[Q] Compass calibration - frequency and using a certain app? - Epic 4G General

I had a question regarding calibrating the compass. I've read the threads and seen the video about the compass calibration, but I did have 2 questions that I haven't been able to find the answer to yet:
1) How often does the compass need to be recalibrated? Is there anything that affects it - meaning, any actions or anything that may require the compass to be recalibrated more or less frequently?
2) GPS Status has a Compass Calibration option, and I've seen similar options in other apps. Do these options do anything like put the phone in a recalibrating-the-compass mode? Or can the compass calibration be done at any time? Does the screen need to be on? Does the phone even need to be on (don't know why I'd calibrate then - just curious since I don't understand what the calibration does)?

Does anyone know?

You would probably get a fast response if you posted your question in the correct section (Q & A) thank you will in general, jus sayin.

Personally I recalibrate (via the figure 8 method) any time I notice the compass is off. I leave my screen on (usually in Maps) and wave the phone around and it gets pretty accurate after recalibrating.

Pretty much anytime you haven't used the compass for a while, you will need to recalibrate. I use a combination of holding the phone straight out and waving it vertically (referenced to the ground) in a figure 8, then just holding it arm straight out and turn my body 360 degrees so that the phone has gone thru all the points of the compass.
Note, this is not the same thing as fixing the upside down calibration which only needs to be done once.

Oops, sorry about that...I should have posted there, but I can't move the thread now

When using Google maps, I have to "figure 8" my phone 90% of the time. Sometimes to get it to point the right direction or to just get the "pointer" to unfreeze.

[Q] Does the compass work...?

I've yet to find a Compass app that works on my Omnia7. I don't know if it's the lack of a GPS signal (been trying it indoors) - my old Hero used to work fine with no GPS signal as does my Wife's iPhone.
Has anyone else found a Compass app that works on the Omnia7 without GPS signal? I'm wondering whether my phone is faulty or whether the phone just doesn't have the hardware to get a Compass reading without GPS.
Isn't there a diagnosis code to test this?
Ya, pretty much.
One in the test menu, Not sure it's working 100% tho when i checked, so maybe any apps running off it's readings might be wrong. *guessing*
I read that there isn't a Silverlight API for the compass yet, hence no apps.
*#0*# from the Diagnosis app takes you to the LCD Test screen where there is a Compass tile, which gives you a functioning compass

Makes sence, Call me silly, but which way up is best for the compass, Flat on phones back, Or Back of phone Facing away from me.
As i seem to get two diffrent readings and havn't got a "normal" compass to compare too.
Having the phone horizontal will give you the best results - if you just rotate your position, the needle should point in the same direction. I've tried it in two locations and it seems accurate enough

Note to self *test outdoors before saying anything again about compass *
Thanks for the *#0*# trick - works fine, so it's just the apps that don't work as is suggested above.

[OFFTOPIC] all irrelevant topic spam, trolls, unecessary comments, etc... moved here

that doesn't make any sense at all, the phones screens are super strong and anti scratch out of the box from factory without any add-on.
if you cracked yours like you described, you must to have put it over a very hot surface, or with saline/acidic solution.
i've seen the video where the guy repeatedly intentionally drop the screen with no problem, until he tried to smash it over 1.5m high, anything less than 1.0 drop is safe for the screen.
i can see why samsung doesn't believe you, as it's physically imposible for it to break in the way you described it.
all that aside, if you can find a replacement screen, usually it is a plug and play piece.
i've done many of those on my old Treo and Blackberry phones, the SGS will be no different.
Replying to AllGamer's post. I had just taken my galaxy off my battery charger. So the phone was pretty hot. I believe that there was some defect or tension on the screen. The cracking started from the corner of home button.

Im not sure about this.
My 2 weeks old phone dropped from the sofa and down at the floor today. About 50 cm and landed flat on the floor with the front first. Screen cracked all over, phone still usable though.
I´m ordering a replacement package. To much hassle trying to arguing against samsung or the shop i bought the phone in, stating the same as a bow.
But the lesson is, be careful people. The screen cracks surprisingly easy.

