[Q] After flashing to factory default with Odin 3, GPS absolutely sucks

Am I the only one with this issue? Anyone else flashed the factory firmware/radio with odin 3 and noticed terrible GPS performance?

because stock has horrible gps issues

When you say stock has horrible GPS issues, I'm not understanding. When I first got the phone, the GPS appeared to work flawlessly. This was while the phone was stock (straight from Best Buy). But now, after flashing to the Stock rom with odin 3, which should have put the phone in the same state as it came from best buy with, the GPS is noticeably horrible. Is there something that needs to be done after flashing with odin 3?

Nope its just the way Epic is.
You may have thought you were getting outstanding gps but you weren't ,just because it starts fast doesn't mean it gets the job done as should.
After a couple times using gps satellite loc goes down the tubs...like 1 loc 26-30 meter location base.
Hopefully Sammy & Sprint release patch fast.

Okay, thanks for the response.

My phones default settings were do NOT use cellular for gps, so it took it several minutes to get location.
Wifes samsung moment gps is horrible so it was literally the first thing I checked on epic.

IIRC (from and engadget/giz article) this is a new decision by google that it must be disabled. I wouldn't be surprised if ready-now techs enabled this which might be why some people don't see an issue. In the article they claim to have established that there is no issue with the epic after enabling this.
I've had no problems personally, but I'm coming from a Treo 800w (which actually gave an error and said you couldn't use the GPS if you disabled the "Use Wireless Networks"-like setting)... LORAN is better than that things GPS.
Note this setting is different from the privacy setting(s) of allowing position information access but does still have privacy implications (if your phone still knows (kind of) where it is all the time you can't simply hide your location by disabling the GPS).

Mine was slow to connect at first but once it got locked it seems as if its faster now and extremely acurate compared to evo which I am disliking more and more by the day. Just the weight alone....hhhmmm anyone want to buy a mint condition evo? lol

[Q] Did v2.2 fix your GPS?

I was really hoping it would, but after installing Cognition v2.2 BETA5.5. my GPS is no better. I really miss this feature.
If others are having this fix theirs than I need to see about getting new hardware. If not, then ... I don't know.... Start shopping for another (not a Samsung) phone?

2.2 helped my GPS immensely though it was already decent before hand.
and not to be a PITA but the really shouldn't be in the dev forum, shoulda posted it in the Q&A one.

This belongs in general.
That aside, froyo is better than stock but not fixed.

Google maps still can't get a fix very well, but its a software issue, my tracks shows that my gps has near perfect accuracy, sensor assist in settings does not work, it only makes the run on arrow, and driving through the woods worse.
Once you get a good fix in google maps you should then get fixes faster but the initial fix may take a while. Getting a fix with other software first seems to help, but may be coincidental.
Before you go trading in the phone make sure you do a clean install, master clear in odin one click, then odin flash jf6, then upgrade, either with odin or via clockwork mod recovery.

Didn't really fix it for me. It takes a long time to get a fix and once I get it, it would lose the fix within a few seconds.
I'm not using a window mount so the GPS signal has to go through the roof of my car. That may or may not affect it.

Didn't fix it at all for me. Very frustrating.
-Can't get a lock while moving
-Can't get a lock inside
-When I do get a lock it will lose it If I start moving
-Accuracy is waaay off.

2.2 broke my GPS It pretty much worked fine before I updated... now I cant even get a lock!!!

Mine will lock fine if I'm not moving but will not work once I'm moving, so still no navigation. I've heard it works for some so I wonder if there are just alot of hardware issues or what

My advice to you guys is to learn how to tweak lbstestmode settings. You can make your gps a lot better or a lot worse with these settings. Read up on the best settings and apply them to your phone.

I gave up on my gps ... I am now "hoping" that the official release fixes it for everyone

update, i previously reported that it had more or less fixed my gps, that was with beta 4. beta 5.5 cant seem to get a fix, bad install im guessing. any number of things could be responsible. and no lbs test mode settings do not fix the gps. i almost wonder if it has something to do with titanium backup which i did not use before. its all purely speculation though.

