Hi, I have a problem with the compass on my UMI zero. When I use google maps or any compass app the direction pointed by the arrow is always the same whatever direction i rotate my smartphone at. Only sometimes it points in the right direction but slowly rotating to the same wrong one. What's going on? I tried to install different ROM but the problem was never solved, and at the beginning it was working, i cannot say flawlessly but at least acceptably.
Compass problem
i was facing the same issues as you are with UMI Zero's compass especially on its stock firmware (update 3.10), but i went ahead and got the rom from this thread
http://forum.xda-developers.com/and...-miumizero-miuiv6-umi-zero-t3050090?nocache=1
and installed the firmware available on it.
i also made sure that all GPS settings were on before using the compass because without it (try using it with the data on for the first few trys), it kept telling me to wave the phone in the shape of an 8 to recalibrate it. it works now much better than before but it is still not completely accurate. i think the problem is within the hardware rather than the software.

I just fixed the magnetometer on my Vibrant, using advice found on another site. It took me a long time to find it, so I thought I should post it here to help other Vibrant users find it more easily. There is similar advice in forums for other Galaxy S variants, but nothing here.
About a week ago, I noticed that my phone was no longer sensing its position. The screen would not rotate, and the compass was not working. I ran the sensor test using the *#0*# code, and both the accelerometer and magnetic sensor were stuck on one reading regardless of phone position. Rebooting had no effect.
I found the following procedure on a different site. I would post the link to give proper credit, but I don't have sufficient forum privileges because this is my first post. It was on the dp.nonoo.hu blog.
Your Samsung Galaxy S phone’s compass is not working? Auto rotation is faulty? Check your hardware by dialing *#0*# – this is a factory test app for the phone.
If the compass is broken there too, here’s how you can fix it: delete /data/system/ms3c_yamaha.cfg, and if there’s a backup file, delete it too, then reboot.
If it won’t help, make sure the files are deleted and then run /system/bin/sensorcalibutil_yamaha from a root shell, follow the instructions and then reboot your phone.
I deleted the file using RootExplorer and rebooted. The accelerometer and magnetic sensor were working perfectly.
Lol I fixed mine by simply flipping the phone a few times. Basically I first downloaded and installed the compass app from the market. Then in the app, I calibrate it normally (wave in a figure 8 pattern) a few times. It will still be pointing incorrectly so next all I do it flip the phone on it's vertical axis a few times then repeat with the horizontal axis. Then it will be correct. This always works for my phone, I do it every time after a factory reset since it uncalibrates the magnetometer every time. I've never had problems with the accelerometer though, only the magnetometer. It would always be out of whack no matter what until I figured out what to do.
Cheers Blue,
This fixed it for me.
I cannot find neither the .cfg fila and or the configuration app.

These files do not exist in ICS AOKP on my Vibrant and my magnetometer still points in the wrong direction lol.
Trying everything I can find on the Internet.
Edit: Removing the battery does not work even after 15 minutes. However, flipping the phone end over end worked immediately. Seems strange that this is not mentioned by any of the Compass apps yet they tell you to draw figure 8's in the air which does nothing on my Vibrant. lol
Thanks to the individual who shared that tip.
same here, a few vertical and horizontal flips did the trick for me. (on ics passion)
Didn't find the "/data/system/ms3c_yamaha.cfg" on my GalaxyS running Slim ICS 3.2. Seems like ICS doesn't have this file. And some vertical/horizontal flips almost did the trick. Now the compass is moving, before it wasn't moving at all. It not showing very good direction like it used to when I first purchased the device almost 15 months ago.
And one more question, does anyone know, what is the testing code for ICS? Because *#0*# isn't working on ICS. I used this code while on gingerbread and it worked before. I thought this code is universal, but now it seems like, its not.

1. Doest it still work when the phone is:
- touched with a little magnet like in a standard vertical flip-case (with little magnet) or
- travelling by car/bus/train or
- plugged in headphones
In the one I had (I don't have it any more) while plugging in headphones, or travelling by car/bus/train, or putting it in an flip-case with a little magnet the arrow In Google Maps pointing the direction which a device is currently facing simply freezes. Compass app also freezes at the same time. The app called Android Sensor Box in the scale for magnetometer reaches its maximum level. While moving the little magnet, from mentioned before filp-case, around a phone the arrow travels with it. Move it away and it freezes. It simply won't move. While sticking S4 to the metal part of laptop table the arrow immediately points opposite direction. Only making 8s in the air helps but only for a bit. Neither S3 9305 nor S5 have this problem. Even when stuck with a magnet their arrows in GM works just fine.
2. Does deleting the file fixes the GM's arrow issue also?

**** this worked
This is a known issue on Gingerbread and there are literally thousands of messages all over the web (Google: Gingerbread Compass) but I thought it was fixed in Honeycomb.
I downloaded 3 different "basic" compass apps to test with and they all have the same problem. Most of the time the compass points SOUTH or SW or SSW and not north. Other times it just randomly points where it wants or when you rotate the tab the north arrow just rotates with it rather than locking in on NORTH. Sometimes it just keeps shifting 10-15 degrees back and forth when the TAB is sitting still on a wood table.
I use an app that requires the compass (Dishpointer Pro) and needless to say it's totally useless. I have tried the "figure 8 calibration" and it doesn't help.
Note that the compass is not the same as the GPS. My GPS works fine.
I have the same problem on my Samsung Infuse when I load Gingerbread but on Froyo it's fine.
I've tried a couple different ROMS on the TAB with the same problem. Funny thing is, I don't think I tried it on the stock ROM.

