Hello everybody. I have a Oneplus One with Cyanogenmod 12 Nightly installed and Ak Kernel, and i've installed GravityBox Lp on Xposed Installer. GravityBox Open a window where it says that it supports only "pure" versions of Android, and custom rom may cause some bad issues. Is this true? Can i use GB, or do I have to uninstall it? Help me
