Compass weird behaviour. - Focus General

Hey guys
Need your help in here. I have a problem with my Samsung Focus. The compass points south instead of north in every app I've tried, even in diagnosis mode.
The compass is very erratic, moving randomly as I move it with me but always pointing south instead of north. I've tried several hard resets, the 8 figure calibration with no luck at all. I've read some posts regarding this in other forums, but I didn't find any solutions.
Any help will be greatly appreciated

sounds uncalibrated to me. The only compass app I've been able to get to calibrate correctly is the one called simply "compass" by Hani Atassi. I've only tried a few, but of the ones I've tried, it's the only one that actually tells you when it needs calibration... and when you're doing it, it tells you when it's done. I'd imagine there are others but, like I said, I've only tried 3 or 4. The good news is calibration seems to be system wide, so if there's an app you really like, you could calibrate with this one, and then switch to the other.

thanks for the reply. It's not a calibration issue, I've already tried that. I think there's a problem with the drivers or something. Any of you guys having the same problem?

Another GPS Problem Question

Original, I thought I was left out of the GPS problem with the Samsung Vibrant, thinking it was about when you used GPS ...but with the Navigation
However, today, I was using the Google Search function, or something that simply invoked the GPS, but not fully using the Navigation, then it cut out, and I couldn't see anything for about 30 seconds, then it restarted fine.
THAT, please assure me is the problem that people were originally speaking of
I dont mind being wrong about what I thought it was ORIGINALLY. i.e. navigation being used
But please tell me that what I described is the problem and NOT a more serious problem that is gonna involve me having to get a new phone.
I had the NEXUS and one of the 3 I had turned off two or three times a day. They said it was NOT normal, and then I had to replace it..
I am hoping and leaning to believing that this problem is what you all have described as the original GPS problem cutting off
thanks
The original and core problem with the GPS which still exists is that the GPS cannot lock on to more than one or two satellites even though there are many more in view. The result is inaccurate and inconsistent position information being fed into whatever program uses GPS. People will notice symptoms more with nav apps but it will also affect browser location and google search (with location) as well. So your symptoms may be a result of of the common bad GPS problem. Personally I believe that ALL Vibrants have a faulty GPS as I have tried at least a dozen showing the exact same faulty behavior. The best way to determine if your phone has a buggered GPS is to test it using something like GPS Test and see how many satellites lock VS how many are in view (discovered). A fully functioning GPS will lock on no fewer than six sats with nine to fifteen visible.
Thank You XfooYen...and thanks for being Quick
I do not know how to do the test. Might you be able to and have to time to explain how simply and what I need (via apps etc..)
But bottom line, to hear that it is basically, maybe not fully, partly to do with the GPS makes me feel better.
At least it is not cutting off WHEN i am NOT using the GPS, 3-4 times a day, like my first android phone, Nexus
thx
Does the European Galaxy S have this issue? If so, then I fear that a solution is unlikely to be at hand, given that this version has been out for a while, and would point to a design flaw in the hardware that cannot be fixed with software.
That's the big unknown-is it hardware that's defective, bad firmware in the controller for the GPS chip, or a system software problem?
yeah, no one knows if it's firmware or hardware or both. Only time will tell. We all hope it's just firmware.
To OP, you can find GPS Test in the market. There are many ways to see what your GPS is doing exactly. Rather than me explaining it, I recommend you search youtube for examples of GPS testing in action.
A thing to consider is weather you can return the phone with a full refund. If so, I recommend it. You can then wait until a real fix is pushed out and repurchase when it does.
Sent from my Vibrant using XDA app facing north...no, wait. southwest.
Thank you for pointing out where to find the gps test Next i will look into doing it I also appreciate feedback on what the proper could be To summarize it seems like no 1 knows what the problem could be i may know more once the gps test is done next i think most would agree i m not looking for a wii fun on this fabulous phone n next correct me if i am wrong i hope work for t mobile 4 a while and have been there 11 years most phone companies you can't get a full refund out of the buyer's remorse period
i actually believe most of you will think i am right or at least the grateful to want to wait until the problem is saw. It is not the worse in the world once i find out that use it i will wait on the 6 once they say this symptom is clearly not related names if it persists i may ask for a replacement. Until then any support or advice in simple terms, LOL, Would be appreciated. I just saw a thread with the term gps fix with another link does anyone know if that works .
Thanks again so much Please remember this was typed or not typed using the speech to text feature. I have issues that make my hands shake head hurts and issues much better for typing
In sending my last post i head something popped up that said Something beta OR traditional Wouldn't that have something to do with this thread for the entire site on my vibrate