I'll check it for ya bro. I've never actually tried to use a compass app yet
I have gingerbread and the compass on my phone, both phone and tab compass appear to be working.
I didn't use Compass app but on GMap, the arrow points to the correct direction for me when I'm stationary (so it is not caculated via GPS). On my phone, it never works reliably.

Do you have your tablet in a case that contains magnets? If so, those magnets may interfere with the compass.

If your GPS is enabled in the hardware settings as soon as you load maps the GPS is functioning. I have no problem using any program that supports & uses GPS only compass. You can tell if the GPS is on by the little circle that looks like a "sun or a compass" when you run maps or nav. If it is showing it's using GPS.
My arrow in maps follows me perfectly. Just can't get any compass program to work including Dishpointer Pro which is what I always need to use.
Same as me only google map work.
Anyone else notice this about the compass? If I open a compass app (tried many) the compass is either erratic or stuck, but if I calibrate it with GPS Status app, it is fine until next use. I am stock rom and rooted.
Just a weird annoying issue.
I don't remember having this issue on other phones.

There is already a thread about this in the General section.
OK, i see it now - but it is a month old, and it really doesn't answer my question. And since this is the Q&A, help/troubleshooting area - it seems an appropriate place to ask.
I still have to calibrate my compass every time i use it. Does anyone else have this issue?
Anyone else who has an N900W8 have weird compass issues? It sometimes doesn't rotate or does not align properly.
Strange issue on my Note 2's compass too, sometimes does not calibrate properly, AND is running 4.3 but on AOSP. Is there a build problem/Samsung problem? Or is it hardware and I have to get it changed?
VIDEO: http://youtu.be/T1U5qlPABRo
Nope, after a day of usage, it just locks into a position when I rotate my phone on a horizontal plane. If i tilt my phone left right forward and backwards the compass moves.
To calibrate it, I have to shake my device hard and spin it like I am opening a door knob many times. Then the compass will work perfectly.
Anyone have this issue? N900W8. Is this normal to calibrate a device? Is this a recurrent issue amongst users?
No one has this problem? Will I have to take it back for a replacement? It still works, after a rigorous shake, but is this calibration abnormal or not? Will there be a possibility that a software update could fix this?
I have kinda a similar problem, in maps if I'm using navigation the arrow doesn't align correctly to the direction I'm going, not much of a problem.don't know if it's related to the GPS or the compass in my case

Can I safe to say that there is an existing Compass Bug in the software and not have to replace it? I will be uploading a video soon.

Hello,
I have had the same problem. The solution is so simple:
1- dial *#0*#
2- choose sensor
3- here you will find that the status of your magnetic sensor is: "need to calibrate". So you wave your note 3 in 8 patterns for one or two times
4- and here we go, the sensor status now is calibrated and your problem is solved
P.S.: if you have a problem with *#0*# you can use any compass application or google maps, and then you continue with 3 and 4.
Hope that it helps you
Hi Kaderoid,
That's not really a calibration method, but thanks for your help. My device just spins and spins and spins no matter how I much I try to calibrate it. The only way I can fix it is by rebooting.
That's the difference, and plus magnetic interference happens too often it seems like it's a hardware issue.
Sent from my fingers to your face using my Samsung Galaxy Note 3!
So, do we have a solution or a fix to this issue? My Note 3 has the same issue.
I had the same problems, display didn't rotate, after a couple of days it seems fixed, but now doesn't rotate again.
I'm Italian, I'm hope that the English is enough good
Hello,
I had some issues with my Compass. When using GMaps it was not pointing in the right direction. I changed my device and the new device has the same issue unless I calibrate it. Once calibrated it works perfectly. I guess your device is having a hardware issue. Get a replacement.
I have the same issue on 2 Notes 3. I also had it on 2 of my previous HTCs. I think it happened after GMap update a few months back.

when you enter *#0*# and compass arrow is red just do some spins with phone. It turns green and compass works proper
This is calibration method
I did this, and my whole screen went green for a bit and the phone vibrated, the compass however has a blue line with 3 under it.

If it went green your phone's proximity sensor was triggered either by an object close to the top of your phone.
3 means it is calibrated at sensor level 3
I have a similar issue. If I restart my phone I have to recalibrate the compass. Once calibrated it works fine though.

I have the exact same issue. Sometimes I will calibrate it and it will fix it. If the phone has to reboot it will not work again.
Using GPS Status & Toolbox, the compass was "locked" in the wrong direction.
So I rotated around and as soon as North indicator was actually pointing North, it seemed to lock-on and was working fine (without performing a calibration).
Weird and I hope it gets fixed in the next update.
Hi,
I have been using P9 lite (model L31) for the past few months and found that the compass has some issues. Even if I calibrate the compass using figure 8, it does not stick to one point. For example, if I use google maps walking navigation, the map keeps on rotating so much that its hard to find the actual direction. Though the same does not happen in car navigation mode.
I have experienced the same thing in other apps as well. The compass does not stick to one position and it keeps on rotating.
Does anyone experienced this issue?

Even granting location access to the default compass app of the phone does not help. Does anyone has any clue why is it behaving like this?
Same problem on a L21.
Compass used to work fine, but since a few weeks ago it does not point to magnetic N... not even to a point with a certain deviation (if I rotate the phone, the "north" also rotates with it).
My good old N8-00 compass still works fine...
After A LOT of 8 shaped calibrations (with and without GPS enabled), the compass seems to work again...
