So I've got one of the many Vibrants with the flaky GPS, and none of the fixes out there seem to improve the problem. My local T-Mo store is understanding and quite willing to swap it with a new one since I'm still within the 14 day policy. The only catch is I want to put the phone as close to stock as possible before I do the trade so they can't say it was something I did to it. Right now I've rooted deodexed, and I've got clockwork ROM manager going. I've also deleted almost all the stock cruft and swapped the calendar / camera apps. Because I was so eager to make it "mine", I also failed to make any backups BUT my wife happens to have a totally stock SGS from which I can scavange from but I'd like to do it without having to root it or anything. Is this possible? If not would thread 739091 ("True Stock 2.1 firmware for vibrant"; sorry I can't post links since my account here is still new) get me there?
http://forum.xda-developers.com/showthread.php?t=734475&highlight=stock is what you're looking for. Just flash this with Odin and you'll be fully unrooted.
Awesome, I really appreciate that. I'm not timid when it comes to making the phone my own (I was an early adopter of CyanogenMod for my old G1) but I just returned from a deployment and the whole 'scene' has changed a lot more than I expected lol.
Hehe. you might want to give the new T-Mobile Vibrant firmware that was leaked, it fixes the GPS problem (result may vary). Returning your SGS for a new one isn't going to fix your problem. It's not hardware related, its firmware.
An exchange won't fix your GPS issues anyway so you mine as well keep the one you have. Trust me, we try to swap them out customers all the time at my store.... It's a known issue and Samsung is SUPPOSED to be sending us an OTA soon

Hmmm, quite a few people I'd talked with locally that have the vibrant said swapping worked for them. Is it possible that newer firmware has been released for phones with a newer "birth" date than mine? Then again who should I trust more, people who hardly utilize their phones, or the people who drool over the prospect of new mods and hacks? hehe. I guess I'll just call T-Mo back and let them know I wont be bothering with a swap after all.

Hey, my pleasure. If nothing else, I have the Army to thank for bringing me out to Hawai'i and giving me the chance to meet my now wife hehe.
ALL out of the box Vibrant's have the same firmware. You need to update to the newest firmware version, it works really well. GPS is better than it is on my CLIQ.
I dunno, i've heard reports of GPS working perfect out of the box for some, and the new firmware doesn't seem to do much for my GPS,
10m accuracy at most unless I leave gps on for about an hour and maybe i'll get 6-7m accuracy, but driving, it SKIPS, (still at 10m) instead of gliding along like my G1 did.
So i'm considering perhaps swapping mine.

10M of accuracy is not bad and if you want to get technical, GMaps interprets the data differently. What shows in GMaps as 10 meters will show up as 7 under GPS test. I've got my Vibrant here at 6 Meters under GPSTest and 10 under GMaps. Get a grip people.

I wont speak for Qwerty, but in my case I was LUCKY to get 10m accuracy; usually the best I could get was 40m; usually after 5-10 minutes of 'searching' and when you're driving an unfamiliar city such as Washington DC Like I was this past week, 40m is far too inaccurate for navigation. Your 'get a grip' is completely tasteless and uncalled for in this thread.
That said, I took zephiK's advice and just flashed the new 2.1 (thread 780935), and I must say its a lot better. I can get a 10m fix indoors in less than 5 seconds from a cold start (EG without GMaps knowing where I am at all); before being indoors I would never get less than a 1000m 'fix'. As soon as I get mine fully tweaked, I'll be sure to flash my wifes phone as well since she's got the same issue.

