Recently I was getting a kinda weird effect. My compass now always directs to the bottom of the phone/screen, except when it is in open state. I think I have magnetized some parts somehow, and it is kinda disturbing when I want to use Layar or anything else what uses the built-in magnetometer.
Is there any way to fix this?
Theoretically putting the device into a simple depolarized magnetic field would solve the problem, but I don't know if it will damage the phone itself or not.

There are no magnetic components in the phone.
That means that it can't be magnetized.
I'm sorry to say that your magnetic field sensor itself is shot.
Note that putting the thing into a demagnetizer, if the sensor wasn't already dead, would DEFINITELY destroy it.
How do I demagnetize my cell phone screen
Actually phones have a magnet for the compass function and apps such as google maps to show which direction you are facing. Also, if you put your phone near magnets a lot it might magnetize metal parts in the phone messing up the compass. Demagnetized get your phone would demagnetize both the unintentional magnets and the magnetic compass. Please don't do that.

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.

compass
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.
I realized that the compass always hunts since I installed the steelie car mount; the metallic ring is actually attached on the UAG case and seems to stays very strongly magnetized since first install.
As soon as I remove the case the - mostly mapping - app I am using starts working fine.
Do you think the permanent magnet on the phone can cause issues, other than the compass loss? Do you know Google background services or other background apps even use that sensor?
Sent from a pizza..
I've only now discovered that the issues I've been having with certain apps are because the One has no magnetic compass sensor, only a digital compass. Is there any way to enhance the compass accuracy or otherwise calibrate it?
I ask, because when playing Ingress, my orientation is never even close to correct. I have to manually adjust the screen (while driving, ACK!??!) if I want to follow along with the route I'm driving, and of course the arrow is never pointed in the right direction which can make deploying resonators a little more confusing.
I'm also starting to get into geocaching, and without a working compass app, I have to carry another phone or an actual compass along with me. So spur of the moment geocaching can only happen if I happen to have one at the time.
And of course I'm sure everyone's heard about Sky Maps not working properly either, which is just a bummer.
Bumperoonie, Surely someone out there has similar problems or the knowledge to tackle this... anybody?
I am having a hardware issue with my phone. I was wondering if there might be a software work-around to it. The sensor that detects the removal of my s-pen fires off randomly. I've set all of the settings so nothing happens (no air command, no vibration or noise) when these misfires happen, but it still wakes up the phone randomly. The misfires do not happen when the pen is removed. I tried a new pen but that didn't help - so the issue is on the phone.
So, I was wondering if there is some software solution that will trick the phone into thinking that the pen is always out - basically disable the signal from the sensor. I opened the phone and I found the magnetic sensor that triggers this but I really don't want to remove or replace it. It would be hard if not impossible since it's right on the board. I know this is an odd problem and I've not seen any reports of anything similar, but I was hoping that there might be some ideas out there. Thanks for your help!
PS: My note 4 is rooted.

Flash cyanogen based roms like cm12.cm13.resurrection remix
This roms are stock android like nexus phones and actually spen dosent works except with 3rd party apps.the spen detects aircommand only with touchwiz roms. so you dont have to worry if the pen is in or out it wont detect.if Hope that helps

Thanks. I think I fixed it. I had replaced my screen some time ago. The adhesive had become undone and it was pulling away from the board. I opened it up and glued it down. Seems to have worked.
Hey all,
I moved recently and now rely a lot on google maps (and other location apps) to go to places.
Whine the location of the device fave been spot on, I have an issue with positioning and vector... What I mean is the device reports direction with a 90-degree error. If I am on the crosswalk facing one of its directions, the phone shows me that I'm perpendicular to the crosswalk and when I move up or down the crosswalk, it shows me moving sideways... not sure how to explain it better...
If I'm in a car and moving, the dot moves correctly on the map but I'm being shown as moving sideways on that map...
After doing a Google search on the issue, it seems that other people are also having this problem.
I've tried recalibrating, using the live view to calibrate (which works for a moment and then breaks again) Also tried clearing the cache of google maps, (but other GPS apps are also affected)...
Does anyone know how to deal with this problem?
Try turning off improved accuracy or vice versa...
Clear system cache.

All of this has been tried. even board replacements does not fix it...
it seems to be some kind of a software issue...
Screen rotation is set to manual or automatic? Try switching your settings.
Google Play System Update is up to date? Should at least be from 1st March 2022.
we have a crab in disguise among us... 'transformers~~ shell fish in deguise~~'
jokes aside, the GPS is known to be very unstable. I have the issue come and go... and from what I've heard it's due to signal disturbances.
You'll want to report the issue to Google if you are using Google Maps
Use common sense (or develop it) to navigate.
Constantly being led by a smartphone on the streets is a lousy and dangerous way to live.
Develop a mental picture with critical way points of where you are going and then concentrate on navigating the real world by memory. With practice it becomes 2nd nature.
If it's a complex navigation effort break it down into manageable blocks with start/end way points.
For the car a dedicated GPS is more practical and reliable, but you still need to use common sense for when it glitches... and it will.
GPS is just an aid to navigation... like a map.
Do you have a permanent magnet somewhere inside your phone case, or other source of magnetism that would confuse the on-board magnetic compass?

KingFatty came up with my initial thought. Might be some magnetic interference.
I do know the exact issue you are talking about though. I knew I was facing south (I have an actual compass) but my phone said I was facing east. But I solved it with a simple recalibration. I have to recalibrate at least weekly.
You say you have had board replacements to rule out a hardware issue but if it was a software issue then surely everyone would have it? I can confirm that right now, the orientation is correct on my phone. It could be a firmware issue for your specific device but this requires the manufacturer to fix it.
That leads me to think its some kind of outside interference like a magnet in a case.

Samsung's don't like magnets, truth
It may be the earth's magnetic field in your location. It isn't uniform.
It's actually began a cyclical pole shift which will take hundreds of year to complete. Magnetic anomalies with become more common as the reversal draws closer. I doubt the latter could be the cause but the former could.
I think magnets may indeed be the issue. My bag's phone pocket has a magnet on its latch so it might be the thing confusing the phone. The problem is that from more than 20 different phones I had over the years, the S21 Ultra is the first one to exhibit such side effects from magnets...
I use a car mount with wireless charger, and the mount itself creates a magnetic field that confuses the phone's compass so the phone re-calibrates the compass based on the navigation driving etc. When out of the charger, the phone is still interpreting the compass as though it's in the mount with the magnetic influence, so you just need to recalibrate the compass and it will fix the issue until next time it automatically recalibrates while under the influence of a magnetic field.
That's just how compasses work, they sense existing magnetic fields, and the closer a magnet is to the phone, the stronger the field. If only there was a way to tell the phone you are putting it next to a magnetic field so it knew not to recalibrate itself at that time.
