[Q] Is the compass a failure in the Note 2? - T-Mobile Samsung Galaxy Note II

I've had my Note2 for a little over a week now, and think it's a pretty cool device. Today I saw something about the ISS and realized I hadn't loaded Google Sky yet, but then I realized I hadn't tried my compass yet. I downloaded an app and found the compass useless. I then tried GPS Test and get the same results. Then I found this thread in GT-N7100 section which describes a neat test mode (dial *#0*#) and in that mode when I test the compass it does the same thing; it jitters wildly, and tilting the phone side to side sends it spinning. I dont know if this is a dealbreaker yet but this is not a good failure to find when Im right at my 2 week return window.

after read your post, i did retest ( I did test before ) using Compass & Gps test app . With Compass app its pin point exactly where im at , Gps test app i got 23 sat in view and 19 in use.Hope its help

I just tested my note 2 with street view, and I also found the compass does jitter a little bit, not too much. But enough to effect the experience of the street view.
In general, the compass does find its north, and the correctly location of where I am. And all my map functions do work fine.

I'm having the same trouble with my SPH-L900 sprint. See YouTube video. It twitches while standing still but while driving around it goes nuts.

[Q] GPS wandering, any one found a software fix?

I've read just about every post in this forum that even mentions GPS trying to find a solution, but no luck, so I'm asking outright in case I missed something or someone has the answer and hasn't contributed it yet.
My One X has horrible GPS.
I'm not talking about how long it takes to find satellites, it does that quickly enough. What I'm talking about is using an app like My Tracks, Endomondo, Run Keeper, etc to record a track. If I sit the phone perfectly still and let one run, the position and track wander all over the map like a drunken sailor looking for a good time. If I actually move in a straight line, the position shows me blocks away from where I really am. If I try to use a navigation app, the directions are meaningless because the phone thinks I'm as much as 1/2 mile away from my actual position. (I should post a video of that, it's hilarious how bad the directions are.)
Please don't respond if the only problem you've had with GPS is that it took too long to find satellites and downloading someone's aGPS fix app or tweak solved your problem. I've tried all that, multiple times.
I suspect it's just bad hardware, maybe bad antenna connection or something similar, and I'm going to need to replace the phone, but before i go through the hassle of trying to get HTC to replace this dev unlocked phone, I want to make sure there's not a software fix possible. I'm past Expansys' 14 day return window, so HTC is my only option, or possibly my American Express warranty service.
Any thoughts?
The pic is a screen capture of the phone sitting in my parked car in an uncovered parking lot for about 10 minutes. Note how much it wanders around.
Well, no replies, so I guess that means a big NO to any one actually finding a software fix to this particular problem.
For what it's worth, I installed CM9 in the phone and the GPS is still unable to hold an accurate location, so I'm sure it's a hardware issue at this point.
That's a real pisser, since they told me the turn around time on fixing my phone will be 3-4 weeks at the HTC Warranty Repair center in Houston, TX.

I hate to say it, but it must be your unit.
I use GPS navigation very frequently (SoCal, USA) - and coming from a flawless GPS on SGSII, I have to say that HOX GPS is even better. It's more precise - it can even correctly show which side of the road I'm on. Also, driving past intersections is spot-on, which shows how on-the-spot it is.
Did you install any cases, or keep it somewhere where antenna signal may get blocked?

I didn't want to believe it, but I concur it's got to be a hardware issue. No case in it, nothing blocking the antenna. I have same issues even laying it on a patio table out in the open.
I'm also in SoCal...San Fernando valley and the west side of Los Angeles. The one time I tried to use the GPS for navigation it was like getting affections from the three stooges.

Mine does exactly the same. Calibrating the compass an turning wifi off while using gps solves it for me. Gsp is spot on whe wifi turned off... turn it on while navigating and it wonders off road....
I had the same problem, I downloaded GPS Test Plus from the Market, went into settings, selected Clear AGPS and then selected Update AGPS - seems to have been tons better since I did that.
Found this via an Internet search so Kudos to those who discovered it although I apologise I can't remember where I found it!