Yeah, i'm still considering doing the swap, sometime this week, perhaps even today, got up this morning, and phone was off, (Charging Battery Symbol on the screen),
I'm not running any of the custom roms nor am i OCing. Just worried if I do the swap I may end up with even more problems. I don't know what it is with the Samsung phones, if perhaps a lot of the phones have hardware problems or what. I have only used the original stock rom, and the leaked samsung rom.
I don't mean to be picky with my phone, but I remember my 2 year old G1 getting easily 3m lock as soon as i open up the maps inside my room, and navigating with it, was extremely accurate as well. I also never had restart issues with the phone, till after dropping the thing really hard, and then even the restart thing went away.
Today, I'm lucky to get even 40m lock again, on that same leaked updated firmware. My gripe with the samsung vibrant is that there seems to be some sort of hardware problem with the phone and samsung is not saying a thing about it.
I'm telling you guys... don't bother with a swap... I work in a very high volume store and have seen almost every customer come back with GPS issues. We won't even swap them anymore for customers because TMO has listed it as a known issue, and Samsung has announced the firmware update soon... A swap WILL NOT fix the issue, but if you decide to swap it, don't go whining to us our TMO about how you "keep exchanging it and none of them work..." They know this, and YOU know it.
Since I reported the GPS issue to Orange, I have received 2 replacements. This afternoon I updated my SGS to latest JPA firmware and went out to test the GPS. Now I can confirm that the GPS issue cannot be fixed by any kind of software firmware update. I've tested JF1,JF3,JF7,JH3,JPM,JM1,JP3,JPA. I have used GOOGLE MAPS, NDRIVE,IGO MY WAY, COPILOT on all these firmwares. On the 3 SGS I have (an original one from contract upgrade and 2 replacements since I reported the GPS issue to Orange), with all types of firmwares, navigation softwares, none gives stable GPS navigation. There are always 2 issues:
1. accuracy. never stop showing me on a different street.
2. GPS LAG. showed me stay still while I was moving. When turning in a cross, always lag till I passed the cross.
I have contacted Samsung mobile UK to report the GPS performance on latest firmware. This time they have no excuse at all to avoid admitting the GPS problem.
I will also contact Orange for a solution. I will ask for a different phone. Hopefully they have Desire HD. Or I may consider cancelling the contract and leave Orange...
Anyone claims a great GPS improvement after JPA update, if you had poor performance before, please go test it fully, see if you have the same issue I had. If you do, you can join me ask a refund from your retailer.
UPDATE: Just now went out for a little walk, use my tracks to track my movement. Was very surprised! the JPO firmware gives a great improvement. check it here:
http://maps.google.com/maps/ms?hl=e...53.466879,-2.220461&spn=0.00213,0.006539&z=18
remember this is by walk and i can confirm this is pretty much the way I passed by. During the walk I stayed on the pavement. On Cavanagh Close I went from left side pavement to right side pavement, made a U turn and walked back to Lauderdale Crescent. Note that my end point was on Lauderdale Crescent,not Wilson St. This isn't perfect, but it's a great improvement! The accuracy is the only issue I'm concerned now. Also some reported after 10ish minutes navigation it would lose signal all the sudden. I can't confirm this coz my track only took around 5 mins. Need further test!
Has there been any revision when it comes to the gps hardware or do (should) all, even those straight out the factory now, i9000 have problems?

I have a serious question here about the GPS issue. I am really starting to think that this GPS issue is somthing that is being manipulated by specific "carriers" so that if you are a big GPS user you will us the "carrier specific" GPS app like TeleNav.
The reason I wonder this is because as I read the threads I see tht people with "unbranded" phones do not seem to have as much GPS issues as those with branded ones.
As I read the new froyo posts I see that those who have upgraded through Kies "officially" (and there by are unbranded) are reporting that GPS is locking onto 7 - 8 satelites in under 30 seconds and get a PERFECT positioning while those who have used the reg. hack method (and there by are branded) still report that the GPS is horrible.
I may be way off here and dont mean to sound all "conspiracy theory" or anything but this is just my 2 cents. What do you think?

