This might be my first post ever, however, long time lurker on the boards.
I think I have a potential fix for the GPS issue with the Captivate. I don’t think this is the same as the “quick fix” found elsewhere on these and other the boards. I am not sure what (if any) 'side effects' there are to this.
My phone previously had the AT&T/Samsung fix from late September applied, although it didn’t seem to help.
Get to the Lbs test menu; previous available through *#*#1472365#*#*. However, if you previously installed the recent AT&T/Samsung (supposed fix) for the Captivate, you can’t get to the menu through the dialer. Use Anycut from market to get to the Lbs test screen.
My GPS now gets a great lock about 30 seconds.
BTW, I am not root….
YMMV. You should record your original settings prior to making these changes, just in case you need to revert.
Standard Disclaimer; I am not at fault for any issues this causes your device…..
Now, down to the settings that I use:
In Lbs test menu:
I “deleted GPS data”
Application Settings
– Session Type: Tracking
– Test Mode : S/W Test
– Operation Mode: MS Based
– Start Mode: Cold Start
– GPS Plus: Off
– Dynamic Accuracy: On
– Accuracy: 50
– Use Skyhook: Off
– Use PC Tool: Off
SUPL/CP Settings
- Server FQDN Type: Auto Config
- Server [leave what is autopulated]
- Server Port [leave was is autopopulated]
- Supl Secure Socket: On
- AGPS Mode: SUPL
Reboot.
Use GPS Test from Market, or the The “Get Position Test” menu from Lbs screen to validate.
WIFI Problem:
One thing I have noticed is that depending on the settings above, wifi (if on) sometimes inhibits the ability to see more than 1 satellite. I think the problems with GPS are overall related to Wifi in some way.
If you do not have luck with above settings, turn wifi off and see what happens.
I only had to change a couple of the settings but this is working nicely so far...Ill try again over the next day or so in various situations and report back.
Changed:
Op Mode to MS Based
Start Mode to Cold
Turned off GPS Plus
Secure Socket to off
Thanks!
I'll admit some of this seems counter-intuitive, but at this point anything is worth a shot.I'll let you know how it goes!

You don't need to download anything to access the Lbs test. Just type *#*#3214789650#*#* in the dialer and you will get access. Works with JH7 and Froyo.
Before anyone else reads this and declares their GPS fixed, they should read at least the first post of this thread completely. http://forum.xda-developers.com/showthread.php?t=789383 If you understand what is being said by that post, then you can offer GPS solutions. The only thing you have changed is AGPS settings. While those settings will get you a lock, they don't help out with accuracy. If you really want to test your GPS, you have to turn off the use wireless networks feature, take it outside and see how well it works then.

Nope, it's definitely not fixed...but it did give me a better lock than before. Same old...

Well if its not a fix then it is most definitely better...I can get a lock in ~20 seconds where as before it might not even come close.

Additionally, a lock is not enough to say it works. Take it for a drive along with another GPS device - use Google my tracks or some other tool to record your path. Even use GPS test and watch your MPH, direction and location.
You will find that it is not fixed. It works OK sometimes, but many times it is behind or inaccurate.

You will have to do that every week as your cached GPS data expires. And you can literally use any settings as long as you can use the lbstestmode to accquire a lock. That's all you need to do (accquire your first lock and it will cache the data for 5 to 7 days).
Any "fix" that involves "settings" isn't a "fix" at all since it demonstrates an utter lack of what the real problem is and how GPS fundamentally works.
The real "fix" won't come in the form of settings. Any purported settings "fix" is snake oil.
I've given up on GPS a while ago.
It's a fringe feature anyway.
I never have "use wireless networks on" and gps works good enough. It may not be perfect but everytime ive used it it has got me where i need to go no problems. It may jump off track or be slow to turn for a second but it still gets me to wherever just fine.

If I read this correctly your turning off skyhook ? I read this http://www.skyhookwireless.com/howitworks/, and to me you need it turned on for urban areas and in the city need wi-fi turned on because of the occlusions caused by buildings and such...?

That option has nothing to do with GPS. 'Use Wireless Networks' is actually quite useful for location aware apps like Google Maps, Places, Speed Test etc. where an accurate but slow GPS lock may not be needed (or even possible if you're underground or inside a concrete building). This option enables those apps to use cell tower or wi-fi signal trianglation to get a quick estimation of your current location so that apps can give you relavent information, i.e. nearby gas stations or resaurants. It has nothing to do with aGPS either.