Actually I can't find any decent quotable source. That said I may be slightly embarrassed as I come up with this:
What is MS-Assisted mode of operation?
In MS-Assisted mode, the network elements calculate the location of the device. This mode is suitable for one-shot fixes, wherein the location does not need to be updated frequently.
Back To Top
What is MS-Based mode of operation?
In MS-Based mode, the network provides the satellite information to the device, based on a rough estimate of where the device is located, and the device acquires the GPS signals from the satellites and calculates its location. After the initial fix, the device operates like an autonomous GPS receiver, until the satellite information must be refreshed, at which time the device goes back to the network to update the satellite information. MS-Based mode is appropriate for applications that require the device location to be updated rapidly, such as a navigation application.
Back to the OP again.....

If you don't have corrective information, just P*SS OFF...
You've trolled every GPS related thread out there, with no information what so ever and only whinning about how your life sucks without GPS... I guess you must be hitting the walls in your place without a descent GPS eh?
It is specified by the OP that he "assumes" it stands for X and Y. This is speculative but still, this is at least someone trying to DO SOMETHING else than whine pointlessly and troll everything...
What did you do to make it right? Did you concact your reseller, did you contact samsung, did you tip any news site with the information?
As for the informations, this is what MS stands for:
MS = Mobile Station = your cell phone or handheld
MS-based = it gets GPS information assistance to find the satellites, then continues calculations on its own. Used for example with VZ Navigator.
MS-assisted = gets GPS assistance, and then sends raw GPS readings to another server to do the location calculations. Used a lot for E911 locating.

Yesterday my GPS started going totally berserk on me... I usually have a good track, better than I used to have with my HTC Vogue to track my workout but wierd thing appened yesterday, got me this track:
http://sportypal.com/Workouts/Details/776945?key=121d6fcdae3e1f2a69d349083a6f18affae9cd0a&ms=0
So I've disabled WiFi, rebooted the thing and it was still inacurate...
http://sportypal.com/Workouts/Details/776280?key=f7ae25b101afde4752bfd15d940e289ef8c4b8c4&ms=0
Better still, but unusable to track jogs
So I went ahead and strted GPS Status to clear and redownload A-GPS data and did a small test
http://www.google.com/maps/ms?ie=UT....436748,-71.004682&spn=0.005479,0.013894&z=17
I've played around in here and crossed the street a couples of times... I would say it's within 2 meter accurate of my real position and no weird jumps...
Still, this was a small 5 min. test. I'll check it out when I get another jog but it seems like the fix was more stable.
I know AGps is only used for the first fix, and shouldn't affect the accuracy once fixed, but what if (this is speculation, it should need further investigation) the GPS status accuracy issue was more likely caused by a lost and retreival of a fix? In this case, the fact that the fix was lost/regain would mean that the aGPS would affect the accuracy as it is constatly regained.
Any way to force disable the AGps overall?
It wouldn't be folish to belive that Samsungs engineers used MS for another meaning, they're often not very good in English.
I'm curious of the possible effects of moving the internal GPS antenna. Aka opening the phone, moving the antenna far away from other components and testing the GPS with default settings. Sometimes does wonder.

That doesn't mean that the OP settings don't work best on our phones in real world testing. Has anyone proved which setting is best?
MS-Based = Mobile Station Based.
MS-Assisted = Mobile Station Assisted.
Standalone = no A-GPS used at all?
From this page, we can see that "Mobile Station" (MS), refers to the GPS receiver, ie the phone itself in this case. Therefore MS-Based means the phone itself computes the location with a combination of data from the GPS signals and the A-GPS server. MS-Assisted, means the phone sends it's GPS data to the server for the server to calculate the location for it. Standalone presumably means that the phone doesn't ask the servers opinion (is that correct?)
The point is that the OP was running a series of guesses based upon their experience of testing the device in the real world and trying to make sense of the data they saw. Therefore unencumbered by ideas of which should be "better" they have gone purely on test data. This might go against knowledgeable instincts, but doesn't mean it is wrong... even if the explanations of "why" are miles off!
If you have something to offer, then please DO carry on reading past the bit that was wrong, and see the bigger picture. Do the settings mentioned help or not?
I seem to remember that my phone was set to standalone when I got it, and someone trying to help suggested I switch to MS-Based, which I did, but I've had problems since then. I'll try it back on Standalone for a while and see if it helps! Maybe the A-GPS stuff is still part of the problem on this unit, and it performs better in standard GPS mode? Or maybe we can find a better server to use for the assistance?

