After a few weeks using PA v3.6, seems like it not suite for me where I'm using the s-pen much to do photo editing and drawing. PA s-pen is just slow and not so accurate compare to stock firmware/custom rom. Samsung already optimize the s-pen.
Now I'm back to TW. Guess what I'm using? I will answer you later :)
TW Custom Rom camera and video more robust and suitable for heavy duty and a lots of taking picture and videos. PA can't handle long taking picture and videos. It just hang and reboot it self.
This is my experience, I don't know yours.
