LOL.... why you morons do that???

When I post my next video showing Motonav stoping navigation the SECOND car goes inside a tunnel, what your moronic explanation will be??

Where are your videos? Where your gps experience comes from? Wikipedia?

Heuristics? Rerouting? It doesnt reroute nor continues , you moron! It just position car back further in the route some seconds after gps signal is restored by the receiver or even longer depending on the conditions

Let me look for that tunnel

It wont have more air than an air-headed moron like you...get a life
[Galaxy S I9000 General] Oletros:
Moron? you don't know a s**t about what A-GPS is as you showed in the conspiranoic thread about A-GPS, you don't know a s**t about what I have been using since 10 years ago.

Moron? My God, youd don't konw nothing about iGo, navigon, Tom tom and how they continue tracking in temporal losing of locks.

Moron? BS
[Galaxy S I9000 General] andrewluecke:
I hate to join the war, but I agree with Oletros. ALL car navigation apps use snapping and hence heuristics.

If I tell you where I am, the current time, and how fast we are going, then proceed to block your eyes for a minute, and unblock them, anyone wise would follow the road forward on the map based on time difference and speed, and start working again from there.

There might be a timeout between when the GPS gives up and stops making assumptions, but any wise developer would make that assumption.
[Galaxy S I9000 General] Oletros:
And some programs use the acceloremeter sensor to track while there is no lock.
[Galaxy S I9000 General] Tyxerakias:
Tried it, doesn't work for me... nothing works for me :) Maybe the upgrade. How reliable are Clove in their intel, Beards?
[Galaxy S I9000 General] Bynar010:
Flashing the latest firmware and enabling skyhook has improved things for me, still not perfect tho, looking forward to the new firmware that's supposed to sort it out.....
[Galaxy S I9000 General] dakine:
I've now also tested Ndrive, nice app but same crappy results.

I'm still on JF3 firmware though, will try and flash my 2 phones tomorrow.
[Galaxy S I9000 General] Beards:
If you run GPS Refresh and wait until it starts to give readings then load say My Tracks and then jump back to GPS Refresh it should still be showing the updated readout... it does on mine.

How reliable ~ put it this way, I've known Chris Love and his Family for nigh on 20yrs. In that time I've got to know Chris quite well.

Chris is different to normal sellers in a number of ways, two of which are:-

1. He actually treats his customers not as a number on an invoice sheet but over time gets to know them personally.

2. When tasked to do something for the good of the community Chris and his team set off to find an answer.

An example would be with the HTC HD2 camera issue that had a 'pink spot' in the centre.

With the help of Clove I championed a crusade on HTC in getting someone to actually listen there was a problem.

I provided a mass of data collected from other users who had the problem and Chris used this when talking with the HTC representative who called on Clove.

Eventually a firmware fix was released.

There have been many other cases which I have brought to his attention (including this GPS issue) where in turn Clove have then approached the manufacturer to find out what was being done about it.

Clove have been keeping me updated on the GPS issue by email messages. They told me of a member we have here on the forum who sent his Galaxy S back to Clove for testing and kept me updated.

The said members Galaxy S was found to be defective, Samsung have been informed and the member has now a replacement which was given a thorough testing prior to dispatch to said member.

In a nutshell, I've no sales pitch with Clove but I can vouch for their integrity, honesty and caring professionalism. :)
[Galaxy S I9000 General] nadernick:
Tonight i had the chance to compare the gps performance of my i9000 to a desire. Result: the desire saw 11 to 13 sattelites, the i9000 only 6 to 7.the desire also locked on sattelites with a signal strength of 16. i9000 lowest lock ive seen so far was 22.
[Galaxy S I9000 General] piya_m:
After using it for a while, I have some observation points.

1. Even you turn A-GPS off in settings, Google maps and GPS Test still try to use wifi to lock GPS.

Even Wifi Switched to "OFF", they still can use it as small wifi icon appeared on status bar. So weird.

This mean some programs can bypass settings with ease. Software bug for sure.