This is a complete guess on my part, but I would think the unbranded phones come off a different line then then branded phones.
Also, the folks reporting their GPS fixed might need to wait a few days to see if it still works. It's happened before where someone reports their GPS working after a flash, to later say it was broken again.

all my 3 phones have no problem in finding satellites,they can find 7-8 satellites within 30 secs outdoor, only the accuracy is a big issue. also during navigation it seemed keep the lock very well, yet the navigation software actually lost signal and started repositioning, then reroute and ask me to turn around again and again.
branded and unbranded? My first 2 phones came without any network brand, no simlock, non branded firmware. I suppose they are unbranded? the final one came with simlock and orange official firmware. they all have the same issue. this means you theory is very doubtable.

exactly.
Branded or unbranded, luckily I have had both. all the 3 phones have crappy GPS. I doubt that at early producing stage they didn't realise the GPS problem and kept producing for a coupla months, then they found out and made some changes durling later producing. this can explain my case because all the 3 phones are produced on first quarter 2010 (JAN-MAR), the latest ones would have no problem at all.
Its definatly not a crap gps broadcom supplied the chip but its up to the manufacturer to write the drivers. unfortunatly samsung has failed miserably.

I didn't mean crap gps chip, I mean maybe the gps signal is poor due to some crappy design. or maybe you are right, samsung didn't write a proper driver. but i doubt this coz even a crappy little company could have worked out some solution after 6 months. still no luck means it's more than just driver issue.
This GPS thing is simply ridiculous. I can't believe Samsung could launch his top of the line phone with such a bug, and worse of all, I can't believe they haven't been able to solve it several months later.
People reporting the problem fixed with every firmware update, and people reporting the GPS working well when they haven't even tested it properly are also of no help whatsoever for the Galaxy S users and for themselves.
I think we should start complaining massively to Samsung since the phone is definately faulty. I think that'd be the only way we, Galaxy S users would get a properly working GPS.
You drive to slow!!
But you've experienced navigating with your cellphone on other phones before?

My old Samsung Omnia GPS works perfectly. Actually I keep that phone on my car since my Galaxy S GPS is completely worthless and able to guide nothing.
Ah good then you must atleast admit that the sgs is way faster on the fix, and the accuracy, .. well, .. it wasn't that noticable on the tomtom, igo8, sygic and stuff available for the windows mobile 6.5.3 or less, right?
The omnia had hickups, for instance; tomtom placed you back about a 50 meter and jumped back again, that's not how navigational software should work.
Even after the omnia you knew that there was something wrong with samsung's idea how a gps should function, you needing to mod or translate the gps with gps-mod, gpsgate or gpsproxy.
So this is really a step forward!
Yeah, the Galaxy is faster at fixing but, accuracy?? As soon as I start moving the damn thing keeps pointing me all over the place. Teletransporting me from one street to the other. The Galaxy GPS is simply a useless joke.
The Omnia's GPS was far from perfect but at least it gets the job done. Maybe Tomtom didn't work properly, but all other navigation softwares I've teste do work properly. Now I use iGo and it guides me flawlessly, even into the city driving thru narrow streets. I WISH THE GALAXY S HAD A GPS AS UNPERFECT AS THE OMNIA!!!
I think it's just pathetic the way the SGS GPS performs, even compared with other presumably flawed GPS like the Omnia one. Wich makes the Galaxy even more pathetic since its GPS can't even compare to other below average old hardware.
Honestly, I don't get it. I don't understand peoplo who defend Samsung on this matter, unless either, they were lucky and got a better phone than those who complain, or unless the work for Samsung and don't dare telling things the way they are.
using google maps on x10 my gps was perfect, quick lock, great accuracy and would hold connection with satellites. x10 wouldn't hold 3g connection for me.which is more important than gps.
sgs doesn't seem to be able to hold its connection with satellites, that's my problem anyway. oh, and when it does hold it seems to "drift" slowly away from my location to other streets. as in car nav its pretty useless!
I'm on jm1 fw from o2, waiting for an update, either 2.2 or a later 2.1.

