OK, you punch those numbers in to your dial pad, open your dial pad as if you are going to phone somebody, and punch them in exactly as described.

After this, you should get a menu up.

Click on Application Setting, scroll down, and select Use SkyHook and select yes
[Galaxy S I9000 General] gadjet0:
Thanks for the code, I've switched on Skyhook, we'll see if it's better.

One other thing I tried (before switching on skyhook) was to look at the GPS test and with that I got about 8 sat's in around 20 seconds I had a 10M accuracy fix, this seemed a lot quicker and more accurate than I got yesterday with google maps!

Also is there anyone using Copilot or other navigation SW I would be interested in your feedback on performance.

Cheers.

This article :

http://www.engadget.com/2010/07/02/skyhook-hones-in-on-another-partner-samsungs-wave-to-geo-locat/

suggests Skyhook is some location service based on internet, cellular and GPS data.

Not really reassuring for people getting into no-coverage areas.

whe i first used it without simcard the gps was really good, (used wifi also)

but with wifi and simcard, the locatation i fairly stable, only that it pinpoints me to a location far,far, far away in another city!

I tried a program named gps status and seems to have 1 green dot (satellite?)

Any way, removing the simcard i suddenly get a bunch of green dots. (have anyone tried that?)

(i use wifi at home) when i'm outside using 3g network i think it's fairly good, but iä'm not sure.

Hope it's just a software bug and not hardware related, i don't want to return this...
[Galaxy S I9000 General] TravUK:
I removed the SIM card, but it's still doing the same thing. I think you probably just had a fluke where it started working again.

From the poll I see we have almost 60% with either intermittent or constant GPS issues.
[Galaxy S I9000 General] boo6:
a typical image:

the Galaxy S has the better reception, but it doesn't link to sats under 20dB SNR and it doesn't linkto more than 8 sats.

(15dB, like on the desire are currently not possible on the gS)

nothing has changend on this on the current JG3 FW, but it seems that the links aren't dropped that often.
[Galaxy S I9000 General] s.m.knipe:
To the earlier question about why they don't use the GPS chip from Garmin, etc., I think they actually, but those car GPS ones are programmed to "snap" to the roads expected. Pay attention to when you exit a freeway, it sometimes shows you going the way it wanted you to briefly...
[Galaxy S I9000 General] Balthazar B:
EXCELLENT POST! Should be required reading for *all* Android kernel developers...

Or at least for developers working on Android platforms that use location services...

Hmmm...that would be *all*...
[Galaxy S I9000 General] sjdean:
Yes, I would be interested in this too.

I will continue to maintain a list of links that we can post over on the forums to try and get a broad experience. Pictures, Videos, etc, all will be useful in proving to Samsung the problem. Wondering where I should store this list?

The first guy I spoke to at Samsung told me that he wasn't familiar with GPS but to send an email.

The second person I spoke to, when I asked about firmware upgrades, said those are down to my service provider. I told him my phone is off contract. He then said firmware upgrades are down to Google. I kept telling him he's mistaken and he basically called me a liar. I made a complaint but haven't heard anything.

Then I spoke to the first guy again in Samsung Galaxy S support who advised that there will be no new firmware until FroYo is released.

The email responses I've had in relation to my weak GPS, say that I should go to the Applications button and Launch maps. I can also use Layar.

Bunch of idiots. The lot of them.
[Galaxy S I9000 General] Balthazar B:
Take a look at Post #6 in the GPS Problems Possibly a Hardware Issue in this forum. Looks likely a kernel fix will be required.

[Galaxy S I9000 General] nicoloco:
I am not sure it will have any impact on Samsung, unfortunately.

By the way ... I did an other run this morning and I must confess I was almost happy witht the track :

http://maps.google.com.au/maps/ms?i...426,151.274335&spn=0.010171,0.022724&t=h&z=16

It it not perfect but honestly that's good as there is no crazy loop and the distance is pretty much accurate

Even the graph giving the pace was quite good ( I did some intervall and the pace quite well followed what I did)

The difference with yesterday's track : I am using 2G only ( as I wanted to test my battery overnight without 3G) and this morning I was close to the beach and not in the city meaning almost no building at all, no trees, no cloud ...
[Galaxy S I9000 General] AllGamer:
no way, i quite disagree with this, my HTC Athena works horribly when i use the Sat data download thing

when i turn it off, it can find satellites better, than when i leave that download on

there is most likely a bug in those data, and it's not compatible with all the countries.

it supposed to make finding satellites faster, but instead it does the opposite.

if i leave that feature on, it will never lock into any satellite, as it tries to find some satellites that are not even there.

