Compass,magnetometer doesn't work!

Hi all! I had my Nexus since New Year and I'm so pleased with it. The last 2 weeks have I just noticed that my compass doesn't work anymore. I have checked several calibration apps but nothing works(twisting it around it's axis etc) . I then tried "advanced tools" application. Here could I see that my phone got zero signals from the compass and the magnetometer! I have switched from stock to m5 just to see if it was software related but the problem is the same. It is like the sensors is out... So my question to you all: Is it any way (through root for example) that I can force reset the sensors or is maybe service next?

Did you flash any custom ROMs at any point?
I got a fresh Sprint Nexus. Compass worked fine. Flashed some custom ROMs, and compass didn't work with any of them. Next step recommended by CM9 folks is to revert to full stock to see if it works again to troubleshoot, but I won't have time for a while to do this.
As noted elsewhere in other posts, compass just doesn't work. It's not just N/S being reversed, it just goes haywire with any tilting, etc. Calibrating doesn't work from Compass or GPS Status.

That's the thing. I was on stock when I noticed the problem, that was why I switched to M5. But the compass is totally still for me. It doesn't move at all. It's totally non functional..

Try to calibrate the compass. I am on AOKP and compass is also not working proberly. After calibration it does. Here is how to do it (I'm not a native speaker, try to explain it):
Start an app which is activating and using the compass. Stand free and hold the Nexus parallel to the floor facing the screen to the ceiling. Draw an 8 several times with the phone keep this orientation. Then, hold the phone upright to the floor facing the screen to your face and draw an 8 serveral times, again.

Did exactly that with Compass app and GPS Status. Neither works.

Anyone have any progress with fixing this?

This is posted in the Sprint Nexus CM9 thread, might provide some information. Same compass problems happened with other CM9-based ROMs I've tried in the past.
I popped into the [CM9] IRC channel a little while ago and talked about how the compass was broken. It was suggested that I do a complete flash back to stock and report back. Trying to document as best as I can:
1. Complete flash back to stock under "[ACS] Return to stock" thread in this forum, used the first big link for FC12 Stock .tar (md5: 638d9b052b45396be345727ec0eedd64), which curiously is linked to "http://www.shabbypenguin.com/ACS/devices/Samsung/Sprint/GNexus/Stock/FC12/code_i9250xxsph-l700fd01.tar" and not *fd12.tar, like the mirror links to.
2. First reboot, downloaded Catch.com's Compass, compass works.
3. Baseband version lists as L700.05 V.FD01 / L700.FD02. I had previously flashed "toroplus_full_radios-FD02" a while ago.
4. Used Galaxy Nexus ToolKit v6.1, did option 7 for "all in one," though bootloader was already unlocked. Powered off, powered on, compass still works.
5. Copied over backed up zips, etc, flashed "toroplus_full_radios-FD02," rebooted. Compass still works. For kicks, updated to latest Google Maps, and Compass still works, GPS locks, location is correct. Baseband version lists L700.05 V.FD02 / L700.FD02.
6. Wiped system/cache/Dalvik & did factory reset. Flashed latest CM9 nightly (20120509-NIGHTLY-toroplus), GApps (20120429-signed), rebooted. AAAAND compass is broken again, as before.
Hope this gives you guys some information for a fix.

Icecoldsandwich 8.4 and 8.5

I've been using 8.4 since release as it is so far the only version that has allowed my GPS to work for more than 2 minutes. 8.3 and now 8.5 both get a lock in seconds but then loose lock and search until I turn GPS off and on again or restart the app using GPS. I have fastfix installed and working but only 8.4 will work. My question is can anyone tell me a radio that works with 8.5 and the soon to be released 8.6? I'm also getting the 1-2 second silence on 8.4 when a call connects so really would like to update ASAP.
Many thanks to anyone who can help out,
James

If your on at&t try the new radio that just came out (.11) I also tried radio (.19) which seemed pretty good to me. But radios are based on your region not on rom.

I'm over in the UK and on T-Mobile, I'm currently using 26.14.04.28_M Maybe just testing a few out is the way forward...
Thanks for your reply

Update:
Just installed 26.16.04.09 radio and reflashed 8.5, I get lock within 2 seconds and permanent loss (searching) after about 2 minutes. back to 8.4 I go...

I've now tried:
26.13.04.19_M
26.14.04.28_M
26.16.04.09
26.09.04.11_M2 (now current as signal + GPS seemed to be quicker and better than the other radios)
With all the above on 8.5 GPS would lock then slowly start drawing a larger and larger blue circle around my position in Google Navigation until searching appeared and stayed. It seems like the ROM is the issue to to me, some way it handle the data passed to it? In 8.4 the indication of lock (the circle with the dot in the center) appears to have lost the sat lock, but the software is able to continue giving a near perfect lock of it's global position. In 8.5 I notice the software gives up around the same time that the phone starts to indicate it has lost lock. Could that be the issue? 8.4 ignores the instruction that GPS is lost and 8.5 goes along with the data passed to it? Sounds odd but it seems that is what is going on...
Does anyone else get this? or do I just give up and get a new phone...

Volume wheel stops working

My volume wheel only works for the first 15 minutes or so then and then it stops working until I reboot the unit.
Any idea ? Software or hardware fix ?