Big deal, that's not the issue, the phone still fails to find enough sats in-car or inside buildings and still keeps losing the lock and I've tried four of them now.
And please don't tell me thats normal, because it's not, my HTC Legend gets 10 locks in less then 30s, inside or outside and I don't lose them.

Mmmm, do you have read all the post or do you have stopped right here?
I've had my generic handset since march and can honestly say I have never had any issues whatsoever with gps, I use navigon software and it never skips a beat I've done tons of journeys near and far and I think its absolutely fine.
Over the past weeks I've also changed firmware a few times and currently iam using jpo froyo, the only issue I have had has been with the accuracy of the compass apps but since downloading"travel compass " its been ok.

I have now installed the free maps from orange on my phone which is part of my plan (generic handset) and did around 60 miles on call out this morning and my gps was pefect as with the navigon software , i wonder if this problem is related to provider handsets and google software or there are lots of faulty handsets out there .
I ran mine side by side with my tom tom 530 this morning and while it wasnt as smooth it was just as accurate .
Im using jpo/jpp on orange uk. Flashed it last week. My gps is excellent locks on very quick and works well with google maps. Its the only software i have flashed that works well gps wise. Locks on quicker than my tom tom. Its a great improvement over the other 2.2 and 2.1 releases official and unofficial.

A GPS is supposed to give position and speed when moving, so to test it you'd need to log those two eh?
Some of us here (maybe more elsewhere) have reported their GPS as "Working Well" with track recorded to coroborate the statements. How the hell do you wan to argue with someone that puts the proof in front of your eyes? Are you so blinded by your "hatred" that you can't accept that some SGS might work perfectly well?
Come on now, if you'd realy want some "improvement" with your issue, you'd get some facts and compare them, surely there's a reason why some works and some don't. We need to find THIS reason instead of argueing pointlessly...
I just recently received a new Captivate today through the ATT insurance program that came preloaded with the JH7 Eclair build. The first feature that I was anxious about testing was the GPS since myself and others on this forum seemed to experience difficulty applying the OTA update from ATT. I drove an estimated 20 miles in the city and 15 miles on highway and noticed that I no longer experienced lag when making turns, or when I came to a complete stop and the navigation icon never jumped to adjacent streets or went over a 10m accuracy. I also was able to get a lock in 3-5 seconds while going 70MPH during my highway drive. When I returned home I rooted my phone and made a Nandroid backup and proceeded to flash cognition 2.4.1. Once I did this I decided to test the GPS again with a custom ROM installed and noticed that the GPS issues that I had previously experienced with my old phone were present once again. So after I tested the GPS on Cognition, I decided to restore to my original firmware and the GPS accuracy was restored to the favorable results as previously mentioned. What I am asking the community as well as the devlopers at XDA is if I provide you with my Nandroid backup files, would this be helpful in solving the GPS issues once and for all? I am just uncertain if maybe newer phones that came preloaded with JH7 may have different GPS settings than the OTA updates.
If the developers would like my Nandroid backup please just ask and I will upload.
UPDATE*
Here is the image file of the stock JH7 that has given me VERY accurate GPS results from the previous stated post. This is from a Nandroid backup and I do not know how you would go about installing this but I'm sure someone from here does and will test it. This has not been tested yet, but I respectfully challenge the developers and community to try this out to see if it is an improvement. This is an Eclair JH7 rom. Thank you for your time.