Yop this I remember even from the iPhone. Accuracy +50m when Wifi or Mobile network assisting with the position. Without max 5 . and not much wandering
Just turn it off in the location. As the breugiek above me suggested.
Thanks for the responses.
As stated in the original post, this is not an aGPS issue. I've tried many aGPS type fixes..Faster fix app, crypted fix and a few others.
I didn't mention it, but I've already tried turning of wifi; it makes no difference.
I suspect bad hardware, specifically something wrong with the antenna.
Annoys me no end to be HOX-less for a month. I've only owned the damn thing for 4 weeks.

Mine is the same but only when I stop the car at lights etc. Sat nav shows me going rallying across field and drowning in the sea when near the coast, sorts itself out when on the move again tho.

GPS now working fairly well on this phone. It's not perfect, and requires WiFi off, but other than some initial wandering at startup I'm getting accurate tracks on it.
The fix was to install ARHD 7.0. No idea what changed from earlier versions but it works well enough to put up with until I can get a shorter repair time quote from the warranty center.

[Q] Compass off by 90 degrees

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.

Here's a *possible* solution to bad compass...

If your Nitro is like mine, then its' compass couldn't find North to save its' life. Or worse yet it might be in the vicinity, but is very sporadic...Makes it just about impossible to use apps like Google Star Maps or get a proper bearing on direction in Nav when you're at a stop.
If you're also like me, you've tried doing the compass calibrations with the whacky waving your phone in a figure 8 to calibrate. But this hasn't fixed my issue.
But then I tried the rotate-all-axis calibration method and now my compass is much better! Here's what to try:
1. Install GPS Status from the Play Store:
https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2
2. Open the app, then bring up the Menu and choose: Tools > Compass calibration
3. Rotate the phone along the 3 axises a couple of times, like in this video:
http://www.youtube.com/watch?v=oNJJPeoG8lQ
4. Press okay and your compass *should* be better
NOTE: I just noticed that when I went to test on another phone to compare (I also have a Nexus One), that my Nitro went out-of-whack again and only after a short while from previous calibration! Another calibration and it's working again, but that sucks that it lost its' bearings so quickly like that.
Give it a try and good luck!
Didn't really work for me. I really think this is a hardware issue. Do you think we should demand some kind of rebate for this or something? I know (its somewhere on the threads) that LG officially acknowledged the problem and have yet to come out for a fix. They are knowingly selling a defected phone.
anybody test the phone with any of the new official software?
After calibration compass works correctly.

For how long? Work after a reboot?
After flashing a new ROM?
Yes, it works after reboot. But calibration will be lost after flashing new ROM. I dont know where its data is stored.

still sucks. all jumpy and not accurate.
I calibrated mine acouple of times yesterday. The compass worked, but it was very sluggish or spun too fast, and unless I put it on a table, wouldn't stop spinning.
I tried today, and it worked but was very slow to catch up to my movements.
Tried some sky map apps, and it just sucks. Same with the augmented reality apps.
wish there was a fix - or we at least new the problem.
thinking I may go back to stock and send it in to telus and see if there is a fix. Anybody have a working compass after a hardware swap? or repair?
The calibration did fix (even after reboot) the compass but I've noticed it takes sometime to settle after starting an application that use the compass.
At first it looks like the infernal spinning madness is about to start over again but after a few spins it stops at the correct position and stay there.
Weird...

Magnetic Sensor (Compass) is erratic

I think my Magnetic Sensor is off. Try downloading a program called "Marine Compass" onto your Note 2. On my device, it doesn't stay on one heading. It bounces back and forth by 1 unit. I installed the same program on my SGSIII. On the SGSIII it is stable.
I entered the debug/test mode on both the Note 2 and the SGSIII. I ran the sensor test on both units. The Note 2 seems to be more sensitive than the other. Whats also weird is the "Lux" meter. It's in the hundreds on the SGSIII, while it's barely 10 on the Note 2.
Anyone else notice this on their Note 2 unit?

