Does hardware version associates with GPS issue? - Epic 4G General

I would love to understand why so many people have problem with GPS. My always locks in 2 to 5 seconds within 10 meters since my first Froyo ROM which was DK17. I don't even need to do any trick to get GPS working. Mater of fact I am still using DK17 modem for DK28 ROM.
So if you have GPS Problem what is your Hardware Version? My is D700.0.5

Edit: My bad. Moderator, can you move this thread to general section? Thanks.

I've been having GPS issues since upgrading to Froyo. I have the same hardware version as u, D700.0.5

Same hardware version for me, Quantum 2.0.0 DK28 ROM, GPS not working.

I'd assume that those of us who have/had GPS issues have them because of the roms / tweaks we've monkeyed around with. My GPS worked OK stock, and broke at some point with screwing around with ROMS, and probably got worse with some 'tweaks/fixes' that I tried after that.
I ODIN'd the stock rom on there, got a lock in Maps, updated to the DK28 modem, and then flashed a DK28 rom, and my GPS works great again.

Please post questions in General section.

It could be very true since many of us are not very technical. We put our total trust on these devs (which I believe most of them are very good) and who knows what exact recipes for their appetizers are. Well that the fact that we all have to accept when we come to use these so called "hacked ROM" right?
Thanks.

Just because urs worked stock doesnt mean it worked for everyone sameway.. theres a uproar about this thing not for no reason.. mine is stock and ,5 version hw also and didnt work at all until i went to dk28-->di18-->gps lock-->dk28.
Now it locks within 5 secs with a 5-10m accuracy which is unbelievable for me.. i just keep looking at the awesomeness every 5-10 mins..
i never enjoyed watching gps lock like this anytime before in my life D

My GPS broke when I updated to dk17, so I read the forums and learned. GPS works on DK28, if you dont trust the devs then blame yourself for your problems, nobody made you flash.

The most serious of the longstanding GPS problems on the Epic -- the periodic failure to achieve satellite lock over time -- has been isolated to a software issue that theoretically can affect all units. The cause is that time-sensitive GPS almanac and ephemeris data stored in a cache is not refreshed properly.
The reason the symptoms do not alway appear for all users is that there are a variety of usage patterns that can cause the cache to get refreshed or cleared serendipitiously as a side-effect of user actions.
The common but temporary workaround for those afflicted is to change the GPS settings to Cold Start, and always use 3G data connections when initializing the GPS. This forces a refresh of the cache.
There is a also different but less serious issue affecting all Epics uniformly: The estimated accuracy reported by the GPS is a fixed, bogus figure of 30.0 meters (98.4 feet) instead of being calculated as a dynamic variable. This is not the same thing as actual accuracy, which is really pretty decent once a multiple-satellite lock is achieved, but some apps treat the 30-meter estimate as significant.
The latter problem is reportedly fixed in the various Froyo firmwares that have been tested. But there is no reliable evidence that the more serious cache bug has been fixed. Testing for that requires more controlled QA discipline than the chaotic xda community typically excercises, and few folks really understand the problem or know how to test the GPS properly, so the anecdotal reports are unreliable. (This has become more confusing because an unrelated problem in the act of flashing the updates appears to break the GPS completely for many testers. If they work around that installation problem, they think their GPS is "fixed." Maybe it is, maybe it isn't.) I have chosen not to install the leaked Froyo versions on my one-and-only phone, so I have not tested the GPS firsthand.

State of GPS on this phone ?

What's the state of GPS on this phone in todays date ? Did it ever get fixed to be as accurate as other phones ?
GPS files from a leaked rom has seem to "fix" the GPS problems. Personally, my gps works ten times better than it has before. Look under development for the files. You need to flash it using clockwork.
Sent from my messenger rabbit
lets get more opinions on here
I have never seen a lock on mine until I flashed the leaked GPS fix by itself. Then everytime I look I see at least 10 and lock on 5-6 at least.
Same here. GPS was all but useless, even with the original fixes. On a very lucky try I would lock 3 sats, but that was extremely rare. Usually the norm was between 0 and 1 locks with location accuracy being within 1200 meters.
Last week I flashed bionix 1.3, which includes one of the fixes, and now my phone will consistently lock to a minimum of 5 and sometimes up to 9 satellites.
It's still not perfect and my location jumps around a bit, but it is accurate to within 50 feet and this is acceptable for my use.
As far as I know there is still no reliable word on an official fix from Samsung as they are busy releasing all sorts of wonderful new tablets and such.