UPDATE 2**
I went on about a 30 minute trip and here are my results
http://maps.google.com/maps/ms?ie=UTF8&hl=en&msa=0&msid=114887993519189258855.000494f37559dc102964c&t=h&z=12
** Please note you will need to zoom in to notice all of the turns that I made. I also made a U-turn and traveled on some of the same roads in opposite directions. Everything is just as accurate as the day before.
UPDATE 3***
I would like to extend my thanks to mattbeau for trying this out and posting his results. The results furthermore prove my hypothesis and are consistent with my results. I requested mattbeau to post detailed instructions on how to flash it so others can try. Please I encourage others to give this a try the more tests we gather the easier it will be for the Developers to find what makes this different.
mattbeau My Tracks: http://maps.google.com/maps/ms?msa=0&msid=208605913791985313826.000494f74ae16f5e33c81
UPDATE 4****
Very special thank to mattbeau for posting instructions on how to get this to work. Still need a few more people to test this but so far this is the most accurate the GPS has ever been on the Captivate here it is:
download the following: http://www.multiupload.com/CB5PFRTRYF
extract with winrar or what ever you want
so this is what is working for me.
ensure the clockwork update.zip is insalled on the root of your internal SD card
create a folder /sdcard/clockworkmod/backup/jh7gps/
copy system.img and nandroid.md5 to the above folder
Oneclick back to JF6
enable debugging under settings
using adb
adb restart recovery
select reinstall packages
(it will install teh clockwork recovery)
again select reinstall packages
select advanced restore
select jh7gps
select restore system
select yes
your phone will reboot with the new system.img installed
baseband is still jf6
If I could as that everyone that tries this please post their results. The more consistent this is the more things we can rule out.
UPDATE 5*****
I apologize that the megauploads links it temporarily unavailable. We are currently working on getting this back up as soon as possible. Also will be posting my My Tracks for day 3 shortly as well. I encourage anyone else to post their results as well.
Here is mattbeau's link that was originally on megauploads. Since some of you were having problems I moved it to here:
http://www.multiupload.com/CB5PFRTRYF
Let me know how this works out. I thank all of you for your assistance.
UPDATE 6******
Here is the My Tracks for the third day of testing. GPS accuracy does not appear to be deteriorating and have consistent results from previous tracks. This is looking more and more promising by the day. Comments are welcome!

Thank you mattbeau for your thorough comparison to other JH7 ROMs. Please keep us all posted on your findings.
Some people think that 2.4 caused GPS issues that were worse than stock. I'm not necessarily saying where I stand on the issue - but your decreased performance may just help prove that 2.4 is bad at GPS.
I feel skeptical that Samsung would have a different OTA JH7 and in store JH7 and what I said above sounds like a better idea. Hmm maybe I should go to an earlier version.... helpful either way!

I am definitely not certain as well, but the GPS performance that I am experiencing with this new phone is up to par with my Garmin. More notably, I have had my old captivate since early August and have tried out all official updates on it including JH7 that don't even compare to the perfect performance this one has. I am just trying to see if I could give my Nandroid backup to someone that knows more than I do and possibly solve this issue for custom rom development etc...
Wait a few days, if you still have awesome GPS then there might be something to it. I highly doubt it though.
Swyping...please read slowly!
im not sure about this although there quite possibly could be a combination of hardware and software. my wifes phone works perfectly with gps and we got ours at the same time but my gps has been horrible since day one but we use hers and no lag, jumping off the roads or anything
Here is one result for today will post at least one everyday for consistency.

ive had 4 captivates so far. me and my wifes original 2 and 2 replacements. all 4 have been the same where sometimes there dead on accurate, and they might be like this for a week. then one day they might take 10 min. to get a lock where the day before it would lock instantly. overall id say the gps on all the phones ive had werent horrible, but could be better. im to the point now that i think its just a hardware issue, and no matter what settings we put in or what we change, the gps just isnt going to be perfect.