I think people having problem with SGS are having the same problem, but in the opposite direction.

SGS with the aGPS on, works great for me, but it doesn't for some people, so it must be the satellite telemetry data contained in those download that it is trying to find and can't locate.
[Galaxy S I9000 General] sihayqueirseva:
Working good for me in a SGS i9000 simfree, I9000XWJG1, mimocan fix. Gps test much better, i will test tomorrow using car navigation.

Thanks a lot. Regards from Spain.
[Galaxy S I9000 General] appelflap:
As far as i can see it's an firmware release by www.samsung-firmware.webs.com, which isn't in any way related to the Samsung cooperation (except that it has all kind of sources to pull alpha and beta releases from Samsungs servers :) )

So the exact status of this firmware isn't known. It can be still alpha, meaning that they are intensively testing it "in house".

Nevertheless, the best part of this all is a) the problems doesn't seem hardware related and b) They are really working on a fix!
[Galaxy S I9000 General] larryccf:
thanks - i learn every day - i had assumed it was samsung's website
[Galaxy S I9000 General] Beards:
Has anyone had a read of this item from T-Mobile Community Vibrant; it lists clearing the cache data from the bootloader screen.
[Galaxy S I9000 General] andrewluecke:
That is unlikely to help.. At the best it might fix the first lock (which isn't an issue in the latest rom's anyway).. But in JM5 at least, the signal still drifts even when sitting in a single location (and the accuracy is incorrect).
[Galaxy S I9000 General] BenEadir:
Hi all,

I have a stock SGS running 2.1 update1 and I simply can't get GPS to work with Google Maps Navagation whatsoever. I constantly get a "Searching for GPS" message but despite sitting outside for up to 10 minutes at a time it never locks onto a satelite.

I saw post suggesting the following settings but they don't seem to have made any difference. The settings are:-

1. Disable “Use Wireless Networks” (Go to Settings > Location & Security > uncheck the box next to “Use Wireless Networks”)

2. Go to the phone and dial *#*#1472365#*#* (This step throws you into LBSTestMode menu)

3. In the LBSTestMode menu change “Operation Mode” to MS Based

4. In the LBSTestMode menu, find “SUPL/CP Settings” and change the Server to Auto

5. Turn Sky Hook on

6. Restart

7. Enable “Use Wireless Networks” (Do this by reversing what you done in step one)

Can someone with better knowledge than me comment on the above or even better supply me with instructions/settings so I can get a basic level of functionality for in car navigation with Google Maps?

Cheers,

Ben
[Galaxy S I9000 General] TravUK:
Hello Ben,

Unless you feel confident upgrading to an unofficial Rom, its best to wait for an update from Samsung. The default Roms that shipped with the phones have a number of bugs relating to GPS, and there are no 'fixes' that actually solve them.

With the default Roms, when GPS isnt working, the single most useful thing you can do is disable and then re-enable GPS. From the menus go to (Settings/Location and Security/Use GPS satellites) on earlier Roms, or using the GPS hot switch on the drag down menu on the home page from some of the later Roms.

Then its a matter of patience, waiting for Samsung to release the full set of fixes.
[Galaxy S I9000 General] Beards:
Mark,

Can you do me a favour and check Kies.

I've been told there's an official JM1 available.

I'm busy in theatre today and don't have time to go check myself.
[Galaxy S I9000 General] TravUK:
Hi Mike,

Yes the updated was issued via Kies on Wednesday, so I'm guessing you've not tried for a couple of days. The update went smoothly enough, and there seem to be some data/signal improvements. Other changes were subtle, but there is now a handy GPS hot button on the home page pull down menu.

It doesn't contain the GPS fixes, anything leaked before August is unlikely to.

And as had been warned, the update will wipe and reset the phone to a factory state.

Mark.
[Galaxy S I9000 General] Beards:
Ohh... thanks Mark.

