[Q] Problem With GPS

Hi guys,
ok, my GPS has not worked on my Galaxy S for a long time now. I am always flashing new roms, kernals and it may be something to do with that.
Currently I am running the MUIU Beta rom, but it hasnt worked on previous roms like Darkys.
I decided to download GPS aids from the market ro run some tests.
It downloads the LTO test file, but is unable to copy it.
It says "The application cannot copy files from SDcard to a SYSTEM folder. Maybe it is a busybox problem"
Busybox 1.18.4 is installed to /sbin/
GPS aids has superuser permissions
Google maps hasnt been able to get a fix for a long time. GPS Test cannot find any satelites.
Not sure what I did to cause this problem, but can it be fixed?
Is this a hardware issue?

I know it sounds silly, but do you have your wireless turned on when you are trying to use your GPS? After flashing to 2.2 on my Galaxy S, I found that I couldn't get a GPS lock without having my wireless turned on!
Edit: My original thread is here: http://forum.xda-developers.com/showthread.php?t=986151

Thanks for the quick answer.
Yes the Wifi is switched on, but nothing. Not even one satelite.
The funny thing is that the GPS used to work great. A lot of people werent happy with it but I had no problems.
I got a lock within 10 seconds. I just dont know what I have done to stop it working! lol

Flashing roms you may now have a bad modem or wrong set up especially as you have a beta rom and darky rom .
I would flash stock with pit 512 and reparation checked in other words build a clean phone .

Have you tried the gps test app to see if it is at least seeing the gps satellites or possibly getting a lock?

Hi, yes Ive tried that app. It doesnt find any satelites at all. Nothing!

Unfortunately, I really can't think of anything else. Sadly I believe JJEgan's advice above maybe the only other option
This thread has another possible option http://forum.xda-developers.com/showthread.php?t=974702
You may also want to check out the GPS settings on the phone. I'd have to search the forums for the code that gives you access to them.
*#*#1472365#*#* for 2.1 Eclair.
*#*#3214789650#*#* for 2.2 Froyo.

Not sure, but give this a try... my i9000 can get a gps lock in about 5 seconds with no wifi.
Download Fasterfix from the marketplace.
Run it and choose the region that you are in.
In the Location settings, turn off "Use wireless networks" and turn on "Use GPS Satellites"
Go into the LbsTestMode
*#*#1472365#*#* for 2.1 Eclair.
*#*#3214789650#*#* for 2.2 Froyo.
Application settings - Operation mode - Standalone
Application settings - Accuracy - 100
SUPL/CP Settings - Auto Config
Re-boot your phone
Go back into the LbsTestMode
Get Position Test - Let it run for at least 3 minutes while your phone is outside (clear sky view).
Delete GPS Data.
Hopefully that will work for you as well. I was unable to get a GPS lock without wifi prior to this, and now my GPS locks perfectly on its own.

Me too, i think that the gps is very poor, at least for me. Yesterday the sport tracker gps doesn´t worked fine.
Do you know if are there any fix for that?

With Android 2.3.6 i have reboots when i using my gps...i think it's a hardware Problem...

Me too, gps taking fix and then lost and repeat again... and other times woring fine. I not have idea at this
Sent from my GT-I9001

So noone using SGS+ can tell me that their phone's GPS is working properly? On any ROM (including the stock ROMs, even the branded ones)? And that apps like FasterFix do not help?

i have used FasterFix to change NTP server to europe.pool and then used GPSAids with "Other" selection in Setup, then downloaded GPS aiding data.... TRY
...for me this helps a lot.i get fix to 1 minute, and that is very good with samsung

I'm using i9001XXKP4 and the GPS takes a long time to get a fix. I was walking to work today and after about 8 minutes trying to get a fix it didn't.
When i first upgraded to i9001XXKP4 (the phone came with some 2.3.3 version i cant rememer not, bought in the UK) I noticed that the compass wasnt working and the GPS coudln't get a fix but after a reboot (i didn't reboot since installing the new version) the compass started working and the GPS got a fix while outdoors holding skill in about 2 minutes.
still compared to my previous budget ZTE blade, which got a lock in seconds, this galaxy is waaaay slow.

