Finally got both auto rotation and inverted touch screen work.

For inverted touch screen, I run some code in terminal before run the calibration app.

su

mkdir -p /data/misc/tscal

touch /data/misc/tscal/pointercal

chown 1000.1000 /data/misc/tscal /data/misc/tscal/*

chmod 775 /data/misc/tscal

chmod 664 /data/misc/tscal/pointercal

Then run calibration app, touch the five points and restart.

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
