Teclast X4 (tablet) accelerometer does not work in Android-x86 but works in Windows10

[Александр Леонтьев]

Hello everyone. I have a tablet "Teclast X4". Windows 10 was installed when I bought this tablet. I installed Android-x86 else. But in Android-x86 does not work  accelerometer (Rotate-sensor tilt-sensor, G-sensor, axis-sensor). Can you please add a support of accelerometer of Teclast X4?

I opened Device Manager in Windows10 and found  that Teclast X4 uses "Kionix KXCJ9 3-axis accelerometer".

If you need any info or any tests of Teclast X4 I am ready to do it!

It is supported. Search for the words "screen rotation" on the forum. A few other Teclast only, myself included, had the same problem.

you may want to search this forum first. I have a teclast x98 tablet and had the same issue. Sulution is as follows 

for auto rotation, edit /etc/init.sh

try going into init.sh and scroll down to init_hal_sensors function and after the last "fi" statement insert the following:

has_sensors=true

hal_sensors=iio

set_property ro.iio.accel.quirks no-trig #insert this line if screen is 90 degree rotation instead of 180, it exchanges Y and X axis

set_property ro.iio.accel.x.opt_scale -1 #Use one or more of them, depends on which axes are inverted. 

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

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

I found a solution how to make rotate-sensor works fine in Teclast X4
I edited /etc/init.sh this way:
I scrolled down to init_hal_sensors function and after the last "fi" statement insert the following:

has_sensors=true
hal_sensors=iio
set_property ro.iio.accel.quirks no-trig

set_property ro.iio.accel.order 102


So I received that:
elif [ "$hal_sensors" != "kbd" ]; then
has_sensors=true
fi

has_sensors=true
hal_sensors=iio
set_property ro.iio.accel.quirks no-trig

set_property ro.iio.accel.order 102

set_property ro.hardware.sensors $hal_sensors
set_property config.override_forced_orient ${HAS_SENSORS:-$has_sensors}
}

function create_pointercal()
{

After reboot rotation works well
