Captivate with JH7 GPS testing - Captivate General

Just loaded the official JH7 release and took my scooter for a ride. Captivate in my left front pants pocket, so it sits face down on my thigh, back (battery) side facing up toward the sky. Actually, it looks very good. Before the ride, lock was very good, lots of satellites and all locked very quickly. And the track looks excellent. I'll be curious how this works in a week... whether it degrades as the other one appeared to. But at the moment I am tentatively happy. Note the scooter ride averaged 20.82 mph, max speed of 38. So this was not a slow walking track. And yes I went up and down those blocks making a pattern to test the GPS. ;-)
Please post your test results of JH7 in this thread so we can compare.

I am in no way trying to be disrespectful, or an a$$ even though the following may seem like I am:
Did you search the forums before posting this? I started a thread similar to this not 20 minutes ago. I personally do not care to be the OP but I am posting here to explain that this is the reason we 2312 different threads about the same dang thing (today's update). It is impossible to search for information because everyone seems to feel the need to post their own thread.
Again no disrespect, I am not trying to dampen your enthusiasm for this but just would like some organization so that people (me ) won't have to read 30 different threads to get some information. I will ask the XDA gods to merge our threads maybe???

I was looking for a thread like this not 15 minutes ago. Finding it in this cluster of posts isn't easy.

ptc62, Maybe if you had named your original post usefully, or had actually posted some test data yourself, I would have noticed it. Was I supposed to search for "million dollar question"? I understand your frustration as I HAVE kept up with the other threads and its a lot of work. But it's true I don't read the ones with ambiguous titles. As it is, your comment only disrupts an otherwise useful thread. Oh well. Sorry for any angst I have caused you.

Your "Million Dollar Question" topic tittle is very misleading. I wouldn't blame Vintage for not being able to find it and starting a new thread. You should have been more specific. "Today's update" can mean anything in the title.
Vintagephone, thank you for making a thread with a proper title. Thank you for your test results. Now I can stock you because I know your scooter route , lol jk. I use to live in Irvine, kinda close by. I'm glad the GPS looks like it's working kind of well in CA.

This is a useful thread. Don't worry. It's very specific to JH7 -and- GPS. Plus, the thread TITLE is perfect. Great post.
My test... using the GPS Test app, it took about 45sec to lock on the first try. After it locked, I rebooted the phone. The next time it locked, it took only about 15sec.
On a sidenote, I'm still having problems with the Use Wireless Networks triangulate my location. I have that checked and Use GPS unchecked. I had Google Maps (the latest version) try to use the wireless networks to get My Location but it says "Your current location is temporarily unavailable." Something is up.
On a much side(r) note, PC Connection (for tethering) is gone. Accessing GPS settings via phone dialer is gone. YouTube widget has rotating feature videos, and the screen brightness settings that used to be the dimmest possible became much dimmer.

I did a track using My Tracks for my ride home from work and it was pretty bad, actually. It was an 8 mile ride, and it completely lost my location (stopped recording on default settings) 3 times. There were times when it worked flawlessly, but other times when it just connected the dots taking me off the road... So far, I am not very impressed. However, it is functional enough to use location-based apps and do some navigation (but I wouldn't rely on it completely, you'll end up in a ditch).

Here's a track I recorded this afternoon. 7.52 mi, 31.62 mph average speed, 61.04 mph max speed. Blame afternoon traffic. There is one inexplicable gap, and one spot where the track veers off to the center of the freeway. The latter was while driving next to/under a raised expressway, so perhaps it's sort of excusable? I dunno.
Overall, though, the GPS worked GREAT on this drive. It's not perfect, but it's about 500 times better than it ever was before this patch. Previously, it would show me going completely off the road, and making loops at intersections. Not usable at all. But for now, I am tentatively impressed with this fix. Only time will tell if performance will degrade as in the past, but right now it's working so well it's astonishing.
The only distressing part is that the GPS got a 10 meter, 7 satellite lock on me... in the bathroom with no windows... on the... toilet.

OK, here are my real world GPS test results after installing the new update:
Just drove home from work, about 24 miles. I drive through residential, heavily wooded, congested business and open highway areas. The GPS locked on within seconds of me starting up Google Navigation. It was spot on for almost the whole trip. Only when I was stopped for a period of time (i.e. at a traffic light) would it cause a hiccup when locating me. For example, at one stop light, it located me about 30-50 yards to my right on the road perpendicular to me. But as soon as I started moving, it picked me up correctly. Overall, it appears that the GPS issues have been improved. Probably not completely fixed, but it was a good experience compared to before the update.