Same as everyone else: none of the "fixes" worked for me until I used the JI2 leaked GPS files. I flashed with Clockword Mod and I get fast, accurate (~7 meters, which is good enough) locks.
After flashing JI2 GPS has worked every time. For over 2 weeks now straight .. fixed for me 100%
I tried the I9000 JPK Froyo on my Vibrant and get a GPS lock as soon as I opened the map program. good news is coming for sure.
i'm still running stock everything, and i can lock anywhere between 2-6 satellites when outdoors. indoor reception is very poor
Zero problems here .
Just turned on the gps and have lock in 9 satellites.
Still no fix for mine. I think its just broken but I don't want to Send it back because I'm afraid of a hardware locked vibrant.
After this post, The XDA app probably forced closed from my froyo lacking Vibrant
sorry but what app are you guys using to 'lock' satellites?

An app doesn't "lock" a satellite -- the Vibrant (firmware) does. If you use LBSTestMode, you'll see which satellite signals are locked by the asterisk [*] at the end of the signal strength.
Alternatively, if you use Google Maps or Navigation, when the blue circle disappears, it usually indicates you have accuracy <10m, which is good enough for street navigation. You could consider this an informal "lock."
GPS status
There are also apps in the market that will show you locks and more info. I use 'GPS Status'
I initially applied the JI2 leaked update, followed by JI4. Using the GPSTest app, I was able to see a lock on to at least 6 satellites within 5-6 seconds, eventually going up to 13 satellites, depending on how many were visible at the time of the test. The leaked update definitely fixes the satellite lock and compass issue, although the GPS still experiences some very minor inaccuracies as far as positioning is concerned - nothing that renders it useless, though. As far as the official update is concerned, it sure looks like Samsung will not be able to live up to the promise of a September release.
yup, I Knew Samsung wouldnt fix this in Sept. OTA
Who cares, the leaked Rom/Custom roms with JI2 work just fine.
Id rather have that then a stock Rom anyways from Samsung.
I have not 1 issue with this phone other than samsung is backing it. No issues now GPS has been resolved in JI2. For me, its good enough to get me where I need to go.

Agreed. Other than the occasional lag, the phone is pretty much 99% functional applying the leaked update. The problem definitely lies with Samsung, though. A lot of Samsung's apologists say "be patient, they are working on it, it'll be out soon, blah blah blah". Based on the leaked updates, it's painfully obvious that Samsung is working on it; however, based on an average lifecycle of a phone (2 years, give or take a couple of months), 10% of the Vibrant's life is already over, and still no official update. I'm definitely not one of the "I'm selling my Vibrant and leaving T-Mobile" people, but the stalling of the OTA makes me question Samsung's approach to future updates.
JI2 has made the GPS good enough for me to not ditch an otherwise great phone. I get locks on 6-10 sats at all times as compared to 0-2 before flashing.
I'm not surprised, however, by Samsung's silence regarding this issue. Unless they shock us with a massive push of a fix by Thursday, their reputation in the cell phone world will continue to slide.

Captivate Froyo Leak

As we are aware that there has been a official Froyo release for the captivate. Ive done some reading and cannot find conclusivly if things have been fixed as this may well be a good view of what the international version will look like.
The questions i have is
1. Is the GPS fix a completed fix and all is now well with teh gps.
2. Is JIT enabled and does it improve the speed.
3. Is the lag issue no gone or will we need to do a lag fix.
4. What other improvements are there? and whats not fixed?
Cheers guys if anything this will allow us to discuss the leak from our i9000 point of view.
You know there's a thread for this in the Captivate forums, right?
To save you some time, here's what I've gathered from the mammoth thread:

It is unlikely that lag has been fixed as Samsung is still using the RFS file system. The problem with the lag is that it gets worse over time so even those claiming they have no lag immediately after installing new ROM will probably get it after a few days.

Leaked FROYO on Captivate - excellent so far
ATT Captivate
One of the pre-Nov 6, 2010 Korean machines - and, yes, it has had the random turn-off issue both pre and after upgrade to FROYO.
Use LauncherPro for the Home Screen.
Used SuperOneClickv1.7-ShortFuse to root.
Working around the random turn-off with NoBars app - we'll see if it works.
RESULTS:
Phone is WAY faster than 2.1
GPS works fine
Good new additions and look in Settings
Apps I use simply do NOT FORCECLOSE! ...like some did incessantly with 2.1
Of course, voided warranty, but phone is now fast, stable, and seems to be much more reliable.

