Looking For Tablet ROM With More Complete S-Pen Support

Hello. I have written an app that helps to improve the accuracy of the S-Pen. It works only on Note phones because Samsung has compiled some S-Pen device driver interfaces out of the tablet ROMs. It is not clear why they did this. I have asked Samsung but gotten no replies. I have confirmed that parts of the kernel code is commented out in the open source kernel code (and you can see that some of the interface files found on phones do not exist on the tablets). It seems that the tablets suffer from the same issues related to the S-Pen as do the phones and I have many people asking me to make my app work on their tablets. I cannot do so with the stock ROMs because of the missing interface files.

So I am wondering if there any non-stock ROMs in which the S-Pen is more fully supported. The missing files are located on my phone in /sys/class/sec/sec_epen/ and the two files I need are called epen_hand and epen_rotation. If anyone knows of any ROMs for the S-Pen equipped tablets that provide these interface files, I would appreciate knowing and may be able to direct some folks to using them.

Thanks
