Hmm, I did try and track myself on the bus this morning and it did seem to have a problem finding me - it kept flipping between near where I was and about halfway back home. Used it walking down the street and again it didn't seem to be very good at nailing where I was (HD2 seemed much better). I've enabled location via cell location as well as GPS, so I'll see if that makes much difference.
This doesn't sound too promising :/
I've been using my iPhone 3G to track my runs when I head out, and I assumed the Galaxy would do just as good (or better!) at it. Hopefully it's something they can fix with a software patch and not a hardware problem...

Did you get it from Expansys? I am trying to find out whether it is just a batch or it is a more generic issue.
I too am seeing poor performance with the GPS. Seems to be a hardware issue.
I did a test over the weekend comparing my Galaxy S with a friend's HTC Desire. Using one of the many GPS utilities the Desire was consistently seeing and locking more satellites when stood in an open area outside. When running Google maps and showing the current location I found that the "accuracy circle" (for want of a better description) was growing and shrinking several times a minute causing the map to zoom in and out.
I've also noticed that the compass is almost unusable and showing a much lower signal compared to the Desire. I did perform the figure of 8 calibration several times.

Nope, got mine from Handtec. Really hope it's just a software issue that can be easily solved! Also noticed that google homepage in browser keeps saying I'm in China?!
Think I've read somewhere that samsung galaxy (the first one + the spica) have a broken gps driver causing such issues...don't remember if it was in sportypal forums or for a similar application. Very sorry to hear it's not fixed.
Nope I tried out google navigation at the weekend and was really impressed by the accuracy, it made my old tom tom look really bad.
So can we say that GS favours google navigation?
Can anyone confirm that?
This is very worrying, GPS is important for me, I don't want to have another N97 on my hands... fingers crossed it's a software issue....

I've not noticed any problems in Google Navigation. It found me almost instantly, and was so accurate in terms of showing me where I was while driving that there was almost no perceivable lag.
Whatever people are seeing it very unlikely to be a hardware issue, most phones use GPS chips from only 1 or 2 suppliers, its much more likely something temporary like a driver issue.

TravUK, have you tried google maps - did you have any problems with it? (although I assume navigation would be using the same data to find you)

Yep, Maps works fine, including latitude. Also used Waze which took a little while to get a fix, but was also ok.
Well the journey home was much better! Probably helped that I was sitting by the window on the top deck of the bus, but I managed to get a much better fix, using both google maps and navigation. It wasn't like 100% accurate or anything, but certainly no worse than my hd2. Hardly got the large blue circle, but it did think I was in a field a few times, but that's to be expected. To note, didn't seem to make much difference whether I had both gps and cell data selected, or just gps.
My gps works perfect. Google maps finds it instantly and waze and speedometer apps work fine too. Localization is spot on. The gps even connects when I'm inside the house wich my Diamond never did.
I tested Navigon, which can be download from Market for a tryal period of 30 days now, and it working great on my Samsung i9000
it may be a firmware issue , everyone who is having problems should post the sw. version for comparision with others
Comparison of Galaxy GPS and iPhone 3G gps.
Hey everyone,
There's been some discussion regarding the "quality" of the GPS function in the Galaxy S, and after testing it out today, I sure hope it's a software bug or I'm going to be very disappointed.
This is my run as recorded by my iPhone 3G (with Fitnio): http://dl.dropbox.com/u/810054/samsung_fail/Picture%203.png
Now this is the same run as recorded by my Galaxy S (with RunKeeper): http://dl.dropbox.com/u/810054/samsung_fail/Picture%202.png
Take a wild guess which one actually reflects reality. Can anyone shed light on if the new "leaked" firmware fixes these problems?
They're all based on standard chipsets so its unlikely there's anything wrong with the GPS receiver itself. I hope it gets updated soon as it seems to be affecting a fair number of people.
I've yet to find a Compass app that works on my Omnia7. I don't know if it's the lack of a GPS signal (been trying it indoors) - my old Hero used to work fine with no GPS signal as does my Wife's iPhone.
Has anyone else found a Compass app that works on the Omnia7 without GPS signal? I'm wondering whether my phone is faulty or whether the phone just doesn't have the hardware to get a Compass reading without GPS.
Isn't there a diagnosis code to test this?
Ya, pretty much.
One in the test menu, Not sure it's working 100% tho when i checked, so maybe any apps running off it's readings might be wrong. *guessing*
I read that there isn't a Silverlight API for the compass yet, hence no apps.
*#0*# from the Diagnosis app takes you to the LCD Test screen where there is a Compass tile, which gives you a functioning compass

Makes sence, Call me silly, but which way up is best for the compass, Flat on phones back, Or Back of phone Facing away from me.
As i seem to get two diffrent readings and havn't got a "normal" compass to compare too.
Having the phone horizontal will give you the best results - if you just rotate your position, the needle should point in the same direction. I've tried it in two locations and it seems accurate enough

Note to self *test outdoors before saying anything again about compass *
Thanks for the *#0*# trick - works fine, so it's just the apps that don't work as is suggested above.
It seems like my compass is somewhat off. I've downloaded a compass app from the market and used its calibration function several times, but it still seems off. This appears to be somewhat problematic when using google maps 5.0 in compass mode as well, since the actual compass directions don't line up with the calibration of the phone.
What's the most accurate way to calibrate the compass? Is there an app, or some other way, to manually adjust the calibration if its off?
In what way does the compass seem off? I have no problems with the compass on my end.
in maps 5.0, is so OFF!
Tested actually a few hours ago, my compass was like 30 degrees off.

