Compass super lag

Anyone notice the compass as well as other sensors respond SUPER SLOW. Fire up skymaps and find mars. Go on ill wait... Broken GPS is getting all the talk.

There's an app called "Android Sensor Data" that can calibrate the accelerometer, but you have to run it at every boot. It doesn't fix the compass, which I expect us just broken.

Yup, it was one of the first things I noticed about the phone. The compas is definitely either broken or just not very good.

Its not only sky maps but also layer as well, once you stop moving the phone it takes a good 10 to 15 secs to position itself, very laggy, just patiently waiting for the fix now -_-"

one would think with Samsung preinstalling Layar on the phone the compass would work without a hitch... im hoping its a software issue not updating as frequent.

Based on how a compass works, (magnetism) I would hazard a guess that there is NO software fix. Buy a compass. If it doesn't work, it will never work. Software can't fix a bad magnet. I COULD be wrong...I HOPE I'm wrong...I DOUBT I'm wrong.
Magnets are not software. ):

I asked T-mobile if there would be a fix for the compass along with the GPS on Twitter. This was their reply:
"TMobile_USA: @fjohnette That's what is believed causing the GPS problem so its possible we will keep you updated. ^SG"

So this means it's possible that they will NOT keep you updated??
Anyway, I think we now have the word of every t-mobile CS rep and tech support person and most (if not all) don't really have any idea. I guess it's worth the effort to keep pestering. It'd sure be more comforting to have an official response.

You are completely correct in how a compass works... Basic magnetism... However. Just because our compass doesn't work doesn't mean the magnet bit isn't detecting north as it should. It could easily be that the other sensors that detect which way that magnet is oriented are reporting incorrect data, which is possibly fixable via firmware update. Or that the android itself is doing something wrong with that data, or any combination of the above. And these possible causes are far from exhaustive, just a few possibilities off the top of my head.

Yep, but every single thing about how that data is collected, interpreted, and passed on to the operating system is software, not to mention the interaction with the accelerometer sensors as Arr mentioned. Lots of potential points of failure here that have everything to do with software. Fingers crossed that it's not just a borked magnetometer.

Very true. As I said, I REALLY REALLY HOPE they can fix it... I'm just worried that we're going to be stuck with broken hardware. I'll never buy a phone on launch-day again...

this is my fear as well. It bugs the **** out of me to see people all over the forums violently defending samsung and saying with absolute certainty that a firmware fix is coming.
How do they know it can be fixed with firmware? I'm not saying that it's impossible, I'll be the first to admit I have no idea how the compass actually works, but to post saying that it will be fixed is so unbelievably stupid and irresponsible that I can only attribute it to buyers remorse manifesting itself as post-purchase rationalization.
Too many idiots to have any sort of productive discussion anywhere.

The compass is definitely the one thing that annoys me about this phone. I really like Google Sky Maps and 3D compass and right now they are worthless.

Agreed. The GPS issues are getting so much attention that the borked compass is falling by the wayside. I actually use the compass, so this is really annoying.

you guys are brave
I returned the phone after a few days and decided to wait for a fix.
When/if the fix comes, I can easily buy the phone again.
To keep the phone is the same thing as keeping you anxiety level high, waiting for a fix, checking every board twice a day.
Is it worth it?

Google Sky maps works fine for me. It does lag slightly when rotating, (which seems to match what others are saying about compass lag), but i don't see how it's worthless. It's dead on for me.

Have you tried Google Street View (Compass Mode) or Yelp's 'Monocle' / Layar?
The compass will sometimes point to magnetic North. But most times, it spins around wildly, or simply points to the wrong direction and does not update correctly.

A friend and I bought our phones on the same day. Date on the stickers on the box (which I assume is a build date) is 7/17 on both of them. Side-by-side, Google Sky works perfectly for him, and doesn't work at all for me.
My compass points south no matter what orientation the phone is in, or what direction I face. Sometimes if I just stand still for a very long time, it'll slowly sort of drift in one direction or another, but I haven't had the patience to just wait and see whether it ever actually aligns with where I'm facing or if it's just random variation.

Check my little video on youtube about this issue demonstrating how slow the compass reacts.
YouTube, search for: SvAJrR5Gmy0
or "Samsung Vibrant Compass Issues"
still won't let me post links yet....
I did end up getting the other phone working instead of pointing in only one direction. I factory data reset the phone and tried agan and it started pointing in the correct direction at least, still very slow.
I also suggest looking at sensor data to see how your phone performs:

[Q] calibration g sensor?

Hello.
*update*
after install jm6 on my tab there was a "Horizontal calibration"
install jm6 go setting -> display settings -> horizontal calibration.
Works perfect for me. Now i can play alot of doodle jump
-------------------
My G Sensor on my Tab is really bad..
and i can't play games like Doodle jump..
How can i fix this?
- Maybe with Terninal Emulator?
I talk with Samsung, and they just say that i shall send it to service..
Sorry for poor english.

Hi
I have exaclty same problem, sensor are badly calibrated.
Can t play doodle jump... (I know, life is difficult)
Any idea to calibrate it?
Thank and regards
Matt

Hi,
Try Google Sky in landscape position ;-)
Poor or bad calibration !