Compass erratic behaviour realised

After trying a lot of the latest builds the only thing I can't seem to get working properly is the compass. It is not smooth and accurate like the like it is in WM.
After trying a few different compass apps I realised what was happening. Rather than using the compass sensor it seems to be using the g sensor. North actually follows the direction of tilt!
Any ideas?

Yes, compass is a bit shaky.
However, it seems to get better when you play around some time with it or move it in a figure 8 pattern.

For me it is not a calabration issue. No matter how many times I figure of 8 it it never calibrates or aknowledges calibration. North exactly matches the direction of tilt every time regardless of the direction I have standing or rotation of the device.
I can't believe no one else has had this issue.
I'm right there with you. I just hadn't realized the strong correlation with tilt. I also feel the 'figure 8' improves the compass, but it is still unusable.
Hopefully, this is enough to make one of the devs look at the compass driver code, slap his/her forehead, change a '3' to '7', submit to git, and we'll all have perfect compasses within 2 days.
Here's to hopin' !
This might help. Quote is Hastarin's.
NOTE: To get your compass working with r7+ you may need to do the following via adb shell (or GScript Lite), you will need to su:
killall akmd
mv /data/misc/AK8973Prms.txt /data/misc/AK8973Prms.bak
Then restart your phone.
If calibrated g by mistake:

I think this is on the right lines as the g sensor calibration fix seems to be related.
A couple of days back I nievely calibrated the g sensor. Realising my mistake I looked for the fix. I applied it and it worked. Yesterday I downloaded an app which had a feature that used the compass and it seemed to be working ok. I tried a compass app and low and behold it seemed to be accurate and no tilt behaviour.
Then just out of curiousity I tried to calibrate it and not only would it not aknowledge a calibration the the tilt behavior returned.
I did not try the g sensor reset fix again but I did reboot the phone and calibrate the compass in WM. Booting back into droid I found it was working again!
Interesting?
There is definitely some correlation between the compass and the g sensor and calibration of either.

How To: Froyo Compass fix

Credit to: abrognlie for pointing this out here: http://forum.xda-developers.com/showpost.php?p=11552644&postcount=163
Figured this would be easier to find in searchs.
Problem: Your compass is backwards and overly erractic and inaccurate.
Solution: Upside down horizontal calibration
How: Plant the phone on a flat surface upside down. A low ceiling, top of a door frame etc. Make sure it's flat and facing upside down. Go to: Settings, Display, Horizontal calibration and calibrate it upside down.
Bingo bango, your broken compass should be fixed. This also cures slow auto rotation
Just tried that. Still as erratic and jumpy as ever.

Hardware problem?
The first time I used Google Maps with EB13 it told me that the compass needed to be calibrated and to move the phone several times in a figure 8 manner. I did it, and the compass has been fine. I'd never seen that before. I hadn't used the compass at all before this, so I don't know if it "fixed" a problem or if I just didn't have a problem, but I thought I'd throw it out there for people who are having problems.

Same for me but it was still broken. X-Plane was unplayable, auto rotation was slow and sometimes unresponsive because the compass was backwards and jumping direction erratically. (download a compass app and check yours) North was south, etc.
The upside down trick 100% cured the issue. Not the figure 8 or the right side up calibration.
*shrug*
Wow! Best find ever! The upsides down calibration worked for my slow gsensor lanscape bug! All this time, rooted was needed for the
"system/bin/sensorcalibutil_yamaha" code to work! Very nice!
I wish I could claim credit for this (the member who deserves all the credit is styles420), and I wish it worked for everyone, but someone found this back when DK28 first leaked. It seems to help with a group of us with sensor data that gets mapped backwards during the flash. It shows up in the compass or google sky maps, but it seems to be a problem with the g-sensors that affects how the compass works.

try downloading GPS Status from the market. Open it and do the calibration tools. Should fix this. Also may improve your GPS (if it isn't doing well)
Possible, but it was the same on my previous epic. I haven't put too much effort into it since I don't really need a compass very often, but it would be nice to have it work for once.