Yes, you are quite correct, I've not had chance to load Kies since Tuesday and most probably won't get a chance until Sunday at the earliest.

Reading what you say about it not including the GPS Fix makes sense and was my main concern in asking if this was a new update that addresses the problem.

So if this does not sort out the issue I'll most probably hang on and wait for the next Official update.... unless you believe it is of benefit that is.

I back up using both Sprite and My Backup Pro so hopefully getting everything back up and running should go cleanly..... fingers crossed!
[Galaxy S I9000 General] TravUK:
If you're happy with the rest of the phone, there's nothing life changing about the update that you'd be missing out on.
[Galaxy S I9000 General] Beards:
Thanks again Mark..... That'll do for me and 'hopefully' we will see the mysterious GPS Fix surface soon. :)
[Galaxy S I9000 General] sihayqueirseva:
It' strange.. I have did the fix without problems, the lock improvement is good; but in copilot, google maps, sportstracker, etc... the recorded routes are much worse than before. It looks like that the sign gps is recording "delayed".

Nevertheless, in the Gps test both the number of satellites (view and lock) and the strenght of the signal is better.

I don't understand...
[Galaxy S I9000 General] Tyxerakias:
TravUK, could you do me a favour and check whether Swype now includes the Greek language? (Ελληνικά). From the leaked JM1 reports I would assume it did, but can't be sure of course. I'm going to install it tonight, and this would be something life-changing for me.
[Galaxy S I9000 General] poolcin:
I am sorry to say that, but i can not see Ελληνικά in swype config. There are: US English, UK English, Deutsch, Français, Español, Italiano, Nederlands, Português Europeu, Polski
[Galaxy S I9000 General] Tyxerakias:
Hmm, that sucks. Thank you for checking though!
[Galaxy S I9000 General] appelflap:
I tested the new Captivate GPS fix today, but although it seems promissing, it still isn't a full blown fix. Yes, the gps locks on to over 8 satellites and it doesn't need a snr value of over 20 anymore, but it sometimes does take forever to get a fix.

I noticed that there isn't any LTO.dat anymore in the /data/gps directory which could mean that the LTO (long term orbit) support is temporarily disabled. That could explain the long time it takes to get a fix.

It is definitely "work in progress" but it looks very promissing.

Going back to the old JM2 firmware, feeling comfortable that a fix is on its way ;)
[Galaxy S I9000 General] larryccf:
don't know how much this bears considering, but over on the Tmo site, some are reporting their standalone garmin units are "hiccupping" and loosing track of their position, and attributing it to the solar flares that are supposed to start hitting us today

ie, wiping out the GPS satellite signals

whoops, thought i was still in the captivate rom forum
[Galaxy S I9000 General] aurelm:
On foot - perfect. Good lock, accurate, many satelites.

On car (bus) - horrible. Good 5m fix, forgets to move. It just stays in a single position and after 30 seconds it starts moving after the vehicle, always 30 seconds behind until eventualy loses lock. Wtf ? How is Samsung testing these things ? Just on the balcony of the office ?

Also noticed something strange. After installing the jm5 fw everything ran fine. After 4-5 days it went to hell. Also with jg5 firmware, at the begining everything fine. Also with the stock firmware. Something tells me that there is a lot of garbage data in a file somewhere that makes the gps fail after some time at every software update.
[Galaxy S I9000 General] Beards:
Latest from CLove:-

Mike

We have been informed by our Samsung representative that the update for the Samsung Galaxy S i9000 should now be available. The update has been attempted within Clove Technology however the Samsung Kies software failed to find any updates for the Galaxy S i9000 which we connected. A request for additional information has been made and we are currently awaiting a response from Samsung. The update may appear over the weekend and we will be checking on Monday.

Here's my review on the latest "fix.

It's bad. Real bad.

I don't think it's a fix at all, it's the Captivate or Vibrant bits of pieces. Looking forward to the real fix.

Yesterday I was getting 10 satellites, 10 locks.

Today I tested with MyTracks, and while it wasn't showing wild loops, everything was severely delayed and shwoed me 30 metres off to the side.

Another test walk, and at one point I had old familar with me making a 90 degree left turn, the system still showing it had lock, but making me walk straight on instead of turning left for about 60 seconds before everything caught up.