You have to be kidding saying its a feature right? I can't believe how many say that its a feature and that it is ok that Samsung is screwing them ( along with placebo updates) . I myself love and would like a Galaxy S phone or even the new Focus 7, but its looking like it too has GPS issues from early reports with the Omnia 7.
I know most of you guys are already locked in with your carrier and don't have much choice with the GPS issue but its not a feature, its a valuable function just like placing calls, sending emails, texting, etc.. If you don't care about this, then you should of bought a Razor flip phone.
I have been keeping up with this because I really want to see Samsung resolve this and make right.

My reasons for a working GPS are as follows:
Pinpoint your location, get turn-by-turn directions to restaurants, businesses and other destinations, location-based mobile games, social networking sites, real-time position tracking, lost or stolen phone tracking, etc., etc., etc..
What I am saying is just quit making excuses for Samsung and demand what you paid for! There are people on here who would really like for their GPS to be working and rightfully so.
Oh, I agree that it should work as advertised. Can't say Samsung is ' screwing' me because they can't get it right. Would have bought the phone if I knew about it beforehand anyway. There are many other features that led me to the Cappy. Samsung does need to fix the problem and I hope they do so soon. Buy I won't try discourage anyone from Samsung products in the meanwhile.

The solution to the GPS problem is quite simple, but most people still don't see it.
If 100% accuracy and < 10 second fixes are more important to you than the rest of the Galaxy S features, then you do not want a Galaxy S phone. Either return the one you have or don't buy it. For most people, that good of a GPS is a bonus and not a requirement.
The GPS problems are not undocumented, anyone reading any reviews for the phone will realize that the GPS is not as good as other devices. Even if they don't realize it before they buy it, they have 30 days to return it. Samsung may or may not ever get the problem worked out since phones have such a short life cycle. *****ing about it in thread after thread, online petitions, and idle threats of legal action will have absolutely no impact on Samsung.
How to fix the gps on the Samsung captivates GPS.
Insted of MS Based use MS assissted
Lbstestmode -> application settings -> operation mode-> MS Assisted
Let me know how it gose

*facepalm*
This does nothing. It makes it marginally better at best (read: not better at all). If you're really having that much trouble, flash to KB1 and use the PlumbBob GPS fix. Those ACTUALLY do something.
For most your suggestion will give them the most lag and least accurate GPS positioning.
I suggest you in stall Adams GPS fix to your phone, that or use ga_D's. (gadnarf_gpstweak_att)
Both are much better than what Samsung has provided...
There is also plumbBob GPS fix, but when I tried his version 2nd Beta 6, my GPS only saw 2 sats with no locks even with 10+ minutes of waiting... I did not try version 1 of his fix.
As for the GPS settings, use either Standalone or MS Based(some drift with this setting, much less than ms assisted) . Set your support server to google, distance to 80 and good luck...

MS Assisted = uses cell towers only to determine position. Intended to be used for 'dumb phones' that are not GPS equipped or where only 'coarse' location data is required.
MS Based = uses cell towers to provide approximate location for initial fix, then GPS thereafter.
Thing of it is, Samsung's configuration interface for the GPS is so silly that changes in LbsTestMode don't always really affect anything. If you're getting good results after applying this 'fix' it's just coincidental, or perhaps that you'd finally used GPS long enough to get almanac and ephemerides downloaded over the satellite signal and your GPS was able to function unassisted.
What about this has anything to do with development?

I decided to make this a separate post...
My original phone had all sorts of trouble - GPS was the worst. I don't know what my original one was, I do recall I'd applied the OTA update that was supposed to fix the GPS issue - it didn't.
So I got a warranty replacement phone - it worked fine out of the box, but the next day it was doing the same old crap.
This one came with the OTA update pre-installed. It's a "1010 rev. 0.4" if I'm reading the sticker under the battery correctly...
I read countless pages of stuff online, tried various "fixes" that were posted, all with similar results.
One discussion I read was posted by a guy who claimed some GPS expertise, and indicated that the problem was in the driver - to paraphrase from memory it was something like the cache was getting corrupted and the HW/driver wasn't cleaning it up.
He basically said that they needed to write a new driver, but until hen you could use a 3rd-party app to clear the cache and re-download clean data from the satellites.
I found a (FREE!) app called "GPS Status & Toolbox" by author "EclipSim" (Disclosure: I have NO CONNECTION to this guy, just like his app!)
It has 2 menu options:
"Tools -->Manage A-GPS State-->Reset" and
"Tools -->Manage A-GPS State-->Download"
After doing those, it will usually grab a fix within 15 seconds at most. Once it's "timestamp" is updating every second (you'll see, in the app) I can then switch to Google Maps and it too will get a fix before too long.
Another nice thing about the GPS Status app is that it shows you how many satellites you "see" vs how many you're connected to. When it only sees one or 2, or when it sees a bunch but isn't connecting, you can be sure you need to reset/download again...
This thing DOES eat battery - so it's a good idea to be plugged in, or to kill the app once you've got Maps working the way you need it to...
Yes - it's a PITA to have to do all this to get a basic function of this high-dollar phone to frigging work - but it beats having it NOT work...
Hope this helps someone!

