now have aprox 6sec fix on 6 birds

in the open it goes to 11/12 bird fix.

walked a 10km round with "Maverick" normally it lost track couple of times

now it followed the route almost perfectly

I think I love you lol, i was getting so pi$$ed with this phone, I use gps pretty much daily for driving and my tracks for cycling and it has been total rubbish i was thinking of selling the phone (for this problem alone as everything else i find awesome), and this seems to have solved things (ive hardly tested but i have found that gps is really quick IF the gps symbol appears but it hardly ever does now with this setting it always appears)
[Galaxy S I9000 General] alovell83:
Thanks for that :D. There are a bunch of other options in here, do you recommend changing anything else for better GPS performance? Better battery life?
[Galaxy S I9000 General] Sloper59:
So is this a complete fix for the Galaxy S' GPS problems?

I'm waiting to pull the trigger on one of these phones but the GPS probs are holding me back. Galaxy S vs HTC Desire vs wait for the HTC Desire HD. Oh what to do..
[Galaxy S I9000 General] BackfireNL:
The only bad things i have experienced with this phone are:

- Camera has no flash

- Camera (video recording) has no image stabilizer

- Lag (fixed it with firmware WJG5 so don't have it anymore)

- GPS (but i haven't tested it extensively)

The rest is superb!
[Galaxy S I9000 General] voodoochild2008:
never really had gps problem but I went into that menu and found a setting called skyhook...it was off so I turned it on, right thing to do or off for a reason?
[Galaxy S I9000 General] Tyxerakias:
So, no news I take it? I understand now why everyone is so against Samsung's customer service. :(
[Galaxy S I9000 General] Beards:
I sent off another quick message to Clove this morning and their reply was they had already sent another request themselves only half-an-hour earlier to my request....

[Galaxy S I9000 General] yuszairi:
Telstra (Aussie) and HTC are working on a GPS fix for their Desire which also runs android 2.1....

is it android 2.1 problem or specific to our SGS??
[Galaxy S I9000 General] TravUK:
A lot of what we see works fine on other 2.1 devices and is very specific to the Galaxy S. But the GS is one of the first devices to use the new BT3/GPS/FM chipsets so its not suprising there's a few bugs to iron out.
[Galaxy S I9000 General] dakine:

[Galaxy S I9000 General] badmrfrosty:
GPS and overheating

I know there are serveral posts already about problems with the GPS on the phone but my issue is slightly different. That said, I do have the same problems with accuracy and loosing signal that are reported elsewhere.

For a test, I took a 1 hour trip across Prague, I knew the route and which roads I was on by heart. During that trip, my position was lost on about 10 seperate occassions. More worrying was my position was reported completely wrong maybe 5 or 6 times, meaning the directions I was getting were totally inacurate and would have me driving in circles.

The other problem I had which I have not seen reported here is that when I turn on GPS and use co-pilot the phone gets HOT HOT HOT and the battery drains at an alarming rate. Granted it was a very hot day but I had AC on and the phone was not in direct sunlight. I lost maybe 50% charge while on my hour long drive. No problem I thought, plugged in my car charger only to be warned that the battery was too hot to charge. What the hell? If I cant use it to navigate while charging, driving more than 2 hours will not be possible and driving under 2 hours will most likely mean I arrive with a dead battery and a phone that is too hot to charge.

So not only is my GPS useless to the point of being comical, it also eats so much battery and becomes too hot to charge. Anyone else experience the same heat issues?
[Galaxy S I9000 General] dakine:
Yes i've noticed the alarming battery drain while using gps software, i didn't notice it gets so hot that it won't charge though.

Did you try other gps software? I've tried several and so far I like ndrive the best for it's simplicity and speed, it's just too bad they don't have live traffic for most of europe.

I really hope that the problem is related to copilot because if not it would just add one more serious problem to the sgs.
[Galaxy S I9000 General] navmanyeah:
High battery drain while using GPS is perfectly normal. It will happen on any device, even dedicated GPS. However, your battery getting so hot that a warning pops up, now that's something new. Are you sure its wasn't in direct sunlight?
[Galaxy S I9000 General] badmrfrosty:
Thanks guys, I am sure the phone was not in direct sunlight but I will try another test during the evening and with different software to see if that improves the heat issue.
[Galaxy S I9000 General] Pika007:
I already did a 2 hour drive with GPS, yeah, the device got warm, but not HOT as you describe, plus i didn't get a warning of any sort...

As the other folks said, watch out for sunlight.

Sunlight under glass+black device= HOT HOT HOT.