I restarted and noted that a "perfect" 5m lock showed me about 200 metres away.

I removed the /data/gps folder and started noticing that I was getting about 4 or 5 satellite locks if Im lucky.

This was actually favouring satellites pretty much overhead and ignoring anything stronger on the fringes. Plus it took ages to get a lock, even when it had the sat position, it wouldn't lock on for at least another two minutes.

Poor poor poor.

I want it to lock onto everything to improve stability, is that too much to ask?

Not that I think more satellite locks will actually improve the position, as the underlying NMEA data reflects frontend Android.

Cya

Simon
[Galaxy S I9000 General] Case_:
Yes, and also the track recording is mostly the same, meaning bad. BTW, are you testing it with the full Captivate firmware still, or did you just flashed the usual i9000 firmware back and test it by copying the files?

I have the feeling that this update their Samsung source mentioned is in fact the JM1/JM2 firmware update rolling out everywhere. And if so, then it means no GPS fix yet.
[Galaxy S I9000 General] fakekullu:
Layar, GPS and lots of heat

I was just using Layar and GPS (which rocked!) but almost instantly my screen and the top left corner of the phone's backside got hot.

Has somebody else experienced this and if yes then what's going on?
[Galaxy S I9000 General] sjdean:
Someone asked for the "update.zip" that I generated to get these files on your phone as gps_fix.zip don't seem to work for many.

Note, this also gives root access :-)

rename the file to update.zip and put on your mem card and use the normal procedures to get into recovery mode and apply update.zip.

Don't know if it'll work on other phones besides mine, but if it works, grrr8.
[Galaxy S I9000 General] strangnet:
I installed the proposed fix last night, and initially it looked good. But today, after having entered the *#*#1472365#*#*-menu and tested the settings there, I at first only got 1-2 satellites with no lock and after a while no satellites at all. Don't know what happened there. Luckily I had a nandroid backup I'm reverting to now.

I also had a look in gps.conf with root explorer, and on every line as a last character there was some kind of unidentified garbage character (showing up as a rectangle (a char not in the charset)). I removed those; could that be the reason for my problems?

Running a stock JF3, btw.

Samsung announces 'software to optimize GPS' in September

At least there is now a date-range to look for a fix optimization: September. See tweets at GalaxySsupport

To call it a fix would be to admit that something is broken. :rolleyes:

Here we go again! :rolleyes: I'm not holding my breath!

So like some of us suspected it will probably be rolled out with froyo.

Don't shoot the messenger..... If you don't want these updates I'm happy to leave them out.
[Galaxy S I9000 General] TravUK:
That timeline would seem about right.
[Galaxy S I9000 General] enigmameusa:
Or they will keep on delaying it because they can't fix it?

"Firmware fix next week"

Several weeks later....

New official firmware released, no fix.

"Firmware fix next month"

.....

I hope they can fix it, but either it's very difficult or they don't care it's not working. Hopefully it's just difficult, but the galaxy has been out for quite a few months now
[Galaxy S I9000 General] larryccf:
sjdean

don't how much bearing this might have on the results you got, but there was supposed to be the effects of the solar flare activity hitting the earth, starting Tuesday & not certain how long it's supposed to continure for - but some of the folks over on the US Tmo website were talking about their standalone garmins were dropping satellites and pulling screwy stuff

here's one news report on the solar flares - it's strong enough that some were worried about the electrical grid going out

http://www.foxnews.com/scitech/2010/08/03/spectacular-northern-lights-signals-sun-waking/
[Galaxy S I9000 General] Beards:
Yes, I've just heard there's a tweet from Samsung stating September...

I'll call Clove on Monday.
[Galaxy S I9000 General] boomerbubba:
The way I read that story, it is 10 days old. It says the solar flare was expected to affect the Earth on Aug. 4.
[Galaxy S I9000 General] appelflap:
Tested it on the Captivate firmware. I wanted to sit in the front row :)

I'm having a good feeling about it. Sometimes it gave me a firm and steady fix with a great accuracy for quite a reasonable long time. But its definitely not release material. Again i'm happy to see that it's not a hardware problem and that they are working on it.

