If you're Galaxy S6 or S6 Edge is rooted, you have probably been waiting around for the release of Xposed. Developer "Wanam" has released a build of the Xposed framework for Lollipop on Samsung devices which is fully functional on the Galaxy S6 and S6 Edge. This should also support upcoming Samsung Arm64 devices. It has taken so long to get Xposed on Lollipop Samsung devices due to the fact that Samsung made some pretty hefty changes to ART. With Xposed you will be able to apply pretty much any Rom customization to your phone with only root. Head to the link below for download and install instructions.