GPS now working

I sent my SGS back to orange as faulty due to the GPS issue and now have another - which still runs JF3 but has so far been spot on for GPS lock performance. Now the weather has improved slightly in the North of England, so it could be that, but I'm not sure..

It sort of implies that it's not just a firmware issue..
[Galaxy S I9000 General] TravUK:
The GPS can work fine for several days in a row, without a hitch, and then be useless for several more days, for others its rubbish the whole time.

Nearly 2/3rds of owners are reporting some issue with GPS and your new phone is unlikely to be any different than the old one.

However, its good that people are returning phones, as returns more than anything cause the people at the top to sit up and take note.
[Galaxy S I9000 General] Tyxerakias:
I finally got an answer from Samsung customer support about my GPS problems.

They sent me a long email explaining how to use Google maps. :mad:

And the last sentence says:

'However the new firmware for the Galaxy S handset will be released soon.'

Needless to say I sent back a 'not satisfied' rating.

Argh.

Yes, I submitted a very detailed log of the GPS issues and even identified myself by my profession, namely a microprocessor architect and driver developer for many of their products. Sadly I also got the how to use Google Maps response. I gave them top marks and thanked them for fixing my problems :rolleyes:

**** this, I just sent in a tip to Engadget and Gizmodo. Who else should I send a tip to? BGR?

I'm hoping that this story gets exposure on some of the big tech sites, so that Samsung will actually respond to/acknowledge the issue, and tell us weather a firmware upgrade will fix the issue.

I suggest that everyone else also send in tips to Engadget/Gizmodo
[Galaxy S I9000 General] Itsme87:
Sent them an email a week ago aswell. If many people contact them maybe they'll make a story about it :rolleyes:
[Galaxy S I9000 General] TravUK:
I also tipped em last week.

EDIT: I've just tipped them again with the following message and links:

Hi,

Can we please have engadget take up the banner for us poor galaxy S users. With over 1 million Galaxy S phones now sold, there's a lot of people wandering around not knowing where they are as their GPS doesn't work.

Thank you.

As far as it goes this problem has spread all over europe, I found forum threads talking of this problem in english (of course), french, german, and spanish so far.

Sorry I can't post the links as I'm a new user and not authorized to post outside links (spam prevention or whatever).

I can send them to whoever is interested by private message though.
[Galaxy S I9000 General] Rawat:
XD, seems like I tipped them with something very similar :D

There seem to be many reports over on XDA, and on other forums complaining about very bad GPS performance from the Samsung Galaxy S. I myself have the galaxy S, and compared it to a friends Nexus One, running stock 2.2. His phone got a GPS signal within seconds, while my phone took near to five minutes to find a lock, and wouldn't keep track of our movement within the car. After it finally locked, it wouldn't update at all. This was in London, UK.

I hope that by giving this issue some exposure, you can get Samsung to comment on the issue. Is it a firmware issue? Is it a hardware issue? If there is no fix, this phone is going back to Vodafone :(

[Galaxy S I9000 General] Oooch:
So is there a definite solution for dead GPS after flashing?

Ever since I went to JG5 my GPS hasn't worked, it did for a bit but then it stopped and I'm not sure why.

I've messed with the gps.conf, that didn't work.

I've changed skyhook on and off, neither work.

Forcing the phone to just use GPS without wifi didn't work, I'm on SamSet 1.2C now and still no GPS even though others said it fixed it for them.

I also changed the network options to something different too so it basically didn't connect to the higher phone speeds unless it had a good signal? That option.

But basically has anyone nailed down any solid information? Thus far it appears that certain things work for some people and certain things work for others. :confused:
[Galaxy S I9000 General] Intratech:
You need to go into settings and turn it off and on again. For some reason JG5 does this and everytime I reboot the phone I have to do this for GPS to come on.
[Galaxy S I9000 General] Oooch:
Lol that worked, thanks a lot.
[Galaxy S I9000 General] dizzle118:
Spotted this http://phandroid.com/2010/07/21/easy-fix-for-t-mobiles-samsung-vibrant-gps-issues/

reported as not working on the Galaxy S though..... perhaps someone could suggest other settings as whats in the blog maybe incorrect for the Galaxy?
[Galaxy S I9000 General] TravUK:
I'm losing track of how many wonder fixes I've seen. The key thing with pretty much all these 'fixes' is that people reset the GPS driver as part of the changes, and after a reset is when the driver works best. They confuse a reset, and temporarily working driver with a genuine fix.
[Galaxy S I9000 General] sjdean:
Yes, my new phone is also playing up now. Still not as bad as the last one, but very hit and miss and losing connectivity in all sorts of situations.