Thanks everyone with your test results! May I ask you to add where you had your GPS? Direct view of the sky? Through windshield? Hidden under under your dash? Locked in your trunk? ;-)

I was holding it for a little while, but then placed it in my cup holder by my shifter, then on the passenger seat. Either spot, it didn't lose its GPS lock.

Has anyone with the knowhow attempted to see what it is exactly that was changed?

It was sitting on the passenger seat during my drive. I don't have a car mount for it yet.

Tested mine today on my drive home after flashing JH7. It worked great (though mine worked decent on JF6). It found 8 satellites instantly after opening my gps test app, and locked on to 6 in under a minute. I drove home on the freeway for about 30 minutes with the phone in a car dock doodad and it never lost a single satellite lock.

I had flashed the vibrant files onto my captivate before and GPS worked amazing. I updated and yes it could find me indoors and outside, but the actual GPS lock was pretty much a street away from my actual location. It also lost lock multiple times. I am restoring my phone back to the way it was before the update. My GPS could get a lock indoors with no circle around me and it was 10x more accurate than it is after the update.

I tried to do the update earlier today, and it said it failed. I didn't think much of it. I went for a walk in the park later, and turned on My Tracks, thinking it would be a good 'control' to see how much better the new update would be once I got it working.
It took <10 seconds to lock, but I was outside in a park. After it got a lock, I hit record, put the phone in my pocket, and walked around the park.
http://maps.google.com/maps/ms?ie=U...68140665381380.000490e8a97287c8ebf1b&t=h&z=18
It's pretty much dead on, off by no more than a couple of meters anywhere.
When I got home, I checked back at the forums, where it was pointed out to me that for some people, the update claimed to fail, but actually updated. I checked my About screen, and sure enough, it updated.
So, while I don't recall it being particularly "bad" outside before, with the new update, it worked just fine in my pocket.

If your GPS seems fixed, please post your GPS settings. My update didn't complete successfully and GPS now is worse than before.

Here are some examples of errors from my track. It got me thinking: could the Body Glove case be getting in the way? I'll test it naked this afternoon.

This was a quick walk from my car to work this morning using My Tracks. It should show straight lines along the aisles but apparently the GPS still thinks I jump back and forth 30 feet at a time. The phone was in my front pants pocket, battery side out. JH7 was applied successfully yesterday. I'd say GPS isn't fixed.
I have to add I haven't had many problems with Runkeeper and GPS. The paths it records are almost perfect. Why My Tracks and most other GPS programs have such a big problem I have no idea.

Samsung says JH7 OTA does NOT include a GPS fix!

I just got off the phone with Samsung level 2 support, and she explained to me that:
1) The current AT&T JH7 OTA update does NOT include the GPS fix (as we've all realized)
2) The "real" GPS fix will be coming out BEFORE THE END OF THE MONTH (in the next few days)
3) This new OTA update will include JUST the GPS fix, nothing else.
I understand this is in contrast to Samsung's twitter account and facebook page that say the update is already available... I brought this up to the Samsung support lady, and she kept repeating that the "real" GPS fix is not available yet, it will contain ONLY the GPS fix, and it will be available as an OTA update before the end of the month.
She apologized for the confusion...
So should we get our hopes back up?
I hope so. Somebody on another forum was told the same thing so I really hope it's true.
Who knows what to believe anymore.
Well working for a large corporation I know that one hand has no clue what the other is doing.
My email to support got answered with the typical "we can't speculate when/if" answer.

The level-1 support guys were saying the update was already out with the GPS fix. They also told me to uncheck and re-check the "Use Wireless Networks" option. Basically, the level-1 support guys are clueless on the real issues, and they were likely the ones responding to your e-mail.
I'm going to wait until the end of this month... if Oct. 1st rolls around with no real GPS fix, then we know they are all full of sh*t
There is a definite difference in GPS performance on my phone since this update. It is not perfect by any stretch, but there is most definitely a difference in lock speed, number of satellites in use, and tracking.
Maybe this is not the fix, but they changed something. I don't know if it's at driver level or firmware level, but something is different.
Hopefully the rumors of a true GPS fix this month are true, but there is too much misinformation out there to even speculate as to what's accurate.

