[Q] Adding languages - direct pen input
I own a Note 3, SCL22, Japanese version from KDDI AU (I believe model SM-N900J - on the main site it goes as SM-N900JZKEKDI). As you know, there is that s pen writing feature which allows you to hand write pretty much anywhere in the phone by hovering over the typing field and clicking a little button there (called direct pen input in the settings). It supports 4 languages, English (UK/US), Japanese and Korean, and I was wondering if there is a way to get more? Apparently, it can't be done from the settings, nor does it seem to be available in the Samsung app shop. Is it possible to add more languages to it, either rooted or not? Preferably not, because my model hasn't been rooted yet, and God knows when it will be.
Thanks in advance.