Using Cognition Froyo 2.2 b5, GPS works almost 100% out of all the apps, google (Nav mostly)is the one with issues but very few now. It just looses me sometimes, usually when going under 20 mph but it does find me again in seconds.
I don't have a dash mount yet (due to questionable GPS) so it sits on the seat next to me in a truck, not the best. My trick is to run GPS test for a minute before I use Nav, seems to work every time. I lock on 7-10 sats in 6 or 7 seconds and they stay locked which never happened before, A lot of the time I'll be locked on 9 to 10 while moving with gps test reporting my speed within 1 mile an hour. I've also noticed that I get very few mistakes from Nav if I turn on the satellite layer, don't know why but works solidly for me when I do that.
This phone couldn't do a thing with gps before I flashed Cog's froyo and I had flashed a lot of different fixes, files, and roms almost bricking the phone a few times but nothing worked like the cognition froyo. I haven't used the jupiter v 006 files neither, no need with the gps working well.

GPS
I'm hoping that there was some parallel development going on and Samsung hasn't included a GPS fix in the leaked Froyo ROM. The GPS is pretty bad now - it's taking forever to obtain a fix again.

With 2.2, mine works fine. It takes a full minute to get a lock that status solid while in motion, but it gets a usable lock in twenty seconds. It's not as good as an iphone, but it's usable. In eclair, it's useless. Most of the time I can't get a lock at all, even if I let it try for a half hour. It will see 8 satellites and not lock a single one. In short, 2.2 has fixed my gps.

Mine has yet to have the GPS functioning well enough to use it.

No
........... 10 chars.

No, not at all.
My old ancient TMO G1 running Edge on ATT had lock on GPS 100% of the time. It was dead accurate and GPS was always on point. Can't say the same about my Captivate.
I'm on my second Captivate. I exchanged my first one thinking it was a hardware issue but alas I've given up. I flashed my phone with a couple different versions of ROMS (but not before trying the OTA Official fix before flashing any customs or rooting) it updated successfully but the GPS was still hella slow.
I'm not sure what's going on but these workarounds and everything absolutely do not work for me at all.
The only time the GPS works is when I turn Wi-Fi on, which defeats the purpose of having a wireless device in my opinion since you won't ALWAYS be around a Wi-Fi network (especially on a highway connected between the middle of nowhere) ...

I drove 450 miles with the GPS on my Captivate using Google Nav. It was pretty darn accurate. Only lost me 3 times the entire trip and by that I mean it went off onto the sideroads that ran parallel with the highway and then immediately came back. I'd have to say that 2.2 definitely fixed my GPS without a doubt.

I recently was having the crazy compass issue where it jumps back and forth. But my gps had always worked well as long as I wasn't moving to fast... I know I know. But cog 5.5 fixed my compass and improved my gps as well. Note I said improved not fixed, lol.

Will GPS ever work like it should

Iv had this phone since the day it came out... this phone is awesome in every aspect expect GPS... I had the blackberry bold 9000 and that had an excellent GPS never gave me any issues I'm really thinking of trading my captivate for a torch 9800 ... what I want to know it that is there any hope for this GPS? And when should. We expect it

In a word No. This really seems like a hardware issue. otherwise this would have been taken care of in the subsequent updates. Cappy is a great device but the gps is very hit or miss. Line of sight is very important if that is lost gps loses fix. It seems like a hardware issue no matter what software fix or setting you can use.

No

If you guys really want your gps to work there are a couple ways I have found to improve it greatly. This is as close to a fix as i can find out there, and I am somewhat happy with my gps now. I say somewhat because it really should have been totally fixed by now. I am running a i9000 rom with my lbstestmode setting stock except accuracy set to 250 which IMO only makes it lock faster and doesn't affect accuracy. I can usually get a lock accurate to 10-15 m in about 5 sec outside. Navigation tracks well I usually only have one or two hiccups on a 30 mile trip. I have been running this set up for about a month and a half so I am pretty sure it will stick. And btw my gps never got a lock stock no matter what I did if I wasn't using wireless networks. Hope this helps.

I don't think its a hardware issue. I am in Canada and the GPs has been working pretty much flawlessly on the Rogers Captivate. You can see other threads and everyone who has had a Rogers Captivate and flashed other ROMS (ie. AT&T) has noted that their GPS turned to crap.
I have had this phone for a month and the GPS has been stable and I get an accurate reading down to (5-10m) in 10 seconds or so.

