p31xx_hwrotation_0

[QUOTE=ketut.kumajaya;45070146]You could try another kernel with hwrotation=0. Maybe just odd behavior touchscreen and wrong orientation camera :D
[CODE]
# Galaxy Tab 2 7.0 auto rotation script
# Ketut P. Kumajaya, June 2013

# parsing build.prop
if busybox [ $(busybox cat /system/build.prop | busybox grep -c ro.sf.hwrotation=270) -eq 1 ]; then
  # make sure the touchcreen driver in portrait mode
  echo 1 > /sys/devices/virtual/sec/tsp/pivot
else
  # make sure the touchcreen driver in landscape mode
  echo 0 > /sys/devices/virtual/sec/tsp/pivot
  # set accelerometer and geomagnetic sensor, landscape mode
  position=$(busybox find /sys/devices/virtual/input/ -type f -name name | busybox xargs busybox grep '^accelerometer$' | busybox sed 's@name:accelerometer@position@')
  echo -n 7 > $position
  position=$(busybox find /sys/devices/platform/omap/omap_i2c.4/i2c-4/4-002e/input/ -type f -name name | busybox xargs busybox grep '^geomagnetic$' | busybox sed 's@name:geomagnetic@position@')
  echo -n 7 > $position
fi
[/CODE]
Since codeworkx added pivot mode to touchscreen driver + my fix for runtime setting, you can adapt above code as an init.d script using stock kernel.[/QUOTE]