Plumbob didnt do much for me. I am pretty well convinced that with the utmost optimization, the crappy hardware in the captivate can operate marginally well at best.
Ryans Plumbob fix does work. Its a much better improvement over stock on defected models. I had a 1009 and it worked great but the tracking and navigation were still buggy unless the phone was placed on the dashboard. (Always had a larger blue circle and would skip at times).
Finally gave up and noticed that the local atnt is a device service center. Went in and got a refurbed 1008 with stock 2.2 and the navigation is excellent. Even sitting in my lap...
I mean you all should still have the 1 year warranty. Just find a service center and exchange your phone. Hell the refurbed one I got was in better cosmic condition then my original.

i know everyone will tell me im wrong but try running the samsung gps restore app once then remove it from your phone. it is free in the market. and i assure you t doesn't revert to stock settings. atleast not in any location that i am aware of. i have checked the jupiter .xml and secgps.conf and lbs test mode before and after running the app and it doesn't revert anything. but it does seem to clear errors that may be caused by messing with settings without haveing a proper jupiter.xml or config file first. for instance on old roms if i chose msbased mode in lbs test mode it would work for 6 minutes and turn off. even after reverting the settings and clearing gps data the gps would turn off after 6 minutes. running gps restore or doing a factory reset were the only two things that would make my gps work again.
also yes google maps and captivates dont agree with each other 100% of the time. it is thought by some that the gps is recieving interference from the cell antenna (that's one theory at least) so the more data you use as you navigate the more issues you might see if that is true. try a gps app that downloads the maps to the phone. it takes up alot of space but if the app agrees with the phone it is worth it. in the past i had trouble with some aftermarket apps as well while others swore the same apps had solved there navigation problems, so try a few and find one that works. navdroyd is great on my phone.
also, though people are raving about plumb bob's fix, i have more blue circles with it. the problem is the msbased mode. it doesn't work on my phone very well. (back to the data/interference theory) i instead use Da_g's fix the control plane version with lbs test mode supl settings set to control plane and i turn off dynamic accuracy. and i use the kc1 modem. there are other modems with good gps but kc1 has the best call quality of them.
I've owned a GSM Galaxy Nexus (Samsung i9250) with JB 4.2.1.
The one deficiency that I didn't initially notice is the lack of decent GPS reception.
My friend have a galaxy S3 take 30seconds or less for fix gps without wifi ou 3g. The nexus make maybe 10min GPS lock on its own (no Wi-Fi required) and then would keep the lock the whole time when the phone was in my pocket.
The GPS of nexus is, quite simply, broken. It takes, on average, 5-10 minutes to get a GPS lock when standing outside with a clear view of the sky and the phone in the palm of my hand. Sometimes it takes longer but usually I give up after 10 minutes because, strangely enough, I do have a life. Unfortunately, even after this GPS lock is achieved, it loses it easily. Putting the phone in my pocket will cause the GPS lock to be lost within a few minutes, typically.
Unfortunately, it appears that I'm not the only one with the problem. This is unfortunate because this means if I call Samsung asking for a replacement phone most likely my situation will not improve.
Strangely enough, if I enable Wi-Fi and are within the vicinity of some networks, I can get a GPS lock fairly quickly. In fact, even sitting here in my condo typing this, with Wi-Fi enabled I can get a lock within a few seconds by holding the phone near the window. The phone will only see 4-5 satellites, but that's all that is needed for a 3D lock. This makes a little bit of sense because WPS probably seeds the GPS subsystem with location data so it knows exactly where to start (vs. a cold or warm start).
After searching around a little bit I found a few suggestions. One was to shut off the phone and remove the battery for a few minutes, which seemed silly since this suggestion only temporarily fixes the problem. The second, that seemed to work for a few people, was to force a cold start and redownload A-GPS data, both of which can be done using GPS Status & Toolbox, an application I've used in the past and is pretty darn neat.
Unfortunately, performing the cold start (reset) and redownloading the A-GPS data didn't work out for me. I was still left in the same situation as I was before. However, using the GPS Status & Toolbox provided me with some additional information about the GPS problems. Apparently when the Galaxy Nexus is stuck searching for a GPS lock, usually it actually does see a whole boatload of satellites, but fails to receive any data from them.
GPS lock with Wi-Fi enabled. I don't even have a clear view of the sky since I'm indoors. However, I'm standing at a window:
Why does the GPS on the Galaxy Nexus not quickly receive the second and third parts of the GPS message from any satellites when Wi-Fi is disabled? According to the first screenshot above, it can clearly be seen that a number of satellites are providing adequate signal strength, but most are just stuck in the no info stage or have only processed the first GPS message. I wish I had an answer.
I suspect the problem may be due to inadequate RF shielding of the GPS receiver inside the hardware itself. Perhaps the GPS receiver is getting a strong signal but it's too noisy and the messages are chock full of errors and can't be processed correctly. This is really only speculation, though
I tried so many things, gps.conf etc..maybe is a hardware problem ? isnt the google location server problem..
Anyone have any suggestions or comments?

