gps much at all) rooting, or flashing speedmod k13e, when i pull down the tool screen and click on gps to turn it green, the gps icon does not appear at the top of the screen - i don't think it's on at all. apps like maps, gps navigator etc that use the gps don't work.
what's that about?
Hello all,
so,
I have a samsung galaxy note 3 n9005, but one thing does not work, the GPS ...:crying:
- Google MAP, with wifi or 3G / 4G I have approximate positioning.
without WiFi or mobile data, no GPS signal, but the GPS icon appears in the notification bar
I tried everything I've seen on the web, flash a new ROM, Kernel, Modem ... nothing to do.:crying::crying:
It worked very well under the official rom SFR, but nothing since. and can not go back
Currently, I can not change a Modem
It always strikes me: N9005XXUGNG1
Thank you for your help

The common fix is, rollback to stock, enable GPS, install custom rom, it'll lock...
But you're saying you can't go back!
I'm on stock though
On dialer you type in * # 0011 # this USSD
Press the menu key> press back
Press the menu key> press the key input> Q
Press the menu key> press the key input> 0000
Wait for a few seconds and the screen will change options
Press on UMTS
Press on Common
Press on NV Rebuild
Press on NV Rebuild
Press on System, Protocol, GPS, IMS
Wait for 30 seconds and then shutdown your phone
Power On phone
GPS should work fine now
Recommend to use GPS STATUS app to reset and download AGPS Date
It should not be your ROM, I mean the chance is very minimal.
As I said previously, Note 3, for whatever reason depends on A-GPS data a lot. So it's actually normal that you are not getting a lock when there's no data. Do one thing, keep the data enabled, go outside, get a strong lock. Then disable data, and see. I think it should work. Assisted GPS data doesn't stay on device for long as far as I know. I think it gets cleared up at every reboot.
Download app GPS Status. By default the A-GPS download data I think is set at 12 hours interval or something, just set it to 6 hours or something.
PS: One more thing, I found a bug while using Google Maps, I saw that the GPS icon (in status bar) kept blinking as if my GPS was still trying to get a lock. Yet in practicality the phone already got a lock! I understood that by seeing Endomondo Pro (a fitness app which I use to track my walking and cycling) was showing as "GPS excellent", while that icon kept flashing on status bar. From that day I don't believe that notification any more. I only depend on apps like GPS Status from now.
My situation is that GPS doen't work in ANY S5 port.
It works in Lollipop as well as othes kitat rom thogh. :crying:
Any idea?
Hello, I'm new to this forum and I want to know is there anyway to fix my Samsung note 3 GPS? I'm having trouble with my GPS that constantly keeps on showing "Searching using GPS". For some reason it doesn't lock my GPS to "Location is set", The Specs on my Phone is Samsung note 3 (SM-N9005), Unlocked, Region from Greece, and my android version is Lollipop. I did the most following method from researching my Note 3 issues lately and still no solution to get it fix. The result on my GPS Status&tools shows the result that my GPS shows fix 0/17 Sats.
Heres the list of what I've done.
1. opening up the back of my phone unplug my GPS and re-plug it to the mainboard
2.tighten the screws on the backside to get the 2 pins to be contacted
3.updated my phone to lollipop and I still get the same result with no GPS fixes
4.location has been set to high accuracy and already set a google location history checked.
5.Rooted my phone to fix the GPS, still no solution.
6.Disabled the mock location on developer menu.
7.Downloaded GPS Status& Tools and reset my A-GPS or download.
8.Same issue along with Kitkat update.
9.Open Google Maps as a background app
10. Updated google play services and still doesn't work.
That's all I've done. Any solution to get this fix? My carrier is T-mobile. I can still text, call, use mobile data, other than GPS.
P.S. I've been playing Pokemon GO with it. Every time I drive to a main event, my character doesn't move all it does is jump to a different street.
Thank you.

You may need to be on a stock ROM for this to work, but this is what fixed it for my N900W8 (gleaned from this thread):
1. Open the Dialer.
2. Enter *#0011# (hit the call button if nothing happens automatically)
3. Menu key -> "Back"
4. Menu key -> "Key input" -> enter Q
5. Menu key -> "Key input" -> enter 0000
Now, if you have an "UMTS" option:
6a. Tap "UMTS"
7a. Tap "NV Rebuild"
8a. Tap "NV Rebuild" again
9a. Tap "System, Protocol, GPS, IMS"
10a. Wait a minute, then reboot
If you DON'T have an UMTS option:
6b. Tap "UE settings and info"
7b. Tap "SETTING"
8b. Tap "SYSTEM"
9b. Tap "NV REBUILD"
10b. Tap "PROTOCOL, GPS, IMS"
11b. Wait a minute, then reboot
After that, GPS should work again! Note: If you're not on a stock ROM and that doesn't work, make a TWRP backup, then wipe everything but internal storage and SD, install a stock ROM (preferably not an Odin one that will overwrite recovery), follow that guide, then restore your backup but DO NOT restore EFS or Modem. Worked for me.
Reads like hardware or kernel as GPS is a kernel function .