2. If you try "Get Positon Test" in Lbstestmode (Secret GPS setting), it won't use wifi except Skyhook is set to ON.

3. If you can lock on GPS once, you can lock it again with ease even you've killed all process about GPS. I move to other area about 25km away, when I turn on GPS test, it can lock with ease without wifi or mobile data.

4. Skyhook on or off makes no different with my SGS. Still unstable as always. -*-
[Galaxy S I9000 General] molgen90:
I found the cold start mode to allow gps to connect, though it only seemed to work after a reboot
[Galaxy S I9000 General] Beards:
I found the 'Cold Start' to not update my position at all and the blue error window that My Tracks shows was always a medium sized window.

The second I changed it back to 'Hot Start' My Tracks updated my position and the blue error circle was smaller than the orange compass position.

In other words, using Hot Start it was bang on.
[Galaxy S I9000 General] Itsme87:
Got my reply from Samsung. Seams like they're working with the problem:

---------------------------------------------------

Hei

Takk for din E-mail til Samsung Electronics Nordic.

We have escalated the case and will return as soon as possible to you.

[Galaxy S I9000 General] Bynar010:
Its already been acknowledged on various forums that samsung are aware and will be releasing an updated firmware in the next week or so. Keep your fingers crossed.
[Galaxy S I9000 General] molgen90:
Ah ok, I'll try going back to hot see how it goes for myself after switching. New to forums as well :)
[Galaxy S I9000 General] Beards:
And we wish you well. :)
[Galaxy S I9000 General] Beards:
As it's nearing the end of the week I contacted Clove to find out what the latest was on the J6 firmware.

This is the reply I received:-

Mike

We haven't been informed of any delays with the update, but an email has been sent to the appropriate person at Samsung to check that it is on schedule.

[Galaxy S I9000 General] TravUK:
Thanks for keeping on top of this. The Koreans have had two updates now, and we're still waiting patiently :rolleyes:
[Galaxy S I9000 General] Tyxerakias:
I have just tried the best solution so far (for me), playing with the secgps.conf file in the phone. You need root for it, but it seems to make a big difference. Still the gps accuracy is bad, and once in a while you seem to be thrown at the other end of the road, but the signal stays on. It doesn't drop it like it did every second before I tried this. This is very encouraging while waiting for the new firmware, since every new test just points to a software problem...
[Galaxy S I9000 General] Robin.B:
It's incredible how much of a mixed bag the results seem to be, if there were more votes, it almost seems like they would all average out at an equal number of votes. I'm inclined to think that perhaps everyone's perception of a good GPS lock/signal is different depending on what phone they upgraded from etc. For me, GPS seems 3x better since JG5.
[Galaxy S I9000 General] Tyxerakias:
Robin, if you have rooted your phone, could you, pretty please with sugar on top, paste the contents of /data/gps/secgps.conf ?
[Galaxy S I9000 General] Bynar010:
I thought mine was better...until I drove into town and it just shat its pants and had no idea where it was. I can't fault this phone otherwise, but if its not fixed in a firmware Update soon its going back.
[Galaxy S I9000 General] dakine:
Beards do you know what Samsung actually told them? Were they given an actual time frame or are they just guessing?
[Galaxy S I9000 General] Beards:
Well.... they were told to 'expect' it by the end of the week. So at that it would be fair for everyone to believe this is what the actually meant.

I know Clove re-contacted them again on Friday to get an update. I'll be contacting Clove again on Monday to see if they received a reply.
[Galaxy S I9000 General] ehe12:
here I got my second replacement from Orange. Comes with orange official rom 2.1,JF3. also got a sim lock,wierd cause the previous 2 phones have no simlock at all. but that's not a problem, got it unlocked within 2 minutes.

just tested it by windows using GPS TEST, where previous 2 phones can get a fix within 2 minutes. Took more than 5 minutes still can't get a fix. I'm going to ASDA to do some shopping in 20 minutes. Will report if it can get fix outdoor and if the navigation accuracy and drifting are solved.
[Galaxy S I9000 General] ehe12:
i'm back! here is some comment on the new replacement. i used google maps to navigate to nearest ASDA. during the first 5 minutes it's doing alright and I was happy. After then it started drifting again and I was shown on a different road far away. Google maps started rerouting and then tracked me on the same road again and came back, took around 2 minutes for it to get normal. So...Problem still exists! Will call Orange again tonight and ask for a solution. Either exchange a different phone or cancel the contract, or simply get me a new phone in perfect working order...

