[Galaxy S II General] JuniorGG:
Mine does the same. Actually I can get even 15 degrees deviation. I noticed that it seems to depend on the location I am, despite apparently there should be no magnetic objects nearby. I am pretty sure that if if you try rotaring your phone at constant angular speed in the horizontal plane (with it horizontal on a table for instance) with a "compass" app running you will notice that the indicaton on the screen speeds up considerably when the phone is pointing to the north, and slows down when is pointing to the south.
[Galaxy S II General] pub00515:
Which Gingerbread version are you guys running?

I'm still waiting for the 2.3.4 update.

It would be interesting if someone could try this with 2.3.4, perhaps it works with the update?

Thanks...

[Galaxy S II General] TML1504:
hi mark,

again, what you (we) experience here has nothing, i repeat nothing, to do with the GYRO. what you mean is the accelero- and magnetometer! a gyro knows nothing about it's current position (it only detects deviations, read about a coriolis vibratory gyro for more details about the mems gyro the sgs2 is using)

most programs i know are not using the gyro for positional information, for example google maps, google sky... they are all using the magnetometer in combination with the accelerometer ONLY!

Hi Markus,

thanks for the heads-up, but I think I have a pretty good idea of what's going on:

Why?

Well, for starters, I'm a software developer in a technical field and I'm also the author of STLView mentioned above. Secondly, the same app running under Honeycomb with an Asus EeePad is working perfectly, and it is using the gyro there. Yes gyro and no, not magnetometer.

The problem with the S2 as I see it, is:

either Gingerbread or Samsung have failed to implement the rotation_vector sensor, as provided by the official API, correctly. On the S2, it is using the acceleration sensor combined with the magnetometer, which is just plain silly, as the magnetometer is too unstable for correct rotation rate measurement. On the EeePad, the same virtual sensor is using the accelerometer and the gyro in combination (gyro for rotation rate and the accelerometer to eliminate gyro drift). What you get is a very accurate sensor reading, which is just not possible on the S2 as of now.

Hopefully, either Samsung or Google are going to fix this flaw, but I think the problem is more on Samsung's side as they are the ones who actually know what physical sensors are available. That's also why it would be interesting to find out if other devices running Gingerbread that have a gyro on board are also experiencing the same problems.

By the way, I'm also a pilot so I think I have a pretty good understanding of what a gyro is and what it measures, thank you very much. Next time, remember: "Halbwissen ist gefährlich" ;)

Regards

Mark
[Galaxy S II General] TML1504:
hi mark,

sorry - i didn't meant to be rude... ;)

nor did i know your background; the thing nowadays is, a hell lot of people are talking technical nonsense all the time, which is quite frustrating...

i have to admit as i'm no software developer i didn't know the thing with the rotation_vector, what's sure for me was that the actual situation is caused from the accel/mag sensor, simply because of its behavior. that it would be way better to use the gyro as well for all this applications is absolutely true.

so let's hope either samsung or google will provide a fix, as you said!

glück ab, gut land! :)

[Galaxy S II General] pub00515:
Hi Markus,

no harm done :)
[Galaxy S II General] htc9420:
I can confirm that also. Sometimes the image on STL View never settles and it's moving even when my phone is on the table.

The thing that they use the magnetometer along accel/gyro is plain wrong. For one reason that is not that reliable as gyro/accel and the magnetic field is not uniform, plus the fact that the magnetometer is triggered by a lot of mag fields- even a plugged wire has a slight electromagnetic field.
[Galaxy S II General] Guiper:
Can somebody try it with CM7?

Here it works pretty good, with no drift at all. I guess the samsung issue may have been fixed in CM7.
[Galaxy S II General] pub00515:
Hi,

that sounds very interesting! Can you please try a simple test:

in STLView, with the gyro button (on the left side) enabled, can you place a magnet next to the phone and move it around and see if anything happens in the viewer?

Thanks!

Mark
[Galaxy S II General] Guiper:
Well I don't have magnets at home but tries a couple of metal objects and can confirm that gyro is working as it should.

My and Coolya we rewrited most of the sensors userspace, from the open source code (mainly nexus S one) , and somehow it was fixed.
[Galaxy S II General] TML1504:
nice find!!

would this be applicable to other roms as cm7 as well?
[Galaxy S II General] pub00515:
This sounds exciting. Forgive me, but I'm not very ROM-savy, what does this mean to users who just stick to official updates?

