Hey guys, I just got my Captivate during Black Friday, and the GPS was working pretty well in the stock ROM.
It's now running Axura CE RC1 with the RedSoul theme, and I noticed that the GPS doesn't work at all. The Samsung GPSRestoreApp keeps failing to get a position fix, and although I tried a whole bunch of GPS fixes, my phone doesn't get a position fix at all, even if I leave the GPSTest app running for more than 10 minutes.
Is there anything I can do to get a working position fix?
Please help me out, and thanks in advance!
Try a differnet rom, Axura is dead anyway. http://forum.xda-developers.com/showthread.php?t=848671

actually axura has returned from the dead.
for whats its worth i experienced nearly the opposite.
With stock i generally got decent locks (seeing 9-12 sats and usually locking 6-7). Tracking was useless and did not work other than following a straight line and it was often pathetic in even tracking straight line position/progress.
Axura 5 is the only rom that has improved my devices tracking/turn by turn navigation to a usable and actually pretty damn good state (also improved my locks....could still usually see 9-12 but was usually getting 10/10 or 9/10 consistent locks). Right now i am back on stock jh7 though...had done so preparing for the official froyo release to at least take it for a test drive. Have it set up pretty much how i wanted and alot of apps so i am gonna hold out for a bit before flashing back to a custom but if i do axura will be on my list of choices due to the gps performance i got with it.
You can look for the file GPSJM9.zip on the XDA forum, I applied on my Captivate and since then my GPS works fine (10 sec for a lock)
Flash with CWM
Thanks for the zip, i'll try flash it when i have time
Good morning guys,
I've tried every 'fix' under the sun to make my GPS work 'better' (takes 5 minutes to lock my loc), but to no avail.
(I'm on Scott's amazing CM10 JB rom)
Is every JB rom having these issues? Would it be better to just goto ICS?
I travel for work, so Maps is my best friend lol
Thanks in advance,

Scotts latest CM10 initial locked for me in 1 minute 24 seconds.
So, GPS isn't broken across the board. Sometimes there are issues, and sometimes it works fine, but by and large, the issues are local to the individual user.
If GPS is that important, I would suggest that you go back to stock and work your way up. Or just stick with stock.
Understand a solution is important, however not a good idea to create duplicate threads.

I love the work scott has done, and i realize it isn't across the board. It just stinks that I can't use his masterpiece as a daily driver

use cm9. every jb rom on this phone has issues with agps. weird thing is it is running but not helping to find sats. with gps.conf mods even the "use ref loc" feature seems to work which is network triangulation to help it figure out a rough location for a starting point but the phone still seems to use the standalone gps to find sats.... i tried logging it but nothing really gave me a clue to the actual problem. the gps isn't broken but it doesn't work so well for most of us without agps working to it's full potential.
It works well in ICS. Currently running cm and GPS locks in less than a minute.
In jb it would take 20+ minutes and sometimes say I was a mile away.
GPS has always been bad as far as I'm concerned. I've actually had better luck with the JB roms from late August onward than I have with Froyo or Gingerbread. Have you actually been able to rely on GPS for directions with this phone? I always end up having to ask at a gas station!

Turn off Google location. It might be nice to have Google now but its the worst for navigation. You need real GPS location for maps. Problem is that with jb agps doesn't work correctly so the GPS lock takes forever, leave GPS on with the screen on for another 15 minutes after the first loc for the ephemeris data to download. that should last a few days before you have to do it again.
ICS on the other hand has absolutely impeccable GPS performance for me. Much better than what came from Samsung on my phone.
Cypher rom
I used Cypher rom, and it has great GPS lock.