funny thing is that when I mentioned manufacturing date might affect this GPS problem, the orange staff chose to ignore what I said.

such a pain in the ars...never expected such crappy GPS performance on such a shiny phone...
[Galaxy S I9000 General] EarlZ:
Its a hardware issue, what do yo expect ?
[Galaxy S I9000 General] ehe12:
Well I expect it wouldn't occur on all GALAXY S, I expect my replacement wouldn't have the issue cause there are quite a lot of people claiming their GPS are good.
[Galaxy S I9000 General] darkoroje:
I think it is a hardware issue but not in the sense that GPS is outright broken instead its performance is marginal and very sensitive to external factors. For example if it is affected by the radio noise from the 3g transmitter the GPS performance would depend on the strength of the 3g signal in the area. In weaker 3G areas the phone transmits using more power thereby creating more RF noise and impacting the GPS more. This would explain the fact that identical phones work better for some people than others and why Samsung is finding it so hard to fix the GPS.
[Galaxy S I9000 General] ehe12:
I'm gonna ask the same question again: any way to fix this hardware issue?

If not I definitely will send it back and exchange a different phone.
[Galaxy S I9000 General] TNStrangelove:
Can you do that on contract? I'm beginning to think I would like to as well, when I got the phone I was under the impression that it was a software fault that would be fixed. I'm kinda bummed out that it might not be fixable.
[Galaxy S I9000 General] ehe12:
I don't know yet but I'll find out. They charged me 90 pounds for the phone, at least it's not totally on contract.
[Galaxy S I9000 General] darkoroje:
If my assumption is right and it is hardware problem then there is probably no fix. The best that Samsung can do is work around it with software as they are trying to do.

I would like to stress that the hardware problem has not been confirmed and is just an assumption - I may be wrong. It would be helpful if Samsung would come clean and tell us what they are doing about GPS.
[Galaxy S I9000 General] ehe12:
Only if you can contact the technicians and they are telling the truth. I think it's too hard. I will just assume it's not fixable and return it. Technicians from Orange are welcome to test it and I think this GPS will let them down. They have no excuse to refuse because it's really a problem for me. including the original one, GPS on all 3 Galaxy S I have don't work properly. Guess the conclusion is fair and easy. I will have to make a call to return and exchange the phone...
[Galaxy S I9000 General] TNStrangelove:
Let us know how it goes, I don't think I'm at that stage just yet, but I might be soon.

Edit: Also what network are you with?
[Galaxy S I9000 General] ehe12:
I'm on Orange. this has been the third year.
[Galaxy S I9000 General] sanktnelson:
So did anyone test with official Froyo?

So I'm curious, now that the official Froyo update is out: Is it the magical GPS fix it was originally promised to be? I think I know the answer, but I'd still like to hear that I was correct in returning the phone...
[Galaxy S I9000 General] crabjoe:
I've been following the GPS posts since Froyo and it's still the same deal. Some say Froyo works better and others still say it's crap. I'd say you did the right thing.

BTW, I'm now pretty sure the issue is a hardware antenna issue. I say this because both the GSM and CDMA Galaxy S variants all have a high probability of the GPS not functioning correctly. If it wasn't the antenna, what else can it be since they use different GPS chips, drivers and software? I think the only thing in common, related to GPS, between the GSM and CDMA phones is the GPS antenna. Bad GPS antenna or bad antenna placement = bad GPS signal.
[Galaxy S I9000 General] ehe12:
The second replacement I got is now working,after I update 2.2 JPO. still got a bit accuracy problem, but it's now becoming quite acceptable. Get a fix within 30 secs, doesn't lose signal. Accuracy is still low, sometimes causes drifting problem. But in all quite all right.
[Galaxy S I9000 General] Oletros:
No, it isn't

.......
[Galaxy S I9000 General] NagyBaj:
My GPS is now reasonably good after the JP0 update in terms of lock-time and accuracy, however, my GPS turns itself off every 10-15min now and it's really annoying.