I already have GPS Status. I did that calibration from that again, and it is still messed up. It jumps a little less, but I can turn the phone 90 degrees and the compass rotates 180. Then I turn the compass 90 degrees the same direction, and the compass jumps backwards 90 degrees. I'm having a really hard time figuring out a reason for the pattern. I might have to sit down and draw some compass diagrams.
Worked for me. Fixed slow auto rotate as well

tried all solutions here. no joy
Another issue, maybe?
I wonder if there might be an underlying issue here...
Was doing some research on why my battery life is garbage after EB13.
I hit on this thread because it looks like the compass sensor is consuming a ridiculous amount of CPU... I mean, foregrounded using 7% CPU when nothing else is going on.. like, no compass app or maps being used.
With my Epic pretty much quiescent, top consistently reports it (/system/bin/sensorserver_yamaha) as the highest user. Under DI18, it never even cracked the top ten.
Samsung Epic (EB13 Official) + Clockwork
wow thanks for the tip! i almost returned my epic because of this.
Amazing... how you found this out is beyond me, but it works!

Found EASY gps fix

so as many of us here i had the gps problem, and i started to not care anymore. The other day after i flashed Trigger 3.2, i also flashed some useful apps like SGS tool, spare parts etc. As i was going over those apps, i went to SGS tools, and noticed GPS fix all the way at the bottom. I decided to give it a try but didnt think it would work. I clicked and then select north-america.... and apply.
And surprisingly my GPS has been working perfectly fine since then.
So those of you who still have gps problem, try that
Hope this help

This has been posted before, it works for some people and it doesn't for others. Just like every other GPS fix out there. Not trying to be rude and I'm sure everyone appreciates you trying to help, but duplicate threads just create clutter. Once again I am not trying to be rude so please do not take it that way.
flashing the S.gps is the easiest way as I know
This is kind of random, but did anyone notice that the latest Kies update fixes/helps GPS?
With KA6, I have to manually set GPS mode to MS-Based and change the supl settings before I get a quick lock. With KB5, it works very well right out of the box. No configuration needed.
ooooohhhh

Quick question re Accelerometer

Good day XDA. I just noticed that my N7 is having problems with its accelerometer. I was playing temple run and mutant road kill and the characters always veer to the right.
Question is: is this a software or a hardware issue?
also, is there a fix/app if this is indeed a software issue?
thanks
well, i know that there is apps for calibrate the accelerometer, i can´t remember now the name, sorry, but i´m sure that you can find it on the market o google.
Anyways, did you try in diferents places? i mean, maybe the surface where you try wasn´t flat...
thanks for the reply man.. anyway, i already found a way to fix it and it's been holding up.

What did you do to fix the issue?
Sent from my Paranoid Nexus 7
well first you have to confirm that you indeed have the gyro/accelerometer problem. you guys could download an app for that (i used Android Sensor Box). once that is confirmed, download the app "GPS Status". Run it and go to tools, then calibrate pitch and roll and just follow the instructions. I suggest you guys do this while your device is lying flat on a surface.
after trying this fix, i uninstalled GPS Status, rebooted my device and it held up. played temple run and the character started right smack in the middle lol. also tried checking the sensors using Android Sensor Box and it was calibrated. i just reinstalled GPS Sensor just in case i might need it down the road but im hoping this fix will be permanent. if it isnt, im pretty sure that this is a software problem and an update could give a permanent solution.
let me know if you guys get the same result i had with this.
Thanks

This didn't do the thIng for me neither
But I did the job like this.
Open an app that uses the compass. You can use GPS Status, Android Sensor Box or whatever app you like that uses a compass.
twist/turn your device 3 times around each of all the three axes
FINISH
Even after a reboot it works great.
But if you flash a new rom this fix will be broken