I too have the note II and GSIII, and the compass is jumpy on the note II while on the GSIII it's stable.
yep, posted this in Q&A, compass is useless.
odd, my compass seems to be fine. doesn't the gps nav need compass to work correctly? i use gps all the time and it's a real blessing lol

when in motion the gps device does not use compass to tell the direction of travel. if the device is accurate then the direction or motion will be very accurate as well as the speed.
when motionless the gps device cannot tell what direction the device is facing and so some gps devices will use a compass sensor for this purpose.
that being said - I too have both SGS iii and the Note ii and noticed the same thing - that the Note ii north pointing needle is jumpy and it is not accurate.
there is a low wall in my back yard that is aligned almost exactly north south and using the Google sky map with SGS III the north star is perfectly aligned with the Google sky map. With the Note II, the north star and sky map not so much.
A picture worth thousand words:

Actually GS3 has the same issue, but it's not as bad though. And in my test's it would be little erratic only every other time, on N2 it's constant.
My compass is twitchy as well. Phone was built last month.
Hastily spouted for your befuddlement
I noticed this when I open up google maps and I'm not moving, the arrow for me is always pointing about 30-45 degrees off

really?
I doubt that google maps uses the compass to tell direction while you are standing still. On my devices the arrow point is completely off whilst the device is at rest.
As I pointed out in post #5, a gps receiver cannot tell direction whilst it is not in motion and the fact that the direction while the device is not moving is inaccurate indicates that google maps does not use the compass, at all, to tell direction.
I hate how useless the compass is. I haven't tried any of the satellite or skymap apps, but ingress jumps around erratically. A friend with an AT&T phone has the same issue. Really sucks that such a great phone has such a glaring failure.
At least it's not like LG Nitro HD:
http://youtu.be/xxxS_HZsRLU
So it's not that bad
Hmmm (if you freeze stuff with TiB, make sure lcdtest is not frozen), open phone and dial:
*#0*#
It should show bunch of different buttons, go to sensor, and start rotating phone in x, y and z axis until circle on the bottom start showing 3 with blue line (it was 0 with red line first time I entered there).
After that it seems compass become much more stable and accurate, at least for a while.
my compass is off by about 15degrees. this is my third note2. my first two were exchanged because the roll axis was off by about 6degrees, making racing games really annoying.
I have another 2 days in my 30 day return window. I think I'm going to exchange again.

I had the same problem for weeks.
I think I've finally found a fix for this. You have to be rooted.
1. Go to /data/misc/akmd_set.txt
2. Change permissions to -rw-rw-rw (or chmod 666)
Apparently the compass saves calibration values here. Because "system" doesn't have write access, every time you calibrate, it wont get saved.
Giving these permissions allows the compass to calibrate properly.
Results so far:
1. Compass finally works perfectly after calibrating.
2. Effects stay after a reboot.
(please hit thanks if this helped you!)

I don't know how to thank you enough for this, and it's working even on a note 3 I thought it had a faulty magnetic sensor. Did what you suggested and now it really is stable and accurate. :good::good::good:

Slow/unreliable gps lock and wonky compass

Anyone else have issues getting gps lock? It will take me several minutes with a clear view of the sky sometimes. If I'm sitting in the back seat of a car I often have to press my phone right up to the window to get a good enough view of the sky and it will lose lock if I take it away from the window.
Also, the compass is all over the place and makes things like gaps walking directions almost useless.

Are youon kitkat? If so, Pls check the 4.4.2 update thread in the general forum where we have a new stock image with fixed gps and battery. See if it applies to your case.
I've noticed the wonky compass. It will vary wildly without any rotation of the phone and, in one orienration, will flip back and forth by 180 degrees very quickly. Thought about warrantying the device, but everything else (including GPS) is solid.
I'm on 4.3.

I have to calibrate the compass occasionally but it works fine for me. GPS normally licks in 10secs or so, but I keep GPS on all the time. It only uses power when you are using an app that uses it.

ive had a compass gps issue for a good while. thought it was the rom, then thought it could have been the case....but im thinking its just happening because i get same performance from jedi's 4.4 release....so not sure what the deal is but same issues....they gave me a gps fix that tends to kinda work.....but its not tracking fluidly and the compass just isnt staying calibrated for very long...its always looking in a different direction.....
Download and install topNTP from the play store give it root access click install at the bottom select create files and reboot.
I use this app after every rom I flash and it gives me a gps lock in literally a couple of seconds even indoors.

My Note 3 doesn't lock on to GPS inside my house at all. Outside, it seems okay, most of the time.
My old HTC Dinc2 locks on without any trouble, inside or out. Not sure if I should do an exchange, since everything else works just fine.
