Rotate Sensor & g-sensor operate in reverse (7.1-r1)

[Zero]

Hi Everyone,
I been testing android-x86_64-7.1-r1 on three of my PC tablets (Samsung Ativ 700t Pro, Vaio-Z Canvas, Porsche Design Book one), the screen is automatically rotated 180 degrees in reverse whether viewing the tablet on landscape or portrait, picture is always backwards; also tested some g-sensor games like riptide, g-sensor is also operating in reverse, i tilt right and it goes left, tilt left and it goes right.

This happens on all my 3 PC tablets, this never happened on previous versions, does anyone have a solution or can kindly help me with this?

[n00bile erasmus]

hp pavilion x2 detachable 12-b020nr

i installed the 32bit version first and no rotation at all. then i installed the 64bit and rotate and g-sensor are in reverse. tried adding hal_sensors=true in init.sh, but it didn't work.

*HPPAVILION*)
hal_sensors=true

[Chih-Wei Huang]

That means you are lucky. :)
The new sensors hal works for you.
But you need to reverse the orientation.

You may need some of these properties.
Try these commands: (via root)

setprop ro.iio.accel.x.opt_scale -1
setprop ro.iio.accel.y.opt_scale -1
setprop ro.iio.accel.z.opt_scale -1
stop; start

If they works, tell me your product id by
the following command. I'll add it next release.

cat /sys/class/dmi/id/uevent

chih-Wei,

Thank you very much for the provided steps and all the effort on Android x86.
The auto-rotation works great on my elitebook x360 1030 G2 after entering the above commands.

Chih-Wei,
Thanks for help, your method did work on my 3 PC tablets, rotating & gyro sensors worked correctly in the x64 version after entering commands, although I have to enter the commands every time i reboot the device, does not save.
n00bile eramus is correct, the sensors do not work at all on my PC tablets using the x86 version.

Thank you for the report.

It seems more devices need to reverse the orientation.
So I just changed the default orientation.

You can download the cm-x86 14.1-r1 to test.

Confirming CM14.1 x64 bit has fixed reverse rotation on my 3 PC tablets, not only that, but has fixed my sound issue & corrected Bluetooth from turning on & off, giving me a stable Bluetooth connection.
this update has made android run just smooth as 4.4r3 through 6.0r3 did on my devices. I will try 32-bit version tomorrow.

[Wing Chun Lau]

Rotation does not work out of the box for lineage os 14.1 on my laptop (HP Elitebook x360) even when auto-rotation is enabled. The accelerometer does not seem to have any effect even if I change the device's orientation. Any idea?

[Wing Chun Lau]

As an update, i found it works fine after reinstalling and no reversal of rotation at all :)

Which version shows reversed g-sensor input?
7.1-r1 or cm-14.1-r1?
Note they have opposite input.

The coming 7.1-r2 will follow cm-14.1-r1.
So please confirm which one is correct for you.

[Alan Weinstock]

Apologies for not mentioning, 7.1-r1 is the one I'm using that has reversed input

Then you can try cm-14.1-r1 which should be normal
on your device.

The coming 7.1-r2 will be aligned with the change
of cm-14.1-r1.

Ah..! I'm surprised the link was wrong that I didn't notice
and you are the first guy found it after two months of release...

The correct link is

So you need to reverse 3 axis. Right?
Try this patch:

You can modify /etc/init.sh directly
if it's read-write mode.

[Nebudte Zvedy]

Sorry too much Linux terminal magic for me..

  What is command which exactly i should run? Its unclear for me from the post.

  Second solution is say me, what text is should replace by using some text editor.

[Chih-Wei Huang]

The patch means to insert the 4 lines (+ means insert) to
function init_hal_sensors() (about line 264...) of /etc/init.sh

[Nebudte Zvedy]

Thx, now its working.

[Nebudte Zvedy]

Hmm, i still have still problem, when i slightly tilt device its upside-down and i cant force it back.. There is more thing wrong with sensor settings..

