Bless you, Xposed Framework. Thou art the last refuge of power users whose hardware has been forsaken by manufacturer and ROM developer alike. The root-enabled tool has a new module that back-ports a bunch of Android Nougat features to earlier versions of the OS. It’s called AndroidN-ify, and the latest update includes a tweak that exposes Google’s fancy new voice-controlled Assistant search tool to users on Android 6.0. An earlier build.prop tweak allowed Android 7.0 users to try Assistant on non-Pixel phones, which won’t be officially supported when the new hardware launches.