Heat seems to be the biggest culprit.

I don't belive the Sky Hook fix, as this is merely an alternative A-GPS - which when you lose GPS signal, you will go bouncing off somewhere else. None of the other settings I've tried has helped, and I've tried them all.
[Galaxy S I9000 General] TravUK:
Indeed most of these 'fixes' just change servers or other a-gps related config, which have nothing to do with signal strength and tracking.

The other one I see lots of, is people assuming clouds have a negative impact on signal strength, when they have almost no bearing on it, besides, which is more conductive, water or air? (That's a joke, in case any of my antenna colleagues are reading this) :)
[Galaxy S I9000 General] appelflap:
oeps, deleted
[Galaxy S I9000 General] TravUK:
As I work for a major supplier of GPS chipsets, the very nature of my job prevents me from revealing anything that isn't already in the public domain. I don't claim to be an expert, but I am a microprocessor architect and driver developer by profession, so do have some experience in these matters.
[Galaxy S I9000 General] dakine:
I'm pretty positive that the fix will come. @TravUk: if the gps can see the birds then why couldn't they just program the driver to lock more satellites and to hold them at lower snr's? Is that something that could be hardware limited? Doesn't seem logical to me, isn't it tracking the unlocked satellites anyway?
[Galaxy S I9000 General] TravUK:
It's just a guess, but I suspect its a really embarrassing bug in the software. Like a static array of 8 elements with a note next to it that says /* Replace with dynamic allocation before release */ :D

I really don't know the cause, but as the driver tracks more than 8 there's no obvious reason why it shouldn't lock to more than 8.
[Galaxy S I9000 General] Beards:
It appears we are not the only one's being ignored by Samsung......

Clove's latest attempt at getting the representative to come forth is proving a little pointless at the moment:-

Mike

We understand your concerns and have been attempting to clarify the release date of the update and how it will be implemented it with our Samsung representative. This information has however not been yet been provided to us, but when it is available it will be immediately forwarded it on to you.

[Galaxy S I9000 General] appelflap:
Just did a couple of experiments indoor after upgrading to JM1 yesterday evening. On all occasions that I did a gps test I saw satellites inside my house and even had a fix on one occasion. Now, this doesn't mean anything about real life performance of course. On the other hand, it is pretty remarkable. I never saw satellites on the galaxy indoor in the location i tested, neither did I saw them on any other phone I own/owned. Other users who didn't saw any satellites inside before with the galaxy also reported indoor reception on some quick experiments after upgrading yesterday.
[Galaxy S I9000 General] michael0702:
I can also add that I have been running gps test for over a hour driving around in my car. I always have 10-11 gps fixes.
[Galaxy S I9000 General] Beards:
Then this is not the latest from Samsung themselves.
[Galaxy S I9000 General] dakine:
I see reports from JM1 users that gps reception has improved, can anyone confirm?
[Galaxy S I9000 General] appelflap:
Popper made a very good point when he noted that one should look for falsifications instead of confirmations when one is looking for the reliability of a statement... Confirmations are very easy to find (look at the pseudo-science)
[Galaxy S I9000 General] ed10000:
10-11 in use?! Or do you mean 10-11 in view? Coz mine has NEVER locked onto more than 8 at a time, no matter how many are in view. I also remember reading somewhere that the SGS's GPS chip is hardware-capable of locking onto only 8 satellites at once.

Has anyone else seen it lock onto 8+ satellites? If yes, could someone post a GPS Test screenshot if it isn't too much trouble?
[Galaxy S I9000 General] dakine:
It seems that those who claim great results don't know the difference between a visible satellite and a locked one. They also don't seem to realize that 30m accuracy is crap.

I wonder if its taking so long because the part is not made by Samsung.
[Galaxy S I9000 General] appelflap:
Weird hobby you guys have.

I for one realize that 30 m is crap. I abusively posted some picks from a test with a accuracy of 30 m.. and ppl were all over me saying that i'm an idiot :D Well i'm not. :p Tests shows a 5m accuracy most of the time, with a occasionly fall back to a 10 m acc.
[Galaxy S I9000 General] Beards:
Actually the chip is Samsungs latest combined chip.

JM1 F/W Update - Some Improvement

After upgrading to JM1 last night and doing some tests -

It still cannot lock onto Sats <=20 snr

It still looses all Sats randomly

It still shows large blue circles when locked onto a 3-4 Sats

It has improved in the number of Sats it can see however this mean nothing if it cannot lock on and give you accurate location. I was getting 32 feet to 96 feet most of the time.