ATT Captivate FROYO update re random shut-down....
Well, I know there are threads about this - ones I've seen are closed.
So, a quick update just in case anyone finds this useful:
The random shut down continued, despite NoBars app.
Installed APN OnOff. Turned it ON, disabling 3G/EDGE/GPRS, and after 3 hrs, no turning off. Turned it APN back off, and noticed the screen would go blank, and I could bring it back by pressing power button without then having to enter my security code, every time something accessed 3G/EDGE/GPRS. Put phone into standby - shut itself down within 10-15 mins.
Solution I am trying: following above I went into sync settings and disabled Background Data, and Auto-sync. So far so good - no shut down.... if it does, it does look like the APN OnOff app will prevent this, you'd just have to turn it off when needing to use the 3G/EDGE/GPRS.

GPS STILL wonky?

I am running an unrooted stock vibrant. I got the Ji6 update a few weeks back, and I was told that it would improve my GPS. But apparently my GPS still doesn't work. I know there are alot of tweaks and hacks here on xda that supposedly fix the gps, but id rather wait and get the official fix from samsung. But if the ji6 was it, then im quite dissapointed. Does your stock vibrant still have a wonky GPS? Or did the update fix it for you?

GPS works great!
I am running Bionix 1.9. Last night on my way home, I was in an unfamiliar area on a small side street and got a little lost. I turned on my GPS and opened up Google Maps. Within two seconds it locked me in and gave me directions home. I noticed the address at the top of the screen where it said I was. I looked over at the house number and street I was on and it was exactly right.

I've never rooted either, and for me it's still not perfect. Sometimes it works well, but other times the location jumps around, or the phone hangs and has to be rebooted.
I've seen an improvement since the JI6 update, but my experience is if you use it enough you will encounter flakiness still.
Would be nice if subsequent updates improve things, but right now that's just a hope.
Yes I had a similar experience, with my stock vibrant which has the j16 update. Took over 5 mins to lock on to the gps signal.

I believe it's just plain bad hardware, and it's not competitive with most other current smartphones.
I've tried a bunch of ROMs, with similar results. The update gives you a faster lock and an accurate report on the number of satellites, which is nice, but it doesn't do anything for the core accuracy problems which plague the device and cause tracks/navigation issues. It doesn't help that the compass is also still very wonky, which causes Google Navigation to flake out when I'm stopped at a light.
All in all, it's very disappointing. I'm thinking of switching to the Nexus One due to this issue.
I've got an unrooted Vibrant bought in July 2010 whose GPS rarely worked and almost never locked on any satellites. After J16 I get a quick lock on 6-9 out of 11-12 satellites. I am satisfied with it now 99% of time for navigation purposes. I do sometimes get wandering of the target from Google Earth even when standing still.

I'm not so sure about that. I hooked it up to my bluetooth GPS and it looked good for a little while, maybe a few minutes, when sitting at my desk. Then it started going wacky, progressively bouncing the pointer farther and farther from the real position. It might be the software that's bad. I'm going to experiment with it tomorrow on a long trip and try various settings.
Its a hardware problem..

I have to agree. I had the built in car navigation and the vibrant side by side. The vibrant is 200 yards behind while moving. Even when pointing on the current location, it is wondering around the neighborhood on a 200 yard range.
So what's your explanation for what I see with an external GPS which works fine with a laptop? That a phone hardware problem too?
As far as using the internal I've seen it work for an hour fine and then start flippin out. Then again I've seen it flip out in 5-10 minutes.
Gps is one of those things I rarely think about until I have to actually use it. I just came from a week trip to Atlanta and it connected once during my week stay. The GPS on this phone is crap, I feel bad for anyone that has to use it daily. Luckily I got 3g there and was using google maps to help me find locations. My recent devices Milestone and HD2 connected within seconds. This thing is always searching for a signal with a clear view to the sky.
Im in North Florida if that means anything.
i ran bionix final which i think is the ota ji6, not the kies leak ji6 and the gps didn't work well. but the ji2 gps flash worked great, and the ji6 gps in bionix fusion works great.
you are posting on xda, if you just want to complain go to tmonews or something, otherwise there are a lot of easy fixes that are like 5 clicks away...
GPS works fine for me on JI6, however there seems to be a communications error between certain Google apps and the GPS. I use CoPilot. On Bionix Final my GPS went from good, to ok, to bad, to horrific in a matter of days.