Like the previous poster said...using compass mode in Google Maps 5.0, the direction of the map is off compared to how I'm holding the phone (if that makes sense).
Omg I know what you guys mean in the new maps 5.0 the compass is showing for me that its pointing a couple of degrees to the right. So has anybody figured out how to fix it?
Make sure when you're checking the accuracy of the compass that you are not using it around something that would be causing interference, especially the MyTouch Car Dock that T-Mobile sells. For some reason, that thing causes major interference, and makes my compass think it's 90 degrees off.
... Ironic for a Car Dock designed to help the phone act as a GPS device.
As many others, I have updated to official Mango yesterday. And i was really surprised by compass - its accuracy is much worse than simply guessing "where the hell could that north be" . Do you experience the same?
Majority of applications I tried required "calibration" - shaking Omnia in 8 shaped movement, but I found this absolutely useless. Even if the pointer is in north-south orientation, it usualy swaps north and south part of the pointer.
I tried:
Compass 7 from Redtalon - points north in 1 from 10 cases, usualy points towards west. Rotating phone makes this absolutely crazy
123 Compass from Agulhas Solutions - sometimes points north, but pointer is shaking as hell, most usual direction is south-west. Rotating your phone means rotating pointer anywhere. No sign of pointing towards north...
Compass from KanzSoft - this one looks to be the most promising. It shows at least basic knowledge where to point, but is oscilating in +- 10°
Maybe I just found wrong applications - do you have any suggestions?
I totally agree...
It sucks and they didn't even implement it in bing maps, that's the only thing I miss from the iPhone.
I tried the first two compass apps and the first one was stuck at north until i shook my phone, the second is not better than the first...
Agreed. My compass is utterly useless.
The compass that is included in the diagnosis app by entering *#0*# works pretty well over here. It does oscillate quite a bit though...
If I understand well the Mango SDK docs, our crap compass doesn't manage to pass the calibration test made by the devs. Only the Compass app from KanzSoft seems to use results even if the sensor is not calibrated.
I'll try to play with the sample as soon as i find so time to.
As far as i'm concerned, I didn't even know that the Omnia7 came with a compass, so it's a good news.
well, not for me - for me, it does not do anything - diag version 0103

Hey.. Remarkable. I tried the app. I won't get passed the calibration. But in the background you see a compass and it's working quite well (best I've seen so far). So if Samsung just fixes this calibration issue, we could actually have a proper working compass on our Omnia7. They fixed a lot of issues in the Mango driver update package. I hope they're gonna fix this one too.
Heathcliff74
Optimus 7 too....
Something, somewhere is completely screwed
Through the engineering menu, compass works fine (a bit jumpy - but at least points to North!)
But...every compass app I've tried points the the wrong way, usually by 10-20 degress
Even the official Scansearch app is ropey - allthough it it does seem to get it right eventually after rotating the phone a few times
(often gets N/S flipped)
Mango RTM + latest firmware (1.0.13.10)
Confirm: mine pointing west too.
how to fix ?
Deleting and reinstalling the diagnosis app made mine run much better.
However, mine is 180 degrees inverted (i.e. North shows as South)....

That was a cheap shot haha...
It more for a stargazing app I use - Skymap... check it out its pretty good... it uses the compass and telemetry data to orientate the map on the screen so it knows where you are looking.
Try Compass VO, it's the most accurate one compare to my actual compass.
It looks like the compass on the Omnia 7 is off by 10* according to Compass VO accuracy fix.

edit: so, compass is confirm to be crap. Rotation is in consistent.
I used to have heading at least in diags, but no more. I've got only those XYZ values. However it doesn't change the fact that I never got trustworthy readout from compass. Sometimes it was correct heading, but I never knew that until I compared it to real compass. And when I turned 90 deg compass heading changed only little bit, like 20 to 40 deg or sometimes it didn't changed at all.
I have to say it's quite disappointing and I'm thinking about trying luck with RMA.
On my Focus, at first all compass apps didn't worked correctly. After I read this diagnose menu, I tried to enter. The XYZ changed as I change my direction, but the compass didn't move at all.
Then I tried the compass app again (from Kantz something), It now pointing in a consistent direction and rotate (keep pointing in the north???) as I rotate my position.
Dunno what really happened here ...
Ok, this is my first post. But I hope this willl help some Omnia 7 owners.
I tried also a lot of compass Apps but without luck. There was no App which showed the correct cardinal direction. Then I read in another Forum someone had reinstalled the diagnostic tool and after that everything was fine. So I tried this also.
And...after the deinstallation of the diagnostic tool the 'My Compass' Apps works perfect. Now the app didn't ask again and again for reinitialization of the compass.
I didn't installed the samsung diagnose tool again and I didn't tried other compass apps but this was for me a first step.