Hey, I actually published a track showing how the GPS performs well when used in open spaces, and awfully when it's sorrounded by stuff like buildings.
I guess that's more helpful for investigation pourposes than blaming the world for not being alligned with the Galaxy S' GPS, as others do. XD
No offence, but all this thing about recording tracks and looking for miracolous configs is starting to be ridiculous. You might notice slight improvement by doing so. But it won't be enough.
So, sorry for bringing people's hopes down, but if the GPS could be fixed by simply changing some settings Samsung would have already done that. You know, even their useless engineers could be able to do that in 6 months time.
I'm going to come to maesebit's defence. I was talking arse about MS nav and he called me on it. The wandering behaviour which I had put down to INS could easily be caused by having a base-station try to DF you and pass that position back (doppler shift maybe? That would explain why it keeps you moving for a while until it decides that you have stopped.)
Actually it doesn't make any difference. The loudest cry in this forum seems to be for 'MS-Assisted' which is precisely the wrong mode.
They're not well named modes, given that MS-Based is actually assistive while MS-Assisted is actually based - quite counter intuitive!
I know it's cheeky but I'm going to keep ammending the OP because I think it's important that that paints a picture of what can be done. Simply put I'm under no illusions that Samsung will do anything about this because it needs a hardware fix so it's for us to look at the 'art of the possible'.

MS- Based and MS-Assisted is standard tech slang. But who know. They could be changing the achronyms meanings. Maybe they could be using "GPS" as "Great Piece of ****" instead of "Global Positioning System" too.
As of changing the antenna placement. That'd be interesting. Anyone dares to give it a try? We could also try to attach an external GPS antenna to the phone and see what happens.

I would agree with you, but considering some have good tracks, some have bad tracks; there must be something that affects the GPS usability.
And, as I replied, A-Gps will have an effect if the signal is constantly lost and regain, as it is most likely the case in urban area, where the signal is known to bounce off of buildings or be disrupted by radio signals in the surroundings. I don't know how much you've tested any settings at all, but considering most of your answers consist in discrediting the whole A-Gps theories, I would assume “none”. So, your “theory” that it doesn’t affect anything at all is still a theory, just as OP’s or any of us.

I don't think so. We all would like to believe that the Samsung engineers are as involved as the XDA crowd is. Forget it. Why did it took months for Samsung to come up with their Froyo version? Look at it, what's are the extras that Samsung puts in Froyo that legitimate months of delay?
Samsung just sees this as a calculated risk:
- only 25% of the customers will use the GPS
- 25% of those will have used a GPS phone before and are able to compare
- 25% of those will bother
- 25% of those will look at forums like XDA
- 25% of those will rant on forums like XDA
So, 0,098 % of customers will have a problem, big deal. Samsung just doesn't bother. Maybe a few engineers do, but they are already working on the Galaxy S2, and we are blessed with people like the OP to help us out.
I have a Samsung Blue Ray Player also. The thing has a RJ-45 network socket. To this day, it's unable to find Windows Network shares in the network (you know those shares invented in the Windows For Workgroups era). So you can type in the IP adress, username and password manually (painstakingly with the remote) so it finds your shared media. But.., the engineers didn't bother to make the player SAVE that IP, username, passwords when you power off the Blue Ray Player.... That's the level of engineering at Samsung.
PS: my GPS works fine from the start. Fix in a few seconds, and just an occasional hop on a nearby road.

our GPS actually works well
The problem we do have is not really GPS, the root of the problem actually is the shaky compass sensor. With not knowing where exactly north is, the best navigator can't tell you where exactly you are. .

Are you serious? North and South, East and West have never been relevant in determining your GPS position....
Direction is based on the followed track between two or more determined GPS locations, not the poles.
Only a Compass can indicate North when stationary, a GPS device has to be moving (been moving) to indicate North, which it doesn't do based on poles but on the GPS locations it determined in the previous seconds.

A compass isn't involved in traditional plain GPS. Correct.
However, is it definitively proved that the compass doesn't interfere with GPS tracking on our phones, by adding another sensor feed in to the mix?
It probably doesn't have an affect, but are we absolutely sure?
Have people tried re-calibrating their compass and accelerometer, even just so we can dismiss them completely as being not part of the problem?

