Enable Pen Mode - Any pen or pencil works as stylus!

AOKP introduced pen mode for Z1 and I could enable it on stock ROM!
Xperia Z Ultra can use the pen or pencil made of wood or metal as stylus, but Z1's screen also supports it and Sony disabled it for some reason.

root is needed to enable this.

To enable pen mode, there's three methods.
One of them is enough.
● Create init.d script in /system/etc/init.d (requires init.d support):
Code:
#!/system/bin/sh
chown system:system /sys/devices/virtual/input/clearpad/pen
echo 1 > /sys/devices/virtual/input/clearpad/pen
● Add these lines at the bottom of /system/etc/hw_config.sh:
Code:
chown system:system /sys/devices/virtual/input/clearpad/pen
echo 1 > /sys/devices/virtual/input/clearpad/pen
● Use toggle app
I created pen mode enable/disable toggle app with Tasker.

Now you can use anything made of wood, metal or rubber.
I couldn't use a plastic pen, though...

I recommend changing one value in /system/usr/idc/clearpad_pen.idc for more accuracy.
Change
Code:
# Pressure
touch.pressure.scale = 0.2
to
Code:
# Pressure
touch.pressure.scale = 0.1
works for me.

In /sys/devices/virtual/input/clearpad/,
there is "grove" but I could only show circle with pen and I couldn't use with glove.

It was root explorer that cose problem with folder,
with es explorer i can see inside folder and there is pen file with content 1 but i tried with ball pen and it didn't work,
could this be because of screen protector?

Ok it works now strange there is part of screen where it doesn't detect pen.

OP - good job