I believe that it is a driver issue and how it tries to communicate with the software on our phones. Sure each ROM means different software settings, which I think helps tweak the software to work a bit better with the driver, but until they fix the communication between the broadcom chip and Samsung's (or AT&T) software, it won't work like it is supposed to. Samsung so far has only tried to fix it in their software, not the driver.
This explanation also helps explain why some GPS's are better than others. No two phones have the exact same files and settings, even from stock, which can explain variance of GPS.
However, hasn't anyone else noticed that the more we move away from Samsung/AT&T software on our phones and unlock it, the better the GPS seems to get, little by little? I believe there will be no solution from Samsung, but it will just appear in the Dev section here one day, when one person stumbles upon the real communication culprit when messing around on their system.

On perception build three rom. Did juniper fix. I get a lock in under 10 seconds even with heavy cloud cover. Tracks very well too. It can be fixed. But you have to bee willing to mess around a bit.

I'm with the OP. I love every single aspect of my phone except the GPS. I LOVE google maps and location based services on the phone. But having them all be crippled is a daily annoyance for me. One person mentioned that the Rogers Captivate works well. Has anyone tried loading a Rogers rom on an AT&T phone?
We all know that GPS issues have affected every initial launch variant of the Galaxy S phones. Is there any version of the phone out there that has gotten an update that fixed the GPS issue for EVERYONE, including TRACKING? If there is, we should be looking into that rom for a fix. If there isn't, I'd say we should be very concerend that a fix will never come.

The GPS will never ever work.

Really too bad for those out there that have GPS not working as expected...I wouldn't be happy either, but since I chgd the supl server to google I've had no problems obtaining a lock-accurate as well..

It's JUPITER, as in, the planet. I tend not to nitpick spelling or grammar but in this case it's really annoying as the first time I heard about this fix I wasted some time searching in vain for JUNIPER (which is a genus of plant), which produces no helpful hits.

I was a non-believer.... The best I ever got was on Stock JH7...
But My GPS is perfect and locks in under 3 seconds on google navigation and tracks perfectly with the Axura Rom.
Last one i tried beta4 worked perfectly. Gonna flash beta5 in the morning and test that out with a long drive tomorrow.
With Axura I have officially left eclair 2.1 in the dust and won't go back due to the over sophistication of Axura. I give it a week or two before it is clearly the most used rom on the Galaxy S line.

I will take a video of my gps and google nav with my wifes blackberry 9700 running os6.
I know my post is unbelievable.. just wait for the video footage.

Anything that incorporates the Jupiter v006 files seems to have significantly improved GPS, including Axura (I'm not 100% sure it uses the Jupiter v006 files but it sure seems like it) and Perception.
I haven't really read of anyone having significant GPS problems once they have any ROM with the Jupiter v006 tweaks or applied it manually themselves, but we'll see as time goes on.

A couple days ago I was in Perception snooping around, and found a GPS settings file in the system that had different settings than in the Jupiter006 file. The Jupiter file was in there, but this file was named something different and a different location, and it used a different supl. I was looking for something else at the time, so I mentally noted it to go back and check it out for testing, but I can't find it now, I looked for it for an hour today. :/

Hmmm..... The GPS locking on is not the problem i get locks with in seconds , what is the problem is accuracy, the gps works NEARLY flawless in locking and accuracy when on a highway or interstate but when driving in the city were streets are close to each other my location jumps around like crazy, im using AXURA beta 5 and ive tried supl.google.com with no luck thanks for all your help everyone, ill look up the Jupiter fix and see if it helps ....I'm not to good with any tweaking other then flashing and lag fix's so if someone can lead me to a tutorial on the Jupiter fix that would really help

with perception 4 i had my worst gps problems. I have had good lock times with just about ever rom including stock but with perception 4 i had difficulty acquiring locks period.
Tracking is a bigger issue. I don't believe the gps will ever track perfectly or even close to the performance that it should. Someone claimed their device tracks perfectly with auxura which i haven't tried but will....but again i am skeptical and would be curious exactly how much real-time driving navigation they have tested.
Anytime someone brings up the notion of this being at least partially a hardware issue people say that it just speculation. Asserting that it isn't is no less speculation.
With some of the beastly devices coming (as soon as january...im looking at your terminator aka olympus) not address the serious gps flaw is not good business. So i believe if it could be fixed with firmware it would have been and you wouldn't hear them use words like OPTIMIZE instead of fix/repair. Am i the only one the thinks it seems they realized they can't fix it and are just trying to hold on and sell as many as they can (several places had them free with 2year contract yesterday and this weekend) before the next serious contender hits.
I really don't care for IOS but mapquest + wife's iphone 4 is a good example of how the gps on a phone can and should function in regard to locks and excellent tracking.