I would love to have a copy I just want a working phone
OP, so many of us are so over this GPS issue with these otherwise very nice performing phones. It's just a damn shame that Samsung let this line go to market with this type of problem. That being said, I, for one, appreciate those that continue to try to find a way to resolve this issue. I am one of those that read CLShortfuse's complete write-up on this matter and form that I feel pretty certain it is NOT a hardware issue; the same chip is used in other devices without issue. I think that the issue is with Samsung's coding and, perhaps, the placement of the chip in the phone.
I see a lot of notes about quick locks, slow locks, etc....the real issue is tracking, not locking. I have found that even my Garmin can take over a minute to lock, depending on where I am in the city (elevation, hills, etc.) and also is sometimes affected by weather. I've waited over 5 minutes for my Garmin to lock (only a few times) but when it does it stays locked and my tracking is very good. However, even my Garmin will loose me for a few seconds, especially when taking a ramp that it didn't expect me to (not the route it planned for me). Unfortunately, neither of my 2 Captivates worked this way. It's perplexing and frustrating. I can tell you that the fastest locks I ever got were immediately following the OTA update (I got mine through Kies Mini). Unfortunately, I flashed another ROM before I tested the tracking.
I hope some devs out there will take your offer seriously and take apart your backup, if possible.
I am going to upload the file once I have a friend with a captivate try it out first.
I agree with boomerod - remember the biggest problem for us is the losing a lock part mid-trip

I would think the first step would be to have someone with gps issues flash your nandroid. If that makes their gps perfect as you report, then it may be worth investigating further... just my .02

are you kidding me??? zoom in on that track map, and you will see it takes you off the road all over the place. Accuracy is still horrible. I have never ever seen a phone go off track like that so dont tell us to "live with it". It may look good zoomed out but try actually looking closely at that and tell us it is perfect
Well buddy17, if you do look closely at that map you will notice that it is off less than 5 meters for the short period of time that it was off. Most GPS software maps auto lock onto streets when they are that close but when using My Tracks it does not. I am almost certain it is impossible to have GPS that is spot on all the time and this could also be due to the inaccuracy of Google My Tracks. If you would post your results I am sure you would see a significant difference in tracking.
Also the GPS performance on this firmware seems to not have the "turn lag" or movement while being stopped issues that I have previously experienced as well as what others have reported. I am almost done uploading and all I am respectfully requesting from the community is to try it out and see what happens please. I would like to thank the community for their time and effort to make our captivate have the best experience possible.
Another useless thread of gps nonsense...lol. I cant believe I even looked. Shame on me

I think more or less the shame is on you for posting.
On a side note:
OP I just got a new one today too from the warranty dept. The GPS While driving is nothing but flawless. Thank you for reporting this to us, and I am a 2nd to agree how amazing the mid drive is. Showed me on the road i was on the entire time. And didn't loose a lock.
UPDATE**
Here is the image file of the stock JH7 that has given me VERY accurate GPS results from the previous stated post. This is from a Nandroid backup and I do not know how you would go about installing this but I'm sure someone from here does and will test it. This has not been tested yet, but I respectfully challenge the developers and community to try this out to see if it is an improvement. This is an Eclair JH7 rom. Thank you for your time.
Update links are on first post
I agree with the others, this thread is a waste of time. Your software image is no different then the other 500,000 JH7 phones leaving the factory or that had the update. If Samsung made a fix, we would see a different version number.
They don't just replace files and leave the version numbers the same - that would be a support nightmare.
If someone was interested, they would just compare your files to another set and look for differences; BUT, because everyone else knows that files don't get changed without creating a new build, they are not going to spend time on your challenge.
Thought i'd post these here. Others can post theres as well. If I get any answers I'll post those here also.
1. Are there plans to fix the gps issues on the epic? Or is it simply hardware related?
2. Why did samsung choose the rfs file system?
3. What is Samsung's corporate position on open-source software development?

Some people have gps issues such as accuracy i believe. some don't
Oh ok thanx just curious because me and my wife both have the epic and both are fine.

