I notice that when using the JK4 modem my compass always points SW. I'd prefer not to change modems as JK4 seems to give me the best phone and GPS reception. Anyone know of a way to fix this?
Have you tried waving it in a figure 8 in front of you? This is allegedly how you're supposed to calibrate it and it does seem to work.

indeed i have. ive read that the app "GPS Test" has a tool built in for calibrating the compass, but i cant seem to find it.

GPS status app has the calibrate compass ability. I haven't seen the option in GPS test.

just tried that and had no luck, unfortunately. am i correct in thinking that it is just something weird with this modem?
I've found that just like a magnetic compass, being near large metallic objects (like a car), or near electronics (like computers or fluorescent lights) can sometimes affect the compass in my cappy.

I've read complaints of GPS and G-Sensors being out of whack, but didn't see anything on forum about compass calibration.
I noticed on my i9000 yesterday that while tracking myself on Google maps, that the compass should me pointing about 20 degrees to the right of the direction I was actually driving. In aviation, we call that crabbing, and it's normal based on wind, but not in a car.
I turned the direction my phone was pointing and the heading on the vehicle in the map started tracking properly. I guess my phone needs a little compass calibration.
Any idea where to this from? I'll dig around in the debug settings when I get some time, but hoping others might have found it already.
Thanks.
there are some free compass apps on android market that will display an actuall compass on your screen - and those will have a calibration tool you use when setting the compass up
No need for a special command.
Just turn the device 180 degrees and backwards two or three times in any program which uses the compass and it will be calibrated.
I'm a pilot too and I actually purchased a magnetic compass for my car and noticed the same thing. Haven't tested the phone's compass in my car though.
Are you forgetting some planes have Compass Deviation Cards to compensate for errors caused by the aircraft itself perhaps? Remember, cars have a significant amount of electronics, and a magnet in the alternator that can affect the direction of the compass (the magnetic flux created by the car is actually what triggers traffic light changes, so it probably isn't miniscule).
Btw, not sure crabbing is the correct term here (normally crabbing is isolated to wind I think). Correct me if I'm wrong (I'm still PPL).
Not sure about google maps, but I have noticed my hardware GPS (Navman's and that other rubbish which will be collectors items soon) actually use track, rather than heading.

I have a galaxy s and so does my daughter we both have a compass app from android market installed on our phones , both phones will not display the correct direction i have also tried a friends galaxy and his is exactly the same .
I have a xperia X10 and that displays correct directions with the same compass installed so i can only assume it is the phone at fault , i love the phone but this is annoying and i wonder if it is related to the gps problems this phone appears to have ?.
good old fashioned magnetic compasses don't work in my car, regardless of where i install them
it will always point EAST, very annoying, good thing it doesn't affect my GPS or my SGS i've yet to test the compass mode inside the car.
As i've taken it for granted no compass will work inside my car, as it has speakers every where and metals all around.
before there was such thing as a GPS, i used to be a good old scout and used maps + compasses to find my ways when driving in unknown streets

No, you're correct about crabbing...it's the term I learned for landing with a cross-wind and yawing into the wind to maintain your track to the runway. It's just what came to mind looking at the vehicle indicator and the roadway, it looked like a plane landing on a runway and that's what popped to mind.
Thanks to everyone else about the compass app in the market, I'll check it out.
Probably best to grab a real compass and compare to your phones one.. Then you'll know for sure.
But for GPS apps, track makes more sense because especially whilst driving, the phone has no way of knowing if it is pointed towards the front of your car.
(Btw, for non-pilots, when I say track, I refer to the direction you are actually going, rather than where you are pointed towards).
I'm a electronic engineer, A compass actually show where the magnetic field is more effective as North (and South) but what does make the differ is electronic compasses are more sensetive and may effected by a little change in magnetic field (for example holding a little ironic screw around it) so it may show wrong direction based on your country (and sometimes region). so the manufactors calibrate it on an avarage in order to make it working all around the world. but if it is not satisfying go to a service center they calibrate it for you!
(if you're geeky one you can do it on service menu yourself but it takes time to do a good calibration!)

HI, mdh_heydari
ok, but how to calibrate? even if it is time consuming and difficult. What is the procedure in SGS I9000?

There are 2 ways, the best one is some little fixes in android kernel and the other one is making mods for famous navigation softwares like Google Maps.
Hi! I hope to be usefull.
When I see the arrow in the google maps the position is always the same. Its possible that the compass can be the cause of gps error?? Its possible turn off the compass to try the gps alone??
Best regards and sorry my english.
ive also wondered about this. the arrow in mytracks spins around like crazy while moving. if gps programs use the compass to help tell the direction then thats gonna be a problem.
Does anyone know if we can test this in some way? I would gladly try any solution or help with alpha testing.
gps - compass or ...sensors?
hello I have noticed a strange behavior of the gps too..
I have done many tests with the program "GPS Test" (available free on Android Market) and I noticed that after the fix if the galaxy is moved, especially if changes from portrait to landscape ( or vice versa), the program loses the fix with the satellites (all indices of satellites in use turn gray), it never happens if i disables the landscape mode in the galaxy's settings or in the gps-test 's menu...
Maybe I'm wrong, but I think the GPS is less sensitive for satellites but too sensitive to the position variations of the smartphone (horizontal / vertical during use) .. I do not know if it happens with all programs that use GPS, but I do not think this should happen.

Like earlier Garmin or Magellan gps, the compass should be used up to the point that the gps shows 5km/h (adjustable in some devices) because the signal of the gps is unstable and is not reliable for direction under that speed. Also...