i've used the instructions found on the web to enable something called GPS Plus.
aparently it was a feature of the i9000 but can also be found on the i9001.
(remember, i'm on i9001XXKP4)
basically:
dial:
*#*#3214789650#*#*
this will open an activity called AngryGPS
Go to Settings> General Settings and set:
Operation Mode: MSBASED
Start mode: Hotstart
GPS Plus: ON
Accuracy: 50
then to go back to
Settings > SUPL Settings
and set:
Servert FQDN type to: Auto.
Just in you need the original settings, here they are
Server
supl.google.com
7276
UMTS SLP
OFF
SUPL
VerSign
but the software saves the original settings and changes back to the google server if you choose custom again.
Reboot the phone and that it.
It got a lock in about 20 seconds with me walking with the device in hand and eventually locked on 10 sattellites. half of them were high quality signal.
worked inside the car in my hand no problem but the signal is a little stronger if i put it below the windshield.
anyway... hope it helps.

hmm, I see what was wrong. The settings page came in front of Angry GPS so I had to quickly tap the back button twice.
(Same ROM as you, also rooted)
It works now! Thanks

Galaxy S GPS Can't find satelites

I Deffinitly Tried everything, I tried the hardware fix, Change The Pool To Israel, France, Europe, everywhere, I tried the gps doctors , nothing works..
I just can't find any satelites, in the gps aid app when i press the GPS doctor it's telling me that the gps status is off.. is there anything that I didn't try and could work?
Please, I'm Desprit..
I Tried and the problem is at every rom
I'm Right now using ICS RC3.1 By onecosmic..

try gps status , to see if is an app error from navigator and other gps programs or RC3.1 probleme , and if are ICS probleme try first to flash devil led kernel
and a wipe cache

I though onecosmic's RC 3.X was only for the i9000 and not i9001.

Well I Tried and looked at the gps status, I didn't really get what am i sepoused to do there, I reset and cleared all gps data and downloaded it after wards..
the app didn't show any errors ..

Try to get GPS Aids from market. Had the same problem and that fixed my gps

Tried the gps aids too... Ain't working.. anything else?...
When I tried the gps doctor at gps aids, it showed me that the gps mode status is not working (the cube near it is red) and after trying the setup and the fix everything possibility it still ain't working... any idea?

Try to download the GPS test and install it, then go to settings and select clear agps, then update agps.
Oh and dont try the gps inside your house! Try it in the middle of the street! Gps signal is always reeeally weak or undetectable inside a house.

Unhappy to say, still didn't work!

Can you post the exact ROM and kernel version you are using?
Also try the following. Disable wifi, reboot phone, try GPS test.
I had GPS problems a while ago and the workaround was to boot the phone with wifi disabled. Something todo with init scripts messing up GPS/BT.
When in Google maps do you get the GPS icon in the status bar when trying to GPS fix?

try this http://www.youtube.com/watch?v=STlb...xt=C3c039cbUDOEgsToPDskJOGd0pTyqyB6SPWL6OcwDB

Better to just send it back to samsung for them to fix if it's under warranty. If not, just sell it and get another one. I really like my SGS but i've given up hope for gps. I've just accepted it doesn't work and be happy the phone's great in everything else (like sound). Was kind of gutted having paid so much for a phone with a non-working gps but to be honest i have little need for a gps so when i need one i just use a dedicated one.

Now I'm using RC4.2 ICS By Onecosmic, Gps Still aint working well, I do get the gps icon... but still, my location ain't really accurate and I cant navigate or anything..
I tried the video that have been posted, None improvment...
Is there any thing else?..

The GPS issue with the i9000 is a mystery to me. I've tried software and hardware fixes to no avail with GB based ROMs. However, when I switched to Slim's ICS ROM my device started to register satelites again with the GPS test app from the market. Despite this when I open the maps app it takes forever to get a fix, so long infact that I give up long before it ever does

Same issue AOKP Milestone 4 ICS. Nothing on GPS Status.

I use market app GPS aid.

Why my GPS and location is messed up?

Hi, my hometown is in assam and i was there a few days before but after coming back here in kolkata when i open my maps or any other location based service it still shows my location back in assam. There were 2-3 times when it showed my actual position but now it doesn't anymore. What the he'll is wrong?

