I'm running rooted, SGH-I337 loki'd with TWRP installed.
It does ask for SuperSu permission. So obviously you need to be rooted.
I have it installed on Graviton 4.3 TW, have not tested on any other ROM. I do not have the modded NoteIII launcher installed. I'm on Gravitons stock S4 launcher and also with Epic launcher installed it worked.
Again this is not my work, apk, nor did I have anything to do with its development. So I can't be responsible for your choice to install it wrong or sideways or upside down and backwards which in turn cause WWIII or world peace. Well if it causes world peace then yeah that's on me. Lmao
Just thought I would "dropbox" it and share.