Thanks

[Galaxy S II General] skibadee:
Just my 2 pence worth

When u calibrate the phone I found u need to do it with the raised bottom sitting over the edge of a table. Otherwise its not flat. Had similar problem with another compass app. Dunno if this helps?
[Galaxy S II General] TML1504:
the issue here has nothing to do with the offset calibration you mentioned, nor does this affect the unstable magnetometer reading (which can be improved by doing the "8 pattern" and rotating the device twice around each axis).

else, the main problem (the missing rotation_vector implementation) is totally unaffected by that, and could/should get properly fixed by samsung (i doubt that google is responsible for a missing implementation on a specific handset)!

hi mark,

this means that you only get the fix IF samsung recognizes the problem, and implements a fix in any of the future roms.

on the other hand we need to know what Guiper exactly did. i'm also no expert, but it sounds as he modified/improved the sensor modules. would be interesting if there are any dependencies (to a specific kernel), if no, a simple replace of the module(s) would be enough!

they are located in /system/lib

libsensoraiding.so

libsensorservice.so

libsensory.so

and /system/lib/hw

sensors.GT-I9100.so

note that you would need a rooted phone for this, because you have to modify the system partition for that. on my hd2 and dhd there was the possibility to put such files in a specific directory on the sd card, and the system will replace the existing files (modules) with the next reboot!

regards,

markus

[Galaxy S II General] fenrasa:
hi,

has someone already tried any other/new firmware for the S2 and can tell us, if rotation_vector is finally implemented correctly? this is a real problem for me.

what about cm7 or other mods, do they go this deep to rewrite the android-os?

greetings,

fenrasa

[edit]

-android api demos (from android dev website)

still using magnet only or sth. anyways, buggy.

how do i get 2.3.4? kies only?

[edit]

what about cm7? anybody willing to risk it?
[Galaxy S II General] dzid_:
So has any workarounds came up? I'm on CheckRom 2.3.6 and the orientation readings are still ****ty. I came from Galaxy S then I bought I S2 and I though finally I've a phone with gyro so orientation can be calculated precisely under dynamic movements. But still only app I find which calculate orientation on its own and using gyro (in some way) is:

-Gyro compass 3d

- 4D compass

-New horizons gyro compass
[Galaxy S II General] Gnarfsan:
A hardware issue sounds likely. There is an actual tiny gyro suspended in a magnetic field inside the chip. Production could easily go wrong.

[HTC Sensation] rydr1:
Look man, they already gave you a solution, PAY FOR THE UNLOCK CODE or CALL T-MOBILE to see if they can give you the unlock code.

It doesn't matter what phone you have if you need a SIM unlock you will need to get it from somewhere because as someone else already stated, at this time there is no way to SIM unlocking the phone with the software that is available to us.

Other members here have you running around because you can not unlock this phone by just changing a ROM, not here and not on this phone.

Don't confuse the spoonfed blackra1n unlock and jailbreak software with something for android.

If you payed over $300 for the phone, you should be able to pay an additional $20 for an unlock code, or if you dont like that, learn the HTC method to unlock the phone.

[HTC Sensation] MohElShafei:
My friend,

I was in your situation 2 weeks ago. I was in USA in a business trip, bought a Sensation from Amazon. The seller said in the advertisement that the phone is Unlocked. But when I returned to my country.. GUESS WHAT .. It was Locked to T-Mobile and the Seller cheated me .. So I stayed 1 month trying everything with no luck.

I called the T-Mobile customer service more than 5 times and finally they told me that they will not do anything as I'm not a T-Mobile customer.

So finally after one month of reading and searching I decided to buy the unlock code .. and honestly it was the easiest solution. I did a very good research among the websites that gave that service and I chose (HTCimeiUnlock.com).

It costs 25$ and takes only 15 minutes to send the unlock code ..

My advice to you is to buy the code and rest your self from suffer .. It will talk a long time before a tool appears that performing this function.

Hope that benefits you.

Mohamed

Hello guys,

I contacted asus UK tech support but they advised to do a factory reset...not of much help so far. I am going to try again later on but i was wondering if any of you has experienced the same. I am not sure this happened with 3.1, i am sure my unit didn't wake up by pressing the keys on 3.1 though.