I have a problem where the gps doesn't lock at random. Usually a battery pull clears the problem. Accuracy is usually within 30 feet or so.
Rfs? It was the thing they had at the time. On new phones they are using ext4.
Supposedly 2.2.1 official on Monday will address GPS.... we will see... not sure the point of that Q&A at this time (the next few days) as we have yet to see what they listened to for the build they are dropping in a few days. I honestly think he wants our input on matters other than software/hardware complaints that are well known. I think that will be useful if everyone is contented with the 2.2.1 release, Its not a bad thing to have a suggestion box, IF the issues are addressed somewhat promptly...
I asked:
Does Samsung intend to address the hardware keyboard issue that causes the phone to miss keystrokes?
and
one other question that I completely forgot.
Edit: strike that, just remembered.
Is Samsung going to offer firmware updates for the Camera which is available in the settings menu of the leaked 2.2 rom??

Gps locks fine and quickly, but then loses lock after 5-15 minutes. You have to manually turn the gps on and off again to get it to re lock.
And I asked because it was supposed to be addressed in an update that came our months ago but still happens for a lot of us.

Dont forget you cant lock GPS with wifi or 4g on.
Well there must be enough wrong with GPS for them to mention it as one of the main features of the udpate to happen monday... hopefully they will fix your issues, I have got my GPS to 2 meters on DK28, but actually have yet to leave it on for an extended period of time, dont really use Nav, I know my city from jobs... and dont really like leaving that on, Ive disabled it since they first came in phones... tinfoil hat and all...
HW Keyboard!!! If it does not improve, I will take it in for service. I got a replacement like Jan 3, for my OG that I had since launch week, and aside from the screen fail, my original never dropped keys... not that I can remember... it also seems to be getting worse, and since January I have not gotten that much faster at typing on it to make a difference that way... but I HOPE its software... else I may end up with another TEP claim.

My question is what is samsung's plans for future os updates for the epic?

From the sound of it, Svetius at captivate says that xda will be filtering the questions before they go to Sammy.

I can probably easily tell you how they will answer it or at least summarize it..

We chose RFS for its reliability (they made RFS themselves they are not going to say any bad about it)

Those will be your answers..in a fancier manner..
As for GPS locking , I lock just fine..I noticed Google Maps gets stuck here and there but if I use any other software there is no issue...

Generally not for long. Leave WiFi on for 2 days, without ever shutting it off. Then try getting a lock. Promise you won't be able to.
I've never had problems locking on to GPS
The problem that I share with many others is that the GPS will randomly stop connecting with satellites after 10-20 minutes of use. Sometimes a lot sooner than that. It'll reconnect after about 2 minutes, but its really annoying when you're using google nav.
I've tried using GPS status and I can see that it has a great signal, but it won't connect to a couple of sats at random times. Very buggy.
AFTER the update, if it happens, those with GPS issues should get an ALL GPS thread like the 2.2 one... it seems like a real clusterfuk as it stands, and theres no clear proof that its software, or a crappy GPS radio, and thats the end of the story. After the update, which claims to address GPS, those with GPS issues need to compare notes, and figure out as best as possible what is hardware limitation, what is software, what is user error. As stated above, other software besides google maps should be tried as well, in case there is something weird happening with that... I dont use GPS much, so I wonder why this issue keeps popping up so much, and people dont collaborate enough on solving the issue. After that best GPS fix ever thread popped up, I Odin'ed to DI18, and did all the steps, even considered going to DG27 or whatever to be extra retentive, but once I got all the way up to my rooted, rom'd setup, got 2 meters, or maybe 1... thats all I bothered with. I understand those that use their epics as a tom-tom need much higher standards of connectivity.... hopefully you wont be disappointed.
I hope so too. I work at several different locations and user the phone as nav. Gps locks fine, just loses lock soon enough, often at critical times...

I just want to throw this out there.
I love this rom. I've been experimenting with all the newer roms, 2.2.1, 2.3.2 etc etc. It seems like I have real problems with the gps navigation with the newer roms. So I reinstalled this rom to test it out and I had forgot how well this rom works. The gps connected quickly, no problems at all. Not having gps navigation was bugging the sh** it out me, so thank God this is a steady Rom to go back to.
