Guide: How to calibrate the compass - Android General

Calibrate Compass
1. Try to stay away from magnetic fields as far as you can
2. Open GPS Essentials and tap on compass (calibration will not work when the compass is not showing)
3. Put the phone on a flat surface with the display pointing up
4. Move the phone slowly, 5 seconds per full rotation is ok
5. Rotate the phone three full cycles around the axis pointing upward
6. Rotate the phone three full cycles around the axis pointing away from you
7. Rotate the phone three full cycles around the axis pointing right
8. The direction of rotation doesn't matter
Here is a Youtube video to show you how it works.
There are other methods, like the 8-pattern, that are easier and might also calibrate the compass. Watch this Youtube video to find out how.
I was having navigation and compass problems with my new GT-I9001, searched the google but did not find anything to help me. Yesterday I installed GPS Essentials app and there was a Calibrate Compass link. Here it is, copied from my app GPS Essentials.

seem to work for my cell phone. But my Nexus 10, nope. It point correct once, and than it easily go off again.
tried it without the cover too, there is a magnet on the cover to turn off the screen when it's closed. I don't wear watches or anything metal, unless my body magnetic field affect it.
my cell phone, I didn't install GPS essential and the calibration seem to work just fine. I have an old school magnet compass to check.

Thanks it worked perfectly on my OPO.

NO DUDE! DIDN'T WORK!
Your instructions are too brief and vague.
You don't even mention what to click/press!

App to calibrate the orientation sensors?

Mine seems to be really sensitive so that the screen rotates even if I tilt the phone a small amount. Is there any way to fine-tune it?

Wondering this also since I noticed there is no calibration for it in CM6.
Don't know about on CM6 but on other roms, go to Settings > Display > G-Sensor calibration.
Anyway to do this on non-rooted phones? Ever since I upgraded to Froyo it seems to rotate if I tilt it even just slightly off it's axis
Those directions were for rooted and non rooted phones...

Turn off garbage rotation with Switchpro
Anyone gotten a reply from Cyanogen? I messaged him on Twitter, but he never responded.
If you download, GPS Status from the market and in settings under " Help and release notes " it says this...........
My compass points to the wrong direction or I'm asked to calibrate my compass. What should I do?
Your phone contains a digital compass which measures the magnetic field's strength in three direction with three separate sensors. The orientation of your phone is calculated from these values. Unfortunately the sensitivity of the sensors are a little different. To correctly calculate your orientation your phone must measure first these differences. This is done during the calibration process. To calibrate your phone, simply find a space where no external magnetic field is present (preferable outside of buildings) and rotate your phone 1-2 times on EACH of its three axes (Swinging your phone in big 8s in all direction will also do, but it' less scientifically correct ). If you feel that your compass has become inaccurate you can repeat this procedure.
But i dunno if it works or not..

That just calibrates the compass.

Compass Problem

A few days ago I realized that my compass suddenly stopped working correctly. No matter how often I restart or calibrate the phone, I can't get it back to work. If I don't move, it points to wrong direction and then slowly turns clockwise. If I move, the compass turns correctly, but always pointing to a wrong direction. Different apps show that the magnetic field strength is 429µT, as if there was a strong magnet nearby. Normally, it should be around 50µT, I suppose. I don't use any case or something that would interfere. Tried it inside the house and outside at different locations. System is completely stock 4.4.2. Any ideas?

Compass resetting

Does anyone ever have the issue of the compass always pointing in the wrong direction?
I've done manual sensor calibration by going into the service menu (*#0*#, Sensor) quite a few times but the compass always resets.

Probably would have been best to not start a new thread for this since you already commented in another one.
My compass is still fine and working properly from my one calibration from the other thread. Are you getting the blue compass line with a "3" next to it?
I had the "3" and blue line. It was pointing to the true North after calibration. Then it lost the calibration. I've since recalibrated it.
I'm keeping an eye out on this. Will monitor it.
So after a few weeks of testing, I've concluded that the compass resets every time I reboot my phone. This happens consistently without fail.
The fix for me is to do a calibration every time I reboot the phone - this means "twirling" my phone in a circular motion (it's faster than doing the separate axis calibration). Usually this will recalibrate my phone in under 10 "twirls".
I guess it's something to do with the compass not being able to store the calibration permanently. Perhaps it's a R/W permissions issue. I'm on stock Three UK firmware, not rooted.

Compass on Shield Tablet K1: not working properly, but can it?

I have a Shield Tablet K1. I cannot get the compass to work properly.
I have tried everything: Lollipop, Marshmallow, nothing works.
More often than not the compass is stuck, or -when the needle seems to move freely- it gives false headings, sometimes 50 degrees off, usually when pointing North or South.. I have tried calibrating several times, using several apps, as requested. Doesn't work.
My theory is that the Shield Tablet K1 cannot have a working compass, because of the built-in powerfull magnets: two woofers and the attachment for the optional cover on the left side. Try holding a knife to the tablet's back, and you'll know what I mean.
To summarize: The Shield tablet's compass function should have been disabled in stock rom. Does anyone agree?
Agree
I had the same issue, but I did sort it out. I just removed the case, the genuine one uses magnets to latch to the frame of the tablet making the compass crazy. Remove any magnetic case, restart the table, recalibrate. Once you put your case back.... no, It will be crazy again.

Yeah, I think you might be right. If I open up the "Smart Tools" app with its compass, it also has a magnetometer reading, and the reading is always very high.
If I use the Case I have, which has magnets and position it on an angel at the back, the magnetic readings can come down closer to zero. When they do come done to that lower figure the compass seems to start working.
Agreed.

GPS lock

I'm having an issue where it takes fund minutes to lock location on the phone. The problem is most noticeable on Waze. I turn Waze on every time I get in the car (the speed traps alone are worth it), and sometimes it's half my trip before it locks on.
The location is set to high accuracy, and it does eventually lock on. My 6p would lock on in one second.
Anyone else? Thanks

I've seen issues in Waze as well, with both GPS lock and the Compas going screwy...
Have you guys tried running gps status or gps toolbox?
What settings do you have selected in location settings?
On my v10 if I enable the additional low power Qualcomm IZat location estimation option, gps runs all screwy.
Id like to know if gps is hit or miss, as its another of the main features I need and use on a daily basis, along with Ok Google..
My Pixel is now locking GPS in a few seconds after I open Waze. Probably even faster than my 6P.
For anyone else having these problems, here are all the steps I did (not sure which if any of these actually solved the problem)
1. Uninstalled Waze. Turned off Location. Rebooted into Safe Mode (Long Press "Power Off")
2. Once in Safe Mode, turn location back on, open Google Maps outside, let GPS lock (that time still took a while) and use navigation for a while
3. Rebooted the phone again into safe mode. reopened Google Maps and let GPS lock on
4. Rebooted the phone normally, open Goolge Maps first to make sure GPS was working. Then installed Waze
It's been working pretty well for the past few days.
I'm still seeing issues with the compass, I get a GPS lock quickly, but it always shows I'm pointing 100-160 degrees off from my actual heading. Tried using GPS status to calibrate, it now says I'm calibrated, but I still see the issue, even in GPS Status.The compass points in one direction, then once I start moving, the GPS corrects the heading to my actual direction...
I've never had this issue with any other phone, very frustrating.