I upgraded 7.1r1 to 7.1r2 and now it seems to be ok.

Oh... Last time I asked

"Did you mean 7.1-r1 is ok for you but 7.1-r2 is bad?"

You said "Exactly."
I'm a little confused.

Could you confirm which one is good and which one is bad?

[NebudZvedy Zvedy]

7.1r1 - its bad, even with patched init.sh

7.1r2  - its ok, i dunno if is init.sh rewrited during upgrade

setprop ro.hardware.sensors iio-old

or change hal_sensors=iio to hal_sensors=iio-old
in /etc/init.sh.

[Chih-Wei Huang]

I think I was misled by your accel matrix.

(are you sure that's the correct variable you set?)

If 7.1-r1 does work, what you need is to revert 3 axes:

set_property ro.iio.accel.x.opt_scale -1

set_property ro.iio.accel.y.opt_scale -1

set_property ro.iio.accel.z.opt_scale -1

(Not sure if you really need to revert z axis. You should check it by a sensors testing app.)

[Yu Zhao]

Oh, Sorry.  it is not 7.1-r1  , it is 7.1rc1 (CM-x86 14.1-rc1) workd

looks like sensor has no data , But I found 

/sys/bus/iio/devices/iio:device0/in_accel_x_raw

/sys/bus/iio/devices/iio:device0/in_accel_y_raw

/sys/bus/iio/devices/iio:device0/in_accel_z_raw

both have data and change with time

But I don't know why APP can't use this data.

Good. But I still suggest you study
how to make new iio HAL work.
It should be better than the old one.

Besides, I suggest you use a sensors testing app
to test it, e.g., Physics Toolbox Sensor Suite.
It will show you exact values read from the sensors HAL.

thanks for your advice , but my aim is only to make this sensor work.
And now screen rotation can always work , but sensor test APP rarely can get X,Y,Z value. (maybe only on cold boot or rebuild cache? delete APP cache can't solve problem...) (using iio-old)

If iio-old just work, what you need is for new iio HAL
is ro.iio.accel.y.opt_scale=-1
(like ASUS T100)

Try the patch:

Hi Chih-Wei,

I decided temporarily use iio-old to make it work,and i have make a patch for it (tested on CM 14.1- r2)

When I have more time to test,I will try to use new iio HAL

I've tried to use:

It restarts but portrait reversed also

I tried setprop ro.iio.accel.x.opt_scale -1

It's unusual. Have you tried again?
(after set both properties)

What's getprop ro.hardware.sensors ?

Which android-x86 version did you use?

Using the command it comes up as 'iio'

The build I use is LOS RC1, I got the build from a Thinkpad 8 group as all the function works out of the box (sound was not, but i can easily fix it)

Which version is it exactly? Check

This seems to be a custom version
so I'm still not sure what sensors HAL it uses.

Please check if you have this file:

Hi. My name is Ludger and I'm from Germany. I installed Android as second OS on my 2in1 Acer Switch One10 SW01-111

The item is running Win10Home. 

I made a partition with 15GB and installed BlissOS (Bliss-v11.13--OFFICIAL-20201113-1525_x86_64_k-k4.19.122-ax86-ga-rmi_m-20.1.0-llvm90_dgc-t3_gms_intelhd) with the Android X86-Installer. The sensor is regognized by the system but it's working revers: When I have the tablet in landscape format the apps are in portrait and squeezed. When I rotatet the tablet in portrait format the apps are shown correctly.

The guys from Bliss-Development on XDA told me to search for ro.iio.accel.x.opt_scale, ro.iio.accel.order in the android x86 google groups and so I found this group.

I've already updated the kernel with Gearlock to 5.10x but there is no change. Then I used the app Acceleromter Calibration free. The app shows that the sensor is working but it is not able to fix the reversproblem.

Can you help me to solve the problem

Regards

Ludger

[Ludger Müller]

Edit: The app Accelerometer Calibration shows the sensor type. It is an S0-i2c-KIOX000A:00