Something else... Calibration!
From this article: http://blogs.microsoft.co.il/blogs/alex_golesh/archive/2011/05/24/windows-phone-mango-what-s-new-new-sensors-amp-tooling-enhancements-part-3-of-8.aspx
In addition, compass sensor enables application to subscribe to the Calibrate event, since magnetometer sensor which used to implement the compass is subject to external interference. Metal obstacles, high-voltage electrical installations and some electronic devices could interfere with Earth’s magnetic field and change the local magnetic field’s values. In case the sensor needs to be calibrated and the compass API fires the Calibrate event. When this event fired the application have to present the UI with instructions to perform sensor calibration. Sensor calibration performed by waving the device in figure 8 pattern.
The API doesn’t provide any “CalibrationComplete” notification, and it is up to developer to decide when data accuracy sufficient to the application. In general, HeadingAccuracy below 10-15 degrees should enough for most applications.

Most compass apps have a calibration function. I couldn't get this to work. Didn't matter how I moved the phone in a "figure 8". Then I tried Youtube and found this video: http://www.youtube.com/watch?v=sP3d00Hr14o. It's for an iPhone, but it works the same. The guy in the video wave just once to calibrate it. I had to do it a few times, but then the app said: Calibration complete!
I now finally have a working, calibrated compass in my Omnia 7!
That also means I can use all apps that need the Mango Motion-sensor. Omnia 7 doesn't have a gyro, but with compass and accelerometer combined you have a fully functional Motion-sensor (although slightly less accurate than newer devices that also have a gyro).

Actualy Compass VO works very well on my Omnia 7 .. once the phone digital compass is calibrated (8 shape) I have no issues with rotation, pointing magnetic and geographic north.
I like it because it allows you to set a map (topographic) in the background and use it together with compass to navigate. Not to mention multiple themes + other features ...
Really recomended.

Anyone else having issues with gps tracking and compass calibration?
Whenever I use maps or navigation, gps fails to track. Despite moving a number of kilometres, maps show me unmoved...then lurches forward only to stand still again. I've attempted to clear and update AGPS using the GPS Test app...but no luck.
Compass calibration seems to be an issue for a number of people. I have to recalibrate the compass after every restart. This recalibration has no effect on gps tracking.
I'm using the international version.

No, you'll still need to recalibrate. It's still unclear to me if this impacts all or only some units. I just know I have the issue.

But long story short, to recalibrate your GPS/Magnetic Sensor, you need to do the following:
Dial: *#0*# then under Sensor look at the Magnetic Sensor, should be a blue line with a "3" inside, if not, rotate your device along the 3-axis and it should be calibrated. Unfortunately it needs to be redone after every reboot.
If you could post if you have the Exynos or the SnapDragon it would narrow it down to who has this problem.
I am curious if this is all or just some units.
Even with the recalibration I'm not getting reliable GPS. It improves but still lurches every 30-40 seconds when driving.
I've got the Exynos version in Australia.

From what I've seen is that it's mostly the exynos versions that have this problem. After the recalibration, your gps should be all good and accurate.

The magnetic sensor has nothing, at all, to do with GPS location and navigation. GPS relies solely on satellite triangulation. (And ground transmitters for some things, but Android phones don't take advantage of that.)
GPS nav and location have been fine for me. What option do you have selected for location services? Long press on the location icon in quick settings to see. You might also try clearing cache and data for the Maps app, to see if that helps.

Magnetic Sensor definitely has something to do with the GPS, give it a try if you have an S7/S7E. The blue line once calibrated points to the north , that is under Sensor option, under #*0#*
Ive done my share of research on this subject as it was also a problem on the S6E I had previously to the S7E.

Sorry, but GPS location and navigation do NOT use the magnetic sensor. Period. Ever. The magnetic sensor can display a pretty blue line on the screen, but GPS relies on satellite triangulation. Period. Not a magnetic compass. Period. GPS couldn't care less where magnetic north is.

I know my GPS works far better once I've calibrated the magnetic sensor, coincidence? Maybe, maybe not, it's been the case since I've had my S6E and S7E, I have everything enabled under GPS and it wasn't accurate until the calibration

Technically, you are correct in that GPS systems do not use compass info. However, smartphones like Android and iPhone use secondary information to supplement and improve upon GPS accuracy. These include compass information and known WiFi and cell towers. Some use Bluetooth although the range is limited.

Well I decided to switch from the edge to the regular s7.
Compass still needs recalibrating on every restart, but GPS is back to normal. I think there was an issue with my s7 edge that contributed to the lurching, problematic GPS.
GPS still works properly without recalibrating the magnetic sensor...the arrow just points the wrong direction .