I love this phone, have had the iPhone 3gs/HD2/Desire and this is the best in my opinion. SAMSUNG TECHIES IF YOUR READING THESE FORUMS - GET IT SORTED.

CONCLUSION - JM1 does not fix the GPS Issue :(
[Galaxy S I9000 General] navmanyeah:
OK I am sad to say, I now join the ranks of those who cannot get a lock on GPS. After owning the phone for 2 weeks and having the GPS work brilliantly (I'd get a lock within seconds), now it even refuses to find any satellites.

Now I'm not sure exactly when it stopped working but it has to be within the last 48 hours or so. I haven't flashed any ROMS (still on original DTJF3), I rooted but that was over a week ago and the GPS was still working brilliantly after that. The only thing I can think of is that my friend went crazy with a game yesterday and the phone got quite warm. Could this have fried the GPS chip somehow?

I also tried to change the gps.conf file as per the other thread yesterday, however ASTRO didn't actually save the file and it's still says north-america.pool.ntp.org (i live in Australia). I don't believe this affected anything, so I'm ruling this out as a culprit.

I'll do a bit more troubleshooting and see if I can find a solution.

EDIT: Well that was quick. Seems like all I had to do was go into settings > location and security, disable USE GPS SATELLITES, wait about 30 seconds, enable it again, and now my GPS works! It sounds too simple to be true for you guys though.
[Galaxy S I9000 General] dakine:
@ navman

Yeah it looks like the driver hangs or something. I put a gps on/of switch on my home screen for those occasions.
[Galaxy S I9000 General] cavinsoo:
Followed the steps provided here (Samsung Galaxy S I9000 > Galaxy S I9000 Android Development > Still got GPS issues? Try this.) Sorry. I can't insert link here. This forum limits me from doing so.

No thorough testing yet. I just went outside my house and GPS works almost instantly. I used to get 8 satellites in view but now I have 11. I'm surprised.

I'll go for a drive tomorrow.

DTJF3

Settings > Location and security > Use wireless networks (unchecked)

Settings > Location and security > Use GPS satellites (checked)
[Galaxy S I9000 General] Pika007:
You still get 8 sattelites.

Only the coloured ones are the ones you have a lock on.

Although i have to say, if the device holds a 5m accuracy lock for the entire navigation, i don't really care about sattelites and whatnot.

GPS Problems with XWJG5

I joined the ranks and flashed my phone with XWJG5. Nearly had kittens after it said it was going to Set the PIT file and Do Not Turn Off the phone, Odin just sat there doing nothing.

No problem, I read all about this... battery out of the phone, back in... power on... hmmm... looks dead.

Thankfully Odin worked next time.

Anyhow, the first day, the GPS looks a lot more stable, but it still has serious reception issues in not using anything less than 20 Snr which could be difficult when you're going past a building and the only satellites above and behind are < 20 SnR.

Plus the GPS driver now seems to buffer the changes, a fresh install of MyTracks now doesn't show zig zag lines, but gives sweeping corners if I turn 90 degree right while the GPS takes a bit of time to lock on.

Might root the phone and edit the gps.conf file....

What problems do you guys see on XWJG5 with the GPS?

Cya

simon
[Galaxy S I9000 General] larryccf:
what GPS test program are you guys using that gives you that graphic representation?

after 4 days of responsive and accurate GPS, last nite on the way to dinner (clear skies) the GPS was acting wonky.....

tks in advance
[Galaxy S I9000 General] badmrfrosty:
Just upgraded to the newly released JM2 firmware.

Short GPS test done. Tests were done on a fresh install of JM2, no GPS settings were changed. All data connections where disabled at the time of tests. Tests were done on a cloady day in the center of Prague, CZ. I ran GPS Test while stationary for about 15 mins.

- Max satellites seen: 10 - Average: 8

- Max satellites locked: 8 - Average: 5

- Best accuracy: 5M (16 feet) - Average: 5 - 10 M

- Max SNR of locked satellite 42 - Average: 36

- Signal jumped around a little but lock was completely lost only once.

- Never saw a lock to a satellite with a SNR of less than 20

Overall it is a improvement for me, before the update I would get a decent enough position but would loose lock to all satellites every 30 secs or so. Still a little worrying that I never saw a lock onto more than 8 satellites at the same time.

Step in the right direction, will try a drive test later.