Yes, there are quite a few improvements over stock on this ROM. The compass is also much better, among a few other things.
However, the GPS is still too unreliable for Navigation, which the "real" GPS fix must still address. According to them, this real "fix" is still coming this month, and not here yet.
Dear Samsung:
Ass != Hole in the ground.
The GPS is definitely better. I saw the icon stop blinking and get a lock while standing still which I never saw before.
I call shenanigans on this. I just contacted Samsung live support and I'd post the conversation here but it was actually so useless that I'd just be wasting your time. She said she understands it's still a problem and to call so they can troubleshoot and that was it. I asked her to speculate on the source of the issue and got nothing.
GPS locks fast yes, but it loses lock just as fast too...
So the conclusion: No one really knows what is going on until I see a GPS OTA notification on my Captivate.
The Captivate is my first smartphone. My question is: has there ever been a situation where there is a glaring problem such as this GPS bug, where the manufacturer never ended up resolving the issue? What are the chances that Samsung sweeps this under the rug until it just goes away?

I don't know if I'm just an optimist but I don't think Samsung will leave this unresolved. The Galaxy S line is a world wide launch of smart phones and now a tab as well. They've invested too much into this to just leave it hanging. It seems pretty clear to me that they're trying to grab a huge market share and trying to be the next big thing in the smart phone/tab market.
So overall I have hope that it will be fixed. Whether it's a small update in the near future, or whether it is fully fixed when 2.2 is released, I believe it will happen eventually.
I would sassy this is true. I flashed my phone from the.zip this forum provided and my gps is no better no worse than before.. Hopefully in the next few days.

That would make sense, because I was able to get a quick GPS lock before and after the update, it just didn't track me very well before or after. Pretty sure any improvement can be chalked up to confirmation bias and wildly varying results depending on the test conditions.

There was a similar situation involving HTC and the Kaiser (aka ATT Tilt) about video drivers and it never got resolved officialy.
In stock form it would sometimes take 10 minutes to get a GPS lock in navigation, and on routes it would frequently lose my position, causing the nav program to reroute, and then reroute again when GPS locked again.
On JH7 (via Cognition) it took about 20 seconds to get a dead-on lock while standing in my front yard. I haven't used it in navigation yet, will do that tomorrow.
I've had two captivates prior to the OTA update, one of them was essentially non-functioning GPS, and the other was basically functional, but f-ed up. It remains that way today with no changes to the GPS settings.
The official release notes for JH7 didnt say one word about a GPS fix, and I can tell, my GPS is still broken. Thing is now, my compass is now broken. It at least used to point in the right direction but it would fluctuate within a 5-10 degree range. Now its 90 to 180 degrees completely off. I can look at maps and be driving down the road and the arrow is pointing behind me or somewhere perpendicular to my line of motion. What a crock. The only thing I noticed was an updated version of youtube, no more usb pc tethering, quick office is now included.
One positive is the battery life is longer. Where with the same usage all day at work I'm now at 60-70% and before the update I'd be at 30-40% by the time I left work.
I'm not looking forward to another OTA update, I couldnt get the last one to install, I had to use designgears' JH7-OTA.zip to get in installed, his zip worked great!
Edit: one note on GPS, the reported accuracy is much better, but its not true. Example, before it would say accuracy 100meters, and I might be within the blue 100 meter circle. Now it says Accuracy 10 meters and it reports my position as 100-200 meters from where I really am. So its not really more accurate, it just reports that it is. And it still fails to track me at all. Once I start moving (whether on foot or on bike or in car) it really gets whacky. Like I'm driving down the road and it starts to show me gradually leaving the road, by a block or so down the road I'm off in the middle of the block driving through people's houses or doing some serious offroading, when i'm still right in the middle of the road. Its tracking performance is abysmal.
And it seems that AT&T or Samsung took out the dial code to get to the lbstesemode menu. Dialing *#*#1472365#*#* now does nothing.

Wasn't that more of a poor performance due to lack of proper drivers, but it still functioned? All the HTC phones after that had the same deal. HTC didn't pay for the drivers from Qualcom. The phones still worked great. They just didn't perform, as far as video power, as well as the hardware was capable of.
I think this is a different matter. It's not the difference between running amazing 3D graphics and running pretty good 3D graphics. This is something that's plain broken. I can't imagine Samsung can afford to NOT fix this.
Now if the GPS universally worked "fine" at lets say with a 10 foot accuracy 99% of the time but the hardware was capable of being accurate to 10 inches 100% of the time then I could see Samsung possibly shrugging their shoulders. This clearly isn't the case though.

How confident are folks that we will get an actual FIX to the GPS issue?

