This module was developed for AOSP based roms. Don't expect it to work on heavily modified non AOSP based roms like Sense, Touchwiz (Please don't give 1 star rate if this is your case).
Should be compatible with some other navigation bar customization modules.
It's recommended to do a nandroid backup if you're using the app for the first time.