would love to see this. please make sure to use a route with plenty of turns..and some portion of city navigation. I am skeptical that it will track you through every turn as a gps should. Straight line tracking isn't using a problem except for the occasional lag. The tracking problem is it has a serious issue being able to track you accurately enough to know when you had turned 50% or more of the time.
UPDATE
just flashed axura 5 so will give it a brief nav test shortly.
The aesthetics of the settings menu is very nice in this build. I wish they would give up on 3d app drawer though UGLY and SLOW.
Haven't had much time to play with it yet but will report back.

limited testing but might have to eat crow.
FRESH FLASH of AXURA 5
only a 10 mile drive but did incorporated 12-15 turns.
Lock time and accuracy when stationary was great.
Best tracking and turn by turn navigation i have had yet.
Only missed one turn and it corrected itself to actual location much quicker (before when i would turn nav would continue through the intersection and start giving verbal reroutes thinking i was on a different street and then when it would finally think it had correctly re-rerouted it would actually be running parellel to me 1 or 2 blocks off).
Taking this with a grain of salt further testing necessary as i have had promising results with fresh flashed roms before only to have them quickly go to crap within a few days testing. But this is one of the more promising so i will be staying with Axura for now.
The only gps issue that really stood out was a little bit of a lag after you had been completely stationary. Slight Lag pinpointing me on road after i pulled out of driveway and same thing when leaving grocery store parking lot.
PS - are you using the stock gps settings that came with the flash or did you modify anything.

No gps at all

This gps problem is really gettting annoying. Ive tried the method of going into the dialer and puttting in whatever number sequence but as soon as i put the last digit the whole number disappears and no menu comes up. If i go into gps test, my phone will not find any satellites at all. Id like to find a fix that is fairly simple. Not trying to flashing a new rom though. Im currently on the leaked version of froyo 2.2 rooted. Anyone got any ideas?

Try *#*#3214789650#*#*

The GPS hardware is defective in a significant number of units. I have had three Captivate phones. One was purchased the first day it was available and it had a similar GPS issue to yours. No amount of flashing or purported GPS fixes improved the GPS. The second was a replacement due to the random shutdown problem. It has a similarly broken GPS. The third was a replacement for the replacement because it also had a shutdown problem. The third was a serviced/refurbished phone and the GPS behaved completely differently. It was almost usable..! Flashing one of the recent Froyo ROMs made it work even better still.
Sorry to say, your phone's GPS will likely never work. Either demand an exchange due to the GPS failure or find another excuse to get a replacement.

there is no gps problem. this happens after you flash the infused 1.5 rom and others because it has altered settings and there must be a conflict somewhere. you can fix it by entering lbs test mode from the dialer (sgs tools will launch it but it doesnt seem to make the settings stick, you can check if the settings stick by reading /data/gps/secgps.conf in a text editor) the dialer code is *#*#3214789650#*#* it sometimes doesnt work if gps is disabled. then toggle the agps mode to something else and exit lbs, then reboot the phone. reenter lbs from the dialer toggle the settings back to stock and clear gps data. then exit lbs(use the back button not the home button. i think it writes settings on exit), see if the settings stuck (/data/gps/secgps.conf) and reenter lbs and and get position test.
it is a pain but wont normally be a problem if the phone was never messed with. gps issues are a common complaint on any smart phone regardless of manufacturer.. my iphone 3g would not work under cover, that meant no car navigation(not that the app was available for turn by turn at that time), my friend complains about his droid incredible, my other friend complains about his lg, my other friends complain about various blackberries. it is a normal complaint.

I have to admit. I've only used gps a handful of times, but I've yet to have any issues with it. I'm running Bionix Infinity at the moment and have seen nothing but excellent gps.