Wanted to get a read from folks as to what their Gut feel is. Are you confident that Sammy will really fix this? Any by fix, I mean the following. This comes from experiences with 2 HTC smartphones (Aria, and the Pure):
1. GPS locks in under 5 seconds in clear sky conditions
2. Usable navigation; IOW, 30-50m accuracy, again under ideal conditions.
3. Usable navigation such that it stays locked while driving at highway speeds.
TIA.
I have not experienced any of the above issues (post update) except for the 5 second lock, and even my garmin can't do that. The cog2.2 had my gps jacked up so I reverted back and it works great again.
Sent from my SAMSUNG-SGH-I897 using XDA App
I did My Tracks for the first time today and was surprised by the results - highway for 15 miles, 15 miles off (obtained the lock at highway speeds as well) But it lost me in this one dead area about a mile from my house - I drop most calls through this one area as well too.. must be a whole in the ozone
However! (Always a however, right?) Tonight while walking the dog around the neighborhood, the phone could see up to 12 satellites.. yet it didn't get a lock for over 5 minutes. <--- This is the biggest problem I have with the GPS on this phone. INCONSISTENT AS HELL.
What causes the inconsistency?? So since I've owned the phone (release day) and it's been this long and inconsistent from the beginning, I am beginning to lose my confidence in a real fix (at least Samsung can make some kind of formal announcement you know?)
My GPS has always worked. Stock JF6. Cognition 2, 2.1, 2.2.1-5. Anything I throw at it, it just works. Freeway, walking, indoors, etc. I think it is partly a hardware issue.
Mine is fixed
I ordered my Captivate from AT&T's online store. GPS did not work, no matter what kind of settings I played with (lbstestmode, etc.). Got the update, no help. Took it back to the AT&T store and replaced it. Got the update and it works fantastically. If yours is still in the 30 day warranty period get it switched out.
Considering that many people had the gps issue fixed with the ota update or with the newly released froyo, yet many still have problems, I think there are some bad phones. I'll try to get mine replaced even though it's outside the 30 days.
Sent from my SAMSUNG-SGH-I897 using XDA App
I'm on my second Captivate. I have no faith that GPS will be reliable enough to use for navigation purposes or apps like My Tracks or even Layar. The OTA update definitely helped, but turns and changes in direction throw it off by quite a bit.
About all it is good for is telling your weather app what city you are in.
For me, the GPS didn't work from the first day I bought the phone. It got a lot better after the OTA update. However, it's getting mess up again in the last few days. I've heard other people from this forum said the GPS will go bad after a few weeks, I guess that's happening to me now. Moreover, the lag seems to be getting worse too.
I'm running Cognition 2.2 FroYo and for the first time ever I got 11/11 sattelites locked. My ride home it stayed more or less dead on the street i was on, occassionally wavered onto the sidewalk a bit or whatnot in My Tracks. That's using the stock settings (spirent-lcs.com and Standalone, with Use Wireless Networks off). If this does not degrade over time, I'd call it fixed for sure.

Keep it coming folks; seems like for the most part people's gut feel is about in line with mine. Im going to return my Captivate to Amazon and have them replace it to see if I can see any improvement. Not holding my breath though.

Mine has always worked on both of captivates. It's in no way perfect but it gets the job done.
I just ordered a replacement Captivate from Amazon. I will then update the software to JH7 in the un-mollested state to see what kind of improvements I see, if any.
Crossed fingers............Bottom line, im not too confident.
So I got my replacement Captivate from Amazon. The second I got it, I stepped outside to see if I can get a GPS lock. I stood there for 5 minute, and no lock.
So I did the software update; which worked. It didnt work on my "molested" captivate.
I then went outside for a drive. Locked very quickly I think 5 seconds. Accuracy was very good; certainly on par with the two HTC smart phones Ive owned.
Maybe its dumb luck that I got a good unit; but it seems not overly molesting your captivate is a good idea until people really understand the consequences.
EDIT: The above drive I mentioned was in neighborhood roads, at relatively low speeds. On my way to work it was definitely NOT as accurate as my HTC Pure. It showed me about 1 exit behind; was about a half or three quarters of a mile.
I just want to say that I called Samsung support directly yesterday and the guy told me that "he hasn't heard anyone else who's applied the JH7 update that said their GPS wasn't fixed."
SO CALL SAMSUNG SUPPORT FOR THE LOVE OF GOD. Don't stop calling. They need to know the update didn't fix it!

