Compass consistently off - G2 Q&A, Help & Troubleshooting

I've got a stock, rooted D801 running 4.4.2 and I've been having problems with my phone's compass. The problem is that even after calibrating, the compass is always off by about 15°. This is the second G2 I've had with the problem, and with the first phone, I fixed it by deleting the akmd_set.txt file in /data/misc. However with this phone, I can't find the file anywhere. Does anyone know the name and location of the compass calibration files?

Compass requires constant calibration?

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?

Google Now working intermittently

Is Google Now only working intermittently for anyone else? Lately, as in the past week-week and a half, Google Now seems to only work sometimes. Ive been having to constantly open, refresh Google Now and even that doesnt work a lot of times. Is this happening to anyone else? Is there a fix? Is it a server issue?

Did this issue get resolved for you? I have found the problem and I temporary fix.
The issue is related to the new Google play services 3.2..they changed location to use wifi as Android 4.3 has it on at all times.. This is to save power from using GpS.. Anyway if your not running 4.3 and have wifi on all the time your location based cards will not work...
The solution, downgrade to Google play services 3.1 Everything works great on 3.1..

[BUG] Compass not aligning properly [VIDEO ADDED]

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.

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.

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.

Auto Rotation Issue

my auto rotation doesnt seem to be working. it just stop working and sometimes comes back if i reboot and sometimes doesnt. i first experienced it on a touchwiz rom, so i decided to flash an aosp rom and still the issue persists. i also tried some solutions i found after searching but none worked either.one thing i do knw is i dropped my phone a few days ago. could it be possible that the drop damaged the sensors that control phone orientation? any one have any suggestions on how to fix it?

compass wont work with any ROM

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.