... like in some sirfstarIII gps, the receiver (gps) was adjusted so that it didn't show any movement (and speed) within a circle of 15m or 30m (also adjustable) to avoid showing movement (and direction) while you were stopped.
Another fact in this category of gps devices (single frequency, autonomous etc) is that they are much more accurate about speed (0.1km/h) than position (typically usually 5m, sometimes 2m-15m or more)
So if we don't know what the default settings for the SGS's gps are, we don't know what could really be the problem. Or do we?
Anyone who knows more about the gps hardware used in SGS could help...
It would indeed be interesting to try to disable the compass altogether and see what the effect on GPS is.
Perhaps I'll look at this. I'm not a big GPS user myself so proper testing would definitely not be me.
I am using "Maverick" from the market and it seems to be working properly....
thnks about all. Im sure that someday we'll have a operative gps. Keep investigating.
Regards.
Maybe you can help me diagnosing this. My compass is calibrated, so it points to the north correctly, but it is not steady, it jumps around 20 degrees (10+, 10-). Already tried 8 pattern calibration and the ms3c_yamaha.cfg deletion, but it still jumping. There's nothing around to mess with magnetometer, it works like this even if I am in the middle of a grass field.
A video of my SGS running some compass applications:
http://www.youtube.com/watch?v=I8urdsB4V_w
How is your compass? It stays pointing north, solid as a rock, or it jumps a little, like mine?
Thanks
Probably you need calibration or recalibration...
Regards
nice design on the compass app
what modem do you use, maybe it's related (probably not^^) I'll try my compass later outside, I'm currently surrounded by computers and walls so It wouldn't be tooo accurate if I tested now I would imagine.
I will edit my feedback into this post^^
EDIT:
also jumps
Mine is working perfect
I have the same issue.
I noticed also that if I tilt the phone from a horizontal position, tilting the upper side (with the cameras and plugs) to the up or down, it changes the angle drastically.
The GPS is quite bad also.

Tilting does'nt affect the angle in my SGS...
Its possible that you're using it somewhere that is causing angle deviations. Like near metals, magnetic field etc
Gps is quite Good. It gets locked within 2-5 sec without any wifi/network assistance. Don't know why some people have issues with their GPS in SGS.. :-\

Is there another way to recalibrate, a hard way, maybe? Moving the phone in the eight pattern seems to calibrate, because it points to the magnetic north, but it's not steady, as I mentioned before.

Probably not. Until now, 5 different modems: JPA, JPE, JPX, JPY and JPG.
After some research, the only way to fix a faulty compass seems to put the south pole of a strong magnet in the north pole of the compass, then repeat vice-versa. I don't think I wanna do that. I hate to send my phones to be fixed, but I'm running out of options.
For some reason my compass seems to be poorly calibrated and when I use Google Maps the navigation works, but I sometime lose direction. In order to fix I need to rotate my phone in all different ways. But after a reboot the compass goes back to being off. Does anyone else have this issue? Is this a defect or software?
I found exactly the same issue yesterday trying to navigate around London. Google maps has been dodgy lately on my note 3, xperia z and my girlfriends HTC one s so I put it down to a bug, I might try another navigation app to see if it's the phone

Are you using a case? Particularly one with metal in it such as an s-view case. If so, you have to recalibrate the compass after every reboot.

this is not dependant on cases etc., same here as on note3, ... : with each reboot the calibration resets. maybe this is how samsung wants it to be!

Do you have same issue?
This has been an ongoing issue with Samsung Phones. This is my 3rd and and none of them have worked correctly in Maps, without navigating.
When you are just driving around (not navigating) you are using the compass....
When you are navigating, Maps is using the GPS and comparing your last point to your current point to determine your direction of travel. This causes navigating to work right and non-navigating to be wrong.
I have not found a consistent solution. Also on Google Skymap, with the AR type view, it is nearly useless for this same reason. It can't seem to sense your proper orientation due to the compass issue. (though I admit to not trying skymap on the Note 4)
Its not so much a bug, as it is Samsung and Google doing things differently.

So you have this issue with the Note 4 when using Google Maps while driving? Moving my note in all directions calibrated it but then reboot forgets.

I dont mess with the recalibration process. Its annoying and i hate it, but its not so bad that i recalibrate. I also dont reboot very often, but in the past, the recalibration doesnt stick for long even when not rebooting.
I love google maps for navigating, but it sucks for driving around. The biggest issue is that the screen turns off on its own when not navigating. Waze is great for driving around, it doesnt shut off the screen, and gives you all the traffic info you need. It also routes the voice through the phone regardless of if you are connected to the car by bluetooth. The biggest complaint with waze is that it isnt multi window compatible. On my rooted note 2 i used waze on the left of the screen for traffic issues, and maps on the right side of the screen for navigation.
I've been trying to calibrate my compass in Google maps but no matter how much I try, the accuracy is still "Low"
Anyone else having this issue?

Thanks for the video. I downloaded a compass app and it was not responding at all. I just rebooted my phone and it's working again. Very strange.
Mine too. I followed the tips in the video above but it's still not really working. Whenever I open google map the accuracy is high initially, but if I move the phone toward another direction the beam becomes wider and turns to low accuracy. No matter how many times I calibrate it's still like that unless I restart the phone. Weird. Not solved yet.
I have problems with Google maps it is inaccurate, it jumps to different streets, unknowing which direction I am heading. I tried to calibrate, I deleted cache, updated, the only solution I found to uninstall all updates and going with the stock apk.