They already know. I can guarantee you that some of their dev team consistently troll these forums.
My GPS works pretty well, especially considering its a phone, since JH7 OTA update.
The problem you're talking about with locks under 5 seconds, isnt always going to happen. It depends on how long its been since the last time gps was used, and how close you are currently to where you last used it.
If you use it and then turn it off, and in a few hours turn it back on, at roughly the last location it was used, it'll get a very quick lock. If you wait days, it wont. If you use it at location A last, then are long ways away from that location when turning it back on, it wont get a quick lock, it has to calculate where its at based on new data from the satellites. Thats the nature of the beast with GPS. My Garmin in my car is the exact same way. If it has to do a cold start it sometimes takes up to 2 mins to get a lock. But once its got it, if I go in a store for a few mins and come right back out, it picks up location almost immediately.
Since JH7 I'd say my GPS performance more than meets my expectations for a mobile phone GPS.

Yeah, I'm with you here.
When it came to the HTC video driver fiasco on many of their phones it was sickening that HTC wouldn't do anything about it, or even tackle the issue on future releases. But at least slower video performance than the hardware was capable of wasn't really a deal breaker when it was still working good. So I could understand why a company wouldn't invest a ton to fix it for already purchased phones.
This however is outright broken. It's not a phone with good video performance that COULD perform better with an update. It's a phone with a broken technology that can hopefully be FIXED with an update.
I don't know how Samsung will avoid lawsuits etc etc by manufacturing a blatantly broken piece of technology unless they can rectify the situation... quickly. I think their window is slowly closing on this type of scenario.
As for myself, the GPS problem just isn't an issue since I don't use the GPS anyhow. So I'm not a consumer frothing at the mouth, but the idea that I spent money on a fancy, but broken, phone leaves a bitter taste in that unfrothy mouth of mine.
I'm very confident. I put the leaked froyo from designgears on one of my phones and the lock was fast, and gps accurate. Drove from Chicago to Kohler, WI the other day (~130 miles) and ran gps on the phone along with my dedicated gps unit to check accuracy. Had no issues at all.
I think once 2.2 is released, all of the gps issues will be resolved if the leaked version is any indication.
I'm guessing it's the sum of several issues causing problems.
1. Basic hardware configuration that results in worse signal-to-noise than other handsets.
2. Non-optimized settings that sporadically contribute to slow or poor locks
3. Some kind of software buffering or other issues that cause freeze-ups where the position doesn't update.
When my phone is working well I don't experience problems 2 and 3, and I can live with problem 1. When that's the case I get consistent tracking 95% of my trip. Sometime 2 and 3 seem to creep into the picture for no apparent reason. I hope and expect they will get those problems solved.

Gps broken forever? Hardware or software.

I really need to know because I drive an ambulance for a living is the GPS actually fixable? I love the phone but hate the GPS that locks up and is inaccurate, or just doesnt lock on.The tweaks I've tired. No luck. I called Samsung and asked and they have no clue and think the Sept patch worked. I think its a cover up and the first run is just plain defective. What's the probability its hardware and not fixable.
Thanks Travis
Call att and get it replaced. I got a replacement phone and so far the GPS has worked when I needed it. It locks pretty quickly most of the time. Sometimes it takes 20 to 30 seconds but always locks reguardless

I'm pretty certain it is a hardware problem and Samsung is trying very hard to see if they can fix it, or 'optimize' it, in software to avoid a mass recall of millions of these phones.
Smallsmx - a quick lock is very different from reliable navigation. Driving around using Google Nav as well as analyzing using something like MyTracks is the way to go to see if the GPS is actually accurate.
Here's a track I just created with MyTracks. If you zoom in, you can see that the track jumps between the north-bound & south-bound lanes of the highway several times, as well as veers off of the road several times. These may seem insignificant, but they're the kind of things that play havoc with navigation software (constant re-routing, etc). Also note that I'm in a rural area; i.e. no interference from tall buildings to blame this on...
I'm pretty convinced it is a hardware problem.. I've been through 4 Captivates, and only 1 has worked. The Captivate that has the working GPS works on all ROMs, but works best after JH7 (or the froyo builds). The other 3 Captivates, the GPS doesn't work anywhere.
I wouldn't want to trust my life to the Captivate's GPS navigation! If I found out my ambulance was being navigated by a Captivate, I'd wait for the next one

Please don't use the C(r)appy GPS for anything like that! It's just not up to it! Even if the GPS does work from time to time, you'll spend too much time second guessing it. Get a dedicated GPS that you KNOW works so you can concentrate on doing the important stuff like not hitting other cars and saving lives!

I'm pretty certain it is a hardware problem and Samsung is trying very hard to see if they can fix it, or 'optimize' it, in software to avoid a mass recall of millions of these phones.