Compass accuracy?

It seems like my compass is somewhat off. I've downloaded a compass app from the market and used its calibration function several times, but it still seems off. This appears to be somewhat problematic when using google maps 5.0 in compass mode as well, since the actual compass directions don't line up with the calibration of the phone.
What's the most accurate way to calibrate the compass? Is there an app, or some other way, to manually adjust the calibration if its off?
In what way does the compass seem off? I have no problems with the compass on my end.
in maps 5.0, is so OFF!
Tested actually a few hours ago, my compass was like 30 degrees off.

Like the previous poster said...using compass mode in Google Maps 5.0, the direction of the map is off compared to how I'm holding the phone (if that makes sense).
Omg I know what you guys mean in the new maps 5.0 the compass is showing for me that its pointing a couple of degrees to the right. So has anybody figured out how to fix it?
Make sure when you're checking the accuracy of the compass that you are not using it around something that would be causing interference, especially the MyTouch Car Dock that T-Mobile sells. For some reason, that thing causes major interference, and makes my compass think it's 90 degrees off.
... Ironic for a Car Dock designed to help the phone act as a GPS device.

Omnia compass in Mango - total crap?

As many others, I have updated to official Mango yesterday. And i was really surprised by compass - its accuracy is much worse than simply guessing "where the hell could that north be" . Do you experience the same?
Majority of applications I tried required "calibration" - shaking Omnia in 8 shaped movement, but I found this absolutely useless. Even if the pointer is in north-south orientation, it usualy swaps north and south part of the pointer.
I tried:
Compass 7 from Redtalon - points north in 1 from 10 cases, usualy points towards west. Rotating phone makes this absolutely crazy
123 Compass from Agulhas Solutions - sometimes points north, but pointer is shaking as hell, most usual direction is south-west. Rotating your phone means rotating pointer anywhere. No sign of pointing towards north...
Compass from KanzSoft - this one looks to be the most promising. It shows at least basic knowledge where to point, but is oscilating in +- 10°
Maybe I just found wrong applications - do you have any suggestions?
I totally agree...
It sucks and they didn't even implement it in bing maps, that's the only thing I miss from the iPhone.
I tried the first two compass apps and the first one was stuck at north until i shook my phone, the second is not better than the first...
Agreed. My compass is utterly useless.
The compass that is included in the diagnosis app by entering *#0*# works pretty well over here. It does oscillate quite a bit though...
If I understand well the Mango SDK docs, our crap compass doesn't manage to pass the calibration test made by the devs. Only the Compass app from KanzSoft seems to use results even if the sensor is not calibrated.
I'll try to play with the sample as soon as i find so time to.
As far as i'm concerned, I didn't even know that the Omnia7 came with a compass, so it's a good news.
well, not for me - for me, it does not do anything - diag version 0103

Hey.. Remarkable. I tried the app. I won't get passed the calibration. But in the background you see a compass and it's working quite well (best I've seen so far). So if Samsung just fixes this calibration issue, we could actually have a proper working compass on our Omnia7. They fixed a lot of issues in the Mango driver update package. I hope they're gonna fix this one too.
Heathcliff74
Optimus 7 too....
Something, somewhere is completely screwed
Through the engineering menu, compass works fine (a bit jumpy - but at least points to North!)
But...every compass app I've tried points the the wrong way, usually by 10-20 degress
Even the official Scansearch app is ropey - allthough it it does seem to get it right eventually after rotating the phone a few times
(often gets N/S flipped)
Mango RTM + latest firmware (1.0.13.10)
Confirm: mine pointing west too.
how to fix ?
Deleting and reinstalling the diagnosis app made mine run much better.
However, mine is 180 degrees inverted (i.e. North shows as South)....