It's still on according to the notification bar, so I have to turn it off then back on again to get it working.

Has anyone come across this before?

Any solutions out there?

thx
[Galaxy S I9000 General] Frostfree:
Works reasonable well for me :)
[Galaxy S I9000 General] Wesleylau:
Mine works really well, got it from CPW UK.

Why people testing the gps indoor? Also using online map software google map to test the navigation is not a good ideal, because losing the 3G signal during navigation may harm the accuracy.
[Galaxy S I9000 General] stan28:
Yeah. Should be testing it outdoor. However, using Google Map to test the accuracy is acceptable (with good 3G signal). I used to have the HTC Vogue, and GPS on that device is always spot on. Google Map is definately not flaw.

Anyways, the real test should be:-

- Does not lose track of satellite while driving

- Accuracy within 10m

Not how fast is should lock on to the satellites.
[Galaxy S I9000 General] andrewluecke:
I somewhat agree, but the other things that should be considered are:

1) The accuracy bubble is correct (otherwise that can cause problems)

2) That Fitness/car navigation purposes are different. Many people don't seem to be acknowledging that Car navigation apps can accept quite major errors before doing minor weird stuff. For most, I agree the range of errors (with Trackerbooster at least) isn't so great that it is unusable for car navigation, but to me, it's certainly a downgrade from my forerunner for fitness.
[Galaxy S I9000 General] DamianGto:
Well i use copilot and it spot on.

If you look at this picture:

Here you can se me driving at 25 km/h and i have all satellite locked thats in view.

You can also se my signal strength is very good.

It also have the accuracy on 5 meters.

I don't know how i would get this better.

With my iphone i don't get this reading at all. In the city center it stop working, but the sgs is still spot on.

I think this is strenge that i got so good result on my sgs when i hear many complain about this.

If it was a hardware fault then why don't i have it?

My girlfriend have also an sgs and that works the same way.

So are we very very lucky or it something else?

[Galaxy S I9000 General] mauro_s:
Very good. But it worked so well also before the last firmware update ?
[Galaxy S I9000 General] maesebit:
On the time I've been testing the GPS I've realized that when I'm in residential areas, or places with no high buildings around, I get about 10-11 satellites with good signal, and they keep fix while moving. In this sitution Google Maps works great and it's spot on. 5 meters error.

However, when I'm sourrounded with tall buildings I get about 6 to 8 satellites with quite lower signal and they keep losing fix again and again. In this situation I never have less than 4 satellites fix at the same time, but I guess that's enough to cause accuracy proplems. Google maps starts pointing me everywhere and I get accuracy between 10 and 50 meters, changing all the time.

No software fix or firmware version is been unable to change this. My theory is, maybe some of them achieve a faster satellite lock, so when you move and lose the fix with one or more satellites, it recovers it quicker, so the impact in accuracy is smaller.

This could explain, aside from different real performance between devices, why different people is reporting such different results with the phone's GPS.

Just my assumption.
[Galaxy S I9000 General] andrewluecke:
Unfortunately, the accuracy bubble isn't always right. If you jump into My Tracks, stand in the same position for a while, you'll notice the accuracy bubble doesn't always enclose your location. And here's a photo which proves the accuracy bubble is inaccurate (I took a few more today too, but I'll only pull them out as required). Whether indoors or out, it proves watching the accuracy value for 20mins is pointless if you don't actually know where the GPS THINKS you are. How do you know that the GPS isn't telling apps you are 5km away from your actual location whilst in GPS status?

Also, remember that Copilot and other car navigation apps don't follow your position exactly, but rather do a large amount of processing (you'll notice even when on your driveway for instance, you'll be told you are on your local road, because it snaps you to the current locations closest road).