Agreed 100%. If it was a simple software bug, it would have been fixed in JH7. They initially claimed JH7 fixed it... And then they contradicted themselves and said there was no GPS fix in JH7.
So Sammy is confusing us with smoke and mirrors and hoping they can still circumvent what is likely to be a recall only fix. Imagine the impact of a recall. Cost would be huge. PR would be a nightmare. Impact on future Galaxy S sales would be massive. See how cleverly and deviously Apple avoided an iPhone 4 recall with what was clearly a major hardware defect.
And for those of you that say your Cappy's GPS works perfectly, there is one of two conditions that apply:
1. You got a lock while stationary from > x satellites and assume from that alone that GPS works. A better criteria would be GPS tracking while driving in an urban environment with accuracy < 5m.
OR
2. The hardware defect is an intermittent assembly or fabrication issue that shows up in the majority but not all handsets.
So here's to hoping I am wrong and the official Froyo build is being held up while they correct the GPS problem once and for all. If not, here's to class action. In the meantime, Sammy and AT&T product managers, if you are reading this (doubtful) give us the source for 2.2 (kernel, hardware drivers and all) and let the XDA community have a crack at fixing it (and enable HSUPA, FM radio, native etx4, etc while their at it).
Before i flashed to the JPM and the reorinted 2.1 my gps would not get a lock after 10 mins after I flashed to the i9000 rom and shanged the gps settings to ms based I get a lock after 15-25 sec at 15m. its software related and att's reps are just dumb as dog **** and full of it too

No need. We have millions of threads for just that. We need the evidence that you actually use it for navigation while driving. That's where it all falls apart (for majority of the Captivate anyway).
I can get a lock no problem as well with no tweeks in settings. But that doesn't mean the GPS is anywhere near usable.

Misread the forum. I have not used it for a gps on the road for navigation yet.
I have watched it on the way home from work and it was prittyy accurate.
funny thing.
I dont get a lock from my cup holder but i get a lock no problem and the gps works on the dash board.

if it is any differance all the sgs varriants are having a bunch of gps issues.
and there are people that have had no problems.

I'm sure the loss of future sales will cost Samsung more than a recall. My last 3 phones were Samsung and I sure as hell know if they don't fix the GPS issue, whether it be through firmware or a recall, Samsung will never see another dime from me ever again and I'm sure there's plenty of others feeling the same way.
There would probably also be about no PR. Samsung is no Apple. The media and general public really don't give a damn about them. The issue is not so controversial that the news will pick up on it, like the Toyota recalls. At most there would be a couple sentences on the news about it that most people will just ignore because they don't have the phone. Apple got worse PR by ignoring the issue than if they simply would have addressed it with a recall. They got away with it because they're Apple. 90% of the population worships them.
I was just thinking the same thing. My GPS does not work.
I don't understand people who think it's no big deal. It's a major feature and an Advertised feature...not some hack.
I would not have bought the device without GPS. What if you bought a new car that said it had air conditioning...but after you bought it...you realized it didn't work....no big deal or recall?
CLASS ACTION LAWSUIT!

yea its a cover up
My whole plan and philosophy was that hey Google maps is great and so is Linux so this should, be better than those goofy slow interfaced GPS units.... which always give you the wrong location....
Anyhow I ordered one more..to see if its a dud too.
1ST SAMSUNG AND MY LAST YOU HEAR THAT SAMSUNK.. BTW your customer service is so poor girl who knows nothing about phones and thought the update was "real".
Jupiter fix w/vibrant ROM. Seems like I tried everything. Plenty of sats and locks while stationary. Can't get this thing to maintain lock or be accurate while moving in navigation for the life of me.