That was a cheap shot haha...
It more for a stargazing app I use - Skymap... check it out its pretty good... it uses the compass and telemetry data to orientate the map on the screen so it knows where you are looking.
Try Compass VO, it's the most accurate one compare to my actual compass.
It looks like the compass on the Omnia 7 is off by 10* according to Compass VO accuracy fix.

edit: so, compass is confirm to be crap. Rotation is in consistent.
I used to have heading at least in diags, but no more. I've got only those XYZ values. However it doesn't change the fact that I never got trustworthy readout from compass. Sometimes it was correct heading, but I never knew that until I compared it to real compass. And when I turned 90 deg compass heading changed only little bit, like 20 to 40 deg or sometimes it didn't changed at all.
I have to say it's quite disappointing and I'm thinking about trying luck with RMA.
On my Focus, at first all compass apps didn't worked correctly. After I read this diagnose menu, I tried to enter. The XYZ changed as I change my direction, but the compass didn't move at all.
Then I tried the compass app again (from Kantz something), It now pointing in a consistent direction and rotate (keep pointing in the north???) as I rotate my position.
Dunno what really happened here ...
Ok, this is my first post. But I hope this willl help some Omnia 7 owners.
I tried also a lot of compass Apps but without luck. There was no App which showed the correct cardinal direction. Then I read in another Forum someone had reinstalled the diagnostic tool and after that everything was fine. So I tried this also.
And...after the deinstallation of the diagnostic tool the 'My Compass' Apps works perfect. Now the app didn't ask again and again for reinitialization of the compass.
I didn't installed the samsung diagnose tool again and I didn't tried other compass apps but this was for me a first step.

EDIT: Cool! My Reality Scanner in Navigon 4.0 works now too!!

Something else... Calibration!
From this article: http://blogs.microsoft.co.il/blogs/alex_golesh/archive/2011/05/24/windows-phone-mango-what-s-new-new-sensors-amp-tooling-enhancements-part-3-of-8.aspx
In addition, compass sensor enables application to subscribe to the Calibrate event, since magnetometer sensor which used to implement the compass is subject to external interference. Metal obstacles, high-voltage electrical installations and some electronic devices could interfere with Earth’s magnetic field and change the local magnetic field’s values. In case the sensor needs to be calibrated and the compass API fires the Calibrate event. When this event fired the application have to present the UI with instructions to perform sensor calibration. Sensor calibration performed by waving the device in figure 8 pattern.
The API doesn’t provide any “CalibrationComplete” notification, and it is up to developer to decide when data accuracy sufficient to the application. In general, HeadingAccuracy below 10-15 degrees should enough for most applications.

Most compass apps have a calibration function. I couldn't get this to work. Didn't matter how I moved the phone in a "figure 8". Then I tried Youtube and found this video: http://www.youtube.com/watch?v=sP3d00Hr14o. It's for an iPhone, but it works the same. The guy in the video wave just once to calibrate it. I had to do it a few times, but then the app said: Calibration complete!
I now finally have a working, calibrated compass in my Omnia 7!
That also means I can use all apps that need the Mango Motion-sensor. Omnia 7 doesn't have a gyro, but with compass and accelerometer combined you have a fully functional Motion-sensor (although slightly less accurate than newer devices that also have a gyro).

Compass-VO update

Try Compass VO, it's the most accurate one compare to my actual compass.
It looks like the compass on the Omnia 7 is off by 10* according to Compass VO accuracy fix.
edit: so, compass is confirm to be crap. Rotation is in consistent.

Actualy Compass VO works very well on my Omnia 7 .. once the phone digital compass is calibrated (8 shape) I have no issues with rotation, pointing magnetic and geographic north.
I like it because it allows you to set a map (topographic) in the background and use it together with compass to navigate. Not to mention multiple themes + other features ...
Really recomended.
Cheers,

Compass Calibration always off

Hi. My compass is usually up to 90 degrees off.
I can calibrate it with GPS Status, UT it lasts a day or so. In daily life , I have to recalibrate the compass each time I want to use it, which is not very pleasant.
I think I never ever calibrated the compass of my S3.
My firmware is ANE2.
Do you also have this problem and is it fixed in a newer firmware (which I'm not looking forward to use because of towelroot).
thx

GPS should be dead on, even out of the box and unrooted. Never had an issue with it beeing off on the S5. Kompass is good for me, no deviation here. Do you use a (flip) case with metal or magnetic parts in it.
no flip case or anything. my motherboard is the older revision 0.8
Is it really just me? Maybe I have a hardware defect?

I have now my second S 5 and the compass is still off, every time I use it. annoying

Same for me - I buyed phone with this annoying bug. But only in Google maps. If I use anothe maps provider compass is calibrated. I don't understand

It's true, I didn't notice that before. It's just gmaps. If I switch to here maps and then back to gmaps, the compass is ok.
