Anyone have anything to offer on compass calibration?
I noticed the compass was off in a couple map apps and compass app, always with the same bias (about 18-20 degrees CCW).
Searching Play Store for "calibrate compass", I found a decent compass app (RHB) with a calibrate mode, instructing to do the figure-8 to calibrate. Didn't really work, would not indicate calibration complete.
Found a different app (GPS Status) with a calibrate compass mode that has instructions on how to do it correctly: Rotate 1-2 times around each axis (3 axes) in calibrate mode. This works. Turns out this 3-axis calibration also works for the other compass app too - using the 3-axis calibration method, it indicates " complete " and the compass is calibrated.
I'm wondering if this is something that will have to be done again after every reboot, and/or every time I use something that uses the built-in compass hardware (magnetometer). Or does this in-app calibration calibrate in some way that stores calibration offsets in a lower-level place (OS, hardware, ?) so that calibration persists across reboots and is always there for any app. After rebooting and letting the phone sit overnight, the calibration may have drifted a few degrees, but I wasn't sure because I checked it in a different location.
Interestingly, another recently released Android phone (Kyocera Hydro Wave) that I checked had the exact same (uncalibrated) compass bias as the XT1575, off by the same 18-20 degrees CCW. Makes me wonder if they both use the same magnetometer component(s), from the same source.
Any info would be appreciated...
Gps status & toolbox is what I use on all my families devices and works perfect,. Once I calibrate my compass from then on when I open gps status & toolbox in just a lil bit it will auto set north. Great app called gps status & toolbox in play store and if you don't like ads get the pro key...

I think I may be having problems with the compass on my Aria. On all apps I've used that utilize the digital compass (sky map, compass, AR apps like wayfinder nyc), the compass movement seems jumpy and will give extremely inconsistent results, most times settling on an inconsistent heading.
Is there some way to check that the compass is properly calibrated?
Has anyone else been having problems?
Sent from my HTC Aria using XDA app
I very much have the same problem. Skymap and compass apps are incredibly underwhelming
Same here, skymap is basically unusable.
update:
Figured out a pretty good way to calibrate it. Launch skymap, then rotate the phone around several times on every axis (ie, rotate around x axis a few times, then y, then z). The magnetometer should reset itself and point in the correct direction.
update2:
After playing around with it for a while, I noticed that there is a difference of about 5-10 degrees between north in landscape mode and north in portrait mode. Pretty disappointing and lesson learned - don't rely on your Aria if you're going to Man vs. Wild it in the jungle for a while.
As with all digital compasses, it needs calibration, rather some sort of reset.. I haven't see true calibration.
See this video on it.. It's very simple to do. http://www.youtube.com/watch?v=sP3d00Hr14o
No, it's jot a joke. Compare against a real compass. Without this, I've found my N1 20+ degrees off, after, +/- 2
When i had the backflip you could go into the settings and click on compass calibration, you have to rotate/spin the phone on all it's axis or just do a figure 8 in the air with the phone. I did this yesterday on my Aria on google skymap, told me the sun was underground so I did a figure 8 to calibrate the compass and then it was all good. Just do it when you open any compass using app when you launch it.
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.
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.
Hi All,
Have you tried compass and level tools among ZTE tools? First of all I waved 8 I don't know how many times till it was "calibrated". If it really was. I have doubts because result is far from the accurate. Secondly I tried level tool and spirit level is not needed to say that it shows wrong values. Thirdly camera in manual mod displays a spirit level which also incorrect. Do you have bad or good experiences with these tools? Can anyone know how can level be calibrated?
I have the same problem on my Axon 7. The Y axis is about 5 degrees off.
I can't find any way how to calibrate without root. Did you find a solution or can anyone else help?
Hi,
It looks that compass works correctly more or less. Regarding spirit level. No I haven't got permanent solution. All program can calibrate level. Some of them can store calibration result but of course it isn't effective generally. I tested all sensors with different programs and they seem good. I don't have other A7 so I can compare the values to other brands. Try GPS Status and Toolbox to test sensors.
I worry a bit that VR won't work correctly but I think it will have own calibration method.
Hey all,
Recently got this phone, and I discovered it doesn't have a gyroscope (Kinda took that for granted, should have researched before purchase).
I like to do VR stuff once in a while, so I found the option of using the Xposed module VirtualSensor.
It seems to work, only it's horribly inaccurate. I understand that combining the accelerometer with the compass/magnetometer will never be as accurate as a gyroscope, but I don't think it should be this bad.
I looked further into it, and it appears that my magnetometer is not as accurate as I would like it to be. I found multiple sources that don't even list the compass/magnetometer as a real sensor, is this true?
Anyway, using Sensor Kinetics (app) I monitored the magnetometer (it shows the same behavior using different apps). I wanted to post screenshots but as a new member apparently I can't.
I've calibrated my sensor by using the 8-motion and I measured at different locations, but the z-axis is always weird. There's some sort of disturbance in a pattern, it could be hardware or software. Every second or so there's a significant peak in the z-axis, jumping from -43 microT to -30 microT or even higher. (The magnitude of the graph is of course orientation dependent, but the accuracy shouldn't be this bad). The peaks in the z-axis match up with sudden yanks while using VirtualSensor (my accelerometer is stable).
Could anybody with a P9 Lite please confirm if they have a similar disturbance on their magnetic sensor as well, or do I have a faulty phone?
