Compass workaround for Telus ICS ROM on Tmo T989

If you have the Telus Rom running on your Tmo GSll, I found a compass with an adjustable azimuth that can be manually calibrated to correct for the polarity issue we seem to be having with this setup.
It is in the market (play store) called smart compass. there are several apps by the same developer in a group called smart tools. There are free and paid versions available so cost isn't an issue. I installed a paid one to support the dev. In the settings is an azimuth adjuster (just like a real compass), and I was able to fix the compass for that app. good enough until a permanent solution comes along.

+1 Calibrating fixed it for me as well.

Did not work for me. Calibrated using GPS Status and still getting North as East.

Same thing happened for me as well. The Calibrating didn't seem to work. Maybe I did it wrong? But I tried multiple times with the same result.

The sensor in the phone is backwards. I couldn't calibrate it either. Thats why I suggested this app. It has manual calibration that goes beyond the software limitations of the device. It doesn't fix the phone, but it gives you a working compass until we can figure out the problem with the phone.

It's funny, I just tried this compass and didn't have to configure or calibrate anything. It worked perfectly right away. I am keeping this compass. Only one that has worked correctly so far. Thanks.

[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...

C6502 After Updated 434, Problem Appear

Hi everyone,
After updated to 434 my dial tone disappear and camera focus (the square thingy) does not turn into green to lock the focus, it do nothing when i touch the screen, no focus sound also
Anyone faced the same issue after updating? Hopefully it just a OS bugs.
Does KA06 Xperia ZL Revolution Rom fixed this?
Model : C6502
Baseband : 9x15A-ACEFWMAZQ-30110017-11
Build : 101.A.1.434

Please anyone can confirm this? just want to ensure whether it is a software bug or related with hardware. FYI, i have test harware using *#*#78.....(forgot the code), everything seem to work fine.
This is my newly yesterday bought unit, so i think i can get 1 to 1 replacement if it have any issues.

i have done PC Companion repair feature actually, i think this feature is same like factory reset. Still the problem appear.
I think it is OS bugs.

Problems with some navigational sensors

GPS is really quick to find a fix, but in Google Maps, I keeps wondering randomly. It's not even snapping to roads.It's just floating around some random spaces of land.
My compass doesn't work either. I've tried calibration using GPS Status.
Anyone else have these issues?
Not rooted, everything stock

I do find the gps problem in mine too. For me it even takes time to get the gps locked (~1 min)

I have problems with compass and accelerometer too. They work randomly and they often don't report the right values!

After upgrading firmware(sony official), My compass is now even worse. GPS improved. No problems with accelerometer.

Sad

4.3 is an improvement. You have to calibrate before every use, but it did work for me. I'm back to 4.1 for the battery life and wanting to root.