You should install a GPS testing program, for example GPS Essentials (https://market.android.com/details?id=com.mictale.gpsessentials ) and see if it can correctly detect the satellites and get your position.
Also, make sure you're in the open when trying to get your position, GPS doesn't work indoors, you need "clear line of sight" to the GPS satellites (so there shouldn't be anything solid above your head, for example a building or a roof).
If GPS Essentials (or any other GPS testing app) gets your position but the position itself is wrong then i really have no idea what could be wrong.
Also, you might want to try one of the GPS Fixes from the forum, they should improve the time needed to get a fix (for me it took about 3-4 minutes without the modification, now it gets a fix in less than 30 seconds).
For GPS Fixes/improvements take a look at http://forum.xda-developers.com/showthread.php?p=22798187 and http://forum.xda-developers.com/showthread.php?p=11342772

I have gps test from the market, and previously it got a perfect fix within 30 seconds from a cold start. But now the program can see 2-4 satellites max but it never gets a fix. I reseted my device twice still no help. I am really torn. I don't understand what's the problem?

[DEC.05.2011] Instantaneous GPS Fixation v1.2! *FOR ALL ANDROIDS PHONES!*
I have installed:
- Gps.conf file for asia, includes 24 countries.pool.ntp.org (includes India)
- GPS fix (Qbanin)
- SuplRootCert
it works like a charm for me... lock satelites at 2 minutes in open air (avoid buildings)
or if it doesn't work for you, look for mularameez thread
http://forum.xda-developers.com/showthread.php?t=1494862&page=2
because he's from india too, but my device cant lock sattelite with his method (Im from Indonesia)...
maybe you should try both, and see which one is the best for you

Which is the best ROM for GPS-reception?

I have big problems with gps-reception, while it worked already excellent. I don't care if it is 4.x or 5.x I liked Bliss 5.1.1 very much, but I get an accuracy of 10-20m only, when I use the gps-device only in the settings. To Test I use AndroiTS GPS Pro. I see a lot of satellites including Russian Glonass, but nevertheless the accuracy is really bad. I had a similar problem with an very old SGS+, but with a Slimkat ROM (and I found not any other ROM) I get an accuracy of 4m at the same place, at the moment with clouds after a rain.
Important for the test is, that no AGPS is used!
Maybe the reception can be improved with another kernel.
At the moment there is no working download for a Slimkat-ROM for the P880, so I could not test.
accuracy:
blisspop-v3.5-p880-unofficial-20150616-1930: 10-20m
euphoria-os-1.1-p880-unofficial-20150605: crashed after a while, only a few satellites were found, but there was a fix
aosplp-20150714-p880: No fix, found 2 satelites in 20 min.
beanstalk-4.4.4010-20140904-p880cm.: 12m
beanstalk-4.4.4010-20140904-p880cm with optimus_prime_cm11-v3.0: crash after a while, no fix, a few satellites seen
beanstalk-4.4.4010-20140904-p880cm with optimus_prime_2.7: No fix
cm-11-20140916-snapshot-m10-p880: No fix, 1 satellite seen
cm-11-20140916-snapshot-m10-p880 with optimus_prime_cm11-v3.0: No fix
IMHO this is not a hardware problem, but a software problem. Why are there so much differences in reception?

Try Omnirom, I had good results with that rom.

Could you please check the accuracy without AGPS. Go to settings and set GPS only, switch off Wifi and data and set airplane mode. Thanks! To check the accuracy you can use AndroiTS GPS Test Free. Wait about 15 min if the accuracy is constant.

I'm on Resurrection atm, I'll report back with results.

Thanks, what I found out, by searching the web, that GPS depends very on the baseband. Could you post your baseband please. I have 20A and that is probably my problem with all the ROMs.

Haha, I know your feeling regarding SGS, that phone line had a very bad GPS till SGS2. I had an SGR (same chip as SGS2) and it was really bad. Now on the S5 I've never even checked with a test app, it works perfectly even without AGPS.
It really depends on baseband a lot. I guess nobody will find a solution to the radio / baseband mystery of this phone. It's better on some roms though, but I don't know exactly as I don't use it much. Also, don't forget that if you insert headphone, it gets worse for a lot of people (for me never happened).

With slim-ariesve-4.4.2.build.5.2-unofficial-20140525-1845.zip and the SGS+ I get 4m accuracy, with a LG P880 I get 12m as best case as long as there is clear sky. I remember very good GPS reception with the Stock ROM, so I am trying to flash Stock again, where I end in errors.