I can assure you that at no time did I ever go 118 mph. This is just one sample. It does it all the time. I've tried every different firmware I can load including stock and I get the same results. I've tried all of the GPS fixes and nothing. Some days it never even locks. I'm convinced that it is a hardware issue.
GPS works for me most of the time. Sometimes it will show I'm in my house. Sometimes my neighbors. Sometimes down the street. A few times across the city.
I wish it was half as good as the wifi. This thing can pull in an access point like it had a high gain directional antenna built in.
I'm even more convinced it's the software. Now my external GPS won't lock either. Sees 12 sats, I can see the data coming in, but it never locks any sat.

For those of us on 2.2.. GPS?

How is GPS on JK2 for you? Accuracy is greatly improved during navigation. I want to see how good or bad GPS is working for you guys.
If you have nothing to lose/non-functional GPS, flash this via Clockwork and let me know if you see any improvement..

Does this work on t-mobile, AOSP ish 1.1 rom with stock kernel?
I've been locking 11/13 satellites near home and this is the first time I've gotten an accuracy reading under 10 feet since I had my G1. Then again, I've always had pretty good GPS results from JFD on. I think that some people may never get a good GPS reading because Samsung's quality control is not up to snuff and it's a hardware issue for some phones.
My GPS is still just as inaccurate as before. It will "lock" on to 8-10 sats but it still bounces all over the place using MyTracks. The accurace indicator sometimes gets down to 25 feet but it is a total lie as sometimes when it says 25 feet it has me pinpointed a half a mile away. I've tried all of the sittings/clear data tricks I've read and still no go. I don't think there is a software fix form my GPS that will work.
no idea how many satellites it locks onto, but when I actually use it for navigation, it's much quicker and accurate. Of course, my GPS was pretty good before JK2 on JI6.

That's why I requested a refurb myself. I have a spare battery and of course another back so I will test them both to see if they're any different.
I tested a Samsung Captivate and it got locks quick, down to 5M in seconds. More importantly it accurately reflected my position on the map. The software is obviously different in operation tho, it only showed 5-10-15 meters exact of accuracy and nothing in between.
I had no problems Google navigating on JK2 either. JI6 is a different story with Google Nav. 10 meters of accuracy quickly turns into 40 meters for no reason at all. So if it is a flaw, it can be "optimized" via software, but if it's a flaw in the GPS chip/antenna then it might be corrected on later build dates (and refurbs if Samsung took note) and the GPS could be as good as it should be.
Not sure about that rom, but Nandroid. I had no problems flashing it over, it didn't break anything that couldn't be fixed with a restore or reflash.
Im on the ODIN JK2 from eugene and I think so far its the best GPS Ive seen on a ROM.
With eugene's JK2, gps was back to sucking. Would get 10 or so satellites in view pretty quickly but would never "lock" or get any sort of usable reading. Too bad, cuz the rest of the rom rocks.
Before JK2 my GPS didnt work at all. After JK2 its amazing!!
When running GPS TEST I get anywhere from 10 to 12 Sats and lock on to 8 - 10. I've gotten accuracy down to 10 feet (in a moving vehicle) which is awsome!!

vibrant does not use jupiter.xml sub-system, so this fix that you want people to try will not work on vibrant.

I wouldn't know, I asked because I wanted to see if anyone noticed a difference at all.
I get quick locks now, but still not very accurate. Most of teh times it shows accrate within 100 feet or so. Often my actual location is quite a bit outside of the "blue spot" on maps.
No improvement. The original 2.1 update improved locking speed and the number of reported locked sats, and 2.2 seems to exhibit similar performance to that.
The GPS is just generally poor on this device for me. It works in a pinch, but I hate relying on it because it's likely to flake out and report me driving through a field or a building at a critical time when I need it to be working.
since I flashed the JK2 leak I am actually getting lock indoors which I never got before
Anytime I flash a new ROM I need to try digitaltoddys *#3214789650# trick... after I do that, I ALWAYS have amazing GPS. I can't recall all the steps, but it's listed multiple places, and I placed it in the sticky. If you are having issues, STRONGLY encourage trying it. Doent seem to fix it for everyone, but its night and day for me.
My GPS on the JK2 leak has been amazingly much better than either the original JDK or the JI6 release. I also can get locks indoors now which is great. However I haven't been able to get the accuracy to closer than 15 feet. So wished that could be a little better.
Running Team Whiskey's Obsidian v2.2 and GPS works really well for me. I consistently get a lock within a few seconds with 7-10 meter accuracy, and if I give it time it will actually get a lock from within my house, which is crazy.
obisdian v1 gps didn't work for me. obsidian v2 and onyx v2 both got my gps working (again).
I'm using Obsidian V2. Seems like when I use Maps I can get within about 30 meter accuracy. Sometimes less.
Navigation is a total joke though. Jumpy as hell, can't tell where I am half the time etc.
My gps is accurate in obsidian V2. Opening wifi is improving the accuracy of the gps for me. If turned off it's 1100 meters away from me and if it's turned on it's 9 meters accurate.