Similar to yourself, I do suspect that 3rd party apps might be slightly better for car navigation (as once I was on the freeway, and Google Nav moved me to a disconnected road once, suggesting that the algorithms aren't as optimal as they should be). However, before assuming Damian and his GF has perfect GPS, remember that he DOES say his tracks on My Tracks are dodgy, but My Tracks is buggy, and has never actually posted any tracks. Until he can demonstrate that his raw GPS is actually doing correct positioning, we shouldn't get too excited.. I think my picture is enough to prove that the accuracy value is unusable as evidence..
[Galaxy S I9000 General] DamianGto:
Andrew. Just stop posting same stuff time after time in every tread that the gps is.

Try for ones to understand that my gps works very good. I don't care ware my track think im driving when all real gps program is spot on.

I also don't stand still 20 minutes to se where im at.

[Galaxy S I9000 General] zorxd:
GPS lock means nothing. You can get 10 satellites indoor and a reported 5m accuracy but if you record your track you will sometimes see huge errors (500m) when looking at the track on google maps.
[Galaxy S I9000 General] Yeria:
Doesn't that mean then this is more of Google maps and SGS compatibility issue than SGS issue? My GPS works mostly fine until I drive through Toronto downtown.
[Galaxy S I9000 General] darkoroje:
No, there is nothing wrong with Google maps. The problem is GPS is the SGS.
[Galaxy S I9000 General] zorxd:
Why would it be a problem with google maps (and "my tracks" and google navigation)? It works fine on every other android phone out there.
[Galaxy S I9000 General] Yeria:
I never said there is a problem with Google maps. It doesn't matter if it works fine with every phone out there, because SGS can be the stand out phone that doesn't want to play nice with maps.

If the phone reads GPS properly, but doesn't show them properly on Google maps or navigation, there has to be something going on between the two. If it is the phone issue, GPS shouldn't work for maps AND the test.
[Galaxy S I9000 General] zorxd:
Did you look at the GPS coordinates in GPS test and compare on a map to see if they are precise? Just because it says that the accuracy is 5m doesn't mean it's true...

I know you can get a quick fix, strong signal with 8-10 satellites with the Galaxy S. That doesn't stops me from getting inaccurate results from time to time.
[Galaxy S I9000 General] Oletros:
If Google Maps, Google Navigation and MyTracks work well with other phones and there is more programs that doesn't work weell with SGS (coPilot, GPS Status, etc) the one to blame is not Google.
[Galaxy S I9000 General] DamianGto:
I don't se why people always dislike all proof on working gps. If someone post a bad track or something else bad. nobody question that.

It always the people that have working Gps that's been question and blame they are wrong and they must post a Mytrack that must be 100% correct or they well called bad things.

To me it seams that people don't want to hear that the sgs can have a very good gps.

I use copilot and it always spot on.

It had never show me on other place and it always show me on the road i am on.

It no use to post anything here that is positive for the sgs.

[Galaxy S I9000 General] Oletros:
I don't see why you can't understand that we are not denying that some (perhaps almost all, peharps almost none) SGS GPS can work.
[Galaxy S I9000 General] zorxd:
We don't ask 100% correct. We ask that the track be on the good street at bare minimum. Just like it does on every other smartphone.

People have been telling me this for months. I lost so many time with this. I still can't trust my recordings when I go running because half of them are wrong. What I want to hear is the truth.

Good for you if you use it a lot and it works well. The problem is that so many people never use the GPS and when they do they open GPS test. The software tell them that the accuracy is 5m and tell those who have problems that they are idiots. GPS test means nothing! It works fine for me too. The tracking is also accurate most of the times. But if I use it for let say 30 minutes or more, there are good chances that there will be HUGE mistakes in the track. When driving that means that it will tell me to turn left when I shouldn't because it thinks that I am 2 streets off. I also bought a second Galaxy S and it had the same problem, and the Bell Canad tech support guy finally told me that this problem affect all phones.

An other problem is that some people have a problem with their GPS. Then they install GPS fix XYZ or custom ROM ABC. They go for a 5 minutes test outside. It works. Now they report on this forum that the GPS is officially fixed. Chances are that they will never use their GPS again or make extensive testings and if they do, they won't report here.

Nobody should be allowed to report a working Galaxy S GPS if they didn't test it for at least 2 weeks and a minimum of 10 tracks recordings of at least 30 minutes each on different days.