Hoobinho,
I'm having the same problem.
I'm pretty sure it's software related, because 4.1.2 worked very nice with GPS. This issue started after 4.2, and continues with 4.2.1. I will roll back to 4.1.2 as soon as I have time to do it, and stay there until Google fixes it.
Hello community,
thanks in advance, I have used this site as a knowledge base many times in the past and always found something helpful. Now, however, I will have to ask since I don't now what to do anymore.
I run an i9195 (serranoltexxx) with cm13 and gapps installed. Everything worked just fine. Then I dropped my phone into a bucket of water/household cleaning agent, took out the battery immediately and dried the phone. When I took out the battery, the inside of the device was still dry. After that, I could not use the earpiece for a few days, but this issue has healed itself. Also after this incident happened, my gps was still working.
Now, all of a sudden, gps does not work anymore. I have tried google maps naviation app, gps test and gps status to check, no satellites are found. When using google maps and driving around, the device keeps the rough location, I assume by using the other sources like wifi networks or broadcast cells. Hence I do not think that the location service is entirely faulty.
Now, do you think this is a software or a hardware problem? How can I find out wether or not the gps antenna is broken and needs to be changed? Please be a bit gentle with your answers, I do use a custom rom but would not describe myself as an experienced user
Is anyone experiencing problem with their GPS signal? Mine would lose the GPS lock constantly. Thanks.
Working fine on my end. Out and back, my drive was 5 hours total.

Do you have a case on your phone?
I just got my cases in and have noticed weaker gps performance since putting the phone in a case.
I've been having major GPS problems. Going for a run and expecting the phone to track my route and calculate my speed accurately shouldn't be too much to ask in late 2016. But my phone constantly loses the GPS signal (this was never a problem with my previous phone in the same location) and even when it doesn't, it can't figure out where I am. My run traces often show me two streets over in addition to thinking I'm jumping back and forth across a busy 5-lane road every 5 seconds or so. I run 6 miles and the phone thinks I've gone 8.25. Not useful for training for events.
Even if you don't want to use the phone to track exercise, there's another reason the bad GPS is annoying. It makes it impossible to take advantage of the feature allowing you to unlock the phone without using your fingerprint or pin based on your location. I have my phone set to be unlocked at home, but the phone apparently can't tell when I'm at home, making this setting completely useless.
As to GPS issues while driving, I haven't noticed them, but I've not used the phone for navigating either.
Would like to mention that while I have a case on it, it is quite light and doesn't seem like it should interfere so badly with the GPS. Will try checking the accuracy without the case and will update if this resolves the issues. Also, I have tried tinkering with the GPS accuracy settings but even selecting all the options to optimize accuracy has not worked for me.
The only thing you can do to test the case theory is to use the phone without that case. That said, it is possible you have a defective phone. I have read many articles about poor GPS being caused by a loose, internal connection. You might want to take your phone to a repair facility and have them check it out.
I have a US996 and, so far, GPS is nice.

No issues on my end yet, I use it navigating on a daily basis (racking up Waze points basically) and walking around, can't think of maybe one time it lost GPS driving and that was only briefly.
Mine was misbehaving horribly. I tried using google maps to see if it was something to do with Navigon, (my normal gps app) and somehow it seems like just running maps fixed it. It has been working great with Navigon now.
Go figure.