Samsung testing GPS Fix - coming next month

well well well, looks like Sammy isn't doing so bad with the SGS :D

http://phandroid.com/2010/08/13/sam...ftware-fix-due-september-for-galaxy-s-phones/

Just read this article on Phandroid and Samsung are apparently testing a GPS fix for the SGS, and the other models (fascinate etc etc). No word on whether it'll be bundled with the official FroYo ROM but i think it will be, what do you guys think?

Let's see what Sammy churns out this time ;) i'm glad Samsung are actually releasing FW's and fixes for this phone, i got the i900 2 years back and the support was horrible with that! :D

keep em coming Samsung!
[Galaxy S I9000 General] sjdean:
Well that article is from last week, references Tuesday, and it's now Friday. So, not the same issue IMHO.
[Galaxy S I9000 General] sjdean:
Again though, it was announced in March, it's been in release for around two months.... and they didn't pick this up during testing and still haven't got a resolution?
[Galaxy S I9000 General] TriC_101:
I don't find mine that bad but this is good news...
[Galaxy S I9000 General] dakine:
Notice how they say nothing about the i9000, it's like samsung just won't acknowledge that it has a problem.
[Galaxy S I9000 General] MAMBO04:
Yeah but tbh its amazing that they are even acknowledging the problem in the first place! Tbh GPS works fine in my i9000 but still this is good news for others
[Galaxy S I9000 General] sewe:
The "fix" really change my GPS,finally I can use it tnx,

didn´t lose a satelit for several hours when I was driving and before the phone lost the signal after only a few km
[Galaxy S I9000 General] NZtechfreak:
My GPS is fine too, but if this makes it even better it sounds good.

I agree with the above poster, seems likely timeframe wise that this will be bundled with the Froyo update.
[Galaxy S I9000 General] Beowulf_pt:
Let's be realistic. It will never be fixed past mediocrity, if at all. Hardware issues like poor antenna design might also be impossible to circumvent.
[Galaxy S I9000 General] appelflap:
Now you are just trolling. Just looking for some negative reinforcement :p Well here you go:

The track someone posted in this thread with the Captivate test rom was actually better than mediocre. Tests I did with the new Captivate fw did see an improvement in the steadiness of the lock and a more fine grained fault tollerance (5m - 10m - 15m - 25m steps instead of 5m - 10m - 30m). Clearly not all features are enabled in the new test firmware. LTO is disabled and I think aGPS is disabled as well. I'm very confident they will fix it.

BTW have you tested the poor antenna design hypothesis by attaching the mmcx antenna you've ordered? ;)
[Galaxy S I9000 General] boomerbubba:
I would not be so quick to lose hope. That is why I still own my device, although I am prepared to unload it at a loss if need be.

I have been as suspicious as anyone about whether there might be some hardware issue as part of the root cause, mostly because the manufacturer coyly refuses to rule that out. But I know of no affirmative evidence to rule it in.

My bet today is that there are certainly multiple software problems, both in Samsung's implementation and in the low-level drivers, particularly Broadcom's driver. It is established that Broadcom is working on a new one.

I suppose that, theoretically, the relatively new Broadcom chip or the Samsung circuits could be flawed. But the most plausible hardware risk, as you mention, is more simple -- that the internal antenna is just not sensitive enough. That would probably appear as an aggravating factor, but not the root cause of the complex set of symptoms we now see. If there are hardware problems, they probably are masked by the FUBAR software today.

Perhaps we can judge when the firmware is fixed. Once new firmware is rolled out, the hardware situation should be more apparent. I guess that makes me cautiously optimistic.
[Galaxy S I9000 General] kcharng:
I notice an antenna port at the back of my galaxy. Not sure if it is for a GPS antenna. But if it is, wouldn't it be easy for someone to design a new back case with GPS antenna buildin? That would be wicked!
[Galaxy S I9000 General] appelflap:
Oops, nobody thought of that yet :) Brilliant
[Galaxy S I9000 General] boomerbubba:
Reportedly it is for a GPS antenna. It may make sense for a car kit, to enhance the performance and make the phone, with the right software, function more like a dedicated sat nav unit. I've seen similar kits for iPhones.

But sat nav apps are just a subset of the GPS potential of the Android, which is designed primarily to be carried flexibly in one's hand or pocket. I have no interest in wearing an antenna on my head.