Have the same issue. 2 Degrees x, 6 in y direction.
No feedback from Samsung service up to now.

There is a sensor self test - dialpad *#0*#

Thx, but a selfetest does not solve the problem
Calibration would help....
Anyone any idea, someone knows how Samsung would repair this, via Software or do they have to change ´some hardware?!
BR
Peter

My tab also has the g-sensor problem. I tried two tab and both of them has different degree of G-sensor problem, I think the G-sensor problem caused by samsung's inaccurated calibration. I would also want to know the way to calibrate the sensor by myself, anyone can help?

This is the first thing I noticed when I buyed the tab. The gsensor is off, it often changes to landscape or portrait when only a little inclination is given.

Yeah I just download that free 'level bubble' app.
Pitch off by 2 degrees
Tilt off by 4 degrees

Noticed the same on mine. Not a big issue for me. Hopefully it will be addressed

Dicussion today with Samsung Service Hotline,
try full hardware reset, if that does not help send it to repair it.
Tomorrow ill have the chance to talk to a technical guy.
Keep u update.
Peter

Today discussion result.
1.) Wait for software upgrade, known issue, no info for release of new
Software
2.) Exchange Hardware. If lucky new ist ok, if unlucky change again.

Anyhow good info, means no hardware defect.

You can calibrate it with 3d compass apply in the market. It has a calibration option that should work fine.
P.d Samsung service has to be amongst the worst in the world. Will they ever solve anything?

Hey which developer is 3d compass by?
Sent from my SGH-T849

Its probably to calibrate the compass (magnetic North)
I use spirit level plus (by Androidika) which has calibration but only within the app itself which means you place the tab on a level surface and hit the calibration button and it 'zeros' everything out. I doubt it calibrates the internal sensors.

Tried both, but calibration only works inside the app.
Try to get any statement from t-mobile our Samsung on monday
If someone has a solution....

Ok,
finaly T Mobile sent me mail.
Software Update to come, no but no idea when...
In the meantime use "official" Firmware from Samsung and flash it (even if not offered via Kies).
Anyone can tell me what is the latest "official" firmware for European device?
Got already feedback from other user, that with a flashed ??6? version there is a botton to calibrate..
thx

Compass issue question

Hey all.
I did some searching but couldn't find if a resolution has occurred. Has anyone made a fix for the compass being off its axes? I use 3d compass. When I tilt right, the on-screen compass points up. Etc.
I know this was once discussed. Would exchanging it solve that issue?

I believed this issue is with the developer of the software...
software that were made for phone should be updated for tablet & especially Honeycomb ... as the accelerometer/compass is reverse..etc
some appz can run on tablet properly... but it also need to support HC ( not just froyo/Gingerbread only )
there were some games that were like this ( opposite/upside down... ).... dev updated their software and it works fine in tablet

Oh that's great. Is there a good app to test the tablets compass?
It is strange that vendetta online wasn't an app that was playable due to the compass. Seems like that was all the hype for this tablet.

Try gps status in the market! It's free, does good stuff!

GPS status works ok, but remember to calibrate the compass (wave it around in a figure 8) each time you try to use it. GPS essentials does NOT work, the compass is off by 90 degrees.

Anyone got Google Sky Map Working? / Compass issues

Hello everyone.
I was wondering if anyone here has Google Sky Map fully working on a Nexus 7? On my N7 this app never points me to South - I am always stuck between West - North - East. When I try to point it to south I always get north instead.
I've also verified the behavior with a compass app. If I place my N7 flat on a table the compass is working well, but if I am holding it in my hands right in front of me (USB connector pointing to the ground) I get the same behavior as in Sky Map (south=north, north=north).
Is the compass even supposed to work when holding the tablet with the USB connector pointing to the ground?
Edit: I am experiencing this issue in stock 4.1.2 and Paranoid Android 2.20
Thanks in advance,
mcsmart

My Samsung Nexus S has exactly the same. It's a hardware problem

Hey bro try using the app space junk I have it on my NEXUS7 with no problems at all and in my opinion it's far better GOD BLESS YOU

Thanks for the hints, guys.
I managed to get it working: all I did was calibrate the compass with GPS Status. I never thought this could make a difference, but it did. Cool. I'm glad my N7 is not one of those devices with broken sensors

[Q] Compass not working

My Nexus 4's compass is only pointing south. It shifts slightly to the east/west when I turn but doesn't move very much. I've made sure that there is no magnetic interference around, took the bumper off, and have tried several reboots. I noticed this a few days ago in the Ingress app, and confirmed the issue with a compass app. I am running the stock ROM (rooted) on the latest version of Jelly Bean (JWR66Y). I suspect it may be a bug in the software because my sister (in a completely different part of the world) is reporting that her compass is also stuck on south on her Nexus 4 (also stock but not rooted). I suppose it is possible that we both have faulty compass sensors, but since this is a recent issue that I only noticed sometime after the recent Jelly Bean update, I was wondering if others were experiencing this issue as well. Thank you for your responses and potential solutions.

Have you tried calibrating it? Hold your phone in your hand and make figure 8s with your wrist. I have no clue what that's supposed to look like though