Just recently followed your method and its not locking GPS location to set by. I am in Stock ROM, its just that I don't want to take risk of rooting my phone. Is it possible to root the phone and use the app called "Faster GPS" just to get a better GPS locking?

Strange, then. Try downloading GPS Locker, it'll show you a chart of signal strengths for each satellite. Do you get any signal to any satellite? The problem I had that my method fixed was that it was seeing the satellites, and getting green bars, but not locking on to them. If you're not getting any bars, you might need to take it apart and check on those pins again - they should be bent upward so they make good contact. Faster GPS is also good for speeding up, but I don't think it'll fix it if something's broken.

I just downloaded GPS Locker that you mentioned, it shows my GPS that its getting somewhat signal and on the top right of the gps shows I have 0 in use and 14 -15 in View.
Here's the screenshot of my phone.

Try using FasterGPS, but if that doesn't work, you may need to check the antenna again. If you're outside with a clear view of the sky and you're getting that poor of a signal, it seems like the hardware could be your problem.
In case you're using metal case, remove it.

Well... I tried FasterGPS today and well... I still cannot get a locked Gps signal. *sigh* I guess its just my hardware then... Well thank you for the help Jaitsu. No worry, I can live without the GPS as long I can use my phone as a hotspot for my other GPS devices. Will replacing the mainboard resolved everything?
Hey guys, just posted in rom section, but i will ask here also.
I have same problem with GPS. My phone finds like 25 sattelites but doasen't lock for a very long time (if it do it locks to 2 MAX 3 sattelites)
I tryed everything, screweing the screws open the back and put the antena out, i tryed with different modems, latest i flashed it's POK2...
When runned on 6.0.1 phrorensis 1.0v rom i did as i wote before, and the GPS worked great, realy in a coupple of sec. it locked 1'0-13 satelites... but than suddenly it stoped. I don't know its a rom problem, it's my phone... I also tryed variuous Kernels... always the same
So mate Try lo tie the screws, try, to open the pack and "put out" the antena "pins" if that doasent work, try to upgrade ur modem and try different kernel.
So try this ( the video is for s3 but i's simmilar for n3 )
https://www.youtube.com/watch?v=9ZKlsQF4LE8
if not try flashing new modem
https://idlekernel.com/flash-tools/firmware/
POK2. the newest is hlte_SM-N9005ZS/ ( well for my n9005)
At least you're seeing satellites... Which is more than I've got.
The latest Google Play Services has completely destroyed my GPS. It won't detect any satellites at all, and Google Play keeps scanning for Location even when every possible location setting is disabled.
Only way I can get satellites in view at all is to reboot with GPS off, then ONLY turn on the GPS. The second I select High Accuracy or Power Saving, it won't detect anything until I reboot. The seconds I open the Play Store, with or without location on, GPS is dead.
Thought it was my device dying (well, it is 3 years old), but my NotePro is doing the exact same thing since the exact same update. (It also won't detect 4G anymore, which, thankfully, isn't plaguing my Note 3....)
GPS problems - i solved it 4 me
So facing GPS problems?
I was facing it to, i tryed various things to fix it, i'did evrything i wrote down here
- Check ur csc version if it's not right you need to change it
i used https://play.google.com/store/apps/d...honeinfo&hl=sl
- try this app "FasterGPS" and insert ur location / country NEED REBOOT
https://play.google.com/store/apps/d...=org.fastergps
-Try to update modem and bootloader
https://idlekernel.com/flash-tools/firmware/
-Try different Kernels , here is the link to DL kernels (now im using Lss3.3
https://www.androidfilehost.com/?w=files&flid=34872
- if still doasent work try to open ur phone and fix the "antenas"
https://www.youtube.com/watch?v=3t9vztad58g
I did all of these things than I let the GPS turned on. It locked the sattelites now its working like a charm it locks the sattelites in a few seconds.

Okay... I've done using fasterGPS and reboot to the exact location where I'm at, already opened the Antena, but now updating the modem and boatloader for my models seems to be lost. I haven't update it yet, but which SM-n9005 do I have to update with? Turns out mine is N9005XXUGB06 for the modem or bootloader. Btw, updating Kernel from Dark lord... Which version should I go for? Because I want to stay at official lollipop update instead of rooting it along with the update. I was thinking about maybe 1.6 - 5.1?

The modem that finishes with pok2 is the layes look at the date realesd. Try kernels and u'll see wich fits for u.
Do u have problem only with locking or it doasent fint satelites at all?

I only have GPS problem with locking and Satellites not being able to find my location. This phone is international (Unlocked) and the region is located in Greece. I didn't buy it from Greece, it was bought in USA. And yes, I'll try out the kernels once, I get something done.

What is ur CSC ? What is the CSC of the system ? Mybe is there the prob ? For darklord kernel u'll need a costum rom. U can find them in n3 devolepment. I'm using the phrorensis rom mm6.0.1 Its awesome.
Tell me gps locks the sattelites after a while ot no?
Suggest you use Gps fix from the market .
Download AGPS data.
Place phone in view of the sky and wait until locks on .