first of all, i appreciate that GPS works fine for some people -- why are you reading this thread then?
i'm not even going to list everything i've done to troubleshoot, but before you say 'people posting things and not checking it out themselves' i can tell you that i have tried EVERYTHING, spent hours working on the GPS issue with my phone and come to the conclusion that JB does not have proper GPS on SOME infuse phones, whether it be by region or some latent hardware defect that the ICS or GB roms compensate for, my GPS dosen't lock. i've been through like 20 gps.conf files, read about every setting in the file and tried every variation thereof, gone back to GB, gone to ICS, back to JB, multiple times, testing the result, my phone locks in 5 seconds in ICS or GB, not in JB. had same results in cm10, cypher, remICS, th3bills aokp, his miui, etc...
if my hardware was bad, i wouldnt lock in 5 seconds in GB.
one of my pet peeves is everytime you ask a question in a forum being told you're in the wrong thread when it would have taken less time to provide a helpful answer. posts telling people to move to another forum are also noise, and then further posts telling people they didn't try hard enough, or 'mine works so you're wrong' are also just noise, and not helpful to anyone. the other pet peeve is being told, after spending hours working on an issue, to stop whining because it's being worked on, when you were just trying to help in the first place. or when you read the first sentence of my post and tell me to do something i clearly stated i had already tried in my post.
nobody is whining, we just use infuse phones, and like our GPS to work.
also to be clear this isnt really directed at atrix4nag in a negative way, i just happened to reply to his message.
The GPS takes 5 minutes to lock, and it does it at 1600 meters (un)accuracy.
It behaves like this no matter what rom i try (Sky, Slim, CM9/10, Embryo etc), except for stock Rogers ICS.
The agps patch and other gps patches on XDA didn't do anything.
When i first bought it, it had stock Rogers ICS and GPS worked perfectly, never mind the fact that i live in EU.
Then i tried custom roms and it started to funk around and has been doing as long as i run a custom rom.
Today i installed Rogers ICS as a last resort and suddenly the GPS locks in seconds and with great accuracy too (9 meters).
And so the question, what the hell is causing this?
OR
How do i make the GPS work with the custom roms?
I have been running custom ROM's since a day after I got my Skyrocket, and the AGPS patch has never failed to work for me. I have been running CM10 for pretty much the last 4+ months, and GPS always works. Not sure what your issue might be.
You can flash agps patch from Boombah's aroma installer. Always works for me

I'm not sure either.. The phone is canadian with a Rogers brand on battery cover. When i install a stock AT&T rom the GPS more or less dies.
Any other rom and the GPS dies. Stock Rogers ICS rom and voila works like a clockwork.
And it doesn't react at all to any GPS patch, and i've tried like 10 different ones. aGPS is not new to me, i've successfully used it on other phones. But for some reason it doesn't do anything for my Skyrocket.

Thanks i'll try that, just don't see how Aroma is going to help if it's the same patch i've tried earlier.
On the other hand, with ghouly issues like this who knows what might help and what won't ?
Worst case scenario is that i'll be stuck with Rogers FW if i want working GPS, which is acceptable with some tweaks especially the Droid Razr M launcher

Did u by any chance leave location access for Google apps disabled? If u did on AOSP ROMs GPS will never lock

Nope, it's always turned on.
If SW doesn't solve/change anything - where might the problem be? Yes, that's right, it's probably in HW!
Check your GPS antenna contacts (antenna is inside the inner plastic, the one you see when you open back cover and remove the battery). Bend them a bit and clean their contact points to make sure they contact well.
If your phone is still within warranty or the above doesn't help - replace it.

Hi Jack_R1
Software does indeed solve everything. In short: stock rogers ics rom = perfect gps, custom rom/stock at&t rom= no gps.
Oops. Guess I skipped some lines reading the OP - returned and found your line talking about it. Sorry about that.
Did you try reinstalling custom ROMs after you got quick lock on stock ROM, to test that the issue remains?
I'd suggest a couple of things:
1. Try installing AT&T ICS ROM for testing. If it also gives you a good lock - you'll have better reference point.
2. Look at the APN you use in Rogers' ROM and in other ROMs. If you're using automatic ones - they might be different and include GPS-related stuff (type "supl").
3. Copy stock gps.conf from Rojers and try using it on custom ROMs.
4. Download FasterFix and try choosing different NTP pools.
5. Download GPS Status & Toolbox, see what exactly happens when you run it, describe here. What satellites are you seeing (numbers), how much time after running it, in which condition, etc.