I'm hoping for a software fix, but I'm doubtful that we'll ever see one. This is the same GPS chip as used in at least one blackberry where it has no problem. Combine that with the fact that there's 5 different Galaxy S phones that have these issues, each with slightly different layouts of where the chips are on the board, it's more likely a software issue.
If it is a hardware issue, or if it's a software issue that they never get around to fixing, I could see a very nasty class action lawsuit pop up. Personally, I hate class action lawsuits, as the only people who usually benefit from them are the lawyers, but one can always hope for the best.
One interesting thing I did notice was that when in my vehicle (a Jeep Wrangler with a fiberglass hardtop) or on my motorcycle, the tracks are just about spot on... as long as there aren't any tall buildings right next to me. It stops when I stop, it turns when I turn... You know, pretty much what you expect out of a GPS.
On the other hand, when I'm in a friends vehicle (metal roof, no sunroof), my position wanders all over the place. We stop, but the icon keeps on going. We turn, it doesn't. And, of course, there's always fun times when it thinks your a block or two over from where you are. Oh, and can't forget the lag... sometimes it's as much as 5 seconds behind me.
That makes me suspect the filters Samsung has in place for when the signal is weak. Either that, or the antenna design they use might win the distinction of being the most craptastic one of the decade. Hell, maybe both might be the case.
This whole thing with the GPS has me baffled..after reading a bunch of threads...posts..and personal experience, I believe the problem with the Captivate's GPS is the delay in getting a lock. Once it's locked, the accuracy is excellent. Maybe the agps is not functioning properly...these devices really need agps to get a rapid lock. Is the supl server that is built into the device reliable? I believe this is the crux. Anybody having any inaccuracies is the exception to the rule once the device is locked. But a 3-4 minute lock time is fairly unacceptable
Same results as others. If I have the captivate high up in the windshield so it has a larger uninterrupted view of the sky, it will track almost as well as my Blackberry sitting on the center console. Seems the captivate is not nearly as sensitive as other GPS devices.
As for PR, a recall would not be in your nightly news but it would be all over the trade news. The Galaxy S brand has been in the trade news almost daily for the past few months. A recall would put a serious dent in all that positive momentum. That would have a serious effect on future deals with carriers, retailers, etc. Not to mention investors. And finally disaffected consumers.

Questions for ya if ya don't mind.
1. Did you have problems before with same phone?
2. Phone new or refurbished?
3. When was it made give or take? (maybe import in terms of factory runs???)
Hmm thats it far as identifying maybe some know how to timestamp/get ingo from imei or serial.
I'll post a track from mine in a little bit I Think that would be a great idea for this thread.. POST YOUR TRACKS RESULTS AND BASIC SPECS.

CORRECT Hardware GPS Fix - For Captivate?

Hey guys,
Wanted to know if anyone has tried this:
http://forum.xda-developers.com/showthread.php?t=878970
I was trying to do the same thing on the Captivate realizing that the connector is readily accessible just by opening the battery door. Mine is a 1008 (number below S/N) telling its an August 2010 build so I tried. I am not sure about the results (improvements) and this may be because I am missing something. Want to know if anyone who has 1010 or earlier tried this successfully?!
Also, if that is a true fix which we are hoping, then does that mean the GPS antennae is on the battery door? Is that solid chip looking thing pasted a gps receiver? Experts please comment. And if that is a real antennae on the door, then without the battery cover the GPS should not work at all (with network thing off), but mine did. And if that is NOT the antennae, is it below the screwed down panel below the battery (like the vibrant)?
Just trying help myself and possibly others. Maybe I am going in completely wrong path, but it never hurts trying .
Feedback and comments please.
Thanks!
This would be awesome if it worked but I wanna make one comment. My GPS before the latest Dary 7 roms (The Darky 7/7.5/7.6 and now 7.7 ROMs) has been complete and utter crap. It never could maintain a lock if it ever got one in the first place, but now it is WAY better and even gets a lock when I'm under cover sometimes. Even when I'm driving it is totally usable and feels almost as good as my Nexus One did. I know my phone was manufactured before oct, but try out one of those ROMs before you go modifying your phone physically.
A thread for this fix is located here.
http://forum.xda-developers.com/showthread.php?t=876179
I have done both, bending the contact up a bit and scraping the film of the other contact off. It definately made an improvement. Now, will that improvement sustain throughout ROM's is a different story. But I definately got locks in 2 different places within 30 seconds. Very accurate locks I might add.
I think that the GPS problem is a hardware issue and not software. Sure, software can make it a little better. I had to replace my phone due to shutdown problem and the GPS on the new phone is absolutely perfect, no matter what ROM I use. That's my 2 cents though.

just wanted to add this to the GPS saga-
my Father In-law has the Sprint Intercept - this just got the 2.2.1 update - I know this is a different phone than the Captivate and the hardware is probably not laid out the same, but I wanted to compare GPS side by side.. before the 2.2.1 update the phone took FOREVER to get a lock and accurate reading.
So his Intercept in my right hand, and my Captivate with JPY ROM (and with the Google GPS files floating around here as well) in the left hand.
Tapped on Google Maps at the same time, and the Intercept phone got to 2meter Accuracy before the Captivate got to 10M accuracy.
This has already been covered 3 or 4 times on this forum. search before posting please.
You guys should try Doc's 6.2.1 Rom. I am getting instant gps lock and it follows quite well.