Am going to try nostock kernek v1.1 the updated version and see if I get a difference. Plus now am running magisk instead of supersu so will see if that makes a difference.
It's possible that the a-gps data is corrupt. I'm not sure how you'd go about clearing that. There must be a cache file associated with gps daemon.
Try installing this:

And when GPS isn't working, run the app and see if it's receiving/decoding any satellites at all (bar lengths indicate strength, colour indicates successfully received all ephemeris data from satellite and therefore has lock - it can take a while without a-gps).

P.s. I found that taking the back off my phone improves Wi-Fi. Metal blocks radio signals.
If you have low or no signals in a specific location, try popping the back of the phone and seeing if the signals become useable.

Is anyone experiencing problem with their GPS signal? Mine would lose the GPS lock constantly. Thanks.

Sorry to bring up an old thread. I just bought a used LG V20 (at&t version, H910) on Craigslist the other day, and have had GPS issues that made me highly annoyed like I bought a lemon phone, and was getting ready to call LG Support, and pay a lot of money for repairs.
Happily, I did discover a trivial solution that I haven't really seen, so I thought I'd share it.
After I purchased the phone, I factory reset it. It seemed like the device would be able to triangulate a position, but it would be unreliable, move around, and the accuracy would be highly variable. (observed in Google Maps and Waze). These symptoms seem to be consistent with other people's experiences. The useful and highly recommended "GPS Status" and "GPS Test" apps, that normally show visible satellites were showing ZERO satellites. As suggested in various places, I used "GPS Status" to re-download the A-GPS databases, set "sensor filtering" to medium. Still, zero satellites, but a semi-functional GPS, which is confusing. I found the hidden menu code for the H910 (*#546368#*910#), and SAAT->"Manual Test"->"GPS/BT/Wifi test" and ran the hardware-level GPS diagnostics. I was getting signals of 0.0 db for GPS and GLO satellites, kind of suggesting the GPS hardware was faulty, and made me even less optimistic/more annoyed.
I was basically convinced GPS on my phone was kaput, and would need to be serviced, until I discovered ........
Rebooting the phone solved all of the GPS problems, and made GPS and GNO satellites visible and now GPS is 100% functional. It seems that since I initially factory reset the phone and did my normal installation, I never did a simple reboot. Since I haven't seen that kind of obvious solution on any of the forums, I thought it would be useful to report. I'm cautiously optimistic that was my only problem ......
good luck

Bought a used one and having problems: it'll fix on several satellites but it's usually unable to acquire the specific location (latitude and longitude). Depending on the program, it will say "waiting for GPS fix" in osmtracker or "looking for GPS location" within 'GPS Status' (the app).
When it does get a 'Lock' (a specific location), its accuracy is 200-300m off. :/
I tried some of the other common tips and tricks:
I've downloaded new A-GPS data (using the 'GPS Status' app); tried using the GPS without my case on; doing a simple reboot, none of them work.
After more searching, I found this guide: https://imgur.com/a/VxeaU which recommends to place copper tape on the GPS antennas of your phone.
i have 2 V20's.. the one i bought back for myself is 12/2016 and another one is another batch 3/2017 for my wife..
What i'll found is the earlier one ( 12/2016 ) have the following issue :
- overheat
- kaput gps
- screen burn
While the one i bought for my wife ( 3/2017 ) doesn't even have the following issue above.. Furthermore, the screen also different.. my wife V20's tend to have a more saturated color, brighter screen and doesn't overheat as much as mine..
My conclusion is, only those with earlier batch of production have all this defect.. and to those who own it ( including me ).. i guess, we're unlucky!
i'll use my wife V20's as gps since mine V20 is good for nothing when GPS is a needs.... if she's not around, i'm totally doomed !

if you guys wonder, there was no different in camera.... unlike G6 ( pheww~ )
both my and my wife V20's produce the same images quality..

It's an old common fix

I followed that guide (credit https://www.reddit.com/r/lgv20/comments/7fx2gz/becareful_buying_the_top_plastic_bezel_of_the_v20/)
and bought copper tape (https://www.amazon.com/Copper-Conductive-Adhesive-1inch-12yards/dp/B018RDZ3HG) off amazon.
For me and my VS995; there were metal contacts (see picture 1 of the imgur album) and the metal contacts were silver, not gold.
Nonetheless, I put some copper tape only on the first contact as shown in picture 1 and my signal improved dramatically. The lowest accuracy that I can get (lower is better) now is about 8m and it has been hovering around 15m; and still takes a few seconds to
This is compared to my s5, where I could get an accuracy as low as 4-5m and usually hovers around 8-10m and could obtain my location within 10 seconds after turning on GPS.
