Recognized contributor wanam has released a version of Xposed that should work on all Galaxy S6 variants and he hopes that it will support upcoming Samsung arm64 devices. It is still in an experimental phase, however, and it has been confirmed as working so far on selected tested modules. As users of Samsung devices may know, they made significant changes to ART without providing resources, which is why in Wanam’s opinion it has taken a while for Xposed to be made functional.
