Just a simple question, does the compass work?
I'm running psx and noticed the compass didn't work in maps. So i downloaded a compass app and that didn't work either and reports a magnetic sensor error.
It does. Yours appears to be a defective unit.
Thanks for checking.
Yes it looks like it's faulty.
Just an update, it was my magnetic case stopping it from working.

I've noticed on my new S3 that the compass is sometimes off by 90 degrees. Then, if I close the map app and open it later, the compass is accurate.
This this a known issue?
Thanks!
Not sure about this issue but I know there is a way to calibrate the phone somewhere in the settings. Not sure if it will help or is even related but might as well give it a try.

I didn't find a compass calibration, although I recall seeing a gyroscope calibration setting hidden somewhere (I'll have to find it again). Would that help at all?
I tried a compass calibration using the GPS Status app, but it didn't seem to help. It's strange. Tried it again on my way into work and it got some of the directions right, but wrong on others. It also seems to improve over time. I almost wondered if it didn't have a magnetic compass and was just using gps signals to guess at your direction. As far as I can tell, there is a real compass in there, although I suppose I can't be sure Samsung is actually using it.
Same problem here...
I'm having the same problem here on all my devices, so i'm thinking it is more likely a bug in android than a hardware issue.
Calibrating the compass with GPS Status (on the play store, can*t post a link yet) helps but never for long... quit google maps or navigation, and on next use I have to calibrate again.
I just verified this one someone else's S5, same there.
Another interesting detail:
I used to have the same issue on my Samsung S3, but with CM on it all is well now... so it really seems to be a software thing.

interesting: there's a two year old bug entry about this on google: https://code.google.com/p/android/issues/detail?id=37771
...it has been closed as "obsolete".
nice going there.
I have recently got my phone back from repair and I have done some tests on it. It seems the magnetic sensor isn't working, most compasses don't work and ones that do are way off and seem to be using the gyro not the magnetic sensor. Hardware test apps report the sensor as there but no readings. Also the pedometer does seem to work either in the fitbit app as it does not register any steps.
I have used the Sensor List app from the store and these seem to be the only 2 not working. Is this just me or does anybody else have this problem?

just you mate all mine working fine
What did you use to determine they are working? I have used the native hardware test using the code *#*#3424#*#* and it seems to fail there too. Apparantly the hall sensor test which is the magnetic sensor is supposed to show the clock when a magnet is put near a blue square on the screen. On mine it doesn't, but instead it turns the screen off and I can hear a click . However the magnet is fairly powerful so it maybe affecting something else. There doesn't seem to be a pedometer test and all the other tests seem fine.
Thanks
Using Google Maps, Here and other gps app I noticed that the compass provides wrong information and must be recalibrated every time.
I tried calibrating the compass using several described methods and compass programs but without luck. I get tactile feedback of good calibration, but when I start the app it notes that it senses an abnormal magnetic field and needs calibration.
Does anyone else have this problem or I have to make me replace the device?

Okay, I replaced the device and now the compass works.
hi there, i have this problem waht i have to do ?
:crying:

CM13: My compass is about 20-deg off from both a physical magnetic compass and my wife's iphone compass. I've tried recalibrating using the app, GPSstatus.
I know on my past OPO, I had to edit /system/etc/sensor_def_qcomdev.conf, and delete /data/misc/sensors/sns.reg to fix the same problem. But that does not seem to work with this OP3.
Has anyone else found their compass off like this? Does anyone have a fix?
So, I recently installed Lineage OS on my n7 and noticed auto rotate wasn't working. Then flashed it back to stock thinking the lineage rom was bugged, still no auto rotate, it used to work last time I used the tablet around 3-4 months ago, so im wondering did the gyroscope get fried or something?
Anyway which board contains the gyroscope, the motherboard or daughterboard, anyone know? Recently replaced the daughterboard so im thinking that may control the gyroscope? I want to replace whichever board contains the gyroscope as it doesn't even show it moving in check my android app, don't really want to waste money on the wrong board if possible, so if anyone knows for certain it'd be a huge help!

The gyro is on the daughterboard but it never fails. Connection of the wide silver cable between the boards is the problem - see my earlier post https://forum.xda-developers.com/showpost.php?p=66952073&postcount=3

But then wouldn't the gyroscope show as moving in apps that can test it? It shows up as stuck, and on the twitch app it acts as if i am shaking the tablet cause it just keeps going from dark mode to light mode because twitch app has a feature that allows you to shake to enable dark mode/light mode.
Anyway I have tried re-seating the ribbon cable about 20 times now and still nothing shows up on gyroscope, even tried 2 different cables

The gyro and compass sensors share the same I2C data line connecting the two N7 PCBs. Please check with a sensor test app if the compass works - if yes, then the gyro has failed indeed.
Some apps will show you the sensors names - N7 has:
gyro Invensense MPU-6500
compass AKM AK8963
:good:

Hmm, the compass seems frozen as well I don't understand though the ribbon cable seems to be fine no matter how many times I disconnect / reconnect it nothing seems to change... Very odd
I have same issue, I use rotate app to manually rotate and also automatically rotate some apps. Eg auto rotate YouTube and media player to landscape.

With the silver ribbon cable connected at one end try and get it tightly moulded around the battery hold it there and connect the other end. I found this out recently after a battery swap it helps to push the connecters in a bit more those few microns matter. I was having screen rotation problems after a recent battery swap after doing this everything's perfect again.