Wow realy infused rom issue lol? I had this phone stock for a week and gps was horrible before anyroms period if anything is a samsung thing. I came from iphone 4 which.had an impecable gps, therefore no need to blame this on any rom ive tried them all and stock its all the same

while it is true there are bad units, this can be said about any manufacturer. what i am refering to is a specific situation that i have encountered when using roms that have the modified settings to use the nokia supl server. though this server works amazingly well for some reason when you flash a rom with the changes pre set there is sometimes a conflict that prevents a lock even though 10 or more sats are in sight with strong reception. one of the users above said they say "all gps working" i am assuming that means they can see sats but get no lock and i posted a way to resolve this if it is rom related. if you have a bad phone and are sure of it im not calling you a lier, get a new one! if you dont trust samsung well the lg thrill is coming soon.

Im not sayimg that bro.i love the infused its not the roms though.it may effect settings when u flash roms but its easy fix. I get locks all the time some fast some slow but 90% of the time it locks. In a house maybe mine does but no lock at work, so yea areas ,weather, signal,device, location,etc all play factor and for me the better battery charge I have the better the locks. Im only sticking up for devs this has nothing to do with specific roms

Did you flash the gps tweak addon when installing the Infused ROM? When i did, i noticed that the settings were still on stock settings in LbsTestMode. After changing it to jz3's required settings, the lock on gps was a lot better, but accuracy is sometimes off.
Here is his thread:
forum.xda-developers.com/showthread.php?t=1107860
If you dont know how to get to LbsTestMode, i downloaded an app called Any Cut. Long press on an empty area on home or whatever. Then shortcut>any cut>Activity>LbsTestMode
After that, refer to the link above and start on step 2 (if you already have the gps tweak addon)

yeah i didnt mean to point the finger at the developer either. the mod works very well for many people but for me and a few others when reflashing you have to toggle things back and forth to get it to work, i also make a few other changes afterwards but experience varies so im not gonna push my successful settings on people. as for your experiences, well my phone is impecable anywhere i go in any weather so there may be an inconsistancy in the antennas or something. the gps works under cover on my infuse better than my iphone but oddly not better than my captivate. my captivate is less accurate and gets slowwer locks but can find me inside a building with a metal roof and in the basement of my house, this is from a phone that is supposed to be notorious for gps issues, but this is only after i changed a few settings and updated the glgps daemon with da_g's mod and did a lot of figuring out what doesn't work.

Yeah i started to see up to 8+ satellites after the fix. Before wouldnt even LOCK on lol.

I'm on my 2nd stock Infuse (only rooted) and each had the same pathetic GPS/Software lack of performance issues. It is driving me insane. I assume, based on forum threads, this is a SAMSUNG specific problem.
My old iphone4 GPS was basically perfect with almost instant satellite fixes which meant I used it for running, biking and motorcycling (in addition to car use on trips), photos, etc. Can't do this with my Samsung Infuse.

it's all subjective. it's kinda a ymmv situation but the extent of what i do is start with the mod from jz3 and delete one line in his gps.conf file that says "DEFAULT_USER_PLANE=TRUE" there is no need for this (and other additions in his file) because it will be set in secgps.conf by way of lbs test mode anyway and i dont use userplane so it might cause a conflict.
the operation mode is set to msbased and dynamic accuracy is turned off ( i just do this out of habit, it "seemed" to work on the captivate)
supl server is set to supl.nokia.com and the port set to 7275 with secure socket off and agps mode set to controlplane
i have no way to know why this works any better but it "seems" to work for me. also after some googling i found that control plane can be used for emergency location for 911 calls which is a good idea if you like hiking or 4-wheeling which i do.
i offer no guarantees that this will work better for anyone but it seems to work on my captivate and my infuse, the captivate has other mods to the jupiter.xml and an updated glgps deamon thanks to da_g's mod. the infuse should be up to date on the glgps daemon from the factory and the jupiter.xml is stock.
i can get as low as 4m locks and get locks in as few as 4 seconds to about 20-50 meters initially quickly coming down to 6-8m. most locks take under 10 seconds.

Hrmmmm....no noticeable issues here. We used the apps gps status and faster fix on some evo roms to quickly connect and it seems to work on the infuse.
I will check out the link above when i have some spare time