A working way to get a GPS lock

Well... As we all know, gps is **** on our captivates. That being said, i found a way to get a gps lock, and almost all the time..
However the method isnt as simple as opening up Gmaps and pressing my location.
I have only tried this with Apex 8.2
To do this.. you have to enter AngryGPS (*#3214789650#*)
Then go to tracking test... Wait for it to present values of your latitude and longitude.
Once these values are there... press maps, and voila
Uhhh seems like the code is for lbstest. Well if so... By using a test feature all you are really doing is turning your gps on(all the time). Which will basically always give you quick lock because the gps is always on unless you kill all your apps or re-open lbstest and back out. Not really a fix, more of a drain on your battery. Only true fix for older models of this phone is to get a refurb'd from atnt/rogers in your case. (not samsung).
Once opened, Angry gps looks just like lbstest. For some reason it was renamed.
Just need to figure out a way to do this with Tasker.
Ah, in that case.. cant you just program tasker to only turn gps on when you open maps or a navigation app?

Yeah, but how do you program tasker to open up lbstestmode... then run the tracking test... wait about 10 seconds... then open up maps?
So let me see if I get this straight. You start GPS, wait till it gets a lock and then open maps and you have a lock?
that's what we used to do on Eclair.
NascarFastcar is right, the only real way to have a working GPS is to get a refurbished unit. Most of us early adopters are going past our 1 year mark, so if you haven't, get one quick!
I still have a couple months in my warranty left. What problem would I go to them with?
The GPS is fixed on a refurb?

Tell them the gps dosent work. That's all. They will most likely try to get a lock indoors lol and then they will just give you a refurbed. They like to use google maps. I tried to show them gps test etc and they tried to blame my gps not working via a 3rd party app.

Well since april 2011. All refurbs seem to have been fixed. Still have to watch out for older modeled refurbs that still might have random shutdowns. I know had about 6 refurbs with shutdowns after a week or two. But they all had great gps.

I disagree that the gps is fixed. I just got a refurb about 6 weeks ago. The gps worked awesome for a few weeks. It now sucks eggs - actually worse than my last phone. Totally stock, just like my previous phone. I don't know the build number because it has a weird refurb sticker that doesn't have a build number on it.

Take it back and get another one until they give you one that works.

I've learned how to use it. I know others have tried, but here are the ONLY real instructions that work:
1) You have to always look 2 steps ahead of what it says when using Google Maps on a Captivate because you never know when all of a sudden it will think you're on a different street and start giving you directions on how to get back on the correct path.
2) When she it starts telling you how to correct yourself (when you're actually already on the right path) learn how to IGNORE it or it will confuse you
3) It's ok for occasional use, but always and I mean ALWAYS have a real GPS handy in the glove compartment for the occasions when your Captivate decides that it isn't in the mood to lock onto any statellites even when it sees 7 or 8 with a with strong signals
4) Always have a real GPS handy when your Captivate can't locate ANY satellites.
5) When in Maine or rural New Hampshire don't even think about using your Captivate!!!
6) Overlook it's GPS defects because it's so awesome in every other way.
Does this post earn a sticky? We should coin a pharse that encompasses all of the above (you know your Captivate has trained you in a similar manor).

Ah but you see, i dont drive. Well i do... but i dont have a car. So public transport is what i use and luckily, google maps supports it. Basically all i need is a position lock, rather than finding my house, tracking down whatever streets i used to get to wherever i am, then selecting that as a point...
I returned my 1008 Captivate because of random shutdowns last week and received a 1007 refurb and the GPS was perfect on 2.2.1 and continues to be perfect on Apex 8.2. Also, no random shutdowns.
Exchanged a 1007 Captivate in My, got a 1010 refurb. GPS is about 98% as good as my Garmin GPS in one car. In the other, there must be some kind of interference scit doesn't keep a good signal in the location I put it navigate.
I find it fun to see the difference in the routes they provide.
The 1010 model can also track me walking on the sidewalk. I was watching Google Earth zoomed in as far as it would go.
+1 on returning the phone to an AT&T device service center. I went several weeks back and tested my phone when I got home and it was worse. Went back the next day, the girl there first turned on the "use mobile network" option and told me the gps was now working. I got a little aggrevated but politely pressed on, she then told me the samsung captivate has no gps in it, this sparked my asshole lawyer mode. After making the girl feel embarrased in front of her coworkers for insulting my intelligence I demanded a different rep work with me. I had him go thru 7 phones before getting one that had a working gps. After the 2nd, they told me I would have to call customer service, I laughed and told them that this is a customer service center and my contract entitles me to burn through every single unit they have until they fix my device issue. After the 6th the guy finally paid attention to what I was telling them about looking at the build number (because they have to send all those phones back to samsung). I now have an 1101 that has been working great for about a month. If it screws up again I will go ruin their day again.