1 The AT&T roms didn't give me an adequate lock, until the JB updates were leaked & released.
2 I'm always using automatic APN's but they don't have any GPS info.
Haven't tried #3..
4 FasterFix didn't help.
5 GPS Status shows 4-7 satellites and only 2-3 locks with horrible accuracy. The thing is now i get perfect locks with any ROMs.. I could've disallowed Google Services to use GPS as I might've confused it with Google Search & Ads wanting my location..
Thanks for your help :good:
I am using AOKP rom, and my GPS is not working properly. The particular issue, however, is somewhat different from what I could find on this forum. In my case, the GPS cannot keep lock on the satellites for more than a couple of seconds. It can lock to 7-10 satellites quite quickly, but then it loses lock on them and then has to spend several seconds relocking. This cycle goes on while the GPS is being used. So, I can find my current position without a problem, but the lack of permanent lock makes it very hard to use navigation.
I have tried many "fixes" mostly dealing with gps.conf modification, but none of them could solve my short-lived lock problem. When I reverted back to stock Gingerbread, the GPS could keep lock without a problem, so I could track my continuous movements within 3 meters accuracy. I tried using gps.conf from Gingerbread in AOKP, but the problem was still there. So, I can only assume that the problem lies with the kernel itself.
So, my question is what 4.1.2 Jelly Bean kernel would you suggest me to try? I really like AOKP rom, but as far as kernel goes, I am open to any suggestions. I really want to be able to use the navigation again I would appreciate any inputs.

As development on 4.1.2 is dead, you could try a 4.3 rom since theres a few to try. If not i would simply revert back to gb. Idk how accurate you need it to be, but i use my navigation on carbon 4.3 without a hitch.
Well, anything you can suggest from 4.3 that would be as stable as AOKP 4.1.2? I have been using it for almost a year, so I can't really go back to GB. If it was not this GPS issue, I would be using my current 4.1.2 until I get a new phone. Just like I will be using Ubuntu 12.04 until I need to buy a new laptop

These 4.3 ROMs are moving towards stable at tremendous speeds. Take your pick
I'm not saying they have no bugs at all, but I've been using 4.3 daily for about a month now with no serious issues

Of all the roms that I've tried, most boasted of a fast GPS lock. It was anything but. Heck, even my old Samsung Galaxy Y gets faster GPS lock. Is it a software problem or a hardware one? Also, does this phone even include a compass? When I DO finally get a lock or use my wifi, I notice that the phone has no sense of direction. Is there an alternative?
I'm never buying from Micromax again.

First of all, Trying new ROM's involves risk! Do not blame Micromax, it's you who made the modifications! if you don't like the ROM's, Go back to Stock JB 4.1! Problem is with your knowledge, and unawareness, not Hardware nor Software.
As for your GPS issue, there are various patches for GPS, you can try that, I'm running UltrimSLIM ROM and having no such problem whatsoever, after flashing a GPS patch!
And our phone does not include compass so there will be no 'Sense of direction'!

I think it was implied that I moved from a stock ROM none of which have fixed the GPS. Its not that I don't like the custom ROMs. I love some of them. I've been trying many to see which one is able to get a lock as fast as most other phones do. Hence, my question.
Is there a problem with the drivers or any part of the software that the devs haven't modded yet? I'm not a very advanced coder so I can't really help yet. Yes, I've flashed patches. To no avail. I have to wait for over 2 minutes with turbo GPS 2 installed.
Another big question is: Why did micromax release a very buggy firmware and not take steps to fix it? 4.1 has memory issues AND GPS lock problem. 4.0 was alright with memory but not GPS. Who knows how 4.4 will be once they FINALLY release it?

Ah, that's what troubling me too!! Read lots of news, posts still no sight of KK. Some fake Firmwares are out there and that's all! And yes, Memory Issues were present in stock firmware!!
But I have to admit that I used Stock JB for 2-3 months and GPS was working fine for me! I even downloaded Sygic Maps that time and since, it became my favorite!
Why don't you try that app and also see YGPS from Engg. mode to see if you are getting a weak signal or no signal at all!
I shall try that then. Thanks