So does your GPS work?

Mine works with S.GPS fix / with Darkys rom
It is made on JUN 2010
The GPS always "worked", it's the matter of how "well" it works. Drifting all over the place at red light and have accuracy > 50 meters is not considered working well.
I am also using Darky's rom, and my gps is spot on. It pinpoints me in my house. on navigation, it is alway right there. mine was made june 2010
Mine works after the hardware fix with solder. Before that it was unusable. Now it "works" as well as the software allows. With Bionix V 1.3.1 and Jellete's patch it usually locks within 20 seconds, but accuracy varies greatly. Sometimes its flawless, sometimes its unusable.
If you are having problems, use Heathen GPS fix, Masters GPS fix or download the app GPS Aids from the market. they will resolve your gps issue (one will) OR just get a decent rom that has it in it already like the Trigger or Axura
I have had two Vibrants. I've tried every fix out there while the fixes improve the GPS nothing truly fixes the GPS. I've tried the Hardware fix (bending the antenna) and all sorts of software and setting fixes. Currently with my new vibrant is better with the hardware fix, darky's rom and Jellett's GPS fix, but is it close to my G1 or G2? No, there is no comparison.
As an earlier poster said and I agree, the GPS is not broken but it barely works, it loses signal and does not pin point your location is a respectable time.
GPS with this phone is a C- at best.

if that is the case then IMO, it's unusable or defective. GPS should be reliable all the time, well as long as it can see the satellites. If the phone dropped calls or failed to sent txts at much as the GPS gave issue would you still have the phone?
I really like my Vibrant, but GPS is useable but that is all. My HTC phones gps would locate me within a 5 foot radius as I took a walk. I don't think the Samsung gps ts capable of that. The Vibrant GPS has never shown better than 18 feet accuracy and it comes and goes as you move.
Much to my surprise, no it doesn't. I tried flashing the s.gps fix but its still useless. I'm running trigger 2.8 with its recommended trigger kernel and both are supposed to improve the gps not screw it up, what's wrong!
Btw, it was functional before so its nit a hardware problem.

Not before the hardware fix. Now it works wonderfully. Quick locks, good accuracy, no drifting. My combo is Bionix 1.3.1 with Heathens GPS fix and the hardware fix.
I have tried everything to get this phone gps to work. And when I say work I mean work like a normal gps ie.. less then 15 foot accuracy lock in 10 sec hot start everytime and no wondering at all. On top of a parking garage at work with a 360 horizon view and no clouds at all I can get 8 says to "lock" but it shows the blue circle 50+ feet away from my actual position and the center of the circle 70+ feet away. The gps on my phone has never worked and I have done every fix out there including hardware, which I thought fixed it bit then found out it did not. Right now I am hoping that the t-mobile gx2 wont have these issues as that will likely be my next phone. So those of you that think your gps os fixed let's see some "my tracks" in comparison to a known working phone like the nexus one, my other phone that blows the galaxy out of the water on gps. I am betting that you will see that it really doesn't work at all.

Maybe yours has a hardware issue. I run Tigger 2.8 with os kernel. My gps is not great but it is usable and serviceable.

Ask for a replacement. The GPS on my phone was crap, would lock on after a few minutes then lose position, could see 12 birds in the sky but won't lock on any one of them, and if it did work I would magically fly through houses and roads when I was driving my car. I got a replacement and it works flawlessly out of the box. Locks on within 30 seconds, accuracy depending where I am is anywhere from 10 meters to 4 meters. It has a few hiccups but I attribute that to where I live. Only problem now is that the GPS fixes in Bionix 1.3.1 kills my GPS. I am unsure why.

Have you tried any of the fixes by the devs?
My GPS works like Sprint's network. Many claim its great, but it kinda works and it really sucks.
I don't have a problem with it locking when I'm stationary. The problem comes when I'm driving. GPS loses lock easily and jumps around. This leads to unnecessary reroutes and general confusion. It's borderline unusable in unfamiliar areas where you actually need the GPS help because of the random reroutes. The fact Samsung gets away with this kind of product defect is a reflection of current govt incompetence/corruption.
Mine works perfect with Trigger.
Spoke w/ Tmo rep, they said to download "GPS Restore" (a samsung app) from the market to fix gps issues. Don't know if anyone else has tried this but I have and it actually helps a lottt.