A few have the same issues. Myself included. For me it was software related. Out of interest what navigation do you use.

I agree, since a software reboot fixes it I'm guessing it a software. Did you find a fix ?
I'm using Waze

Waze was my culprit. Try an alternative as an experiment.

Unfortunately, Waze is the reason why I bought the head unit. Although I'll try to see if that's the problem and if so ask Waze if they can fix it
Thanks

Some others have went back to an older version of Waze. The last one before the change in material design.
Some others with same problem have discounted Waze so it's a bit of a lottery.

Just noticed I have the same problem as well (volume knob stops working after a few minutes, reboot fixes it for a bit, repeat). I don't know when it started as I've always just used the steering wheel controls for volume.
Kicker is that I don't use Waze nor have it installed.
Using latest (Apr 23 2016 RK3066 800x400, latest JY MCU) Malaysk ROM, basic JY headunit.
@gk66 - since you last wrote your post, have you had the problem occur again despite using the older version of Waze?

I don't use an older version. Ditched Waze completely. Use Google maps. Problem hasn't resurfaced yet.

Ah, I should learn to read. Thanks for the info though!

I haven't done extensive testing but Waze seems to be the culprit in my case too.
Muting waze also works. I've set it to "alert only" and it's much better but still stops from time to time.
When Waze talks it lower or mute media volume, my guess is that Waze does it wrong or uses an old API, I've had problem even on my phone where media volume would stay low or stop altogether.
I'll make a bug report and hopefully they can fix it

Thanks for that. Glad you've found the culprit.

Waze is not the only cause, also this happens with pc radio with the latest malaysk firmware for rk3188

Nobody said it was the only culprit. Why not start a thread to identify all the culprits

I'm having the same issue. Radio works fine until I launch waze, within ten minutes the knobs don't work anymore.
Since everybody is having sporadic issues, I'm actually testing out if the audio mixing you can set in Settings->GPS has anything to do with it. I always had it set to mixing, and I now put it to switch. Tomorrow I'll know more after a round trip to work.

No waze here, yet I have the same issue. Happens out of the blue, even when just running the original radio apk and no navigation at all. The SWC keeps working. Functionality returns after a reboot or a jump to the hardware settings. As the SWC always functions I don't mind TOO much but it a bit sloppy.

Tried changing the GPS settings today. Whatever I did, nothing helped, not even putting a random app that doesn't produce sound as my navigation app.
Which MCU do you all have? Mine is JY/Joyous...

Waze is not the culprit, it just happens more often when using it. Bluetooth calls (interrupting your current audio) often break it. Other apps switching audio break it too.
It is most likely some bug in the firmware related to switching the audio input.
There is no solution found yet.

KLD2, RK3188 SD. Came with KLD2 v2.77 firmware, now running v2.81. Both have the issue. I haven't tried flashing older firmware

I tried using tomtom as my main GPS application, same issue, so it's definitely not Waze specific. Friday I'll drive without using any GPS app and see if it still fails.
Next time as soon as I notice it failed, I'll check system log for any errors or exceptions, perhaps something stands out.
I do know that the turning of the knobs is logged in the log even after they failed and don't change volume. One of the xposed modules that shows the buttons pressed and such does not recognize turning of the knobs after they have failed...

Hmmm. The system log still gets the volume knobs turning but not the app? That could mean the firmware is ok and the bug is somewhere in the Android audio?

Yeah that's why I started playing around the GPS settings...
Any idea which app/service is responsible for handling the volume knobs?

Fulmics ROM 6.1 Bluetooth issue

Hi,
I have installed Fulmics ROM 6.1 and I have issues on bluetooth (i remember that i had already this issue in stock rom 6.0):
when connected to radio car or BT headset or Heart Rate Wristband , the BT turns off randomly on phone and i have to turn it on again on phone...
The frequency of this issue is random: sometimes it doesn't turn off, sometimes after 5 min, 15 min, or more.
i have tried to reflash modem 21c and 21a, same issue...
If somebody have an idea...
Thanks (sorry for my english...)
LG G3 D855

Did you delete the system before flashing rom in twrp

I'm also having a problem with bluetooth on the 6.0 rom. And this is a feature that I always use to listen to music so I really would like to find a solution.

PX5 freeze

Hi,
I have a PX5 RK3368 car radio with MCU MCTE_HLA_V2.80b_2 (recently updated from MCTD_HLA_V2.47_1). When I use the pre-installed app for Bluetooth A2DP (bluetooth music), after a while the radio freezes completely, continuing to play music, but no longer responding to touch commands (the screen is completely freezed, even the information it shows). I have to reboot the radio to use it. I've noticed that sometimes it happens with Chrome, too. Is there a solution to the problem?
Thanks

I have the same problem on my xtrons 10.1 using the play store or Google chrome seems to cause this for me. My MCU is GS version 3.40. I get random black screen boot up errors as well.

@bamaredwingsfan try to change the ROM to one custom (like Hal9k's one). This seems to have solved the issue

That's what I'm about to try later today. What specific brand radio do you have? Also when you installed the update did you do it from recovery, or just load up the update zip and plug in to the radio and do it that way
